Go to 604.

In step S604, data relating to the image recorded from the memory card to which the cursor has moved is read out and stored in the nonvolatile memory 127 or RAM 125. Then, in step S605, the number of still image and moving image files is calculated based on the stored data. indicate.

Next, in step S606, it is determined whether or not a thumbnail image display request has been made. If so, the process proceeds to step S607 to perform thumbnail image display and processing for single screen display selected thereby. Execute.

Next, in step S608, it is determined whether or not there is a request for viewing a television program. If there is a request, viewing of the program is executed in step S609. That is, the control unit 106 controls the signal processing unit 105 to switch to send the video signal obtained by receiving the broadcast signal to the graphic processing unit 113 and to send the received audio signal to the audio processing unit 114.

In the next step S610, it is determined whether or not a media playback image display request has been made. If so, a media selection screen is displayed in step S611, and further step S61.
2, the nonvolatile memory 12 of the memory card where the cursor is positioned on the media selection screen.
7 or information on the recorded image file stored in the RAM 125 is read out and the number of still image / moving image files is displayed.

Through the processing as described above, the type of image and the number of files stored in the memory card can be quickly displayed.

Further, FIG. 7 is a flowchart for executing a screen display process corresponding to the number of installed memory cards.

In FIG. 7, the process starts in step S701, and it is determined in step S702 whether or not a media playback instruction has been issued. If it is determined that a reproduction instruction has been given, step S7 is performed.
In 03, it is determined whether or not two types of memory cards are attached. If two types of memory cards are attached, the process proceeds to step S704.

In step S704, a media (memory card) selection screen is displayed, and in step S705, the image recorded on the memory card on which the cursor is moved is divided into a still image and a moving image and the number of files is displayed.

Next, in step S706, it is determined whether or not a memory card has been selected. If selected, a file list of the memory card selected in step S707 is displayed as a thumbnail image.

Next, in step S708, it is determined whether or not a request for single image display or a slide show has been made. If so, a single image display or slide show is executed in step S709.

Next, in step S710, it is determined whether or not a thumbnail display request has been made. If so, the process returns to step S704. If there is no request for thumbnail display, it is determined in step S711 whether or not an instruction to end card playback display has been issued. If so, the process ends in step S712.

If it is determined in step S703 that only one type of memory card is installed, a file list of the installed memory card is displayed as a thumbnail in step S713.

Next, in step S714, it is determined whether or not there is a request for single image display or slide show execution. If there is, a single image display or slide show is executed in step S715.

Next, in step S716, it is determined whether or not a thumbnail display request has been made. If so, the process returns to step S713. If there is no request for thumbnail display,
In step S717, it is determined whether or not there is an instruction to end the card reproduction display. If so, the process ends in step S712.

As described above, since the processing is changed according to the number (type) of memory cards installed, when only one memory card is installed, unnecessary screens (media selection screen) are skipped. Therefore, the processing is simplified and the operation can be easily performed.

Next, details of the image display function in the image display apparatus of the present invention will be described. The state shown in FIG. 5 shows a single image display state selected from the thumbnail image display states. From this state, for example, when the yellow key 210 of the remote controller 129 is operated, the control unit 106 makes the OSD. Control of the signal processing unit 119 or the graphic processing unit 113 stops the display of information relating to the displayed image as shown in FIG.
1, a single image and an icon in the icon display area 802 are displayed.

When the yellow key 210 of the remote controller 129 is further operated, the control unit 106
As shown in FIG. 9, only the image is displayed on the screen 901, and when the yellow key is operated again, the display form shown in FIG. 5 is displayed. Become.

For example, when executing a slide show from the state of FIG. 5, the blue key 207 of the remote controller 129 is operated. Thereby, the control unit 106 sequentially reads the image data recorded on the memory card, sends it to the signal processing unit 105, converts it into uncompressed digital image data, and derives it to the graphic processing unit 113.

In the graphic processing unit 113, an information signal related to an image supplied for display from the OSD signal generation unit 119 is superimposed on the image data and output to be displayed on the video display device 121.

