Abstract: An image sensing apparatus including a pixel array comprising two or more photo-sensor elements, a first optical filter disposed on a first photo-sensor element of the pixel array and a second optical filter disposed on a second photo-sensor element of the pixel array. The first optical filter is configured such that a spectral response of the first optical filter includes a first passband in a first wavelength range and a second passband in a second wavelength range, where the first passband and the second passband are separated by a first stop band. The second optical filter is configured such that a spectral response of the second optical filter includes a third passband in the first wavelength range and a fourth passband in the second wavelength range, where the third passband and the fourth passband are separated by a second stop band.
