Abstract
An imaging apparatus includes a plurality of pixel portions, each including a photoelectric conversion section and a holding section. The holding section is configured to hold a mixed saturation signal containing a saturation signal overflowing a photoelectric conversion section of the same pixel portion and a saturation signal overflowing a photoelectric conversion section of another pixel portion which functions as a color mixture component. A color mixture correcting section is configured to correct a color mixture component contained in the mixed saturation signal read out of the holding section. A combining section is configured to combine a photoelectric conversion signal read out of the photoelectric conversion section and a corrected saturation signal corrected by the color mixture correcting section.
Claims5
An imaging apparatus comprising:
- a plurality of pixel portions, each including a photoelectric conversion section and a holding section, wherein the holding section is configured to hold a mixed saturation signal containing a saturation signal overflowing a photoelectric conversion section of the same pixel portion and a saturation signal overflowing a photoelectric conversion section of another pixel portion which functions as a color mixture component;
- a color mixture correcting section configured to correct a color mixture component contained in the mixed saturation signal read out of the holding section;
- and
- a combining section configured to combine a photoelectric conversion signal read out of the photoelectric conversion section and a corrected saturation signal corrected by the color mixture correcting section.
A method for an imaging apparatus including a plurality of pixel portions, each including a photoelectric conversion section and a holding section, wherein the holding section is configured to hold a mixed saturation signal containing a saturation signal overflowing a photoelectric conversion section of the same pixel portion and a saturation signal overflowing a photoelectric conversion section of another pixel portion which functions as a color mixture component, the method comprising:
- correcting a color mixture component contained in the mixed saturation signal read out of the holding section;
- and
- combining a photoelectric conversion signal read out of the photoelectric conversion section and a corrected saturation signal subjected to color mixture correction.
