In a frame sequentially scanning type color endoscope apparatus, a light chopper is employed in conjunction with a xenon lamp. The light chopper is constructed of a disk, three slots formed in a peripheral portion of the disk, and three different color filters mounted on the corresponding slots. Positions of two slots are juxtaposed with each other with respect to another position of the remaining slot. Three different color light pulses are produced from three color filters with having the substantially same duration times and different time intervals.
