Abstract

PURPOSE:To easily recognize a proper hue adjusting position by displaying playing the bars of red color and green color on a screen and arraying the bars of a third color in a straight line between the bars of red color and the bars of green color to display on the screen. CONSTITUTION:In the case of adjusting hues, when the level up button 46 or the level down button 17 of a commander is depressed, the bar display illustrated in figure is appeared. Namely, the red bars Rb, yellow bars Yb and green bars Gb are displayed on the screen and also a segment Sg to which the shape is different from the bars is displayed on it. If the segment Sg positions in the middle of the area Yl of yellow bard Yb, the segment Sg is made to turn yellow. When the level down button 46 is kept depressed, the segment Sg moves to a lift side and on the other hand when the level up button 47 is kept depressed, the segment Sg moves to a right side. The area Yl of the yellow bars Yb expresses the range of a proper state and if the segment Sg is within the area Yl the state is proper one.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a color tone display device for a television receiver.

[Summary of the invention]

The present invention is a color tone display device for a television receiver, in which red and green bars arranged in a straight line are displayed on the screen, and a third color bar is arranged between the red and green bars. are arranged in a straight line and displayed on the screen,
By displaying segments of different shapes than bars on the screen so that they can be moved in a straight line, and by making the segment color the same as the bar color in each colored bar area, the appropriate range can be determined. It is designed to be easy to understand and improve visibility.

[Conventional technology]

For example, as shown in Japanese Unexamined Patent Application Publication No. 124633/1982, the display of the volume level and the adjustment status of image quality such as color tone, color saturation, brightness, sharpness, etc. are arranged on the screen. A television receiver is known that displays a bar.

For example, when performing color tone adjustment, in a conventional television receiver, as shown in FIG.
, Rb, ... and the green bar Gb.

Gb, . . . are arranged on the - column and displayed on the screen.

The state of the color tone is indicated by the ratio of the length of the region Rj2 where the red bars Rb, Rb, . . . are arranged and the length of the region GIl where the green bars Gb, Gb, . The screen becomes reddish as the number of red bars Rb increases and the area RA where the red bars Rb are arranged becomes longer.
The screen becomes greener as the region Gl in which b is arranged becomes longer.

In the standard state, the area R7! where the red bars Rb are arranged is the area R7!
and the length of the region Gp where the green bars cb are arranged are approximately equal.

[Problem that the invention seeks to solve]

As mentioned above, the length of the region Rβ of the red bar Rb and the region G7 of the green bar Gb! If the state of the color tone is displayed based on the ratio to the length of the color, it is difficult for the user to recognize the extent to which the color tone is appropriate. In other words, if the length of the area Rρ where the red bars Rb are arranged and the length of the area GN where the green bars Gb are arranged are approximately equal, it is possible to recognize and recognize that the state is correct, but to what extent can the adjustment be made? I don't know if it's acceptable.

Therefore, it is an object of the present invention to provide a color display device that allows the user to easily determine the appropriate adjustment position.

Further, in the conventional par display, the shape of the red bar Rb and the shape of the green bar Gb are the same, and the color tone is displayed only by changing the color. Therefore, visibility is not good.

Therefore, another object of the present invention is to provide a color tone display device with good visibility.

[Means for solving problems]

This invention displays red and green bars arranged in a straight line on the screen, and a third bar between the red and green bars.
Bars of different colors are arranged in a straight line and displayed on the screen, segments of different shapes from the bars are displayed on the screen so that they can be moved in the direction of the straight line, and the color of the segments is arranged in the area of each colored bar. This is a color tone display device characterized in that the color is the same as the color of the bar.

[Effect]

In the standard state, segments 1-5g are located in the middle of the area Yρ of the yellow bar Yb, and the color of the segment Sg is yellow. As the level down button 46 is pressed, the segment Sg is moved toward the area RA of the red bar Rb on the left. As the segment Sg is moved to the left, the color of the screen becomes reddish. When the segment Sg enters the region R/ of the red bar Rb, the color of the segment Sg changes to red.

Press level up button 47 (and segment S
g is moved toward the area Gβ of the green bar Gb on the right. As segment Sg is moved to the right, the color of the screen becomes greener.

When the segments 1-3g enter the area GN of the green bar Gb, the color of the segment Sg changes to green.

Area Y7 of yellow bar Yb! indicates the range of suitable conditions. If the segment Sg is within the area Yl of the yellow bar yb, it is in a proper state.
