Title:
IMAGE CAPTURING DEVICE AND ENDOSCOPIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/205507
Kind Code:
A1
Abstract:
An image capturing device according to the present invention comprises a voltage generating circuit and an output circuit. The voltage generating circuit includes a first capacitance element having a fifth terminal. The voltage generating circuit applies, to the fifth terminal, a first voltage depending on a power supply voltage, thereby accumulating a charge in the first capacitance element. The voltage generating circuit increases the voltage at the fifth terminal by a second voltage depending on the power supply voltage, thereby generating a control voltage having an absolute value greater than the absolute value of the power supply voltage. The output circuit outputs the control voltage to at least one of the gate terminal of a reset transistor of a pixel and the gate terminal of a transfer transistor of the pixel.
