An image sensor has a plurality of pixels, each pixel including a photoelectric
converter and a pixel circuit for processing signals from the photoelectric converter
and outputting processed signals and a scanning circuit, disposed between the photoelectric
converters, included in each of at least two adjacent pixels among a plurality
of pixels aligned in a single direction. An edge pixel accommodates, in order from
an edge of the image sensor toward an interior, a predetermined empty region, a
photoelectric converter and a pixel circuit. There is at least one position at
which two adjacent pixels, the first of the two pixels accommodating, in order,
a pixel circuit, a photoelectric converter and predetermined empty region, the
second accommodating, in order, a predetermined empty region, a photoelectric converter
and a pixel circuit. The scanning circuit is disposed in the predetermined empty
region between the two adjacent pixels.
