The optical sensor 56 is arranged at a position where the label 27 recorded by the image pickup unit 1 can be detected in the intermittent moving portion 38a, and the detection signal is input to the main controller 32.

In the present embodiment having the above-mentioned structure, when the image pickup is started, the photosensitive recording medium 8 in the non-image pickup state is set.
Are set as shown in FIG. At this time, both movable rollers 17c and 18c are stopped at the same neutral position N, which is respectively retracted from the fixed rollers 17a, 17b, 18a and 18b by a predetermined distance, as shown in FIG.

When the image pickup is started, the motor is started in accordance with the instruction from the main controller 2,
The pinch rollers 15 and 16 and the storage roll 7 start rotating at the same linear velocity, whereby the photosensitive recording medium 8 is fed in the forward direction F. Then, the pinch rollers 15 and 16
The actuator operates at the same time as the rotation of the storage roll 7 starts, and the movable roller 17c of the first path length adjusting mechanism 17 moves in the backward direction away from the photosensitive recording medium 8 as shown in FIG. 8B. In the movable roller 18c of the second path length adjusting mechanism 18, the movable rollers 18c simultaneously move in the forward direction toward the photosensitive recording medium 8 by the equal distance L1 from the neutral position N.

Therefore, during that time, the photosensitive recording medium 8 pulled out from the supply roll 6 with the rotation of one of the pinch rollers 15 has its path length lengthened by the backward movement of the movable roller 17b, and the pulled-out amount is absorbed. To be done. Further, when the movable roller 18c moves forward, the path length of the photosensitive recording medium 8 is shortened on the side of the second path length adjustment mechanism 18, and the surplus generated by this is accompanied by the rotation of the pinch roller 16 and the storage roll 7. And is wound up on the storage roll 7. Therefore, during this period, the intermittent movement portion 8a of the photosensitive recording medium 8 is stopped without moving.

Then, in this way, the pinch rollers 15, 1
6 and the storage roll 7 continue to rotate at the same linear velocity, when 1/30 second elapses, the actuator operates in the opposite direction to the above, and as shown in FIG. The movable roller 17c of the first path length adjusting mechanism 17 moves forward in the direction approaching the photosensitive recording medium 8, and the movable roller 18c of the second path length adjusting mechanism 18 moves backward from the photosensitive recording medium 8. In the same direction, the same distance L2 is simultaneously moved.

Therefore, the path length of the photosensitive recording medium 8 is shortened on the side of the first path length adjusting mechanism 17, and at the same time, the path length of the photosensitive recording medium 8 is increased on the side of the second path length adjusting mechanism 18. . For this reason, the surplus on the side of the first path length adjusting mechanism 17 caused by the shortening of the path length arrives at both of the adjacent fixed rollers 17b and 18a, and at the time of the same figure (B), between the fixed rollers 17b and 18a. The intermittent moving portion 8a interposed in the second path length adjusting mechanism 18
Absorbed by the side.

The operation shown in FIGS. 8 (B) and 8 (C) is 1
By repeating every 30 seconds, the photosensitive recording medium 8 is pulled out from the supply roll 6 at a constant speed and wound around the storage roll 7 at the same speed, while the intermittent moving portion 8a is sequentially moved to 1 /
At 30-second intervals, the stationary rollers 17b and 18a stand still. Therefore, as shown in FIG. 9 (A), the optical shutter 10 opens according to an instruction from the main controller 2 at the timing when the intermittent moving unit 8a is stationary, and as shown in FIG. 9 (B), the optical shutter 10 opens. By moving the intermittent moving unit 8a at the closing timing, the captured image 1
It is possible to sequentially expose still images every 30 seconds to each frame 19 ...

On the other hand, in the developing and fixing unit 20, the lid of the tank 21 is driven to open according to an instruction from the main controller 2 issued at the same time as the start of image pickup. As a result, the coating member impregnated with the developing and fixing solution is exposed to the outside of the tank 21 and comes into contact with the photosensitive recording medium 8 on which the still image of the subject image is exposed in each frame 19. Therefore, the developing / fixing solution permeates the R, G, and B photosensitive layers 12 to 14 of the photosensitive recording medium 8, and the photosensitive layers 12 to 14 cause R and G of the subject image to
Depending on G and B, an absorption spectrum having peaks at different wavelengths λ1, λ2, and λ3 is developed.

