Although not shown in FIG. 1, the list creation unit 116 may attach the product image acquired by the product image acquisition unit 115 to the shopping list.
続いて、購買支援装置としての画像形成装置１による購買支援の具体例を説明する。 Next, a specific example of purchase support by the image forming apparatus 1 as a purchase support apparatus will be described.
まずユーザーは、購入したい品物、又は複数の店舗にて販売価格を比較したい品物をまとめた買い物メモ９１を作成する。この買い物メモ９１は、ユーザーによる手書きでもよいし、パソコンや携帯端末等で作成した文書データの印刷物であってもよい。 First, the user creates a shopping memo 91 in which items to be purchased or items whose selling prices are to be compared at a plurality of stores are collected. The shopping memo 91 may be handwritten by the user, or may be a printed matter of document data created by a personal computer or a portable terminal.
そして、ユーザーは、購入したい商品が販売されている店舗の広告チラシを用意する。本実施の形態ではＡスーパーのチラシ９２とＢスーパーのチラシ９３を例に挙げる。 Then, the user prepares an advertisement flyer of a store where a product to be purchased is sold. In the present embodiment, a supermarket leaflet 92 and a supermarket leaflet 93 are taken as examples.
次に、ユーザーは画像形成装置１の画像読取部１３に対して買い物メモ９１、チラシ９２及びチラシ９３の画像読み取りを行わせる。画像読取部１３は買い物メモ９１、チラシ９２及びチラシ９３を読み取ってそれぞれの画像を取得し、画像形成装置１が有する文字認識部１１１がＯＣＲ（Optical Character Recognition）技術等を用いてそれぞれの画像から文字を識別し、文字データへと変換する。 Next, the user causes the image reading unit 13 of the image forming apparatus 1 to read the images of the shopping memo 91, the leaflet 92, and the leaflet 93. The image reading unit 13 reads the shopping memo 91, the leaflet 92, and the leaflet 93 to acquire respective images, and the character recognition unit 111 included in the image forming apparatus 1 uses the OCR (Optical Character Recognition) technology or the like from each image. Identify characters and convert them to character data.
そして、文字抽出部１１２が、文字認識部１１１が識別した買い物メモ９１の文字からメモ物品名としての文字列を抽出し、文字認識部１１１が識別した広告画像の文字から広告商品名としての文字列を抽出する。 Then, the character extraction unit 112 extracts a character string as a memo article name from the characters of the shopping memo 91 identified by the character recognition unit 111, and the characters as the advertisement product name from the characters of the advertisement image identified by the character recognition unit 111. Extract columns.
更に、画像形成装置１が有する文字検索部１１３は、チラシ９２とチラシ９３から認識された広告商品名から、買い物メモ９１から認識されたメモ物品名を含む広告商品名を検索する。例えば、あるメモ物品名が「牛乳」である場合、文字検索部１１３はチラシ９２及び９３の広告商品名から「牛乳」を含む広告商品名を検索する。 Further, the character search unit 113 included in the image forming apparatus 1 searches for the advertisement product name including the memo article name recognized from the shopping memo 91 from the advertisement product names recognized from the leaflet 92 and the leaflet 93. For example, when a certain memo article name is “milk”, the character search unit 113 searches for the advertisement product name including “milk” from the advertisement product names of the flyers 92 and 93.
