Title:
SOLID-STATE IMAGING DEVICE AND DISTANCE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/024710
Kind Code:
A1
Abstract:
A solid-state imaging device including a plurality of pixel circuits (1) arranged in a matrix, wherein: the pixel circuits (1) each comprise a photodiode (APD), a first charge storage unit (C1) for storing a charge, a floating diffusion region (FD) for storing a charge, a second charge storage unit (C2) for storing a charge, a first transfer transistor (2) for transferring a charge from the photodiode (APD) to the first charge storage unit (C1), a second transfer transistor (3) for transferring a charge from the first charge storage unit (C1) to the floating diffusion region (FD), a first reset transistor (4) for resetting the floating diffusion region (FD), and an integration transistor (7) for integrating the charge of the floating diffusion region (FD) into the second charge storage unit (C2); the capacity of the first charge storage unit (C1) is larger than the capacity of the floating diffusion region (FD); and the capacity of the second charge storage unit (C2) is larger than the capacity of the floating diffusion region (FD).
