Abstract
A disclosed imaging device includes an imaging element that includes a plurality of pixels including a plurality of first pixels each of which outputs a signal including color information and a plurality of second pixels each of which has higher sensitivity than the first pixels, and a signal processing unit that processes a signal output from the imaging element. The signal processing unit includes a luminance signal processing unit that generates luminance values of the first pixels based on signals output from the second pixels and a false color determination unit that determines a presence or absence of false color based on a result of comparison between the luminance values of the first pixels generated by the luminance signal processing unit and a predetermined threshold value.
Claims19
An imaging device comprising:
- an imaging element that includes a plurality of pixels including a plurality of first pixels each of which outputs a signal including color information and a plurality of second pixels each of which has higher sensitivity than the first pixels;
- and
- a signal processing unit that processes a signal output from the imaging element,
- wherein the signal processing unit includes
- a luminance signal processing unit that generates luminance values of the first pixels based on signals output from the second pixels, and
- a false color determination unit that determines a presence or absence of false color based on a result of comparison between the luminance values of the first pixels generated by the luminance signal processing unit and a predetermined threshold value.
A signal processing device that processes a signal output from an imaging element that includes a plurality of pixels including a plurality of first pixels each of which outputs a signal including color information and a plurality of second pixels each of which has higher sensitivity than the first pixels, the signal processing device comprising:
- a luminance signal processing unit that generates luminance values of the first pixels based on luminance information output from the second pixels;
- and
- a false color determination unit that determines false color by comparing the luminance values of the first pixels generated by the luminance signal processing unit to a predetermined threshold value.
An imaging system comprising:
- an imaging device including an imaging element that includes a plurality of pixels including a plurality of first pixels each of which outputs a signal including color information and a plurality of second pixels each of which has higher sensitivity than the first pixels;
- and
- a signal processing unit that processes a signal output from the imaging device,
- wherein the signal processing unit includes
- a luminance signal processing unit that generates luminance values of the first pixels based on luminance information output from the second pixels, and
- a false color determination unit that determines false color by comparing the luminance values of the first pixels generated by the luminance signal processing unit to a predetermined threshold value.
