IMAGING ELEMENT, IMAGING DEVICE, ENDOSCOPE, ENDOSCOPE SYSTEM, AND METHOD FOR DRIVING IMAGING ELEMENT

摘要

Provided are an image sensor, an imaging device, an endoscope, an endoscope system, and a method for driving the image sensor that are capable of shortening a read time in an OB region. An imaging unit 20 includes a reference signal generation unit 248 that generates and outputs a reference signal in accordance with a predetermined voltage, a plurality of unit pixels 230 that generates and outputs an imaging signal, a vertical scanning unit 241 and a horizontal scanning unit 245 that transfer the reference signal and the imaging signal during different periods, and a buffer 26 that holds the reference signal and the imaging signal separately, sequentially switches between the signals and outputs the switched signal.