文字検索部１１３がチラシ９２又はチラシ９３から「牛乳」を検索できた場合、商品情報取得部１１４が「牛乳」の商品情報を各チラシから取得する。例えば「牛乳」はチラシ９２及び９３の両方に掲載されているため、商品情報取得部１１４は文字認識部１１１のチラシ９２及び９３のそれぞれの認識結果から「牛乳」の価格等を商品情報として取得する。商品情報取得部１１４は、例えば、文字認識部１１１のチラシ９２及び９３のそれぞれの認識結果から「牛乳」の近傍位置に、「価格」の文字に続く数字、又は「￥」、「円」、「ｙｅｎ」、「$」、「ドル」、「元」等の文字に続く数字を検索し、商品情報として取得する。商品情報は、商品に関する様々な情報であり、例えば価格の他に、販売店舗名、産地、量、付加特典等があげられる。商品情報取得部１１４は、例えば、販売店舗名、産地、量、付加特典等の商品情報を、「店」、「産」、「グラム」、「ポイント」「クーポン」等の文字を検索して、これらの文字に続く文字情報を抽出することにより取得する。 When the character search unit 113 can search for “milk” from the leaflet 92 or the leaflet 93, the product information acquisition unit 114 acquires the product information of “milk” from each leaflet. For example, since “milk” is listed in both leaflets 92 and 93, the product information acquisition unit 114 acquires the price of “milk” as product information from the recognition results of the leaflets 92 and 93 of the character recognition unit 111. To do. The product information acquisition unit 114, for example, from the recognition results of the leaflets 92 and 93 of the character recognition unit 111, in the vicinity of “milk”, a number following the characters “price”, or “¥”, “yen”, The numbers following characters such as “yen”, “$”, “dollar”, “yuan”, etc. are searched and acquired as product information. The merchandise information is various information relating to the merchandise, and includes, for example, a store name, a production area, an amount, and an additional privilege in addition to the price. The merchandise information acquisition unit 114 searches for characters such as “store”, “production”, “gram”, “point”, “coupon”, etc., for example, merchandise information such as the store name, production center, quantity, and additional benefits. The character information following these characters is obtained by extraction.
そして画像形成装置１のリスト作成部１１６は、文字検索部１１３の検索結果と商品情報取得部１１４が取得した商品情報に基づいて、買い物リスト９９を作成する。例えばメモ物品名「牛乳」については、ＡスーパーとＢスーパーの両方のチラシの広告商品名から検出されているため、リスト作成部１１６はそれぞれの店舗名及び各店舗での価格（１０９円、１２０円）が分かるようにリストを作成する。 The list creation unit 116 of the image forming apparatus 1 creates the shopping list 99 based on the search result of the character search unit 113 and the product information acquired by the product information acquisition unit 114. For example, since the memo article name “milk” is detected from the advertisement product name of the flyers of both the A supermarket and the B supermarket, the list creating unit 116 displays the name of each store and the price at each store (109 yen, 120 yen). Create a list so that you can see the circle.
更に、買い物メモ９１に記載されている「牛肉」については、Ａスーパーは国産牛、Ｂスーパーは輸入牛と、各牛肉の産地が記載されている。リスト作成部１１６は商品情報として価格と共に産地を買い物リスト９９に掲載する。 Furthermore, as for “beef” described in the shopping memo 91, A supermarket describes domestic beef, B supermarket imports, and the production area of each beef. The list creation unit 116 posts the production area along with the price as product information in the shopping list 99.
また、買い物メモ９１に記載されている「卵」も同様に、ＡスーパーとＢスーパーの両方のチラシに掲載されているが、Ｂスーパーのチラシには、顧客に与えられる特典ポイントが通常の２倍との付加特典が掲載されている。リスト作成部１１６は、商品情報取得部１１４が取得した商品情報に基づいて、この付加特典も商品情報として買い物リスト９９に掲載する。このように、販売価格の他に、産地や付加特典の違いが買い物リスト９９に掲載されることで、ユーザーは単に価格だけでなく、様々な販売情報を比較して購入を検討することができる。 Similarly, “egg” described in the shopping memo 91 is also posted on flyers of both A supermarket and B supermarket, but the bonus points given to customers are usually 2 on the supermarket flyer. Additional benefits with double are posted. Based on the product information acquired by the product information acquisition unit 114, the list creation unit 116 also posts this additional privilege on the shopping list 99 as product information. In this way, in addition to the sales price, differences in the production area and additional benefits are posted in the shopping list 99, so that the user can consider purchases by comparing not only prices but also various sales information. .
更に、買い物メモ９１に記載されている「キャベツ」は、ＡスーパーとＢスーパーのチラシのどちらにも掲載されていない。つまり、文字検索部はチラシ９２とチラシ９３から認識された文字から「キャベツ」を検索できなかったことになる。この場合、リスト作成部１１６は「広告掲載無し」と記載する。そして後述するが、画像形成装置１が有する未抽出品記憶部１６１は、メモ物品名のうち、広告掲載のなかったメモ物品名を未抽出文字として記憶する。 Further, “cabbage” described in the shopping memo 91 is not listed on the flyers of the A supermarket and the B supermarket. That is, the character search unit could not search for “cabbage” from the characters recognized from the leaflet 92 and the leaflet 93. In this case, the list creation unit 116 describes “no advertisement placement”. As will be described later, the unextracted product storage unit 161 included in the image forming apparatus 1 stores a memo article name that has not been advertised among memo article names as an unextracted character.
