Abstract:
1. An endoscope system, comprising: a solid-state image pickup device for picking up an image of an object, to output an image signal; an illuminator for applying a normal light and a specific light having a wavelength range different from said normal light to said object; a motion detector for detecting information of a relative motion of said object by comparing image signals of two frame images output from said solid-state image pickup device; a controller for controlling said illuminator, for causing alternate emission of said normal and specific light periodically at a storage period of said image pickup device if said detected motion information of the relative motion of said object is equal to or smaller than a threshold level, and for causing emission of said normal light without emitting said specific light if said detected motion information of the relative motion of said object is greater than said threshold level; a display control unit for causing display of a normal image produced from said image signal in applying said normal light, and additionally a specific image produced from said image signal in applying said specific light, wherein, if said detected motion information is greater than said threshold level, then said display control unit causes a display of a motion picture of said normal image, and a still picture of said specific image under a condition of said controller shortly before turning off said specific light, in a form arranged together.
