I can know. In other words, the user can learn which condition item of the first shooting condition is changed to which side by simply selecting an image that matches his / her preference, and can shoot his / her own shooting. It is possible to improve the technology and increase the knowledge about shooting.
　また、上記態様においては、前記情報読出部が、前記画像情報記憶部に記憶されている前記差情報を読み出し、前記表示部が、前記条件項目情報に関連づけて前記差情報を表示してもよい。
　このようにすることで、ユーザがいずれかの画像情報を選択すると、選択された画像情報が第１撮影条件に対してどの条件項目をどちらの方向にどれだけ変更して撮影されたものであるかを知ることができる。すなわち、ユーザは、自らの好みに合致する画像を選択するだけで、その画像が第１撮影条件のどの条件項目をどちら側にどれだけ変更して撮影されたものであるかを学習でき、自らの撮影技術の向上および撮影に関する知識の増加を図ることができる。 In the above aspect, the information reading unit may read the difference information stored in the image information storage unit, and the display unit may display the difference information in association with the condition item information. .
In this way, when the user selects any image information, the selected image information is captured by changing which condition item in which direction and how much with respect to the first imaging condition. Can know. In other words, the user can learn which one of the first shooting conditions is changed and which one of the first shooting conditions is changed by simply selecting an image that matches his / her preference. It is possible to improve the shooting technique and increase the knowledge about shooting.
　また、上記態様においては、前記画像情報記憶部が、前記差情報として、前記第１撮影条件および前記第２撮影条件を記憶し、前記情報読出部が、前記第１撮影条件と前記第２撮影条件との差異を抽出する差情報抽出部を備えていてもよい。
　このようにすることで、ユーザがいずれかの画像を選択すると選択された画像の画像情報と該画像情報に対応づけられている差情報として第１撮影条件および第２撮影条件が情報読出部により読み出される。第１撮影条件および第２撮影条件を読み出した情報読出部は第１撮影条件と第２撮影条件との差異を抽出し、差異が抽出された条件項目に対応する条件項目情報が条件項目情報記憶部から読み出される。これにより記録時に差異を抽出する必要がない。 In the above aspect, the image information storage unit stores the first shooting condition and the second shooting condition as the difference information, and the information reading unit stores the first shooting condition and the second shooting condition. You may provide the difference information extraction part which extracts the difference with conditions.
In this way, when the user selects any image, the information reading unit sets the first image capturing condition and the second image capturing condition as the difference information associated with the image information of the selected image and the image information. Read out. The information reading unit that has read the first photographing condition and the second photographing condition extracts the difference between the first photographing condition and the second photographing condition, and the condition item information corresponding to the condition item from which the difference is extracted is stored in the condition item information. Read from the section. This eliminates the need to extract differences during recording.
　また、上記態様においては、前記画像情報記憶部が、前記差情報として、前記第１撮影条件と前記第２撮影条件との差異を記憶してもよい。
　このようにすることで、ユーザがいずれかの画像を選択すると選択された画像の画像情報と該画像情報に対応づけられている差情報として第１撮影条件と第２撮影条件との差異が情報読出部により読み出される。情報読出部は読み出したが存在する条件項目に対応する条件項目情報を条件項目情報記憶部から読み出す。これにより読出時に差異を抽出する必要がない。 In the aspect described above, the image information storage unit may store a difference between the first shooting condition and the second shooting condition as the difference information.
Thus, when the user selects any image, the difference between the first shooting condition and the second shooting condition is information as the difference information associated with the image information of the selected image and the image information. Read by the reading unit. The information reading unit reads out the condition item information corresponding to the condition item that has been read out from the condition item information storage unit. This eliminates the need to extract differences during reading.
　また、本発明の他の態様は、前記第１撮影条件を自動設定して撮影を行うフルオート撮影モードと、ユーザが撮影条件を手動で前記第１撮影条件から変更して撮影を行うユーザ設定オート撮影モードとを切り替えて画像を取得可能な撮像部と、上記いずれかの画像処理装置とを備える画像取得装置である。 According to another aspect of the present invention, there is provided a fully automatic shooting mode in which shooting is performed by automatically setting the first shooting condition, and a user setting in which a user manually changes shooting conditions from the first shooting condition.

As shown in FIG. 1, the image acquisition device 1 according to the present embodiment includes an imaging unit 2 that captures image information by capturing a subject, a first imaging condition acquisition unit 3 that acquires imaging conditions, and a second imaging. A condition acquisition unit 4 and an image processing device 5 that processes image information acquired by the imaging unit 2 are provided.
　撮像部２は、撮影環境に応じた第１撮影条件を自動設定して撮影を行うフルオート撮影モードと、ユーザが撮影条件を手動で第１撮影条件から変更して第２撮影条件によって撮影を行うユーザ設定オート撮影モードとを切り替えて画像を取得することができるものである。 The imaging unit 2 automatically sets the first shooting condition according to the shooting environment and performs shooting according to the second shooting condition by manually changing the shooting condition from the first shooting condition. The image can be acquired by switching between the user-set auto shooting mode to be performed.
