IMAGING ELEMENT, IMAGING DEVICE, ENDOSCOPE AND ENDOSCOPE SYSTEM

摘要

An imaging element which enables reduction in power consumption and miniaturization in chip size, an imaging device, an endoscope and an endoscope system are provided. The imaging element is provided with: a sample-and-hold unit 262 which holds and outputs and imaging signal transferred from a horizontal transfer line 258; a reference voltage generation unit 246 which generates and outputs a reference voltage corresponding to a prescribed voltage; an amplifier unit 263 which is connected to the sample-and-hold unit 262 and the reference voltage generation unit 246 and which amplifies and outputs a signal inputted from the sample-and-hold unit 262 with the reference voltage Vref as a reference; and a timing generation unit 25 which controls the voltage of the reference voltage Vref inputted to the amplifier unit 263 during the horizontal blanking intervals and/or the image signal intervals of the imaging signal.
