  FIG. 3 is a diagram showing the flow of data from the image sensor to the display monitor screen. An image pickup device such as a CCD or CMOS of the electronic image pickup unit 33 obtains a color by providing a filter in front of many photodiodes. There are two types of filters: “primary color filter” and “complementary color filter”. Primary color filters are R (Red), G (Green), B (Blue), complementary color filters are C (Cyan), M (Magenta), Y (Yellow). The number of pixels generally called 3 million pixels, 5 million pixels,... Is the number of photodiodes.

  The charge charged by the photodiode is A / D converted by the video signal processing unit 34, temporarily held in the form of Bayer data corresponding to the pixels of the image sensor, and the luminance and chrominance multiplexed signals (Y, Cb, Cr) by signal processing. Data, also referred to as Y, U, V). The Y, U, V data (hereinafter referred to as image data) is stored in the image memory 35.

  As the number of pixels of the image, 2560 × 1920, 2048 × 1536, 1600 × 1200, 1024 × 786, 800 × 600, 640 × 480 and the like are generally known. In the present embodiment, the image data stored in the image memory 35 is, for example, still image data having luminance (Y) data of 1600 × 1200 pixels and color difference (U, V) data of 800 × 600, respectively. Consists of pixels. This is because the amount of information of the color difference signal is reduced because the luminance signal is more easily perceived by the human eye. In order to display the image data configured as described above on the liquid crystal monitor 17, RGB data matching the number of display pixels of the liquid crystal monitor 17 is created by calculation and written into the VRAM 48. Therefore, there is no direct correspondence between the number of pixels of the image sensor and the number of display pixels on the liquid crystal monitor screen.

  In addition, moving image data is usually configured with a lower image quality (lower pixel density) and 640 × 490 pixels than still image data. If the image memory 35 has a sufficient memory capacity, the moving image data is almost as high as a still image. It may be video data with image quality.

  The liquid crystal monitor 17 has RGB color filters for each display pixel, and a delta arrangement as shown in FIG. 4A and a stripe arrangement shown in FIG. 4B are common.

  The liquid crystal monitor 17 is composed of a monitor screen with a wide aspect ratio of 16: 9. If the number of pixels is 640 × 360 pixels, 640 × 3 (R, G, B) pixels are horizontally arranged in the stripe arrangement. It is arranged, and 360 pixels are arranged in the vertical direction. In the case of the delta arrangement, 640 pixels are arranged in the horizontal direction and 360 pixels are arranged in the vertical direction. In the delta arrangement, the number of display pixels is 1/3, but the color reproducibility is high.

The liquid crystal monitor 17 is a monitor screen having a wide aspect ratio of 16: 9. However, since the image data created by shooting is a 4: 3 aspect ratio of 1600 × 1200 pixels, the image memory 35 can display a 4: 3 image. It is configured to memorize.
The memory configuration of the image memory 35 in FIG. 3 is a delta arrangement, but in the case of a stripe arrangement, each of R, G, and B has an image memory of 100 × 1200 pixels as shown in FIG. If the liquid crystal monitor screen is 1600 × 3 × 1200 pixels, it may be supplied as it is. If the liquid crystal monitor 17 is 640 × 360 pixels as in the present embodiment, thinning is appropriately performed as shown in FIG. Supply. In the case of a delta arrangement, image data is stored in the form of Y, U, and V data, and RGB data is created by calculation at the time of display and sent directly to the display control unit 49.

  A 640 × 360 pixel VRAM (display buffer) 48 is provided in the display controller 34, and display data is created in the VRAM 48. That is, the liquid crystal monitor 17 displays the data in the VRAM 48 as it is. Therefore, even if the image data is only 4: 3, the VRAM 48 has the number of pixels corresponding to the liquid crystal monitor 17, and black, for example, is written in the non-display area.

  The CPU 41 performs JPEG (Joint Photographic Coding Experts Group) compression. JPEG compression is performed on each of the image data Y, U, and V in the image memory 35, and the compressed JPEG-Y, JPEG-U, and JPEG-V are temporarily stored in the data memory 43, and then transferred to the CF or HDD 20 for storage and recording. .

  The reduced image of 480 × 360 pixels and the thumbnail of 160 × 120 pixels are both JPEG-compressed and temporarily stored in the data memory 43, then transferred and stored in the storage medium (CF or HDD) 20, and the main image and Saved in association.

  The CPU 41 reads out the image data stored in the image memory 35 when the still image is stored and recorded, performs still image compression processing, stores and records it in the storage medium 20, and stores and records it in the storage medium 20 during reproduction. The decompressed image data is subjected to decompression processing to reproduce the image data. In addition, when storing and recording a moving image, a continuous image (a plurality of still images) recorded in the image memory 35 is compressed and stored in the recording medium 20, and is stored and recorded in the recording medium 20 during reproduction. The compressed image data is decompressed to reproduce the moving image data, which is stored and recorded in the image memory 35.

