- the count tables 55 and 82 may have multiple column elements.
- Each of the plurality of column elements may be associated with a combination.
- the combination is a combination of the culture conditions (eg, dilution ratio, culture time) of the test individual and the bacterial species (eg, common viable bacteria, Escherichia coli).
- Each column element has a different combination of culture conditions and bacterial species.
- the first row element and the second row element are different in at least one of culture conditions and bacterial species. This would make it possible to group cells corresponding to a plurality of combinations of various culture conditions and various bacterial species into one row for a certain test individual.
- the table management unit determines whether the row element specified by the user (designated row element) among the multiple row elements held in the database is included in the new count table. It may be determined whether If it is determined that the designated row element is not included in the count table, the MCU 30 may determine whether the designated row element includes a cell of a new column element that is not included in the count table. If it is determined that the designated row element includes a cell of a new column element, the MCU 30 adds the new column element to a new count table. On the other hand, if the specified row element is already included in the count table, or if the specified row element does not include a cell of a new column element, the column element is not added to the count table. As a result, duplication of row elements and duplication of column elements in the table will be suppressed, and the table will be made more compact.
- the database may include a plurality of row elements in which a parent-child relationship is defined.
- the parent-child relationship may be such that the finished product is the parent and the ingredients constituting the finished product are the children.
- a certain finished product eg, sandwich
- its ingredients eg, ham, lettuce

Description
本発明は、コロニー計数装置、制御方法およびプログラムに関する。
The present invention relates to a colony counting device, a control method, and a program.
食品を製造する工場ではコロニーカウンタを用いて菌が商品に混入しているかどうかが検査される。検査者は、シャーレ内に培地を形成し、培地に食品サンプルを投入し、所定期間にわたり培養器等で培養する。その後、検査者は、培養器からシャーレを取り出して、コロニーカウンタでコロニー(細菌の群体)をカウントする。このようにコロニーカウンタのカウント精度は食品の衛生管理上で重要である。特許文献1によれば、同一種類の多数のコロニーを安定して釣菌するために、それぞれ照明方向が異なる複数の照明画像を取得し、複数の照明画像を比較することで培地上のほぼすべてのコロニーを顕在化することが提案されている。
At food manufacturing factories, colony counters are used to test whether bacteria are present in the products. The inspector forms a culture medium in a petri dish, puts a food sample into the culture medium, and incubates it in an incubator or the like for a predetermined period of time. Thereafter, the examiner takes out the petri dish from the incubator and counts colonies (bacterial colonies) using a colony counter. In this way, the counting accuracy of colony counters is important for food hygiene control. According to Patent Document 1, in order to stably catch a large number of colonies of the same type, a plurality of illumination images each having a different illumination direction are acquired, and by comparing the plurality of illumination images, almost all of the colonies on the culture medium can be harvested. It has been proposed to make colonies of
ところで、照明装置の種類によっては、コロニーを撮影して取得された検査画像にハレーションが発生してしまうことがある。ハレーションは、検査画像に白飛び画素(画素値が最大値に飽和した画素)を発生させるため、コロニーを正確に計数することが困難となる。そこで、本発明は、コロニーの計数精度を向上させることを目的とする。
By the way, depending on the type of illumination device, halation may occur in an inspection image obtained by photographing a colony. Halation causes blown-out pixels (pixels whose pixel values are saturated to the maximum value) in the inspection image, making it difficult to accurately count colonies.

PC1bは、通信回路34は、スマートフォンやタブレット端末などの端末装置1cと無線通信を実行してもよい。端末装置1cは、カウント表55を表示したり、カウント表55から作成された検査リストを表示したりしてもよい。検査リストは、シャーレ番号、サンプル名、菌種、培地、希釈倍率、培養時間などを含み、ユーザが検査個体をシャーレ15に準備する際に参照される。
The communication circuit 34 of the PC 1b may perform wireless communication with a terminal device 1c such as a smartphone or a tablet terminal.