　第１撮影条件取得部３は、撮像部２により自動設定された第１撮影条件を取得するようになっている。また、第２撮影条件取得部４は、撮像部２により撮影が行われた際の撮影条件を第２撮影条件として取得するようになっている。これら第１撮影条件取得部３および第２撮影条件取得部４は、各種センサ（図示略）を備えている。 The first imaging condition acquisition unit 3 acquires the first imaging condition automatically set by the imaging unit 2. Further, the second imaging condition acquisition unit 4 acquires the imaging condition when the imaging unit 2 performs imaging as the second imaging condition. The first imaging condition acquisition unit 3 and the second imaging condition acquisition unit 4 include various sensors (not shown).
　本実施形態に係る画像処理装置５は、撮像部２により取得された画像情報と、第１撮影条件取得部３により取得された第１撮影条件と、第２撮影条件取得部４により取得された第２撮影条件とを対応づけて記憶する画像情報記憶部６と、撮影条件の各条件項目を表すアシスト情報（条件項目情報）を記憶するアシスト情報データベース（条件項目情報記憶部）７と、画像情報記憶部６に記憶されている画像情報を表示してユーザに選択させる画像選択部１０と、画像選択部１０により選択された画像に対応する画像情報と、該画像情報に対応づけて記憶されている第１撮影条件および第２撮影条件とを画像情報記憶部６から読み出す情報読出部９と、該情報読出部９により読み出された第１撮影条件と第２撮影条件との差異を表す差情報を抽出し、差情報が存在する条件項目に対応するアシスト情報をアシスト情報データベース７から読み出して、画像情報とともに表示部８に表示させる差情報抽出部１１と、画像情報およびアシスト情報を表示する表示部８とを備えている。 The image processing apparatus 5 according to the present embodiment is acquired by the image information acquired by the imaging unit 2, the first imaging condition acquired by the first imaging condition acquisition unit 3, and the second imaging condition acquisition unit 4. An image information storage unit 6 that stores the second shooting conditions in association with each other, an assist information database (condition item information storage unit) 7 that stores assist information (condition item information) representing each condition item of the shooting conditions, and an image The image selection unit 10 that displays image information stored in the information storage unit 6 and allows the user to select the image, the image information corresponding to the image selected by the image selection unit 10, and the image information are stored in association with the image information. The information reading unit 9 that reads the first shooting condition and the second shooting condition that are read from the image information storage unit 6 and the difference between the first shooting condition and the second shooting condition that are read by the information reading unit 9 Difference information The difference information extracting unit 11 that reads out the assist information corresponding to the condition item having difference information from the assist information database 7 and displays it on the display unit 8 together with the image information, and the display unit 8 that displays the image information and the assist information. And.
　画像情報記憶部６には、例えば、図２Ａおよび図２Ｂに示されるように、撮影条件の条件項目毎に、第１撮影条件に対応する第１設定値および第２撮影条件に対応する第２設定値が対応づけられるとともに、第２撮影条件により撮影された画像情報が対応付けられて記憶されるようになっている。図２Ｂは上記情報を対応づけたメタデータの一例を示している。
　条件項目としては、例えば、露出、Ｆ値、ホワイトバランスおよびピクチャーモードが挙げられるがこれに限定されるものではない。 For example, as shown in FIGS. 2A and 2B, the image information storage unit 6 stores, for each condition item of the shooting condition, the first set value corresponding to the first shooting condition and the second corresponding to the second shooting condition. The setting values are associated with each other, and image information photographed under the second photographing condition is associated and stored. FIG. 2B shows an example of metadata in which the above information is associated.
Examples of condition items include, but are not limited to, exposure, F value, white balance, and picture mode.
　すなわち、撮像部２による撮影が行われるときに、フルオート撮影モードにおいては、第１撮影条件が第１撮影条件取得部３により取得されて、撮像部２により取得された画像情報とともに画像情報記憶部６に記憶される。一方、ユーザ設定オート撮影モードにおいては、第１撮影条件取得部３により取得された第１撮影条件および第２撮影条件取得部４により取得された第２撮影条件が、撮像部２により取得された画像情報とともに画像情報記憶部６に記憶されるようになっている。 That is, when shooting by the imaging unit 2 is performed, in the fully automatic shooting mode, the first shooting condition is acquired by the first shooting condition acquisition unit 3, and the image information is stored together with the image information acquired by the imaging unit 2.

The image information is stored in the image information storage unit 6 together with the image information.
