Abstract

PURPOSE:To prevent previously the titled device from defects such as the recording of unnecessary pictures and misarrangement of pictures by extracting the picture elements of picture data stored and arrayed in a plural-picture storage part and displaying a synthesized picture compressed by an extracting means. CONSTITUTION:When only one frame is to be displayed on a display device by controlling a controller 9, the picture elements of an address similar to that of writing are read out from the plural-picture storage part 3 and displayed on the display device such as a CRT12 through a D/A converter 10 and an amplifier 11. If the outputs of an X-address counter 4 and a Y-address counter 5 are invalidated by one bit, the least significant digits of the output of the counters 4, 5 are fixed to ''0'' or ''1'' and only even addresses or odd addresses are obtained, so that the addresses in the plural-picture storage part 3 are alternately extracted and the shown pictures H1-H4 are displayed on the CRT12. Since the number of picture elements in the CRT12 is small, a synthesized picture having 1/4 picture element density obtained by thinning the picture elements alternately in the X and Y directions is displayed as shown in the drawing.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image recording device having a function of selectively displaying a plurality of pieces of image data stored in a storage unit on a display device.

A conventional multi-format camera is a so-called CRT photographing device, in which an image arrangement is programmed when recording multiple images, and each image is processed by CR according to the program.
The images are output one by one to the T, and are photographed as hard copies using film through a lens optical system. In this case, since multiple images are recorded one by one, for example, one
Once an individual image is recorded, it is impossible to change it. Furthermore, there are many disadvantages in use, such as the inability to change the image arrangement midway through recording, and the fact that it is difficult to tell what kind of image has been recorded unless it is a hard copy.

Figure 1 shows an example in which four frames of images F1 to F4 are arranged on one hard copy.In conventional equipment, image F1 is first output to a CRT and photographed, and then image F2 is output to the same CRT. Four frames of images Fl-F4 are sequentially recorded by outputting and photographing. Therefore, for example, if you realize that another image should be recorded at image F2 after shooting image F2, or if you realize that image F2 should be arranged at the position of image F3, , the shooting would have to be redone and the hard copy would be wasted. In addition, a multi-format camera may arrange not only the image arrangement shown in FIG. 1, but also six frames of images F1 to F6 as shown in FIG. 2, for example. If the number of frames differs, the size of the recorded image must also be changed, and even if you finish shooting with the arrangement shown in Figure 1 and realize that you should have used the arrangement shown in Figure 2, you cannot change it. The shooting had to be done again.

Further, in FIG. 2, when the photographing of images F1, F2, and F3 is interrupted and the photographing is restarted next time, the image F1.
There was a drawback that it was impossible to tell what was recorded in F2 and F3. Furthermore, multiple images can be simultaneously
If the image is displayed on the RT and photographed, the above-mentioned drawbacks will be solved, but the number of pixels on the CRT screen will be insufficient and the quality of the recorded image will deteriorate.

An object of the present invention is to provide an image recording apparatus that eliminates the drawbacks of these conventional apparatuses, compresses stored image data, and displays the image arrangement to be recorded on a display means. is equipped with a multiple image storage unit that stores a plurality of image data, reads out the multiple image data stored in the multiple image storage unit, and records the multiple images on one hard copy. The recording apparatus is characterized in that it is provided with means for extracting pixels of the image data stored and arranged in the plurality of image storage section, and display means for displaying a composite image compressed by the extraction means.

The present invention will be explained in detail based on the embodiment shown in FIG. 3 and below.

FIG. 3 is a block diagram of the present invention, and is an embodiment in which an analog image signal is digitized, stored in a digital memory, and then converted into an analog signal again and recorded on a film with a laser beam. Analog image signal V is sent to A/D via amplifier 1.
digitized by converter 2 and stored in multiple image storage unit 3
is memorized. FIG. 4 shows the memory configuration of this multiple image storage unit 3. In this case, based on the example of FIG.
)~(M,N), image F2 is (N+1.1)~ of G2
(2M, N), image F3 is (1, N+1) to (M
, 2N), image F4 is (N+1.N+1) to (2
M, 2N) address numbers are stored respectively. For this purpose, the X address counter 4 and the Y address counter 5 are controlled by a clock pulse generator 6, a multiplexer 7, a frame counter 8, and a controller 9. When writing an image, the output C1 of the clock pulse generator 6 is controlled by the controller 9. is selected by multiplexer 7 under the control of . The X address counter 4 and the Y address counter 5 output 1 to M and 1 to N, respectively, when writing the image F1.
As shown in FIG. 4, the data of the image F1 is written in the storage area Gl. When writing image F2, X address counter 4
is controlled by the frame counter 8, and the Y address counter 5 outputs 1-N and writes the image F2 in the area G2. That is, the X address counter 4 and the Y address counter 5 are controlled by the frame counter 8. This can be realized by using a preset counter, and the images F3 and F4 can be similarly written to the castles G3 and G4, respectively.

