Description

  The present invention relates to an image display control apparatus that stores a plurality of images and reproduces and displays an image selected so that a desired image can be selected from a selection image displayed in a list.

  There is a so-called electronic album apparatus that records and manages a plurality of images on a recording medium and reproduces and displays them at a desired time. Such an electronic album device is connected to a television receiver via a video cable or the like in the same manner as a conventional VTR and displays a reproduced image on the screen, but the electronic album device is connected to the television receiver via a cable. When the electronic album apparatus is activated, there is one having a function of automatically displaying a reproduced image on a television screen (see, for example, Patent Document 1).

  On the other hand, on screens of television receivers (hereinafter referred to as TV screens), so-called wide screens with an aspect ratio of 16: 9 are widespread in addition to those with an aspect ratio of 4: 3, but in digital cameras and mobile phones with cameras, An aspect ratio of 4: 3 is the mainstream. This is because the image pickup device does not support a wide screen, so it is meaningless to enlarge only the display.

  Therefore, an image taken with a digital camera or a camera-equipped mobile phone is temporarily recorded in the electronic album device, and the desired image is obtained from the electronic album device by connecting the electronic album device to a television receiver widely used at home. If it is sent and displayed, the electronic album device does not have to have a display device, and the user can take an image taken with a digital camera or the like on a television screen having a larger screen size than the digital camera at intervals of turning the album. It is possible to display.

In addition, in order to reproduce a desired image among images recorded on a recording medium, it is necessary to check the contents of a plurality of frame images recorded on the recording medium. An image display method is known in which images are indexed on the display, and all frames are checked while scrolling the frame index screen to search for frame images. However, the number of images recorded on a large-capacity recording medium is known. An image display device has been proposed that narrows down the frames included in the frame index screen using the shooting time as a narrowing condition before displaying the frame index screen because it is inappropriate for searching for a thousand frame images. (For example, refer to Patent Document 2). In this patent document, the shooting time is specified on the specified period selection screen (year, month, day) at a level lower than the specified period ("month" if the specified period is year, "day" if "month"). ) One representative frame (thumbnail image) is displayed in the unit area classified by), and prompts specification (selection) (in this case, the representative frame is sequentially switched and displayed as a slide show), and a desired frame is specified. Is disclosed. Further, it is disclosed that the representative frame can be set to the head screen, the tail screen, or arbitrarily set, and the image volume (number of recordings) of each group is displayed.

When the list display screen data (video data) adapted to the 4: 3 TV screen is sent to the TV side, the list display screen size does not appear in a wide-screen TV receiver with an aspect ratio of 16: 9. The list display screen displayed on the TV screen lacks balance and the display area cannot be used effectively. If it is configured to send the list display screen data (video data) that matches the 6: 9 TV screen to the TV receiver, the list display screen is too large for a wide screen TV receiver with an aspect ratio of 4: 3. There is a problem that part or all of the list display screen is not displayed. In the latter case, even if the list display screen is reduced and displayed, the aspect ratio of the TV screen cannot be known on the electronic album side, so the list display screen cannot be reduced to fit the screen size. Even if the reduced display is possible, the reduced image displayed on the list display screen is further reduced, which makes it difficult to view.

An image evaluation value storage column 69 is provided.

  Of the above-described storage columns, the title to time intervals stored in the title storage column 62 to the time interval storage column 68 correspond to evaluation information (evaluation data), respectively, and evaluation information is included in the image management record selection process. An evaluation value for each piece of evaluation information is determined based on a predetermined evaluation reference value, and an image evaluation value is calculated based on the determined evaluation value. Further, the title to time interval stored in the title storage column 62 to the time interval storage column 68 may be updated at the time of displaying a list image or reproducing an image.

  Further, the image management record 60 is sorted using the designated period and the image evaluation value as a key when the list image is displayed, and a predetermined number of images are extracted in descending order of the image evaluation value.

  FIG. 7 is a diagram showing an embodiment of an evaluation information digitizing table for digitizing evaluation information as a parameter. The evaluation information digitizing table 70 is an evaluation reference value A as shown in the image management record selection process. , B, C, D, E, and F, an evaluation value is determined for each piece of evaluation information, and an image evaluation value is calculated by a predetermined calculation formula. The image evaluation value is, for example, an evaluation formula: α = (A + B + C + E + F) × D where the evaluation value reference value of each evaluation information is A, B, C, D, E, F and the image evaluation value is α in FIG. ;

  In the example of FIG. 7, among the evaluation information, the evaluation reference value of the time stamp is 0, and if a title or a comment is set, 5 is given and set to mean that the user is more interested in that amount. If not, 0 is given. The rating (favorite) is a value set by the user, and any one of 1 to 5 is set (default value = 1). The number of viewing times is set as the number of viewing times = score, but when it exceeds 10, it is fixed to 10. The viewing time is a value calculated as, for example, accumulated time (minutes) / 60 minutes, and the calculated value (rounded down after the decimal point) = score, but if it exceeds 10, it is fixed to 10.