At this time, in the state shown in FIG. 8 or FIG. 9 in which the display of the information related to the displayed image is stopped, the control unit 106 displays the information related to the image displayed on the screen stored in the nonvolatile memory 127 or the RAM 125. The read operation is performed to force display for a predetermined time.

In addition, in such a situation where information on the displayed image is not displayed, not only in a slide show, but also when the user manually switches the display image, the information on the image is similarly forcibly displayed for a predetermined time. It is preferable to configure.

At this time, the display timing may be after switching to a new image, before the image is switched, or displayed across the previously displayed image and the new image. In addition, the image may be displayed in such a manner that the image is inserted at the switching of images without being superimposed on the image.

FIG. 10 shows a state in which information about an image is displayed when the display image is switched in a state where the information about the image is not displayed.
A state in which information 1002 regarding the image is displayed is shown.

FIG. 11 is a flowchart for explaining again the processing at the time of switching the display image in the situation where the display of the information related to the image described above is stopped. In FIG. 11, it is started in step S1101, and in step S1102, it is determined whether or not a memory card (media) image display request has been made. If it is determined that there is, a still image list is displayed from the media selection screen in step S1103. Display thumbnails.

In step S1104, an image to be displayed as a single image is selected from the images displayed as thumbnails and displayed together with information (information) related to the image.

Next, in step S1105, it is determined whether or not there is an instruction to stop displaying information. If it is determined that there is an instruction, only an image (or an image and an icon) is displayed in step S1106.

Next, in step S1107, it is determined whether or not there is an instruction to display the next image. If it is determined that there is, the next image is displayed in step S1108, and further step S11.
In 09, the information of the newly displayed image is displayed for a predetermined time. It should be noted that the processing order of steps S1108 and S1109 can be reversed as described above.

Next, in step S1110, it is determined whether or not a thumbnail image display request has been made. If it is determined that there has been a request, the process returns to step S1103. If it is determined that there is not, it is determined whether or not there is an instruction to end the reproduction of the memory card in step S1111. If there is, the process is ended in step S1112 and it is determined that there is not. Returns to step S1107.

If it is determined in step S1105 that there is no instruction to stop displaying information, the process proceeds to step S1113, where it is determined whether or not there is an instruction to display the next image. In step S1114, the designated image is displayed with information.

Next, in step S1115, it is determined whether there is a thumbnail image display request. If it is determined that there is a thumbnail image display request, the process returns to step S1103. If it is determined that there is not, it is determined whether or not there is an instruction to end the memory card reproduction in step S1116, and if there is, the process is ended in step S1112 and it is determined that there is not. Returns to step S1113.

As described above, when the display image is switched automatically or manually in a state where the display of information (information) related to the display image is stopped, the information of the next image to be displayed is forcibly displayed for a predetermined time. By configuring so that the content of the displayed image can be accurately recognized, the target image can be quickly selected from the many images recorded on the memory card. It will be.

Next, processing for changing the display angle of an image will be described. If the red key 208 of the remote controller 129 is operated on the screen shown in FIG. 4, the display angle of the image where the cursor 402 is located is switched. That is, the control unit 106 controls the graphic processing unit 113 or the video processing unit 120 to execute processing for switching the display angle of the selected image among the thumbnail images. Further, at this time, the control unit 106 causes the nonvolatile memory 127 or the RAM 125 to store information that the display angle of the image has been changed.

As a result of executing the process of changing the display angle of the image, as shown in FIG.
The image is displayed in a state rotated counterclockwise by 0 degrees.

In order to switch from the state shown in FIG. 12 to single display of an image whose display angle has been changed, screen 1
The determination key 206 of the remote controller 129 corresponding to the single image display switching icon 1203 in the icon display area 1202 of 201 is operated.

As a result, as shown in FIG. 13, the image whose display angle is switched in FIG. 12 is displayed alone in a state where the display angle is similarly switched.

According to this embodiment, information indicating that the image display angle has been changed is stored in the nonvolatile memory 1.
27 or RAM, for example, even when switching to viewing a television program and switching to viewing a playback image on a memory card again, information on the image whose display angle is switched from the memory. Can be restored to the state shown in FIG. 12 or FIG.

