Abstract
By setting an area for displaying OSD data, a high-intensity part of this area is highlighted and an area which is not to be highlighted is set. Also, by performing translucent display of the OSD data and natural-image data, an area which is not to be highlighted can be set.
Claims7
A video signal processing apparatus comprising:
- a first storage unit configured to store first image data;
- a second storage unit configured to store second image data;
- a comparing unit configured to compare luminance-signal component data in the first image data with a predetermined level;
- a modifying unit configured to modify the second image data based on the output from the comparing unit;
- and
- a synthesizing unit configured to synthesize the first image data and the second image data modified by the modifying unit and output the synthesized data,
- wherein the modifying unit blinks the second image data in a blink cycle, in which relative relations of a frame rate of the video signal and the blink cycle are variable, and
- wherein the modifying unit is configured to generate different patterns for at least two areas of a high-intensity area, a low-intensity area, and a normal-intensity area of the first image data, and superimpose the patterns on the first image data.

A video signal processing apparatus comprising:
- a first storage unit configured to store first image data;
- a second storage unit configured to store second image data;
- a comparing unit configured to compare luminance-signal component data in the first image data with a predetermined level;
- a selecting unit configured to select the second image data or third image data based on the output from the comparing unit in a blink cycle which is variable;
- and
- a synthesizing unit configured to synthesize the first image data and the image data selected by the selecting unit, and
- a generating unit configured to generate the third image data which has different patterns for at least two areas of a high-intensity area, a low-intensity area, and a normal-intensity area of the first image data.
