Abstract
The present application relates to an electronic endoscope apparatus for forming a preferable static image by controlling blurring of an image at the time of picking up the image by using a variable-power mechanism. This endoscope emits stroboscopic light by a stroboscopic light emission circuit when a freeze button is pressed and sets a high shutter speed shorter than an exposure time for a dynamic image by an electronic shutter circuit. Moreover, observation distances can be changed by moving a movable lens through a variable-power motor section and a linear transmission member in accordance with operation of a variable-power switch. Therefore, a static image is formed trough short-time image pickup by strong illumination light and image blurring is eliminated which becomes remarkable in particular when the image is enlarged through variable-power operation.
