Then, the image sensor converts the optically magnified image into an electric signal, and based on the electric signal, an image signal corresponding to a predetermined output device is similarly generated. That is, when the still image is enlarged and reproduced, since the original image itself is enlarged by the optical system, the image is not deteriorated when the original image is reproduced, and the high quality of the reproduced image is maintained.

Further, in the image pickup / reproduction device having the above-mentioned structure, the picked-up image projected by the image pickup optical system is stopped on the photosensitive recording medium conveyed by the first conveying means as the optical shutter operates. The images are sequentially recorded in different areas as an image. The photosensitive recording medium on which the still image is exposed is developed and fixed by the developing and fixing processing means.
At this point, a recorded recording medium that can be reproduced by the image reproducing device is obtained. The still image recorded on the recorded recording medium is read by the image sensor, and a reproduced image signal is generated in the same manner as the image reproducing device described above.

Is. The color encoder 46 receives the luminance signal Y from the luminance signal processing circuit 43 and the color signal processing circuit 4
A video signal is generated from the color difference signals R-Y and B-Y from 5 and output to an external television receiver or video printer.

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.

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. 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 in accordance with the rotation of the one pinch roller 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 adjusting 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. At this time, as shown in FIG. 10, the photosensitive recording medium 8 has a constant speed (v).
The developing / fixing unit 20 applies the developing / fixing liquid at the constant-velocity moving portion which is moving. 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 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 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)).

Then, when the reproduction is started after rewinding, if a magnification setting switch (not shown) is operated to set "equal magnification", the zoom-up optical system 37 and the color area sensor 39 are appropriately indicated by arrow A. It is driven in the ~ D direction to form a state in which the entire still image is projected in the frame 19 over the entire area of the color area sensor 39. When the reproduction is started in this state, the pinch rollers 15 and 16, the storage roll 7, the first and the second path length adjusting mechanisms 17 and 18, as in the case of imaging described with reference to FIGS. 8A, 8B, and 8C. Etc. works. 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. A still image recorded in .. is imaged on the color area sensor 39 by the zoom-up 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 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.
Further, each still image can be printed out by the video printer.

Further, in the case of enlarging and reproducing a part of the desired frame 19, after stopping the recorded recording medium 38 at the position, the magnification setting switch is operated to set an arbitrary magnification. Then, the drive mechanism operates according to an instruction from the main controller 2, and the zoom-up optical system 37 and the color area sensor 39 are driven in the directions A and B indicated by the arrows according to the set magnification. As a result, the focal length of the zoom-up optical system 37 is increased, and the distance between the recorded recording medium 38 and the zoom-up optical system 37 and the distance between the recorded recording medium 38 and the color area sensor 39 are correspondingly increased. Each increase to an appropriate value. As a result, the rectangular area S in the frame 19 is enlarged as shown in FIG.
The image is projected on the entire surface of the color area sensor 39.

When a position adjustment switch provided separately is subsequently operated, the zoom-up optical system 37 and the color area sensor 39 are driven in synchronization with the directions C and D of the arrow, and the movable rollers 17c, With the 18c stopped at the neutral position N, the supply roll 6 and the storage roll 7
When the and are rotated in the forward or reverse direction, the recorded recording medium 3
8 is driven in the arrow E direction. As a result, the rectangular area S moves to an arbitrary position in the frame 19 and the frame 1
It is possible to magnify an arbitrary area within 9 and project it on the color area sensor 39. The magnified image projected on the color area sensor 39 is photoelectrically converted in the same manner as described above, and the color encoder 46 generates and outputs a video signal in accordance with the NTSC standard based on this. Of course, if continuous reproduction is performed with this enlargement ratio set, a video signal capable of reproducing a partially enlarged continuous image is generated.

That is, by using this image pickup / reproduction device 61, as shown in FIG.
Performing “2. automatic development” → “3. Reproduction”, the moving image f of the captured image F can be visually recognized on the television receiver 65, or the still image can be printed out by the video printer 66. In "3. Playback", an arbitrary portion of an arbitrary frame can be magnified at an arbitrary magnification ratio so that it can be visually recognized by the television receiver 65 or can be printed out by the video printer 66. At this time, the image enlargement processing is performed by the zoom-up optical system 37 before the color area sensor 39 without being digitally processed after the color area sensor 39. A magnified image can be obtained.

In the above embodiments, the image pickup / playback apparatus in which the image pickup unit 1 and the playback unit 31 are integrally assembled is shown. However, the image pickup unit 1 and the unit 31 are separated and the image pickup is finished. The entire unit 1 may be housed in the reproduction unit 31, or both the units 1 and 31 may be separate image pickup devices and image reproduction devices.

FIG. 12 shows another configuration example 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.
Luminance data Y and color difference data R-Y and B-Y are calculated from the R, G, and B digital data output from, and at this time, calculations that also take into account gamma correction, contour correction, and white balance processing are performed. Run. The gamma and white balance correction here are performed by the gamma of the color area sensor 39,
Not only the white balance but also the recorded recording medium 3
8 exposure-development density characteristics, spatial frequency-development density characteristics,
The spectral characteristic is also corrected, and data corresponding to blanking is also added. Also, the calculation matrix 50
Luminance data Y, color difference data RY and BY from
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 this 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.

FIG. 13 is a block diagram showing the structure of an image pickup / playback apparatus 91 according to the third embodiment of the present invention. The image pickup / playback apparatus 91 is the same as the image pickup / playback apparatus described above as the first embodiment.

Has been done. As shown in FIG. 15, the signal processing circuit 74 is composed of a correction circuit 76 and a bias adding circuit 77. The correction circuit 76 performs strength conversion of the electric signal from the microphone 73 based on the electric input-optical output characteristic of the optical recording head 75 and the exposure-development density characteristic of the photosensitive recording medium 8. The bias adding circuit 77 gives a constant DC component offset to the intensity-converted signal from the correction circuit 76, and sends the signal to the optical recording head 75.

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. 23, 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.

Furthermore, 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. 24, 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

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. 25, the captured image formed by the surface imaging optical system 9 is filtered by the filters 11R, 11G, and 11B, and the R optical image 19R, the G optical image 19G, and the B optical image 19G of each component are obtained. 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

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.

With the above configuration, 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. 26 (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.

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 with reference to FIG. 10, the photosensitive recording medium 8 is moved at a constant speed (v) at a constant speed moving portion,
The developing / fixing unit 20 applies a developing / fixing liquid.
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.

The pitch p of the arrangement of the frames 19 is set to 10 mm which is ⅓ of the first embodiment, and in this embodiment also, the imaging rate = 30 frames / sec according to the NTSC standard of 30 frames / sec. Also in such an imaging unit, the operation shown in FIGS. 8B and 8C described above is repeated at 1/30 second intervals, and
As shown in (A), the optical shutter 10 is opened at the timing when the intermittent moving section 8a is stationary, and as shown in (B), the intermittent moving section 8a is moved at the timing when the optical shutter 10 is closed. As a result, 1/3 of the captured image

The imaging time is 15 minutes, which is three times as long as that in the first embodiment.
