Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image recording apparatus that records a plurality of images on one hard copy and allows the recorded contents to be confirmed in advance.

Conventional multi-format cameras are so-called CRT imaging devices, and when recording multiple images, the image arrangement is programmed, and each image is divided into one image according to the program.
The images are output one by one to a CRT, and projected and recorded onto a film using a lens optical system. Therefore, for example, once one image is recorded, it is impossible to change it.

Furthermore, there are many inconveniences in use, such as the image arrangement cannot be changed even if it is necessary during the process, and it is not possible to know what kind of images have been recorded until after the hard copy is completed. be.

Fig. 1 shows an example in which four frames of images FINF4 are arranged on a hard copy made of, for example, photographic film.In the conventional device, the image FINF4 is first output to a CRT and photographed, and then the image F2 is transferred to the same CRT. Four frames of images F1 to F, 4 are sequentially recorded by outputting them to and photographing them. 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, would have to be redone and the hard copy would be wasted.

Further, in a multi-format camera, not only the image arrangement shown in FIG. 1 but also six frames of images F1 to F6 can be arranged as shown in FIG. 2, for example. However, if the number of frames differs, the size of the recorded image will naturally change, and when I finished capturing the 1/@l image with the arrangement shown in Figure 1, I realized that I should have used the arrangement shown in Figure 2. However, changes cannot be made and the shooting will have to be restarted.Also, in Figure 2, if the shooting is interrupted when images F1, F2, and F3 are taken, then what will happen to images Fl-F3 when the shooting is resumed? The disadvantage is that it is not clear whether the information is being recorded or not. If multiple images are simultaneously displayed on the same CRT and taken, the above problem will be resolved, but the number of pixels on the CRT will be insufficient and the quality of the recorded images will deteriorate. .

The object of the present invention is to eliminate these drawbacks of the conventional apparatus, to provide an image storage section, to display images according to the image arrangement to be recorded, and to make it possible to change the image arrangement in the image storage section. The object of the present invention is to provide an image recording device that can perform failure-free recording and accurately grasp the state of images recorded on hard copies. , in an image recording device that reads image data from the multiple image storage section and records the plurality of images on one hard copy, changing the image arrangement of the plurality of image data stored in the multiple image storage section. and an image display means for confirming the changed image arrangement.

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

FIG. 3 shows one embodiment of the present invention, in which an analog image signal is digitized, stored in a digital memory, and then converted back into analog for laser beam recording. The analog image signal (2) is digitized by the A/D converter 2 via the amplifier 1 and stored in the multiple image storage section 3. FIG. 4 shows the memory configuration of the multiple image storage unit 3. The example shown in FIG. 4 is based on the image arrangement shown in FIG. 1, and the images Fl are (1,1) to (M,N ), image F2 is G2
(N+1,1) to (2M,N) of G3, image F3 is (N+1,1) to (2M,N) of G3
1, N+1) to (M, 2N), image F4 is (ll
They are stored at addresses I+l, N+1) to (2M, 2N), respectively. For this purpose, the X address counter 4 and the X address counter 5 are connected to a clock pulse generator 6, a multiplexer 7, a frame counter 8,
It is controlled by a controller 9 such as a microcomputer, for example, and when writing image data, the clock pulse output CI from the clock pulse generator 6 is selected by the multiplexer 7 under the control of the controller 9.

X address counter 4. X address counter 5 is image F
When writing 1, 1-M and 1 to N are output respectively, and the fourth
As shown in the figure, when writing the zero image F2 in which the image data of the image F1 is written in the area G1, the X address counter 4 is controlled by the frame counter 8, and the X address counter 4 is controlled by the frame counter 8.
, the X address counter 5 outputs 1 to N and writes the image data of the image F2 in the area G2. That is, this can be realized by using the X address counter 4 and the X address counter 5 as preset counters controlled by the frame counter 8, and the image data of the images F3 and F4 can be similarly written to the areas G3 and G4.

When displaying a plurality of image arrays stored in the plurality of image storage section 3, the output C is used as the output of the clock pulse generator 6.
The clock output C2 faster than I is sent to controller 9. selected by multiplexer 7, X address counter 4,
Assuming that the X address counter 5 is a 2M base counter and a 2N base counter, respectively, (1, 1) ~ (2M, 1), (1, 2) ~ (
2M, 2), 〇Φ, (1,2N) ~ (2) 1.2N
) and read out the image data in the multiple image storage section 3.
The output of the multiple image storage section 3 is sent to the D/A controller 10. The image is displayed on a display device such as a CRT 12 via an amplifier 11. Images F1 to H4 corresponding to images F1 to F4 in FIG. 1 are displayed on the CRT 12. However, in this case, CRT
12 requires the ability to display 2M02N pixels.

