In the absolute position data detection block 55, as shown in FIG. 6, the optical sensor 29 that optically detects the mark 27 recorded on the recorded recording medium 38 and sends the signal to the main controller 2. Is provided. The optical sensor 29 is arranged at the same position as the optical head 26 at the positions of both the path length adjusting mechanisms 17 and 18. The image pickup / playback unit 1 is provided with a display unit (not shown) which is composed of an LCD and performs a display operation according to an instruction from the main controller 2.

In the present embodiment having the above-described 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.

Then, 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 sent in the storage roll direction. Then, the pinch roller 15,
The actuator operates simultaneously with the start of rotation of 16 and the storage roll 7, and the movable roller 17c of the first path length adjusting mechanism 17 moves backward away from the photosensitive recording medium 8 as shown in FIG. 8B. Direction, the movable roller 18c of the second path length adjusting mechanism 18 simultaneously moves 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. 8B and 8C 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 ...

Further, the absolute position data generation circuit 28, for example, in the configuration of (1) described above, cumulatively calculates the actual use time from the start of imaging by the built-in time counter. Also, as mentioned above, the pitch p of the frame arrangement is 10 m.
Since m is the image pickup rate = 30 frames / sec, the recorded distance from the recording start position of the photosensitive recording medium 8 to the present time can be obtained by using these values, and this distance is shown. Output data sequentially. According to this data, the optical head 26 operates at a constant time interval or continuously, so that the mark 27 including the recorded distance as absolute value data is continuously or intermittently formed on the photosensitive recording medium. It is exposed to 8.

The photosensitive recording medium 8 used in this embodiment has an effective length of 270 m as described above, and the maximum image pickup time is 15 minutes. Therefore, the main controller 2
Is the used amount of the photosensitive recording medium 8, the remaining amount of the photosensitive recording medium 8, based on the absolute position data and these known data.
Relative data such as the distance to the end of the photosensitive recording medium 8 and the remaining recordable time are calculated and displayed on the display unit.

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 still image of the subject image in each frame 19 and the photosensitive recording medium 8 on which the mark 27 is exposed. Therefore, the R, G, B photosensitive layers 1 of the photosensitive recording medium 8
The developing and fixing solution permeates 2 to 14, and the photosensitive layers 12 to 14 have different wavelengths λ depending on R, G, and B of the subject image.
It develops an absorption spectrum having peaks at 1, λ2, and λ3. The latent image of the mark 27 is also made into a real image by the developing and fixing solution.

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 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.

In this way, the imaged image projected by the surface imaging optical system 9 is directly recorded on the photosensitive recording medium 8 without intervening processing such as conversion into electric signals. 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.

Further, the sensor driver 40 has a timing designated by the main controller 2, that is, the light source 36.
The color area sensor 39 is driven at a timing of 1/30 second for turning on, and the electric charges generated as a result of photoelectric conversion of the color area sensor 39 are transferred to the preprocessing circuit 41 at the timing. This transfer output signal is subjected to removal of the reset pulse and adjustment of the signal level by the preprocessing circuit 41, and then by the low-pass filter 42.
The color signal component is removed to generate a luminance signal Y, and the luminance signal Y is corrected by the luminance signal processing circuit 43 and input to the color encoder 46.

On the other hand, the transfer output signal from the color area sensor 39 transferred from the pre-processing 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.
It is also possible to print out each still image with a video printer.

When the recorded recording medium 38 runs during reproduction, the optical sensor 29 detects the mark 27 that arrives in front of the optical sensor 29 accordingly.
Then, the main controller 2 executes the same calculation as described above based on the absolute position data indicated by the mark 27, and the reproduction amount of the recorded recording medium 38 from the reproduction start position, the remaining amount of the recorded recording medium 38, The end time of the recorded recording medium 38, the elapsed time from the reproduction start position, and the remaining reproducible time are calculated and sent to the main controller 2. Then, the main controller 2 displays these calculation results, and when the remaining amount becomes “0”, the image data conversion block 3
3, the operation of the medium transport block 4, and the data conversion block 35 are all stopped to stop the reproduction.

That is, by using the 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, a key for inputting absolute position data may be provided in the reproducing unit so as to start the reproduction from the position of the absolute position data designated by this key. Further, in this embodiment, the mark 27 is exposed on the upper part of the photosensitive recording medium 8.

It has the property of causing a change in absorbance in the spectrum. The photosensitive recording medium 8 has a thickness t of 10 μm,
The width w shown in FIG. 3D is 25 mm and the effective length is 270 m. Therefore, when the core diameter of the supply roll 6 is 10 mm, the winding diameter is 60 mm at maximum.

As shown in FIG. 26, the color separation optical system 311 has an optical axis direction and a direction orthogonal thereto on the optical axis of the surface imaging optical system 9 which is incident through the shutter 10. The first half mirror 111 is arranged at an angle at which light can be separated.

Further, the first to third prisms 113 to 11
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. 27, 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, as shown in FIG. 28, the captured image formed by the surface imaging optical system 9 is subjected to the R optical image 19R, G optical image 19G, B for each component by the filters 11R, 11G, 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 on which 9R, 19G, and 19B are projected are shown in FIG.
As shown in (D), horizontal (a) x vertical (b) = 9 x 16 m
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. Note that FIG. 24 and FIG.
As shown in FIG. 9, the configurations of the medium carrying block 4 and the absolute position data recording block 25 are the same as those in the first embodiment.

In 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. 30 (A), the optical shutter 10 opens according to the instruction from the main controller 2 at the timing when the intermittent movement unit 8a is stationary, and the optical shutter 10 opens as shown in FIG. 30 (B). By moving the intermittent moving unit 8a at the timing when 10 is closed, 1/3 of the captured image is obtained.

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 described above, 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 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.

Further, as described above, the picked-up image formed on the photosensitive recording medium 8 by the surface image-forming optical system 9 and projected through the color separation optical system 311 is converted into an electric signal. Since the image is directly recorded without interposing the optical image, the optical images 19R, 19G, 1 recorded on each frame 19 are recorded.
It is possible to secure the fidelity of the still image including 9B 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.

Further, the configuration including the optical sensor 56 in the absolute position data detection block 55 and the transport mechanism for the recorded recording medium 93 are the same as those of the reproducing unit 31 of the above-described embodiment. As described above, even in the device using the monochrome photosensitive recording medium 83, by providing the optical head 26 and the optical sensor 56, it is possible to record the mark 27 at the time of image pickup and detect the mark 27 at the time of reproduction as described above. It will be possible.

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.
