Abstract
A pixel circuit includes a first photocharge accumulator including at least two photodiodes exposed to light for a long period of time, and a second photocharge accumulator including at least one photodiode exposed to light for a short period of time. The pixel circuit includes a first transfer controller that transfers photocharges accumulated in the first photocharge accumulator to a floating diffusion area, and a second transfer controller that transfers photocharges accumulated in the second photocharge accumulator to the floating diffusion area. The pixel circuit includes a driving transistor to generate a pixel signal according to the photocharges transferred to the floating diffusion area. A number of photodiodes of the first photocharge accumulator is greater than a number of photodiodes of the second photocharge accumulator.