FIG. 14 is a flowchart for explaining the display angle switching process described above again. In FIG. 14, it is started in step S1401, and it is determined in step S1402 whether or not a memory card image display request has been made. If it is determined that there is, a still image list is displayed as a thumbnail image in step S1403. .

In step S1404, thumbnail image display or single image display processing is executed based on the displayed still image list. Next, in step S1405, it is determined whether or not there has been an instruction to change the display angle of the image.
In 406, the changed data is stored in the nonvolatile memory 127 or the RAM 125, and in step S1407, the image is displayed at an angle based on the data. If it is determined in step S1405 that there has been no display angle change instruction, the process returns to step S1404.

Next, in step S1408, it is determined whether an image display request other than that for the memory card has been made. If it is determined that there has been an image display, the image requested in step S1409 is displayed. If it is determined that there is not, the process returns to step S1404.

Next, in step S1410, it is determined whether or not a memory card image display request has been made. If it is determined that there has been a request, the memory card image is displayed at a display angle based on the data stored in the memory in step S1411. . On the other hand, if it is determined that there is not, the process returns to step S1409.

Next, in step S1412, it is determined whether or not there is an instruction to end the memory card reproduction. If it is determined that there is an instruction, the process ends in step S1413. If it is determined that there is not, the process returns to step S1404.

According to the embodiment described above, when the display angle of the image is changed, since the data is stored in the memory, for example, after watching a television broadcast program other than the memory card playback image, for example. Even when the memory card playback image is displayed again, the image whose display angle is changed is displayed with the display angle changed based on the stored data. It is possible to save the trouble of changing.

Next, a process for changing the slide show display time interval will be described. For example, when the blue key 207 of the remote controller 129 is operated on the screen shown in FIG.
The slide show is started under the control of 06, and the screen at that time is shown in FIG.

In FIG. 15, images are sequentially switched and displayed on a screen 1501 and, at the same time, information (information) regarding the display image is also displayed. Furthermore, the icon display area 150
2, an icon corresponding to the color key of the remote controller 129 is displayed, a pause icon 1503 for temporarily stopping the slide show image switching process corresponding to the red key, and a slide show display time interval corresponding to the green key are set. A display interval setting icon 1504 is displayed.

When the green key 209 of the remote controller 12 is operated in the state shown in FIG. 15, a window 1602 for setting a slide show time interval is displayed on the screen 1601 as shown in FIG. The window 1602 displays six set times, and the cursor 160 indicated by diagonal lines with the cursor key 205 of the remote controller 129.
The display interval of the slide show can be changed by moving 3 to the display frame of the time to be set and operating the enter key 206. In addition, E of the remote controller 129
By operating the XIT key 204, the display of the window 1602 for setting the time interval can be stopped.

The process for setting the slide show time interval described above will be described again with reference to the flowchart of FIG. In FIG. 17, the process starts in step S1701 and is started in step S1702.
In step S1703, image data is read from the memory card and continuously determined at time intervals based on the data stored in the memory. The display is sequentially switched.

Next, in step S1704, it is determined whether or not there has been a request to change the display time interval. If it is determined that there has been a request, a time interval setting screen is displayed in step S1705, and the time interval is changed in step S1706 to the memory. Updating the stored data, step S
Returning to 1703, the slide show is executed at a new time interval.

If it is determined in step S1704 that there is no request for changing the display time interval, it is determined in step S1707 whether or not an instruction to end the slide show has been issued. If so, the process ends in step S1708. If there is no end instruction, the process returns to step S1703.

In the embodiment described above, it is possible to call a screen for changing the time interval while the slide show is being executed, and to change the time interval based on the screen. Since the slide show can be resumed immediately, the operation is simplified.

Next, enlargement display processing will be described. For example, in the screen shown in FIG. 8, the image is enlarged and displayed by operating the green key 209 of the remote controller 129. In this embodiment, the entire image is first completely displayed. Set to mode.

That is, for example, as shown in FIG. 18, the display state is slightly reduced with respect to the display state of FIG. Further, in the display state of FIG.
When the green key 209 of No. 9 is operated, an image magnified twice is displayed as shown in FIG.