The test list includes petri dish number, sample name, bacterial species, culture medium, dilution ratio, culture time, etc., and is referred to when the user prepares test specimens in petri dish 15.
[検査手順] 一般的な検査手順は以下のとおりである。(1)ユーザは、手書きで検査リストを作成する。検査リストは、複数の行を含み、各行は、シャーレ番号、菌種、希釈倍率、カウント数、コメント(サンプル品名など)を書き込み可能となっている。なお、ここでシャーレ番号とは、培地の種類や希釈倍率などの培養条件を特定するために予め所定のルールで割り当てられた識別情報である。(2)ユーザは、検査リストにしたがってシャーレのふたに番号を書き込むか、または、シャーレに予め書き込まれた番号を検査リストに書き込む。(3)ユーザは、検査リストに書き込まれている希釈倍率にしたがって培地を作成する。検査リストに希釈倍率が書き込まれていなければ、ユーザは、実際の希釈倍率を検査リストに書き込む。(4)ユーザは、各シャーレの培地にサンプルを投入(混釈)する。ユーザは、検査リストのコメント欄にサンプル名を書き込む。(5)ユーザは、培養器にシャーレを投入する。(6)所定時間が経過すると、ユーザは、培養器からシャーレを取り出して、コロニーの個数をカウントする。たとえば、ユーザは、シャーレの底面側からコロニーを透かし見ながら、コロニーの位置に油性ペンでカウント済みのマークを付与して行く。コロニーの個数は検査リストに書き込まれる。なお、ユーザは、目視で菌種を確かめながら、菌種ごとのコロニーの個数をカウントしてもよい。この場合、ユーザは、各シャーレについて菌種ごとのコロニーの個数を検査リストに書き込む。(7)ユーザは、PCを起動し、検査リストに書き込まれている数値および文字を読み取りながら、表計算ソフトウエアに、入力する。表計算ソフトウエアのマクロ機能などを使用して、コロニーの個数が集計される。
[Inspection procedure] The general inspection procedure is as follows. (1) The user creates an inspection list by hand. The test list includes a plurality of lines, and each line allows writing of petri dish number, bacterial species, dilution ratio, count number, and comments (sample product name, etc.). Note that the petri dish number here is identification information that is assigned in advance according to a predetermined rule in order to specify culture conditions such as the type of medium and dilution ratio. (2) The user writes a number on the lid of the petri dish according to the test list, or writes the number previously written on the petri dish in the test list. (3) The user creates a culture medium according to the dilution factor written in the test list. If the dilution factor is not written in the test list, the user writes the actual dilution factor in the test list. (4) The user puts (mixes) the sample into the culture medium of each petri dish. The user writes the sample name in the comment field of the test list. (5) The user puts the petri dish into the incubator. (6) After a predetermined period of time has passed, the user takes out the petri dish from the incubator and counts the number of colonies. For example, while looking through the colonies from the bottom side of the Petri dish, the user marks the positions of the colonies with a permanent marker to indicate that they have been counted. The number of colonies is written into the inspection list. Note that the user may count the number of colonies for each type of bacteria while visually confirming the types of bacteria. In this case, the user writes the number of colonies for each bacterial species in the test list for each petri dish. (7) The user starts up the PC and inputs the numbers and characters written in the inspection list into the spreadsheet software while reading them. The number of colonies is tallied using the macro function of spreadsheet software.
このように、従来の検査手順では、手書きで検査リストが作成されており、これはユーザにとって非常に面倒な作業であった。また、検査リストに書き込まれた数値等を表計算ソフトウエアのシートに転記する際に誤入力があると、集計結果も誤ってしまう可能性があった。仮に、コロニーの個数をコロニーカウンタによって自動的に取得できたとしても、依然として、従来手法では、検査リストの作成と、コロニー個数の検査リストへの書き込みと、検査リストから表計算ソフトウエアのシートへの転記は、いずれも手書きであり、誤記入および誤入力の可能性があった。
As described above, in the conventional inspection procedure, an inspection list is created by hand, which is a very troublesome task for the user. Furthermore, if there is an incorrect input when transcribing numerical values written in the inspection list onto a sheet of spreadsheet software, there is a possibility that the tabulation results will also be incorrect. Even if the number of colonies could be automatically obtained using a colony counter, the conventional method still requires creating an inspection list, writing the number of colonies to the inspection list, and converting the inspection list to a spreadsheet software sheet. All transcriptions were handwritten, and there was a possibility of errors or typos.
そこで、本実施例では、PC1bにより電子的な検査リストを作成し、電子的な検査リストにしたがってコロニーを計数し、当該計数結果を電子的な検査リストに直接入力し、入力された個数を集計することが提案される。これにより、コロニーの計数結果についての事後処理に関するユーザの負担が軽減されるだろう。また、ユーザによる手書き、または、手入力が減少するため、誤入力も減少し、検査精度も向上するであろう。
Therefore, in this embodiment, an electronic inspection list is created using the PC1b, colonies are counted according to the electronic inspection list, the counting results are directly input into the electronic inspection list, and the input number is totaled. It is suggested that This will reduce the burden on the user regarding post-processing of colony counting results. Furthermore, since handwriting or manual input by the user is reduced, erroneous input will also be reduced and inspection accuracy will be improved.
[検査リスト(カウント表)の作成] 図5は、PC1bの表示装置37に表示されるカウントアプリケーションプログラムのUI50を示している。カウントアプリケーションプログラムは記憶装置35に記憶されており、MCU30により実行される。UI50は、カウントアプリケーションプログラムが有している複数の機能を切り替えるためのボタン、リンクまたはタブなどを有している。
[Creation of inspection list (count table)] FIG. 5 shows the UI 50 of the count application program displayed on the display device 37 of the PC 1b. The count application program is stored in the storage device 35 and executed by the MCU 30. The UI 50 includes buttons, links, tabs, etc. for switching between multiple functions of the counting application program.
UI50は、表作成領域51と、DB表示領域61とを有している。DBはデータベースの略称である。表作成領域51は、少なくともカウント表55を表示する。タイトル表示部52は、カウント表55に付与されたタイトル(名称)の入力をキーボード32から受け付けて表示する。ボタン53は各セルのカウントの実施/非実施を切り替えるボタンである。ボタン54は、カウント表55に列を追加することを指示するボタンである。平均化設定部56は、カウント結果の平均化を実行するかどうかを指示するためのチェックボックスと、平均化の対象となるカウント値の数(=カウントの反復回数)の選択部と、を有する。
The UI 50 has a table creation area 51 and a DB display area 61. DB is an abbreviation for database. The table creation area 51 displays at least a count table 55. The title display section 52 receives the input of the title (name) given to the count table 55 from the keyboard 32 and displays it. The button 53 is a button for switching execution/non-execution of counting each cell. The button 54 is a button for instructing to add a column to the count table 55. The averaging setting unit 56 includes a check box for instructing whether to average the count results, and a selection unit for selecting the number of count values to be averaged (=the number of repetitions of counting). .
DB表示領域61は、予め登録されたカウント項目のひな型の一覧(例:サンプルDB40)を表示する。ここで、カウント項目とは、カウント表55における一行に相当する。カウント項目は、通常、検査対象物の名称(サンプル名)により区別される。名称表示部62は、予め登録されているひな型の名称(サンプル名)を表示する。インジケータ63は、サンプル名に対して関連付けられている分類タグを視覚的に表示するオブジェクトである。分類タグとは、ユーザによって定義された分類(例:主食、総菜、デザート)を示すタグである。たとえば、インジケータ63は、色の違いによって分類タグの違いを表現してもよい。インジケータ63は、インジケータ63の形状の違いによって分類タグの違いを表現してもよい。ボタン67は、あるサンプル名に対して親子関係にある1つ以上のサブ項目を展開して表示するためのボタンである。親子関係とは、あるサンプルと、そのサンプルを構成する複数の具材との関係をいう。たとえば、サンドイッチを親とすると、サンドイッチを構成する具材(例:ハム、レタス、玉子)は子となる。ボタン64は、対応するひな型をカウント表55に追加することを指示するボタンである。このように予めサンプルDB40を用意しておくことで、ユーザは、カウント表55を容易に作成できるようになる。
The DB display area 61 displays a list of templates of count items registered in advance (eg, sample DB 40). Here, the count item corresponds to one line in the count table 55. Count items are usually distinguished by the name of the object to be inspected (sample name). The name display section 62 displays the name of the model (sample name) registered in advance. The indicator 63 is an object that visually displays the classification tag associated with the sample name. The classification tag is a tag indicating a classification (eg, staple food, prepared dish, dessert) defined by the user. For example, the indicator 63 may represent different classification tags by different colors. The indicators 63 may express different classification tags by different shapes of the indicators 63. The button 67 is a button for expanding and displaying one or more sub-items in a parent-child relationship with respect to a certain sample name. Parent-child relationship refers to the relationship between a certain sample and a plurality of ingredients that make up the sample. For example, if a sandwich is the parent, the ingredients that make up the sandwich (eg, ham, lettuce, egg) are the children. The button 64 is a button for instructing to add the corresponding model to the count table 55. By preparing the sample DB 40 in advance in this way, the user can easily create the count table 55.
図5に示された事例では、ユーザがサンドイッチに関連付けられたボタン64を押すと、MCU30は、カウント表55に一行を追加し、追加された行のID表示セルにIDとして"1"を表示し、追加された行においてサンプル名を表示するセルに「サンドイッチ」を表示する。IDは識別情報の略称である。すなわち、IDやサンプル名は行単位で設定されるものであり、「行に対する設定」である。さらに、MCU30は、サンプルDB40に登録されているサンドイッチの検査条件を記憶装置35から読み出し、カウント表55に新規の列を追加し、新規の列に、読み出した検査条件を表示する。この例では、検査条件は、菌種(例:一般生菌/大腸菌)、培地の希釈倍率、サンプルの培養時間などを含んでいる。各列は、たとえば、菌種のセル、希釈倍率のセル、培養時間のセルおよびカウント値のセルを含む。すなわち、菌種や希釈倍率、培養時間は列単位で設定されるものであり、「列に対する設定」である。この例では、まだ、検査の実行前であり、カウント値が入手されていないため、カウント値のセルには何も入力されていない。サンドイッチについての一つ目の検査項目は、一般生菌について希釈倍率として100倍の培地を使用し、培養時間として48時間が適用されることである。サンドイッチについての二つ目の検査項目は、一般生菌について希釈倍率として1000倍の培地を使用し、培養時間として48時間が適用されることである。このように、MCU30は、検査項目の個数に応じて列を追加する。
In the example shown in FIG. 5, when the user presses the button 64 associated with sandwich, the MCU 30 adds one row to the count table 55 and displays "1" as the ID in the ID display cell of the added row. Then, in the added row, "Sandwich" is displayed in the cell that displays the sample name. ID is an abbreviation for identification information. That is, the ID and sample name are set for each row, and are "settings for rows." Furthermore, the MCU 30 reads out the sandwich inspection conditions registered in the sample DB 40 from the storage device 35, adds a new column to the count table 55, and displays the read inspection conditions in the new column. In this example, the test conditions include the type of bacteria (eg, common viable bacteria/E. coli), the dilution ratio of the medium, the culture time of the sample, and the like. Each column includes, for example, a cell for bacterial species, a cell for dilution ratio, a cell for culture time, and a cell for count value. That is, the bacterial species, dilution ratio, and culture time are set for each row, and are "settings for each row." In this example, the test has not yet been executed and the count value has not yet been obtained, so nothing is entered in the count value cell. The first inspection item for sandwiches is that a medium with a dilution rate of 100 times is used for general viable bacteria, and a culture time of 48 hours is applied. The second inspection item for sandwiches is that a medium with a dilution rate of 1000 times is used for general viable bacteria, and a culture time of 48 hours is applied. In this way, the MCU 30 adds columns according to the number of inspection items.
図6は、ユーザがキムチに関連付けられたボタン64を押すと、MCU30は、サンプルDB40に登録されているキムチの検査条件を記憶装置35から読み出し、読み出された検査条件に対応する行と列をカウント表55に追加する。
FIG. 6 shows that when the user presses a button 64 associated with kimchi, the MCU 30 reads out the test conditions for kimchi registered in the sample DB 40 from the storage device 35, and rows and columns corresponding to the read test conditions. is added to the count table 55.
この例で、キムチは、二つの検査項目を有している。キムチについての一つ目の検査項目は、一般生菌について希釈倍率として100倍の培地を使用し、培養時間として48時間が適用されることである。これは、サンドイッチについての一つ目の検査項目と共通している。そのため、MCU30は、キムチのひな型に含まれている一つ目の検査項目を破棄し、新規の列として追加しない。キムチについての二つ目の検査項目は、大腸菌について希釈倍率として100倍の培地を使用し、培養時間として24時間が適用されることである。MCU30は、これを新規の列としてカウント表55に追加する。
In this example, kimchi has two inspection items. The first inspection item for kimchi is that a medium with a dilution rate of 100 times is used for general viable bacteria, and a culture time of 48 hours is applied. This is common to the first inspection item for sandwiches. Therefore, the MCU 30 discards the first inspection item included in the kimchi model and does not add it as a new column. The second inspection item for kimchi is that a medium with a dilution rate of 100 times is used for E. coli, and a 24-hour incubation time is applied. The MCU 30 adds this to the count table 55 as a new column.
なお、サンドイッチについては大腸菌に関する検査は実行されない。そのためカウント値のセルには「非検査」を示す文字または画像が表示されてもよい。同様に、キムチについては一般生菌について希釈倍率として1000倍の培地を使用する検査は実行されない。そのため、カウント値のセルには「非検査」を示す文字または画像が表示されてもよい。
Please note that sandwiches will not be tested for E. coli. Therefore, characters or images indicating "non-inspection" may be displayed in the count value cell. Similarly, for kimchi, tests using a medium with a dilution ratio of 1000 times for general viable bacteria are not performed. Therefore, characters or images indicating "non-inspection" may be displayed in the count value cell.
なお、カウントの実施・非実施はカウント反転ボタン53の操作により実行することもできる。サンドイッチについて、大腸菌に対応するセルを選択した状態で、カウント反転ボタン53が操作されると、MCU30は、「非検査」を示す文字または画像を表示するか、カウント結果を入力するために空欄とするのかを切り替えることができてもよい。
Note that counting can also be carried out or not carried out by operating the count inversion button 53. Regarding the sandwich, when the count reversal button 53 is operated with a cell corresponding to E. coli selected, the MCU 30 displays text or an image indicating "not tested", or displays a blank field for inputting the count result. It may also be possible to switch between
図5および図6が示すように検索ボックス65やタグ検索絞り込みボタン66が追加されてもよい。サンプルDB40に登録されているひな型の個数が多くなると、DB表示領域61は、一度にすべてのひな型を表示することができなくなる。そこで、MCU30は、検索ボックス65に入力された文字に基づき記憶装置35から検索してひな型を抽出し、DB表示領域61に検索結果を表示してもよい。また、タグ検索絞り込みボタン66が押されると、MCU30は、指定した分類タグでフィルタされたサンプル品だけを表示してもよい。たとえば、複数のサンプル品に対して同じ分類タグが付与されていてもよい。この場合、選択された分類タグが付与されている複数のサンプル品をカウント表55へ追加する。
As shown in FIGS. 5 and 6, a search box 65 and a tag search refinement button 66 may be added. When the number of templates registered in the sample DB 40 increases, the DB display area 61 cannot display all the templates at once. Therefore, the MCU 30 may search the storage device 35 based on the characters input in the search box 65 to extract a template, and display the search results in the DB display area 61. Furthermore, when the tag search refinement button 66 is pressed, the MCU 30 may display only sample products filtered by the specified classification tag. For example, the same classification tag may be assigned to multiple sample products. In this case, a plurality of sample products to which the selected classification tag is attached are added to the count table 55.
図7は、新規の行を追加する別の手順を示している。ユーザは、新規の行におけるサンプル名表示セルをポインタ57で選択し、キーボード32を通じてサンプル名を先頭の文字から順番に入力して行く。MCU30は、入力された一以上の文字でサンプルDB40を検索し、入力候補となるサンプル名を候補表示部58に表示する。この例では、サンプル名表示セルに「ミックス」が入力されたため、MCU30は「ミックス」をサンプル名として含むひな型を検索し、「ミックスジュース」を発見し、候補表示部58に「ミックスジュース」を表示する。ここで、ユーザが、ポインタ57によって候補表示部58に表示された「ミックスジュース」を選択すると、MCU30は、ミックスジュースの検査条件を記憶装置35から読み出し、読み出された検査条件に応じて列を追加する。これにより、ミックスジュースのセルに検索条件が関連付けられることになる。
FIG. 7 shows another procedure for adding new rows. The user selects the sample name display cell in the new row with the pointer 57 and inputs the sample name using the keyboard 32 in order from the first character. The MCU 30 searches the sample DB 40 using the input one or more characters, and displays sample names as input candidates on the candidate display section 58. In this example, since "mix" is input in the sample name display cell, the MCU 30 searches for a template that includes "mix" as a sample name, finds "mixed juice", and displays "mixed juice" in the candidate display section 58. indicate. Here, when the user selects "mixed juice" displayed on the candidate display section 58 with the pointer 57, the MCU 30 reads out the test conditions for the mixed juice from the storage device 35, and selects a column according to the read test conditions. Add. As a result, the search condition will be associated with the mixed juice cell.
図8は、新規にカウント表を作成する場合のUI50を示している。たとえば、MCU30は、アプリケーションプログラム39と並行して表計算ソフトウエアを起動することができる。
FIG. 8 shows the UI 50 when creating a new count table. For example, the MCU 30 can launch spreadsheet software in parallel with the application program 39.
図9は、表計算ソフトウエアのシート70を示している。MCU30は、表計算ソフトウエアにおいて選択されたシート70ま
たはセル群について、UI50へのコピーペーストの指示を受け付ける。これにより、MCU30は、図6に示されたカウント表55を作成してもよい。 FIG. 9 shows a sheet 70 of spreadsheet software. The MCU 30 receives a copy-paste instruction to the UI 50 for the sheet 70 or cell group selected in the spreadsheet software. Thereby, the MCU 30 may create the count table 55 shown in FIG. 6.
たはセル群について、UI50へのコピーペーストの指示を受け付ける。これにより、MCU30は、図6に示されたカウント表55を作成してもよい。 FIG. 9 shows a sheet 70 of spreadsheet software. The MCU 30 receives a copy-paste instruction to the UI 50 for the sheet 70 or cell group selected in the spreadsheet software. Thereby, the MCU 30 may create the count table 55 shown in FIG. 6.
図10は、すでにカウント値が入力されたカウント表82を呼び出して新規のカウント表55を作成する手順を説明する図である。MCU30は、検索ボックス65に入力されたファイル名に対応するファイルを記憶装置35から読み出し、そのファイルの属性を属性表示部80に表示してもよい。MCU30は、表作成領域51に、読み出されたカウント表82を表示する。図10が示すように、カウント値のセルにはカウント値が入力済みである。MCU30は、新規作成ボタン81が押されたことを検知すると、読み出されたカウント表82を構成しているカウント値のセルに入力されているカウント値をすべて削除し、新規のカウント表55を作成する。図11は、すでにカウント値が入力されたカウント表82から作成された新規のカウント表55を示している。カウント値を削除する代わりに、カウント値が0にリセットされてもよい。
FIG. 10 is a diagram illustrating a procedure for creating a new count table 55 by calling the count table 82 in which count values have already been input. The MCU 30 may read the file corresponding to the file name input into the search box 65 from the storage device 35 and display the attribute of the file on the attribute display section 80. The MCU 30 displays the read count table 82 in the table creation area 51. As shown in FIG. 10, a count value has already been input into the count value cell. When the MCU 30 detects that the new creation button 81 has been pressed, it deletes all the count values input in the count value cells that make up the read count table 82 and creates a new count table 55. create. FIG. 11 shows a new count table 55 created from the count table 82 in which count values have already been input. Instead of deleting the count value, the count value may be reset to zero.
なお、MCU30は、複数のカウント表82をマージして一つのカウント表55を作成してもよい。この場合、MCU30は、複数のカウント表82を分析し、重複する行と列を削除し、新規のカウント表55を作成する。
Note that the MCU 30 may create one count table 55 by merging the plurality of count tables 82. In this case, the MCU 30 analyzes the plurality of count tables 82, deletes duplicate rows and columns, and creates a new count table 55.
図12は、平均化を含むカウント表55の作成方法を説明するための図である。この例では、平均化がまだ適用されていないため、一つのサンプル名について一つの行が設けられている。この状態で平均化設定部56がチェックされ、反復回数として「2」が選択されると、MCU30は、図11に示されたUI50を表示する。図11が示すように、反復回数が「2」であることから、MCU30は、各サンプル名に関連付けられたカウント値の入力行を三つの行に分割するとともに、反復回数を示す列を追加する。この例では、三つの行のうち、一つ目の行は1回目の検査で取得されたカウント値が入力されるセルを有する。二つ目の行は2回目の検査で取得されたカウント値が入力されるセルを有する。三つ目の行は1回目の検査で取得されたカウント値と、2回目の検査で取得されたカウント値との平均値が入力されるセルを有する。このように、MCU30は、反復回数に応じて、カウント値が入力されるセルと平均値が入力されるセルとをカウント表55に追加してもよい。
FIG. 12 is a diagram for explaining a method of creating the count table 55 including averaging. In this example, there is one row for each sample name because averaging has not yet been applied. In this state, the averaging setting section 56 is checked, and when "2" is selected as the number of repetitions, the MCU 30 displays the UI 50 shown in FIG. 11. As shown in FIG. 11, since the number of repetitions is "2", the MCU 30 divides the input row of count values associated with each sample name into three rows, and adds a column indicating the number of repetitions. . In this example, of the three rows, the first row has a cell into which the count value obtained in the first test is input. The second row has cells into which the count values obtained in the second test are entered. The third row has a cell into which the average value of the count value obtained in the first test and the count value obtained in the second test is input. In this manner, the MCU 30 may add cells into which the count value is input and cells into which the average value is input to the count table 55 depending on the number of repetitions.
図13は、複数のサンプル間の親子関係の一例を示す。この例では、サンドイッチのインジケータ63が押されると、MCU30は、サンドイッチと親子関係を有する具材である「ハム」と「レタス」を選択可能にDB表示領域61に表示する。この状態で、「ハム」または「レタス」のボタン64が押されると、MCU30は、「ハム」または「レタス」の検査項目を記憶装置35から読み出し、カウント表55に追加する。図14は、「ハム」および「レタス」の各検査項目が記憶装置35から読み出されて、カウント表55に追加されたことを示す。親子関係を有するサンドイッチ、ハムおよびレタスが一括して登録されてもよい。たとえば、サンドイッチに関連付けられたボタン64が押されると、サンドイッチ、ハムおよびレタスがテーブル表55に一括して登録されてもよい。
FIG. 13 shows an example of a parent-child relationship between multiple samples. In this example, when the sandwich indicator 63 is pressed, the MCU 30 selectably displays "ham" and "lettuce", which are ingredients that have a parent-child relationship with the sandwich, in the DB display area 61. In this state, when the "ham" or "lettuce" button 64 is pressed, the MCU 30 reads the test item "ham" or "lettuce" from the storage device 35 and adds it to the count table 55. FIG. 14 shows that the test items "ham" and "lettuce" have been read from the storage device 35 and added to the count table 55. Sandwich, ham, and lettuce having a parent-child relationship may be registered all at once. For example, when the button 64 associated with sandwiches is pressed, sandwiches, ham, and lettuce may be registered in the table 55 all at once.
図15は、列を追加するためのダイアログ90を示している。UI50に設けられたボタン54が押されると、MCU30は、ダイアログ90を表示装置37に表示する。項目名設定部91は、列の項目名である菌種の名称の入力を受け付ける。列タイプ設定部92は、列のタイプがカウント列であるか、または、自由列であるかの設定を受け付ける。カウント列とは、カウント値が入力されるセルを含む列である。自由列とは、備考やコメントなど、ユーザが自由にテキスト、画像、その他の情報を入力可能な列である。希釈倍率設定部93は、希釈倍率の入力を受け付ける。培養時間設定部94は、培養時間の入力を受け付ける。アルゴリズム設定部95は、検査画像に適用される画像処理の設定を受け付ける。残渣除去とは、シャーレ15などに付着した残渣(例:ゴミ、汚れ、手書き)を画像処理によって低減するモードである。迅速モードとは、迅速な結果の確認を重視したモードであり、[0]従来よりも短い培養時間で培養されたシャーレ15を高感度で検査するモードである。培地タイプ設定部96は、培地の種類(例:一般生菌(白)、一般生菌(黒))などの選択を受け付ける。なお、一覧ボタン96aが押されると、MCU30は、記憶装置35から培地タイプの候補を読み出してリストを作成して表示装置37に表示してもよい。カウント設定部97は、メインカメラ11の撮影条件(例:露光時間)、照明の種類(例:明るさ、照明装置)、表示処理の種類、画像処理の種類などの設定を受け付ける。すなわち、ダイアログ90で受け付けられた菌種、希釈倍率、培養時間、アルゴリズム設定、培地タイプ、またはカウント設定は、デフォルトの設定として列ごとに設定される。
FIG. 15 shows a dialog 90 for adding columns. When the button 54 provided on the UI 50 is pressed, the MCU 30 displays a dialog 90 on the display device 37. The item name setting section 91 accepts input of the name of the bacterial species, which is the item name of the column. The column type setting section 92 accepts settings as to whether the column type is a count column or a free column. A count column is a column containing cells into which count values are input. A free column is a column in which the user can freely input text, images, and other information such as notes and comments. The dilution rate setting unit 93 receives input of a dilution rate. The culture time setting unit 94 receives input of culture time. The algorithm setting unit 95 receives settings for image processing applied to the inspection image. Residue removal is a mode in which residues (eg, dust, dirt, handwriting) attached to the Petri dish 15 or the like are reduced by image processing. The rapid mode is a mode that emphasizes quick confirmation of results, and is a mode in which [0] a Petri dish 15 cultured in a shorter culture time than conventional methods is inspected with high sensitivity. The culture medium type setting section 96 accepts selection of the type of culture medium (eg, general viable bacteria (white), general viable bacteria (black)), and the like. Note that when the list button 96a is pressed, the MCU 30 may read the medium type candidates from the storage device 35, create a list, and display the list on the display device 37. The count setting section 97 accepts settings such as photographing conditions (eg, exposure time) of the main camera 11, type of illumination (eg, brightness, lighting device), type of display processing, type of image processing, etc. That is, the bacterial species, dilution factor, culture time, algorithm settings, medium type, or count settings accepted in the dialog 90 are set for each column as default settings.
[カウント処理] 図16は、PC1bからヘッド装置1aを制御してカウント処理を実行中にPC1bの表示装置37に表示されるUI100を示している。カウント表領域101は、UI50を通じて編集されたカウント表55を表示する領域である。結果領域102は、ヘッド装置1aのメインカメラ11により取得された検査画像103を表示する領域である。なお、検査画像103は、動画像であってもよいし、静止画像であってもよい。一般に、メインカメラ11の露光時間の調整、リング照明装置12、13および同軸照明装置14の明るさ、点灯すべき発光素子の選択、画像処理の選択などを実行する際は、MCU30は、メインカメラ11により動画像を取得して、結果領域102に表示する。一方で、カウント処理を実行する際には、MCU30は、メインカメラ11により静止画像を取得して、結果領域102に表示する。
[Counting Process] FIG. 16 shows the UI 100 displayed on the display device 37 of the PC 1b while the PC 1b controls the head device 1a to execute the counting process. The count table area 101 is an area for displaying the count table 55 edited through the UI 50. The result area 102 is an area for displaying the inspection image 103 acquired by the main camera 11 of the head device 1a. Note that the inspection image 103 may be a moving image or a still image. Generally, when adjusting the exposure time of the main camera 11, brightness of the ring lighting devices 12, 13 and coaxial lighting device 14, selecting light emitting elements to be lit, selecting image processing, etc., the MCU 30 controls the main camera 11. 11, a moving image is acquired and displayed in the result area 102. On the other hand, when executing the counting process, the MCU 30 acquires a still image using the main camera 11 and displays it in the result area 102.
チェックボックス106は、カウント値領域104にカウント結果を表示するかどうかを選択するためのコントロールオブジェクトである。第一ソフトウエアボタン105aは、第一ハードウエアボタン8aと同一の機能を有するボタンである。第二ソフトウエアボタン105bは、第二ハードウエアボタン8bと同一の機能を有するボタンである。この例では、第一ソフトウエアボタン105aには撮影の指示(撮影ボタン)が割り当てられている。第二ソフトウエアボタン105bには登録の指示(登録ボタン)が割り当てられている。図15においては、第二ソフトウエアボタン105bが破線で示されているが、これは操作不可能であることを意味する。
The check box 106 is a control object for selecting whether or not to display the count result in the count value area 104. The first software button 105a is a button that has the same function as the first hardware button 8a. The second software button 105b is a button that has the same function as the second hardware button 8b. In this example, a shooting instruction (shooting button) is assigned to the first software button 105a. A registration instruction (registration button) is assigned to the second software button 105b. In FIG. 15, the second software button 105b is shown with a broken line, which means that it is inoperable.
ユーザは、カウント表領域101に表示されたカウント表に含まれる複数のセルのうち、ステージ5にセットしたシャーレ15に対応するセルをポインタ57によりクリックして選択する。図16に示すように、どのセルがユーザにより選択されたかが分かるように、ポインタ57により選択されたセルは、強調して表示されてもよい。各セルには、予め検査条件(コロニーを二値化する際の感度、照明装置の種類、明るさなど)が関連付けられて記憶装置35に保存されている。MCU30は、選択されたセルに関連付けられている検査条件を記憶装置35から読み出して、ヘッド装置1aに送信する。ヘッド装置1aのMCU20は受信された検査条件にしたがってメインカメラ11、リング照明装置12、13、および同軸照明装置14を制御し、画像を取得して、PC1bへ送信する。なお、別のセルが選択されると、MCU30は、選択されたセルに関連付けられている検査条件を記憶装置35から読み出して、ヘッド装置1aに送信する。ヘッド装置1aのMCU20は受信された検査条件にしたがってメインカメラ11、リング照明装置12、13および同軸照明装置14を制御し、画像を取得して、PC1bへ送信する。このように、ユーザは、セルを選択することで、検査条件を変更することができる。
The user clicks with the pointer 57 to select a cell corresponding to the Petri dish 15 set on the stage 5 from among the plurality of cells included in the count table displayed in the count table area 101. As shown in FIG. 16, the cell selected by the pointer 57 may be highlighted and displayed so that the user can see which cell has been selected. Inspection conditions (sensitivity when binarizing colonies, type of lighting device, brightness, etc.) are associated with each cell in advance and stored in the storage device 35. The MCU 30 reads the inspection conditions associated with the selected cell from the storage device 35 and transmits them to the head device 1a. The MCU 20 of the head device 1a controls the main camera 11, ring illumination devices 12, 13, and coaxial illumination device 14 according to the received inspection conditions, acquires images, and transmits them to the PC 1b. Note that when another cell is selected, the MCU 30 reads the inspection conditions associated with the selected cell from the storage device 35 and transmits them to the head device 1a. The MCU 20 of the head device 1a controls the main camera 11, ring illumination devices 12, 13, and coaxial illumination device 14 according to the received inspection conditions, acquires images, and transmits them to the PC 1b. In this way, the user can change the inspection conditions by selecting a cell.
図17は、設定タブまたは設定ボタンをポインタ57にクリックすることで表示される検査条件の確認画面110を示す。これにより、ユーザは、各セルごとの検査条件を確認することができる。なお、セルをポインタ57により右クリックすることで、確認画面110が表示されてもよい。確認画面110に表示される情報としては、たとえば、サンプル名、培地の種類、希釈倍率、培養時間、シャーレ番号、コメント、撮影設定(落射照明のオンオフ、照明装置の種類、落射照明の明るさ、透過照明の明るさ、画像処理(ハイダイナミックレンジ"HDR"のオンオフ、リング除去のオンオフなどのカウント設定)などである。図17において、「上リング」とはリング照明装置12の略称である。「下リング」とはリング照明装置13の略称である。「全射」とは同軸照明装置14の略称である。ここで、MCU30は、菌種、希釈倍率、培養時間、アルゴリズム設定、培地タイプ、または撮影設定(カウント設定)について、図15に示すダイアログ90上で、列単位で、デフォルト値を設定するが、図17の確認画面110上で、各セルに対して個別に設定してもよい。
FIG. 17 shows an inspection condition confirmation screen 110 that is displayed when the pointer 57 clicks on the settings tab or button. This allows the user to check the inspection conditions for each cell. Note that the confirmation screen 110 may be displayed by right-clicking a cell with the pointer 57. The information displayed on the confirmation screen 110 includes, for example, sample name, type of medium, dilution factor, culture time, petri dish number, comment, imaging settings (on/off of epi-illumination, type of illumination device, brightness of epi-illumination, These include the brightness of transmitted illumination, image processing (count settings such as on/off of high dynamic range "HDR", on/off of ring removal, etc.) In FIG. 17, "upper ring" is an abbreviation for the ring illumination device 12. "Lower ring" is an abbreviation for the ring illumination device 13. "Surface" is an abbreviation for the coaxial illumination device 14. Here, the MCU 30 represents the bacterial species, dilution ratio, culture time, algorithm settings, and medium type. , or shooting settings (count settings), default values are set for each column on the dialog 90 shown in FIG. 15, but they can also be set individually for each cell on the confirmation screen 110 shown in FIG. good.
なお、セルに対してダブルクリックなどの特定の入力を受け付けることで、当該セルに対応する設定を一覧表示した確認画面110がUI100上に重畳して表示されてもよい。また、ポインタ57によりセルが選択されると、MCU30は、当該セルに対応する設定をUI100上に表示するようにしてもよい。
Note that by accepting a specific input such as double-clicking on a cell, the confirmation screen 110 displaying a list of settings corresponding to the cell may be displayed superimposed on the UI 100. Further, when a cell is selected by the pointer 57, the MCU 30 may display settings corresponding to the cell on the UI 100.
図18は、撮影ボタンである第一ソフトウエアボタン105aまたは第一ハードウエアボタン8aが押されると、MCU30が表示装置37に表示するUI100を示している。結果領域102には、シャーレ15の画像103(静止画像)が表示される。MCU30は、第一ソフトウエアボタン105aを撮影ボタンからカウントを指示するボタン(カウントボタン)に割り当てる。
FIG. 18 shows a UI 100 that the MCU 30 displays on the display device 37 when the first software button 105a or the first hardware button 8a, which is a shooting button, is pressed. In the result area 102, an image 103 (still image) of the petri dish 15 is displayed. The MCU 30 assigns the first software button 105a to a button (count button) that instructs counting from the shooting button.
図19は、カウントボタンである第一ソフトウエアボタン105aまたは第一ハードウエアボタン8aが押されると、MCU30が表示装置37に表示するUI100を示している。カウントボタンが押されると、MCU30は、ヘッド装置1aにコロニーのカウントを指示する。ヘッド装置1aのMCU20はカウント指示にしたがってコロニーをカウントし、カウント値をPC1bへ送信する。なお、カウント処理はMCU30により実行されてもよい。MCU30は、カウント値をカウント値領域104に表示する。この際には、MCU30は、カウント値をCFU/mL(単位体積(ミリリットル)あたりのコロニーの個数)に変換してカウント値領域104に表示してもよい。たとえば、カウント値領域104をポインタ57でクリックするごとに、MCU30は、カウント値のみ、CFU/mLのみ、カウント値+CFU/mLと順番に表示を切り替えてもよい。なお、CFUはコロニー形成単位の略称である。また、カウント値が取得されると、MCU30は、第一ソフトウエアボタン105aをカウントボタンから撮影ボタンに割り当て直す。さらに、MCU30は、登録ボタンに割り当てられている第二ソフトウエアボタン105bおよび第二ハードウエアボタン8bを操作不可能状態から操作可能状態に変更する。
FIG. 19 shows the UI 100 that the MCU 30 displays on the display device 37 when the first software button 105a or the first hardware button 8a, which is a count button, is pressed. When the count button is pressed, the MCU 30 instructs the head device 1a to count colonies. The MCU 20 of the head device 1a counts colonies according to the count instruction and transmits the count value to the PC 1b. Note that the counting process may be executed by the MCU 30. The MCU 30 displays the count value in the count value area 104. In this case, the MCU 30 may convert the count value into CFU/mL (number of colonies per unit volume (milliliter)) and display it in the count value area 104. For example, each time the count value area 104 is clicked with the pointer 57, the MCU 30 may switch the display in order of only the count value, only CFU/mL, and count value + CFU/mL. Note that CFU is an abbreviation for colony forming unit. Further, when the count value is acquired, the MCU 30 reassigns the first software button 105a from the count button to the shooting button. Further, the MCU 30 changes the second software button 105b and second hardware button 8b assigned to the registration button from an inoperable state to an operable state.
図20は、登録ボタンが押された状態を示している。MCU30は、現在選択中のセルに対してカウント値を書き込み、次のセルを選択中(注目セル)に変更してもよい。この例では、1行目のセルから2行目のセルに注目セル(アクティブセル)が変更されている。このように、MCU30が自動的に次のセルを選択することで、ユーザの負担が軽減される。なお、MCU30は、登録ボタンに割り当てられている第二ソフトウエアボタン105bおよび第二ハードウエアボタン8bを操作可能状態から操作不可能状態に戻す。
FIG. 20 shows a state in which the registration button is pressed. The MCU 30 may write a count value to the currently selected cell and change the next cell to be selected (the cell of interest). In this example, the cell of interest (active cell) is changed from the cell in the first row to the cell in the second row. In this way, the MCU 30 automatically selects the next cell, thereby reducing the burden on the user. Note that the MCU 30 returns the second software button 105b and second hardware button 8b assigned to the registration button from an operable state to an inoperable state.
図20に示されているUI100は、セルの表示対象の変更メニュー109を有している。図20では、変更メニュー109において「カウント数」が選択されているため、セルには、「100」が表示されている。
The UI 100 shown in FIG. 20 has a cell display target change menu 109. In FIG. 20, since "Count" is selected in the change menu 109, "100" is displayed in the cell.

