Abstract
(1) A color misregistration detector comprises a matrix circuit for inputting a color image signal acquired on a time-series basis and generating color difference signals R-Y and B-Y, differentiating circuits for differentiating the color difference signals and detecting the quantities of changes in the color difference signals, comparators for detecting quantities of changes exceeding set values among said quantities of changes in the color differences, a counter circuit for counting the number of points indicating large changes in color differences these comparators compare and detect, and a CPU for monitoring a time-series change in the count and identifies presence of color misregistration. (2) A color misregistration easing system includes a correcting means for synthesizing a raw color image signal and a color image signal of a last image without color misregistration or selecting either of the signals according to the result of the identification the CPU provides.
