Description

  The present invention relates to an image display device for displaying an image, and more particularly to an image display device that displays an image associated with a sentence such as a diary text.

  In recent years, so-called blogs (blog: abbreviation of weblog), which are easier to create than homepages, have become popular. There are also various ideas that make this blog easier to use.

  For example, many blogs are displayed in order from the newest uploaded content, and the appearance is similar to a diary. However, a system has been proposed that allows users to easily create such a blog as if they had a daily diary. Various services using these systems are also available.

  By the way, for example, when a person who has traveled to a place has traveled to the place for the first time in a long time, and the land has changed due to development work, it may be disappointed. It was. In such a case, it is conceivable that the user knows in advance that the landscape will change and wants to visit the land and take a picture before the landscape changes. As a technique related to shooting according to such a change in scenery, for example, in Patent Document 1, images of each work process at a construction site are obtained by shooting the construction site in the order according to the construction schedule information. Have acquired. Thereby, it is possible to obtain an image according to the change of the construction site in each work process according to the work procedure.

Also, even if there is no major change like land development, if there are events such as autumn leaves or festivals of the land, if you are attached to the land, you will want to go to the land It is possible to be deaf. As a technology related to the distribution of such land information, for example, in Patent Document 2, various types of information on the land that the individual is interested in can be distributed to the individual.

If the place name search target is the text file, a good impression is described in the text, or the date associated with the text file Information is that shown one of holidays and vacations, if the search target of the place name is the image file, characterized in that it is a case that contains the image with good expression in the image.

  According to the present invention, it is possible to provide an image display device that appropriately distributes memorable land information to the user and makes the user feel like going to the land again.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of an image display system including an image display device according to an embodiment of the present invention. The image display system shown in FIG. 1 includes a server 1 having a function as an image display device according to an embodiment of the present invention, a search site 2, and a personal computer (PC) 3. And are connected to each other through data communication. In addition, a digital camera 5 is connected to the PC 3 so as to be able to perform data communication, and an image file obtained by photographing with the digital camera 5 can be transmitted from the PC 3 to the server 1 via the network 4.

  The server 1 includes a communication unit 11, a recording unit 12, an important place name recording unit 13, and an information display control unit 14.

The communication unit 11 performs communication control when the server 1 communicates with the search site 2 and the PC 3.
The recording unit 12 includes a content recording unit 12a and a place name recording unit 12b. The content recording unit 12a records content including a text file such as a diary and an image file transmitted from the digital camera 5 in association with the creation date. The place name recording unit 12b extracts place name information from the content recorded in the content recording unit 12a, and organizes and records the extracted place name information for each date associated with the content.

  The important place name recording unit 13 has a preference database 13a. From the information recorded in the preference database 13a, etc., the place name of the place that the user has attached to among the place names recorded in the place name recording unit 12b ( (Hereinafter referred to as “important place name”) is extracted and recorded. Further, an article is searched by accessing the search site 2 using this important place name as a search keyword, and important event information related to the important place is acquired from the searched article and recorded.

  The information display control unit 14 performs control when displaying the content recorded in the content recording unit 12a on the display of the PC 3. The information display control unit 14 also performs control when displaying event information related to the important place according to a predetermined condition.

  The search site 2 searches for articles related to important place names using the important place names extracted by the important place name recording unit 13 as search keywords.

  The PC 3 is a general computer having a display for browsing a web page and various operation units such as a mouse and a keyboard for performing various operations on the web page.

  The digital camera 5 shoots a subject and creates an image file. The configuration of the digital camera 5 is not particularly limited, but if the digital camera 5 has a GPS function, position information of important place names can be attached to the image file. Note that the digital camera 5 is not necessarily used as long as the image file can be input to the PC 3 or the server 1.

  In the image display system as described above, when the user sends an image file and a text file from the PC 3 to the server 1, the image file and the text file are received by the communication unit 11 of the server 1. Thereafter, the received image file and text file are recorded in the content recording unit 12a. If the digital camera 5 has a function of connecting to the network 4, the image file can be directly transmitted from the digital camera 5 to the server 1.

  Here, in the present embodiment, shooting date (date and time) information is recorded in, for example, a header portion of an image file obtained by the digital camera 5. A text file created by the PC 3 is also described in a format including a date such as a diary format. In addition, when the place name of the land shown in the image file can be specified (for example, using the GPS function) or the place name is included in the document file, the place name information specified by the place name is displayed for each date. Recorded in the recording unit 12b.

  The important place name recording unit 13 has a place name that appears many times in the text, a place name that is regularly photographed, and an attachment in the document file or image file recorded in the content recording unit 12a. The place names considered to be important place names are extracted and recorded. Whether the place name is attached or not is determined using the preference database 13a. In the preference database 13a, good impression texts indicating that the land has a good impression, such as “fun”, “joyful”, “feeling good”, “nostalgic”, etc. are recorded. In determining whether or not the name is an important place name, it is determined that the user is attached to the place when the document file includes a good impression text together with the place name.

