Abstract
In the imaging apparatus, an image signal derived from an imaging element is supplied to color signal producing means so as to be separated into a R(red) color signal, a G(green) color signal and a B(blue) color signal. These R, G, B signals are supplied to color-depending frequency component changing means. While predetermined information has been stored in a memory with respect to each of the R signal, the G signal and the B signal, and the predetermined information is used in order to change a signal level of a high frequency component every R, G, B signals, the color-depending frequency component changing means extracts a high frequency component from each of the R signal, the G signal and the B signal, and then, corrects frequency components of these extracted high frequency components in such a manner that the corrected frequency characteristics may constitute relevant signals.
