Color misregistration easing system for a field sequential electronic

Abstract

The present invention provides a color misregistration easing system for inputting a color image signal of a subject imaged by a field sequential type imaging device and carrying out color misregistration easing. The system comprises a color misregistration detector for using color difference signals and a luminance signal an encoder digitizes and outputs to calculate quantities of changes of color differences of time-series screens before and after, and detecting color misregistration according to the calculated quantities, an average color calculating circuit for producing averages of color differences, a decoder for using the average color differences and the luminance signal to generate a correction image signal for the subject, and a selector for outputting the correction image signal the decoder generates when the color misregistration detector determines that color misregistration is present, and outputting a color image signal when the color misregistration detector determines that color misregistration is absent. Herein, the averages of color differences are updated by the color misregistration detector only when color misregistration is not identified.
