摘要： Provided is an imaging apparatus including a pixel array in which a plurality of pixels are arranged in a matrix, each of the pixels comprising a photoelectric conversion portion. The pixel array includes a first pixel configured to output an imaging signal in accordance with an incident light and a second pixel configured to output a correction signal used for correcting the imaging signal. The second pixel outputs the correction signal after performing a first reset performed in a state where a first bias voltage is applied to the photoelectric conversion portion of the second pixel and a second reset performed in a state where a second bias voltage that is different from the first bias voltage is applied to the photoelectric conversion portion.

摘要： A photoelectric conversion device includes a plurality of pixels. Each pixel includes an amplification transistor that has an input node configured to receive electric charge generated through photoelectric conversion, a reset transistor, and a capacitance control unit. In a state where the reset transistor is off, the capacitance control unit switches a capacitance of the input node from a first capacitance value to a second capacitance value, which is greater than the first capacitance value. Subsequently, the reset transistor is controlled from off to on in a state where the capacitance of the input node has been controlled to the second capacitance value. After the reset operation, the amplification transistor outputs a pixel signal in a state where the capacitance of the input node is the first capacitance value.

摘要： Provided is an imaging device including a pixel array including pixels; a readout circuit that reads out signals from the pixels; a temperature sensor that outputs a signal in accordance with a temperature; and a current control circuit that controls a current supplied to the temperature sensor. The current control circuit performs control in a first period such that a predetermined current is supplied to the temperature sensor, and performs control in a second period such that a current supplied to the temperature sensor becomes smaller than the predetermined current or stops. The first period is set in a first blanking period between a process in which the first readout circuit reads out one frame of signals output from the pixels and a process in which the first readout circuit reads out next one frame of signals output from the pixels.

摘要： A semiconductor apparatus includes a semiconductor device that performs signal processing, a driving control unit that controls drive of the semiconductor device, and a lifetime obtaining unit that obtains remaining lifetime information that represents a remaining lifetime of the semiconductor device. In a case where the remaining lifetime information represents a first length, the driving control unit drives the semiconductor device in a first condition. In a case where the remaining lifetime information represents a second length shorter than the first length, the driving control unit drives the semiconductor device in a second condition in which throughput of the signal processing is lower than that in a case where the semiconductor device is driven in the first condition, and the remaining lifetime of the semiconductor device is longer than that in the case where the semiconductor device is driven in the first condition.
