摘要： A solid-state imaging apparatus comprises a plurality of matrix pixels, a reference signal generator for generating a ramp signal, a counter for performing counting according to the ramp signal output, and an AD converter, arranged for each pixel column, for performing AD conversion by comparing a pixel signal from the pixel with the ramp signal. Further, the AD converter includes a comparator to which the pixel signal and the reference signal are input, a storage for storing the AD conversion result, and an slope converter, between the output terminal of the reference signal generator and the input terminal of the comparator, for changing a gradient of the ramp signal, so that the noise overlaid on the ramp signal changes depending on the gradient of the ramp signal. Thus, it is possible to prevent generation of a horizontal-line noise in the ramp signal.

摘要： An imaging system (90, 490, 590, 690) includes an image sensor (100, 400, 500, 600) and a mechanical shutter (93) which controls the termination of exposure of the image sensor. The image sensor includes a pixel array (PA) in which a plurality of pixels are arrayed in a matrix, and a vertical scanning unit (220, 420, 520, 620) which scans the pixel array for each row. The vertical scanning unit parallelly executes some of the reset operations of pixels on at least two adjacent rows of the pixel array. The charge accumulation operation of pixels starts upon completion of the reset operation and terminates in response to light shielding by the mechanical shutter.