In FIG. 19, a display 1902 indicating that the display is doubled is displayed on the upper right of the display screen 1901, and a triangular mark 1903 is displayed on the upper, lower, left and right edges of the screen.
3 indicates that further images continue. The entire image shown in FIG. 18 may be configured to be automatically switched to the double display image shown in FIG. 19 after being displayed for a predetermined time.

When the green key 209 of the remote controller 129 is further operated from the state shown in FIG. 19, for example, an image magnified by four times is displayed as shown in FIG. FIG.
In the screen 2001, a display 2002 indicating that the display is quadruple is displayed on the upper right, and a triangle mark 2003 is displayed on the top, bottom, left, and right of the screen as in FIG.

In the process of enlarging the display screen, two types of control are possible: enlargement control of the screen and display control of information (information) related to the display image. Therefore, the remote controller 129 in the icon display area 1904 in FIG. As for the icons corresponding to the color keys, a green enlarged icon 1905 and a yellow information display switching icon 1906 are displayed, and no symbol is displayed in the blue and red oval frame. In this screen, the blue key 207 and the red key 208 of the remote controller 129 indicate that they have no function.

Now, the image enlargement process described above will be described again based on the flowchart of FIG. In FIG. 21, it starts in step S2101, and in step S2102,
A single display of a still image is performed.

Next, in step S2103, it is determined whether or not an enlargement display request has been made. If it is determined that there has been a request, an entire still image is displayed in step S2104, and then step S2
At 105, a double image is displayed.

Next, in step S2106, it is determined whether or not an enlargement display request has been made. If it is determined that there has been a request, a 4 × image is displayed in step S2107.

Next, in step S2108, it is determined again whether an enlargement display request has been made. If it is determined that there has been a request, the process returns to step S2107 to continue displaying the 4 × image. In other words, in this embodiment, the 4 × display is maximized.

If it is determined in step S2108 that there has been no enlargement display request, step S21 is executed.
In step 09, it is determined whether or not an enlargement display end instruction has been issued. If it is determined that there has been an instruction, in step S2110 the display is switched to the standard image display, and the process ends in step S2111.

If it is determined in step S2106 that there has been no enlargement display request, it is determined in step S2112 whether an enlargement display end instruction has been issued, and if so, the process proceeds to step S2110 to switch to standard image display. When it is determined that there has been no enlargement display end instruction, the process returns to step S2105 to continue displaying the double-size image.

In the flow described above, step S2104 and step S2105 are automatically processed in conjunction with the determination process of step S2103.
If the process is temporarily interrupted in step 4 and further enlargement display is requested, step S2105 may be executed.

In the above-described image enlargement display processing, a step for displaying the entire image once is provided, so that the user can surely recognize how the original image is enlarged. Therefore, the operability is improved.

Further, a process for moving the display image will be described. For example, in the double image display state shown in FIG. 19, the display position of the image can be changed by operating the cursor key 205 of the remote controller 129.

Whether or not it can be moved is indicated by the triangular marks 1903 displayed on the top, bottom, left and right of the screen. If this is displayed, it can be moved in that direction, but if the display disappears, It has been moved to the end of.

The processing will be described again with reference to the flowchart shown in FIG. In FIG. 22, it is started in step S22, and in step S2202, it is determined whether or not an enlargement display request has been made.

Next, in step S2204, it is determined whether or not there has been a request to change the display position. If it is determined that there has been a request, the display position is changed and displayed together with four marks in step S205.

Next, in step S2206, it is determined whether or not the display has reached the end. If it is determined that the display has not reached, the process returns to step S2204.

If it is determined that the display has reached the end, display of the mark in the direction reaching the end is stopped in step S2207, and then it is determined in step S2208 whether a display position return request has been made. If it is determined, the process returns to step S203. If it is determined that there has been no enlargement display end instruction is determined in step S2209, and if it is determined that there has been, the process ends in step S2210, and if it has been determined that there has not been any. Return to step S2207.

If it is determined in step S2204 that there has been no display position change request, the process proceeds to step S2211, where it is determined whether an enlargement display end instruction has been issued. If YES, the process returns to step S2204.

According to the above-described embodiment, when the image is moved, if it reaches the end, the display of the mark in that direction is stopped and not displayed, so that the user can accurately determine the moving state of the image. This also contributes to the improvement of operability because it does not require extra operations.

