In step S401, the CPU 201 performs a thumbnail image transmission process of display image data to be transmitted to the image display device 110 when the call is started after waiting for a call to start (step S401: Yes) (step S401: Yes). Step S402).

  A thumbnail image transmission process (step S402 shown in FIG. 4) in the image display apparatus 100 according to the embodiment of the present invention will be described with reference to FIG. FIG. 5 is a flowchart showing the contents of thumbnail image transmission processing (step S402 shown in FIG. 4) in the image processing apparatus according to the embodiment of the present invention. In the flowchart of FIG. 5, first, the CPU 201 extracts display image data presumed not to exist in the destination image display device 110 from the display image data stored in the storage medium 204 (step S501). ). The estimation as to whether or not it exists in the destination image display device 110 is associated with the file name 311 of each display image data in the table 310 indicating the display image data shown in FIG. 3 as history information, for example. Referring to the acquisition source 318, when the owner (telephone number) in the call history data or the phone book data does not match the owner (telephone number) of the destination image display device 110 with respect to the acquisition source device 318 Alternatively, it may be assumed that the image display device 110 of the transmission destination does not exist. In the description of FIG. 5, the table 310 is referred to in step S501. However, the present invention is not limited to this, and the display image data file name stored in the image display device 110 of the transmission destination is not limited to this. 311 may be queried to search for a match with the file name 311 of the display image data stored in the image display device 110.

  The CPU 201 performs importance level determination processing for thumbnail images generated from the image information 317 in the display image data extracted in step S501 (step S502).

  The importance level determination process (step S502 shown in FIG. 5) in the image display apparatus 100 according to the embodiment of the present invention will be described with reference to FIG. FIG. 6 is an explanatory diagram showing the contents of the importance determination process (step S502 shown in FIG. 5) according to the embodiment of this invention. In the flowchart of FIG. 6, first, the CPU 201 stores the call history data table 320 and the phone book data stored in the storage medium 204 based on the telephone number of the image display device 110 of the transmission destination where the call is started in step S401. Referring to the table 330, the keyword, the phone book, the previous call date and time, etc. associated with the telephone number of the image display device 110 are acquired from the call history data table 320 (step S601).

  The CPU 201 determines whether or not there is a previous call history associated with the telephone number 321 of the image display device 110 from the information acquired in step S601 (step S602). If there is no previous call history in step S602 (step S602: No), the process proceeds to step S607. If there is a previous call history in step S602 (step S602: Yes), the CPU 201 determines whether there is a place name in the keyword associated with the telephone number 321 in the call history data (step S603).

  If there is no place name in the keyword in step S603 (step S603: No), the process proceeds to step S605. If there is a place name in the keyword in step S603 (step S603: Yes), the CPU 201 converts the place name into latitude / longitude information, and the latitude / longitude associated with the file name 311 in the display image data table 310. Based on the information, weight is given to the display image data extracted in step S501 as the importance (step S604).

  As the weight, for example, a score determined by call history data and phone book data stored in the storage medium 204 and display image data is given. In step S <b> 604, the CPU 201 displays the image data for display stored in the image display apparatus 100 as the transmission source, with the latitude / longitude information converted from the keywords in the call history data associated with the image display apparatus 110 as the transmission destination. When the latitude / longitude information is within a predetermined range, a predetermined score is assigned to the display image data extracted in step S501.

  With reference to FIG. 7, description will be given of the assignment of weights as importance in the embodiment of the present invention. FIG. 7 is an explanatory diagram illustrating an example of determination items and points regarding weighting according to the embodiment of this invention. In FIG. 7, the weight list 700 includes a determination item and a score associated with the determination item.

  The determination items include items of call history data and phone book data associated with the image display device 110 (phone number) where the call is started in step S401 shown in FIG. 4, items of display image data, and The items to be compared are shown. The score is a weight to be given when a decision item is coincident or similar (approximate) within a predetermined range. Specifically, “the place name keyword of the call and the latitude / longitude of the image” are the latitude / longitude information based on the place name of the call history data shown in step S604, and the predetermined latitude / longitude information 313 of the display image data. This is an item for assigning “4 points” as a weight in the case of a range.

  “Keyword and image recognition” is an item that gives “2 points” as a weight when the image data for display includes the keyword 324 of the call history data by image recognition. The “keyword and image keyword” is an item to which “3 points” is given as a weight when the keyword 324 of the call history data and the keywords 314 and 415 of the display image data match or are similar.