Further programmed recording area) is provided in the case.

  FIG. 7 is a diagram showing the state of still image data recorded on the storage medium (CF or HDD) 20. Reference numeral 100 denotes a folder of JPEG-compressed images, which includes a main image 101, a reduced image 102 obtained by reducing the image, and a thumbnail 103 (FIG. 7A). The thumbnail 103 is a reduced image defined by a common standard in order to maintain compatibility with other digital cameras, and the reduced image 102 is an image obtained by reducing the main image at an arbitrary reduction ratio. Is large, for example, almost the same as the size of the monitor screen. In addition, the thumbnail is often almost the same size as when a plurality of images are displayed on a multi-screen by dividing the screen. The header 104 stores information such as the file name, the number of pixels, the shooting date and time, and shooting conditions.

When displaying a still image, the reduced image 102 is normally displayed on the liquid crystal monitor 17. Since the reduced image 102 is a reduced version of the main image 101, there is no degradation in image quality because basically no interpolation processing is performed. However, since the amount of information is reduced by performing thinning or the like for reduction, the image quality of the main image cannot be expressed.
When there is an enlargement instruction at the time of reproduction, there are a case where the reduced image 102 is enlarged and a case where the main image 101 is reduced, and a case where the main image 101 is reduced will be described as an example.

  For example, as shown in FIG. 7B, it is assumed that the main image 101 is 1600 × 1200 pixels, the display size of the liquid crystal monitor 17 is 480 × 360 pixels, and the size of the reduced image 102 is 480 × 360 pixels. Assume that the size is 160 × 120 pixels. The reduced image 102 may be displayed as it is to be displayed on the liquid crystal monitor 17, and the thumbnails may be displayed as they are in order to perform 3 × 3 9-divided multi-screen display. Note that the configuration of the liquid crystal monitor 17 may not match the number of pixels of the image stored, for example, 330 × 220 pixels. In such a case, processing such as interpolation is appropriately performed to match the number of pixels. The enlargement instruction enlarges / reduces the image being reproduced and displayed when the zoom key 11 is operated in the reproduction mode.

  FIG. 8 is a diagram showing the state of a moving image file recorded on the storage medium (CF or HDD) 20. The moving image file 200 is composed of JPEG-compressed moving image data 201, a header 204, and the like. Consists of still images (in the example shown, still images 1-1 to 1-n, still images 2-1 to 2-m, etc. Further, the header 204 has a file name, the number of pixels, shooting date and time, shooting conditions, etc. In addition to this, moving image shooting information such as the number of shot frames, image quality, frame time interval (or shooting speed), corresponding audio data, and audio files is recorded.

  When displaying a moving image, each still image constituting the compressed moving image data 201 is normally decompressed and stored in the image memory 35 on the liquid crystal monitor 17, and each reproduced still image 1-1 to 1-n is reproduced. Are sequentially taken out from the image memory 35 and continuously displayed. Each still image constituting the moving image data usually has a lower image quality than a still image shot in the still image mode, but may have a higher image quality depending on the mode selection at the time of shooting. When a reduction instruction is given during reproduction, the still images constituting the moving image data 201 are reduced and displayed.

  FIG. 9 is a diagram showing some examples of display areas set on the liquid crystal monitor 17 of the digital camera 1 having a wide LCD. In FIG. 9A, a display area R1 having an aspect ratio of 12: 9 is set on the left side of the wide LCD screen having an aspect ratio of 16: 9, and a display area R2 having a predetermined aspect ratio smaller than R1 is set on the right side thereof. 9B is an example in which display areas R2, R3, and R4 having a predetermined aspect ratio smaller than R1 are provided on the right side of the display area R1 having an aspect ratio of 12: 9. FIG. 9C shows an example in which the main image display area R1 having an aspect ratio of 12: 9 is set at the center of the screen, and display areas R2 and R3 having a predetermined aspect ratio smaller than R1 are set on both sides thereof. An area corresponding to the display area set in the liquid crystal monitor 17 is also set in the storage area of the VRAM 48. Further, the number of still image display areas is not limited to the above-described areas of 2 (R2, R3) to 3 (R1, R2, R3). The still image to be displayed may be reduced or enlarged in accordance with the size of the display area and displayed as a whole. However, when the size of the display area is smaller than the entire image, it may be partially displayed without being reduced. Good.

