To do.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing an appearance of a digital camera 1 which is an embodiment of an image display device of the present invention. The digital camera 1 in FIG. 1 has a shooting mode and a playback mode, and this digital camera 1 when switched to the playback mode constitutes an example of the image display device according to the present invention.

  FIG. 1A shows a view of the digital camera 1 viewed from the front, and FIG. 1B shows a view of the digital camera 1 viewed from the back.

  As shown in FIG. 1A, a photographing lens 1101 is provided at the center of the body 1a, and a light emission window 190A is provided obliquely to the upper right of the photographing lens 1101. Furthermore, a release button 10a and the like are provided on the upper surface of the body 1a. Further, as shown in FIG. 1B, a display screen 125A is provided on the back of the body 1a, and next to the display screen 125A is a MENU / operated when a menu is displayed on the display screen 125A. The cross key 10c operated when selecting the OK button 10b or any item in the menu, the DISP / BACK button 10d operated when the display screen 125A is hidden or displayed, and the display screen 125A On the top, controls such as a playback button 10e and a zoom switch 10f which are operated when a captured image is reproduced and displayed are provided. Hereinafter, these operators may be collectively referred to as an operator group 10. In the present embodiment, an example of the display screen according to the present invention is configured by the display screen 125A.

  FIG. 2 is a block diagram showing an internal configuration of the digital camera 1 of FIG.

  As shown in FIG. 2, the operation of the digital camera 1 of the present embodiment is comprehensively controlled by the CPU 100, and a main memory 100B is connected to the CPU 100 via an address bus 104A and a data bus 104D. . A program is written in the main memory 100B. In the digital camera 1 of the present embodiment, the CPU 100 accesses the main memory 100B via the memory control unit 100A in response to the power being turned on, and controls the operation of the digital camera 1 according to the procedure of the internal program. To start.

  Here, the operation in the shooting mode will be described first.

  Image data representing a subject captured by the left photographic lens 1101 in FIG. 2 is recorded on the recording medium 128 on the right side, so the components will be described in order from the left side in FIG.

  A subject captured by the photographic lens 1101 in the photographic optical system on the left side of FIG. At this time, it is necessary to focus the subject light whose focus and exposure are adjusted on the CCD 1104. Therefore, the CPU 100 controls the aperture driving unit 102 based on the integration result of the integration unit 129 described later, and the aperture 1102 in the photographing optical system. Is adjusted by adjusting the focus position of the focus lens in the photographic lens 1101 by controlling the lens driving unit 101 by the CPU 100.

  In this embodiment, a filter 1103 such as an optical low-pass filter or an infrared cut filter is inserted into a photographing optical system including the photographing lens 1101 to suppress the occurrence of aliasing, or the CCD 1104 (in this example, a CCD solid state). Since the sensitivity on the infrared side of the imaging device is high, the adverse effect of infrared rays is prevented.

  In this way, the subject in the direction in which the photographing lens 1101 is directed is imaged on the CCD 1104, image data representing the subject is generated by the CCD 1104, and image data representing the subject is output from the CCD 1104 to the analog signal processing unit 121.

  In the digital camera as shown in FIG. 1, the display screen 125A on the back side is used instead of the viewfinder, so the CPU 100 instructs the image sensor driving unit 103 when the power is turned on to display a moving image on the display screen 125A. Then, the CCD 1104 generates an image at predetermined intervals, and the analog signal processing unit 121 outputs the image data. In response to the image data output from the CCD 1104, the analog signal processing unit 121 performs noise reduction processing and the like, and the image data subjected to the noise reduction processing is converted into digital signal image data by the A / D 122 in the subsequent stage. Image data is directed onto the data bus 104D.

  All of the image data guided onto the data bus 104D is first transferred to the frame memory in the digital signal processing unit 123. The digital signal processing unit 123 performs processing such as conversion from RGB signals to YC signals, and the image data converted into YC signals is displayed in a display buffer memory (not shown) in the display control unit 124 under the control of the CPU 100. Forwarded to Then, an image based on the image data is displayed on a display screen 125 </ b> A included in the display unit 125 under the control of the display control unit 124. As described above, since the CPU 100 instructs the image sensor driving unit 103 to cause the CCD 1104 to generate and output images at predetermined intervals, the contents of the image buffer memory in the display control unit 124 are set at predetermined intervals. By rewriting each time, the images on the display screen are switched one after another, and a subject image (hereinafter referred to as a through image) captured by the photographing lens 1101 is displayed on the display screen 125A provided in the display unit 125.

