Other display information includes the resolution of the external display 10 and the like. The display information receiving unit 200 corresponds to the first receiving unit according to the present invention. The display information corresponds to display device information according to the present invention.

  The indexing processing unit 201 executes various processes related to indexing for searching for a target digital image from the image data 300 stored in the HDD 20. The result of the indexing process by the indexing processing unit 201 is stored as index information 301 in the database 20A.

  An indexing process executed by the indexing processing unit 201 will be described. For example, the indexing processing unit 201 performs grouping for each person shown in the image. First, a face area is detected from an image showing a person, and the detected face area is cut out from the image. For example, the detection of a face area is an area having features similar to feature data (referred to as a face image feature sample) obtained by analyzing image features and statistically processing the face image features of many persons. Can be done by searching. Assume that the face image feature sample is generated by classifying features based on the arrangement of eyes, eyebrows, nose, mouth, and the like in the face region. As described above, face image information is generated and stored in the index information 301 as a result of detecting a person in each image.

  Furthermore, the degree of front, size, and classification information may be included in the face image information by the indexing process executed by the indexing processing unit 201. The degree of front indicates the degree to which a face is photographed from the front in each face image extracted and stored by the indexing processing unit 201. The degree of photographing from the front is determined by the deviation from the position facing the front from the person, for example, based on the arrangement of eyes, eyebrows, nose, mouth, etc. in the face area. The size indicates the size of the face image area in the original still image in each face image. The classification information is obtained by classifying each face image according to images estimated to be the same person. The estimation of the same person is made, for example, from the degree of coincidence of the arrangement of eyes, eyebrows, nose, mouth, etc. in the face area.

  Also, the indexing processing unit 201 performs grouping by determining whether or not any character is captured from the image data 300, generates index information 301 using the determined result as character information, and stores the index information 301 in the index information 301. It is possible to promptly find out information for grasping the photographed situation, for example, the name of the party to be photographed, from the captured characters.

  The indexing processing unit 201 groups the plurality of image data 300 based on the shooting date and time, generates group information as a result of the determination, and stores the group information in the index information 301. The grouping is performed by separating a period between two image data 300 whose shooting dates and times are continuous over a predetermined period.

  Next, the configuration of the index information 301 generated by the indexing processing unit 201 will be described. The index information 301 includes an image ID, shooting date / time, face image information, character information, group information, and resolution information. The image ID is identification information uniquely assigned to the image data 300. The shooting date / time is time information indicating the shooting date / time of the image data 300. The face screen information is information indicating a person shown in the image data 300. The character information is information indicating whether or not a character appears in the image data 300. The group information is information grouped for each period based on the shooting date.

  If the index information 301 configured as described above is used, whether or not a person is photographed in the image data 300, which person is photographed, whether or not a character is photographed, and at what time the photograph is taken Can know. That is, it becomes possible to specify a person or to specify the image data 300 in which no person is shown, and it is possible to quickly find an image desired by the user. In the present embodiment, the image data 300 is selected using the index information 301. However, the image data 300 may be selected without using the index information 301. That is, an image group to be displayed may be selected by designating a folder in which the image data 300 is stored.

  The display image group setting unit 202 sets an image group for performing a slide show or a photo movie according to an operation from an input device such as the keyboard 5 or the touch pad 6. The setting of the image group is that the user selects the indexing process conditions (person, shooting time, etc.). The set image group corresponds to a display candidate image group according to the present invention. The display image group setting unit 202 reads the resolution of the image data 300 that matches the conditions set using the index information 301 and transmits the read resolution to the display control unit 203. The display image group setting unit 202 corresponds to the second receiving unit according to the present invention.

  The display control unit 203 refers to the display information received from the display information receiving unit 200 and the resolution of the image group received from the display image group setting unit 202, and displays the display form of the image data 300 output to the external display 10. decide. The display form of the image data 300 is whether or not the image data 300 is displayed in the first embodiment, and is the setting of the display size of the image data 300 in the second embodiment. Further, the display form of the image data 300 may include setting of an enlargement ratio when an effect of enlarging a part of the image data 300 is applied.

  First, a first embodiment according to the present invention will be described. In the first embodiment, the image data 300 determined to be appropriate to be displayed on the external display 10 is read from the HDD 20 and displayed on the external display 10 according to the flowchart shown in FIG. Further, the same content as that of the external display 10 may be displayed on the LCD 3a.

  Next, the procedure for selecting the image data 300 will be described with reference to FIG. FIG. 4 is a flowchart showing a procedure of display processing executed by the content reproduction application 101 in the first embodiment according to the present invention.

  First, the display information receiving unit 200 receives display information from the external display 10 (step S11). The display information receiving unit 200 receives display information from the external display 10 by transmitting a signal prompting the external display 10 to transmit display information including the display size.

  Next, the display control unit 203 determines the display resolution K1 on the external display 10 with reference to the received display information (step S12). This display resolution K1 is the minimum value of the resolution of the image displayed on the external display 10. That is, when an image having a resolution lower than the display resolution K1 is displayed on the external display 10, the image becomes too coarse due to enlargement, and it is difficult for the user to view. The display resolution K1 is determined by changing the size of the external display 10 and the resolution of the image to be displayed for verification.

  Next, the display image group setting unit 202 selects an image group to be displayed (step S13). That is, a group (a person, a scene, etc.) indexed by the indexing processing unit 201 is selected for selection. Alternatively, an image group is selected by designating a folder in which the image data 300 is stored.