  Further, the time interval is a value obtained by quantifying a value corresponding to the calculated value of the shooting interval based on the time interval quantification table 90 of FIG. 8, and the corresponding value is obtained as a time interval with reference to the quantification table. It will be.

  FIG. 8 is a diagram showing an embodiment of a time interval digitizing table for digitizing time interval information as a parameter. The time interval digitizing table 80 shows the shooting time of the image taken immediately before. The difference is divided as shown in the figure, and a score is given for each division to be a parameter (time interval). The shooting interval for 30 days or more is fixed at 9. By setting the time interval in this way, images with the smaller difference in shooting time interval are often images obtained by continuously shooting the same subject at the same location, so the time interval score is reduced. It is possible not to extract continuously photographed images as representative images. In addition, the reproduction of an image with a large shooting interval takes into account the fact that the user's impression and interest in the image are high and the utility value is high.

  FIG. 9 is a diagram showing an example of the evaluation value for each evaluation information of the image Y when calculating the image evaluation value of the recorded image. The evaluation values A, B, C, D, E, and F of the evaluation information are as follows. In the selection process of the image management record, the evaluation information of the image information record corresponding to each image is obtained by quantifying each image based on the evaluation reference value of the evaluation information digitizing table 70 as shown in FIG. . When the image evaluation value of the image Y is obtained by the above-described evaluation formula: α = (A + B + C + E + F) × D based on this evaluation value, the image evaluation value of the image Y = (0 + 0 + 0 + 3 + 1 + 3) × 1 = 7.

(Image display operation)
FIG. 12 is a flowchart showing an outline of the operation of the electronic album device at the time of image reproduction. This flowchart shows the function of determining the size of the list display screen / image extraction / display function of the electronic album device 1 of the present invention. This is for explaining a program for realizing the above.
The following processing will be basically described by an example in which the control unit 17 executes according to a program stored in advance in a program memory such as a flash memory, but it is not necessary to store all functions in the program memory. Alternatively, a part or all of the information may be received via a network. Hereinafter, the electronic album device 1 is connected to the home television receiver 200, and the home television connected to the user by reproducing an image recorded in the electronic album device 1 by giving an instruction from the remote control device 2. Taking the case of display on a receiving device (digital television) 200 as an example, the case where the television receiving device 200 is a device having a screen with an aspect ratio of 4: 3 is the standard display mode, and the device having a screen with an aspect ratio of 16: 9 is used. The case will be described below as a wide display mode.

In FIG. 12, when the user presses the still image display button 2-1 or the moving image display button 2-2 of the remote control device 2, the electronic album device 1 is turned on and the operation program is started.
When the electronic album device 1 and the television receiver 200 are connected by the cable 250, the display mode acquisition unit 10 sends a display mode information transmission request (control signal) to the television receiver 200 and is sent from the television receiver 200. The aspect ratio of the incoming screen is detected and sent to the control unit 17 (step S0). The control unit 17 examines the detection result sent from the display mode acquisition unit 10, and the television receiver 200 displays the screen with the aspect ratio of 4: 3. In the case of a device having a display mode, the flag value indicating the standard display mode is determined to be stored in the RAM and the process proceeds to step S2. In the case of a device having a screen with an aspect ratio of 1: 9, the wide display mode is selected. The flag value indicating the wide display mode is held in the RAM and the process proceeds to step S3 (step S1).

  In the case of the standard display mode, the control unit 17 stores the format data of the list display screen for the standard display mode (see FIG. 2A) and the displayable number K per line (K = 7 in this embodiment). The image is taken out from the memory 16 and developed on the VRAM 19 via the VRAM controller 20, and then transmitted to the television receiver 200 via the VRAM controller 20 through the digital video encoder 21, digital video signal output unit 24, and cable 250. The image is displayed on the screen, and the process proceeds to step S4 (step S2).

