SOLID-STATE IMAGING DEVICE, OPTICAL SENSOR, AND SOLID-STATE IMAGING DEVICE OPERATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a solid-sate imaging device and an optical sensor which can have a wide dynamic range while maintaining a high sensitivity and a high S/N ratio, and a solid-state device operation method for having a wide dynamic range while maintaining the high sensitivity and the high S/N ratio. SOLUTION: Each of the pixels has a photodiode PD for receiving light and generating an accumulating photoelectric charge, and an accumulation capacity element CSfor accumulating the photoelectric charge flowing out from the photodiode which are connected via a transfer transistor Tr1. The pixels are accumulated in an array shape. Here, the accumulation capacity element CShas a configuration for accumulating the photoelectric charge flowing out from the photodiode PD in an accumulation capacity element accumulation period TCSset with a predetermined period ratio from the accumulation period of the photodiode PD.
