Abstract

PURPOSE:To record a continuous television signal on a magnetic recording medium by assembling the shutter of an optical camera and a photographing film part integrally by sharing an optical lens part. CONSTITUTION:An optical mirror 3 is rotated by setting a rotational center 13 as a center, and the image of an object 1 is formed on the surface of an image sensor 4 with storage function, or on the surface of an optical recording medium 10 based on the position of the mirror. A signal read out from the image sensor 4 with storage function is obtained as a television signal by a video signal processing circuit 5, and furthermore, it is modulated to the signal suitable for recording. The television signal is recorded on the magnetic recording medium 8 by adding the output of the video signal processing circuit 5 on a magnetic head driving circuit 6, and adding its output on a magnetic head. In such a manner, a miniaturized device in which the features of a camera integrated type VTR and the optical camera are utilized can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a video signal recording device, and more particularly to a device for recording video signals on video tape and simultaneously on photographic film.

Conventional technology A camera-type videotape recorder (VTR), which integrates an imaging device and a magnetic recording device, is commonly used.
Image quality has been improved by separating and processing a color TV signal into a luminance signal and a color signal. On the other hand, optical cameras using photographic film are also widely used, and although they are generally capable of recording for long periods of time, this is probably because they are inferior to optical cameras in terms of image quality.

Problems to be Solved by the Invention As mentioned above, when it is desired to record moving images for a long time, it is customary to use a camera-integrated VTR, and when it is desired to record still images with excellent image quality, an optical camera is used.

Therefore, in order to achieve the above two objectives, two independent
There is the inconvenience of having to carry two devices.

Means for Solving the Problems In order to solve the above problems, the present invention provides a camera body shape VT.
By sharing the optical lens part of the R, the shutter and photographic film part of the optical camera are integrated, and an optical means for guiding the optical image to two different locations is added to integrate the camera-integrated VTR and the optical camera. It is constructed by doing.

Operation The present invention can provide a compact device that takes advantage of the respective characteristics of a camera-integrated VTR and an optical camera with the above-described configuration.

Embodiment Hereinafter, an image signal recording apparatus according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the image signal recording apparatus of the present invention, and FIG. 2 is a time chart for explaining the operation of FIG. 1.

In FIG. 1, a subject 1 is imaged by an optical lens 2 on the surface of an image sensor 4 with a storage function or an optical recording medium 10. As shown in FIG. The optical mirror 3 rotates around a rotation center 13. When the optical mirror is in the position indicated by the dotted line, the image of the subject 1 is on the surface of the image sensor with memory function 4, and when the optical mirror is in the position indicated by the solid line, the image of the subject 1 is on the surface of the optical recording medium 10. It is forming an image. The signal read from the image sensor 4 with a storage function is processed by a video signal processing circuit 5 to obtain a television signal as shown in FIG. 2(a), and is further subjected to FM modulation into a signal suitable for recording. The output of the video signal processing circuit 5 is applied to the magnetic head drive circuit 6, and the output is applied to the magnetic head to record a television signal on the magnetic recording medium 8.

As shown in FIG. 2(b), when the shutter button is pressed at the time, the output signal of the video signal processing circuit 5 is applied to the synchronization circuit 11, and the output signal is output as shown in FIG. 2(C) or (d). The optical mirror 3 comes to the position indicated by the solid line for a certain period of time Δt. At the same time, the shutter 9 in the optical camera opens and an image of the subject 1 is formed on the surface of the optical recording medium 10, forming a latent image on the optical recording medium IO such as a silver halide film.

Mirror 3 over the vertical image period as shown in FIG. 2(C)
When is at the position of the solid line, the optical image of the subject is not guided to the image sensor with memory function 4, but since the previous optical image is stored as an electrical signal, the magnetic recording medium 8 contains a continuous television set. It is possible to record it as a signal.

As explained above, even when the shutter 9 is opened for a time longer than the vertical retrace period, by using the image sensor with a memory function, the optical recording medium 10 can be continuously recorded on the magnetic recording medium 8 while moving images are being continuously recorded on the magnetic recording medium 8. images can be recorded.

As described in detail, according to the present invention, long-time moving image recording can be realized by magnetic recording and high-quality recording can be realized by optical recording in one apparatus. Furthermore, by using an image sensor with a memory function, it is possible to record continuous television signals on a magnetic recording medium even for a shutter time that exceeds the vertical retrace period.