Further, when the user operates a predetermined switch at the time when the image pickup of the image to be retrieved is started, the optical head 2 is instructed by the main controller 2.
6 lights up momentarily. Then, the light from the optical head 26 is transmitted to the frame 1 located at the intermittent moving portion 8a at that time.
The lower part of the label 9 is illuminated, whereby the label 27 (FIG. 2) is sensitized. The photosensitive-recorded label 27 is also developed and fixed in the developing / fixing unit 20 together with the above-mentioned still images.

At this time, as shown in FIG. 10, the developing / fixing unit 20 applies the developing / fixing liquid to the photosensitive recording medium 8 at a constant speed moving portion moving at a constant speed (v). . Of course, when the imaging is stopped, the lid of the tank 21 is closed, so that the excessive development and fixing solution is not applied to the stopped photosensitive recording medium 8. Therefore, the developing / fixing liquid is applied to the photosensitive recording medium 8 in a uniform amount over the entire length thereof, whereby the developing / fixing effect of each frame 19 can be made uniform.

As described above, the image-captured image projected by the surface image-forming optical system 9 is directly recorded on the photosensitive recording medium 8 without intervening processing such as conversion into an electric signal. Therefore, it is possible to secure the fidelity of the still image recorded in each frame 19 to the captured image. Moreover, each frame 19 of the photosensitive recording medium 8 on which a still image is exposed is exposed.
Is sequentially developed and fixed by the developing / fixing unit 20, so that a reproducible recording medium can be obtained at the same time as the end of imaging.

Then, when the reproduction of the imaged result is started, the recorded recording medium 38 is rewound to the supply roll 6 side. This rewinding is performed by both path length adjustment records 17, 1.
8 both movable rollers 17c, 18c to the neutral position N (see FIG.
The operation is performed by rotating the supply roll 6 in the reverse direction while stopped at (A)).

After rewinding, when reproduction is started,
8A, 8B, and 8C, the pinch rollers 15 and 16, the storage roll 7 first and second path length adjusting mechanisms 17 and 18, and the like operate in the same manner as during imaging. As a result, the recorded recording medium 38 is pulled out from the supply roll 6 at a constant speed and is wound around the storage roll 7 at the same speed, while the intermittent moving portion 38a is at 1/30 second intervals and both fixed rollers 17b and 18a. Still in the meantime. Therefore, according to the instruction from the main controller 2, the light source 36 is turned on at the timing when the intermittent movement unit 38a is stationary, and the intermittent movement unit 8a is moved at the timing when the light source 36 is turned off, whereby each frame 19 of the captured image is moved. The still image recorded in .. is imaged on the color area sensor 39 by the imaging optical system 37 every 1/30 seconds.

On the other hand, the sensor driver 40 drives the color area sensor 39 at the timing instructed by the main controller 2, that is, every 1/30 second to turn on the light source 36, and photoelectric conversion of the color area sensor 39 is performed. The resulting charges are transferred and output to the preprocessing circuit 41 at the timing. The transfer output signal is subjected to the removal of the reset pulse and the adjustment of the signal level by the preprocessing circuit 41, and then the color signal component is removed by the low-pass filter 42 to generate the luminance signal Y. The luminance signal processing circuit 43 subjects the Y to the above-described gamma correction and the like, and inputs it to the color encoder 46.

On the other hand, the transfer output signal from the color area sensor 39 transferred from the preprocessing circuit 41 to the color signal separation circuit 44 is converted by the color signal separation circuit 44 into R, G, and
After being separated into signals of B color components only, the color signal processing circuit 45 performs white balance, gamma correction, and the like, and also converts them into color difference signals RY and BY. Then, when the color difference signals R-Y and B-Y and the luminance signal Y are input, the color encoder 46 generates and outputs a video signal according to the NTSC standard based on these. Therefore, based on this output video signal, the television passive unit operates, so that a color moving image can be visually recognized as a series of still images recorded in each frame 19.
Further, each still image can be printed out by the video printer.

