Abstract
A color video apparatus for displaying on-screen a hue control state of a color video signal. The apparatus includes a key input portion for inputting a hue control command of the color video signal displayed on the screen, and an on-screen-display (OSD) signal generator for generating an OSD signal for visually representing a reference color and for displaying an occupancy which indicates the degree to which the reference color contributes to the expression of a hue control state with respect to a plurality of reference colors used for expression of the hue control state, in response to the hue control command of the key input portion.
Claims8
A color video apparatus for displaying a hue control state of a color video signal on a screen, the color video apparatus comprising:
- 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 which visually represents a reference color among a plurality of reference colors used for expression of the hue control state and which displays an occupancy for indicating a degree of contribution to expression of a hue control state of said reference color compared with occupancies of said plurality of reference colors, in response to said hue control command of said input means;
- wherein said reference color and another one of said plurality of reference colors are simultaneously displayed in a single composite image;
- wherein said reference color occupies one portion of said single composite image and said another one of said plurality of reference colors occupies another portion of said single composite image;
- wherein an amount of said single composite image occupied by said reference color corresponds to an occupancy of said reference color and an amount of said single composite image occupied by said another one of said plurality of reference colors corresponds to an occupancy of said another one of said plurality of reference colors;
- and
- wherein only when an occupancy of said reference color is the same as an occupancy of said another one of said plurality of reference colors said OSD signal generation means generates an OSD signal for displaying a color which is different from said reference color and said another one of said plurality of reference colors in one of said one portion and said another portion of said single composite image so as to allow a user to more easily recognize an equivalence of an occupancy between said reference color and said another one of said plurality of reference colors.
A color video apparatus for displaying a hue control state of a color video signal on a screen, the color video apparatus comprising:
- 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 in response to said hue control command of said input means;
- wherein said OSD signal visually represents a composite image of a first reference color and a second reference color;
- wherein said first reference color occupies a first portion of said composite image and said second reference color occupies substantially all of a remaining portion of said composite image;
- wherein an occupancy of at least one of said first reference color and said second reference color corresponds to a size of a respective said first portion and said substantially all of a remaining portion corresponding to a degree of said occupancy;
- wherein said occupancy of said at least one of said first reference color and said second reference color is represented by at least one of a numeral and a character corresponding to a degree of said occupancy;
- and
- wherein only when said occupancy of a selected one of said first reference color and said second reference color is the same as an occupancy of the other one of said first reference color and said second reference color, a third color having a hue that is different from said first reference color and said second reference color is displayed to indicate such equivalence of occupancy.
