Abstract
The present invention discloses a method and a device for image sharpness adjustment. The device comprises a color analyzer, a color sharpness setting unit, a computing circuit, and a luminance adjusting unit. The color analyzer is for analyzing an input color signal to generate a plurality of color flags. The color sharpness setting unit is for generating a plurality of first sharpness gains according to the plurality of the color flags. The computing circuit is for generating a second sharpness gain according to the plurality of the first sharpness gains and the input color signal. The luminance adjusting unit is for adjusting a luminance signal according to the second sharpness gain.