  “Phone book face information and image recognition” is an item that gives “5 points” as a weight when face information 333 in the phone book data and face information 316 in the display image data match or are similar to each other. It is. The similarity is similar when, for example, a comparison is made with respect to a predetermined feature area between the face information 333 and the face information 316 and the difference is equal to or less than a predetermined value. “Telephone book keyword and image recognition” is an item that gives “2 points” as a weight when the image data for display includes the keyword 334 in the phone book data by image recognition. “Telephone book keyword and image keyword” is an item that gives “3 points” as a weight when the keyword 334 in the phone book data and the keywords 314 and 415 in the display image data match or are similar to each other. It is.

  The “display count of 10 times or more” is an item for giving “3 points” when the display count 312 of the display image data is 10 times or more. That is, for example, the sum of the weights of the display image data in which “the place name keyword of the call and the latitude / longitude of the image” and “the face information in the phone book and the image recognition” are the same or similar and the number of display times is 10 or more “12 points”.

  Returning to FIG. 6, the CPU 201 performs weighting by the keyword 324 in the call history data (step S605). The weighting by keyword is given by, for example, “keyword and image recognition” or “keyword and image keyword” shown in FIG.

  The CPU 201 performs weighting according to the number of display times from the previous call to the current call (step S606). The weighting by the number of display times is given by, for example, “10 times or more of the number of display times” shown in FIG. In step S606, the number of displays in the period from the previous call to the current call is used, but the present invention is not limited to this. Specifically, the total display count, the display count for a predetermined period, or the like may be used.

  The CPU 201 registers the phone book of the destination image display device 110 (the phone number) from which the call was started in step S 401 shown in FIG. 4 from the phone book data table 330 in the information acquired in step S 601. Whether or not (step S607). In step S607, when there is no telephone directory registration (step S607: No), a series of importance determination processing ends as it is, and the process proceeds to step S503 shown in FIG.

  In step S607, when the phone book is registered (step S607: Yes), the CPU 201 determines whether or not face information is registered in the face information 333 of the phone book data (step S608). If no face information is registered in step S608 (step S608: No), the process proceeds to step S610.

  In step S608, when face information is registered (step S608: Yes), the CPU 201 performs weighting by face authentication (step S609). The weighting by the face authentication is given by, for example, “face information and image recognition in the phone book” shown in FIG.

  The CPU 201 performs weighting by keywords such as hobbies in the telephone directory data (step S610), ends the series of importance determination processes as it is, and proceeds to step S503 shown in FIG. Weighting by keywords such as hobbies is given by, for example, “phonebook keywords and image recognition” or “phonebook keywords and image keywords” shown in FIG.

  In the description of FIGS. 6 and 7, the configuration is described in which weights are assigned to each item of the display image data and each item of the call history data and the phone book data with respect to the determination item. There is no. Specifically, when a keyword is used, a weight may be given in comparison with the conversation content with the destination image display device 110. Further, when there is a match or similarity between a plurality of items, the weight may be adjusted to be higher. Moreover, you may provide a score in multiple steps about a decision item. For example, regarding the number of display times, 0 to 4 times may be 0 points, 5 to 9 times may be 1 point, and 10 times or more may be 3 points. Regarding the keyword, the weight may be changed depending on the number of appearances of the keyword. By doing in this way, the importance can be determined with high versatility and high accuracy.

  Returning to FIG. 5, the CPU 201 performs the layout determination process for the thumbnail image generated from the image information of the display image data based on the importance determined in step S502 (step S503).

  The layout determination process (step S503 shown in FIG. 5) in the image display apparatus 100 according to the embodiment of the present invention will be described with reference to FIG. FIG. 8 is a flowchart showing the contents of the layout determination process (step S503 shown in FIG. 5) in the image display apparatus according to the embodiment of the present invention. In the flowchart of FIG. 8, first, the CPU 201 generates a thumbnail based on the importance determined in step S502 in order to determine the size and order of the thumbnail images based on the importance determined in step S502. The display image data is rearranged in descending order of importance (step S801).

