1. An imaging device, comprising:
a plurality of pixels each including a photoelectric conversion element, wherein the plurality of pixels is in an array of matrix, and the photoelectric conversion element is configured to generate a charge;
a control line group including a plurality of control lines for control of each pixel of the plurality of pixels aligned in a row direction, each arranged in each of rows of the array; and
a plurality of reading lines in each of columns of the array for transfer of a pixel signal read from each pixel of the plurality of pixels aligned in a column direction of the array,
wherein the plurality of pixels includes:
a first pixel controlled by a control signal supplied from a first control line group including control lines in a first number among the plurality of control lines in each of the plurality of pixels aligned in the row direction in at least one of the rows of the array; and
a second pixel controlled by a control signal supplied from a second control line group including a control line in a second number smaller than the first number among the plurality of control lines, and
the first pixel includes:
a first accumulation section configured to accumulate the charge, generated by the photoelectric conversion element, based on a control signal from a first control line of the control line group;
a first charge voltage conversion section configured to convert the accumulated charge into a voltage based on a control signal from a second control line of the control line group; and
a first selection section configured to output a pixel signal to a reading line of the plurality of reading lines based on the voltage and a control signal from a third control line of the control line group.
