Is driven by the main controller 2
Controlled by.

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,
As shown in the figure, both movable rollers 17c and 18c are stopped at the same neutral position N retracted from the fixed rollers 17a, 17b, 18a and 18b by a predetermined distance.

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 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 ...

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
According to G and B, the storage roll 7 is developed while exhibiting an absorption spectrum having different wavelengths λ1, λ2 and λ3 as peaks.
Is taken up by.

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.

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)). When the rewinding is completed, the recorded storage medium 38 is stopped at the position where the starting end of the top 19 on the side of the transport direction A is projected on the monochrome line sensor 39.

Then, when the reproduction is started, the main controller 2 stops the pinch rollers 102, 102, and the light source driver 36a while keeping the recorded recording medium 8 stationary.
To operate. Then, the light source driver 36a detects that the frame 19 of the recorded recording medium 8 remains in the state shown in FIG.
As shown in (B), pulses PR, PG, and PG are generated to sequentially blink the light sources 36R, 36G, and 36B.
Then, first, when the light source 36R is turned on by the generation of the pulse PR, the light of the wavelength λ1 is irradiated and the R component of the still image stored in the frame 19 is imaged by the imaging optical system 37, and as a result, the monochrome image is obtained. The R component, which is one line component of the still image, is projected on the line sensor 39.

Then, the sensor driver 40 drives the monochrome line sensor 39 at the timing when the light source 36R is instructed by the main controller 2, and the pre-processing circuit 41 drives the accumulated charge by photoelectric conversion of the monochrome line sensor 39. Output to. 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 converted into digital image data by the A / D converter 47 and stored in the memory 49. First, digital image data of the R component and one line component is stored in the memory 49.

Further, the light source driver 36a generates the pulse PG when the digital image data of the R component and one line component is stored in the memory 49, and thereby the light source 36G is turned on. Then, the light of wavelength λ2 is emitted, and the G component of the still image stored in the frame 19 is projected by the imaging optical system 37 onto the monochrome line sensor 39. Therefore, in the same manner as described above, the digital image data of the G component and the same one line component is stored in the memory 4
9 is stored. Further, the light source driver 36a, when the digital image data of the G component and the same one line component is stored in the memory 49, the pulse PB
Is generated, which causes the light source 36B to light up. Then
When the light of wavelength λ3 is irradiated, the B component of the still image stored in the frame 19 is projected on the monochrome line sensor 39 by the imaging optical system 37, and similarly, the B component and the same one line are projected. Digital image data of the component is in memory 4
9 is stored.

When the R, G, and B digital image data of one line component are stored in the memory 49 in this manner, the main controller 2 causes the pinch roller 102,
102 is operated to move the recorded recording medium 38 in the transport direction A at the fine pitch and then stop. As a result, the top 19 moves one pitch and stands still,
While the top 19 is stationary, each light source 36R,
36G and 36B are sequentially blinked. As a result, the following digital image data of R, G, and B of one line component is stored in the memory 49 based on the accumulated charge of the monochrome line sensor 39 at each lighting timing.

Therefore, by performing the above operation from the start end to the end of the frame 19, the memory 49 is
R, G, and B digital image data for the frames are stored. Then, the operation matrix 50 uses the R, G, and B digital image data output from the memory 49 to calculate the luminance data Y and the color difference data RY and BY.
Is calculated, and gamma correction or the like is performed at this time. Further, the luminance data Y, the color difference data RY and BY from the operation matrix 50 are analogized by the D / A converter 51, and the color encoder 46 is the analogized luminance signal Y and color difference signal RY. And BY generate and output a video signal.

On the other hand, the conveying direction A of the recorded recording medium 38
When the starting end of the next frame 19 is projected on the monochrome line sensor 39 as the camera moves to, the 1
Digital image data of R, G, and B components for each line component is stored in the memory 49, and when the pitch is fed to the end of the frame 19, R, G, B component image data for one frame is stored in the memory 49. To be done. And one frame of R, G,
When the B component image data is stored in the memory 49, the color encoder 46 sequentially outputs video signals.
Therefore, based on this sequentially 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.

That is, 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, it is possible to quickly and smoothly reproduce the moving image f of the captured image F on the television receiver 65, print the still image f ′ of the captured image F on the video printer 66, and the like.

FIG. 11 shows another embodiment of the present invention. A light source which emits all spectral components of λ1, λ2 and λ3 is provided at a portion of the recorded recording medium 38 facing the frame 19. 50 are arranged. A disc-shaped rotary filter 51 which is vertically rotated by a driving unit (not shown) is provided between the light source 50 and the top 19. The rotary filter 51 has a light source
A trisected region interposed between 0 and the frame 19 is formed. Each region is provided with a λ1 filter 51R that transmits only the λ1 spectrum component, a λ2 filter 51G that transmits only the λ2 spectrum component, and a λ3 filter 51B that transmits only the λ1 spectrum component.

In this embodiment, the light source 5 is used during reproduction.
In addition to turning on 0, the rotary filter 51 is rotated in the rot direction indicated by the arrow at the rotational speed at which the rotary filter 51 makes one rotation within the time period during which the top 19 is stationary as described above. As a result, one line component of the still image stored in the frame 19 is divided into λ1 component, λ2 component, λ3.
The component is projected on the monochrome line sensor 39. Therefore, by adopting the data conversion block 35 and the transport block 101 shown in FIG. 7 as they are, the digital image data of λ1 component, λ2, as in the above-described embodiment.
The component digital image data and the λ3 component digital image data are stored in the memory 49, and similarly, a video signal can be generated and output by the color encoder 46.