FIG. 10 is a diagram illustrating a conventional moving image display and a display example of a still image cut out from the moving image, and FIG. 11 is a display example of a moving image and a cut out still image on a wide LCD screen according to the moving image editing method of the present invention. FIG.
10, (a) is a display example of a moving image displayed on the liquid crystal monitor screen, and (b) is an example in which the moving image displayed in (a) is cut out at an arbitrary timing and displayed as a still image on the same screen. The moving image 10-1 is covered with the still image 1-2, and the moving image becomes invisible. Note that even if the clipped video is displayed on a part of the screen, a part of the video is covered with a still image and cannot be seen. Therefore, according to the conventional method, a part of the video is covered with the cut still image. Will disappear.

  FIG. 11 shows the reproduced moving image 11-1 in the display area R1 having an aspect ratio of 12: 9 among all display areas of the wide LCD screen 17 having an aspect ratio of 16: 9, and the cut out still image is displayed on the right side (display area). R2, R3) is an example of reduced display, and when the moving image 11M is being played back and displayed, if the user presses the DISP button 15 at an arbitrary timing, it was displayed in the display area R1 when the button 15 was pressed The image 11- (j) is cut out, reduced to the display area R2, and displayed as a still image. In the illustrated example, as described below, as a result of the previous scroll button 11F being clicked once, the image 11- (j-1) one frame before the cut still image 11- (j) is reduced and the display area is reduced. This is an example in which the still image 11- (j) displayed on the display area R2 and displayed on the display area R2 is shifted and displayed on the display area R3. Note that R1, R2, and R3 are display areas that are set in advance. In the standard setting of this embodiment, R1> R2 = R3. However, the present invention is not limited to this, and the user sets an arbitrary size as described later. You can also

  In FIG. 11, reference numeral 11 </ b> F denotes a front scroll button, which can cut out an image in a moving image and display a still image by going back to the frame image taken before the still image displayed by the scroll operation. When the previous scroll button 11F is clicked m times, the image 11- (jm) before m frames of the cut still image 11- (j) is reduced and displayed as a still image in the display area R2, and the display area R2 The still image 11- (j- (m-1)) displayed on is shifted and displayed on the display region R3. When the display areas R4, R5,... Are set, the still image 11- (j- (m-2)), the still image 11- (j- (m-3)),. It is shifted and displayed in the display areas R4, R5,. The pre-scrolling operation can be performed by pressing the SET key 14 after the user operates the cursor key 13 to position the cursor on the front scroll button 11F, and the SET key 14 may be pressed m times to click m times. Become.

  When issuing a cut instruction by operating the DISP button 15 while displaying a moving image, it takes a little time until the user presses the DISP button 15 after trying to cut, so the instruction is delayed, and the desired still image and the cut image are displayed. Although there is a possibility that a difference may occur, a still image can be cut out and displayed from a moving picture by going back to the previous image one frame at a time by the above-mentioned scroll operation, so that a desired still image is clipped by repeating this scroll operation. be able to.

  Reference numeral 11B denotes a rear scroll button, which can cut out a frame image taken after the still image displayed by the scroll operation and display the still image. When the rear scroll button 11F is clicked n times, the image 11- (j + n) after the n frames of the cut still image 11- (j) is reduced and displayed as a still image in the display area R3, and is displayed in the display area R2. A still image 11- (j- (n-1)) is displayed. When the display areas R4, R5,... Are set, the still image 11- (j- (n + 1)), the still image 11- (j- (n + 2),. It is displayed in the areas R4, R5, etc. The rear scroll operation can be performed by pressing the SET key 14 after the user operates the cursor key 13 to position the cursor on the rear scroll button 11B, and clicks n times. The user can press the SET key 14 n times.

  There is a case where it is desired to view an image (for example, the moment of impact in golf and the subsequent form) taken slightly after the image that was cut by operating the DISP button 15 while displaying a moving image to give a cutting instruction. In such a case, the moving image may be returned and a cutting instruction may be given, but it is not always possible to cut a desired still image at a time. However, since the subsequent scroll operation can cut out and display the still image one frame at a time, the desired still image can be reliably cut out by repeating the scroll operation thereafter.

  In the description of FIG. 11, the scroll operation is shown by an example in which the front scroll button 11 </ b> F or the rear scroll button 11 </ b> B is designated with the cursor key 13 and the SET key 14 is pressed to scroll forward or backward. When the button is operated upward or downward, it may be configured to scroll forward or backward.

  Reference numeral 11C denotes a replacement button, and the moving image in the display area R1 is displayed in the designated display area among R1, R2, R3,..., And the still image displayed in the designated display area Can be displayed in the display area R1 (enlarged in the illustrated example). Specifically, the display area of the moving image and the still image can be switched by pressing the SET key 14 after the user operates the cursor key 13 to position the cursor on the switching button 1C.