  The CPU 201 determines the thumbnail image size to be either large, medium, or small based on a predetermined threshold for the display image data rearranged in step S801 (step S802). The size of the thumbnail image may be determined according to the size of the display 215, for example. Specifically, for example, among the sizes, “Large” is a size that can display 4 images on one page (one screen), “Medium” is a size that can display 9 images on one page, and “Small” is 1 page. This is the size that can display 16 images. The predetermined threshold value may be determined by, for example, a weight assigned as the importance level. Specifically, if the importance is 15 points or more, it is “large”, if the importance is 8 to 14 points, “medium”, if the importance is 3 to 7 points, “small”, and the importance is 3 If it is less than the number of points, thumbnails are not created.

  For each size of the thumbnail image determined in step S802, the CPU 201 determines the number adjustment and arrangement of each size for display (step S803), ends the series of layout determination processing, and performs the steps shown in FIG. Return to S505. The number adjustment and the determination of the arrangement are determined, for example, according to the quantity of display image data for which thumbnails are to be generated and the number of images that can be displayed on one page of each size.

  The adjustment of the number of thumbnail images and the determination of the arrangement in the image display apparatus according to the embodiment of the present invention will be described with reference to FIG. FIG. 9 is an explanatory diagram showing an example of adjusting the number of thumbnail images and determining the arrangement in the image display apparatus according to the embodiment of the present invention. In FIG. 9, the thumbnail images of the 14 display image data in the size and order determination process shown in FIG. 8 are determined as “large” size 1 sheet, “medium” size 5 sheets, and “small” size 8 sheets. The case will be described.

  Since “Large” size can display 4 images per page, 2 images, 4 images, and 6 images (4 images per page + 2 images on other pages) are displayed in multiples of 2. When displaying, it is set as the structure displayed in parallel in the length or width of 1 page. Since the “medium” size can display 6 images on one page, it should be displayed in multiples of 3, such as 3, 6, 9 (6 on 1 page + 3 on other pages). When displaying, it is set as the structure displayed in parallel vertically or horizontally. In the example of FIG. 10, a case where both the “large” size and the “medium” size are displayed vertically in parallel will be described.

  The “small” size is displayed in the margin after the arrangement of the “large” and “medium” sizes. In the case of the arrangement as described above, fine adjustment is performed from the size and order ratio shown in FIG. 8, and the number adjustment and arrangement of each size are performed so that the thumbnail image lists 901 and 902 shown in FIG. 9 are obtained. It will be.

  Returning to FIG. 5, the CPU 201 generates a thumbnail image of the display image data based on the number and arrangement of the sizes of the thumbnail images determined in step S <b> 803, and converts the generated thumbnail image into the communication I / F 207. Is transmitted to the destination image display device 110 (step S505), a series of thumbnail image transmission processing is terminated, and the process returns to step S403 shown in FIG.

  Returning to FIG. 4, the CPU 201 determines whether or not the call started in step S <b> 401 has ended (step S <b> 403). In step S403, the CPU 201 waits for the call to end, and when the call ends (step S403: Yes), the CPU 201 updates the call history data as the history information stored in the storage medium 204, and returns to step S401. .

(Contents of processing of image display device 110)
The contents of the processing of the destination image display apparatus 110 according to the embodiment of the present invention will be described with reference to FIG. FIG. 10 is a flowchart showing the processing contents of the destination image display apparatus according to the embodiment of the present invention. The flowchart in FIG. 10 is a flowchart illustrating an example of processing in which the image display device 110 receives a thumbnail image from the image display device 100 that is a terminal device that is the transmission source of display image data.

  In the flowchart of FIG. 10, first, the CPU 201 determines whether or not a call with the image display apparatus 100 is started via the communication I / F 207 (step S1001). Specifically, a call signal transmitted from the transmission source image display apparatus 100 via the provider connected to the network 150 is received by the communication I / F 207. In step S <b> 1001, the CPU 201 determines that a call has been started when an incoming call is made according to the call signal received by the communication I / F 207. In step S1001, the CPU 201 waits for a call to start and, if started (step S1001: Yes), whether the CPU 201 has received a thumbnail image of image data for transmission display from the image display device 100 that is the transmission source. Is determined (step S1002).

  In step S1002, the CPU 201 controls the video I / F 205 and displays the thumbnail image received in step S1002 on the display 215 after waiting for the thumbnail image to be received (step S1002: Yes). (Step S1003).

