There is included: a light receiving device configured to receive light and convert the received light into a light detection signal; a pixel transistor connected to the light receiving device and configured to control connection between the light receiving device and a signal line; a low-pass filter configured to be applied with respect to the light detection signal; an A-D converter configured to convert an output signal of the low-pass filter into digital data; and a sequencer configured to, prior to causing the A-D converter to operate to output the digital data, control the pixel transistor to be in an ON state and thereby maintain the light receiving device to be connected to the signal line, in a state in which the low-pass filter is caused to function effectively with respect to the light detection signal.

Imaging unit and imaging method

A display device with a touch detection function includes a display function layer, a plurality of touch detection electrodes arranged side by side to extend in a first direction, and a plurality of drive electrodes arranged side by side to extend in a second direction, electrostatic capacitance being formed at intersections of the touch detection electrodes and the drive electrodes. The plurality of drive electrodes extends to a first position or a second position outside of the first position, the first position being away from a center of an outermost touch detection electrode by a half length of an arrangement pitch of the touch detection electrodes, the outermost touch detection electrode being defined as outermost one of touch detection electrodes included in an effective display region of the display function layer, and an outer edge of the effective display region is located on or inside the first position.

Display device with touch detection function and electronic unit

An image pickup unit includes: a signal generating section generating a pulse signal that makes transitions between a first voltage and a low-noise second voltage; a voltage holding section holding a difference between a voltage of the pulse signal and a voltage of an output node; a voltage setting section that generates a pixel selection signal through setting the voltage of the output node to a third voltage in correspondence to a transition of the pulse signal from the second voltage to the first voltage, and outputs the pixel selection signal from the output node; and an image pickup section driven by the pixel selection signal.

Image pickup unit, method of driving image pickup unit, and image pickup display system

An image pickup unit includes: an image pickup section including a plurality of pixels, each of the pixels including a photoelectric conversion device; and a drive section driving each of the pixels to perform a readout operation, a pre-reset operation, and a main reset operation in this order, the readout operation being intended to read out charge from each of the pixels as a signal, the charge being obtained from the photoelectric conversion device, and the pre-reset operation and the main reset operation being intended to reset the charge in the each of the pixels. The drive section applies a voltage to the photoelectric conversion device, the voltage being different between in the pre-reset operation and in the main reset operation.

Image pickup unit and image pickup display system

An image pickup unit includes: an image pickup section including a plurality of pixels, each of the pixels including a photoelectric conversion device; and a driving section that includes an amplifier and drives each of the pixels to perform a read out operation intended to read out electric charge obtained by the photoelectric conversion device from the pixel as a signal with use of the amplifier, a pixel reset operation intended to reset electric charge in the pixel, and an amplifier reset operation intended to reset an operation of the amplifier. The driving section drives each of the pixels to allow one or both of end timing of the pixel reset operation and end timing of the amplifier reset operation not to be included in a predetermined power-source potential unstable period.
