Method and circuit for correction of horizontal edges |
摘要 |
A circuit for correcting horizontal edges in a digital image signal processing system, includes: three filtering circuits for filtering an input luminance signal to obtain a low frequency component, a medium frequency component and a high frequency component, respectively; three controller circuits for controlling gain of the low frequency component signal, the medium frequency component signal and the high frequency component signal on the basis of three corresponding control signals to produce three respective frequency signals and three mixing circuits for mixing the input luminance signal with the resepctive frequency signals to thereby produce an output luminance signal corrected in horizontal edges.