  In the example of FIG. 11, the still images displayed in the display areas R2, R3,... However, since only a part can be seen even if enlarged on the display areas R2, R3,..., The still image is displayed in the display area R1 having an aspect ratio of 12: 9. The displayed still image may be enlarged, but the reduced image is enlarged, so that the image quality deteriorates. Therefore, the same still image is cut out again from the moving image data based on the position information (or the number of frames from the top) indicating where the still image held at the time of display is in the moving image data, and displayed as it is in the display area R1. To do. In this way, the displayed still image is displayed in the same size as the moving image, and the image quality is not deteriorated. Since the moving image displayed in the display area R1 is displayed in the display area where the still image displayed in the display area R1 is displayed, another still image can be cut out from the moving image by a cut instruction operation.

  Further, when the cursor is moved onto the still image displayed in the display areas R2, R3,... (Or the display area R1 by replacement) and the SET key 14 is pressed, still image data (moving image) corresponding to the still image is displayed. Still image in the data) is recorded in the storage medium 20.

  FIG. 12 is a timing chart for displaying a moving image and a still image on the wide LCD screen in the present embodiment. The moving image start timing, the still image A cutout instruction (depressing the DISP button 15) timing, the still image B cutout instruction timing, The cut-out timing of the still image C is recorded in time series, and the horizontal axis indicates the moving image display period (black banded portion) in the display region R1, the moving image (the still image constituting the moving image data), and the cut-out in the display region R2, respectively. Display period of the selected still images A, B, C, transition of the still images (A, B, C) displayed in the display area R2, display period of the cut out still images A, B,. The transition of the still images (A, B,...) Displayed in the display area R3 is shown.

  In this embodiment, as shown in FIG. 12, the reproduced moving image is continuously displayed in the display area R1 until the reproduction ends or a reproduction end instruction is issued, and the still image A is cut out when the DISP button 15 is pressed. And displayed in the display area R2. Next, when the DISP button 15 is pressed, the still image B is cut out and displayed in the display region R2, and the still image A is displayed in the display region R3. When the DISP button 15 is further pressed, the still image C is cut out and displayed in the display area R2, and the still image B is displayed in the display area R3. The still images A, B, and C are displayed in the display area R2 until the next DISP button 15 is pressed, and sequentially displayed in the display area R3 when the DISP button 15 is pressed.

  As shown in the timing chart of FIG. 12, in the present embodiment, the moving image is continuously displayed until the reproduction is finished or a reproduction end instruction is issued, so that the user can continuously display the moving image in the display area R1. , The user can press the DISP button 15 at a desired timing to cut out some still images and display them in the display areas R2, R3,... To obtain a desired still image. Further, since the moving image display is not interrupted by cutting out the still image, it is easy to see and the still image can be edited in a short time.

  FIG. 13 is a flowchart for explaining the screen display operation of moving images and still images on the wide LCD screen in this embodiment. This flowchart is for explaining a program for causing the digital camera 1 to perform display / editing control of a reproduced image on the liquid crystal monitor screen of the wide LCD of the present invention.

  The following processing will be basically described by an example in which the CPU 41 is executed according to a program stored in advance in the program memory 42. However, it is not necessary to store all functions in the program memory 42. Alternatively, it may be realized by receiving all via a network. Hereinafter, description will be given with reference to FIGS.

  For the sake of explanation, it is assumed that moving image data recorded by moving image shooting and / or moving image data received from an external image processing apparatus is recorded in the format shown in FIG. : 9, the display area of the wide liquid crystal monitor screen 17 is set to display areas R1, R2, R3, and R4 as shown in FIG. 9B by default, and the aspect ratio of the display area R1 is 12: 9, Assume that the display areas R2, R3, and R4 have an aspect ratio of 4: 3, respectively.

  In the moving image reproduction mode, first, the CPU 41 executes a display area setting process as shown in FIG. 15 (step S0), and then reproduces and displays the moving image recorded in the storage medium 20 to be reproduced to the user. When the user is prompted to select a moving image and the user selects an image, the process proceeds to step S2. Here, the method of displaying the image so as to be selectable may be a known method. For example, representative image data (for example, the first still image data) is extracted from each moving image file recorded in the storage medium 20 and reduced, The desired moving image file may be selected by a two-dimensional array display on the liquid crystal monitor 17 and a cursor operation may be performed, or the grouped moving images or reduced images thereof may be displayed two-dimensionally on the liquid crystal monitor 17 and the cursor operation performed. A desired image may be selected (step S1).

  When a moving image to be reproduced is selected, the CPU 41 reads out the moving image data 201 of the selected moving image file 200 from the storage medium 20, performs an expansion process on each still image constituting the moving image data, reproduces it, and stores it in the image memory 35. (Step S2), the still images reproduced from the image memory 35 are sequentially read out one frame at a time and displayed continuously in the display area R1 (FIG. 9B) of the liquid crystal monitor 17 to display a moving image. At this time, it is assumed that the frame number counter (initial value = 0) is incremented by 1 to count the number of still images from the beginning (step S3).