例えば、買い物リスト９９に記載された「バナナ」は、買い物メモ９１には記載がないが、未抽出品記憶部１６１が記憶している未抽出文字である。つまり、以前の買い物メモには記載されていたが、そのときの広告チラシには「バナナ」の掲載がなかったため、文字検索部が「バナナ」の文字を検索できず、未抽出品記憶部が「バナナ」を未抽出文字として記憶していたのである。 For example, “banana” described in the shopping list 99 is not extracted in the shopping memo 91 but is an unextracted character stored in the unextracted product storage unit 161. In other words, it was written in the previous shopping memo, but because the advertisement flyer at that time did not include “banana”, the character search unit could not search for the characters “banana” and the unextracted product storage unit “Banana” was stored as an unextracted character.
そこで、文字検索部１１３は未抽出品記憶部１６１が記憶する過去のメモ物品名である「バナナ」をチラシ９２及び９３の広告商品名から検索する。そして検索された場合には、リスト作成部１１６は買い物リスト９９に「バナナ」の商品情報を記載する。こうすることで、過去に購入しようと思っていたが、広告掲載がなかったために購入しなかった商品を買い物リスト９９に載せることができ、買い忘れ等を防ぎ、更に購買促進を図ることができる。 Therefore, the character search unit 113 searches the advertisement product names of the leaflets 92 and 93 for “banana”, which is a past memo article name stored in the unextracted product storage unit 161. When the search is made, the list creation unit 116 describes the product information of “banana” in the shopping list 99. In this way, products that were intended to be purchased in the past but were not purchased due to the absence of advertisements can be placed on the shopping list 99, so that forgetting to buy etc. can be prevented and further purchase promotion can be promoted. .
この買い物リスト９９は、画像形成装置１が有する画像形成部が用紙に印刷してもいいし、画像形成装置１が有する通信部が買い物リスト９９のデータをユーザーのパソコンや携帯端末等に送信するようにしてもよい。 The shopping list 99 may be printed on paper by an image forming unit included in the image forming apparatus 1, or a communication unit included in the image forming apparatus 1 transmits data of the shopping list 99 to a user's personal computer, portable terminal, or the like. You may do it.
図３は、本実施の形態における購買支援処理の流れを説明したフローチャートである。図４及び図５は買い物リストの印刷例を示す図である。まず、画像読取部１３は、買い物メモを読み取る（ステップＳ２１）。尚、買い物メモが手書き、又は用紙に印刷されたものである場合のみ、画像読取部１３が買い物メモの読み取りを行う。買い物メモが文書データである場合は、ネットワークインターフェース部１９が外部装置３０からその文書データを取得し、画像読取部１３による読み取りは行わない。 FIG. 3 is a flowchart illustrating the flow of purchase support processing in the present embodiment. 4 and 5 are diagrams showing examples of shopping list printing. First, the image reading unit 13 reads a shopping memo (step S21). Only when the shopping memo is handwritten or printed on paper, the image reading unit 13 reads the shopping memo. When the shopping memo is document data, the network interface unit 19 acquires the document data from the external device 30 and the image reading unit 13 does not read the document data.
そして、画像読取部１３が買い物メモの読み取りを行った場合、文字認識部１１１は買い物メモの画像の文字認識を行って、認識した文字をデータ化する。文字抽出部１１２は、認識した文字からメモ物品名を示す文字列を抽出する（ステップＳ２２）。 When the image reading unit 13 reads the shopping memo, the character recognizing unit 111 performs character recognition of the shopping memo image and converts the recognized character into data. The character extraction unit 112 extracts a character string indicating the memo article name from the recognized characters (step S22).
