Solid-state imaging apparatus, method of controlling the same, and imaging system

A method of controlling a solid-state imaging apparatus,

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