When the supply roll 6 is rotated in the winding direction without operating both path length adjusting mechanisms 17 and 18, rewinding is performed, and when the storage roll 7 is rotated in the winding direction. Allows fast forward. When the optical sensor 56 detects the label 27 in the state of rewinding or fast-forwarding, the controller 32 instructs the motor to stop the driven roll 8.
As a result, it is possible to search for the part with the label 27. Further, when the signal from the optical sensor 56 is input, the main controller 32 starts reproduction in the same manner as described above, whereby the image from the searched portion can be visually recognized.

Therefore, by using this image pickup / reproduction device 61, as shown in FIG.
All of "2. Automatic development" → "3. Reproduction" can be performed. As a result, the moving image f of the captured image F can be reproduced on the television receiver 65, the still image f ′ of the captured image F can be printed by the video printer 66, etc., quickly and smoothly. In the above embodiments, the image pickup / reproduction device in which the image pickup unit 1 and the reproduction unit 31 are integrally assembled is shown. However, the image pickup unit 1 as a whole having the units 1 and 31 as a separate body is completed. May be housed in the playback unit 31, or both units 1 and 31 may be separate imaging devices and image playback devices. Further, in this embodiment, the label 27 is recorded in response to the switch operation by the user. However, the optical head 26 is automatically operated by the instruction from the main controller 2 at the time of starting each imaging. Alternatively, the label 27 may be recorded.

FIG. 12 shows an image pickup / reproduction device 101 according to the second embodiment of the present invention. The imaging / playback apparatus 101 includes a main controller 102, a label recording device 103 and a display device 106 controlled by the main controller 102, a label detection sensor 104 for inputting a label detection signal to the main controller 102, and a main controller 102. Key input unit 105 for inputting key operation information
It is composed of

Before image pickup, data such as image pickup date and time and label number are input in advance by operating the key input unit 105 or the operation of the main controller 102. Then, at the time of image capturing, the label recording device 103 is activated in response to a switch operation by the user or in response to an instruction from the main controller 10, and the data is photosensitive-recorded on the photosensitive recording medium together with the label.

During reproduction, the label detection sensor 10
4 detects the data recorded with the label and the main controller 102 causes the display device 106 to display this data. Further, if the user operates the key input unit 105 to specify the shooting date and time and the label number, and then rewinds or fast-forwards,
Based on this, the main controller 102 stops the photosensitive recording medium at the position of the matching shooting date and time and the label number. Therefore, according to this embodiment, it is possible to perform a more functional search and also to visually confirm the search result.

FIG. 13 shows another example of the configuration of the data conversion block 35. That is, FIG. 11 shows that the sensor driver 40 and the preprocessing circuit 41 are provided.
The configuration is the same as that described above. However, the transfer output signal from the color area sensor 39 processed by the preprocessing circuit 41 is digitized by the A / D converter 47. The digitized image data is stored in the memory 49 whose data input / output is controlled by the memory controller 48.

The operation matrix 50 is the memory 49.

The color encoder 46 is analogized by the D / A converter 51, and the color encoder 46 generates and outputs a video signal by the analogized luminance signal Y and color difference signals RY and BY.

As described above, in the present configuration, since the signal from the color area sensor 39 is digitized by the A / D converter 47 and the digitized image data is stored in the memory 49, the read speed is read by the memory controller 48. A variety of reproduction modes are possible by changing it.

In front of 6, an R light transmission filter 11R, a G light transmission filter 11G, and a B light transmission filter 11B are arranged. In the R light transmission filter 11R, as shown in FIG. 25, the upper limit wavelength is 430 to 480 μm.
As m, it has a characteristic of transmitting wavelengths from 380 μm to the upper limit wavelength. Further, in the G light transmission filter 11G, the lower limit wavelength is 430 to 480 μm, and 560 to 59
The characteristic is that the band between the upper limit wavelength and the lower limit wavelength is transmitted with 0 μm as the upper limit wavelength.
No. 19 has a characteristic that the lower limit wavelength is 560 to 590 μm and the band between this lower limit wavelength and 770 μm is transmitted. Therefore, the captured image formed by the surface imaging optical system 9 is, as shown in FIG. 26, the R optical image 19R, the G optical image 19G, and the B optical image 19G for each component by the filters 11R, 11G, and 11B, respectively. The image is decomposed into an optical image 19B and is projected on the frame 19 by an intermittent moving portion 8a of the photosensitive recording medium 8 described later. That is, one frame is formed by the recording areas of the R optical image 19R, the G optical image 19G, and the B optical image 19B obtained by dividing and projecting this one still image into R, G, and B.

