摘要：
A solid state image sensor and an image sensing apparatus incorporated with the solid state image sensor include: pixel arrays each provided with pixels, and an accumulating section e.g. a capacitor CX which sums up and accumulates signal charges obtained by exposure of an object with respect to a corresponding color at different timings when the signal charges are obtained by the pixels of each of the pixel arrays. A reset noise of a converting floating diffusion is outputted after the converting floating diffusion is reset. Thereafter, a summation of the reset noise, and the signal charges accumulated in the accumulating section is outputted.
