Solid-state imaging apparatus, and imaging system using the same

A solid-state imaging apparatus comprising:

• plural pixels which include a photoelectric conversion unit for photoelectrically converting incident light into charges corresponding to an amount of the incident light and then accumulating the converted charges and a transfer unit for transferring the charges photoelectrically converted by the photoelectric conversion unit, and are arranged two-dimensionally;
• an impurity diffused region which accumulates the charges transferred from the photoelectric conversion unit through the transfer unit;
• an amplifying unit which outputs signals on the basis of the charges accumulated by the impurity diffused region;
• and
• a reset unit which resets potential of the impurity diffused region,
• wherein the four pixels which include the two pixels adjacent in an oblique direction and the two pixels, in a same row or a same column, adjacent to one of the two pixels adjacent in the oblique direction constitute a unit pixel group, and
• the impurity diffused region, the amplifying unit and the reset unit are commonly connected to the four pixels which constitute the unit pixel group.