  CPU201 judges whether the telephone call started in step S1001 was complete | finished (step S1004). In step S1004, the CPU 201 updates the call history data as history information stored in the storage medium 204 (step S1005) after waiting for the call to end and when the call ends (step S1004: Yes). The process returns to step S1001.

  Although not described in the flowchart of FIG. 10, the thumbnail images displayed in step S1003 are displayed in a list so as to be selectable in order to request acquisition of display image data from which thumbnail images are generated. It is. That is, when the user of the image display apparatus 110 selects display image data desired to be acquired from the list of thumbnail images, the CPU 201 makes an acquisition request to the image display apparatus 100. The transmission source image display device 100 is configured to transmit the display image data from which the selected thumbnail image is generated when an acquisition request is received from the transmission destination image display device 110. For example, the display image data acquisition request may be made not only during a call but also at a timing after the call. That is, the thumbnail image displayed in step S1003 may be configured to be displayed by a user operation after the call ends.

  As described above, according to the display image device of the embodiment of the present invention, the thumbnail image of the display image data to be a transmission candidate (reception candidate) is generated based on the call history data and the phone book data. Can do. Also, the size and arrangement of thumbnail images can be appropriately determined based on call history data and phone book data. Therefore, the transmission destination user can efficiently select desired display image data. In addition, the display image data desired to be transmitted by the transmission source user and the desired display image data of the transmission destination user without transmitting the display image data from the transmission source image display device. Therefore, display image data can be appropriately selected while reducing the communication amount.

(Other variations)
In the embodiment of the present invention, in particular, the size of the thumbnail image is determined based on a predetermined threshold in step S803 shown in FIG. 8, but the present invention is not limited to this. Specifically, for example, instead of using a threshold for the score given as the importance, a ratio of each size of “large”, “medium”, and “small” is determined, and based on the determined ratio, A configuration may be used in which each size of the thumbnail image is determined from a high degree.

  The predetermined size may be based on a size that can be displayed on one page of the list displayed on the display 215, for example. That is, when “Large” can display 4 images per page, “Medium” can display 9 images per page, and “Small” can display 16 images per page, Large: Medium: Small = 4: 9 : 16 may be determined. In this way, the size of the thumbnail image can be appropriately determined without performing a comparison process using a predetermined threshold.

  Moreover, the structure which determines the ratio of each size according to the whole number of sheets may be sufficient. Specifically, when the total number of sheets is 1000 or more, the ratio of the “large” size is reduced, and many “medium” and “small” size thumbnail images are generated. In this way, a list of thumbnail images can be efficiently confirmed.

  In the embodiment of the present invention, the thumbnail image size is determined based on a predetermined threshold. However, the present invention is not limited to this. Specifically, for example, each size may be changed according to the ratio of the “large” size. For example, when the ratio of the “large” size is less than 5% of the whole, or when the number of pages displayed in the “large” size is less than the predetermined number of pages, the size of the “large” size is large. It is good also as extending. When the “large” size is determined so that four images can be displayed on one page, when a predetermined ratio such as less than 5% of the whole or the number of pages displayed in the “large” size is less than the predetermined number of pages In this case, the size of the “large” size is changed to one size per page. On the other hand, when the ratio of the “large” size is a predetermined ratio such as 50% or more of the whole, or when the number of pages displayed in the “large” size is more than the predetermined number of pages, the “large” size is large. It is also possible to reduce the size. By doing so, it is possible to optimize the layout determination of thumbnail images.

  Further, in the embodiment of the present invention, in particular, the configuration is such that the importance level determination process in step S502 and the layout determination process in step S503 shown in FIG. 5 are performed by the image display apparatus 100 of the transmission source. . Specifically, for example, after generating the transmission target thumbnail image, the transmission source image display apparatus 100 associates the generated thumbnail image with each item of the display image data and transmits it to the transmission destination image display apparatus 110. . When the destination image display device 110 receives a plurality of thumbnail images, the CPU 201 performs an important function based on the call history data and the phone book data stored in the storage medium 204 of the own device as a function of the creation unit of the present invention. It may be configured to execute the degree determination process and the layout determination process.

