Title: Imaging apparatus configured to correct noise

Abstract: An imaging apparatus includes an imaging area having, in a vertical direction, a plurality of lines having a plurality of pixels in a horizontal direction, wherein each of the plurality of lines includes an light-shielded area and an effective pixel area that is not light-shielded, a first correction unit configured to correct a shading component in the vertical direction that is included in an image signal from the effective pixel area of the plurality of lines, according to a first correction signal from the light-shielded area of the plurality of lines, and a second correction unit configured to correct the image signal output from the first correction unit according to a second correction signal obtained by multiplying the first correction signal, which is in the same line as the image signal, by a coefficient for decreasing a signal level of the first correction signal.
