Abstract
An object being frame-sequentially illuminated by beams of illumination light in different wavelength ranges is imaged by an imaging element of an electronic endoscope. A time-serial image signal is subjected to signal processing to display a color picture on a monitor screen. A relative movement between the object and the imaging element is detected by a movement detecting circuit to reduce color smear produced by the relative movement in a motion picture of the object displayed on the monitor screen.