すように、ユーザが変更メニュー109において「CFU/mL」を選択すると、MCU30は、セルの表示対象を「カウント数」から「CFU/mL」に変更する。これにより、ユーザは容易にセルの表示対象を切り替えることができる。 As shown in FIG. 21, when the user selects "CFU/mL" in the change menu 109, the MCU 30 changes the cell display target from "count number" to "CFU/mL". This allows the user to easily switch the cell display target.

This allows the user to easily switch the cell display target.
図22が示すように、ユーザが変更メニュー109において「コメント」を選択すると、MCU30は、セルの表示対象を「コメント」に変更する。これにより、ユーザは容易にセルの表示対象をコメントに切り替えることができる。また、このUI100においても、ユーザは、図22に示すように「コンタミ発生」などのコメントを直接入力できる。ここで、コメントとは、カウント表の一行に含まれる備考などである。
As shown in FIG. 22, when the user selects "comment" in the change menu 109, the MCU 30 changes the cell display target to "comment". This allows the user to easily switch the cell display target to comments. Also, in this UI 100, the user can directly input a comment such as "contamination has occurred" as shown in FIG. 22. Here, the comment is a note included in one line of the count table.
図23は、カウント値が入力済みであるセルをダブルクリックされると、MCU30が表示装置37に表示するUI100を示している。設定画面120は、ダブルクリックにより選択されたセルに関連付けられている検査条件のうちコロニーの検出アルゴリズムに関するパラメータを調整するためのコントロールオブジェクトを含む。スライドバー121は、たとえば、小粒子を画像処理により除去するための閾値を設定するためのコントロールオブジェクトである。スライドバー122は、コロニーの検出感度を調整するためのコントロールオブジェクトである。
FIG. 23 shows the UI 100 that the MCU 30 displays on the display device 37 when a cell in which a count value has been input is double-clicked. The settings screen 120 includes a control object for adjusting parameters related to the colony detection algorithm among the test conditions associated with the cell selected by double-clicking. The slide bar 121 is, for example, a control object for setting a threshold value for removing small particles through image processing. The slide bar 122 is a control object for adjusting colony detection sensitivity.
MCU30は、結果領域102に表示された画像103において、コロニーとして検出された部分にサークルなどのマークを重畳表示してもよい。スライドバー121、122の調整に応じて、MCU30がアルゴリズムを変更するため、コロニーを示すマークの位置と個数も変化する。これにより、ユーザは、適切な調整量を見出しやすくなるであろう。
In the image 103 displayed in the result area 102, the MCU 30 may display a mark such as a circle in a superimposed manner on a portion detected as a colony. Since the MCU 30 changes the algorithm according to the adjustment of the slide bars 121 and 122, the position and number of marks indicating colonies also change. This will make it easier for the user to find an appropriate amount of adjustment.
[ボタンの割り当て] 図24は、第一ハードウエアボタン8a(第一ソフトウエアボタン105a)と、第二ハードウエアボタン8b(第二ソフトウエアボタン105b)に割り当てられる機能の一例を示している。

カウント表の状態が「カウント表が表示されていない」状態であり、画像103が静止画像であり、かつ、アクティブセルの状態がカウント値入力済みであれば、第一ハードウエアボタン8a(第一ソフトウエアボタン105a)には撮影ボタンが割り当てられ、第二ハードウエアボタン8b(第二ソフトウエアボタン105b)には再登録ボタン(操作可能)が割り当てられる。
If the state of the count table is "the count table is not displayed", the image 103 is a still image, and the state of the active cell is that the count value has already been input, press the first hardware button 8a (the first A shooting button is assigned to the software button 105a), and a re-registration button (operable) is assigned to the second hardware button 8b (second software button 105b).
図17や図23が示すように、カウント表の状態が「カウント表が表示されていない」状態では、カウント表に代えて、検査条件を変更可能なUIが表示されている。したがって、検査条件が変更されると、カウント値も変化するため、ユーザには、変化後のカウント値をアクティブセルに書き込む(再登録)するかどうかをMCU30が問い合わせることになる。
As shown in FIGS. 17 and 23, when the state of the count table is "the count table is not displayed", a UI that allows the inspection conditions to be changed is displayed instead of the count table. Therefore, when the test conditions are changed, the count value also changes, and the MCU 30 asks the user whether or not to write (re-register) the changed count value into the active cell.
「カウント表が表示されていない」状態は、カウント結果が入力されたカウント表が表示され、かつ、カウント結果を再編集可能な状態であってもよい。図25は、再編集のための編集タブ124が設けられたUI100を示している。図24に表示された「カウント表が表示されていない」状態は、カウント結果が入力されたカウント表が表示され、かつ、編集タブ124がクリックされた状態であってもよい。図25において検査条件タブ123は、図17に示された検査条件の確認画面110を表示するためのタブである。上述されたように、確認画面110において照明やメインカメラ11の設定が変更可能となっている。
The state where "the count table is not displayed" may be a state where the count table into which the count results have been input is displayed and the count results can be re-edited. FIG. 25 shows the UI 100 provided with an edit tab 124 for re-editing. The "count table not displayed" state displayed in FIG. 24 may be a state in which the count table into which the count results have been input is displayed and the edit tab 124 is clicked. In FIG. 25, the inspection condition tab 123 is a tab for displaying the inspection condition confirmation screen 110 shown in FIG. 17. As described above, settings for lighting and the main camera 11 can be changed on the confirmation screen 110.
このように結果領域102に動画像が表示されているときにカウントボタンが押されると、動画像が静止画像に変更され、カウント結果が表示され、登録ボタンが操作可能となる。静止画像が表示されているときに登録ボタンが押されると、カウント結果がアクティブセルに書き込まれ、結果領域102は動画像を表示する状態に戻る。一度登録されたカウント結果が変更され、再登録ボタンが押されると、変更されたカウント結果がカウント表に上書きされ、結果領域102は動画像を表示する状態に戻る。結果領域102が静止画像を表示しているときに、撮影ボタン(撮りなおしボタン)が押されると、結果領域102は動画像を表示する状態に戻る。
If the count button is pressed while a moving image is being displayed in the result area 102 in this manner, the moving image is changed to a still image, the count result is displayed, and the registration button becomes operable. If the registration button is pressed while a still image is being displayed, the count result is written into the active cell, and the result area 102 returns to the state of displaying a moving image. When the once registered count result is changed and the re-registration button is pressed, the changed count result is overwritten on the count table and the result area 102 returns to the state of displaying a moving image. When the shooting button (re-shooting button) is pressed while the result area 102 is displaying a still image, the result area 102 returns to the state of displaying a moving image.
[カウント表の特定方法] ユーザは、シャーレ15で菌を培養したり、コロニーをカウントしたりする際にカウント表を見ることになる。ここで、カウント表を作成された日と、カウント表を目視して準備作業およびカウント作業を実行する日と、が異なっている場合がある。この場合、ユーザは、所望のカウント表を記憶装置35から読み出して表示装置37に表示させる必要がある。
[Method for specifying the count table] The user will look at the count table when cultivating bacteria in the Petri dish 15 or counting colonies. Here, the date on which the count table is created may be different from the date on which the count table is visually inspected and the preparation work and counting work are performed. In this case, the user needs to read out the desired count table from the storage device 35 and display it on the display device 37.
図26は、カウント表などのファイルを呼び出すファイルUI200を示している。ボタン210は、呼び出す対象としてカウント表を指定するためのボタンである。ファイルリスト211は、記憶装置35に記憶されたファイルを一覧212として表示する領域である。ボタン210が押されると、MCU30は、複数のファイルのうちカウント表に特有の拡張子を有するファイルのみをファイルリスト211に表示する。一覧212は、ID(通し番号)、タイトル、最終更新日、カウントが済んでいるかどうか、その他の情報を含む。
FIG. 26 shows a file UI 200 that calls a file such as a count table. Button 210 is a button for specifying a count table as a target to be called. The file list 211 is an area that displays files stored in the storage device 35 as a list 212. When the button 210 is pressed, the MCU 30 displays, in the file list 211, only files that have extensions specific to the count table among the plurality of files. The list 212 includes ID (serial number), title, last updated date, whether counting has been completed, and other information.
検索ボックス213は、一覧212に含まれる複数のファイルからさらに所望のファイルを検索するためのキーワードを入力されるボックスである。ボタン214は、カウント表を紙に印刷することで作成された検査リストに付与されている識別画像を読み取るためにフロントカメラ10を起動することを指示するためのボタンである。開くボタン215は、一覧212から選択されたカウント表を開くことを指示するボタンである。
The search box 213 is a box into which a keyword for further searching for a desired file from the plurality of files included in the list 212 is input. The button 214 is a button for instructing to start the front camera 10 in order to read the identification image added to the inspection list created by printing the count sheet on paper. The open button 215 is a button for instructing to open the count table selected from the list 212.
図27は、検査リスト220を示している。MCU30は検査リスト220をプリンタ38から出力してもよいし、端末装置1cの表示装置に出力してもよい。検査リスト220は、対応するカウント表55から作成されたリストである。カウント表55における情報の並ぶ順序と検査リスト220における情報の並ぶ順序とは異なっていてもよいし、一致していてもよい。検査リスト220は、表示装置37に表示されるカウント表55と同じであってもよい。また、検査リスト220にはカウント結果を記入する必要が無いため、カウント結果を記入するためのセルが省略されていてもよい。さらに、ユーザが検査リスト220を培養サンプルの準備に用いる場合、培養時間は必ずしも必要ではない。そのため、培養時間のセルが省略されていてもよい。検査リスト220は、各カウント表を識別するための識別情報として一次元シンボルや二次元シンボルなどの識別画像221を付与されていてもよい。識別画像221は、ユーザの識別情報を含んでいてもよい。
FIG. 27 shows the test list 220. The MCU 30 may output the inspection list 220 from the printer 38 or may output it to the display device of the terminal device 1c. The inspection list 220 is a list created from the corresponding count table 55. The order in which the information is arranged in the count table 55 and the order in which the information is arranged in the test list 220 may be different or may match. The test list 220 may be the same as the count table 55 displayed on the display device 37. Furthermore, since there is no need to write count results in the test list 220, cells for writing count results may be omitted. Furthermore, if the user uses the test list 220 to prepare a culture sample, the culture time is not necessarily required. Therefore, cells for culture time may be omitted. The inspection list 220 may be provided with an identification image 221 such as a one-dimensional symbol or a two-dimensional symbol as identification information for identifying each count table. The identification image 221 may include user identification information.
図26に示されたボタン214が押されると、MCU30は、ヘッド装置1aにフロントカメラ10の起動を指示する。ヘッド装置1aのMCU20は、フロントカメラ10を起動し、識別画像221の読み取りを試行する。識別画像221は単にシンボルと呼ばれてもよい。この際にユーザは、フロントカメラ10に識別画像221を読み取らせるよう、検査リスト220の位置をフロントカメラ10に対して合わせる。MCU20は、識別画像221の読取に成功すると、識別画像221から識別情報を復号(デコード)して、PC1bへ送信する。MCU30は、ヘッド装置1aから受信された識別情報に関連付けられているカウント表を記憶装置35から読み出す。
When the button 214 shown in FIG. 26 is pressed, the MCU 30 instructs the head device 1a to start the front camera 10. The MCU 20 of the head device 1a starts the front camera 10 and attempts to read the identification image 221. Identification image 221 may simply be called a symbol. At this time, the user positions the inspection list 220 with respect to the front camera 10 so that the front camera 10 reads the identification image 221. When the MCU 20 successfully reads the identification image 221, it decodes the identification information from the identification image 221 and transmits it to the PC 1b. The MCU 30 reads the count table associated with the identification information received from the head device 1a from the storage device 35.
図28は、ユーザが身に着けるユーザ認証札230を示している。データインテグリティ規制のために、ヘッド装置1aを使用するユーザに種々の制限が課されることがある。たとえば、米国のFDA(食品医薬品局)の規則である21 CFR Part11によれば、ユーザは、物理的および論理的に管理されることが求められている。たとえば、ヘッド装置1aおよびPC1bについてもユーザごとに使用可能な機能を制限するために、ユーザ認証札230が利用されてもよい。ユーザは、フロントカメラ10によりユーザ認証札230の識別画像221を読み取らせることで、MCU20またはMCU30がユーザ認証を実行してもよい。つまり、識別画像221は、ユーザ名とパスワードなどのアカウント情報を示すシンボルを含んでいてもよい。ただし、ユーザ名とパスワードは暗号化された上で、識別画像221となっている。
FIG. 28 shows a user authentication tag 230 worn by the user. Due to data integrity regulations, various restrictions may be imposed on users who use the head device 1a. For example, according to 21 CFR Part 11, which is a regulation of the US FDA (Food and Drug Administration), users are required to be managed physically and logically. For example, the user authentication tag 230 may be used to limit the functions that can be used for each user in the head device 1a and the PC 1b. The MCU 20 or MCU 30 may perform user authentication by having the user read the identification image 221 of the user authentication tag 230 with the front camera 10. That is, the identification image 221 may include symbols indicating account information such as a user name and password. However, the user name and password are encrypted and become the identification image 221.
ユーザごとの機能制限としては、次のようなものが考えられる。一例として、ユーザは、管理者、リーダー、および作業者に分かれている。管理者は、ユーザを追加したり、各ユーザの権限を設定したりすることができる。リーダーは、カウント表を作成でき、カウントを実行でき、カウント結果を保存でき、カウント結果を編集でき、カウント結果を出力(印刷、送信)できる。作業者は、カウントを実行でき、カウント結果を保存できる。MCU20およびMCU30は、識別画像221から特定されたユーザの権限に応じて、そのユーザが実行できる機能を制限してもよい。
Possible functional limitations for each user include the following: As an example, users are divided into administrators, leaders, and workers. The administrator can add users and set permissions for each user. The reader can create a counting table, perform counting, save the counting results, edit the counting results, and output (print, send) the counting results. Workers can perform counting and save the counting results. The MCU 20 and the MCU 30 may limit the functions that the user can perform, depending on the authority of the user identified from the identification image 221.
こ
こで、フロントカメラ10により識別画像221が読み取られているが、メインカメラ11により識別画像221が読み取られてもよい。 Although the identification image 221 is read by the front camera 10 here, the identification image 221 may also be read by the main camera 11.
こで、フロントカメラ10により識別画像221が読み取られているが、メインカメラ11により識別画像221が読み取られてもよい。 Although the identification image 221 is read by the front camera 10 here, the identification image 221 may also be read by the main camera 11.
図41が示すように、フロントカメラ10およびメインカメラ11は、シャーレ15に貼付されたシール270に印刷されているシャーレ番号や識別画像221を撮像して読み取ってもよい。識別画像221には、カウント表55の識別情報、サンプル名、カウント結果が格納されるセルを示す固有の識別情報などが符号化されていてもよい。つまり、識別画像221を読み取ることで、MCU30は、カウント表55、サンプル名、シャーレ15、検査条件を特定することができる。さらに、MCU30は、特定された検査条件をヘッド装置1aに送信し、ヘッド装置1aのMCU20は受信された検査条件にしたがってメインカメラ11、リング照明装置12、13、および同軸照明装置14を制御し、画像を取得できる。
As shown in FIG. 41, the front camera 10 and the main camera 11 may image and read the petri dish number and identification image 221 printed on a sticker 270 attached to the petri dish 15. The identification image 221 may be encoded with identification information of the count table 55, a sample name, unique identification information indicating a cell in which the count result is stored, and the like. That is, by reading the identification image 221, the MCU 30 can specify the count table 55, sample name, petri dish 15, and test conditions. Furthermore, the MCU 30 transmits the specified inspection conditions to the head device 1a, and the MCU 20 of the head device 1a controls the main camera 11, ring illumination devices 12, 13, and coaxial illumination device 14 according to the received inspection conditions. , images can be obtained.
[フロントカメラの他の応用例] (1)セルへのテキスト入力 図29はボタン54を押すことで備考として利用される新規の列が追加されたカウント表55を示している。新規の列は、自由列として定義されており、文字や数字だけでなく、画像などを保持することができる。
[Other Application Examples of Front Camera] (1) Text Input to Cell FIG. 29 shows a count table 55 to which a new column to be used as a note is added by pressing the button 54. The new column is defined as a free column and can hold not only letters and numbers but also images.
図30は、自由列のセルをポインタ57で右クリックされると表示される編集画面240を示している。この例では、セルに対するテキスト「商品番号:」が入力済みであり、それに続くテキストを入力するためのダイアログ241が表示されている。ダイアログ241は、編集画面240のテキストボックス内をポインタ57で右クリックすることで表示される。ダイアログ241は、フロントカメラ10を利用することで商品等からコードを読み取り、読取結果をセルに入力するための複数の選択肢を含む。この例では、選択肢として、フロントカメラ10によるコードの読み取りが含まれる。たとえば、「コード読み取り(一次元シンボル)」がポインタ57により選択され、読み取りボタン242が押されると、MCU30は、ヘッド装置1aに対して一次元シンボルの読み取りを指示する。
FIG. 30 shows an edit screen 240 that is displayed when a cell in a free column is right-clicked with the pointer 57. In this example, the text "product number:" has already been entered in the cell, and a dialog 241 for entering the following text is displayed. The dialog 241 is displayed by right-clicking inside the text box on the editing screen 240 with the pointer 57. The dialog 241 includes a plurality of options for reading a code from a product or the like using the front camera 10 and inputting the reading result into a cell. In this example, the options include reading the code using the front camera 10. For example, when "code reading (one-dimensional symbol)" is selected by the pointer 57 and the read button 242 is pressed, the MCU 30 instructs the head device 1a to read the one-dimensional symbol.
図31は、読み取りボタン242が押されると、表示装置37に表示される読取画面250を示している。チェックボックス251は、MCU20がコードの認識に成功したときにMCU30が読取画面250を自動的に閉じることを指示するためのチェックボックスである。画像領域252は、フロントカメラ10により取得された動画像または静止画像を表示する。読取結果領域253は、一次元シンボルや二次元シンボルから復号されたテキストを表示する領域である。
FIG. 31 shows a reading screen 250 displayed on the display device 37 when the reading button 242 is pressed. The check box 251 is a check box for instructing the MCU 30 to automatically close the reading screen 250 when the MCU 20 successfully recognizes the code. The image area 252 displays a moving image or a still image captured by the front camera 10. The reading result area 253 is an area that displays text decoded from one-dimensional symbols and two-dimensional symbols.
ヘッド装置1aのMCU20はフロントカメラ10を起動し、一次元コードを読み取らせ、一次元コードからテキストを復号し、復号されたテキストをPC1bへ送信する。ユーザは読取結果領域253に表示されたテキストを確認し、OKボタン254またはキャンセルボタン255を押す。OKボタン254が押されると、MCU30は、読取画面250を閉じて編集画面240に戻り、ヘッド装置1aから受信されたテキストをセルに挿入する。キャンセルボタン255が押されると、ヘッド装置1aから受信されたテキストを破棄し、読取画面250を閉じて、編集画面240に戻る。
The MCU 20 of the head device 1a activates the front camera 10, causes it to read the one-dimensional code, decodes text from the one-dimensional code, and transmits the decoded text to the PC 1b. The user confirms the text displayed in the reading result area 253 and presses the OK button 254 or cancel button 255. When the OK button 254 is pressed, the MCU 30 closes the reading screen 250, returns to the editing screen 240, and inserts the text received from the head device 1a into the cell. When the cancel button 255 is pressed, the text received from the head device 1a is discarded, the reading screen 250 is closed, and the screen returns to the editing screen 240.
図32は、テキストを挿入された編集画面240を示す。ここで、OKボタン254が押されると、MCU30は、編集画面240を閉じ、図29に示されたUI50を表示装置37に表示する。
FIG. 32 shows the edit screen 240 with text inserted. Here, when the OK button 254 is pressed, the MCU 30 closes the editing screen 240 and displays the UI 50 shown in FIG. 29 on the display device 37.
(2)セルへの画像入力 図33は、カウント表の一部、またはカウント表から作成されたカウントレポート260の一例を示している。カウント表55に含まれる自由列のセルには画像データを関連付けることができる。MCU30は、ヘッド装置1aのメインカメラ11を制御してシャーレ15の画像(シャーレ画像)を取得し、取得したシャーレ画像をセルに関連付ける。あるいは、MCU30は、ヘッド装置1aのフロントカメラ10を制御してシャーレ15の画像(シャーレ画像)を取得し、取得したシャーレ画像をセルに関連付けてもよい。同様に、MCU30は、ヘッド装置1aのフロントカメラ10を制御して商品の外観画像を取得し、取得した外観画像をセルに関連付けてもよい。さらに、MCU30は、ヘッド装置1aのフロントカメラ10を制御して商品に付与されているバーコードを読み取って復号させ、復号された商品番号等をセルに入力してもよい。MCU30は、プリンタ38を制御し、カウントレポート260を紙に印刷してもよい。
(2) Image input to cells FIG. 33 shows an example of a part of a count table or a count report 260 created from the count table. Image data can be associated with cells in free columns included in the count table 55. The MCU 30 controls the main camera 11 of the head device 1a to obtain an image of the petri dish 15 (petri dish image), and associates the obtained petri dish image with a cell.

