It is used as a viewfinder, and in playback mode, it is used as playback display means for reading out and playing back images that have been picked up and recorded.

  Also, in an imaging apparatus equipped with an imaging device such as a digital camera, the captured subject image is often stored as image data in a storage medium such as a memory card. In addition to the image data, the memory card stores settings input in advance by the user and various information data recorded during imaging.

  On the other hand, when the playback mode is selected on the digital camera, as a method for displaying an image on the display unit, generally, there are a full screen display for displaying one image on the entire screen of the display unit, and a number of screens on the display unit. A display method called multi-screen display in which a plurality of images are displayed in such a small screen is representative. In the full screen display, the image data stored in the memory card is read one by one in order, and the image is displayed on the entire screen of the display unit. When the user operates a cursor button or the like, instead of the reproduced image displayed so far, the images in the order before and after the read image are read out and displayed on the entire screen of the display unit. When such a selection operation is repeated, the image display is switched one by one, and the user can search for a desired image.

  On the other hand, in the case of multi-screen display, a plurality of image data are read from the memory card at a time, and these images are respectively displayed on the small screen of the display unit. When there is an image that you want to see details in the multi-screen display image, select the image with the cursor button etc., and you can check the details by enlarging and displaying only that image. .

  FIG. 4 is a block diagram showing an electrical configuration of the digital camera 2. Behind the imaging lens 10 is disposed a solid-state imaging device 41 composed of a CCD image sensor, a CMOS image sensor, or the like. The subject light transmitted through the imaging lens 10 is converted into an imaging signal by the solid-state imaging device 41. The solid-state imaging device 41 is connected to a CPU 44 that controls the entire digital camera 2 via a driver 42 and a timing generator 43. The CPU 44 controls the driver 42 and the timing generator 43 to drive the solid-state imaging device 41.

  The imaging signal output from the solid-state imaging device 41 is input to a correlated double sampling circuit (CDS) 45. The CDS 45 outputs the imaging signal input from the solid-state imaging device 41 as R, G, and B image data that accurately corresponds to the accumulated charge amount of each cell of the solid-state imaging device 41. Image data output from the CDS 45 is amplified by an amplifier (AMP) 46. The A / D converter 47 converts the image data amplified by the AMP 46 into digital image data. The digital image data output from the A / D converter 47 is transmitted to the image signal processing circuit 48.

  The image signal processing unit 48 is connected to the CPU 44 via the data bus 49. The CPU 44 controls the image signal processing unit 48 to perform various image processing such as gradation conversion, white balance correction, and γ correction processing on the image data. Further, a video memory 50 and a buffer memory 51 are connected to the image signal processing unit 48 via a data bus 49. The video memory 50 temporarily stores low-resolution image data sent from the image signal processing unit 48 when the color display unit 21 is used as an electronic viewfinder. The image data recorded in the video memory 50 is transmitted to the LCD drivers 52 and 53 via the data bus 49 and displayed on the color display unit 21. The buffer memory 51 temporarily records captured high resolution data. The image data read from the buffer memory 51 is compressed by a compression method such as JPEG by the compression / decompression processing unit 54 connected via the data bus 49. The compressed image data is recorded on the memory card 17 by the CPU 44 controlling the media controller 55.

Further, the release button 13, the mode dial 14, and the operation unit 23 are connected to the CPU 44. The CPU 44 acquires a command from the user by operating the release button 13, the mode dial 14, and the operation unit 23. When the recorded image reproduction command is acquired from the user, the CPU 44 controls the media controller 55 to read out the image data from the memory card 17. The CPU 44 can display the expanded image data on the display units 22 and 21 by controlling the LCD drivers 52 and 53. When the multi-screen display is performed on the monochrome display unit 22 as described above, a plurality of image data is displayed. Are read out, and the respective image data are displayed in the small screens 22a to 22i in which the screen of the monochrome display unit 21 is divided. Further, the CPU 44 can display various menu screens and setting contents on the two display units 22 and 21 via the LCD drivers 52 and 53.

  Further, the recording microphone 56 and the speaker 28 are connected to the CPU 44 via an audio signal processing circuit 57, and the CPU 44 sequentially converts A / D conversion of audio input by the recording microphone 56 by the audio signal processing circuit 57. And converted into audio data by various signal processing and written to the memory card 17. At the time of reproduction, the audio data written in the memory card 17 is D / A converted again by the audio signal processing circuit 57 and output from the speaker 28.

  The operation of the above configuration will be described based on the flowchart of FIG. First, when the playback mode is selected with the mode dial 14, the image 65 recorded on the memory card 17 is read out on the color display unit 21 and displayed on the color display unit 21 on the full screen, and on the monochrome display unit 22. Then, information display such as imaging information and file number when the image 65 is captured (state shown in FIG. 3A) is performed. When the changeover switch 26 is slid, the monochrome display unit 22 is switched to a multi-screen display in which the screen is equally divided into nine small screens 22a to 22i and images are respectively displayed on the small screens 22a to 22i. (State shown in FIG. 3B). At this time, the images 61 to 64 and 66 to 69 recorded in the order before and after the image 65 are read from the memory card 17 together with the image 65, and are displayed on the small screen 22 e located at the center of the monochrome display unit 22. The image 65 is displayed, the images 61 to 64 positioned in the order before the image 65 are on the small screens 22a to d, and the images 66 to 69 positioned in the order after the image 65 are on the small screens 22f to i. Each is displayed in order. When the cursor operation button 25 is pressed, the image displayed on the full screen on the color display unit 21 is sequentially switched one frame at a time. At the same time, the image displayed on the monochrome display unit 22 is also displayed on the center small screen. 22e is switched to the same image as the color display unit 21, and the images on the small screens 22a to 22d and the small screens 22f to 22i are also sequentially switched to the images in the order before and after that. When a desired image is displayed on the color display unit 21, when the changeover switch 26 is slid to return the display content of the monochrome display unit 22 to the information display, each process (deletion and writing prohibition) is performed on the image data of the display image. Voice memo recording / playback). When each process is executed and another image is desired to be searched, the monochrome display unit 22 can be switched to the multi-screen display again to select an image, and then returned to the information display to execute each process on the image data.

