    摘要： A solid state image sensor comprising a matrix of photosensitive elements adapted to accumulate signal charges corresponding to at least two different aspect ratios, a plurality of vertical shift registers disposed adjacent to columns of the photosensitive elements for a vertical transfer of the signal charges and a plurality of horizontal shift registers corresponding to the respective aspect ratios and disposed in parallel with each other for a horizontal transfer of the signal charges from the vertical shift registers. As a horizontal shift register exclusive to each aspect ratio is provided in the above manner, it is no longer necessary to superimpose the signal outputs of a plurality of buffer amplifiers so that a picture signal corresponding to the desired aspect ratio can be easily read out.

    摘要： A driving method is applied to a solid-state imaging apparatus having photoelectric conversion portions, transfer portion for reading out signal charges, and an excess charge draining portion for draining charges exceeding a saturation charge amount that is set by a reference voltage. One of driving modes is selected from a full pixel mode in which accumulated signal charges are detected individually for each pixel and a pixel mixing mode in which signal charges of a predetermined number of pixels are mixed to be detected. In the full pixel mode, the draining portion is supplied with the reference voltage having the same value during a charge accumulation period and a read transfer period for read transferring charges. In the pixel mixing mode, the draining portion is supplied with the reference voltage having a low level during the charge accumulation period and the reference voltage having a high level during the read transfer period. An appropriate driving for the pixel mixing mode can be performed by avoiding a limitation of a substrate voltage, without deteriorating the spectral characteristics, the sensitivity, nor the linearity.

    摘要： A row scanner selects an arbitrary row in an pixel array unit. Per-column AD converters separately convert voltage signals respectively outputted from a column of a plurality of unit pixels in the selected arbitrary row into digital signals. A column scanner sequentially outputs the digital signals by a column-scanning operation thereof. An AD conversion result adjuster judges whether or not the digital signals reach a predetermined judgment value or the status equivalent to the digital signals reaching the predetermined judgment value is generated, and fixes the digital signals to digital pixel values set in accordance with the predetermined judgment value when a result of the judgment is positive.
