Title SOLID STATE IMAGE PICK-UP DEVICE, AND PIXEL
Abstract

In the present invention, a pixel (10) comprises the following: a photodiode (PD) provided between a first barrier region (21) that forms a first potential barrier (B1) and a second barrier region (27) that forms a second potential barrier (B2)

a first floating diffusion region (F1) provided in close proximity to the first barrier region (21) and to which a first charge generated in the photodiode (PD) is transmitted

and a second floating diffusion region (F2) provided in close proximity to the second barrier region (27) and into which a second charge generated in a photoelectric conversion region (PD) flows and that stores a portion of the second charge which flowed thereinto. The second potential barrier (B2) is lower than the first potential barrier (B1).