  In this way, the color display unit 21 displays an image in full screen display, and the monochrome display unit 22 displays a plurality of images in a multi-screen display together with the previous and subsequent images. An operation such as searching for a desired image or selecting the image and executing each process on the image data is easy, and the color display unit 21 displays the image in full screen. It is easy to see up to. Furthermore, since the monochrome display unit 22 and the color display unit 21 are arranged vertically on the same surface of the camera body 3, it is easy to view the full screen display and the multi-screen display at the same time.

  In the first embodiment, the changeover switch 26 is provided as a switching means for switching the display content of the monochrome display unit 22. However, the present invention is not limited to this. For example, the cursor operation button 25 also serves as the switching means. You may do it. That is, as shown in FIG. 6, when the user presses the cursor operation button 25 to the right or left, the CPU 44 changes the display content of the monochrome display unit 22 from the information display (the state shown in FIG. 6A) to the multi-screen. The display is switched to the state shown in FIG. 6B, and at the same time, one frame advancement of the image is started. At this time, in the multi-screen display of the monochrome display unit 22, the number of images that can be displayed in one column, for example, three small screens 22j to 1 are arranged in the screen, and the color display unit is displayed on the central small screen 22k. When the cursor operation button 25 is pressed to the right side (shown in the figure), the same image 65 as that 21 is displayed, the images 64 and 66 in the order before and after that are displayed on the small screen 22k and the small screen 22l, respectively. When the small screens 22j to l scroll in the A direction and are pressed to the left side, the small screens 22j to l may be scrolled to the left side (B direction in the figure). When the user releases the cursor operation button 25, the monochrome display unit 22 switches to information display and stops frame advancement of images.

In the above embodiment, the display content of the monochrome display unit 22 is switched between information display and multi-screen display, thereby improving the operability of the image selection process for searching for a desired image and making it easier to grasp the order of the images. However, the present invention is not limited to this. For example, as shown in FIG. 7, the display content of the monochrome display unit 22 is switched between information display (state shown in FIG. 7A) and order display (state shown in FIG. 7B). May be. That is, in the order display of the monochrome display unit 22 shown in FIG. 7B, the order display bar 71 located at the center of the screen indicates the position of the display image currently displayed on the color display unit 21. This bar 71 is a horizontally long bar-shaped figure that indicates the number of all images recorded on the length L _ALL memory card 17 in the longitudinal direction, and is different in color at a boundary line 71a in the middle in the longitudinal direction. The length L _N from the left edge 71 b to the boundary line 71 a in the drawing is the position of the display image currently displayed on the color display unit 21. Thereby, it is possible to grasp at a glance the order in which the current display image is located with respect to all the images. Also, by grasping the order of the display images, it becomes easy to search for a desired image. In FIG. 7B, the space other than the rectangular portion 72 at the center of the screen where the order display bar 71 is displayed on the monochrome display unit 22 has the same contents as when displaying information, but this is not restrictive. For example, all the spaces other than the order display bar 71 may be displayed in a single color such as black.

  In the above-described embodiment, full-screen display on the color display unit 21 and multi-screen display on the monochrome display unit 22 are performed at the same time. However, the present invention is not limited to this, and as shown in FIG. 8, when an enlargement / reduction operation is input, the monochrome display unit 22 reproduces the image. The displayed image 65 may be displayed in full screen, and the color display unit 21 may display an enlarged / reduced image in which an image 75 obtained by enlarging / reducing a part of the image 65 is displayed. In this case, an enlarged / reduced image obtained by enlarging / reducing at least a part of the image is created by the image signal processing unit 48. In this case, the cursor operation button 25 can also serve as a display content switching unit and an enlargement / reduction ratio input unit. That is, when the user presses the cursor operation button 25 to the right or left, the CPU 44 changes the display content of the monochrome display unit 22 from the information display (FIG. 8A) to the full screen display of the image 65 (FIG. 8B). ), The color display unit 21 switches from full screen display (FIG. 8A) to enlarged / reduced image display (FIG. 8B), and simultaneously starts enlarging / reducing the image. At this time, for example, immediately after switching, for example, the color display unit 21 and the monochrome display unit 22 display the same size, and then the cursor operation button 25 is continuously pressed to the right, so that only the central portion of the image is enlarged. It is displayed and reduced by continuing to press to the left. When the user releases the cursor operation button 25, the monochrome display unit 22 is switched to information display, and the enlargement / reduction of the image on the color display unit 21 is also stopped.