[Flowchart] (1) Main processes of PC1b FIG. 34 is a flowchart showing a series of processes executed by the MCU 30 of PC1b. The MCU 30 executes the following processing according to the count application program stored in the storage device 35.
S1でMCU30はカウント表の編集を実行する。図5から図15などを用いて説明されたように、UI50などを通じてカウント表が編集または作成される。
In S1, the MCU 30 edits the count table. As explained using FIGS. 5 to 15 and the like, the count table is edited or created through the UI 50 and the like.
S2でMCU30はカウント表を記憶装置35に保存する。
In S2, the MCU 30 stores the count table in the storage device 35.

In S3, the MCU 30 identifies the count table. Identification of the count table may be performed using the front camera 10 and the inspection list 220 or the user authentication tag 230, or may be performed using the file UI 200 shown in FIG. 26.
S4でMCU30は特定されたカウント表を記憶装置35から読み出す。これにより、図16に示されたUI100が表示装置37に表示される。
In S4, the MCU 30 reads the specified count table from the storage device 35. As a result, the UI 100 shown in FIG. 16 is displayed on the display device 37.

In S5, the MCU 30 specifies the cell to which the count value is written. Initially, a cell in the top row of the count table may be selected, or a cell clicked by the pointer 57 may be selected.
S6でMCU30はアクティブセルに関連付けられている検査条件を特定する。たとえば、MCU30は、カウント表の作成の際に各セルに対し関連付けられた検査条件を記憶装置35から読み出す。
In S6, the MCU 30 specifies test conditions associated with the active cell. For example, the MCU 30 reads the inspection conditions associated with each cell from the storage device 35 when creating the count table.
S7でMCU30は、アクティブセルに関連付けられている検査条件をヘッド装置1aに設定する。上述されたように、メインカメラ11の感度、点灯すべき照明装置、明るさ、点灯すべき発光素子の数(照射方向)、画像処理(HDR、リング除去)、カウントアルゴリズム(閾値などのパラメータ)などをヘッド装置1aに送信する。
In S7, the MCU 30 sets the inspection conditions associated with the active cell in the head device 1a. As described above, the sensitivity of the main camera 11, the lighting device to be lit, the brightness, the number of light emitting elements to be lit (irradiation direction), image processing (HDR, ring removal), counting algorithm (parameters such as threshold) etc. are sent to the head device 1a.
S8でMCU30は検査条件が変更されたかどうかを判定する。上述されたように、セルに関連付けられた検査条件は検査中においても随時変更可能である。よって、検査条件が変更されると、MCU30は、S7に戻り、変更後の検査条件をヘッド装置1aに送信する。検査条件が変更されていなければ、MCU30は、S9に進む。
In S8, the MCU 30 determines whether the inspection conditions have been changed. As described above, the test conditions associated with a cell can be changed at any time even during testing. Therefore, when the inspection conditions are changed, the MCU 30 returns to S7 and transmits the changed inspection conditions to the head device 1a. If the inspection conditions have not been changed, the MCU 30 proceeds to S9.
S9でMCU30は、ユーザにより撮影指示が入力されたかどうかを判定する。ユーザは、ヘッド装置1aの第一ハードウエアボタン8aまたはUI100の第一ソフトウエアボタン105aを押すことで撮影を指示することができる。撮影指示が入力されていなければ、MCU30はS9からS8に戻る。撮影指示が入力されると、MCU30は、S9からS10に進む。
In S9, the MCU 30 determines whether a shooting instruction has been input by the user. The user can instruct photography by pressing the first hardware button 8a of the head device 1a or the first software button 105a of the UI 100. If no photographing instruction has been input, the MCU 30 returns from S9 to S8. When the shooting instruction is input, the MCU 30 proceeds from S9 to S10.
S10でMCU30は、ヘッド装置1aに対して撮像指示を送信する。
In S10, the MCU 30 transmits an imaging instruction to the head device 1a.
S11でMCU30は、ヘッド装置1aからメインカメラ11により取得されたシャーレ画像103の画像(検査画像)を取得し、UI100の結果領域102に検査画像を表示する。
In S11, the MCU 30 acquires an image (inspection image) of the petri dish image 103 acquired by the main camera 11 from the head device 1a, and displays the inspection image in the result area 102 of the UI 100.

The user can input a count instruction by pressing the first hardware button 8a of the head device 1a or the first software button 105a of the UI 100, which is assigned as a count button. If no count instruction has been input, the MCU 30 returns to S8 from S12. When the count instruction is input, the MCU 30 proceeds from S12 to S13.
S13でMCU30は、カウント指示をヘッド装置1aへ送信する。なお、カウント処理がPC1bにより実行される場合、MCU30がMCU20の代わりにカウント処理を実行する。
In S13, the MCU 30 transmits a count instruction to the head device 1a. Note that when the counting process is executed by the PC 1b, the MCU 30 executes the counting process instead of the MCU 20.
S14でMCU30は、ヘッド装置1aからカウント結果を受信し、カウント結果をカウント値領域104に表示する。なお、S14でMCU30がカウント処理を実行する場合、MCU30はカウント処理を実行することで得られたカウント結果をカウント値領域104に表示する。
In S14, the MCU 30 receives the count result from the head device 1a and displays the count result in the count value area 104. Note that when the MCU 30 executes the counting process in S14, the MCU 30 displays the count result obtained by executing the counting process in the count value area 104.
S15で、MCU30は、画像処理、カウントアルゴリズム等の検査条件が変更されたかどうかを判定する。検査条件が変更されると、S13に戻る。検査条件が変更されていなければ、MCU30はS16に進む。なお、S8の検査条件の変更は画像の再取得が必要になるような検査条件の変更が想定されている。S15の検査条件の変更は取得された画像に対する画像処理の変更をもたらすが、画像の再取得は不要なものが想定されている。
In S15, the MCU 30 determines whether inspection conditions such as image processing and counting algorithm have been changed. When the inspection conditions are changed, the process returns to S13. If the inspection conditions have not been changed, the MCU 30 proceeds to S16. It should be noted that the change in the inspection conditions in S8 is assumed to be a change in the inspection conditions that would require reacquisition of the image. Although the change in inspection conditions in S15 results in a change in image processing for the acquired image, it is assumed that re-acquisition of the image is unnecessary.
S16でMCU30は、ユーザにより登録指示が入力されたかどうかを判定する。ユーザは、登録ボタンとして割当たられたヘッド装置1aの第二ハードウエアボタン8bまたはUI100の第二ソフトウエアボタン105bを押すことで、登録指示を入力できる。登録指示が入力されていなければ、MCU30は、S16からS8に戻り、撮りなおしを実行したり、検査条件を変更したりする。登録指示が入力されると、MCU30は、S16からS17に進む。
In S16, the MCU 30 determines whether a registration instruction has been input by the user. The user can input a registration instruction by pressing the second hardware button 8b of the head device 1a or the second software button 105b of the UI 100, which is assigned as a registration button. If no registration instruction has been input, the MCU 30 returns from S16 to S8, and retakes the image or changes the inspection conditions. When the registration instruction is input, the MCU 30 proceeds from S16 to S17.
S17でMCU30は、カウント結果をアクティブセルに登録する。
In S17, the MCU 30 registers the count result in the active cell.
S18でMCU30は、カウントがすべて終了したかどうかを判定する。たとえば、カウント表に存在するすべてのセルにカウント結果が入力されていれば、MCU30は、カウント終了と判定する。まだ、未入力のセルが存在している場合、MCU30は、S18からS5に進み、アクティブセルを次のセルに変更する(セルの特定)。
In S18, the MCU 30 determines whether all counts have been completed. For example, if count results have been input to all cells in the count table, the MCU 30 determines that counting has ended. If there are still uninput cells, the MCU 30 proceeds from S18 to S5 and changes the active cell to the next cell (cell identification).
(2)ヘッド装置1aの主な処理 図35は、ヘッド装置1aのMCU20が制御プログラムにしたがって実行する一連の処理を示す。
(2) Main processes of the head device 1a FIG. 35 shows a series of processes executed by the MCU 20 of the head device 1a according to the control program.

In S21, the MCU 20 determines whether or not an instruction for photographing the front camera 10 has been received. When reading the identification image 221 of the inspection list 220 as described above, an instruction for photographing the front camera 10 (instruction to read a code) is input from the PC 1b to the head device 1a. If no photographing instruction for the front camera 10 has been input, the MCU 20 proceeds from S21 to S23.

In S25, the MCU 20 determines whether an instruction to change the test conditions has been received from the PC 1b. Change instructions are received along with new test conditions. When the instruction to change the test conditions is received, the MCU 20 returns to S24 and sets new test conditions. If the change instruction has not been received, the MCU 20 proceeds from S25 to S26.
S26でMCU20は、PC1bから撮像指示が受信されたかどうかを判定する。撮像指示が入力されていなければ、MCU20は、S26からS25に戻る。撮像指示が入力されると、MCU20は、S26からS27に進む。

(3)サンプルデータベースの登録 カウント表は複数の行および列を有し、さらに各セルには検査条件が関連付けられている。カウント表や検査リストは、日ごとに作り替えられることがある。ただし、同一のサンプルについて毎日検査が実行されることもある。したがって、検査頻度の多いサンプルについては、サンプルDB40に予め登録しておくことで、カウント表の作成処理の負担が軽減される。そこで、サンプル表を作成したときに、ユーザは、各サンプルに対応する行要素をサンプルDB40に登録してもよい。
(3) Registration of sample database The count table has multiple rows and columns, and each cell is associated with an inspection condition. Count tables and inspection lists may be revised daily. However, tests may be performed on the same sample every day. Therefore, by registering samples that are frequently tested in the sample DB 40 in advance, the burden of creating a count table can be reduced. Therefore, when creating a sample table, the user may register row elements corresponding to each sample in the sample DB 40.
図36は、PC1bのMCU30により実行されるサンプルDB40の編集処理を示すフローチャートである。MCU30は、記憶装置35に記憶されたアプリケーションプログラム39にしたがって以下の処理を実行する。
FIG. 36 is a flowchart showing the sample DB 40 editing process executed by the MCU 30 of the PC 1b. The MCU 30 executes the following processing according to the application program 39 stored in the storage device 35.
S41でMCU30は、カウント表に含まれる複数の行要素のうちサンプルDB40に登録したい行要素の選択を受け付ける。たとえば、MCU30は、サンプル表に含まれる行要素のうちいずれかの行要素に対するポインタ57によるクリックを受け付けてもよい。
In S41, the MCU 30 accepts selection of a row element desired to be registered in the sample DB 40 from among a plurality of row elements included in the count table. For example, the MCU 30 may accept a click by the pointer 57 on any of the row elements included in the sample table.
S42でMCU30は、選択された行要素の追加指示を受け付ける。たとえば、行要素が選択された状態でポインタ57により右クリックが実行されると、追加指示が入力されてもよい。
In S42, the MCU 30 receives an instruction to add the selected row element. For example, when a right click is performed with the pointer 57 while a row element is selected, an additional instruction may be input.
S43でMCU30は、追加指示された行要素のサンプル名を取得し、同一のサンプル名がすでにサンプルDB40に登録済みであるかどうかを判定する(重複判定)。追加指示された行要素が既に存在しなければ、MCU30は、S43からS45に進む。追加指示された行要素がサンプルDB40に存在すれば、MCU30は、S43からS44に進む。
In S43, the MCU 30 acquires the sample name of the row element for which addition has been instructed, and determines whether the same sample name has already been registered in the sample DB 40 (duplication determination). If the row element specified to be added does not already exist, the MCU 30 proceeds from S43 to S45. If the row element specified to be added exists in the sample DB 40, the MCU 30 proceeds from S43 to S44.
S44でMCU30は、サンプルDB40に行要素を上書きするかどうかをユーザに問い合わせる。キャンセル指示が入力されると、MCU30は、行要素の追加をキャンセルする。上書き指示が入力されると、MCU30は、S44からS45に進む。
In S44, the MCU 30 asks the user whether to overwrite the row element in the sample DB 40. When the cancel instruction is input, the MCU 30 cancels the addition of the row element. When the overwrite instruction is input, the MCU 30 proceeds from S44 to S45.

(4) Count table editing FIG. 37 is a flowchart showing the count table editing process executed by the MCU 30 of the PC 1b. The MCU 30 executes the following processing according to the count application program stored in the storage device 35.
S51でMCU30は、カウント表において新しく行要素を追加される位置(セルまたは行)を特定する。たとえば、MCU30は、カウント表においてサンプル名が入力済みである最終行の次の行を選択する。なお、ある行と別の行との間に新たな行が選択されてもよい。たとえば、カウント表においてサンプル名が入力済みである行が選択され、ポインタ57による右クリックが実行されると、選択された行の次に空行が追加される。
In S51, the MCU 30 identifies a position (cell or row) in the count table where a new row element is to be added. For example, the MCU 30 selects the next row after the last row in which the sample name has been input in the count table. Note that a new row may be selected between a certain row and another row. For example, when a row in which a sample name has already been input is selected in the count table and a right click is performed using the pointer 57, a blank row is added next to the selected row.
S52でMCU30は、サンプルDB40から行の追加が指示されたかどうかを判定する。たとえば、UI50のボタン64が押されると、MCU30は、サンプルDB40から行の追加が指示されたと認識する。サンプルDB40から行の追加が指示されると、MCU30は、S53に進む。サンプルDB40から行の追加が指示されていなければ、MCU30は、S61に進む。
In S52, the MCU 30 determines whether an instruction to add a row has been given from the sample DB 40. For example, when the button 64 on the UI 50 is pressed, the MCU 30 recognizes that the sample DB 40 has instructed to add a row. When the sample DB 40 instructs to add a row, the MCU 30 proceeds to S53. If there is no instruction to add a row from the sample DB 40, the MCU 30 proceeds to S61.
S53でMCU30は、追加指示された行の項目名をサンプルDB40から取得する。
In S53, the MCU 30 acquires the item name of the line for which addition has been instructed from the sample DB 40.