  When a moving image is displayed, if there is an image to be cut, the user performs a still image cut instruction operation (depressing the DISP button 15 in the embodiment), so the CPU 41 operates based on a signal from the input circuit 51. In step S5, it is checked whether or not a still image cutting instruction operation has been performed. If a cutting instruction operation has been performed, the process proceeds to step S5. Otherwise, the process proceeds to step S9 (step S4).

  When the cut instruction operation is performed in step S4, a still image display process as shown in FIG. 16 is executed (step S5).

  When the still image is displayed in the display area, the user can perform a scroll operation or a replacement operation (in the embodiment, a front scroll operation or a rear scroll operation or a replacement operation using the cursor key 13 and the SET key 14). Checks whether or not a scroll operation or replacement operation has been performed on the operation input unit 50 based on a signal from the input circuit 51. If no scroll operation or replacement operation has been performed, the process proceeds to step S7, where the operation is performed. If it is, the process proceeds to a scroll process / replacement process as shown in FIG. In the present embodiment, the scroll process / replacement process is performed in parallel with the moving image display (that is, the moving image display is displayed continuously without being interrupted even during the scroll operation or the replacement operation), and the scroll process / replacement process is performed. As soon as the processed image ends, the process proceeds to step S7 (step S6).

  When the user wants to save and record the still image displayed in the display area, the user can specify the still image by cursor operation and save and record it in the storage medium 20. Therefore, the CPU 41 is based on the signal from the input circuit 51. It is checked whether or not an operation for designating the still image cut out by the operation input unit 50 has been performed. If the designation operation has been performed, the process proceeds to step S8, and if not, the process proceeds to step S9 (step S7).

  When a still image designation operation is performed in step S7, the CPU 41 reads from the image memory 35 based on the number of frames held in the data memory 43 (= the number of frames held in the still image display process of FIG. 16). The corresponding still image data is extracted, subjected to compression processing, and stored in the cut image recording area 20-5 (FIG. 6) of the storage medium 20. It should be noted that storage position information such as the number of still images cut out may be stored in the cut image recording area 20-5 (step S8).

  The CPU 41 checks based on a signal from the image input circuit 51 whether the moving image data to be reproduced has been completed or whether the operation input unit 50 has performed the reproduction end operation of the moving image. If the end operation has been performed, the display process is ended, and if not, the process returns to step S2 (step S9).

  With the operation shown in the flowchart of FIG. 13, the digital camera 1 can set a region for displaying a moving image on the storage medium 20 and a region for displaying a still image cut out from the moving image. The area can be used effectively. Further, since the moving image display area and the still image display area are different, the cut still image does not overlap the moving image, so that the moving image and the still image are easy to see.

  Also, since the displayed still image can be scrolled back and forth, the images before and after the corresponding still image in the video data can be sequentially cut out and displayed, so that the timing of the still image cutting has shifted. Even in such a case, a desired still image can be acquired by re-cutting a still image from a moving image. Even if the currently displayed moving image and the clipped still image are significantly different from each other, the desired still image can be acquired by cutting out the previous or subsequent image corresponding to the still image.

  In addition, since the moving image can be displayed in the display area of the clipped still image and the moving image can be displayed in the display area of the moving image, the still image is displayed when the displayed still image is difficult to see. You can enlarge the image.

FIG. 14 is a diagram showing an embodiment of the display area setting screen. Reference numeral 140 is a display area setting screen, reference numeral 141 is a standard setting window, reference numeral 142 is a user setting window, reference numeral 143 is a standard setting selection field, reference numeral Reference numeral 144 denotes a user setting selection field, and reference numeral 13 denotes a cursor.
The standard setting window 141 displays a moving image display area R1 having an aspect ratio of 12: 9 and still image display areas R2, R3, and R4 having an aspect ratio of 4: 3 shown in FIG. 9B. When the user operates the cursor key 13 to position the cursor 13 in the standard setting selection field 143 and presses the SET key 14, the standard setting is selected.
In the user setting window 142, the moving image display region R1 is displayed in the center, and the left and right are displayed in color as margin portions where the display region is set by the user. When the user operates the cursor key 13 to position the cursor 13 in the user setting selection field 143 and press the SET key 14, the user setting is selected (refer to the route from step S0-4 to S0-6 in FIG. 15).

FIG. 15 is a detailed flowchart for explaining the display area setting processing operation of the flowchart of FIG.
In FIG. 15, the CPU 41 asks the liquid crystal monitor 17 whether or not it is necessary to set the display area (for example, do you set the size and position of the image to be displayed on the screen? (A) set, (B) set by the user, (C) Not set) is displayed and the user is prompted to select by operating the cursor key 13 (step S0-1). When the user selects “(a) set”, the display area setting flag is turned on (value = “ 1 ”), the process proceeds to step S0-3. If“ (B) already set ”is selected, the process proceeds to step S1, and if“ (C) not set ”is selected, the display area setting flag is turned off (value =“ 0 ”). ”) And the process proceeds to step S1 (step S0-2).

