摘要： An imaging system comprises an image sensing apparatus including a pixel array, a row selection unit, and a readout unit; and a supply unit including a plurality of A/D converting units, and a transfer unit. The supply unit supplies a power supply voltage to an A/D converting unit which, of the plurality of A/D converting units, receives signals from the pixels in the pixel array by means of the transfer unit, and does not supply a power supply voltage to an A/D converting unit which, of the plurality of A/D converting units, receives no signals from the pixels in the pixel array by means of the transfer unit, in a 1-line period. The readout unit A/D-converts the signals from the pixels in the pixel array using the A/D converting unit supplied with the power supply voltage by the supply unit, and outputs a digital image signal.

摘要： A system and method for driving a solid-state image pickup device including a pixel array unit including unit pixels. Each unit pixel includes a photoelectric converter, column signal lines and a number of analog-digital converting units. The unit pixels are selectively controlled in units of rows. Analog signals output from the unit pixels in a row selected by the selective control though the column signal lines are converted to digital signals via the analog-digital converting units. The digital signals are added among a number of unit pixels via the analog-digital converting units. The added digital signals from the analog-digital converting units are read. Each unit pixel in the pixel array unit is selectively controlled in units of arbitrary rows, the analog-distal converting units being operable to performing the converting in a (a) normal-frame-rate mode and a (b) high-frame-rate mode in response to control signals.

摘要： The present invention is directed to an apparatus, method and software product for enhancing the dynamic range of a CCD sensor without substantially increasing the noise. Initially, the area of a N×M pixel CCD sensor array is subdivided into two regions, a large region having (M−a) pixels in each column for outputting large-amplitude signals with low noise and a smaller region having a pixels in each column for outputting small-amplitude signals with improved dynamic range. At integration time, the CCD is read out one region's rows at a time into the horizontal shift registers by shifting the pixel charges in either a or M−a vertical shifts. The charges in the horizontal shift registers are then shifted out of the horizontal shift registers in N horizontal shifts. Next, the remaining pixels in the region of the CCD are read out into the horizontal shift registers by shifting the pixel charges in the other of a or M−a vertical shifts. Those charges are then shifted out of the horizontal shift registers in N horizontal shifts. In a spectrographic application, the data from the two regions is read out in the form of a large-amplitude channel from the larger region's rows and a small-amplitude channel from the smaller region's rows.

The imaging unit outputs image signals of red and blue and an image signal of green of which sample phases in a space are shifted by one pixel interval in a vertical direction using the two-line addition function. A resolution conversion unit obtains image signals of red, green, and blue of which the number of lines is doubled by performing interpolation processing on the image signals of red and blue and an image signal of green output from the imaging unit.