次に、画像読取部１３は広告チラシを読み取って、広告画像を取得する（ステップＳ２３）。なお、本実施形態では、複数店舗分の広告チラシが画像読取部１３によって読み取られるものとする。尚、広告チラシが用紙に印刷されたものである場合のみ、画像読取部１３による広告チラシの読み取りが行われる。例えば電子広告等の画像データ化された広告である場合は、ネットワークインターフェース部１９が外部装置３０からその電子広告を取得することで上記広告画像が取得され、画像読取装置１３の読取による広告画像の取得は行われない。 Next, the image reading unit 13 reads an advertisement flyer and acquires an advertisement image (step S23). In this embodiment, it is assumed that advertisement leaflets for a plurality of stores are read by the image reading unit 13. Note that the advertisement leaflet is read by the image reading unit 13 only when the advertisement leaflet is printed on paper. For example, in the case of an advertisement converted into image data such as an electronic advertisement, the network interface unit 19 acquires the electronic advertisement from the external device 30 to acquire the advertisement image, and the advertisement image is read by the image reading device 13. Acquisition is not performed.
そして、文字認識部１１１が広告チラシの画像又は電子広告の文字認識を行って、認識した文字をデータ化する。文字抽出部１１２は、認識した文字から広告商品名を示す文字列を抽出する（ステップＳ２４）。 And the character recognition part 111 performs character recognition of the image of an advertisement flyer or an electronic advertisement, and converts the recognized character into data. The character extraction unit 112 extracts a character string indicating the advertisement product name from the recognized characters (step S24).
次に、文字検索部１１３は、ステップＳ２４で抽出された広告商品名からメモ物品名を含む広告商品名を検索する（ステップＳ２５）。例えば、メモ物品名として「牛乳」という文字がある場合、文字検索部１１３は、広告商品名から「牛乳」という文字を検索する。 Next, the character search unit 113 searches for the advertisement product name including the memo article name from the advertisement product name extracted in step S24 (step S25). For example, when there is a character “milk” as a memo article name, the character search unit 113 searches for a character “milk” from the advertisement product name.
尚、文字検索部１１３は、「牛乳」という文字が含まれている広告商品名を全て検索するため、例えば「フルーツ牛乳」や「牛乳寒天」等のユーザーの意図しない広告商品名を検索する場合もある。従って、文字検索部１１３がメモ物品名と全く同じ広告商品名のみを検索する（完全一致）、又はメモ物品名を含む全ての広告商品名を検索する（部分一致）の何れかを設定できるようにしてもよい。 Note that the character search unit 113 searches for all advertisement product names including the characters “milk”, and therefore, for example, searches for advertisement product names not intended by the user, such as “fruit milk” and “milk agar”. There is also. Therefore, the character search unit 113 can set either to search for only the advertising product name that is exactly the same as the memo article name (complete match) or to search for all the advertising product names including the memo article name (partial match). It may be.
更に、文字検索部１１３は、未抽出品記憶部１６１が記憶する未抽出文字、すなわち、過去にメモ物品名として検索されたが、広告掲載がなかったために検索されなかった未抽出文字を、広告画像（広告チラシ）の文字から検索する（ステップＳ２６）。 Further, the character search unit 113 advertises unextracted characters stored in the unextracted product storage unit 161, that is, unextracted characters that have been searched as memo article names in the past but have not been searched because no advertisement has been posted. A search is made from the characters of the image (advertisement flyer) (step S26).
続いて、商品情報取得部１１４は、メモ物品名を含む広告商品名の示す商品の商品情報（販売店舗名、価格、量、産地、付加特典等）を広告画像の文字（広告チラシに記載された文字）から取得すると共に、商品画像取得部１１５は、メモ物品名を含む広告商品名が示す商品の画像を、画像読取部１３によって取得された上記広告画像から抜き出す（ステップＳ２７）。 Subsequently, the merchandise information acquisition unit 114 describes the merchandise information (sales store name, price, quantity, production area, additional benefits, etc.) of the merchandise indicated by the advertising merchandise name including the memo article name in the character of the advertising image (advertisement flyer). The product image acquisition unit 115 extracts the product image indicated by the advertisement product name including the memo article name from the advertisement image acquired by the image reading unit 13 (step S27).
そして、リスト作成部１１６は、メモ物品名を含む広告商品名と、その商品の商品情報を掲載した図１に印刷例を示すような買い物リストを作成する（ステップＳ２８）。 Then, the list creation unit 116 creates a shopping list as shown in a print example in FIG. 1 in which the advertisement product name including the memo article name and the product information of the product are posted (step S28).