　アシスト情報データベース７は、例えば、図３に示されるように、各条件項目毎に、差異と、該差異に対応する説明と、ピクトグラムとからなるアシスト情報を対応付けて記憶している。差異は第１撮影条件に対する第２撮影条件の変更の方向を表す符号または変更された条件そのものを示している。また、差異に対する説明は、差異を実現するための操作を言葉で表現したものである。ピクトグラムは、条件項目を表すイメージ（アイコン）である。 For example, as shown in FIG. 3, the assist information database 7 stores assist information including a difference, a description corresponding to the difference, and a pictogram in association with each condition item. The difference indicates a sign indicating the direction of change of the second imaging condition with respect to the first imaging condition or the changed condition itself. Further, the explanation for the difference expresses the operation for realizing the difference in words. A pictogram is an image (icon) representing a condition item.
　画像選択部１０は、ユーザがユーザ設定オート撮影モードに切り替える操作によって、図４に示されるように、画像情報記憶部６に記憶されている１以上の画像情報を読み出して表示部８に表示させ、ユーザに、好みの画像を選択させるようになっている。ユーザが好みの画像を選択すると、情報読出部９は、図２Ｂに示されるように、選択された画像情報と、該画像情報に対応づけて記憶されている第１撮影情報および第２撮影情報とを読み出すようになっている。 The image selection unit 10 reads out one or more pieces of image information stored in the image information storage unit 6 and displays them on the display unit 8 as shown in FIG. The user is allowed to select a favorite image. When the user selects a favorite image, the information reading unit 9, as shown in FIG. 2B, the selected image information and the first shooting information and the second shooting information stored in association with the image information. And are read out.
　そして、情報読出部９に接続された差情報抽出部１１は、読み出した第１撮影情報と第２撮影情報との差異を表す差情報を条件項目毎に抽出する。図２Ａに示されるように、第１撮影条件および第２撮影条件が、条件項目として、露出、Ｆ値、ホワイトバランス、およびピクチャーモードを備えている場合に、差情報抽出部１１は、各条件項目毎に差異が存在するか否かを判定し、差異が存在するものについて、差異の方向性または内容とそれらの説明とをアシスト情報データベース７からピクトグラムとともに読み込んで、画像情報とともに表示部８に表示するようになっている。 Then, the difference information extraction unit 11 connected to the information reading unit 9 extracts the difference information indicating the difference between the read first shooting information and the second shooting information for each condition item. As shown in FIG. 2A, when the first shooting condition and the second shooting condition include exposure, F value, white balance, and picture mode as condition items, the difference information extraction unit 11 It is determined whether or not there is a difference for each item, and the direction or content of the difference and the description thereof are read together with the pictogram from the assist information database 7 for the item with the difference, and are displayed on the display unit 8 together with the image information. It is supposed to be displayed.
　図５に示す例では、第１撮影条件と第２撮影条件とは、露出、ホワイトバランスおよびピクチャーモードにおいて差異があり、これら３つの条件項目を表すピクトグラムが、アシスト情報データベース７から読み出されて表示される。また、露出については、第１撮影条件から第２撮影条件への変更が０．０から＋３．０への変更であり、明るくする方向への変更であるため、差異の方向を表す符号「＋」に対応する説明として「明るく」がアシスト情報データベース７から読み出され、「露出」を表すピクトグラムに対応する位置に表示されるようになっている。 In the example shown in FIG. 5, the first shooting condition and the second shooting condition are different in exposure, white balance, and picture mode, and a pictogram representing these three condition items is read from the assist information database 7. Is displayed. Regarding exposure, since the change from the first shooting condition to the second shooting condition is a change from 0.0 to +3.0 and a change to a brightening direction, a sign “+” indicating the direction of the difference. "Bright" is read from the assist information database 7 as an explanation corresponding to "" and displayed at a position corresponding to a pictogram representing "exposure".
　また、ホワイトバランスについては、第１撮影条件から第２撮影条件への変更が、５５００から４０００への暖色側への変更であるため、差異に対する説明として「暖色側へ」がアシスト情報データベース７から読み出され、「ホワイトバランス」を表すピクトグラムに対応する位置に表示されるようになっている。
　さらに、ピクチャーモードについては、第１撮影条件から第２撮影条件への変更が、ナチュラルからビビッドへの変更であるため、差異の内容に対する説明として「ビビッドに設定して」がアシスト情報データベース７から読み出され、「ピクチャーモード」を表すピクトグラムに対応する位置に表示されるようになっている。 Regarding the white balance, since the change from the first shooting condition to the second shooting condition is a change from 5500 to 4000 on the warm color side, “to warm color side” is explained from the assist information database 7 as an explanation for the difference. It is read out and displayed at a position corresponding to a pictogram representing “white balance”.
Furthermore, for the picture mode, since the change from the first shooting condition to the second shooting condition is a change from natural to vivid, “set to vivid” is described from the assist information database 7 as an explanation for the content of the difference. It is read out and displayed at a position corresponding to the pictogram representing the “picture mode”.
　このように構成された本実施形態に係る画像取得装置１および画像処理装置５の作用について以下に説明する。
