Abstract
The image processing apparatus includes an RGB-YUV converter for converting a color image into a luminance signal and a color difference signal and a YUV false color remover for removing false color based on the luminance signal Y and the color difference signals U, V. The false color remover includes an edge intensity calculator for calculating edge intensity based on the luminance signal Y, a modulation coefficient calculator for calculating a modulation coefficient so that a degree of modulation is greater as the edge intensity is higher, and a UV modulator for modulating a color difference signal having a value smaller than a prescribed threshold based on the degree of modulation.
