Abstract:
An image pixel includes light nodes and a dark node. The dark node includes: a first charge storage unit for storing first power supply information during a first time period; a second charge storage unit for storing second power supply information related to the power supply during a second time period; and an information output unit for outputting a first sample signal related to the first power supply information or a second sample signal related to the second power supply information. The first power supply information remains in the first charge storage unit during the second time period and during when the second sample signal is outputted by the information output unit.
