Patent ID: 7924335

Claim:
A solid state imaging device comprising: a pixel array unit where unit pixels each including a photoelectric conversion element are two-dimensionally arrayed in a matrix shape; a row scanner for selecting an arbitrary row in the pixel array unit; a plurality of column-by-column AD converters for separately converting voltage signals respectively outputted from the plurality of unit pixels in the selected arbitrary row into digital signals; a column scanner for sequentially column-scanning the digital signals outputted by the plurality of column-by-column AD converters and outputting them; a controller for timing-controlling the row scanner, the column-by-column AD converters and the column scanner; and an AD conversion result adjuster for judging 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 converting the digital signals into digital pixel values set in accordance with the predetermined judgment value when a result of the judgment is positive.