  When setting the display area, the CPU 41 displays a display area setting screen 140 as shown in FIG. 14 (S0-3), prompting the user to select whether the standard setting is acceptable or not, and the standard setting is selected. If YES in step S0-5, the flow advances to step S0-5. If user setting is selected, the flow advances to step S0-7 (step S0-4).

  When the standard setting is selected, the CPU 41 takes out the standard setting values recorded in the data memory 43 (or the program memory 42) and sets the standard setting areas R1, R2, R3, R4 in the VRAM 48, and the steps shown in FIG. Proceed to S1 (step S0-5).

  When the user setting is selected, the CPU 41 displays the cursor 13 on the liquid crystal monitor screen 17, enables the user to operate the cursor, and moves the cursor 131 by operating the cursor key 13 to move the display region R1. Alternatively, the display area is set in the margin. For example, in the display area R1, the cursor 13 is positioned at the right end or the left end of the display area R1 of the user setting window 142, the SET key 14 is pressed, and the cursor key 13 is operated to move right (→) or left (←). Can be moved left and right. Further, the cursor 13 is positioned at the right or left end of R1 or the upper or lower end of the window 172 in an area other than the display area R1 (that is, a blank portion), and the cursor key 13 is moved left and right (→ ) (←) Move operation or up / down (↑) (↓) move operation to move the cursor 131 and press the SET key 14 to divide the area other than the display area R1, for example, FIG. As shown in FIG. 9C, display areas R2 and R3 can be set.

  The CPU 41 examines a signal from the operation input unit 50, acquires an area setting value corresponding to the cursor operation (step S0-7), sets a user setting area in the VRAM 48, and proceeds to step S1 (step S0-8).

  FIG. 16 is a detailed flowchart for explaining the still image display processing operation in the flowchart of FIG. 13. In step S4 of the flowchart of FIG. 13, a still image cutting instruction operation for the moving image displayed in the display area R1 is performed. The still image display processing operation performed in the case where the For the sake of explanation, four display areas R1 to R4 are set, and R1 is described as a moving image display area and R2 to R3 as still image display areas. In addition, the initial values of the display flags R2, R3, and R4 are turned off (= “0”). If the set display area is smaller or larger than R1 to R4, intermediate steps for still image display according to the following steps S5-5 to S5-7 may be added or reduced.

  In FIG. 16, when a cut instruction operation is performed in step S4 of the flowchart of FIG. 13, the CPU 41 receives the DISP button depressing signal from the input circuit 51 when the cut instruction is given (in the embodiment, the DISP button 15 is pressed). CPU 41 receives the frame number of the image displayed in the moving image display area R1 (step S5-1), extracts the corresponding still image from the image memory 35 based on the acquired frame number, and displays the display area The image is reduced and held to fit the size of R2 (step S5-2). Next, the display flag of the display area R2 is examined. If the display flag is on, it is determined that a still image is displayed on R2, and the process proceeds to step S5-5. If it is off, the process proceeds to step S5-4 ( Step S5-3).

  When the display flag of the display area R2 is OFF, the still image held in step S5-2 is displayed on the display area R2, and the process proceeds to step S6 in FIG. Further, it is assumed that information indicating the number of frames of the still images displayed on R2, R3, and R4 is held in association with each display area (step S5-4).

  If the display flag of the display area R2 is on, the CPU 41 checks the display flag of the display area R3. If the display flag is on, the CPU 41 determines that a still image is displayed on the R3, and proceeds to step S5-8. If it is off, the process proceeds to step S5-6 (step S5-5).

  When the display flag of the display area R3 is OFF, the CPU 41 displays the still image displayed in the display area R2 on the display area R3 (step S5-6), and then the still image reproduced in step S5-2. The image is overwritten on the display area R2, and the process proceeds to step S6 in FIG. Further, it is assumed that information indicating the frame number of the still image displayed on R2, R3, and R4 is held in association with each display area (step S5-7).

  When the display flag of the display area R3 is ON, the CPU 41 overwrites and displays the still image displayed in the display area R3 on the display area R4 (step S5-8), and the still image displayed in the display area R2 Is overwritten in the display area R3, and then the process proceeds to step S5-7. Further, it is assumed that information indicating the number of frames of the still images displayed in R2, R3, and R4 is held in association with each display area (step S5-9).

  FIG. 17 is a detailed flowchart for explaining the still image scroll processing / replacement processing operation in the flowchart of FIG. 13, and shows the processing operation performed when the operation is performed in step S6 of the flowchart of FIG. . For the sake of explanation, four display areas R1 to R4 are set, and R1 is described as a moving image display area and R2 to R3 as still image display areas.

