Abstract
Provided are a device for detecting chemical and physical phenomenon suitable for high integration, and a method therefor. Rather than using a TG section signal to select pixels that require charge measurement, the on-off timing (the timing for moving the charge from a sensing section to an FD section) of the TG section is harmonized for all pixels, and the release or injection of the charge to the sensing section is separately controlled, whereby the charge is held only in sensing sections of pixels that require charge measurement, and the charge is emptied in sensing sections of pixels that do not require charge measurement. In this state, the TG section of all pixels can be opened at the same time, whereby the charge is transferred to the FD section from only the sensing sections holding a charge, and the charge level of the pixel is detected.
