Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/054230
Kind Code:
A1
Abstract:
[Problem] Conventional CMOS image sensors have a problem in that when signal charge of a light reception unit is added to an addition accumulation unit a plurality of times, output that is directly linearly proportional to the number of times of addition cannot be obtained. [Solution] An imaging device in which arranged are pixels each having: a light reception unit; a unit accumulation unit for accumulating a part or whole of signal charge of the light reception unit; a reading transistor disposed between the light reception unit and the unit accumulation unit; an adding accumulation unit for adding a part or whole of signal charge of the unit accumulation unit; an adding transistor disposed between the unit accumulation unit and the addition accumulation unit; and a source follower amplifier (AMP) in which a floating diffusion (FD) is disposed, wherein the unit accumulation unit is disposed between the light reception unit and the FD.
