发明名称 VIDEO SIGNAL PROCESSING APPARATUS, ENHANCEMENT GAIN GENERATING METHOD, AND ENHANCED GAIN GENERATING PROGRAM
摘要 A video signal processing apparatus includes: an enhancement gain generating section obtaining an enhancement gain for each pixel based on an luminance signal forming part of an input video signal and a predetermined enhancement gain; and an enhancing section performing a process of enhancing the luminance signal forming part of the input video signal based on the enhancement gain. The enhancement gain generating section includes a mean deviation calculating portion obtaining a mean deviation of luminance values of pixels included in a predetermined region centered at a pixel of interest that is the pixel for which the enhancement gain is to be obtained, a weighting coefficient generating portion generating a weighting coefficient for the pixel of interest according to the value of the mean deviation, and a multiplication portion multiplying the predetermined enhancement gain by the weighting coefficient to obtain the enhancement gain for the pixel of interest.