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 units 1 and 31 may be separate image pickup devices and image reproduction devices.

In the above structure, for example, 100
If it is attempted to convert data into 30 frames / sec with a resolution of 0 × 2000 dots, the sensitivity of photoelectric conversion pixels of the monochrome line sensor 39 becomes insufficient. However, this lack of sensitivity can be solved by increasing the brightness of the light sources 36R, 36G, and 36B. Specifically, a halogen lamp, a metal halide lamp, or the like can be used. It is also effective to use a magnifying optical system as the image forming optical system 37 and increase the size of the photoelectric conversion pixel.

Further, as the resolution increases, the transfer rate of image data becomes a problem, but this problem can be solved by using a line sensor having a known multi-tap readout circuit. This is to read data independently by using a plurality of output terminals. Already, although there is to perform data transfer 16 output terminals at a data rate of 125MH _Z, it may be dealt with by further increasing the number of output terminals.

As shown in FIG. 18, the signal demodulation circuit 86 is composed of a bias removal circuit 87 and a correction circuit 88, and the bias removal circuit 87 is a circuit for removing the DC component of the offset. Further, the correction circuit 88 performs signal intensity conversion based on the optical input-electrical output characteristics of the photoelectric conversion sensor 85, and if necessary, the exposure-development density characteristics and spatial frequency-development density of the recorded recording medium 78. It is a circuit that performs correction based on characteristics.

A still image of the imaged image is continuously exposed to each frame 19 at 0 second intervals, and the photosensitive recording medium 8 is wound around the storage roll 7 at a constant speed. At this time, the sound of the surrounding environment is detected by the microphone 73 and converted into an electric signal, and the electric signal is intensity-corrected by the correction circuit 76, a DC bias is applied, and then the light amount is modulated by the optical recording head 75. The above-mentioned portion of the photosensitive recording medium 8 is irradiated. As a result, the audio track 79 is photosensitized, and the photosensitized audio track 79 is
The development and fixing process is simultaneously performed in the development and fixing unit 20 together with the still image photosensitively recorded for each frame 19.
Therefore, in this embodiment, it is possible to record not only a continuous still image of the captured image but also the sound of the surrounding environment, and a recorded recording medium capable of reproducing both the image and the sound at the same time as the image pickup is provided. Obtainable.

When the reproduction is started, as described above,
A still image recorded on each frame 19 ... Is read by the line sensors 39R, 39G, 39B, and an image signal is output from the color encoder 46.
The recorded recording medium 78 is wound around the storage roll 7. At this time, the light source 83 is turned on at the same time when 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,
The light ray conversion sensor 85 optically detects this and outputs an electric signal.

This electric signal is subjected to the intensity conversion and correction by the correction circuit 88 after the offset DC component is removed by the bias removal circuit 87, and is output as an audio signal. Therefore, according to this embodiment, the audio signals of the pre-recorded ambient environment are output together with the video signal, and the reproduction based on these signals makes it possible to listen to the audio while visually recognizing the moving image of the captured image.

During reproduction, the recorded recording medium 38 has a constant pitch as described above in the transport direction A.
However, the recorded recording medium 38 can be regarded as moving continuously because it is extremely small at this pitch, and therefore, it does not hinder the sound reproduction. .

A pair of 4a, 74b and an optical recording head 75 are provided. With this configuration, it is possible to independently record the sounds of the surrounding environment detected by the microphones 73a and 17b in the sound tracks 79a and 79b. In this configuration, the microphone 73a,
17b and the signal processing circuits 74a and 74b are provided in pairs, but a signal dividing circuit that divides the signals from the k microphones into n (n ≧ k) signals is provided to provide n voice signals. You may make it record a track. In this case, the signal dividing circuit may be one that divides the signal depending on the difference in frequency band.

FIG. 20 shows another structure of the audio reproduction block 82. In this audio reproduction block 82, only the light source 83 is single, and the imaging optical system 84a,
84b, photoelectric conversion sensors 85a and 85b, and signal demodulation circuits 86a and 86b respectively include audio tracks 79a and 79b.
One pair is provided according to the number of b. Therefore,
According to this embodiment, the sound can be reproduced for each of the sound signals recorded on the sound tracks 79a and 79b, thereby enhancing the sense of presence and the like.

As described above, in the image reproducing apparatus according to the present invention, the monochrome image is read by the monochrome line sensor for each line component and for each color component in a time division manner.
An image signal is generated based on this. Therefore, the image can be reproduced at low cost without using the magnetic-image conversion means, and further, without being restricted by environmental conditions such as a dark place. Further, since the recorded image is read directly from the photosensitive recording medium, a higher reading resolution can be obtained and the reproduction image quality can be expected to be improved, as compared with a reproducing apparatus involving magnetic-image conversion. Moreover, the one-dimensional optical-electrical converter is
Compared to the two-dimensional one, the structure is simple, a resolution of more than 1000 dots per line is easily obtained, and the cost is low. Furthermore, by combining with sub-scanning, a resolution exceeding 2 million pixels can be easily obtained. For example, by the main scanning 4500 × the sub scanning 8000,
Since even a configuration with a million pixels can be made inexpensive, high resolution and low cost can be realized in the present invention using a one-dimensional photoelectric conversion element.

In addition, by turning on the light source by applying a pulse, the turn-on timing can be controlled with high accuracy, and by using the rotary filter, further cost reduction can be achieved.
