摘要： A noise correction circuit that detects and corrects noise included in an image signal output from an image sensor is provided. The noise correction circuit includes a noise determining unit, a noise removing unit, and a random number adding unit. The noise determining unit is configured to calculate an average value of a signal level in a predetermined range of the image signal output from the image sensor and use the calculated average value to calculate a noise component in a predetermined direction. The noise removing unit is configured to remove noise from the image signal output from the image sensor in response to the noise component determined by the noise determining unit. The random number adding unit is configured to add a random number at a level not determined by quantization of the image signal to the image signal after removal of the noise by the noise removing unit.

摘要： An image sensor includes a two-dimensional array of pixels having multiple column outputs and an output circuit connected to each column output. Each output circuit is configured to operate concurrent sample and read operations. A timing generator outputs a column address sequence that is received by a column decoder that is electrically connected to each output circuit. The timing generator suspends the output of the column address sequence during a sample operation and resumes the output of the column address sequence at the end of the sample operation.

摘要： An image pickup circuit including a plurality of circuit blocks. Each of the plurality of circuit blocks includes a plurality of comparing elements, a single counter, and a plurality of storage units. Each of the comparing elements compares a pixel signal supplied through a vertical signal line connected to vertically aligned pixels in a plurality of pixels arranged in a matrix, and a slope signal whose voltage is changed from an initial voltage at a constant slope. The counter counts an elapsed time since a voltage of the slope signal starts to change from the initial voltage. Each of the storage units stores a count value obtained by the counter in accordance with a comparison result of the comparator, the count value corresponding to an elapsed time until the voltage of the slope signal is changed from the initial voltage to a voltage coinciding with the pixel signal.

摘要： A solid state image sensor capable of preventing image degradation, such as shading and ringing, from occurring in an image portion along the left edge of a screen. The solid state image sensor includes, in addition to a horizontal drive circuit that generates a horizontal drive pulse for driving a horizontal register, a pseudo-horizontal drive circuit that generates a pseudo-horizontal drive pulse successive to the horizontal drive pulse during a horizontal blanking interval. The horizontal drive circuit and pseudo-horizontal drive circuit are connected to a horizontal driver power supply unit, which generates, during the horizontal blanking interval, a current that is equal to a current generated by the horizontal driver power supply unit during an effective interval. This arrangement can prevent any power supply ripples from occurring immediately after the beginning of the effective interval.
