Endoscope apparatus

An endoscope apparatus comprising:

• an image pickup unit comprising a plurality of image pickup devices and an optical path dividing member for dividing a light beam entering from an objective lens into a plurality of optical paths and leading the optical paths to the respective plurality of image pickup devices, wherein optical path lengths of the plurality of optical paths are different from one another;
• a contrast comparing member for comparing contrasts of a plurality of images based on a plurality of image signals outputted from the plurality of image pickup devices, respectively;
• an image selecting member for selecting and outputting only an image signal from one image pickup device among the plurality of image pickup devices, on a basis of a result of the comparison by the contrast comparing member;
• and
• a driving member for moving a movable lens so that a difference among the contrasts of the plurality of images based on the plurality of image signals outputted from the plurality of image pickup devices, respectively, is largest, wherein a part of the objective lens is configured to be movable in an optical axis direction as the movable lens.