  In FIG. 17, the CPU 41 substitutes the number of frames (counter value at step S2 of the flowchart of FIG. 13) counted at step S2 of the flowchart of FIG. 13 into the scroll counter (step T1). It is checked whether the operation of step S6 in the flowchart of FIG. 13 is the front scroll operation, the rear scroll operation, or the replacement operation. If the operation is the front scroll operation, the process proceeds to step T3. Advances to step T13 (step T2).

  In the case of the previous scroll operation, the CPU 41 overwrites and displays the still image displayed in the display region R3 on the display region R4 (step T3), and overwrites and displays the still image displayed on the display region R3 on the display region R4. Then (step T4), 1 is subtracted from the scroll counter value (step T5), and the still image data of the number of frames indicated by the scroll counter value is extracted from the image memory 35 so as to fit the size of the display area R2. (Step T6), overwritten in the display area R2, and proceeds to step T20. Further, it is assumed that information indicating the number of frames of the still image displayed in the display areas R2, R3, and R4 is held in association with each display area (step T7).

  In the case of the rear scroll operation, the CPU 41 overwrites and displays the still image displayed in the display region R3 on the display region R2 (step T8) and overwrites the still image displayed on the display region R4 on the display region R3. Then (step T9), the CPU 41 adds 1 to the value of the scroll counter (step T10), takes out still image data of the number of frames indicated by the value of the scroll counter from the image memory 35, and sets the size of the display area R4. The image is reduced so as to fit (step T11), overwritten in the display area R4, and the process proceeds to step T20. Further, it is assumed that information indicating the frame number of the still image displayed in the display areas R2, R3, and R4 is held in association with each display area (step T12).

  In the case of the replacement operation, it is checked whether the still image specified by the cursor key is a still image displayed in one of the display areas R2, R3, and R4 or a still image displayed in the display area R1. If it is a still image displayed in any of the regions R2, R3, R4, the process proceeds to step T14, and if it is a still image displayed in the display region R1, the process proceeds to step T17 (step T13).

  In the case where the specified image is a still image displayed in any of the display areas R2, R3, and R4, the number of frames indicating the frame number of the still image displayed in the specified display area (Step T14), the still image data of the number of frames is taken out from the image memory 35 and displayed in the display area R1 (step S15), and the moving image data stored in the image memory 35 is switched from the moving image data. The still image data having the number of frames is taken out and reduced so as to fit the size of the designated display area, and the frames are continuously displayed one by one in the display area (moving image display), and the process proceeds to step T20. Further, it is assumed that information indicating the number of frames of the still image displayed in the display area R1 is held in association with the display area R1 (step T16).

  If the designated image is a still image displayed in the display area R1, the number of frames of the still image is acquired (step T17), and the still image data of the number of frames is extracted from the image memory 35 and a moving image is obtained. Is reduced to fit in the size of the display area where the image is displayed and overwritten in the display area (step T18), and the continuation image of the moving image displayed in the display area is taken out from the image memory 35 and displayed. It displays in area | region R1 (step T19).

  Based on the signal from the input circuit 51, the CPU 41 checks whether or not a scroll operation or replacement operation has been performed at the operation input unit 50. If a scroll operation or replacement operation has been performed, the CPU 41 returns to step T2, and a predetermined time has elapsed. However, if the scroll operation or the replacement operation is not performed, the process proceeds to step S7 in FIG. 13 (step T20).

[Embodiment 2]
In the first embodiment, even if there is a switching instruction or a scroll instruction / replacement instruction during the moving image display, the moving image display (continuous display of still images of each frame constituting the moving image) is performed without interruption. If there is a switching instruction during display, the moving image display may be interrupted and still image switching processing may be performed, and a scroll instruction / replacement instruction may be performed as necessary.

  FIG. 18 is a timing chart for displaying a moving image and a still image on the wide LCD screen according to the present embodiment. The moving image start timing, the cutout instruction for the still image A (depressing the DISP button 15), the timing for the moving image restart instruction, The cutout instruction timing of image B, the instruction of moving image resumption instruction, and the cutout timing of still image C are recorded in time series, and the horizontal axis represents the moving image display period (black band portion) and moving image (moving image) in the display region R1, respectively. Still images constituting data), display periods of the cut out still images A, B, and C in the display region R2, transition of the still images (A, B, and C) displayed in the display region R2, and cut out in the display region R3 The display period of the still images A, B,... Displayed, and the transition of the still images (A, B,...) Displayed in the display region R3 are shown.

  In the present embodiment, as shown in FIG. 18, the reproduced video is continuously displayed in the display area R1 until a switching instruction is issued, or reproduction is finished or a reproduction end instruction is issued, and a moving picture restart instruction is issued. Video display resumes.

