Abstract
An apparatus includes a plurality of pixels each including a charge storage part, a photoelectric conversion part, a first transfer part and a second transfer part, when a signal charge generated during one period is transferred to an amplifier, a control unit supplies pulses such that a turning-on pulse is supplied to the second transfer part while supplying a turning-off pulse to the first transfer part thereby transferring the stored signal charge to the amplifier, a turning-on pulse is then supplied to a reset part to reset the signal charge transferred to the amplifier, and subsequently a turning-on pulse is supplied to the first transfer part and the second transfer part to transfer the signal charge held in the photoelectric conversion part to the amplifier.
Claims7
An apparatus comprising:
- a plurality of pixels, each pixel including a photoelectric conversion part, a charge storage part configured to store a signal charge transferred by a first transfer part from the photoelectric conversion part, an amplifier configured to amplify a signal based on the signal charge transferred by a second transfer part, and a reset part;
- and
- a control unit configured to supply driving pulses, wherein when a signal charge generated during one period is transferred to the amplifier, the control unit supplies pulses such that a turning-on pulse is supplied to the second transfer part while supplying a turning-off pulse to the first transfer part thereby transferring the stored signal charge to the amplifier, a turning-on pulse is then supplied to the reset part to reset the signal charge transferred to the amplifier, and subsequently a turning-on pulse is supplied to the first transfer part and the second transfer part to transfer the signal charge held in the photoelectric conversion part to the amplifier.
