PROBLEM TO BE SOLVED: To provide a pixel structure which can enlarge a dynamic range without enlarging a pixel area.SOLUTION: An imaging apparatus includes: a photoelectric conversion section for photoelectrically converting incident light; a charge accumulation region for accumulating at least a part of a signal charge generated in the photoelectric conversion section apart from the photoelectric conversion section; a first transfer section for transferring an electric charge in the charge accumulation region to a floating diffusion region; a second transfer section for transferring the signal charge to the charge accumulation region from the photoelectric conversion section; and an amplification section for amplifying a signal depending on the signal charge transferred to the floating diffusion region. The imaging apparatus also includes an imaging region including a plurality of pixels. A plurality of charge accumulation regions are arranged for one photoelectric conversion section.SELECTED DRAWING: Figure 4 |