In S54, the MCU 30 acquires the inspection conditions of the row for which addition has been instructed from the sample DB 40.
S55でMCU30は、取得された項目名と検査条件とをカウント表に貼り付ける。つまり、MCU30は新規の行要素をカウント表に追加する。なお、MCU30は、サンプルDB40に保持されている複数の行要素のうちユーザにより指定された行要素が新規のカウント表に含まれているか否かを判定してもよい。さらに、ユーザにより指定された行要素が新規のカウント表に含まれていないと判定された場合、MCU30は、ユーザにより指定された行要素が新規のカウント表に含まれていない列要素のセルを含むか否かを判定してもよい。ユーザにより指定された行要素が新規のカウント表に含まれていない列要素のセルを含むと判定された場合、MCU30は、当該列要素を新規のカウント表に追加する。つまり、すでにカウント表に存在する他のサンプル名を付与された行要素にも列要素が追加されることになる。
In S55, the MCU 30 pastes the acquired item names and inspection conditions onto the count table. That is, the MCU 30 adds a new row element to the count table. Note that the MCU 30 may determine whether a row element specified by the user among the plurality of row elements held in the sample DB 40 is included in the new count table. Further, if it is determined that the row element specified by the user is not included in the new count table, the MCU 30 selects a column element cell whose row element specified by the user is not included in the new count table. It may be determined whether or not it is included. If it is determined that the row element specified by the user includes a cell of a column element that is not included in the new count table, the MCU 30 adds the column element to the new count table. In other words, column elements are added to row elements that are already in the count table and are given other sample names.
S56でMCU30は、編集完了かどうかを判定する。ユーザにより編集完了が指示されると、MCU30は、カウント表を記憶装置35に保存する。ユーザにより編集完了が指示されなければ、MCU30は、S56からS51に戻る。
In S56, the MCU 30 determines whether editing is complete. When the user instructs to complete the editing, the MCU 30 stores the count table in the storage device 35. If editing completion is not instructed by the user, the MCU 30 returns to S51 from S56.
サンプルDB40を利用せずに新規に行が追加される場合、S61でMCU30は、キーボード32やポインティングデバイス33を通じた項目名の入力を受け付ける。

[ハレーション(光沢)低減] コロニーに対して照明光を照射すると、コロニーにハレーションが発生することがある。ハレーションが発生すると、画素値が飽和してしまうため、その画素の情報が失われてしまう。その結果、コロニーのカウント値に誤差が生じてしまうことがある。特に、コロニーの色に基づきコロニーの種別を分類することは困難となる。また、培地の種別によってはハレーションが生じやすいことがある。そこで、本実施例では、ハレーションの影響を低減することでコロニーの計数精度を向上させる。
[Reducing halation (glossy)] When illuminating a colony with illumination light, halation may occur in the colony. When halation occurs, the pixel value becomes saturated and information about that pixel is lost. As a result, errors may occur in colony count values. In particular, it is difficult to classify the type of colony based on the color of the colony. Further, depending on the type of medium, halation may easily occur. Therefore, in this embodiment, colony counting accuracy is improved by reducing the influence of halation.
図42は、ハレーションの一例を示す図である。培地にも様々なものがあるが、最も多いものはシャーレ15に入れられた液体状の培地である。図42の左側が示すように、シャーレ15に対して全方向から一様に照明光を照射すると、コロニーの輪郭にハレーション(リング)が発生することがある。図42が示すようなフィルム状の培地ではフィルムの表面に
生じる起伏によってハレーションが発生することがある。そこで、本実施例では、ハレーションを低減するための処理(以下、光沢低減処理)が採用される。これにより、図42の右側の画像が示すように、ハレーションが低減される。 FIG. 42 is a diagram showing an example of halation. There are various types of culture medium, but the most common one is a liquid culture medium placed in a petri dish 15. As shown on the left side of FIG. 42, when the petri dish 15 is uniformly irradiated with illumination light from all directions, halation (ring) may occur on the outline of the colony. In a film-like culture medium as shown in FIG. 42, halation may occur due to undulations occurring on the surface of the film. Therefore, in this embodiment, a process for reducing halation (hereinafter referred to as gloss reduction process) is adopted. This reduces halation, as shown in the image on the right side of FIG. 42.

図43は、リング照明装置12、13における複数の発光素子12aの配置を示している。この例では、基板400上に32個の発光素子12aが円環状に並べられている。MCU20は、32個の発光素子12aのうち、任意の個数の発光素子12aを点灯させることができる。
FIG. 43 shows the arrangement of the plurality of light emitting elements 12a in the ring illumination devices 12 and 13. In this example, 32 light emitting elements 12a are arranged in an annular shape on the substrate 400. The MCU 20 can light up any number of light emitting elements 12a among the 32 light emitting elements 12a.
図44は、四つの照明方向i~ivを実現するための点灯パターンを示している。点灯パターンiは、図44において上方に位置する8個の発光素子12aを点灯させるパターンである。点灯パターンiiは、図44において右方に位置する8個の発光素子12aを点灯させるパターンである。点灯パターンiiiは、図44において下方に位置する8個の発光素子12aを点灯させるパターンである。点灯パターンivは、図44において左方に位置する8個の発光素子12aを点灯させるパターンである。これらの点灯パターンは一例にすぎない。たとえば、32個の発光素子12aのうち連続して配置された4個の発光素子12aを順番に点灯させることで、8個の照明方向を実現することができる。32個の発光素子12aをすべて点灯させることで、全方向照明が実現される。なお、明るさを半分に低減するために、一つ置きに発光素子12aが点灯されてもよい。
FIG. 44 shows lighting patterns for realizing four lighting directions i to iv. The lighting pattern i is a pattern in which the eight light emitting elements 12a located above in FIG. 44 are lit. The lighting pattern ii is a pattern in which eight light emitting elements 12a located on the right side in FIG. 44 are lit. Lighting pattern iii is a pattern in which eight light emitting elements 12a located at the bottom in FIG. 44 are lit. The lighting pattern iv is a pattern in which eight light emitting elements 12a located on the left side in FIG. 44 are lit. These lighting patterns are just examples. For example, by sequentially lighting up four consecutively arranged light emitting elements 12a among the 32 light emitting elements 12a, eight illumination directions can be realized. Omnidirectional illumination is realized by lighting all 32 light emitting elements 12a. Note that in order to reduce the brightness by half, the light emitting elements 12a may be turned on every other light emitting element 12a.
図45は、光沢低減処理の一例を説明する図である。この例で、画像データ401aは、照明方向iから検査個体を照明することでメインカメラ11により取得された画像データである。画像データ401bは、照明方向iiから検査個体を照明することでメインカメラ11により取得された画像データである。画像データ401cは、照明方向iiiから検査個体を照明することでメインカメラ11により取得された画像データである。画像データ401dは、照明方向ivから検査個体を照明することでメインカメラ11により取得された画像データである。
FIG. 45 is a diagram illustrating an example of gloss reduction processing. In this example, the image data 401a is image data acquired by the main camera 11 by illuminating the inspection object from the illumination direction i. The image data 401b is image data acquired by the main camera 11 by illuminating the inspection object from the illumination direction ii. The image data 401c is image data acquired by the main camera 11 by illuminating the inspection object from the illumination direction iii. The image data 401d is image data acquired by the main camera 11 by illuminating the inspection object from the illumination direction iv.
MCU20またはMCU30は、四つの画像データ401aないし画像データ401dを合成することで、光沢低減画像402を作成し、光沢低減画像402におけるコロニーをカウントする。
The MCU 20 or MCU 30 creates a reduced gloss image 402 by combining the four image data 401a to 401d, and counts colonies in the reduced gloss image 402.
たとえば、MCU20またはMCU30は、四つの画像データ401aないし画像データ401dにおいて同一の座標に位置する画素を注目画素として順番に選択する。座標がx,yであるとすると、画像データ401aにおける注目画素Pa(x,y)、画像データ401bにおける注目画素Pb(x,y)、画像データ401cにおける注目画素Pc(x,y)、および、画像データ401dにおける注目画素Pd(x,y)が抽出される。このうちで、ハレーションを起こしている画素は、合成に用いられない。たとえば、Pa(x,y)が飽和しているが、Pb(x,y)、Pc(x,y)、およびPd(x,y)が飽和していなかった場合、光沢低減画像における注目画素Pp(x,y)は、以下のように算出される。Pp(x,y)=(Pb(x,y)+Pc(x,y)+Pd(x,y))/3 ・・・(1)これを光沢低減画像402におけるすべての座標(画素)について順番に実行することで、光沢低減画像402が生成される。
For example, the MCU 20 or MCU 30 sequentially selects pixels located at the same coordinates in the four image data 401a to 401d as the pixel of interest. Assuming that the coordinates are x, y, the pixel of interest Pa (x, y) in the image data 401a, the pixel of interest Pb (x, y) in the image data 401b, the pixel of interest Pc (x, y) in the image data 401c, and , the pixel of interest Pd(x,y) in the image data 401d is extracted. Among these pixels, pixels causing halation are not used for composition. For example, if Pa (x, y) is saturated but Pb (x, y), Pc (x, y), and Pd (x, y) are not saturated, the pixel of interest in the gloss-reduced image Pp(x,y) is calculated as follows. Pp (x, y) = (Pb (x, y) + Pc (x, y) + Pd (x, y)) / 3 ... (1) This is done in order for all coordinates (pixels) in the reduced gloss image 402 By executing this, a reduced gloss image 402 is generated.
ハレーションなどの光沢を低減することで次のようなメリットが得られる。(1)コロニーの色が明確となる。これにより、MCU20、30は、複数のコロニー(菌種)を色で区別することが可能となる。これにより、菌種ごとのコロニーの計数精度が向上する。(2)コロニーを上方(メインカメラ11側)から見たときの形状(二次元形状、輪郭)が明確となる。MCU20、30は、検査画像(光沢低減画像)を二値化してからコロニーを計数することがある。この場合、コロニーの輪郭が明確になると、コロニーの計数精度が向上する。(3)光沢をもつコロニーと光沢を持たないコロニーとを分類することが可能となる。MCU20、30は、全方向照明画像から光沢をもつコロニーをカウントし、光沢低減画像から光沢を持たないコロニーをカウントできる。つまり、光沢をもつコロニーと光沢を持たないコロニーとを分類することが可能となる。なお、MCU20、30は、四つの画像データ401aないし画像データ401dを加算合成することで、全方向照明画像を生成してもよい。
The following benefits can be obtained by reducing gloss such as halation. (1) The color of the colony becomes clear. This allows the MCUs 20 and 30 to distinguish between multiple colonies (bacterial species) by color. This improves the accuracy of counting colonies for each bacterial species. (2) The shape (two-dimensional shape, outline) when the colony is viewed from above (main camera 11 side) becomes clear. The MCUs 20 and 30 may count colonies after binarizing the inspection image (reduced gloss image). In this case, when the outline of the colony becomes clearer, the accuracy of counting the colonies improves. (3) It becomes possible to classify colonies with gloss and colonies without gloss. The MCUs 20 and 30 can count colonies with gloss from the omnidirectional illumination image and count colonies without gloss from the reduced gloss image. In other words, it is possible to classify colonies with gloss and colonies without gloss. Note that the MCUs 20 and 30 may generate the omnidirectional illumination image by adding and combining the four image data 401a to 401d.
また、MCU20、30は、光沢低減画像においてコロニーが存在する画素領域(コロニー領域)を二値化し、二値化された領域と、全方向照明画像(光沢非低減画像)における対応する領域とを重畳し、コロニー領域上にどの程度の比率で光沢が存在するかを表示してもよい。また、MCU20、30は、コロニー領域における光沢領域の割合(比率)を演算してもよい。MCU20、30は、光沢比率が閾値を超えていれば、コロニー領域を光沢コロニーと分類してもよい。MCU20、30は、光沢比率が閾値以下であれば、コロニー領域を非光沢コロニーと分類してもよい。なお、コロニーが光沢を有する場合、コロニーが高さ方向に成長していることを意味する。つまり、MCU20、30は、高さ方向に成長したコロニーをカウントすることができる。
Furthermore, the MCUs 20 and 30 binarize the pixel area where a colony exists (colony area) in the gloss-reduced image, and compare the binarized area and the corresponding area in the omnidirectional illumination image (non-glossy-reduced image). They may be superimposed and the ratio of gloss present on the colony area may be displayed. Furthermore, the MCUs 20 and 30 may calculate the proportion (ratio) of the glossy area in the colony area. The MCUs 20 and 30 may classify the colony area as a gloss colony if the gloss ratio exceeds the threshold value. The MCUs 20 and 30 may classify the colony area as a non-glossy colony if the gloss ratio is less than or equal to the threshold value. Note that when the colony is shiny, it means that the colony is growing in the height direction. That is, the MCUs 20 and 30 can count colonies that have grown in the height direction.
図46は、光沢低減画像に対して光沢非低減画像を重畳して生成した画像を示す。実線の矩形は、非光沢コロニーを示す。破線は、光沢コロニーを示す。このように、MCU20、30は、高さ方向に成長したコロニーを発見することができる。
FIG. 46 shows an image generated by superimposing a non-glossy image on a glossy-reduced image. Solid rectangles indicate non-glossy colonies. Dashed lines indicate shiny colonies. In this way, the MCUs 20 and 30 can discover colonies that have grown in the height direction.
図47は、カウント設定UI410を示している。カウント設定UI410は、培地の種別を選択するためのメニュー411を有している。メニュー411は、菌種分類評価を含む。MCU30は、菌種分類評価が選択されると、ユーザの追加の指示を待たずに、チェックボックス420にチェックを入れて、リング除去(光沢低減処理)を有効化してもよい。ユーザはポインタ57を操作してチェックボックス420をオン(チェック)/オフ(非チェック)できる。ユーザがポインタ57を操作してチェックボックス420からチェックを外した場合、MCU30は、光沢低減処理(光沢低減モード)を無効化し、光沢非低減処理(光沢非低減モード)を有効化する。このように、MCU30は、培地の種別に応じて、光沢低減モードまたは光沢非低減モードを選択してもよい。
FIG. 47 shows the count setting UI 410. The count setting UI 410 has a menu 411 for selecting the type of medium. Menu 411 includes bacterial species classification evaluation. When the bacterial species classification evaluation is selected, the MCU 30 may check the check box 420 to enable ring removal (glossy reduction processing) without waiting for additional instructions from the user. The user can turn on (check)/off (uncheck) the check box 420 by operating the pointer 57. When the user operates the pointer 57 to uncheck the checkbox 420, the MCU 30 disables the gloss reduction process (glossy reduction mode) and enables the non-glossy reduction process (non-glossy reduction mode). In this way, the MCU 30 may select the gloss reduction mode or the non-glossy reduction mode depending on the type of medium.
チェックボックス420がチェックされると、MCU30は、暫定的に光沢低減モードに移行してもよい。MCU30は、リング照明装置12に点灯パターンiを設定し、メインカメラ11に検査個体を撮影させ、画像データ401aを取得する。MCU30は、リング照明装置12に点灯パターンiiを設定し、メインカメラ11に検査個体を撮影させ、画像データ401bを取得する。MCU30は、リング照明装置12に点灯パターンiiiを設定し、メインカメラ11に検査個体を撮影させ、画像データ401cを取得する。MCU30は、リング照明装置12に点灯パターンivを設定し、メインカメラ11に検査個体を撮影させ、画像データ401dを取得する。MCU30は、画像データ401a~401dを合成して光沢低減画像402を生成し、結果領域102に表示する。
When check box 420 is checked, MCU 30 may temporarily shift to gloss reduction mode. The MCU 30 sets a lighting pattern i on the ring lighting device 12, causes the main camera 11 to photograph the specimen to be inspected, and obtains image data 401a. The MCU 30 sets the lighting pattern ii on the ring illumination device 12, causes the main camera 11 to photograph the specimen to be inspected, and acquires image data 401b. The MCU 30 sets the lighting pattern iii on the ring illumination device 12, causes the main camera 11 to photograph the specimen to be inspected, and acquires image data 401c. The MCU 30 sets a lighting pattern iv on the ring illumination device 12, causes the main camera 11 to photograph the specimen to be inspected, and obtains image data 401d. The MCU 30 synthesizes the image data 401a to 401d to generate a reduced gloss image 402, and displays it in the result area 102.
光沢低減画像402は、ユーザの明示的な指示を待たずに生成されてもよい。この場合の光沢低減画像402は、ユーザに対して光沢低減処理の有効化を推奨することになろう。ユーザは、低減処理の効果に納得すれば、チェックボックス420をチェックした状態に維持するだろう。一方、ユーザは、低減処理の効果に納得しなければ、チェックボックス420からチェックを外すことになるだろう。この場合、MCU30は、リング照明装置12に全方向照明コマンドを送信し、検査個体に全方向照明を適用し、メインカメラ11に撮影を実行させ、全方向照明画像を取得し、結果領域102に表示する。
The reduced gloss image 402 may be generated without waiting for explicit instructions from the user. In this case, the gloss reduction image 402 would recommend enabling the gloss reduction process to the user. If the user is satisfied with the effect of the reduction process, he or she will keep the check box 420 checked. On the other hand, if the user is not satisfied with the effect of the reduction process, he or she will likely uncheck the checkbox 420. In this case, the MCU 30 sends an omnidirectional illumination command to the ring illumination device 12 , applies omnidirectional illumination to the test specimen, causes the main camera 11 to take an image, acquires an omnidirectional illumination image, and displays the result area 102 as an omnidirectional illumination image. indicate.
分類結果領域430は、各分類ごとに計数されたコロニーの個数を表示する。分類Iは光沢を有するコロニーである。分類IIは黄色のコロニーである。分類IIIは、その他のコロニーである。ここで示された分類は一例にすぎない。
The classification result area 430 displays the number of colonies counted for each classification. Class I is a shiny colony. Category II is yellow colonies. Class III is other colonies. The classification shown here is only an example.
図48が示すように、MCU30は、全方向照明画像である光沢非低減画像403と、光沢低減画像402とを結果領域102において並べて表示してもよい。これにより、ユーザは、光沢低減処理の効果を簡単に確認することができるであろう。
As shown in FIG. 48, the MCU 30 may display the non-glossy image 403, which is an omnidirectional illumination image, and the reduced gloss image 402 side by side in the result area 102. This will allow the user to easily confirm the effect of the gloss reduction process.
[光沢低減処理に関するフローチャート] 図49は、光沢低減処理を含むコロニーカウント方法を示すフローチャートである。ここでは、各ステップがMCU30により実行されるものとして説明されるが、一部またはすべてのステップがMCU20により実行されてもよい。
[Flowchart related to gloss reduction processing] FIG. 49 is a flowchart showing a colony counting method including gloss reduction processing. Although each step is described here as being executed by the MCU 30, some or all of the steps may be executed by the MCU 20.
S101でMCU30は、培地の種別の入力を受け付ける。たとえば、ユーザはポインティングデバイス33を操作してカウント設定UI410におけるメニュー411から培地の種別を入力する。培地の種別は、たとえば、フィルム状培地などであってもよい。
In S101, the MCU 30 receives input of the type of medium. For example, the user operates the pointing device 33 to input the type of culture medium from the menu 411 in the count setting UI 410. The type of medium may be, for example, a film-like medium.
S102でMCU30は、第一ソフトウエアボタン105a(第一ハードウエアボタン8a)などにより撮影指示が入力されたかどうかを判定する。撮影指示が入力されると、MCU30はS102からS103に進む。
In S102, the MCU 30 determines whether a shooting instruction has been input using the first software button 105a (first hardware button 8a) or the like. When the photographing instruction is input, the MCU 30 proceeds from S102 to S103.
S103でMCU30は、ユーザにより指定または選択された培地の種別に基づき、光沢低減が必要かどうかを判定する。なお、MCU30は、培地の種別を考慮せずに、ユーザによる明示的な指示(例:チェックボックス420)の有無に基づき、光沢低減が必要かどうかを判定してもよい。記憶装置35は、培地の種別と光沢低減の有無とを関連付けた判定テーブルを記憶していてもよい。この場合、MCU30は判定テーブルを参照し、培地の種別に関連付けられている光沢低減の有無(光沢低減モード/光沢非低減モード)を取得する。光沢低減が不要であれば、MCU30は、S110に進み、全方向照明で検査個体の撮影を実行する。MCU30は、MCU20から全方向照明画像403を取得し、記憶装置35に格納する。一方で、光沢低減が必要であれば、MCU30は、S104に進む。
In S103, the MCU 30 determines whether gloss reduction is necessary based on the type of medium specified or selected by the user. Note that the MCU 30 may determine whether gloss reduction is necessary based on the presence or absence of an explicit instruction by the user (eg, check box 420), without considering the type of medium. The storage device 35 may store a determination table that associates the type of culture medium with the presence or absence of gloss reduction. In this case, the MCU 30 refers to the determination table and obtains the presence or absence of gloss reduction (glossy reduction mode/non-glossy reduction mode) associated with the type of culture medium. If gloss reduction is not necessary, the MCU 30 proceeds to S110 and executes photographing of the test individual using omnidirectional illumination. The MCU 30 acquires the omnidirectional illumination image 403 from the MCU 20 and stores it in the storage device 35. On the other hand, if gloss reduction is necessary, the MCU 30 proceeds to S104.
S104でMCU30は、ヘッド装置1aに照明コマンドを送信し、リング照明装置12の照明方向を設定する。たとえば、照明コマンドにより点灯パターンi~ivが順番にヘッド装置1aに設定される。MCU20は、照明コマンドにより指定された点灯パターンでリング照明装置12を点灯させる。
In S104, the MCU 30 transmits a lighting command to the head device 1a and sets the lighting direction of the ring lighting device 12. For example, lighting patterns i to iv are sequentially set in the head device 1a by a lighting command. The MCU 20 lights the ring lighting device 12 in a lighting pattern specified by the lighting command.
S105でMCU30は、撮影コマンドをヘッド装置1aに送信し、指定された照明方向から照明された検査個体について撮影を実行する。MCU20は、撮影コマンドを受信し、撮影コマンドにしたがって検査個体を撮影して画像データを生成し、MCU30へ送信する。MCU30は、MCU20から画像データを取得し、記憶装置35に格納する。
In S105, the MCU 30 transmits a photographing command to the head device 1a, and executes photographing of the test individual illuminated from the specified illumination direction. The MCU 20 receives the photographing command, photographs the specimen to be inspected according to the photographing command, generates image data, and transmits the image data to the MCU 30 . The MCU 30 acquires image data from the MCU 20 and stores it in the storage device 35.
S106でMCU30は、撮影数は十分かどうかを判定する。たとえば、四つの画像データ401aから401dが必要な場合、MCU30は、四つの画像データ401aから401dがすべて取得されたかどうかを判定する。撮影数が十分でなければ、MCU30は、S104に戻り、ヘッド装置1aに次の照明方向を設定する。これにより、照明方向が変更される。一方で、撮影数が十分であれば、MCU30は、S107に進む。
In S106, the MCU 30 determines whether the number of shots is sufficient. For example, if four image data 401a to 401d are required, the MCU 30 determines whether all four image data 401a to 401d have been acquired. If the number of shots is not sufficient, the MCU 30 returns to S104 and sets the next illumination direction on the head device 1a. This changes the illumination direction. On the other hand, if the number of shots is sufficient, the MCU 30 proceeds to S107.
S107でMCU30は、記憶装置35から画像データ401aないし401dを読み出して合成し、光沢低減画像402を生成する。
In S107, the MCU 30 reads the image data 401a to 401d from the storage device 35 and combines them to generate the reduced gloss image 402.
S108でMCU30は、検査画像(光沢低減画像402または全方向照明画像403)からコロニーをカウントする。
In S108, the MCU 30 counts colonies from the inspection image (the reduced gloss image 402 or the omnidirectional illumination image 403).
図50は、コロニーの分類方法を示すフローチャートである。ここでは、各ステップがMCU30により実行されるものとして説明されるが、一部またはすべてのステップがMCU20により実行されてもよい。
FIG. 50 is a flowchart showing a colony classification method. Although each step is described here as being executed by the MCU 30, some or all of the steps may be executed by the MCU 20.
S111でMCU30は、全方向照明(標準照明)
で検査個体の撮影を実行する。たとえば、MCU30は、全方向照明コマンドをヘッド装置1aに送信するとともに、撮影コマンドをヘッド装置1aに送信する。MCU20は、全方向照明コマンドを受信すると、リング照明装置12に含まれる32個の発光素子12aを同時に点灯し、すべての照明方向から照明光を検査個体に照射する。また、MCU20は、撮影コマンドを受信すると、メインカメラ11に検査個体を撮影させて画像データを生成し、画像データ(全方向照明画像403)をMCU30へ送信する。これにより全方向照明画像403が取得される。なお、それぞれ照明方向が異なる複数の画像データ401aないし401dから擬似的に全方向照明画像403が生成される場合、S111は省略される。 In S111, MCU30 has omnidirectional illumination (standard illumination)
Execute photographing of the test specimen. For example, the MCU 30 transmits an omnidirectional illumination command to the head device 1a, and also transmits a photographing command to the head device 1a. When the MCU 20 receives the omnidirectional illumination command, it simultaneously lights up the 32 light emitting elements 12a included in the ring illumination device 12, and irradiates the test object with illumination light from all illumination directions. Further, upon receiving the photographing command, the MCU 20 causes the main camera 11 to photograph the specimen to be inspected, generates image data, and transmits the image data (omnidirectional illumination image 403) to the MCU 30. As a result, an omnidirectional illumination image 403 is obtained. Note that when the omnidirectional illumination image 403 is generated in a pseudo manner from a plurality of image data 401a to 401d each having a different illumination direction, S111 is omitted.

