Abstract
An image sensing apparatus includes a pixel array, a first color filter, a second color filter, and a light shielding portion. The amount of electric charges generated in a first pixel after light of a first wavelength enters the first pixel is larger than that of electric charges generated in a second pixel after light of a second wavelength enters the second pixel. The light shielding portion defines the aperture regions of the first and second pixels so as to set the aperture area of the first pixel larger than that of the second pixel.