When changing the image arrangement here, for example, when replacing the image device 83 in the CRT 12, it is sufficient to replace the image data of areas Gl and 03 in the multiple image storage section 3. That is, (1.1) to (M, N) in FIG.
This means that the image data of (1, N+1) to (M, 2N) are exchanged. To do this, first set the controller 9 to image exchange mode, select the high-speed clock output C4 as the output of the clock pulse generator 6, and send it to the controller 9 and multiplexer 7. and address counter 1 that accesses buffer line memory 13 and 14.
Drive 5.

First, the frame counter 8 is set to frame number 1, and one line of the area Gl of the multiple image storage section 3 is read out and stored in the line memory 13. That is, the multiple image storage unit 3
The pixels at addresses (1,1) to (M,1) are stored in the line memory 13. Next, the frame counter 8 is set to frame number 3, and
The lines are read out and stored in the line memory 14. That is, the addresses (1, N+1) to (M,
N+1) pixels are stored in the line memory 14. Third, the pixels stored in the line memory 13 are stored in the multiple image storage unit 3.
Write to addresses (1, N+1) to (M, N+1) of
Fourth, the frame counter 8 is set to frame number 1, and the pixels stored in the line memory 14 are written to addresses (1, 1) to (M, 1) of the multiple image storage section 3. One line of area Gl and 63 can be exchanged in one cycle of the process. However, the first and second processes, and the third and fourth processes may be reversed. By repeating this cycle N times, all the image data of regions G1 and G3 can be exchanged. Also, in this explanation, an example of exchanging one horizontal row of areas Gl and 03 was shown, but
You can replace each column vertically, or you can start from any column.

After the internal replacement of the multiple image storage unit 3 is completed,
In the same manner as before, the multiple image storage unit 3 is read out and the CRT 12
When displayed, the image device and F3 of the CRT 12 are exchanged, and images are displayed in the order of F3, F2, old, and H4.

After confirming the image arrangement in the multiple image storage section 3 in this way, the output of the clock pulse generator 6 is the clock output C3 synchronized with the recording device, which is selected by the controller 9 and the multiplexer 7, and the X address counter 4, Y address counter 5 is (1, 1) ~ (2%, l), (1
,2) ~(2L2), @--(1,2N) ~(2M,
2N), and the image data in the multiple image storage section 3 is read out. The output of the multiple image storage unit 3 drives an acousto-optic element (A10 element) 17 via a D,/A converter lO and an amplifier 16. The output light of the laser oscillator 18 is reflected by the mirror 19, brightness-modulated by the acousto-optic element 17, and linearly scanned on the silver halide film 21 by the rotating polygon mirror 20. The silver halide film 21 is moved by a sub-scanning system (not shown) in a direction perpendicular to the linear scanning by the rotating polygon mirror 20, and images Jl corresponding to images F1 to F4 in FIG.
-J4 is recorded, but as described above, in the multiple image storage unit 3, area G1. ! : Since the image data with G3 is exchanged, images are recorded on the silver halide film 21 in the same order as displayed on the CRT 12: F3, F2, Fl, and F4.

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 is a liquid crystal display, a plasma display, and the recording device is a flat CRT, an optical It can also be effectively used for element arrays.

Moreover, as a storage medium, electrophotography other than the silver halide film 21 is also effective. Furthermore, the invention is applicable to digital image signals via a suitable interface. In the embodiment, a line memory is used, but the back memories 13.14 can be used as one pixel memory and the regions G1 and G3 can be exchanged one pixel at a time.
Of course, it is also possible to use an image memory for one frame.

5, 6, and 7 show other embodiments in which image arrays are changed by address inspection without moving image data within the multiple image storage unit 3 as in the previous embodiment. Changes are made. That is, in the embodiment of FIG.
3.14, it requires hardware such as address counter 15, and there are some drawbacks such as the long time it takes to exchange image data between Bondjo Gl and 03, but 85
The embodiments shown in FIGS. 7 to 7 are intended to solve these deficiencies.

First, the addresses of the multiple image storage unit 3 in FIG. 3 are not all consecutive addresses as shown in FIG.
As shown in FIG. 5, the frame number and the pixel number in each image are used as independent addresses, and addresses are assigned to all pixels of the plurality of images Fl-F4.