  For example, when a blog article (diary text with an image) as shown by reference numeral 101 in FIG. 2 is created by the user, the contents of the article are determined from the article creation date “January 20” and the text “Yesterday”. Can be seen on January 19th. In addition, since the place name text “May Drink” and the good impression text “Fun” are included, the experience at that time is enjoyable by the user, and the place “May Drink” is attached to the user. It is determined that it is an important place. These determination results are managed for each date, for example, in a format indicated by reference numeral 102.

  Further, as a method for determining an important place name, a land visited at a specific time such as “summer vacation” or “winter vacation” may be determined as an important place name. Further, when a person is shown in the image, it may be determined from the facial expression of the person whether or not the image becomes a memory.

  When an important place name is extracted by various methods as described above, a search is performed on the search site 2 using the extracted important place name as a search keyword, and important event information in the important place is acquired. The important event information acquired here is displayed on the PC 3 according to a predetermined condition. This predetermined condition will be described later.

  FIG. 3 is a flowchart showing the control executed by the server 1. In FIG. 3, the server 1 determines whether content including an image file or a text file has been input from the PC 3 or the digital camera 5 (step S1). When content including an image file or a text file is input in step S1, the input content is recorded in the content recording unit 12a (step S2). Thereafter, the server 1 determines whether or not the place name can be specified from the input content (step S3). For example, in the case of an image file, determination is made based on whether or not place name information (or shooting position information) measured by GPS is included. In the case of a sentence file, the determination is made based on whether or not a place name text is included as shown in FIG. If it is determined in step S3 that the place name cannot be specified from the input content, the server 1 ends the process of FIG.

  On the other hand, in the determination of step S3, when the place name can be specified, the server 1 records the place name thus specified in the place name recording unit 12b in association with the date (step S4). Next, the server 1 determines whether or not a good impression text is included in the content input by the user (step S5). In the determination in step S5, if the content does not include a good impression text such as “fun”, “joyful”, “feeling good”, “nostalgic”, etc. (including content only of image files), the server 1 Then, it is determined whether or not the content entered by the user is on a day corresponding to a holiday or a vacation (a vacation is set in advance by the user) (step S6). If it is determined in step S6 that the content is not for a day corresponding to a holiday or vacation, the server 1 determines whether or not the facial expression of the person in the image in the content input by the user is good. Determination is made (step S7). If it is determined in step S7 that the facial expression of the person in the image is not good (including the case of content of only a text file), the server 1 ends the processing shown in FIG.

  Here, the facial expression determination in step S7 will be described. FIG. 4 is a flowchart showing details of a favorable facial expression determination process. In FIG. 4, first, the server 1 detects an eye part and a mouth part in the face part in the image from the shadow distribution in the image (step S <b> 101). More specifically, a face part that is substantially circular in the image with the contrast of the image being emphasized is detected, and the eye part and the nose part are detected from the distribution of shadows in the face part.

  After detecting the eyes and nose in step S101, the server 1 obtains the area EA (see FIG. 5A) of the white-eye portion above the straight line A connecting the eyes of both eyes (step S102). Next, the server 1 obtains the area EB (see FIG. 5A) of the white-eye portion below the straight line A connecting the eyes of both eyes (step S103). After obtaining EA and EB, the server 1 obtains a value RE obtained by normalizing the difference between EA and EB by the sum of EA and EB (step S104). Here, in the case of a smile, since EB is close to 0 as shown in FIG. 5A, the result RE increases. On the other hand, in the case of a troubled face, the EA becomes close to 0 as shown in FIG. Therefore, it is possible to determine whether the expression is good or not from the magnitude of RE.

  After obtaining the RE, the server 1 obtains the area LA (see FIG. 5B) of the upper lip portion of the straight line B connecting both ends of the mouth (step S105). Next, the server 1 obtains an area LB (see FIG. 5B) of the lower lip portion of the straight line B connecting both ends of the mouth (see FIG. 5B). After obtaining LA and LB, the server 1 obtains a value RL obtained by normalizing the difference between LB and LA by the sum of LA and LB (step S107). Here, in the case of a smile, since LA is close to 0 as shown in FIG. 5A, the result RL increases. On the other hand, in the case of a troubled face, LB becomes small as shown in FIG. Therefore, it is possible to determine whether or not the expression is a good expression from the size of RL.

  After obtaining RE and RL, the server 1 obtains the sum R of RE and RL (step S108). The larger R is, the closer the expression at that time is to a smile (good expression). Furthermore, as shown by the arrow C in FIG. 5 (a), if there is a shadow on the edge of the mouth or teeth are visible, the probability of smile is high. Therefore, the server 1 determines whether a tooth (white portion) is detected in the mouth portion and whether there is a shadow on the mouth end portion (step S109). If it is determined in step S109 that teeth are detected in the mouth portion and there is a shadow on the mouth end, the server 1 adds 1 to R (step S110).