In this embodiment, each optical image 1
9R, 19G, 19B are separated in the horizontal direction along the moving direction of the photosensitive recording medium 8, and each optical image 1
The areas where 9R, 19G, and 19B are projected are shown in FIG.

m, and the pitch p for arranging the tops 19 is 30 mm.
Further, in this embodiment, the imaging rate = 30 frames / sec according to the NTSC standard of 30 frames / sec.
In this embodiment, which has an effective length of 270 m, the imaging time is 5 minutes. Further, the optical shutter 10 opens at a frequency of 30 times / sec according to an instruction from the main controller 2, and the opening operation time at that time is 1/5.
It is about 0 to 1/1000 seconds. 22 and 2
As shown in FIG. 7, the configurations of the medium carrying block 4 and the label recording block 25 are similar to those of the first embodiment described above.

With the above structure, when image pickup is started,
By repeating the above-described operation shown in FIGS. 8B and 8C at intervals of 1/30 second, the photosensitive recording medium 8 is supplied to the supply roll 6
While being pulled out at a constant speed and being wound around the storage roll 7 at the same speed, the intermittent moving portion 8a sequentially stands still between the fixed rollers 17b and 18a at intervals of 1/30 seconds. Therefore, as shown in FIG. 27A, the optical shutter 10 opens according to the instruction from the main controller 2 at the timing when the intermittent movement unit 8a is stopped, and the optical shutter 10 opens as shown in FIG. By moving the intermittent moving unit 8a at the timing when 10 is closed, 1/3 of the captured image is obtained.

On the other hand, in the developing / fixing unit 20, the lid of the tank 21 is driven to open according to an instruction from the main controller 2 issued at the same time as the start of image pickup. As a result, the coating member impregnated with the developing and fixing solution is exposed to the outside of the tank 21 and comes into contact with the photosensitive recording medium 8 on which the still image of the subject image is exposed in each frame 19. Therefore, the developing and fixing solution permeates the Vis whole-area photosensitive layer 313 of the photosensitive recording medium 8, and the Vis whole-area photosensitive layer 313 develops an absorption spectrum having a peak at the wavelength λ1. At this time, as shown in FIG. 10, the developing / fixing unit 20 applies the developing / fixing solution to the photosensitive recording medium 8 at the constant speed moving portion moving at a constant speed (v). Of course,
When the image pickup is stopped, the lid of the tank 21 is closed, so that the excessive developing and fixing solution is not applied to the stopped photosensitive recording medium 8. Therefore, the developing / fixing liquid is applied to the photosensitive recording medium 8 in a uniform amount over the entire length thereof, whereby the developing / fixing effect of each frame 19 can be made uniform. Further, in this way, the imaged image formed on the photosensitive recording medium 8 by the surface imaging optical system 9 and projected via the color separation optical system 311 intervenes a process such as conversion into an electric signal. Since the image is directly recorded without being recorded, the optical image 19 recorded on each frame 19 is recorded.
It is possible to secure the fidelity of the still image composed of R, 19G, and 19B with respect to the captured image. Moreover, since each frame 19 of the photosensitive recording medium 8 on which the still image is exposed is sequentially developed and fixed by the developing and fixing unit 20, a reproducible recording medium can be obtained at the same time as the image pickup is completed.

On the other side of the second total reflection mirror surface 329, a third total reflection mirror surface 329 that reflects all incident light in a direction parallel to the optical axis is provided. A total reflection mirror surface 330 is provided. Therefore, according to this configuration, the imaged image from the surface imaging optical system 9 can be decomposed into R, G, and B light components without using a prism and only by the mirror, and the color separation optical system 311 can The structure can be simplified.