This embodiment can be realized by partially modifying the embodiment shown in FIG. 3, so only the modified portions will be explained with reference to FIG. 86. First, in this embodiment, the memory configuration of the multiple image storage section 3 is as shown in FIG. S5, and the line memory 13.
14. Delete the address counter 15 as it is not needed.0W In the diagram 46, the A/D converter 2, multiple image storage unit 3, X address counter 4, Y address counter 5, frame counter 8, and controller 9 are the same as in Figure 3. shall be. However, the X address counter 4 and the Y address counter 5 are simply M-ary and N-ary counters that are not controlled by the frame counter 8. Frame counter 8
The frame number output from the rewritable memory 2
2, and specifies the address of the multiple image storage unit 3. That is, the output of memory 22 is the first digit of the address shown in FIG. The output of frame counter 8 is memory 2
2 is specified, and the memory 22 outputs the contents of that address. The memory 22 functions as a lookup table and is rewritten by the controller 9. FIG. 7 shows the addresses and contents of this memory 22.

First, when input image signal (2) is written into the multiple image storage section 3, it is written into the memory 22 in the state shown in FIG. 7(a). In this case, the output of the frame counter 8 and the output of the memory 22 correspond, such that when the frame counter 8 outputs 1, the memory 22 outputs 1, and the images F1 to F4 are stored in the area G1-04 of the multiple image storage section 3. image data is written. When reading and displaying the multiple image storage unit 3, the output of the frame counter 8 is initially 1, and when the X address counter 4 advances M, it switches to 2, and when the X address counter 4 advances M again, it switches to 1, and so on. , 1 and 2 are repeatedly output N times each time the X address counter 4 advances to M bases, and when the Y address counter 5 advances to N times, 3 and 4 are output in the same way every time the X address counter 4 advances to M bases. and N
Output repeatedly. This is the carry signal XC for each M base of the X address counter 4, and the N signal of the Y address counter 5.
This can be realized by controlling the frame counter 8 using the carry signal YC for each digit.

In this way, the address of the multiple image storage unit 3 becomes (1
,1,1)~(1,)1.1),(2,1,1)~
(2,>1.1), (1,1,2)~(1,M,2)
, (2,1,2)~(2,M,2), φ−−(

) to (4, M, N) are read out in the order, and the images are displayed on the CRT 12 in the order of old, H2, H3, and H4, similar to the example in FIG.

Here, when exchanging the arrangement of images Fl and H3, the contents of addresses 1 and 3 of the memory 22 are exchanged as shown in FIG. 7(b). In this case, when frame counter 8 outputs 1, memory 22 outputs 3, when frame counter 8 outputs 2, it outputs 2, when frame counter 8 outputs 3, it outputs 1, and when frame counter 8 outputs 4, it outputs 4. output and store the memory 22 in FIG. 7(b)
). When this multiple image array is displayed on the CRT 12, the address of the multiple image storage section 3 is (3, 1
,1) ~(3,M,1), (2,1,1,)~
(2,M,1) , (3,1,2) ~(3,M,

4,1,N) to (4,M,N) are read out in the order of CRT
12, images are displayed in the order of H3, H2, old, and H4 as in the example of FIG.

In this way, when recording on a hard copy after confirming the image arrangement, the clock pulse signal is set to 03 as in the example shown in FIG. The addresses are read out in the same order as when they are displayed, and an image array J3, J2, jl, J4 similar to that displayed on the CRT 12 is recorded on the silver halide film 21.

Furthermore, after exchanging images Fl and H3, when exchanging images F1 and H4 on the CRT 12, that is, images H3 and H4, if the contents of addresses 1 and 4 in Fig. 87(b) are exchanged, the memory The contents of 22 are shown in figure w47 (c
), the CRT12 has H4, H2, old,
The image array is displayed in the order of H3.

Incidentally, it goes without saying that such re-exchange is similarly possible in the case of the embodiment shown in FIG.
If you remember the process of replacing the contents of the memory 22,
You can also return to the original image arrangement.

Furthermore, the present invention is not limited to the number of multiple images, and the memory capacity of the multiple image storage section 3 in the embodiment shown in FIG. For example, it is possible to handle a larger number of images. Furthermore,
Increase the image array from Figure 1 to Figure 2,
Conversely, it is also possible to reduce it. This is the third
By changing the rotational speed of the rotating polygon mirror 20 shown in the figure and the moving speed of the silver halide film 21, the size of the recorded image can be changed.

In this embodiment, the display device was a CRT, and the recording device was a laser beam recording method, but the present invention is not limited to these.
For example, display devices include liquid crystal displays, plasma displays,
As a recording device, it is also effective for flat CRTs, optical element arrays, etc. Furthermore, not only silver halide film but also electrophotography can be used as a recording medium. Furthermore, the present invention can also be applied to digital image signals via an appropriate interface.

As explained above, according to the image recording device according to the present invention, by displaying a plurality of images on a display device and easily changing the image arrangement, it is possible to record a wrong image arrangement on a hard copy. You can prevent it from being put away. Further, there is an advantage that it is obvious at a glance what kind of image will be recorded on one hard copy.
