Zusammenfassung:An image sensor may include image pixels arranged in rows and columns. The image pixels may include an anti-blooming transistor controlled by a first control signal and a transfer transistor controlled by a second control signal. The first and second control signals are generated based on different sets of phases. The different sets of phases are offset from each other. By having a delayed or offset set of phases, the first and second control signals may be asserted independently from each other thereby providing shorter integration time periods during a light flicker mitigation mode of operation. An additional set of phases may be added before readout operations to account for the delay and ensure proper readout operations.
