IMAGE PICKUP UNIT FOR ENDOSCOPE AND ENDOSCOPE

摘要

In this invention, an image pickup unit for endoscope including an image pickup device includes, in an optical black region of the image pickup device, a phase reference pixel region in which a pixel that outputs a signal capable of being used for phase adjustment of the video by receiving light is disposed, and an optical axis of an objective optical system member having an image circle which is narrower than an effective pixel region of the image pickup device is arranged at a position closer to the phase reference pixel region with respect to a center of the effective pixel region such that light transmitted through the objective optical system member can reach the phase reference pixel region.
