Abstract:
1. An image sensing apparatus comprising: a pixel array in which a plurality of pixels including a first pixel and a second pixel are arrayed; a readout unit that reads out a signal from the pixel array and outputs a plurality of signals; and an output unit including: a first output line that transmits an optical signal of the first pixel, that is output from the readout unit, wherein the optical signal of the first pixel is a signal in which a noise signal of the first pixel is superimposed on an image signal of the first pixel, a second output line that transmits the noise signal of the first pixel, that is output from the readout unit, a third output line that transmits an optical signal of the second pixel, that is output from the readout unit, wherein the optical signal of the second pixel is a signal in which a noise signal of the second pixel is superimposed on an image signal of the second pixel, a fourth output line that transmits the noise signal of the second pixel that is output from the readout unit, a first difference circuit that operates a difference between the optical signal of the first pixel and the noise signal of the first pixel to generate a first image signal, and a second difference circuit that operates a difference between the optical signal of the second pixel and the second signal of the second pixel to generate a second image signal, wherein the first output line is arranged between the third output line and the fourth output line, and wherein the third output line is arranged between the first output line and the second output line.
