Active pixel sensor circuit, driving method and image sensor
The present disclosure provides an active pixel sensor circuit, a driving method, and an image sensor. The active pixel sensor circuit comprises a photosensitive device, a first storage capacitor, a second storage capacitor and a source follower transistor. The active pixel sensor circuit further comprises a reset sub-circuit, a charging control sub-circuit, a compensation control sub-circuit, a signal-reading control sub-circuit. The charging control sub-circuit controls a second pole of the photosensitive device to be connected to a second terminal of the second storage capacitor during the reset phase and the charging phase, and controls the gate of the source follower transistor to be connected to a second pole of the source follower transistor during the charging phase. The compensation control sub-circuit controls the second terminal of the second storage capacitor to be connected to a second terminal of the first storage capacitor during the reset phase and the compensation phase.
