  • Patent number: 8605184
    Abstract: A pixel circuit has first, second, and third field effect transistors integrated and connected in series from a photoelectric conversion element to a side of an amplifier circuit. The first and second field effect transistors have gate electrodes to be simultaneously collectively driven. A threshold voltage of the first field effect transistor is set to be higher than that of the second field effect transistor. As the gate electrodes are driven step by step, electrons generated by the photoelectric conversion element and transferred via the first field effect transistor are accumulated in a channel region of the second field effect transistor. The electrons accumulated in the channel region are transferred to an input of the amplifier circuit via the third field effect transistor.

  • Patent number: 8319850
    Abstract: An imaging element includes: a pixel section in which a plurality of pixels each having a photoelectric conversion element are arranged in a matrix; a signal line to which a signal read from the pixels is transmitted; a holding section for holding the read signal during a holding period; a processing section for performing signal processing on the read signal after being held by the holding section; and a control section for controlling supply of the read signal to the holding section. The control section supplies the read signal to the holding section to cause it to hold the read signal during the holding period, and stops supplying the read signal to the holding section to cause the processing section to perform the signal processing on the read signal and to cause a signal to be read from the pixels and output to the signal line after the holding.
