BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup device for recording a moving image of the outside world on a photosensitive recording medium, and an image pickup / reproduction.

[0002]

2. Description of the Related Art Conventionally, a so-called 8 mm camera has been known as an image pickup device for photosensitively recording a moving image of the outside world. This 8
The millimeter camera is provided with a frame feed mechanism, and the film is intermittently conveyed by this frame feed mechanism. Then, when the intermittently conveyed film comes to rest, the shutter is opened and the imaged image formed by the optical system is projected onto the film in a still state. Also, with the shutter closed, the frame feed mechanism is operated to transport the film, and while repeating the transport and still of this film, the shutter is opened only when the film is stationary, so that the still images of the captured images are continuously transferred. To make a photosensitive recording.

[0003]

However, in the 8 mm camera, since the film is repeatedly conveyed and stopped by the intermittent operation of the mechanical frame feed mechanism, the vibration and the operation noise are not generated. It will inevitably occur. In addition, the mechanism is complicated and the operating speed is naturally limited.

The present invention has been made in view of such conventional problems, and provides an image pickup apparatus and an image pickup / playback apparatus capable of photosensitive recording a still image without intermittent movement of the photosensitive recording medium. It is intended to be provided.

[0005]

In order to solve the above problems, in an image pickup apparatus according to the present invention, a conveying means for conveying a photosensitive recording medium in a predetermined direction, and an image to be picked up are recorded on the photosensitive recording medium. An optical system for projecting on a part, an optical shutter for opening and closing to control the projection time of the optical system, and a projection image projected on a part of the photosensitive recording medium from the optical system at the time of opening the optical shutter, It has a scanning optical means that moves in a state where there is no relative movement with respect to the part, and a developing and fixing processing means for developing and fixing the photosensitive recording medium having the projected image exposed.

Further, in the image pickup / reproducing apparatus according to the present invention, the first conveying means for conveying the photosensitive recording medium in a predetermined direction, and the optical system for projecting the image to be captured onto a part of the photosensitive recording medium. An optical shutter that opens and closes to control the projection time of the optical system; and a projection image projected on a part of the photosensitive recording medium by the optical system when the optical shutter opens to move relative to the part. Scanning optical means that moves in the absence of light, a developing and fixing processing means that develops and fixes the photosensitive recording medium that has been exposed to the projected image, and the still image is continuously developed and fixed by this developing and fixing means. Second conveying means for conveying the recorded photosensitive recording medium and the still image recorded on the recorded photosensitive recording medium conveyed by the second conveying means are sequentially read to obtain an electric signal. Reading means for converting, on the basis of the electric signal converted by the reading means, and an image signal generating means for generating an image signal corresponding to a predetermined output device.

[0007]

In the above construction, when the optical shutter is opened, the optical system projects a picked-up image on a part of the photosensitive recording medium which is being conveyed in the predetermined direction by the conveying means. Then, the imaging scanning optical means moves the projection image projected by the optical system in a state where there is no relative movement with the part. Therefore, even if the photosensitive recording medium is continuously conveyed without stopping, the projection image at the time of the opening operation of the optical shutter is exposed as a still image on the part. Then, the photosensitive recording medium on which the still image has been exposed is subjected to development and fixing processing by the development and fixing processing means.

In the image pickup / playback apparatus having the above-mentioned structure, the recorded photosensitive recording medium obtained by the image pickup apparatus is fed and driven by the driving means, the still image is read by the reading means, and converted into an electric signal. To do. Then, the image signal generating means generates an image signal corresponding to a predetermined output device based on the electric signal, and thus sends this image signal to the predetermined output device, thereby generating a moving image of continuous still images. It is possible to see.

Medium transport block 1 on the reproduction unit 31 side
In No. 01, as shown in FIG. 7, the supply roll 6 and the storage roll 7 are rotatably arranged at an interval.
A pair of pinch rollers 15 and 16 are arranged near the rolls 6 and 7, respectively.
A recorded recording medium 38, which will be described later, is sandwiched between 5 and 16. A first path length adjusting mechanism 17 and a second path length adjusting mechanism 18 are provided near the inner sides of the pinch rollers 15 and 16, respectively. The recorded recording medium 3 extending between the two path length adjusting mechanisms 17 and 18
An image is formed by the surface image-forming optical system 9 on the intermittent moving portion 8a of the image forming device 8.

The path length adjusting mechanisms 17 and 18 are a pair of fixed rollers 17a, 17b, 18a and 18b which come into contact with the base 11 side (see FIG. 3A) of the recorded recording medium 38.
And movable rollers 17c and 18c which are movable in a direction orthogonal to the recorded recording medium 38 on an extension line between the fixed rollers 17a, 17b, 18a and 18b,
The movable rollers 17c and 18c are in pressure contact with the R photosensitive layer 12 side of the recorded recording medium 38. This movable roller 17
c and 18c are reciprocally driven in the above direction by an actuator (not shown), and the pinch rollers 15 and 16 and the storage roll 7 are rotationally driven at the same linear velocity via a motor (not shown) and a reduction mechanism. The operations of these actuators and motors are controlled by the main controller 2 so that the adjacent fixed rollers 17b, 1
Intermittent movement part 8 of recorded recording medium 38 extending between 8a
a is driven intermittently as described later.

