Patent ID: 7251057

Claim:
A digital camera which generates a color relating signal for display on the basis of a color information signal corresponding to a photographed object image, comprising: a color saturation degree detector for detecting a color saturation degree of the color information signal, said color saturation degree being indicative of a degree that the number of pixels in each of which the color out of the color and the luminance is saturated is large or small; a reducer for reducing dynamic range of the color relating signal on the basis of the color saturation degree; an operator for performing an operation according to a predetermined coefficient on the color information signal so as to generate the color relating signal, wherein said reducer includes an adjuster for adjusting the predetermined coefficient on the basis of the color saturation degree, and wherein said color saturation degree detector detects a first number of pixels in which a level of the color information signal exceeds a threshold value as the color saturation degree; a generator for generating a luminance signal on the basis of the color information signal; and a luminance saturation degree detector for detecting a second number of pixels in which the level of the luminance signal exceeds a threshold value as the luminance saturation degree, wherein said adjuster includes a subtracter for subtracting said second number of pixels from said first number of pixels, and a determiner for determining the predetermined coefficient on the basis of a subtraction result by said subtracter.