Note that when the omnidirectional illumination image 403 is generated in a pseudo manner from a plurality of image data 401a to 401d each having a different illumination direction, S111 is omitted.
S112でMCU30は、光沢低減画像402の撮影を実行する。たとえば、MCU30は、図49に示されたS104からS107を実行する。
In S112, the MCU 30 executes shooting of the reduced gloss image 402. For example, the MCU 30 executes S104 to S107 shown in FIG. 49.
S113でMCU30は、光沢低減画像402でコロニーをカウントする。これにより、コロニーを形成している画素群(領域)が特定される。MCU30は、記憶装置35に、コロニーの位置を示す位置情報(どの画素がコロニーであるかを示す情報)を格納する。
In S113, the MCU 30 counts colonies in the reduced gloss image 402. As a result, the pixel group (region) forming the colony is specified. The MCU 30 stores position information indicating the position of a colony (information indicating which pixel is a colony) in the storage device 35.
S114でMCU30は、記憶装置35に記憶されているコロニー領域の位置情報を参照し、一つのコロニー領域を選択する。
In S114, the MCU 30 refers to the position information of the colony areas stored in the storage device 35 and selects one colony area.
S115(オプション)でMCU30は、全方向照明画像403でコロニー領域のヒストグラムを作成する。たとえば、MCU30は、選択されたコロニー領域を構成している複数の画素の座標を記憶装置35から読み出し、読み出された座標に対応する画素の画素値を全方向照明画像403から取得する。全方向照明画像403は、光沢低減処理を適用されていない。そのため、注目画素が光沢画素であれば、注目画素は高輝度の画素である。MCU30は、全方向照明画像403において、複数の画素の画素値に基づき光沢のヒストグラムを作成してもよい。
In S115 (optional), the MCU 30 creates a histogram of the colony area using the omnidirectional illumination image 403. For example, the MCU 30 reads the coordinates of a plurality of pixels constituting the selected colony area from the storage device 35, and acquires the pixel value of the pixel corresponding to the read coordinates from the omnidirectional illumination image 403. Omnidirectional illumination image 403 has no gloss reduction processing applied to it. Therefore, if the pixel of interest is a glossy pixel, the pixel of interest is a high-luminance pixel. The MCU 30 may create a gloss histogram based on the pixel values of a plurality of pixels in the omnidirectional illumination image 403.
S116でMCU30は、コロニー領域内で光沢領域が占める割合(比率)を求める。たとえば、MCU30は、コロニー領域に含まれる画素の総数で、光沢領域に含まれる画素の総数を除算することで、比率を演算してもよい。
In S116, the MCU 30 determines the proportion (ratio) occupied by the glossy area within the colony area. For example, the MCU 30 may calculate the ratio by dividing the total number of pixels included in the glossy area by the total number of pixels included in the colony area.
S117でMCU30は、コロニー領域内で光沢領域が占める割合が所定の閾値を超えているかどうかを判定する。割合が所定の閾値を超えていれば、MCU30は、S118に進み、コロニー領域を光沢コロニーに分類する。一方で、割合が所定の閾値以下であれば、MCU30は、S120に進み、コロニー領域を非光沢コロニーに分類する。
In S117, the MCU 30 determines whether the proportion of the glossy area within the colony area exceeds a predetermined threshold. If the ratio exceeds the predetermined threshold, the MCU 30 proceeds to S118 and classifies the colony area as a glossy colony. On the other hand, if the ratio is below the predetermined threshold, the MCU 30 proceeds to S120 and classifies the colony area as a non-glossy colony.
S119でMCU30は、すべてのコロニー領域の分類が完了したかどうかを判定する。分類されていないコロニー領域が残っている場合、MCU30は、S114に戻り、次のコロニー領域を選択する。これにより、次のコロニー領域について分類が実行される。一方で、すべてのコロニー領域が分類されていれば、MCU30は、コロニーの分類方法を終了する。
In S119, the MCU 30 determines whether classification of all colony areas has been completed. If unclassified colony areas remain, the MCU 30 returns to S114 and selects the next colony area. As a result, classification is performed for the next colony area. On the other hand, if all colony areas have been classified, the MCU 30 ends the colony classification method.
図47が示すように、MCU30は、各分類の種類または名称と、各分類ごとのコロニーの個数とを分類結果領域430に表示してもよい。これにより、ユーザは、分類ごとのカウント数を容易に確認することができるようになろう。
As shown in FIG. 47, the MCU 30 may display the type or name of each classification and the number of colonies for each classification in the classification result area 430. With this, the user will be able to easily check the count number for each category.
<まとめ> [観点A1] 記憶装置35は、複数の検査個体の各々のカウント結果が入力されるセルを含むカウント表を記憶する記憶部の一例である。MCU30および表示制御部36は、記憶部に記憶されているカウント表を表示装置37に表示する表示制御部の一例である。MCU30およびポインティングデバイス33などは、表示制御部により表示されるカウント表に含まれる複数のセルの中から、カウント結果が入力される対象セルを特定するセル特定部の一例である。MCU20またはMCU30は、ユーザの操作にしたがった計数指示を生成する計数指示部の一例である。MCU30およびメインカメラ11は、計数指示部で生成された計数指示に基づいて検査個体の画像である検査画像を取得する取得部の一例である。MCU20またはMCU30は、取得部で取得された検査画像に基づき検査個体に含まれるコロニーを計数する計数部の一例である。図19や図20などが例示するように、MCU20またはMCU30は、計数部により計数されたコロニーの数を対象セルに反映する表管理部として機能する。これにより、コロニーの計数結果についての事後処理に関するユーザの負担が軽減される。
<Summary> [Aspect A1] The storage device 35 is an example of a storage unit that stores a count table including cells into which the count results of each of a plurality of test individuals are input. The MCU 30 and the display control unit 36 are examples of a display control unit that displays the count table stored in the storage unit on the display device 37. The MCU 30, the pointing device 33, and the like are examples of a cell specifying section that specifies a target cell into which a count result is input from among a plurality of cells included in the count table displayed by the display control section. MCU20 or MCU30 is an example of a counting instruction unit that generates counting instructions according to user operations. The MCU 30 and the main camera 11 are an example of an acquisition unit that acquires an inspection image, which is an image of an individual to be inspected, based on the counting instruction generated by the counting instruction unit. The MCU 20 or MCU 30 is an example of a counting unit that counts colonies included in the test individual based on the test image acquired by the acquisition unit. As illustrated in FIGS. 19 and 20, the MCU 20 or 30 functions as a table management unit that reflects the number of colonies counted by the counting unit in the target cell. This reduces the burden on the user regarding post-processing of colony counting results.
[観点A2] 表管理部(例:MCU30)は、ユーザ操作に応じて検査個体の識別情報を格納する識別情報セルと、識別情報セルと関連付けられ、検査個体についてのコロニーの数のカウント結果を格納するカウント結果セルと、を含むカウント表を作成し、記憶部に当該カウント表を記憶させてもよい。つまり、図5や図16などが示すように、カウント表55、82は、検査個体の識別情報(例:サンプル名)を格納する識別情報セルと、識別情報セルと関連付けられ、検査個体についてのコロニーの数のカウント結果を格納するカウント結果セルと、を含んでもよい。これにより、ユーザは、カウント表を手書きで作成する手間を省くことができるであろう。
[Viewpoint A2] The table management unit (e.g. MCU 30) is associated with an identification information cell that stores identification information of a test individual according to a user operation, and a count result of the number of colonies for the test individual. A count table including count result cells to be stored may be created and the count table may be stored in the storage unit. In other words, as shown in FIGS. 5 and 16, the count tables 55 and 82 are associated with identification information cells that store identification information (e.g. sample name) of the tested individual, and with the identification information cells, A count result cell storing a count result of the number of colonies may be included. This will save the user the trouble of creating a count table by hand.
[観点A3] 表管理部(例:MCU30)は、コロニーの数のカウント結果を格納するカウント結果セルに対して検査条件を関連付けてもよい。これにより、カウント結果が格納されるセルに対して検査条件を関連付けておくことで、コロニーに関する検査を事項する際に検査条件を容易に設定することが可能となる。
[Aspect A3] The table management unit (eg, MCU 30) may associate test conditions with count result cells that store the count results of the number of colonies. By associating test conditions with cells in which count results are stored, test conditions can be easily set when testing colonies.
[観点A4] 取得部は、検査個体を照明する照明部(例:リング照明装置12、13、同軸照明装置14)と、照明部により照明された検査個体を撮像する撮像部(例:メインカメラ11)と、を有してもよい。検査条件は、照明部の照明条件(例:照明の種類、明るさ)を含んでもよい。大腸菌、一般生菌などの菌の種別や培地の種別(例:シート型の培地、液体型の培地、選択型の培地)に応じて適切な照明条件は異なる。よって、検査条件として照明条件を含めることで、各セルに適した照明条件が設定可能となる。さらに、検査条件は、撮像部の撮像条件(例:露光時間)を含んでもよい。培地の色やコロニーの色によって適切な撮像条件は異なりうる。検査条件が撮像条件を含むことで、各セルごとに適切な撮像条件が設定可能となろう。
[Viewpoint A4] The acquisition unit includes an illumination unit that illuminates the inspection object (e.g. ring illumination devices 12, 13, coaxial illumination device 14), and an imaging unit that images the inspection object illuminated by the illumination unit (e.g. main camera). 11). The inspection conditions may include lighting conditions of the lighting section (eg, type of lighting, brightness). Appropriate lighting conditions differ depending on the type of bacteria, such as Escherichia coli or general viable bacteria, and the type of medium (e.g., sheet type medium, liquid type medium, selective type medium). Therefore, by including illumination conditions as inspection conditions, illumination conditions suitable for each cell can be set. Furthermore, the inspection conditions may include imaging conditions (eg, exposure time) of the imaging unit. Appropriate imaging conditions may vary depending on the color of the medium and the color of the colony. By including the imaging conditions in the inspection conditions, it will be possible to set appropriate imaging conditions for each cell.
[観点A5] 照明部は、検査個体を落射照明する第一照明モード(例:リング照明装置12を点灯するモード)と、撮像部に対して対向する方向から検査個体を透過照明する第二照明モード(例:同軸照明装置14を点灯するモード)とのいずれかにしたがって動作してもよい。検査条件は、第一照明モードまたは第二照明モードの選択を含む。検査条件が照明モードの指定を含むことで、各セルごとに適切な照明モードを選択することが可能となろう。
[Viewpoint A5] The illumination unit has a first illumination mode that epi-illuminates the inspected individual (e.g. a mode that lights up the ring illumination device 12), and a second illumination mode that transmits and illuminates the inspected individual from the direction opposite to the imaging unit. mode (eg, a mode in which the coaxial lighting device 14 is turned on). The inspection conditions include selection of the first illumination mode or the second illumination mode. If the inspection conditions include the designation of the illumination mode, it will be possible to select an appropriate illumination mode for each cell.
[観点A6] 検査条件は、計数部に適用される計数条件を含んでもよい。ここで、計数条件は、コロニーを検出するための閾値、および、コロニーを検出する際の基準となる色の少なくとも一方を含みうる。たとえば、計数条件は、コロニーとそれ以外とを区別するための閾値(例:検出感度を左右する二値化閾値)、および、コロニーを計数する際の基準となる色(例:前景色、背景色)を含んでもよい。MCU20またはMCU30は、検査画像を二値化してコロニーの個数をカウントしてもよい。よって、二値化閾値はコロニーの検出感度を左右する。二値化閾値を適切に設定することで、コロニーの誤検出が減少する。また、コロニーの色と培地の色とを適切に設定することが出来れば、コロニーの誤検出が減少する。各セルごとに計数条件を設定することで、各セルごとにコロニーの誤検出が減少するであろう。また、計数条件に応じて計数アルゴリズムを適切に調整することが可能となろう。
[Aspect A6] The inspection conditions may include counting conditions applied to the counting section. Here, the counting conditions may include at least one of a threshold value for detecting colonies and a color serving as a reference when detecting colonies. For example, the counting conditions include a threshold value for distinguishing between colonies and others (e.g., a binarization threshold that affects detection sensitivity), and a color (e.g., foreground color, background color) that is the standard for counting colonies. color). MCU20 or MCU30 may binarize the inspection image and count the number of colonies. Therefore, the binarization threshold affects the colony detection sensitivity. By appropriately setting the binarization threshold, false detection of colonies is reduced. Furthermore, if the color of the colony and the color of the medium can be appropriately set, false detection of colonies will be reduced. Setting counting conditions for each cell will reduce false detection of colonies for each cell. Furthermore, it will be possible to appropriately adjust the counting algorithm depending on the counting conditions.
[観点A7] 計数部(例:MCU20、MCU30)は、ユーザにより計数指示が入力されると、対象セルに関連付けられている検査条件にしたがった照明コマンドを照明部に出力してもよい。照明部は、照明コマンドにしたがって検査個体を照明する。撮像部は、照明コマンドにしたがって照明部により照明された検査個体を撮像して検査画像を生成する。計数部は、照明コマンドが反映された検査画像に基づきコロニーの数を計数する。これにより、各セルごとに設定された検査条件が反映された検査画像についてコロニー数を計数することが可能となる。
[Aspect A7] When a counting instruction is input by the user, the counting unit (eg, MCU 20, MCU 30) may output an illumination command according to the inspection condition associated with the target cell to the illumination unit. The illumination unit illuminates the inspection object according to the illumination command. The imaging unit generates an inspection image by capturing an image of the inspection object illuminated by the illumination unit according to the illumination command. The counting unit counts the number of colonies based on the inspection image in which the illumination command is reflected. This makes it possible to count the number of colonies in an inspection image that reflects the inspection conditions set for each cell.
[観点A8] 計数部(例:MCU20、MCU30)は、特定部により対象セルが第一セルから第二セルに変更されると、取得部に適用される検査条件を、第一セルに関連付けられている第一検査条件から、第二セルに関連付けられている第二検査条件に変更する。このように、対象セルが変更されるとそれに連動して検査条件を変更することが可能となる。各セルごとに、つまり、検査個体ごとに適切な検査条件はことなることがある。予めセルごとに適切な検査条件が設定されていれば、ユーザはセルを選択するだけで適切な検査条件を選択することが可能となろう。
[Viewpoint A8] When the target cell is changed from the first cell to the second cell by the specific unit, the counting unit (e.g. MCU20, MCU30) changes the inspection condition applied to the acquisition unit to be associated with the first cell. The first test condition associated with the second cell is changed to the second test condition associated with the second cell. In this way, when the target cell is changed, the inspection conditions can be changed in conjunction with the change. Appropriate test conditions may vary for each cell, that is, for each individual to be tested. If appropriate inspection conditions are set for each cell in advance, the user will be able to select appropriate inspection conditions simply by selecting a cell.
[観点A9] サンプルDB40は、カウント表55,82の作成を補助するためのデータベースである。MCU30は、データベースにデータを登録する登録部として機能してもよい。カウント表55、82は、識別情報セルとカウント結果セルとをそれぞれ含む複数の行要素を有してもよい。登録部(MCU30)は、カウント結果がカウント結果セルに入力されたカウント表82に含まれる行要素をデータベースに登録するように構成されてもよい。ここで、行要素は、セルと当該セルに関連付けられた検査条件とを含む。表管理部(MCU30)は、データベースに保持されている複数の行要素のうちユーザにより指定された行要素に基づき新規のカウント表を作成してもよい。たとえば、ユーザにより指定された行要素を構成するセルと当該セルに関連付けられている検査条件とが新規のカウント表へコピーされる。また、セルに格納されていたカウント結果は、サンプルDB40に登録される際に削除されてもよい。このように、予めカウント表の行要素として採用可能な行要素をデータベース化しておくことで、ユーザは、新規のカウント表を容易に作成することができる。
[Viewpoint A9] The sample DB 40 is a database for assisting the creation of the count tables 55 and 82. The MCU 30 may function as a registration unit that registers data in a database. The count tables 55 and 82 may have a plurality of row elements each including an identification information cell and a count result cell. The registration unit (MCU 30) may be configured to register row elements included in the count table 82 whose count results are input into count result cells in the database. Here, the row element includes a cell and a test condition associated with the cell. The table management unit (MCU 30) may create a new count table based on a row element specified by the user among a plurality of row elements held in the database. For example, cells constituting a row element specified by the user and inspection conditions associated with the cells are copied to a new count table. Further, the count result stored in the cell may be deleted when being registered in the sample DB 40. In this way, by creating a database of row elements that can be adopted as row elements of a count table in advance, the user can easily create a new count table.
[観点A10] カウント表55、82は、複数の列要素を有してもよい。複数の列要素は、それぞれ組み合わせに関連付けられていてもよい。ここで、組み合わせとは、検査個体の培養条件(例:希釈倍率、培養時間)と菌種(例:一般生菌、大腸菌)との組み合わせである。各列要素は、培養条件と菌種との組み合わせが異なっている。たとえば、第一列要素と第二列要素とでは、培養条件と菌種とのうち少なくとも一方が異なっている。これにより、ある検査個体について、様々な培養条件と様々な菌種とから構成される複数の組み合わせそれぞれ対応するセルを一行にまとめることも可能となろう。
[Viewpoint A10] The count tables 55 and 82 may have multiple column elements. Each of the plurality of column elements may be associated with a combination. Here, the combination is a combination of the culture conditions (eg, dilution ratio, culture time) of the test individual and the bacterial species (eg, common viable bacteria, Escherichia coli). Each column element has a different combination of culture conditions and bacterial species. For example, the first row element and the second row element are different in at least one of culture conditions and bacterial species. This would make it possible to group cells corresponding to a plurality of combinations of various culture conditions and various bacterial species into one row for a certain test individual.
[観点A11] 表管理部(例:MCU30)は、データベースに保持されている複数の行要素のうちユーザにより指定された行要素(指定行要素)が、新規のカウント表に含まれているか否かを判定してもよい。指定行要素がカウント表に含まれていないと判定された場合、MCU30は、指定行要素が、カウント表に含まれていない新規の列要素のセルを含むか否かを判定してもよい。指定行要素が新規の列要素のセルを含むと判定された場合、MCU30は、当該新規の列要素を新規のカウント表に追加する。一方、指定行要素がカウント表にすでに含まれているか、または、指定行要素が新規の列要素のセルを含まない場合、当該列要素はカウント表に追加されない。これにより、テーブル表における行要素の重複と列要素の重複が抑制され、テーブル表のコンパクト化が実現されよう。
[Viewpoint A11] The table management unit (e.g. MCU 30) determines whether the row element specified by the user (designated row element) among the multiple row elements held in the database is included in the new count table. It may be determined whether If it is determined that the designated row element is not included in the count table, the MCU 30 may determine whether the designated row element includes a cell of a new column element that is not included in the count table. If it is determined that the designated row element includes a cell of a new column element, the MCU 30 adds the new column element to a new count table. On the other hand, if the specified row element is already included in the count table, or if the specified row element does not include a cell of a new column element, the column element is not added to the count table. As a result, duplication of row elements and duplication of column elements in the table will be suppressed, and the table will be made more compact.
[観点A12、13] データベースは、親子関係を定義された複数の行要素を含んでもよい。親子関係は、完成品を親とし、当該完成品を構成する具材を子とする関係であ
ってもよい。商品全体(完成品)の培養結果におけるコロニーのカウントと、商品を構成する個別の具材の培養結果におけるコロニーのカウントとが必要なケースがある。よって、親子関係をあらかじめ定義しておくことで、カウント表を作成する際のユーザ工数が削減される。たとえば、ある完成品(例:サンドイッチ)が選択されたときに、その具材(例:ハム、レタス)が選択可能に提示されてもよい。 [Aspects A12, 13] The database may include a plurality of row elements in which a parent-child relationship is defined. The parent-child relationship may be such that the finished product is the parent and the ingredients constituting the finished product are the children. There are cases where it is necessary to count colonies in the culture results of the entire product (finished product) and to count colonies in the culture results of individual ingredients that make up the product. Therefore, by defining the parent-child relationship in advance, the user's man-hours when creating a count table can be reduced. For example, when a certain finished product (eg, sandwich) is selected, its ingredients (eg, ham, lettuce) may be presented for selection.