In the present embodiment having the above-mentioned structure, when image pickup is started, the storage roll 7 rotates, the photosensitive recording medium 8 is conveyed to the storage roll 7 side at a constant speed V1, and the prism 116 moves in the rot direction. To start rotating. on the other hand,
The optical shutter 10 repeats the opening / closing operation at a constant cycle. Then, when the optical shutter 10 is opened, the prism 116 is rotated to the projection start position shown in FIG. Therefore, the imaged image coming from the surface imaging optical system 9 through the optical shutter 10 enters from the side surface 16a on the optical shutter 10 side, and is projected as a projected image 118 on the photosensitive recording medium 8 from the opposite side surface 16c. To be done.

The prism 116 is the optical shutter 1.
0 is opened, the projection start position [Fig.
(A)] to the projection intermediate position [(B) in the figure] and the projection end position [(C) in the figure] continuously, whereby the projected image 118 moves on the photosensitive recording medium 8 at the speed V2. Moving. At this time, as described above with reference to FIG. 4, the photosensitive recording medium 8 moves at a velocity V equal to the moving velocity V2 of the projected image 118.
No. 1 is conveyed in the same direction. Therefore, there is no relative movement of the projected image 118 on the photosensitive recording medium 8 moving at the speed V1, and the projected image 118 is sensitized and recorded on the photosensitive recording medium 8 as a still image.

That is, as described above, the prism 116 is configured so that the projected image 118 moves on the photosensitive recording medium 8 at the speed V2 while continuously transporting the photosensitive recording medium 8 at the speed V1 without being stationary. By rotating, the still images of the imaged image at the timing when the optical shutter 10 is opened can be continuously exposed and recorded on the photosensitive recording medium 8. Therefore, a mechanical frame feeding mechanism for moving and stopping the photosensitive recording medium 8 is not required, and it is possible to eliminate the generation of vibration and operating noise, and to simplify the mechanism and increase the operating speed.

On the other hand, in the developing and fixing unit 20, the lid of the tank 21 is driven to open by 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. 9, 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.

In this way, the imaged 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 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.

When the reproduction of the imaged result is started, the recorded recording medium 38, on which the still image is developed and fixed on the photosensitive recording medium 8 by the above-described image capturing, is rewound to the supply roll 6 side, and after that, , And set as shown in FIG. At this time, both movable rollers 17c, 18
As shown in the figure, c is the fixed rollers 17a, 17b,
It is stopped at the same neutral position N which is retracted by a predetermined distance from 18a and 18b. Then, when the reproduction is started, the motor is started in accordance with the instruction from the main controller 2, whereby the pinch rollers 15 and 16 and the storage roll 7 start to rotate at the same linear velocity, whereby the recorded recording medium 38 is recorded. Is sent to the storage roll 7. Then, at the same time when the pinch rollers 15 and 16 and the storage roll 7 start rotating, the actuator operates, and as shown in FIG. 10B, the movable roller 17c of the first path length adjusting mechanism 17 has already recorded. In the backward direction away from the recording medium 38,
The movable roller 18c of the second path length adjusting mechanism 18 simultaneously moves from the neutral position N by the equal distance L1 in the forward direction toward the recorded recording medium 38.

Therefore, the recorded recording medium 38 pulled out from the supply roll 6 in accordance with the rotation of one of the pinch rollers 15 during that time, the path length thereof is lengthened by the backward movement of the movable roller 17b, and the pulled-out amount is increased. Be absorbed. Further, when the movable roller 18c moves forward, the path length of the recorded recording medium 38 is shortened on the side of the second path length adjusting mechanism 18, and the surplus generated by this is caused by the rotation of the pinch roller 16 and the storage roll 7. Along with this, it is wound up on the storage roll 7. Therefore, during this period, the intermittent moving portion 8a of the recorded recording medium 38 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 seconds elapse, the actuator operates in the opposite direction to the above, and as shown in FIG. In the movable roller 17c of the first path length adjusting mechanism 17, the movable roller 18c of the second path length adjusting mechanism 18 moves in the forward direction approaching the recorded recording medium 38.
The recording medium 38 and the recording medium 38 are simultaneously moved in the backward direction away from the recorded recording medium 38 by an equal distance L2.

Therefore, on the first path length adjusting mechanism 17 side, the path length of the recorded recording medium 38 is shortened, and at the same time, on the second path length adjusting mechanism 18 side, the path length of the recorded recording medium 38 is long. Turn into. Therefore, 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 same time, the fixed rollers 17b and 18 are fixed.
The intermittent moving portion 38a interposed between a is absorbed by the second path length adjusting mechanism 18 side.

The above operation shown in FIGS.
By repeating the operation at 1/30 second intervals, the recorded recording medium 38 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 38a is being moved.
Are fixed at 1/30 second intervals, and both fixed rollers 17b and 18a
Still in the meantime. 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 1 / 30th.
At a second interval, the stationary rollers 17b and 18a stand still.
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.・ ・
The still image recorded in 1 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 of turning 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.

That is, by using this image pickup / reproduction device 61, as shown in FIG.
“2. Automatic development” → “3. Replay” can be performed, and the moving image f of the captured image F can be visually recognized on the television receiver 65,
Still images can be printed out by the video printer 66. 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 conveying speed V1 of the photosensitive recording medium 8 is constant, but if the relationship of V1 = V2 can be maintained during the opening operation of the optical shutter 10, the conveying speed V1 is always constant. No need. Although the prism 116 has a quadrangular cross section in the embodiment, it may have another polygonal shape such as a hexagonal or octagonal cross section. Further, each of the side surfaces 116a to 116d may have a curved surface configuration instead of a planar configuration, and a fixed auxiliary optical unit such as an f-θ lens may be added.

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.

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.