In the above description, the case where a still image is displayed has been described. Next, a moving image display example will be described. The display of moving images is basically the same as the display of still images, but there are some differences in details, which will be mainly described.

As shown in FIG. 4, the remote controller 129 is displayed in the thumbnail image display state.
When the yellow key 210 is operated, the control unit 106 reads the thumbnail information of the moving image file from the memory card, sends it to the signal processing unit 105, performs processing, and performs processing on the graphic processing unit 1.
13 to output. Further, the information of the moving image is stored in the nonvolatile memory 127 or the RAM 12.
6 is supplied to the OSD signal generation unit 119 and data relating to the icon is R
The data is read from the OM 125 and supplied to the OSD signal generation unit 119 to generate an OSD signal, which is derived to the graphic processing unit 113.

The graphic processor 113 mixes these signals and sends them to the video display 121 via the video processor 120 for display. As a result, thumbnail display of moving images is realized as shown in FIG.

In FIG. 23, a symbol (actually a logo mark) 2302 indicating the type of the memory card is displayed on the upper right of the screen 2301, and 12 images are displayed as thumbnails at the center of the screen, as in the case of a still image. It is displayed.

Further, a cursor 230 indicated by a hatched frame below the area where the image is displayed.
Information on the image surrounded by 3 is displayed. This information is basically the same as in the case of a still image, and the shooting date and time, the name of the file, the information indicating the number of the entire image where the cursor 2303 is located, and the resolution are displayed. ing.

In addition, audio information may be added to the moving image, and whether or not audio is added is indicated by a musical note symbol 2304. In the example of FIG. 23, the moving image file to which the audio information is added is displayed. It turns out that. When music information is not added, for example, a musical note mark 2
This can be expressed by processing such as drawing a diagonal line 304.

Further, in FIG. 23, in the icon display area 2305, an icon 2306 for switching to single display and starting playback of a moving image, and a display time for setting a moving image as a screen saver image are set. A screen saver setting icon 2307, a still image thumbnail display switching icon 2308 for switching to still image thumbnail display, and an EXIT icon 2309 for returning the display screen are displayed.

In FIG. 23, when the enter key 206 of the remote controller 129 is operated, the control unit 106 reads the actual moving image data of the thumbnail image where the cursor 2303 is located from the memory card and supplies it to the signal processing unit 105 for processing. Graphic processor 113
Then, the image is displayed on the image display device 121 via the image processing unit 120.

FIG. 24 shows an example in which a moving image is displayed. A moving image is displayed at the center of the screen 2401. In addition, a display unit 2402 that indicates an elapsed playback time in analog form is provided at the top of the screen, information about the displayed image is displayed at the bottom of the moving image, and an icon display area 2403 at the bottom. Is formed.

In the icon display area 2403, the icons 2404 and 2405 for switching the moving image to be displayed to the previous one or the next one in the thumbnail image, and for pause (pause) the reproduction of the moving image. A blue fast reverse icon 2407, a red fast forward icon 2408, a green enlarged icon 2409, and a yellow information display control icon 2410 corresponding to the color key of the remote controller 129 are provided, and a thumbnail display is further provided. There is provided an EXIT icon 2411 for returning to the state. By operating these icons, various functions can be executed.

As described above, according to the image display device of the present invention, the time interval can be changed while executing the function of continuously switching and displaying a plurality of images at a predetermined time interval. Therefore, an efficient operation can be executed without interrupting the continuous switching display.

Furthermore, when changing the display angle of the image, the change data is stored in the memory and the display angle is changed based on the change data. Therefore, if one of the thumbnail images and the single display image is changed, the display angle is changed. The other display angle can be changed, and even if the playback image display operation of the memory card is stopped and then restarted, the memory data is saved, so the image display angle can be easily changed. And high operability can be realized.

In addition, when the image is enlarged and displayed, a mode in which the entire image is completely displayed is put in the middle, so that the user recognizes the entire content of the image and displays the enlarged image, which is useless. The operation can be omitted.

In addition, when the image is displayed in a state that does not fit on the screen, the presence of the hidden part image is displayed with a mark, so that the user can easily move the image. .