  On the other hand, if it is determined in step S109 that teeth are detected in the mouth portion and there is no shadow at the mouth end portion, or after step S110, the server 1 indicates the portion between the eyebrows (the portion between the eyes) with an arrow D. It is determined whether there is a wrinkle (step S111). If it is determined in step S111 that the eyebrow has a wrinkle, the server 1 subtracts 1 from R (step S112). That is, a facial expression in which a wrinkle is detected between the eyebrows cannot be said to be a smile, so the determination in step S111 is performed.

  R obtained as described above becomes a higher value as it is closer to a smile. With this R, it is possible to determine whether or not the expression of the human subject in the image is good. That is, after step S111 or step S112, the server 1 determines whether or not the value of R is greater than or equal to a predetermined value (here, 2) (step S113). If it is determined in step S113 that R is 2 or more, the server 1 determines that the facial expression of the person is a good facial expression (step S114). On the other hand, if it is determined in step S113 that R is less than 2, the server 1 determines that the facial expression of the person is not a good facial expression (step S115). After step S114 or step S115, the process of FIG. 4 is exited. There may be a case where a plurality of persons exist in the image. In this case, for example, R for the number of persons in the image may be obtained, and an image with a good expression may be determined when R for a majority of persons is equal to or greater than a predetermined value.

  Here, it returns to description of FIG. 3 again. If the favorable impression text is included in the content in the determination in step S5 of FIG. 3, the content of the content is for a day corresponding to a holiday or vacation in the determination in step S6. When the facial expression of the person is good, the server 1 sets the place name recorded in step S4 as the important place name (step S8), and sets the date associated with the important place name as the important date (step S9). ). Thereafter, the server 1 ends the process shown in FIG.

  If no content is input in the determination in step S1, the server 1 determines whether a predetermined period (for example, one day or one week) has elapsed (step S10). When the predetermined period has passed in the determination in step S10, the server 1 searches the article by accessing the search site 2 using the important place name set in step S8 as a search keyword (step S11). After the article search ends, the server 1 determines whether there is important event information in the searched article (step S12). In the determination in step S12, when the searched article includes important event information such as autumn leaves information, land development information, festival information, etc., the server 1 records the event information in the important place in step S2. For example, the content is displayed on the display of the PC 3 as shown in FIG. 6 (step S14). Thereafter, the server 1 ends the process of FIG.

  For example, FIG. 6 shows a case where construction is performed in an important place, and information indicating that construction is performed when such an article is searched using the search site 2. 201 and content 202 created by the user regarding the important place are displayed on the PC 3. The construction development plan information as shown in FIG. 6 may change the nostalgic scenery for the user, so the user may miss the past and may want to go back to the land before the scenery changes. To do.

  Here, the important event information shown in FIG. 6 may be displayed only once when the PC 3 is powered on after the acquisition of the important event information, or the important event is performed. Until then, it may be displayed periodically.

  If there is no important event information in the searched article in the determination in step S12, the server 1 determines whether the important date determined based on the important date has come (step S13). This important date is a date after a predetermined date (for example, 20 days) after the same date (ie, one year later, two years later,...) As the date that was converted to the important date in step S9. If the important date is reached in the determination in step S13, the server 1 displays information indicating that the important date is approaching on the display of the PC 3 together with the content recorded in step S2 (step S14). Thereafter, the server 1 ends the process of FIG. In this way, for example, it is possible to view images taken at the entrance ceremony every year. As a result, the user can remember a nostalgic image and immerse himself in the feeling of nostalgia.

  If the predetermined period has not elapsed in the determination in step S10, the server 1 determines whether or not a content reproduction instruction has been issued by the user (step S15). If it is determined in step S15 that no content reproduction instruction has been issued, the processing in FIG. 3 ends. On the other hand, when the content reproduction instruction is given in the determination in step S15, the server 1 reproduces the content selected by the user on the PC 3 (step S16). Thereafter, the process of FIG. 3 is terminated.

  As described above, according to the present embodiment, even if the user does not bother to spend time searching for event information, content related to a land having an important event is searched, and the searched content is searched at an appropriate timing. It can be presented to the user. By showing the presented contents in this way, it is possible to make the user nostalgic and want to go to the land again. Also, because important event information is presented before the event actually takes place, it is possible to reduce the possibility of disappointing the user when the user goes back to the land and the scenery changes. is there.

  Although the present invention has been described above based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications and applications are naturally possible within the scope of the gist of the present invention.

  Further, the above-described embodiments include various stages of the invention, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements.
