ABSTRACT:
An image processing method for use in an electronic video endoscopy system in which R, G and B surface sequential color signals are obtained from a CCD disposed in the leading end portion of an endoscope. The surface sequential color signals are converted simultaneously wherein memories corresponding to the respective colors are used to thereby obtain synchronous color signals. In the image processing method, the odd and even fields of the CCD are interline transferred sequentially within one field period to thereby obtain the above-mentioned surface sequential color signals, and data for each of horizontal scanning lines are read out alternately from odd and even field data once stored in the above-mentioned respective memories to thereby complete frame data so as to obtain the above-mentioned synchronous color signals.
