    Abstract: A CMOS sensor has unit pixels each structured by a light receiving element and three transistors, to prevent against the phenomenon of saturation shading and the reduction of dynamic range. The transition time (fall time), in switching off the voltage on a drain line shared in all pixels, is given longer than the transition time in turning of any of the reset line and the transfer line. For this reason, the transistor constituting a DRN drive buffer is made proper in its W/L ratio. Meanwhile, a control resistance or current source is inserted on a line to the GND, to make proper the operation current during driving. This reduces saturation shading amount. By making a reset transistor in a depression type, the leak current to a floating diffusion is suppressed to broaden the dynamic range.

    Abstract: A solid-state imaging device includes: a pixel section wherein pixels including photoelectric conversion devices are arranged in a matrix; and a pixel driving section including a row selection circuit which controls the pixels to perform an electronic shutter operation and readout of the pixel section. The row selection circuit has a function of selecting a readout row from which a signal is read out and a shutter row on which reset is performed by discharging charge accumulated in the photoelectric conversion devices, in accordance with address and control signals. The row selection circuit can set, in accordance with the address and control signals, in the pixels of the selected row, at least a readout state, a discharge state where a smaller amount of the charge accumulated in the photoelectric conversion devices than the reset is discharged, an electronic shutter state, and a charge state where the charge is accumulated in the photoelectric conversion devices.

Each of a plurality of pixel units includes a pixel and a reset transistor, and the pixel includes a photoelectric converting unit that performs photoelectric conversion on light of a certain color incident through a color filter and a transfer transistor that transfers charges obtained by the photoelectric conversion of the photoelectric converting unit and is controllable for each color. According to control of the transfer transistor, the charges are read from the photoelectric converting unit through the transfer transistor and the reset transistor, and a voltage corresponding to the charges is supplied to an AD converting unit connected to the reset transistor. The present technology can be applied to, for example, an image sensor that photographs an image.

    Abstract: An image sensor architecture with multi-bit sampling is implemented within an image sensor system. A pixel signal produced in response to light incident upon a photosensitive element is converted to a multiple-bit digital value representative of the pixel signal. If the pixel signal exceeds a sampling threshold, the photosensitive element is reset. During an image capture period, digital values associated with pixel signals that exceed a sampling threshold are accumulated into image data.