このとき、リスト作成部１１６は、例えば、文字検索部１１３によって検索された上記メモ物品名を含む広告商品名が複数あるときは、商品情報取得部１１４により取得される価格が低額である商品の広告商品名から順に並べて、図４に印刷例を示すような買い物リスト９９を作成するようにしてもよい。これにより、ユーザーは、買い物リストを視認したときに、最低額で商品を購入できる販売店舗を把握し易くなる。 At this time, for example, when there are a plurality of advertisement product names including the memo article name searched by the character search unit 113, the list creation unit 116 selects a product with a low price acquired by the product information acquisition unit 114. A shopping list 99 as shown in a print example in FIG. 4 may be created in order from the advertisement product name. Thereby, when the user visually recognizes the shopping list, the user can easily grasp the sales store where the product can be purchased with the minimum amount.
また、商品情報取得部１１４によって、広告商品名が示す同一の商品についての販売店舗名（文字「店」を含むワード）が複数取得されているときには、リスト作成部１１６は、当該複数の販売店舗名から予め定められた基準に従って選定した１つの販売店舗名及びその価格を示した買い物リストを作成するようにしてもよい。 When the product information acquisition unit 114 acquires a plurality of sales store names (words including the characters “store”) for the same product indicated by the advertisement product name, the list creation unit 116 displays the plurality of sales stores. You may make it produce the shopping list which showed one sales store name selected from the name according to the predetermined standard, and its price.
例えば、リスト作成部１１６は、上記予め定められた基準を、価格が最低額であることとして上記選定を行う。リスト作成部１１６は、図５に印刷例を示すような、商品毎に、最低額となる販売店を示した買い物リスト９９を作成する。これによれば、ユーザーは、多く掲載される販売店舗の中から、商品を最低額で購入可能な店舗を判別する作業が不要となり、また、買い物リストに掲載される販売店舗数も少なくなるのでユーザーが買い物リストをみたときの煩雑さが低減する。 For example, the list creation unit 116 performs the selection based on the predetermined standard as the price is the minimum amount. The list creation unit 116 creates a shopping list 99 indicating a store with the lowest price for each product, as shown in FIG. According to this, the user does not need to identify the store where the product can be purchased at the lowest price from among the many stores that are listed, and the number of stores that are listed on the shopping list is also reduced. The complexity when the user looks at the shopping list is reduced.
また、ステップＳ２５における文字検索部１１３の結果、広告チラシに掲載のなかったメモ物品名は未抽出文字として未抽出品記憶部１６１が記憶する（ステップＳ２９）。 Further, as a result of the character search unit 113 in step S25, the name of the memo article that has not been placed on the advertisement flyer is stored in the unextracted product storage unit 161 as unextracted characters (step S29).
以上、説明したように、広告商品名からメモ物品名を含む広告商品名を検索し、検索に挙げられた広告商品名が示す商品の価格や販売店舗名等の商品情報を用いてリスト作成部１１６が買い物リストを作成することで、ユーザーはその買い物リストを見れば、ある品物の複数店舗の販売情報を簡単に比較することができる。そして、リスト作成部１１６が買い物リストに価格、産地、付加特典の内容を記載することで、ユーザーはどの店で購入すべきかを判断しやすくなる。 As described above, an advertisement product name including a memo article name is searched from the advertisement product name, and a list creating unit is used by using product information such as the price of the product indicated by the advertisement product name and the store name indicated in the search. When the shopping list is created by the user 116, the user can easily compare the sales information of a plurality of stores of a certain item by looking at the shopping list. Then, the list creation unit 116 describes the price, the place of production, and the contents of the additional privilege in the shopping list, so that the user can easily determine which store to purchase.
また、文字検索部１１３の結果、広告チラシに掲載のなかったメモ物品名は未抽出品記憶部１６１が記憶し、後日別の広告チラシの文字認識が行われた際に、文字検索部１１３が未抽出品記憶部１６１の記憶する過去のメモ物品名を広告商品名から検索することで、広告掲載がなかったために購入しなかった商品を買い物リスト９９に載せることができ、買い忘れ等を防ぎ、更に購買促進を図ることができる。 In addition, as a result of the character search unit 113, the memo article name that has not been posted on the advertisement flyer is stored in the unextracted product storage unit 161, and when character recognition of another advertisement flyer is performed later, the character search unit 113 By searching for past memo article names stored in the unextracted product storage unit 161 from the advertisement product name, products that were not purchased because there was no advertisement posted can be placed in the shopping list 99, preventing forgetting to buy, etc. Furthermore, purchase promotion can be promoted.
