Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/157086
Kind Code:
A1
Abstract:
This imaging device (1) is equipped with multiple pixel circuits (3), pixel amplifiers (5), and a control circuit (7). Each pixel circuit (3) has a light-receiving section (13), a charge-draining section (15), a temporary accumulation section (15a) that is provided on an end side of the charge-draining section (15), multiple transfer gates (17) that are arranged so as to surround the temporary accumulation section (15a), and multiple charge detection sections (19) that are arranged on the temporary accumulation section (15a) across the transfer gates (17). Each pixel amplifier (5) includes a gain amplifier (25) and a sample-and-hold circuit (27) for each of the multiple charge detection sections (19). The control circuit (7) performs control such that reset operations, charge accumulation operations, and charge readout operations are executed in a pipelined manner for pixel circuits (3), and amplification operations, sample-and-hold operations, and signal read operations for outputting signals to the outside are executed in a pipelined manner for gain amplifiers (25) and sample-and-hold circuits (27).
