Abstract
An image sensor includes pixel sections corresponding to unit pixels, a column signal line arranged for each column of the pixel sections, a row scanning circuit which selects the pixel sections for each row and transfers an analog signal to the column signal line, a column amplifier which amplifies the analog signal, an A/D converter which converts the analog signal into a digital signal for each column, a column scanning circuit which outputs the signal converted into the digital signal to a horizontal signal line, and a digital adder which adds the digital signals. The column amplifier adds the signals output from the pixel sections to the column signal line. The column scanning circuit outputs digitized signals of a plurality of columns. The digital adder adds the signals of the plurality of columns.