  Here, when the release button 10a is pressed at a photo opportunity while viewing the through image on the display screen 125A, the CPU 100 first causes the integrating unit 129 to perform photometry and distance measurement when the release button 10a is half-pressed. The photometry result and the distance measurement result are received and an instruction is given to the aperture driving unit 102 to adjust the diameter of the aperture, and an instruction is given to the lens driving unit 101 to move the focus lens to the in-focus position to perform the focus adjustment.

  Subsequently, when fully pressed, the CPU 100 instructs the image sensor driving unit 103 to perform exposure by causing the CCD 1104 to perform exposure at a shutter speed calculated in advance when the shutter button is half-pressed based on the result of integration by the integration unit 129. After completion, the image data representing the subject is output to the analog signal processing unit 121. At this time, when the CPU 100 determines that the field luminance is dark, the light emitting means (not shown) emits light, and the photographing auxiliary light is emitted from the light emitting window 190A toward the subject to perform photographing.

  When the image data output from the CCD 1104 is supplied to the analog signal processing unit 121, the analog signal processing unit 121 performs noise reduction processing and the like, and the image data converted into a digital signal by the A / D 122 is the data bus 104D. All of the image data led to the data bus side is led into the frame memory in the digital signal processing unit 123.

  The digital signal processing unit 123 performs signal processing such as YC conversion processing, and after the signal processing is performed by the digital signal processing unit 123, this time, compression is performed based on the address designation of the address bus 104A via the data bus 104D. Image data is transferred to the decompression processing unit 126, and the compression / decompression processing unit 126 compresses the image data. Further, the compressed image data is similarly transferred to the external memory control unit 127 and recorded on the recording medium 128 under the control of the external memory control unit 127.

  Next, the flow of image data during reproduction will be described.

  The digital camera 1 of the present embodiment includes an image processing unit 130 that is also used as a display buffer during reproduction. The image processing unit 130 receives an instruction from the CPU 100 when the playback button 10 e is operated, reads an image from the recording medium 128, processes the read image if necessary, and outputs the processed image to the display control unit 124. . The display control unit 124 receives the image data from the image processing unit 130 and displays an image on the display screen of the display unit.

  The above is the main operation of the digital camera 1 of the present embodiment.

  Here, the digital camera 1 of the present embodiment is provided with the above-described slide playback function. When the playback button is pressed and the menu button 10b is pressed, a menu screen is displayed. When “slide show” is selected in the “playback” item, all images in the recording medium 128 are slid and played in order of shooting time.

  FIG. 3 is a diagram for explaining the state of the display screen 125A when slide reproduction is performed. FIG. 3A shows a state in which slide playback is performed, and FIG. 3B shows a future display in the second display area at the periphery excluding the first display area 1250. An example is shown in which one or more thumbnail images selected from thumbnail images corresponding to images to be scheduled are arranged side by side. Note that the size of the first display area 1250 is configured with the same aspect ratio as the aspect ratio of the display screen 125A in order to ensure the visibility of the image being slid and reproduced in the first display area.

  As shown in FIG. 3A, in the first display area 1250 of the display screen 125A, the CPU 100 and the external memory control unit 127 cooperate with each other to obtain a plurality of images in the order of shooting times acquired from the recording medium 128. Slide playback is performed. At this time, the image in the first area 1250 is displayed so as to cover the thumbnail images arranged in the second area 1251 on the periphery, and only a part of the thumbnail images in the second area 1251 is displayed. "Hidden state" is visible.

  When the left key 102c or the right key 101c is operated in the state of FIG. 3A, the display of the plurality of thumbnail images 1251A in the second area 1251 becomes active and the display screen 125A is displayed. The display changes as shown in FIG. More specifically, the image in the first display area 1250 is reduced so that the entire thumbnail image in the second display area 1251 is displayed.

  At this time, the CPU 100 instructs the display control unit 124 to indicate that the thumbnail image is selected as the thumbnail image displayed at a specific position in the second area 1251 (see FIG. 3B). The upper left corner is also displayed.

  Further, in response to the frame advance operation of the left key 102c or the right key 101c of the cross key by the user, the CPU 100 moves the display position of the plurality of thumbnail images 1251A displayed in order to display the cursor 1252. In response to the designation of the thumbnail image moved to the current position, images corresponding to the thumbnail image moved to the position where the cursor 1252 is displayed are sequentially displayed in the first area 1250 according to the frame advance operation.