For example, when a certain finished product (eg, sandwich) is selected, its ingredients (eg, ham, lettuce) may be presented for selection.
[観点A14] 表管理部(例:MCU30)は、親子関係を定義された複数の行要素を一括して新規のカウント表に追加してもよい。これにより、カウント表を作成する際のユーザの負担がさらに軽減されるであろう。
[Aspect A14] The table management unit (eg, MCU 30) may add a plurality of row elements with defined parent-child relationships to a new count table all at once. This will further reduce the burden on the user when creating the count table.
[観点A15] 表管理部(例:MCU30)は、統計処理の適用が指示されると、同一の検査個体をそれぞれ培養するn個の培養器の各カウント結果を格納するn個の行要素と、当該n個の行要素の統計処理結果を格納する少なくとも1個の行要素と、を含むようにカウント表を作成してもよい。図11によれば、n=2の事例が説明されている。nは3以上であってもよい。これにより、平均化等の統計処理を実行するカウント表の作成が容易になろう。
[Viewpoint A15] When the table management unit (e.g. MCU 30) is instructed to apply statistical processing, it creates n row elements that store the count results of n incubators each cultivating the same test individual. , and at least one row element that stores the statistical processing results of the n row elements. According to FIG. 11, the case of n=2 is illustrated. n may be 3 or more. This will make it easier to create a count table for performing statistical processing such as averaging.
[観点A16] 図16などが例示するように、表示制御部(例:MCU30)は、表示装置37に、検査画像とカウント表とを並べて(同時並行的に)表示させてもよい。セル特定部(例:MCU30)は、表示装置37に検査画像とともに表示されるカウント表に含まれる複数のセルの中から、ユーザの選択にしたがって対象セルを特定してもよい。表示制御部(例:MCU30)は、計数部により計数されたコロニーの数が対象セルに反映されたカウント表を、検査画像とともに表示装置に表示させてもよい。これにより、カウント結果を格納されるセルが容易に選択可能となろう。
[Viewpoint A16] As illustrated in FIG. 16 and the like, the display control unit (eg, MCU 30) may display the inspection image and the count table side by side (simultaneously in parallel) on the display device 37. The cell specifying unit (eg, MCU 30) may specify a target cell from among a plurality of cells included in the count table displayed together with the inspection image on the display device 37 according to the user's selection. The display control unit (eg, MCU 30) may cause the display device to display a count table in which the number of colonies counted by the counting unit is reflected in the target cell together with the inspection image. This will make it easier to select the cell in which the count result is stored.
[観点A17] 図25が例示するように、表示制御部(例:MCU30)は、対象セルに関連付けられる検査条件に含まれる照明条件を設定するための第一コントロールオブジェクト(例:タブ123)と、当該検査条件に含まれる計数条件を設定するための第二コントロールオブジェクト(例:タブ124)と、を表示装置37に表示してもよい。これにより、セルに関連付けられている検査条件を容易に変更することが可能となろう。さらに、表示制御部(例:MCU30)は、第一コントロールオブジェクト(例:タブ123)に対するユーザ操作を検知すると、照明条件を設定するための設定画面(例:確認画面110)を表示装置に表示してもよい。表示制御部(例:MCU30)は、第二コントロールオブジェクト(例:タブ124)に対するユーザ操作を検知すると、計数条件を設定するための設定画面(例:設定画面120)を表示装置に表示してもよい。
[Viewpoint A17] As illustrated in FIG. 25, the display control unit (e.g. MCU 30) has a first control object (e.g. tab 123) for setting the illumination conditions included in the inspection conditions associated with the target cell. , and a second control object (eg, tab 124) for setting counting conditions included in the inspection conditions may be displayed on the display device 37. This would make it possible to easily change the test conditions associated with a cell. Furthermore, when the display control unit (e.g., MCU 30) detects a user operation on the first control object (e.g., tab 123), the display control unit (e.g., MCU 30) displays a setting screen (e.g., confirmation screen 110) for setting lighting conditions on the display device. You may. When the display control unit (e.g., MCU 30) detects a user operation on the second control object (e.g., tab 124), the display control unit (e.g., MCU 30) displays a setting screen (e.g., setting screen 120) for setting counting conditions on the display device. Good too.
[観点A18] 表示制御部(例:MCU30)は、計数部に計数を指示するための第三コントロールオブジェクト(例:第一ソフトウエアボタン105a)と、カウント結果を対象セルに登録することを指示するための第四コントロールオブジェクト(例:第二ソフトウエアボタン105b)と、を表示装置37に表示してもよい。これによりユーザは容易にカウントの指示とカウント結果の登録とを指示することが可能となろう。
[Viewpoint A18] The display control unit (e.g. MCU 30) provides a third control object (e.g. first software button 105a) for instructing the counting unit to count and for instructing to register the count result in the target cell. A fourth control object (e.g., second software button 105b) for doing so may be displayed on the display device 37. This will enable the user to easily instruct counting and registration of count results.
[観点A19] 表示制御部(例:MCU30)は、第三コントロールオブジェクトに対するユーザ操作を検知すると、当該第三コントロールオブジェクトを、計数を指示するためのコントロールオブジェクト(例:カウントボタン)から、取得部に検査画像の取得を指示するためのコントロールオブジェクト(例:撮影ボタン、撮りなおしボタン)に割り当ててもよい。つまり、MCU30は、第三コントロールオブジェクトを操作することで発行されるコマンドを、計数を指示するためのコマンドから、検査画像の取得を指示するためのコマンドに変更してもよい。これにより、操作可能なボタンの数が削減され、ユーザは、今、何を操作すべきかを容易に判断できるであろう。
[Viewpoint A19] When the display control unit (e.g. MCU 30) detects a user operation on the third control object, the display control unit (e.g. MCU 30) converts the third control object from the control object (e.g. count button) for instructing counting to the acquisition unit. It may be assigned to a control object (eg, a shooting button, a reshooting button) for instructing the acquisition of an inspection image. That is, the MCU 30 may change the command issued by operating the third control object from a command for instructing counting to a command for instructing acquisition of a test image. This reduces the number of operable buttons, allowing the user to easily determine what to operate now.
[観点A20] 図18が例示するように、表示制御部(例:MCU30)は、第三コントロールオブジェクトが計数を指示するためのコントロールオブジェクト(例:カウントボタン)に割り当てられているときは、ユーザ操作を受け付けないように第四コントロールオブジェクト(例:登録ボタン)を表示してもよい。図19が例示すように、計数を指示するためのコントロールオブジェクトに割り当てられている第三コントロールオブジェクトが操作されると、計数結果が取得される。表示制御部(例:MCU30)は、計数結果が取得されると、第三コントロールオブジェクトが取得部に検査画像の取得を指示するためのコントロールオブジェクト(例:撮影ボタン)に割り当てられ、かつ、ユーザ操作を受け付けるように第四コントロールオブジェクト(例:登録ボタン)を変更してもよい。つまり、第三コントロールオブジェクトに対して計数を指示するためのコマンドが割り当てられているときは、ユーザ操作を受け付けないように第四コントロールオブジェクトが表示されてもよい。さらに、計数を指示するためのコマンドが割り当てられている第三コントロールオブジェクトが操作されて、カウント結果が取得されると、第三コントロールオブジェクトに対して、取得部に検査画像の取得を指示するためのコマンドが割り当てられ、かつ、ユーザ操作を受け付けるように、第四コントロールオブジェクトの表示が変更されてもよい。これにより、ユーザは、今、何を操作すべきかを容易に判断できるであろう。
[Viewpoint A20] As illustrated in FIG. 18, when the third control object is assigned to a control object (e.g. count button) for instructing counting, the display control unit (e.g. MCU 30) A fourth control object (eg, registration button) may be displayed so as not to accept operations. As illustrated in FIG. 19, when the third control object assigned to the control object for instructing counting is operated, a counting result is obtained. The display control unit (e.g., MCU 30) assigns a third control object to a control object (e.g., shooting button) for instructing the acquisition unit to acquire an inspection image when the counting result is acquired, and The fourth control object (eg, registration button) may be changed to accept an operation. That is, when a command for instructing counting is assigned to the third control object, the fourth control object may be displayed so as not to accept user operations. Furthermore, when the third control object to which a command for instructing counting is assigned is operated and the count result is obtained, the third control object is configured to instruct the obtaining unit to obtain the inspection image. The display of the fourth control object may be changed so that the command is assigned to the fourth control object and accepts a user operation. This will allow the user to easily determine what to operate now.
[観点A21] 図19,図20などが例示するように、表示制御部(例:MCU30)は、第四コントロールオブジェクト(例:登録ボタン)が操作されると、カウント結果を対象セルに登録し、ユーザ操作を受け付けないように第四コントロールオブジェクトを再び変更してもよい。ここで、セル特定部は、対象セルを次のセルに変更する。図20および図18が例示するように、表示制御部(例:MCU30)は、取得部に検査画像の取得を指示するためのコマンドが割り当てられた第三コントロールオブジェクト(例:撮影ボタン)が操作されると、取得部に検査画像を取得させ、計数を指示するためのコマンドが第三コントロールオブジェクト(例:カウントボタン)に割り当てられてもよい。これにより、ユーザは、今、何を操作すべきかを容易に判断できるであろう。
[Viewpoint A21] As illustrated in FIGS. 19 and 20, the display control unit (e.g. MCU 30) registers the count result in the target cell when the fourth control object (e.g. registration button) is operated. , the fourth control object may be changed again so as not to accept user operations. Here, the cell specifying unit changes the target cell to the next cell. As illustrated in FIGS. 20 and 18, the display control unit (e.g. MCU 30) is operated by a third control object (e.g. shooting button) to which a command for instructing the acquisition unit to acquire an inspection image is assigned. Then, a command for causing the acquisition unit to acquire the inspection image and instructing counting may be assigned to a third control object (eg, a count button). This will allow the user to easily determine what to operate now.
[観点A22] ヘッド装置1は、たとえば、コロニー計数装置の筐体に設けられた第一ハードウエアボタンおよび第二ハードウエアボタンをさらに有してもよい。第一ハードウエアボタンと第三コントロールオブジェクトには同一の機能が割り当てられ、第二ハードウエアボタンと第四コントロールオブジェクトには同一の機能が割り当てられてもよい。これにより、ハードウエアボタンとソフトウエアボタンとを連携させることが可能となろう。ユーザが、ヘッド装置1にセットされたシャーレ15に注視している場合、ヘッド装置1のハードウエアボタンにより指示を入力することが可能となる。つまり、ユーザは、PC1bの表示装置37に視線を移し、かつ、ポインティングデバイス33を操作することなく、簡単に指示を入力できるようになろう。その一方で、ユーザが、PC1bに表示された検査画像に注視している場合、ハードウエアボタンに視線を移し、それを押すことは、作業効率を低下させるだろう。よって、この場合、表示装置37にソフトウエアボタンを表示することで、ユーザは簡単かつ正確にボタンを操作できるようになろう。
[Aspect A22] The head device 1 may further include, for example, a first hardware button and a second hardware button provided on the housing of the colony counting device. The same function may be assigned to the first hardware button and the third control object, and the same function may be assigned to the second hardware button and the fourth control object. This would allow hardware buttons and software buttons to work together. When the user is gazing at the petri dish 15 set in the head device 1, it becomes possible to input instructions using the hardware buttons of the head device 1. In other words, the user will be able to easily input instructions without looking at the display device 37 of the PC 1b and without operating the pointing device 33. On the other hand, when the user is gazing at the inspection image displayed on the PC 1b, shifting his/her gaze to a hardware button and pressing it will reduce work efficiency. Therefore, in this case, by displaying the software buttons on the display device 37, the user will be able to easily and accurately operate the buttons.
[観点A23] アプリケーションプログラム39は、コロニー計数装置を制御する制御装置において実行されるプログラムの一例である。アプリケーションプログラム39は、PC1bに、 複数の検査個体の各々のカウント結果が入力されるセルを含むカウント表を記憶部に記憶させ、 記憶部に記憶されているカウント表を表示装置に表示させ、 表示装置に表示されるカウント表に含まれる複数のセルの中から、カウント結果が入力される対象セルを特定させ、 検査個体の画像である検査画像を取得させ、 ユーザにより入力される計数指示にしたがって、取得部で取得された検査画像に基づき検査個体に含まれるコロニーの数を取得させ、 コロニーの数を対象セルに反映させる。
[Viewpoint A23] The application program 39 is an example of a program executed in a control device that controls the colony counting device. The application program 39 causes the PC 1b to store a count table including cells into which the count results of each of the plurality of test individuals are input in the storage unit, displays the count table stored in the storage unit on the display device, and displays From among the multiple cells included in the count table displayed on the device, identify the target cell into which the count results will be input, obtain the test image that is the image of the test individual, and follow the counting instructions input by the user. , the number of colonies included in the test individual is acquired based on the test image acquired by the acquisition unit, and the number of colonies is reflected in the target cell.
[観点A24] 上記の実施例によれば、コロニー計数装置1を制御する制御方法が提供される。当該制御方法は、 複数の検査個体の各々のカウント結果が入力されるセルを含むカウント表を記憶部に記憶させることと、 記憶部に記憶されているカウント表を表示装置に表示することと、 表示装置に表示されるカウント表に含まれる複数のセルの中から、カウント結果が入力される対象セルを特定することと、 検査個体の画像である検査画像を取得することと、 ユーザにより入力される計数指示にしたがって、取得部で取得された検査画像に基づき検査個体に含まれるコロニーを計数することと、 計数されたコロニーの数を対象セルに反映させることと、を有する。
[Aspect A24] According to the above embodiment, a control method for controlling the colony counting device 1 is provided. The control method includes: storing in a storage unit a count table including cells into which the count results of each of a plurality of test individuals are input; displaying the count table stored in the storage unit on a display device; Among the multiple cells included in the count table displayed on the display device, the target cell into which the count result will be input is identified, the test image that is the image of the test individual is obtained, and the data input by the user is counting the colonies included in the test individual based on the test image acquired by the acquisition unit according to the counting instructions provided by the acquisition unit; and reflecting the counted number of colonies in the target cell.
[観点B1] 記憶装置35は、検査個体についてのコロニーのカウント結果が入力されるセルを含むカウント表と、当該カウント表に関連付けられた識別情報と、を記憶する記憶部として機能する。MCU30およびMCU20は、識別情報を符号化した識別画像(例:一次元シンボル、二次元シンボル)から当該識別情報を取得する識別情報取得部として機能する。MCU30は、取得部により取得された識別情報に関連付けられているカウント表を記憶部から読み出す表管理部として機能する。さらに、MCU30は、表管理部で読み出されたカウント表に含まれる複数のセルの中から、カウント結果が入力される対象セルを特定するセル特定部として機能する。MCU20またはMCU30は、ユーザの操作にしたがった計数指示を生成する計数指示部として機能する。メインカメラ11は、計数指示部で生成された計数指示に基づいて検査個体の画像である検査画像を生成する第一撮像部として機能する。MCU20またはMCU30は、前記第一撮像部で生成された検査画像に基づき検査個体に含まれるコロニーを計数する計数部として機能する。表管理部(例:MCU30)は、セル特定部で特定された対象セルに、計数部により計数されたコロニーの数を反映するように構成されている。このように、識別画像から、カウント結果を入力されることになるカウント表が特定されて表示されるため、コロニーの計数に関するユーザの負担が軽減される。
[Aspect B1] The storage device 35 functions as a storage unit that stores a count table including cells into which colony count results for the test individual are input, and identification information associated with the count table. The MCU 30 and the MCU 20 function as an identification information acquisition unit that acquires the identification information from an identification image (eg, one-dimensional symbol, two-dimensional symbol) in which the identification information is encoded. The MCU 30 functions as a table management unit that reads the count table associated with the identification information acquired by the acquisition unit from the storage unit. Furthermore, the MCU 30 functions as a cell specifying section that specifies a target cell into which a count result is input from among a plurality of cells included in the count table read out by the table management section. The MCU 20 or MCU 30 functions as a counting instruction unit that generates counting instructions according to user operations. The main camera 11 functions as a first imaging section that generates a test image, which is an image of the test object, based on the counting instruction generated by the counting instruction section. The MCU 20 or MCU 30 functions as a counting unit that counts colonies included in the tested individual based on the test image generated by the first imaging unit. The table management unit (eg, MCU 30) is configured to reflect the number of colonies counted by the counting unit in the target cell specified by the cell specifying unit. In this way, the count table into which the count results are input is identified and displayed from the identification image, so the burden on the user regarding colony counting is reduced.
[観点B2] 識別情報取得部は、第一撮像部(例:メインカメラ11)により撮像された識別画像から識別情報を取得するように構成されていてもよい。このように、検査個体を撮像する撮像部を、識別画像を撮像する撮像部として兼用してもよい。
[Aspect B2] The identification information acquisition unit may be configured to acquire identification information from an identification image captured by the first imaging unit (eg, main camera 11). In this way, the imaging unit that images the test individual may also be used as the imaging unit that images the identification image.
[観点B3] 識別情報取得部は第二撮像部を有してもよい。フロントカメラ10は、識別画像を撮像する第二撮像部の一例である。識別情報取得部(例:MCU20,30)は、第二撮像部により撮像された識別画像から識別情報を取得するように構成されていてもよい。
[Aspect B3] The identification information acquisition section may include a second imaging section. The front camera 10 is an example of a second imaging unit that captures an identification image. The identification information acquisition unit (eg, MCU 20, 30) may be configured to acquire identification information from the identification image captured by the second imaging unit.
[観点B4] 第二撮像部(例:フロントカメラ10)は、検査個体の外観、包装体(例:包装袋、商品パッケージ)により包装された検査個体の外観、および、当該包装体に印刷された情報のうちの少なくとも一つである付加画像を撮像するように構成されていてもよい。記憶部(例:記憶装置35)は、対象セルに対して、付加画像と、当該付加画像から取得される付加情報とのうちの少なくとも一方を関連付けて記憶してもよい。上述されたように、カウント表は、カウント結果が入力されるセルと、画像等を格納可能なセル(例:備考セル、自由列のセル)を有してもよい。この場合、後者のセルには、付加画像(例:商品外観)や付加情報(例:商品コード)が格納されるか、関連付けられてもよい。ユーザは、対象セルに関連付けられて記憶されている付加情報または付加画像を参照することで、どの検査個体についてのカウント結果であるかを、容易に把握できるようになろう。
[Viewpoint B4] The second imaging unit (e.g., front camera 10) captures the appearance of the test object, the appearance of the test object packaged in a package (e.g., packaging bag, product package), and the information printed on the package. The device may be configured to capture an additional image that is at least one of the added information. The storage unit (eg, storage device 35) may store at least one of an additional image and additional information acquired from the additional image in association with the target cell. As described above, the count table may have cells into which count results are input and cells in which images and the like can be stored (eg, notes cells, free column cells). In this case, additional images (eg, product appearance) and additional information (eg, product code) may be stored in or associated with the latter cell. By referring to the additional information or the additional image stored in association with the target cell, the user will be able to easily understand which individual to be examined corresponds to the count result.
[
観点B5] カウント表は、付加画像と付加情報とのうちの少なくとも一方を保持する付加セル(例:備考セル、自由列のセル)を含んでもよい。ユーザは、付加セルに保持されている付加情報または付加画像を参照することで、どの検査個体についてのカウント結果であるかを、容易に把握できるようになろう。 [
Viewpoint B5] The count table may include additional cells (eg, notes cells, free column cells) that hold at least one of an additional image and additional information. By referring to the additional information or the additional image held in the additional cell, the user will be able to easily understand which test individual the count results are for.
観点B5] カウント表は、付加画像と付加情報とのうちの少なくとも一方を保持する付加セル(例:備考セル、自由列のセル)を含んでもよい。ユーザは、付加セルに保持されている付加情報または付加画像を参照することで、どの検査個体についてのカウント結果であるかを、容易に把握できるようになろう。 [
Viewpoint B5] The count table may include additional cells (eg, notes cells, free column cells) that hold at least one of an additional image and additional information. By referring to the additional information or the additional image held in the additional cell, the user will be able to easily understand which test individual the count results are for.
[観点B6] 図29や図40が示すように、MCU30およびポインタ57は、カウント表に存在する複数の付加セルから一つの付加セルを選択する選択部として機能してもよい。さらに、MCU30は、選択部により選択された一つの付加セルに、付加画像と付加情報とのうちの少なくとも一方を登録する付加情報登録部として機能してもよい。これにより、ユーザは、カウント表において希望するセルに対して付加画像や付加情報を登録することができる。
[Aspect B6] As shown in FIGS. 29 and 40, the MCU 30 and the pointer 57 may function as a selection unit that selects one additional cell from a plurality of additional cells present in the count table. Furthermore, the MCU 30 may function as an additional information registration unit that registers at least one of an additional image and additional information in one additional cell selected by the selection unit. This allows the user to register additional images and additional information for desired cells in the count table.
[観点B7] MCU30は、対象セルに関連付けられている検査個体の識別情報(例:サンプル名、シャーレ番号)を入手する入手部として機能してもよい。記憶部は、ユーザにより入力される計数指示により第一撮像部により撮像された検査個体の検査画像を検査個体の識別情報と関連付けて記憶するように構成されていてもよい。従来、検査画像と検査個体との関係を正しく記録することは多くの工数が必要であった。たとえば、デジタルカメラで検査画像を取得することが考えられるが、この場合、検査画像と検査個体の識別情報とを人手による紐づけすること必要となるだろう。また、人手による紐づけは、ヒューマンエラーの原因となる。本実施例では、MCU30が対象セルを特定し、かつ、対象セルに関連付けられている検査個体の識別情報に対して検査個体の検査画像を関連付ける。よって、従来によりユーザに必要とされる項数が削減され、かつ、検査個体の検査画像と検査個体の識別情報との関係を正しく記録することが可能となる。
[Aspect B7] The MCU 30 may function as an acquisition unit that acquires identification information (eg, sample name, petri dish number) of the test individual associated with the target cell. The storage unit may be configured to store an inspection image of the inspection individual captured by the first imaging unit in response to a counting instruction input by the user in association with identification information of the inspection individual. Conventionally, it has required a lot of man-hours to correctly record the relationship between an inspection image and an inspection individual. For example, it is conceivable to acquire test images with a digital camera, but in this case, it would be necessary to manually link the test images and the identification information of the test individual. Furthermore, manual linking may cause human error. In this embodiment, the MCU 30 identifies the target cell and associates the inspection image of the inspection individual with the identification information of the inspection individual associated with the target cell. Therefore, the number of items conventionally required by the user is reduced, and it becomes possible to correctly record the relationship between the inspection image of the inspection individual and the identification information of the inspection individual.
[観点B8] 図33が例示するように、MCU30は、検査個体の識別情報と、計数部により計数されたコロニーの数と、検査個体の検査画像と、を含むレポートを生成するレポート生成部として機能してもよい。これにより、ユーザは、どのサンプルの計測結果であるかを直感的に把握できるようになろう。
[Viewpoint B8] As illustrated in FIG. 33, the MCU 30 functions as a report generation unit that generates a report including the identification information of the tested individual, the number of colonies counted by the counting unit, and the inspection image of the tested individual. It may work. With this, the user will be able to intuitively understand which sample the measurement result is.
[観点B9] カウント表においてコロニーの数を入力されるセルには固有のセル識別情報が付与されていてもよい。図41が示すように、MCU30は、固有のセル識別情報を符号化した識別画像221をプリンタ38によりシール270(粘着面を有する樹脂または紙)に印刷してもよい。ユーザは、シャーレ15の側面にシール270を貼り付ける。なお、シャーレ番号は、固有のセル識別情報として利用されてもよい。識別情報取得部(例:MCU30、フロントカメラ10またはメインカメラ11)は、セル識別情報を取得するように構成されていてもよい。セル特定部(例:MCU30)は、識別情報取得部により取得されたセル識別情報に基づき対象セルを特定してもよい。これにより、ユーザが対象セルを指定する手間が省けるようになる。さらに、検査個体に対応した対象セルが正確に特定されるようになろう。
[Aspect B9] Unique cell identification information may be given to the cell into which the number of colonies is input in the count table. As shown in FIG. 41, the MCU 30 may use the printer 38 to print an identification image 221 that encodes unique cell identification information on a sticker 270 (resin or paper with an adhesive surface). The user attaches a sticker 270 to the side of the Petri dish 15. Note that the petri dish number may be used as unique cell identification information. The identification information acquisition unit (eg, MCU 30, front camera 10, or main camera 11) may be configured to acquire cell identification information. The cell identification unit (eg, MCU 30) may identify the target cell based on the cell identification information acquired by the identification information acquisition unit. This saves the user the trouble of specifying the target cell. Furthermore, the target cell corresponding to the test individual will be accurately identified.
[観点B10] 図28が示すように、識別情報取得部(例:MCU30)は、第一撮像部または第二撮像部によりユーザ認証情報を取得してもよい。これにより、ユーザ認証用の専用のカメラやコードリーダーを省略できるようになろう。
[Aspect B10] As shown in FIG. 28, the identification information acquisition unit (eg, MCU 30) may acquire user authentication information using the first imaging unit or the second imaging unit. This will make it possible to omit a dedicated camera or code reader for user authentication.
[観点B11] 図27が例示するように、識別情報取得部(例:MCU30、フロントカメラ10またはメインカメラ11)は、印刷媒体(例:検査リスト220)に印刷された識別画像から識別情報を取得するように構成されていてもよい。
[Viewpoint B11] As illustrated in FIG. 27, the identification information acquisition unit (e.g. MCU 30, front camera 10 or main camera 11) acquires identification information from the identification image printed on the print medium (e.g. inspection list 220). The information may be configured to be obtained.
[観点B12] MCU30は、カウント表と、当該カウント表に関連付けられた識別情報とを含む検査リストのデータを作成するデータ作成部として機能してもよい。
[Aspect B12] The MCU 30 may function as a data creation unit that creates test list data that includes a count table and identification information associated with the count table.
[観点B13] 識別情報取得部(例:MCU30、フロントカメラ10またはメインカメラ11)は、端末装置1cに表示された識別画像から識別情報を取得するように構成されていてもよい。これにより、紙媒体を削減することが可能となる。