  In the wide display mode, the control unit 17 formats the format data of the list display screen for the wide display mode (see FIG. 2B) and the displayable number K per line (K = 10 in this embodiment). Is taken out from the storage memory 16 and developed on the VRAM 19 via the VRAM controller 20, and then transmitted to the television receiver 200 via the digital video encoder 21, digital video signal output unit 24, and cable 250 via the VRAM controller 20. , Display on the screen, and proceed to step S4 (hereinafter, the operation from the control unit 17 for displaying data on the television receiver to the transmission to the television receiver 200 is simply referred to as “send data and receive television”. Display on the apparatus 200 ”) (step S3).

  At this time, the display attribute code is sent to the television receiver 200 to highlight the front display column 41 of the list display screen (step S4).

  Next, the control unit 17 initializes the row counter (count value = 0) and proceeds to step S6 (step S5).

  When the user displays the list display screen, the user operates the remote control device 2 to specify one of the signs (day, month, year, age) in the period specification field 42, so that the control unit 17 controls the remote control signal receiving unit 25. When “day” display is designated, the process proceeds to step S7. When “month” display is selected, the process proceeds to step S9. When “year” display is selected, the process proceeds to step S11. If “age” display is selected, the process proceeds to step S13. If an end operation is performed, the process ends and the power is turned off. If there is no period designation or end operation, the process waits until a period designation or end operation is performed (step S6).

  When “day” is designated as the designated period, the control unit 17 sends a display attribute code to the television receiver 200 to change the display color of the “day” designation indicator 42-1 and highlight it (step S7). ) All image management records recorded in the storage memory 16 are sorted by date, and the image management records for five days are extracted so that the image data for five days before the current date is the image to be evaluated. Forward to. At this time, the time stamp storage column 72 of the extracted image management record is checked and the latest date is stored as the specified period in the DRAM 15 (or in the RAM of the control unit 17), and the process proceeds to step S15 (step S8).

  When “month” is designated as the designated period, the control unit 17 sends a display attribute code to the television receiver 200 to change the display color of the “month” designation indicator 42-2 and highlight it (step S9). ) All the image management records recorded in the storage memory 16 are sorted by month, and the image management records for 5 months are extracted so that the image data for 5 months before the month including the current date is used as the evaluation target image. Then, the data is transferred to the DRAM 15. At this time, the time stamp storage field 72 of the extracted image management record is checked and the latest month is stored as the designated period in the DRAM 15 (or in the RAM of the control unit 17), and the process proceeds to step S15 (step S10).

  When “year” is designated as the designated period, the control unit 17 sends a display attribute code to the television receiver 200, changes the display color of the “year” designation indicator 42-3, and highlights it (step S11). ) All the image management records recorded in the storage memory 16 are sorted by year, and the image management records for five years are extracted so that the image data for five years before the year including the current date becomes the evaluation target image. Then, the data is transferred to the DRAM 15. At this time, the time stamp storage field 72 of the extracted image management record is checked and the latest year is stored as the designated period in the DRAM 15 (or in the RAM of the control unit 17), and the process proceeds to step S15 (step S12).

  When “age” is designated as the designated period, the control unit 17 sends a display attribute code to the television receiver 200 to change the display color of the “age” designation indicator 42-4 (step S13), and the storage memory 16 All the image management records recorded in the above are sorted by age, and the image management records for 50 years are extracted and transferred to the DRAM 15 so that the image data for the 5's before the age including the current date is used as the evaluation target image. To do. At this time, the time stamp storage column 72 of the extracted image management record is checked and the latest age is stored as the designated period in the DRAM 15 (or in the RAM of the control unit 17), and the process proceeds to step S15 (step S14).

  The control unit 17 classifies the image management records (FIG. 6) extracted in any of the above steps S8, S10, S12, and S14 by calculating image evaluation values based on the evaluation reference values as shown in FIG. Then, K (K is the number that can be displayed) images (representative images) are selected in descending order of the image evaluation value, and the process proceeds to step S16 (step S15).

  The control unit 17 sorts the image management records selected in step S16 in the order of time stamps, and then sequentially extracts image data (representative image data) corresponding to the selected image management records from the storage memory 16, and the reduced image. , And the video data of the number of reduced images (maximum K per line) to be displayed in one line is sequentially sent to the television receiver 200 and displayed as an image for one line (step S16).

  After adding 1 to the row counter, the control unit 17 proceeds to step S18 assuming that the display row is displayed if the value of the row counter exceeds 5, otherwise displays the representative image on the next display row. The process returns to step S15 for display (step S17).