  That is, the CPU 100 and the image processing unit 130 cooperate with each other to control the display control unit 124 in response to fast forward and fast reverse being performed by the frame advance operation of the left key 102c or the right key 101c of the cross key 10c. The thumbnail images are sequentially moved to the position where the cursor is displayed by moving the display positions of the plurality of thumbnail images on the display screen 125A in order, and the cursor 1252 is displayed in the first display area 1250. A process of displaying an image corresponding to the thumbnail image at the current position is executed.

  In the present embodiment, the CPU 100, the image processing unit 130, and the recording medium 128 constitute an example of the acquisition unit referred to in the present invention, and the CPU 100, the image processing unit 130, and the display control unit 124 include the display control unit referred to in the present invention. The CPU 100, the display control unit 124, and the left key 102c or the right key 101c of the cross key constitute an example of the designation means referred to in the present invention.

  A process executed by the CPU 100 and the image processing unit 130 in cooperation with each other so far and controlling the display control unit 124 will be described with reference to the flowchart of FIG.

  FIG. 4 is a flowchart showing a processing procedure of slide reproduction processing executed in cooperation by the CPU 100, the image processing unit 130, and the display control unit 124.

  First, in step S401, the CPU 100 receives an operation of the playback button 10e, instructs the external memory control unit 127 to acquire an image from the recording medium 128, and then instructs the image processing unit 130 and the display control unit 124. Start slide playback. If the CPU 100 determines in step S402 that the predetermined time has elapsed with reference to the internal timer count value, the process proceeds to step S402, and the image processing unit 130 and the display control unit 124 are instructed to switch to the next image. In step S403, the CPU 100, the image processing unit 130, and the display control unit 124 cooperate with each other to repeat the processing in step S402 and step S403 to perform slide reproduction. Here, steps S402 and S403 executed through step S401 correspond to the first display step according to the present invention. Step S401 corresponds to an acquisition step according to the present invention.

  While the CPU 100 still refers to the timer count value in step S402 and a predetermined time has not elapsed, either the left key 102c or the right key 101c or the cancel key 10g is operated in steps S404 and S405. It is determined whether or not an event has occurred.

  If the cancel key 10g is operated here, it is determined in step S405 that an event of “end” has occurred, and the processing of this flow is ended.

  If either the left key 102c or the right key 101c is operated, it is determined in step S404 that a 'fast reverse' or 'fast forward' event has occurred, and the process proceeds to Yes, and a thumbnail image is displayed in step S406. The list display is changed from the non-display state of FIG. 3A to the active state shown in FIG. 3B, and in step S407, the frame cursor surrounding the thumbnail image is moved to a specific position (upper left corner of FIG. 3B). ).

  Thereafter, the processing from step S408 to step S413 is repeatedly executed, and the operation waits for the left key 102c, the right key 101c, or the cancel key 10g to be operated before a predetermined time has elapsed.

  If it is determined in step S410 that the left key 102c or the right key 101c has been operated and a “fast reverse” or “fast forward” event has occurred before the predetermined time has elapsed, the process proceeds to Yes, and in step S411. The thumbnail image at the position where the cursor is displayed is changed by sequentially moving the display positions of the plurality of thumbnail images displayed, and the thumbnail image at the position where the cursor 1252 is displayed in the next step S412. The image to be displayed is displayed in the first display area 1250. Here, assuming that the cancel key 10g has not been operated yet, the process returns to step S408, and the processing from step S408 to step S413 is repeated.

  If the cancel key 10g is operated at this time, it is determined in step S413 that an event of “end” has occurred, and the processing of this flow is ended.

  Further, if it is determined in step S408 that no operation is performed even after a predetermined time has passed, the process proceeds to step S409, and the cursor 1252 is moved in accordance with both the processing status of step S407 and the processing status of step S411. Slide playback is resumed with the image corresponding to the thumbnail image at the displayed position as the first image. That is, when the skip process is executed in step S411, the slide show is restarted from the skipped image. Then, returning to step S402, a series of processing from step S402 to step S405 is repeatedly executed, and when it is determined in step S405 that the cancel key 10g has been operated and an event of "end" has occurred, the processing of this flow is ended. Here, steps S401 and S402 after step S409 correspond to the second display step according to the present invention, and the processing from step S410 to step S412 corresponds to the designation receiving step according to the present invention.

  If the CPU 100, the image processing unit 130, and the display control unit 124 execute the processing of this flow in cooperation, fast forward and fast reverse can be performed during slide reproduction. As a result, the user can easily skip to the desired image at any time by operating the left key 102c or the right key 101c to perform fast reverse or fast forward.

  As described above, an image display apparatus, an image display method, and a program for operating the image display apparatus as an image display apparatus that can freely skip to an image that the user wants to see during slide reproduction are realized.
