ABSTRACT:
An electronic endoscope apparatus is provided that comprises an image-pickup device, an objective optical system, a compensation information storing memory, a mask data storing memory, and an electronic mask compensation processor. The objective optical system forms a subject image on an imaging surface of the image-pickup device. The compensation information storing memory stores compensation information which relates to a misalignment between an in-focus area produced by the objective optical system on the imaging surface, and an effective image sensing area of the image-pickup device. The mask data storing memory stores mask data for an electronic mask operation. The electronic mask compensation processor translates an electronic mask area in accordance with the compensation information.
