Abstract
An endoscope apparatus having an end section provided with an image forming optical system, a self-scanning type solid state image pickup device at which cyan and yellow color filters are positioned alternately to correspond to respective picture elements of the image pickup device, and a light guide. When green light is emitted from the light guide to an object, image signals corresponding to the green component of the object are picked up from all picture elements. When white light is emitted, cyan component image signals are picked up from the picture elements where the cyan filters are positioned, and yellow component signals form those where the yellow filters are positioned. Alternatively, when green light is emitted, green component signals are picked up from all picture elements and, when magenta light is emitted, blue component signals are picked up from the picture elements where the cyan filters are positioned and red component signals are picked up from those where the yellow filters are positioned. The image signals are then electrically processed to form a color image.