  In FIG. 18, when a switching instruction, that is, the DISP button 15 is pressed during moving image display, the still image A is cut out and displayed in the display area R2, and the moving image display is interrupted. Next, when the DISP button 15 is pressed after the moving image display is restarted by the moving image restart instruction, the still image B is cut out and displayed in the display region R2 and the still image A is displayed in the display region R3, and the moving image display is performed. Is interrupted. When the DISP button 15 is pressed after the moving image display is restarted by the moving image restart instruction, the still image C is cut out and displayed in the display region R2 and the still image B is displayed in the display region R3. The still images A, B, and C are displayed in the display area R2 until the next DISP button 15 is pressed, and sequentially displayed in the display area R3 when the DISP button 15 is pressed.

  As shown in the timing chart of FIG. 18 above, in this embodiment, when a still image cut instruction is issued, the moving image display is interrupted, so that the user carefully looks at the still images displayed in the display areas R2 and R3. In addition, a desired still image can be acquired while performing a scroll process or a replacement process with a sufficient time.

  FIG. 19 is a flowchart for explaining the screen display operation of moving images and still images on the wide LCD screen in this embodiment. This flowchart is for explaining a program for causing the digital camera 1 to perform display / editing control of a reproduced image on the liquid crystal monitor screen of the wide LCD of the present invention.

  The following processing will be basically described by an example in which the CPU 41 is executed according to a program stored in advance in the program memory 42. However, it is not necessary to store all functions in the program memory 42. Alternatively, it may be realized by receiving all via a network. Hereinafter, description will be made based on FIGS. 1 to 11, 18, and 19.

  For the sake of explanation, it is assumed that moving image data recorded by moving image shooting and / or moving image data received from an external image processing apparatus is recorded in the format shown in FIG. : 9, the display area of the wide liquid crystal monitor screen 17 is set to display areas R1, R2, R3, and R4 as shown in FIG. 9B by default, and the aspect ratio of the display area R1 is 12: 9, Assume that the aspect ratios of the display areas R2, R3, and R4 are 4: 3, and the operations in steps S1 to S4 are the same as those in the flowchart of FIG.

  When the cut instruction operation is performed in step S4 (see FIG. 13), the CPU 41 stops the moving image display by reading the moving image data from the image memory 35 and blocking the display path to the moving image display area R1. (Step S5-1), the cut still image display process as shown in FIG. 16 is executed (Step S5-2).

  When the still image is displayed in the display area, the user can perform a scrolling operation or a switching operation (in the embodiment, a front scrolling operation or a rear scrolling operation or a switching operation using the cursor key 13 and the SET key 14). Checks whether or not a scroll operation or replacement operation has been performed on the operation input unit 50 based on a signal from the input circuit 51. If no scroll operation or replacement operation has been performed, the process proceeds to step S7, where the operation is performed. If YES in step S6-2, the flow advances to step S6-2 (step S6-1).

  When a scroll operation or a replacement operation is performed, a scroll process / replacement process as shown in FIG. 17 is executed. If there is an exchange operation, the moving image displayed in steps T16 and T17 in FIG. 17 is an image when the moving image display is stopped (step S6-2).

  When the user wants to save and record the still image displayed in the display area, the user can specify the still image by cursor operation and save and record it in the storage medium 20. Therefore, the CPU 41 is based on the signal from the input circuit 51. It is checked whether or not an operation for specifying the still image cut out by the operation input unit 50 has been performed. If the specifying operation has been performed, the process proceeds to step S8-2, and if not, the process proceeds to step S9 (step S7).

  When a still image designation operation is performed in step S7, the CPU 41 reads from the image memory 35 based on the number of frames held in the data memory 43 (= the number of frames held in the still image display process of FIG. 16). The corresponding still image data is taken out, subjected to compression processing, and stored in the cut image recording area 20-5 of the storage medium 20. It should be noted that storage position information such as the number of still images cut out may be stored in the cut image recording area 20-5 (step S8-1).

  The CPU 41 reads the moving image data from the image memory 35 and opens the display path to the moving image display area R1 to resume from the image of the frame for which the moving image display is stopped (interrupted) (step S8-2).

  The CPU 41 checks whether or not the moving image data to be reproduced has ended, or whether or not the moving image reproduction end operation has been performed by the operation input unit 50 based on the signal from the image input circuit 51, and whether the moving image data has ended or the signal from the image input circuit 51 If the operation input unit 50 performs a moving image reproduction end operation based on the above, the display process ends, otherwise the process returns to step S2 (step S9).

  The same effects as those of the first embodiment can be obtained by the operation shown in the flowchart of FIG. In addition, when the still image is cut out and displayed in the still image display area, the moving image display is stopped, so that the user can view the still image displayed in the display area with sufficient time, or perform a desired still image by scrolling or the like. A picture can be acquired.
