Description

Detailed Description of the Invention (Industrial Application Field) The present invention converts image information with a predetermined aspect ratio (for example, 9:1G) into image information with a different aspect ratio (for example, 3:4). The present invention further relates to an image information magnetic recording/reproducing apparatus that converts the aspect ratio (for example, 9:16) of image information recorded on a magnetic recording medium and reproduced from the image information to obtain image information of the original aspect ratio. The present invention relates to such an image information magnetic recording medium and an image information magnetic reproducing apparatus for reproducing the same.

(Prior Art) Conventionally, television video signals of current standard formats such as the NTSC format have been operated with the aspect ratio of the display screen size determined to be 3=4.

In addition, in recent years, the era of home theaters has come, and the image quality of television signals has improved and screens have become larger (
large-screen television receivers, etc.), but the above-mentioned NT
Television video signals based on the SC system have an aspect ratio of 3.
:Compliant with 4.

By the way, considering the range of human visual field, a large screen of 100 inches or more, such as a projection screen of a projection display device (hereinafter referred to as a projector), has a horizontally elongated and wide screen ( For example, an aspect ratio of 9:16) is desirable. This horizontal wide screen is known to match the human field of view, making it easier to see, more natural, more realistic, and more powerful. Also, the cinema scope of the movie is a horizontal wide screen.

Due to these circumstances, high-definition video such as ``high-definition wide television'' has a horizontally long wide screen with an aspect ratio of 9:16.

(Problem to be solved by the invention) However, since the aspect ratio of horizontally wide screen high-definition video such as the above-mentioned high-definition (high-definition wide-screen television) is the same as that of the standard format, the current standard format is is not compatible with

Therefore, in order to obtain high-quality high-definition video, a horizontally long, wide-viewing-angle subject or video source (cinescope, etc.) is imaged with a television camera using a special image pickup tube, and the imaged video signal is is recorded on a recording medium using a recording/playback device such as a special video tape recorder (VTR), which is played back.The played video signal is then displayed on a special projector with a different deflection system such as a cathode ray tube (CRT). It had to be displayed on the screen by the device.

Therefore, in the above system, special high-definition television cameras, VTRs, projectors, etc. must be provided, and these are all expensive, resulting in a considerable cost for the system.

On the other hand, in recent years, the number of pixels in image pickup devices such as charge-coupled devices (CODs) has increased, and the mass production of devices has led to lower prices, so consumer television cameras have become high-quality and low-priced. Furthermore, VTRs for consumer use have been commercialized to provide image quality comparable to that of commercial VTRs by widening the luminance signal band to improve image quality, and these have also become cheaper due to mass production. Projectors have also been commercialized in which a liquid crystal panel is configured as a three-primary color light shutter, and the image quality is comparable to that of a cathode ray tube (CRT) in terms of contrast and color reproducibility.

However, the above-mentioned consumer television cameras, consumer VTRs, and projectors are all based on the current standard system, and therefore are not compatible with high-definition, horizontally wide-screen cameras.

In addition, in order to display a horizontally wide screen such as the above-mentioned cinescope on a standard preview screen, conventionally the aspect ratio has been electrically changed by changing the deflection system of the image pickup tube or Braun'f1 (CRT). Another method, as shown in FIG. 10, is to make the top and bottom of the screen black. In this case, from a simple point of view, the percentage of the part that is blacked out and missing from the screen is 25% (one quarter) of the entire screen.
) can also be reached. This is extremely wasteful from the point of view of effective use of image information that can be displayed on the screen.

Therefore, the present invention solves the problems of the conventional technology described above,
Compliant with current standard methods, simple configuration and low cost.
For example, it is possible to carry an image of an object or video source (cinescope, etc.) with a wide horizontal viewing angle, record it on a magnetic recording medium, and play it back to display a high-quality video on a horizontal wide screen. An object of the present invention is to provide an image information magnetic recording/reproducing device and an image information magnetic recording medium that do not waste image information that can be displayed on a screen.
