Abstract: An endoscope includes: a CMOS image sensor including only a vertical OB pixel region as an optical black pixel region, and a horizontal OB pixel region generation processing section that reads a photoelectric conversion signal generated in an effective pixel region in the CMOS image sensor and an OB signal generated in the vertical OB pixel region, adds the OB signal generated in the vertical OB pixel region to the beginning or end of each row of the photoelectric conversion signal which has been generated in the effective pixel region and read out for each row, and outputs a signal to which the OB signal is added.

Abstract: An imaging device includes: an imaging element that generates an image signal of a subject; an observation method determining unit that determines, based on identification information indicating types of a control device connected to the imaging device, whether the control device adopts a first observation method for processing an image signal indicating a plurality of images of the subject per one frame period or a second observation method for processing an image signal indicating a single image of the subject per one frame period; and a data reducing unit. If the control device adopts the second observation method, the data reducing unit reduces a data amount of the image signal to be transmitted to the control device per unit time such that a transmission rate indicating the data amount of the image signal per unit time is acceptable to the control device that adopts the second observation method.