  Further, the configuration up to the importance level determination process shown in FIG. 5 may be performed by the transmission source image display apparatus 100, and the layout determination process may be performed by the transmission destination image display apparatus 110. Of course, both the image display apparatuses 100 and 110 may be configured to perform importance level determination processing or layout determination processing. Furthermore, the configuration may be such that the importance determination process and the layout determination process are performed by an apparatus having high processing performance depending on the processing performance of the image display apparatuses 100 and 110. Specifically, for example, the CPU 201 of the transmission source image display apparatus 100 implements the function of the performance acquisition unit of the present invention, and acquires the performance information of the transmission destination image display apparatus 110 via the communication I / F 207. Further, the CPU 201 of the image display measure 110 of the transmission destination acquires the performance information of the own device. By doing in this way, the versatility of the whole system can be improved and the convenience can be improved.

  Further, the thumbnail image based on the layout information determined in step S503 is transmitted to the image display device 110 as the transmission destination in step S505. However, the present invention is not limited to this. Specifically, for example, the transmission source image display apparatus 100 transmits the layout information determined in step S503 and the thumbnail image based on the display image data by the process of step S505. The destination image display apparatus 110 receives a plurality of thumbnail images and layout information through the processing in step S1002. The destination image display device 110 may display a list of the received thumbnail images based on the layout information.

  Further, in the embodiment of the present invention, in particular, in step S501 shown in step S501, display image data that is a generation source of a thumbnail image to be transmitted is extracted, and therefore a display that does not exist in the destination image display device 110 is displayed. However, the present invention is not limited to this. Specifically, for example, as in the importance level determination process shown in step S502, using the call history data and the phone book data, the upper predetermined number of image data is extracted from the display image data with high importance level. Also good. In this way, display image data with high importance can be accurately extracted, and a thumbnail image of display image data desired by a transmission destination user can be efficiently transmitted.

  In the embodiment of the present invention, the thumbnail image transmission process shown in FIG. 4 (step S505 shown in FIG. 5) has been described as being performed during a call in steps S401 to S403. However, the present invention is not limited to this. There is no. Specifically, for example, when the transmission of the thumbnail image to be transmitted is not completed even after the call is terminated, the transmission may be continuously performed. At this time, the same applies to the reception and display of thumbnail images in steps S1002 and S1003 shown in FIG. Specifically, the thumbnail image may be received even when the call ends in step S1004. In this way, it is possible to reliably transmit thumbnail images. Further, when the call time is short, the thumbnail image may not be transmitted. In this way, communication can be optimized without performing transmission / reception of thumbnail images, for example, when the purpose is only a telephone call.

  Further, in the embodiment of the present invention, the content of the previous call is used as the call history data shown in FIG. 3, but the present invention is not limited to this. Specifically, for example, the content of the current call may be used as call history data. When using the contents of the current call, the thumbnail image transmission process through the importance determination process, the layout determination process, and the like is a process after the call ends. If the content of the current call is used as a keyword, thumbnail images can be transmitted and received with the latest importance for the user.

  Further, in the embodiment of the present invention, in particular, the importance and the predetermined threshold value are used in the determination of the size and order in step S801 and step S802 shown in FIG. 8, but the present invention is not limited to this. Specifically, for example, the resolution of the display 215 may be acquired as the performance information of the destination image display device 110, and the size and order may be determined using the acquired resolution. Specifically, regarding the minimum resolution of the preset “small” size thumbnail image, the “small” size is set so that the resolution of the thumbnail image of the “small” size does not fall below the minimum resolution from the resolution of the display 215. This is a configuration to be determined.

  More specifically, for example, when the minimum resolution of the “small” size is 140 × 105 pixels and the resolution of the display 215 is 640 × 480, the thumbnail image of the “small” size exceeds the display 215. If there is no range, horizontal: 140 × 4 = 560, vertical 105 × 4 = 420, 16 sheets. The resolution of the display 215 of the transmission destination image display apparatus 110 is acquired together with the start of the call in step S401 shown in FIG. 4, for example, or an acquisition request is sent from the transmission source image display apparatus 100 to the transmission destination image display apparatus 110. It is good to do.

  In the embodiment of the present invention, the telephone call using the IP telephone has been described. However, the present invention is not limited to this. Specifically, for example, the present invention may be applied to a case where a telephone call is made through an exchange using a public telephone line network. Further, for mail transmission / reception using the Internet, a mail transmission / reception history or a mail address may be used. In this way, resistance can be improved.

  In the above description, the embodiment and some of the modifications have been described as separate examples, but the present invention is not limited to this. That is, as a combination of the above, the methods according to the embodiment and some modifications may be used in appropriate combination.
