Abstract
A video input interface receives video data. An OSD circuit draws an on screen display (OSD) character on the video data. The visibility detector checks whether the visibility of the OSD character is good or poor. A determination criterion for the visibility dynamically changes in a manner that depends on a background of the OSD character.
Claims14
A semiconductor device comprising:
- a video input interface structured to receive video data;
- an on screen display (OSD) circuit structured to draw an OSD character on the video data;
- and
- a visibility detector structured to check whether visibility of the OSD character is good or poor, wherein
- a determination criterion for the visibility dynamically changes in a manner that depends on a background of the OSD character.