  When the user desires to view all images within the period after the representative image is displayed on the list display screen, the user can operate the remote control device 2 to designate “all items” display in the period designation column 42. The control unit 17 examines the signal from the remote control signal receiving unit 25, and proceeds to step S19 if “all cases” display is designated, otherwise proceeds to step S20 (step S18).

  When “all items” is designated, the control unit 17 extracts and sorts all the image management records in the current period in the order of the time stamp, extracts the corresponding image data, generates the reduced image, and reduces the image. The video data of the image is sequentially sent to the television receiver 200 to display 5 rows × K reduced images (step S19).

  After the image is displayed on the list display screen, the user operates the remote controller 2 to scroll the display line up and down to display other representative images within the specified period, or operates the cursor button 2-4. Since the target line can be changed, the control unit 17 examines the signal from the remote control signal receiving unit 25, and proceeds to step S21 if the up / down scroll button is operated, and proceeds to step S22 otherwise (step S20). ).

  When the up / down scroll key is operated, the control unit 17 is scrolled in the scroll direction to display another representative image (reduced image) within the designated period, and the process returns to step S18 (step S21).

  The control unit 17 examines the signal from the remote control signal receiving unit 25. If there is a line change instruction, the process proceeds to step S23, and if there is no line change instruction, the process proceeds to step S24 (step S22).

  If there is a line change instruction, the period of the line specified by the instruction is specified as the specified period, and the process returns to step S18 (step S23).

  When the user wants to enlarge the reduced image displayed on the list display screen, the user operates the cursor key 2-4 of the remote control device 2 to select and specify a desired image with the cursor, and presses the confirmation key 2-3. Then, the control unit 17 examines the signal from the remote control signal receiving unit 25, and if the cursor is on the reduced display image and the confirmation key 2-3 is pressed, it is assumed that there is an enlarged display instruction and the process proceeds to step S25. If not operated, the process proceeds to step S26 (step S24).

  When there is an enlargement instruction operation, the control unit 17 takes out the image data corresponding to the designated reduced image data from the storage memory 16 and expands and enlarges it, and sends the enlarged image data to the television receiver to display the enlarged image. Display. At this time, the control unit 17 counts the viewing time of the enlarged image and accumulates the viewing time counted in the viewing time stored in the viewing time storage column 77 of the corresponding image management record when the screen display ends. Further, 1 is added to the viewing time count in the viewing time count storage column 76 of the image management record to update it (step S25).

  The control unit 17 examines the signal from the remote control signal receiving unit 25 and terminates the image display process if the end key 2-11 is pressed, and otherwise restores the display color attribute of the list legal screen. The display contents (period, image, and other data) on the list display screen are cleared, and the process returns to step S4 (step S26).

  Through the operation shown in the flowchart of FIG. 12, the electronic album apparatus 1 automatically acquires the aspect ratio of the screen of the connected television receiver, and displays a list display screen having a size corresponding to the acquired aspect ratio. Since it can be displayed on the screen of the receiving device, the display area of the television screen can be used effectively. Further, among the images recorded in the storage memory 16, the evaluation information of the images taken within the designated period is digitized by the weighted evaluation reference values as shown in FIG. An evaluation value (= image evaluation value) of each image based on the reference value is calculated by a predetermined evaluation formula, and a predetermined number of images are extracted as representative images in the order of the evaluation value, and connected television receivers Can be displayed on the list display screen that is displayed on the full screen.

  Since the viewing time and the number of viewing times are automatically updated when the image selected and designated in step S25 of the flowchart of FIG. 12 is enlarged and displayed, the evaluation value of the image changes depending on the viewing time and the number of viewing times. That is, as the image is viewed, the evaluation value of the viewing time and the number of viewing times automatically increases, and the image evaluation value also increases.

  In the flowchart of FIG. 12, the external image display device such as the television receiver 200 is an example of a device that displays digital video. However, the path of the output data from the VRAM 19 is the VRAM controller 20, the analog video signal output unit. 23, by using the cable 250, the present invention can also be applied to an apparatus that displays an analog video.

  In step S0 of the flowchart of FIG. 12, the display mode acquisition unit 10 transmits a display mode information transmission request signal to the television receiver 200, detects the aspect ratio transmitted from the television receiver 200, and controls the control unit. However, when the electronic album apparatus 1 and the television receiver 200 are connected by the cable 250, the display mode acquisition unit 10 displays the screen of various information sent from the television receiver 200. The aspect ratio may be detected and sent to the control unit 17 ”.
