DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a television receiver for displaying an image based on a video signal having an aspect ratio different from that of a video display surface.

[0002]

2. Description of the Related Art In standard television broadcasting, when a video signal is received by a receiver and an image is displayed on a screen such as a CRT or a liquid crystal display panel, the aspect ratio (aspect ratio) of the projected screen is displayed. ) Is determined to be 4: 3. On the other hand, in the high-definition television broadcasting (high-definition broadcasting), the resolution is about twice as large as that of the standard system, and the aspect ratio is 16: 9, which is wider than the standard system 4: 3. The image is displayed on the image display surface of the camera to enhance the realism of the image projected there.

[0003] By the way, even in a television receiver (high-vision receiver) for receiving a high-definition broadcast,
A standard 4: 3 video signal can be received and displayed on the screen. However, it receives a video signal with an aspect ratio different from that of the video display surface,
When projected on the central portion of a 6: 9 horizontally long screen, a black or gray band-like region having no image and having an equal width is generated on both left and right sides of the image display surface. If an image based on a video signal having a different aspect ratio is to be displayed on the display surface of a horizontally long CRT or a screen display area of a liquid crystal display panel without forming such a band-like area, the image itself is deformed. Alternatively, it is necessary to cut the upper and lower portions of the standard 4: 3 image without deformation.

[0004] A television receiver having a 4: 3 video display surface can similarly display a high-definition broadcast image, but even in this case, the video display surface is determined based on the difference in the aspect ratio of the video signal. A black or gray band without image is formed on both upper and lower sides.

[0005]

As described above, in addition to the case of receiving and displaying a video signal of a standard system in a high-vision receiver, an image is generally formed based on a video signal having an aspect ratio different from that of a video display surface. Even in a television receiver for display, a black or gray band-like area without an image generated inside the connection area of the front panel with the image display surface becomes a boundary between the front panel and the screen, and gives a sense of discomfort to the viewer. It will be an embrace.

[0006] In particular, when the front panel is integrally formed with the receiver cabinet, and it is colored in a bright color, and the difference between the color and the gloss in the non-image area is large, The boundary between the front panel and the screen is conspicuous, and the sense of incongruity is further increased, which impairs the realism of the image projected there.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a method for receiving a video signal having an aspect ratio different from the effective screen size of a video display surface of a receiver. An object of the present invention is to provide a television receiver in which a person who views an image projected based on the image can feel that the size of the video display surface itself has changed.

[0008]

According to a first aspect of the present invention, there is provided a television receiver for displaying an image based on a video signal having an aspect ratio different from that of a video display surface. At least a part of the connection area between the front panel and the image display surface, which is arranged around the display surface, is colored the same as or similar to the color and gloss of the image display surface when not displayed. It is.

In a television receiver according to a second aspect of the present invention, the front panel is configured to be detachable from a receiver cabinet.

According to a third aspect of the present invention, the coloration of the front panel is black or gray.

In a television receiver according to a fourth aspect of the present invention, the image display surface is a CRT or a liquid crystal display panel.
