Provided is a solid-state imaging apparatus, including: a pixel array including: a first, a second, and a third non-effective pixel rows each including a non-effective pixel configured to output a signal that is independent of an amount of incident light; and a second pixel region having effective pixel rows each including an aperture pixel configured to output a signal that is dependent on an amount of incident light; and a mixing portion configured to: mix a signal output from the non-effective pixel in the first non-effective pixel row and a signal output from the non-effective pixel in the second non-effective pixel row; mix the signal output from the non-effective pixel in the first non-effective pixel row and a signal output from the non-effective pixel in the third non-effective pixel row; and mix signals together, which are output from the aperture pixels in the effective pixel rows.
