Document Type and Number:
Japanese Patent JP4374057
Kind Code:
B2
Abstract:
According to one embodiment, an embodiment of the invention is applicable to various input video signals, prevents image quality degradation in a signal conversion process, and maintains image quality. A front stage unit has a first video signal processing circuit, which reduces noise and performs IP conversion in response to a first image processing control signal from a first control circuit. A rear stage unit has a second video signal processing circuit, which executes frame rate conversion in response to a second image processing control signal from a second control circuit. An arithmetic circuit functions so that the contents of the first image processing control signal exerts an influence upon the second image processing control signal.