The controller 9 is controlled by a selection means (not shown).
When displaying only a frame on a display device, pixels at the same addresses as those at the time of writing are read out from the multiple image storage unit 3 and sent to the CRT 12 via the D/A converter 10 and amplifier 11.
display on a display device such as That is, frame counter 8
1 frame of the desired image by setting the frame number to .

can be displayed.

When displaying a plurality of images on the CRT 12, a clock signal C2 faster than the output CI of the clock pulse generator 6 is selected by the multiplexer 7 under the control of the controller 9, and drives the X address counter 4 and the Y address counter 5. When the outputs of X address counter 4 and X address counter 5 are disabled by one bit, the lowest digit of the output of counter 4.5 is set to 0 or 1, and the addresses become only even or odd numbers, and the multiple image storage unit Addresses No. 3 are extracted one by one, and images old to H4 shown in FIG. 5 are displayed on the CRT 12. In other words, since the CRT 12 has a small number of pixels,
As can be seen from FIG. 5, a composite image with a pixel density of 1/4 is displayed, in which pixels are thinned out one by one in the X and Y directions. In this case, the X address counter 4 and the X address counter 5 operate as a 2M-ary counter and a 2N-ary counter, respectively.

In this way, when recording is performed after the image arrangement has been confirmed by the display image of the CRT 12, the clock signal C synchronized with the recording device by the output of the clock pulse generator 6 is used.
3 is selected by the controller 9 and multiplexer 7, and the X address counter 4 and X address counter 5 are (
1,1)~(2yr,i), (1,2)~(2M
, 2), .Contest- , Output addresses in the order of (1, 2N) to (2M, 2N) and read the image data in the multiple image storage section 3. The output of the multiple image storage unit 3 is passed through a D/A converter 10 and an amplifier 13 to form a time-series composite image signal, which drives an acousto-optic element 14. The output light of the laser oscillator 15 is deflected by a mirror 16 and then sent to the acousto-optic element 14.
The brightness is modulated by , and the silver halide film 18 is linearly scanned via the rotating polygon mirror 17 . The film 18 is moved by a sub-scanning system (not shown) in a direction perpendicular to the linear scanning by the rotating polygon mirror 17, and images J1 to J4 corresponding to FIG. 1 are recorded on the film 18.

In this embodiment, the display device is a CRT, and the recording device is a laser beam recording device, but the present invention is not limited to these. For example, the display device can be a liquid crystal display or a plasma display, and the recording device can be a flat CRT, It can also be used as an optical element array. Furthermore, it is effective as a recording medium for electrophotography in addition to silver halide film, and there is no problem even if the input image signal is a digital signal via a suitable interface.

Figures 6 and 7 are images F1 to F6 of the 6 frames in Figure 2.
FIG. 6 corresponds to FIG. 4, and FIG. 7 corresponds to FIG. 5. In FIG. 3, the multiple image storage unit 3 stores data for 6 frames, that is, 2M-
Assuming that the CRT 12 has a storage capacity of 3N, displaying one frame or four frames on the CRT 12 may be performed in the same manner as in the above example.

Also, when displaying 6 frames on CRT12,
The output of the address counter 4 is the same as in the previous embodiment, and 1/3 is applied to the X address counter 5 under the control of the controller 9.
If a dividing period is provided, it is possible to extract every three pixels in the Y direction, and an image consisting of pixels as shown in FIG.
2. In the example displayed in this manner, the aspect ratio of each image has changed from the original image, but for the purpose of checking the image arrangement, this change does not pose a major problem. Also, in Figure 7, N is shown as a multiple of 3, but N
There is no problem no matter what the number is, and in this case, the only difference in display is that the number of pixels in the vertical direction of one frame of image may be different.

As explained above, according to the image recording device according to the present invention, by combining images from multiple sides and displaying them on a CRT, defects such as recording unnecessary images or erroneous image arrangement can be avoided. This makes it easy to see what kind of image will be recorded on a single hard copy.