  Next, the display image group setting unit 202 acquires the resolution K2 of one image data 300 included in the selected image group (step S14). That is, the display image group setting unit 202 reads the index information 301 related to the selected image group, and acquires the image resolution K2. When an image group is selected by designating a folder, the resolution K2 of the image data 300 stored in the folder is read.

  Next, the display control unit 203 determines whether or not the display resolution K1 determined in step S12 is equal to or higher than the image resolution K2 acquired in step S14 (step S15). That is, based on the image resolution K2 of the image data 300, it is classified into what is not displayed on the external display 10.

  As a result of the determination in step S15, when it is determined that the display resolution K1 is equal to or higher than the image resolution K2 (Yes in step S15), the image data 300 is determined as a display target (step S16). That is, when it is determined that the resolution of the image data 300 is sufficiently high and the user does not have difficulty in viewing even if the image data 300 is enlarged and displayed on the external display 10, the image data 300 is determined as a display target.

  On the other hand, when it is determined in step S15 that the display resolution K1 is less than the image resolution K2 (No in step S15), the image data 300 is excluded from the display target (step S17). In other words, since the resolution of the image data 300 is low, when it is determined that the image data 300 is difficult for the user to view when the image data 300 is enlarged and displayed on the external display 10, it is excluded from the display target.

  Next, the display control unit 203 determines whether there is unsorted image data 300 in the image group selected in step S13 (step S18). If it is determined in step S18 that there is unselected image data 300 (Yes in step S18), the process proceeds to step S14. That is, the determination is repeated for all the image data 300 included in the selected image group until the determination with reference to the resolution is completed.

  On the other hand, if it is determined in step S18 that there is no unselected image data 300 (No in step S18), the image data 300 determined as a display target is output to the external display 10 (step S19). The display processing procedure executed by the content reproduction application 101 is thus completed.

  In the above flowchart, after determining whether or not all the image data 300 included in the image group selected in step S13 is to be displayed, the image data 300 to be displayed is displayed on the external display 10. However, the present invention is not limited to this. That is, after determining whether or not the image data 300 is a display target, the image data 300 determined as the display target may be sequentially displayed. In this case, the determination as to whether or not the image data 300 is to be displayed and the display operation are performed in parallel.

  According to the first embodiment of the present invention configured as described above, when the resolution of the image data 300 is lower than that of the external display 10 and is difficult for the user to view, the display object is automatically selected. Therefore, comfortable viewing of the image can be realized without the need for sorting by the user.

  Next, a procedure for changing the display size of the image data 300 in accordance with the resolution will be described as a second embodiment of the present invention. FIG. 5 is a flowchart showing a procedure of display processing executed by the content reproduction application 101 in the second embodiment of the present invention. Steps similar to those in FIG. 4 are denoted by the same reference numerals, and description thereof is omitted.

  As a result of the determination in step S15, when it is determined that the display resolution K1 is equal to or higher than the image resolution K2 (Yes in step S15), the display control unit 203 determines the image data 300 as a target for full screen display (step S26). . On the other hand, as a result of the determination in step S15, when it is determined that the display resolution K1 is less than the image resolution K2 (No in step S15), the display control unit 203 determines that the image data 300 is to be reduced and displayed (step S15). Step S27). It is assumed that information regarding the reduction rate and the display position of the reduced image is stored in a storage device such as the HDD 20.

  Here, the display method of the image data 300 in this Embodiment is demonstrated using FIG. FIG. 6 is an example of an image display method according to the second embodiment of the present invention.

  FIG. 6A is a diagram showing a state in which the image data 300 is displayed on the external display 10 in full screen. FIG. 6B is a diagram illustrating a state in which the image data 300 is reduced and displayed on the external display 10. FIG. 6C is a diagram illustrating a state in which the image data 300 is reduced and displayed side by side on the external display 10.

  As shown in FIGS. 6B and 6C, when the resolution K2 of the image data 300 is low, the image data 300 is enlarged and displayed on the external display 10 when the image data 300 is displayed in a reduced size without being displayed on the full screen. Can be prevented from becoming difficult to watch. It is assumed that the reduction ratio and the number of image data 300 displayed on the external display 10 can be set by the user.

  Next, the display control unit 203 determines whether or not there is image data 300 whose display size has not been determined in the image group selected in step S13 (step S28). As a result of the determination in step S28, when it is determined that there is an image whose display size has not been determined (Yes in step S28), the process proceeds to step S14. On the other hand, as a result of the determination in step S28, when it is determined that there is no image whose display size has not been determined (No in step S28), the image data 300 is displayed at the reduction ratio determined for each image data 300 (step S29). . This is the end of the display processing procedure when the display size of the image data 300 executed by the content reproduction application 101 is changed.

  According to the second embodiment of the present invention configured as described above, when the resolution K2 of the image data 300 is lower than the display resolution K1 displayed on the external display 10, the image data 300 is set to a constant display size. It can be displayed. Therefore, the image data 300 can be displayed in a size corresponding to each image resolution K2 without displaying the low-resolution image data 300 on the external display 10 in full screen.

  In the second embodiment, the display size of the image data 300, that is, the enlargement ratio of the entire image data 300 is changed. However, the present invention is not limited to this, and a part of the image data 300 is enlarged. The same applies to the enlargement ratio when applying effects such as. In other words, an upper limit of the enlargement ratio corresponding to the image resolution K2 is set, and control is performed so that enlargement display exceeding the upper limit is not performed. Accordingly, even when an effect is applied to the image data 300, a part of the image having a low resolution is enlarged and displayed so that the image is coarsely displayed.
