Abstract

A light detecting device includes: one or more switch transistors, a first pixel including a first floating diffusion region coupled to a first photoelectric converter through a first transfer transistor, and a first amplification transistor coupled to the first floating diffusion region, a second pixel including a second floating diffusion region coupled to a second photoelectric converter through a second transfer transistor, and a second amplification transistor coupled to the second floating diffusion region, and a third pixel including a third floating diffusion region coupled to a third photoelectric converter through a third transfer transistor, and a third amplification transistor coupled to the third floating diffusion region. A pixel signal is differentially amplified by the first and third amplification transistors. The first and second floating diffusion regions are selectively connected to each other via one of the one or more switch transistors.
