Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-screen display system for displaying reproduced images on a multi-screen in an electronic still camera system. The present invention relates to a multi-screen display system capable of displaying an image on one multi-screen. 2. Description of the Related Art In an electronic still camera system, when comparing images recorded on different floppy disks, a method of replacing a floppy disk, a method of using a plurality of reproducing systems, and editing a floppy disk have conventionally been used. You were going in one of the ways. FIG.
(a) is for explaining a method of replacing a floppy disk. First, the first floppy disk A is mounted on the reproducing device 31 and an image is displayed on the monitor 30 to learn the contents of the image. Then, the floppy disks are replaced, and the images on the floppy disk B are reproduced for comparison. FIG. 4B is a diagram for explaining a method of using a plurality of playback systems. Two playback systems including a playback device 34 and a monitor 32 and two playback devices 35 and a monitor 33 are prepared. The disk A is inserted into the playback device 35 with the floppy disk B inserted, and the images are compared. Also,
FIG. 4C illustrates a method of editing a floppy disk. The contents of the floppy disks A and B are edited in advance and combined into one floppy disk, reproduced by the reproducing device 37, and displayed on the monitor 36. In this multi-screen display, an image recorded on the floppy disk A and an image recorded on the floppy disk B are compared first. [0003] In the above comparison method, the method shown in FIG. 4 (a) can memorize the degree of feeling of an image, but it is difficult and accurate to memorize small parts. Comparisons are difficult. In the method shown in FIG. 4 (b), a plurality of reproduction systems must be prepared, so that the economic burden is increased and the space for setting the system must be secured widely. Further, the method of FIG. 4 (c) has a problem that dubbing and editing on one floppy disk requires an operation, and furthermore, deterioration of image quality cannot be avoided. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a multi-screen display system capable of comparing images recorded on two recording media accurately and easily. In order to achieve the above object, a multi-screen display system between different recording media according to the present invention is a multi-screen display for displaying a reproduced image in a multi-screen in an electronic still camera system. In the system, a multi-screen memory for storing each image in a recording medium for displaying a multi-screen, and an image capturing unit that captures a plurality of images recorded on a recording medium into the multi-screen memory, An image selecting unit for selecting an image to be displayed on the multi-screen from among the images stored in the multi-screen memory; and an image capturing unit from the first recording medium to the multi-screen memory. When an image is captured and an image is selected by the image selection means, only that image is stored in the multi-screen memory.
In the storage area for comparison with the contents of the second recording medium.
When the second recording is performed from the first recording medium.
A plurality of images recorded on the second recording medium by interchanging the recording medium taken into the multi-screen memory, before
Taking an image of the second recording medium from the first recording medium;
The image is displayed sequentially from the next screen of the loaded image, and when the image feed operation is performed , the image is taken out from the first recording medium.
Control means for erasing the image displayed on the screen next to the loaded image and moving up the subsequent images one by one and displaying them. Hereinafter, the present invention will be described in more detail with reference to the drawings and the like. FIG. 1 is a diagram showing a state in which images in different floppy disks are multi-displayed using the multi-screen display system according to the present invention. First, the floppy disk A is inserted into the reproducing device 22 to multi-display the images in the floppy disk A, and the image of the house (a) displayed on the screen of the monitor 21 is stored. Next, the floppy disk B is inserted, and the images in the floppy disk B are multi-displayed. Then, by selecting the images of the house (b) and the trees (c) and (d), the floppy disk A is displayed on the monitor 21 as shown in FIG.
And B images can be mixed and displayed in multi-
Comparison becomes easy. If another image of floppy disk B is selected in this state, the image of the house (b) disappears,
(C) The images of (d) are displayed in order and the selected image is inserted into the last screen of the multi-screen. FIG. 2 is a block diagram showing an embodiment of a multi-screen display system according to the present invention. First, the configuration and operation of the recording-side circuit will be described. Light from a subject (not shown) is condensed by a lens 5, the exposure amount is adjusted by an aperture 6, and then an image is formed on a CCD 7. The signal processing circuit 9 is C
The electrical signal photoelectrically converted by the CD 7 is processed to create a video signal (luminance signal, color difference signal, synchronization signal, etc.). The aperture / CCD control circuit 8 sends an aperture control signal and C
A CD control signal is sent out, the aperture 6 is controlled so as to obtain an appropriate exposure, and the CCD 7 is scanned at a predetermined timing. Further, a part of the luminance signal is sent to a CPU and a system control circuit (hereinafter, referred to as a “control circuit”) 1, and a focus control signal is generated from the information. The control circuit 1 sends a focusing control signal to the lens driving unit 4 to drive the lens so that the subject image is focused on the CCD 7. On the other hand, the control circuit 1 controls the head drive circuit 11 to move the head 23 to an empty track. Further, the servo control and drive circuit 12 is driven to control the floppy disk 13 to rotate at a constant speed. The video signal of the signal processing circuit 9 is stored in a recording / erasing circuit 10.
