ABSTRACT:
An electronic endoscope apparatus is of a field-sequential imaging type, comprising an illuminating unit for illuminating an object by sequentially emitting color illumination rays with a plurality of different wavelengths and an imaging device for photoelectrically transforming the object image formed with the color illumination rays emanating from the illuminating unit. The electronic endoscope includes a drive circuit for driving the imaging device so as to read the locations in the imaging device associated with only one of two fields, image memories for storing video signals representing the object image formed with the color illumination rays and having been read from the imaging device, and memory control units for reading color video signals from the image memories in synchronization with a vertical-synchronizing signal.
