Patent ID: 7710479

Claim:
A solid-state image pickup device comprising: a pixel array unit including unit pixels which are two-dimensionally arranged in a matrix pattern, each unit pixel including a photoelectric converter, and column signal lines corresponding to respective columns of the matrix pattern; row scanning means for selectively controlling each unit pixel of the pixel array unit in units of rows; analog-digital converting means for converting analog signals output from the unit pixels in a row selectively-controlled by the row scanning means through the column signal lines to digital signals, adding the obtained digital signals among a plurality of unit pixels, and outputting the added digital signals; column scanning means for controlling output of the digital signals added in the analog-digital converting means; and an output line for transmitting the digital signals output from the analog-digital converting means under control by the column scanning means, wherein the row scanning means comprises an address decoder which selectively controls each unit pixel of the pixel array unit in units of arbitrary rows.
