ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a color video apparatus for displaying on-screen a hue control state.
When a user changes a setting of a television set or a video cassette recorder (VCR), the television or VCR displays an on-screen-display (OSD) signal which shows the new setting. For controlling the tint or hue, the color video apparatus displays on-screen the setting of the tint or hue, and the user adjusts the setting by referring to the displayed setting and providing appropriate key input. An existing color video apparatus on-screen-displays a present hue control state through an indicator which indicates the degree of color unbalance toward a particular color. With this system, it is difficult to recognize the color control setting. Additionally, it is very difficult to recognize the color control state displayed on a screen when the color video apparatus is controlled by a remote controller far away from the screen. It is also very difficult to recognize the color control state when the color of the on-screen display signal is close to the color of the image displayed on the screen.
SUMMARY OF THE INVENTION
To solve the above problems, it is an object of the present invention to provide a color video apparatus for displaying on-screen a color by which the hue is controlled and displaying on-screen the degree of contribution to hue expression of the color.
To accomplish the above object of the present invention, there is provided a color video apparatus for on-screen-displaying a hue control state of a color video signal on a screen, the color video apparatus comprising:
key input means for inputting a hue control command of the color video signal displayed on the screen; and
on-screen-display (OSD) signal generation means for generating an OSD signal for representing a reference color visually, together with an occupancy for indicating a degree of contribution to expression of a hue control state of the reference color among a plurality of reference colors used for expression of the hue control state, in response to the hue control command of the key input means.