Is recorded on the floppy disk 13 by the head 23. The control circuit 1 is a key input circuit 2
Shooting and playback control are performed by key operation input from. The display unit 3 performs display in each operation process based on the control of the control circuit 1. Next, the configuration and operation of the reproducing circuit will be described. When there is an instruction for an image to be reproduced from the key input circuit 2, the control circuit 1 controls the drive of the head drive circuit 11 to move the head 23 to a track based on the instruction. The reproduction circuit 14 demodulates the FM modulated wave read from the head 23. Then, it performs predetermined processing to reproduce and output the video signal. When the floppy disk 13 is mounted, the control circuit 1 automatically seeks all the tracks and takes each image of the floppy disk 13 into a multi-screen block. The multi-screen block includes an A / D converter 19, an erasure display data section 16, a switch 20, a memory 17, a D / A converter 18, and a memory control circuit 15. A demodulated signal (video signal) of each track read from the floppy disk 13 and demodulated by the reproducing circuit 14 is converted into a digital signal by the A / D converter 19. On the other hand, the control circuit 1 includes a memory control circuit 15
Sends the address corresponding to the track from which the image was read. As a result, the memory control circuit 15 has A /
The D-converted image is stored in the designated address space of the memory 17 via the switch 20. When reading a multi-screen, the memory control circuit 15 reads the contents in the memory 17 based on an instruction from the control circuit 1. After being converted into an analog signal by the D / A converter 18, the signal is reproduced by a monitor or the like (not shown) via the reproduction circuit 14. FIG. 3 is a flowchart for displaying images of two floppy disks on one multi-screen using the multi-screen display system according to the present invention.
A main switch (not shown) is turned on (step 301).
Then, the control circuit 1 determines whether or not the floppy disk 13 is mounted (step 302). When the floppy disk 13 is not mounted, a warning process is performed. When it is determined that the floppy disk 13 is mounted, the head 23 is caused to seek from 1 to 50 tracks to determine whether or not there is an image on each track. Check for breaks, etc.
Multi-image capture is performed (step 303). The user selects a mode (normal one-screen reproduction mode or multi-screen display) using the mode selection key-2a of the key input circuit 2 (step 304). In response to this operation, the control circuit 1 determines whether or not the multi-screen display mode has been selected (step 305). In the case of normal reproduction, the mode shifts to another mode, and when the multi-display mode is selected, the next image to be stored is selected (step 306). The selected image is stored in the storage area 17a of the memory 17 (Step 307). Then, the control circuit 1 determines whether or not an operation for storing another image has been performed (step 308). If an operation to be stored has been performed, the process returns to step 306 to select the next image. Thus, the image on the floppy disk A can be selected. On the other hand, if the operation to be stored has not been performed, it is next determined whether or not to compare with an image on another floppy disk. If the comparison key-2b is operated in advance, the mode shifts to the comparison mode. If the comparison key-2b is not operated, the flow returns to the mode selection of step 304. When the mode is shifted to the comparison mode, the floppy disk A is removed next, and the floppy disk B is mounted instead (step 310). When the floppy disk B is mounted, the control circuit 1 sets the head 23 to 1 to 5
It seeks to track 0, checks the presence / absence of an image on each track, checks for claw breaks, and takes in multiple images (step 311). [0012] Thereafter, the user operates the multi-screen number setting key.
The number of screens is set by 2c (step 312). Further, the order of the comparison screen is set by selecting an image to be compared with the comparison screen selection key-2d (step 313). The control circuit 1 obtains the information of image selection from the key input circuit 2 so that the memory control can be performed.
Instruct the memory circuit 15 to read out the contents of the memory 17 in the order of selection and display a multi-screen. Thus, on the monitor (not shown), for example, as shown in FIG. 1, the image of the house (a) of the floppy disk A is displayed at the beginning of the multi-screen, and the subsequent screens are displayed in the order selected by the floppy disk B (b). A multi-screen in which the images (c) and (d) are displayed in order is reproduced (step 314). Next, the control circuit 1 determines whether or not an operation for sending the image selected on the floppy disk B has been performed by the image sending key-2e (step 315). If the image feed operation has not been performed, the operation of the multi-image display ends (step 317). If the image feed operation has been performed, a multi-image feed operation is performed (step 3).
16). The multi-image feed operation means that, of the images selected from the floppy disk B in FIG. 1, the image (b) is erased, and the images (c) and (d) thereafter are moved up one by one, and the other images are already selected. Is displayed on the last screen of the multi-screen. After performing the multi-image feed operation, the process returns to step 314 to display the multi-screen which has been multi-image fed. This multi-image feed operation can be repeatedly performed in steps 314, 315 and 316. As described above, the present invention provides:
Since images in different recording media can be displayed on the same multi-screen, there is an advantage that images can be compared on a multi-screen in which images in a plurality of floppy disks are mixed. Also, while the image in one recording medium is stored in the memory, the multi-screen in which the image is displayed at a predetermined position of the multi-screen can be displayed at any time.
Further, it is not necessary to edit the images in a plurality of floppy disks into one floppy disk, and it is possible to compare the images in the plurality of floppy disks without deteriorating the image quality.
