Abstract
According to one embodiment, a photoelectric conversion device comprises: a pixel array including a plurality of pixels arranged in a matrix form, the plurality of pixels including an effective pixel that outputs a signal corresponding to incident light and a light-shielded pixel having a light-shielding member; a calculation unit that calculates a correction value based on a pixel value of the light-shielded pixel; and a correction unit that corrects a pixel value of the effective pixel based on the correction value, wherein a pixel row of the pixel array includes a first light-shielded pixel, a second light-shielded pixel, and the effective pixel, and wherein the calculation unit calculates the correction value using different parameters for each of the first light-shielded pixel and the second light-shielded pixel in the pixel row.
