1. An imaging device comprising:
a plurality of pixels arranged in a matrix of rows and columns; and
a signal processing circuit,
the plurality of pixels including:
a plurality of first pixels that each output a pixel signal corresponding to incident light; and
a plurality of second pixels which are aligned in the column direction in at least two columns and which each output a reset signal corresponding to the output signal at reset of each of the plurality of first pixels, the plurality of second pixels being arranged in different columns from the plurality of first pixels, wherein
the signal processing circuit performs AD conversion of a difference signal between the pixel signal outputted by one first pixel from among the plurality of first pixels and a reference signal based on the reset signals outputted by at least two second pixels, from among the plurality of second pixels, located in the same row as the one first pixel.
