摘要： A CMOS image sensor includes column-parallel ADCs. Each of the ADCs includes a comparator and an up/down counter. With this configuration, digital values of pixels in a plurality of rows can be added without using additional circuits, such as an adder and a line memory device, and the frame rate can be increased while maintaining constant sensitivity.

摘要： A DA conversion device includes the following elements. A higher-bit current source cell portion includes uniformly weighted higher-bit current source cells to generate an identical constant current. A lower-bit current source cell portion includes a lower-bit current source cells that are weighted to generate 1/two-to-the-power-of-certain-numbers constant currents. A constant current source selection controller includes a lower-bit controller having a scaler that uses clocks scaled down to 1/two-to-the-power-of-certain-numbers to select the lower-bit current source cells, and a higher-bit controller having shift registers and using a signal indicating a carry bit or a borrow bit used in the lower-bit controller to sequentially activate shift outputs of the shift registers, and uses the shift outputs to select the higher-bit current source cells. Constant current outputs of the selected current source cells are added and output so that an output current corresponding to the digital input signal is obtained.

摘要： In a solid-state imaging device meeting color image pickup, which an AD converter is mounted on the same chip, the circuit scale and the number of transmission signal lines are reduced and a reference signal suitable for color image pickup is fed to an AD conversion comparing portion. DA converter circuits for two pixels of a repeat unit of a separation filter in the horizontal row direction in a unit of readout are prepared as a functional portion to generate a reference signal for AD conversion. The DA converter circuits generate the reference signals having a tilt in accordance with a color property and varying from an initial value based on a non-color property such as a black reference and a circuit offset. Each reference signal independently outputted from the DA converter circuits is basically directly transmitted through common signal lines to a voltage comparing portion which corresponds to color filters having a common color property through independent signal lines.
