    摘要: An imaging device that includes pixels arranged in a matrix having rows and columns, the pixels including first pixels and second pixels different from the first pixels, the first pixels and the second pixels being located in one of the columns, each of the pixels including a photoelectric converter that converts incident light into signal charge, and a first transistor having a first gate, a first source and a first drain, the first gate being coupled to the photoelectric converter. The imaging device further includes a first line coupled to one of the first source and drain of the first pixels; a second line coupled to one of the first source and drain of the second pixels; a third line coupled to the other of the first source and drain of the first pixels; and voltage circuitry coupled to the third line and that supplies a first and second voltage.

    摘要: An imaging device comprising: a first pixel cell including a first photoelectric converter generating a first signal, the first photoelectric converter including a first electrode and a first photoelectric conversion region on the first electrode, and a first circuit coupled to the first electrode and detecting the first signal; and a second pixel cell including a second photoelectric converter generating a second signal, the second photoelectric converter including a second electrode and a second photoelectric conversion region on the second electrode, and a second circuit coupled to the second electrode and detecting the second signal. A sensitivity of the first pixel cell is higher than that of the second pixel cell. A circuit configuration of the first circuit is different from that of the second circuit. The first circuit includes a feedback circuit configured to negatively feed back a voltage of the first electrode to the first electrode.

    摘要: An imaging device including: a photoelectric converter including first and second electrodes and a photoelectric conversion layer therebetween; a voltage supplier; an output circuit for outputting a signal corresponding to the potential of the second electrode; and a detector for detecting the signal level. The change rate of the conversion efficiency of the photoelectric converter with respect to a bias voltage applied between the electrodes when the bias voltage is in a first range is greater than that when the bias voltage is in a second range higher than the first range. The voltage supplier, when the detected level is a first threshold or higher, causes the potential difference between the electrodes to be a first difference, and, when the detected level is lower than a second threshold that is the first threshold or lower, causes the potential difference to be a second difference greater than the first difference.
