PROBLEM TO BE SOLVED: To obtain a still picture, etc., in which blue in the direction of depth is eliminated by displaying the expanded image of different depths of fields and the same magnification concerning a matter to be observed catched by variable power operation. SOLUTION: In the electronic endoscope apparatus provided with an optical variable power mechanism and an electronic variable power function, when the first stage of a freeze switch 18 is operated in the state of being magnified optically by A folds, e.g. a magnified still picture at this time is displayed and a lens for variable power is driven at lens positions<a> B,<a> C, and<a> D which become three depths, etc., for comparing observation set in advance. A picture formed by this is given electronic variable power processing for maintaining the A folds and is displayed as a plurality of still pictures focused in different depth ranges on the pictures divided into four pictures of a monitor 31. The plurality of these pictures can be recorded by the operation of the second stages of the freeze switch 18 when selecting one of them with a picture selection switch 36.