[観点B14] 通信回路34は、端末装置1cと通信し、端末装置1cに識別画像を送信する通信部の一例である。
[Aspect B14] The communication circuit 34 is an example of a communication unit that communicates with the terminal device 1c and transmits an identification image to the terminal device 1c.
[観点B15] MCU30は、ユーザ操作に応じてカウント表を作成し、記憶部に当該カウント表を記憶させる作成部として機能してもよい。
[Aspect B15] The MCU 30 may function as a creation unit that creates a count table in response to user operations and stores the count table in the storage unit.
[観点B16] 作成部(例:MCU30)は、コロニーの数のカウント結果を格納するセルに対して検査条件を関連付けてもよい。第一撮像部は、検査条件(例:露光時間、照明の種類、明るさ)にしたがって検査個体を撮像するように構成されていてもよい。
[Viewpoint B16] The creation unit (eg, MCU 30) may associate test conditions with cells that store the result of counting the number of colonies. The first imaging unit may be configured to image the individual to be inspected according to inspection conditions (eg, exposure time, type of illumination, brightness).
[観点B17] コロニー計数装置1は、第一撮像部を有する筐体(例:上部ユニット2、支持ユニット3および下部ユニット4)をさらに有してもよい。
[Viewpoint B17] The colony counting device 1 may further include a housing (eg, upper unit 2, support unit 3, and lower unit 4) having a first imaging section.
筐体は、検査個体を収容したシャーレ15を保持するステージ5と、検査個体を照明する照明部(例:リング照明装置12、13、同軸照明装置14)と、ユーザにより入力される計数指示を受け付ける受付部(例:第一ハードウエアボタン8a)と、を有してもよい。
The casing includes a stage 5 that holds a petri dish 15 containing test specimens, a lighting section (e.g. ring lighting devices 12, 13, coaxial lighting device 14) that illuminates the test specimens, and a counting instruction input by the user. It may also include a reception unit (eg, first hardware button 8a) that accepts the request.
[観点B18] コロニー計数装置1は、第一撮像部および第二撮像部を有する筐体(例:上部ユニット2、支持ユニット3および下部ユニット4)をさらに有してもよい。筐体は、検査個体を収容したシャーレ15を保持するステージ5と、検査個体を照明する照明部(例:リング照明装置12、13、同軸照明装置14)と、ユーザにより入力される計数指示を受け付ける受付部(例:第一ハードウエアボタン8a)とを有してもよい。さらに、筐体は、凹部4aを有してもよい。第二撮像部(例:フロントカメラ10)は、凹部に配置されていてもよい。受付部(例:第一ハードウエアボタン8a)は、ステージと凹部との間にある操作部(操作部8)に配置されていてもよい。これにより、簡単に、計数指示を入力することが可能となる。
[Viewpoint B18] The colony counting device 1 may further include a housing (eg, upper unit 2, support unit 3, and lower unit 4) that includes a first imaging section and a second imaging section. The casing includes a stage 5 that holds a petri dish 15 containing test specimens, a lighting section (e.g. ring lighting devices 12, 13, coaxial lighting device 14) that illuminates the test specimens, and a counting instruction input by the user. It may also include a reception unit (eg, first hardware button 8a) that accepts the request. Furthermore, the housing may have a recess 4a. The second imaging unit (eg, front camera 10) may be placed in the recess. The reception section (eg, first hardware button 8a) may be arranged in an operation section (operation section 8) between the stage and the recess. This makes it possible to easily input counting instructions.
[観点B19] コロニー計数装置1が第一状態にあるときに受付部(例:第一ハードウエアボタン8a)が撮像指示を受け付けると、第一撮像部が撮像を実行してもよい。コロニー計数装置1が第一状態と異なる第二状態にあるときに受付部が撮像指示を受け付けると、第二撮像部が撮像を実行してもよい。これにより、単一の受付部に対する同一の操作であるにも拘らず、異なる撮像部に撮像を指示することが可能となる。第一状態とは、たとえば、カウント表がすでに特定された状態である。第二状態とは、たとえば、カウント表がまだ特定されていない状態である。
[Viewpoint B19] When the reception unit (eg, first hardware button 8a) receives an imaging instruction when the colony counting device 1 is in the first state, the first imaging unit may perform imaging. If the reception unit receives an imaging instruction while the colony counting device 1 is in a second state different from the first state, the second imaging unit may perform imaging. This makes it possible to instruct different imaging units to capture images even though the same operation is performed on a single reception unit. The first state is, for example, a state in which a count table has already been specified. The second state is, for example, a state where the count table has not yet been specified.
