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 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. 9B. 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 above operation shown in FIGS.
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. 10A, the optical shutter 10 opens according to the instruction from the main controller 2 at the timing when the intermittent moving unit 8a is stopped, and the optical shutter 10 opens.
As shown in FIG. 6, by moving the intermittent moving unit 8a at the timing when the optical shutter 10 is closed, it is possible to sequentially expose the frames 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 different wavelengths λ1, λ2, and λ3, respectively, is developed, and the sound of the surrounding environment during this imaging is detected by the microphone 73 and converted into an electric signal. The electric signal from the microphone 73 is frequency-modulated by the FM modulation circuit 742, and after the direct current bias is added by the direct current bias adding circuit 743, the optical recording head 75 irradiates and records the constant speed portion of the photosensitive recording medium 8. It By the recording spot of the optical recording head 75, an audio track 79 having frequency-modulated information is photosensitized on the photosensitive recording medium 8, and the photosensitized audio track 79 is formed.
Is a static image recorded on each frame 19
The developing and fixing unit 20 simultaneously performs the developing and fixing process. Therefore, at the time when the image capturing is completed, it is possible to obtain the recorded recording medium 38 in which not only the still image exposed on each frame 19 but also the audio track 79 is made into a real image.

At this time, as shown in FIG. 11, 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 solution is applied to the photosensitive recording medium 8 in a uniform amount over the entire length, whereby each frame 19
Also, the effect of developing and fixing the audio track 79 can be made uniform.

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)). Then, when the reproduction is started after the rewinding, the pinch rollers 15 and 16 and the storage roll 7 first are the same as those at the time of imaging described with reference to FIGS. 9A, 9B and 9C.
Also, the second path length adjusting mechanisms 17, 18 and the like operate. 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.

At this time, the sensor driver 40 determines the timing designated by the main controller 2, that is, the light source 3.
The color area sensor 39 is driven at a timing of 1/30 seconds for lighting 6 and the electric charge generated as a result of photoelectric conversion of the color area sensor 39 is transferred 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.

Further, 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.

On the other hand, when the reproduction is started, the light source 83 is turned on at the same time as the reproduction is started, and the light generated thereby is applied to the audio track 79. Therefore, the recording signal of the audio track 79 is imaged on the photoelectric conversion sensor 85 via the imaging optical system 84. Then, each photoelectric conversion sensor 85
Performs photoelectric conversion that reflects the recording state of the audio track 79 to generate charges, and outputs the generated charges as an electric signal. This electric signal is the bias removal circuit 861.
After the DC bias is removed by, the audio signal is demodulated by the FM demodulation circuit 862 and output.

Therefore, the color encoder 46 described above is used.
The video signal output from the FM demodulation circuit 862
By operating the television passive device based on the audio signal output from the device, it is possible to listen to the ambient sound at the time of imaging while visually recognizing a color moving image made up of a series of still images recorded in each frame 19. That is, by using the image pickup / reproduction device 61, as shown in FIG.
All of "1. shooting" → "2. automatic development" → "3. replay" can be performed. As a result, the moving image f of the captured image F and the ambient sound 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, and the like, which can be performed quickly and smoothly. Becomes

However, the image pickup unit which has completed the image pickup with the units 1 and 31 as separate bodies. The entire unit 1 may be housed in the playback unit 31, or both units 1 and 31 may be separate imaging devices and image playback devices.

FIG. 13 shows another example of the configuration of the data conversion block 35. That is, the point that the sensor driver 40 and the preprocessing circuit 41 are provided is the same as the configuration described with reference to FIG. 7. 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.

FIG. 22 shows another construction of the image pickup unit 1. That is, in the image recording block 3 of the image pickup unit 1, a monochrome photosensitive recording medium 8 wound around the supply roll 6 and wound around the storage roll 7, and a surface imaging optical system 9 for forming an image to be picked up. An optical shutter 10 and a color separation optical system 311 arranged on the optical axis of the surface imaging optical system 9 are provided. As shown in FIG. 23A, the photosensitive recording medium 8 is formed by laminating a Vis whole area photosensitive layer 313 on a base 11 made of a thin film transparent resin. The Vis whole-area photosensitive layer 313 is exposed to the entire spectrum of visible light as shown in FIG. 7B, and is subjected to a development process so as to center on a specific wavelength λ1 as shown in FIG. 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, a width w shown in FIG. 3D of 25 mm, and an effective length of 270 m. Therefore, when the core diameter of the supply roll 6 is 10 mm. The maximum winding diameter is 60 mm.

As shown in FIG. 24, the color separation optical system 311 has the optical axis direction and the 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. A second half mirror 112 is arranged on the side of the first half mirror 111 at the same angle as the first half mirror 111, and the light transmitted through the second half mirror 112 is
A first prism 113 that polarizes in a direction parallel to the optical axis of the surface imaging optical system 9 is arranged. Further, in front of the first half mirror 111, the second prism 1 for polarizing the light transmitted through the first half mirror 111 in a direction orthogonal to the second prism 1 is provided.
14 are arranged.

On one side of the second prism 114 and in front of the second half mirror 112, a full mirror 116 for reflecting the light from the second half mirror 112 to the second prism 114 is arranged. This full mirror 116
The light reflected by is polarized by the second prism 114 in a direction parallel to the optical axis of the surface imaging optical system 9. The third prism 115 is provided on the other side of the second prism 114.
The third prism 115 polarizes the light reflected by the second prism 114 in a direction parallel to the optical axis of the surface imaging optical system 9.

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. 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.
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. Further, in this image pickup unit, the configurations of the medium carrying block 4, the medium developing block 5, and the voice recording block 72 are the same as those in the above-described embodiment, as shown in FIG.

With the above configuration, when image pickup is started,
By repeating the above-described operation shown in FIGS. 9B and 9C at intervals of 1/30 second, the photosensitive recording medium 8 becomes the supply roll 6
While being pulled out at a constant speed and wound around the storage roll 7 at the same speed, the intermittent moving portion 8a is stationary between the fixed rollers 73b and 18a at intervals of 1/30 seconds. Therefore, as shown in FIG. 28 (A), the optical shutter 10 opens according to the instruction from the main controller 2 at the timing when the intermittent movement unit 8a comes to rest, and 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.
It is possible to sequentially expose the frames 19 ... With the R optical image 19R, the G optical image 19G, and the B optical image 19B for each R, G, and B component, which are still images every 0 seconds.

On the other hand, in the developing / fixing unit 20, the lid of the tank 21 is driven to open in response 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 described above, the developing / fixing unit 20 applies the developing / fixing liquid 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, whereby the developing / fixing effect of each frame 19 and the voice recording track 79 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, each frame 19 of the photosensitive recording medium 8 on which the still image is exposed and the audio track 79 are sequentially developed and fixed by the developing and fixing unit 20, so that the image and the audio can be reproduced at the same time when the image pickup is completed. It is possible to obtain various recording media.

FIG. 29 shows another configuration of the color separation optical system 311. That is, the first dichroic mirror surface 326 that transmits B light and reflects R light and G light in a direction orthogonal to the optical axis on the optical axis of the surface imaging optical system 9 that is incident through the shutter 10. Is provided. A first total reflection mirror surface 327 that reflects all incident light in a direction parallel to the optical axis is provided on the side of the first dichroic mirror surface 326, and in front of the first total reflection mirror surface 327.

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.
