PROBLEM TO BE SOLVED: To provide high image quality by reducing the influence of dark-current noise even if a dynamic range is expanded under a condition for high-sensitivity shooting. SOLUTION: An imaging device comprises: a photodiode (PD) receiving light, generating electric charges according to the received light, and storing the charges; a floating diffusion (FD) storing electric charges; and an electric charge holding section (MEM) disposed between the PD and the FD. In a first operation mode (step S106), the MEM is connected with the FD by a second transfer switch while charges are stored in the PD, and in a second operation mode (step A107), the MEM is disconnected from the FD by the second transfer switch while charges are stored in the PD. Then, the first and second operation modes are selected according to a shooting condition in shooting a subject (step S105). COPYRIGHT: (C)2011,JPO&INPIT |
