ABSTRACT:
In order to solve the problem in which voltages Vsig1 read in units of rows have differences to cause vertical shading, thereby degrading image quality, and the problem in which the dynamic ranges of source follower circuits are different in units of rows because finite resistances are distributed in the power supply lines, a photoelectric conversion apparatus includes photoelectric conversion portions placed in a plurality of rows, an amplification section including a load section arranged in units of vertical output lines to amplify signal charges accumulated in the photoelectric conversion portions placed in a plurality of rows, a vertical scanning section for sequentially scanning signals amplified by the amplification section to read the signals onto the vertical output lines, and a horizontal scanning section for sequentially scanning the signals amplified by the amplification section to read the signals onto horizontal output lines, wherein the load sections are located on a side vertically opposite to the direction of signal output from the amplification section.
