いる。Television signals have made great advances, especially with the invention of the VTR, and continue to this day, and they have a great advantage, especially compared to film, in terms of immediacy of playback. The method of shooting, developing, editing, and projecting using film still occupies the mainstream in the film industry.

るものである。Conventional configurations and their problems Film movies are completed through complex processes such as shooting, developing, editing, recording, and printing. The method used to display the completed film was to project it onto a screen in a dark room. However, this requires a dark and specific room with a projector installed.
Operation in a bright room, simple movement of the projector, and image processing during projection were extremely difficult. Therefore, as an alternative to film, a method using a so-called video signal using a VTR and, for example, a glossy television may be considered.・Purpose of the Invention The present invention is intended to ensure that when a reproduced signal from a VTR is projected on a video projector, the appearance of the picture does not differ greatly from the projected image of a movie film. It is.

In the drawing, the composite video signal is not directly processed, but is divided into Y, I@Q in the NTS'C system, and Y, IJ, and ■ in the PAL system (hereinafter referred to as baseband signals), and is then recorded and played back.

The baseband signal sent from the VTR 1 can be switched from the transmission VTR 1 to the transmission VTR 2. Below, from the sending VTR 2,
To the sending VTR 3, from the sending VTR 3 to the sending VTR
The switching to 1 is performed sequentially. The switched baseband signal is encoded into a composite video signal by an encoder circuit built in the control device 4, sent to the video projector 6, and projected onto the screen 7. The monitor television receiver 5 is a television for monitoring that is sent to the video projector 6, and the transmission progress display control console 8 controls each V

画像の許力を制限していた。Now, the images on these movie video playback devices are
The feel of the picture was very different from the film image even on the same screen, and it was clearly possible to distinguish between the video screen and the film screen. This difference is unacceptable to those who are accustomed to film-based screens, and the psychological sensation is extremely different.
Image permissions were limited.
各種の実験の結果、この主たる原因は色温度の設定にあ

にその色温度は、５６００’にでる。As a result of various experiments, it was found that the main cause of this was the color temperature setting. For example, in the case of film, the color temperature is generally 5600'.

た。On the other hand, in the case of a video system, for example, the camera is 39000°, the monitor TV is +5MPCD at 9600°, the video projector Fi is +20MPCD at 9000°,
There is a clear difference. Furthermore, if you investigate in detail, you can set the color temperature of these video 7 stems to any color temperature that satisfies the movie industry (3200°K (for TV movies) to 56000K (for movies)). It turns out that if you do this, you can create a feeling that is very similar to film, and you can eliminate the problems caused by the differences between the two mentioned above.

あって′も、同様に適用することが出来る。Effects of the Invention As described above, according to the present invention, in a device that selectively projects images from a movie film and an image from a VTR on the same screen, many viewers can enjoy almost the same feeling as the film. I was able to get it from the test results. Note that this concept can be similarly applied to other video systems used in conjunction with film.
