    摘要： In an image sensing apparatus, an array of two-dimensional matrix of photosensitive devices is used to detect an image. Each photosensitive device comprises a photosensor accumulating carriers when exposed to a light, control terminals, and an output terminal. A signal generator supplies a vector or a one-dimensional data to the control terminals in the array to output pixel data of the two-dimensional matrix, and the pixel signal is output through the output terminal. The control terminals of the photosensors arranged along each line are connected commonly, while the output terminals thereof arranged along each column are connected commonly. A controller supplies control signals to the control terminals. Then, pixel signal for columns designated by a control signal are output through an output circuit connected to the control terminals. Then, a partial region in the array including a region exposed by the light is determined according to the pixel signals, and data on the partial region is sent to the controller. Then, the controller supplies control signals in correspondence to the partial region. Then, correlation operation of the control signals with the amount of carriers in the photosensors are carried out while reading the pixel signals, and the pixel signals in the partial region is output.

    摘要： Provided is a solid-state imaging element including pixel signal read lines, and a pixel signal reading unit for reading pixel signals from a pixel unit via the pixel signal read line. The pixel unit includes a plurality of pixels arranged in a matrix form, each pixel including a photoelectric conversion element. In the pixel unit, a shared pixel in which an output node is shared among a plurality of pixels is formed, and a pixel signal of each pixel in the shared pixel is capable of being selectively output from the shared output node to a corresponding one of the pixel signal read lines. The pixel signal reading unit sets a bias voltage for a load element which is connected to the pixel signal read line and in which current dependent on a bias voltage flows in the load element, to a voltage causing a current value to be higher than current upon a reference bias voltage when there is no difference between added charge amounts, when addition of pixel signals of the respective pixels in the shared pixel is driven.

    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.
