  • The Art of Color The Art of Color Detection Filters are deposited on top of the sensor array according to the Bayer pattern. pixels with filter sensor array G: Green color detecting pixels for luminance (brightness) signal  R, B: Red and Blue color R B: Red and Blue color detecting pixels for chrominance (color) signal 
  • What about a sensor that about a sensor that… is as sensitive as CCD CCD, is as compact, low power consuming and low cost compact as CMOS, does not require filters to detect color images.
  • Our Technology The filterless color i Th fil l l image sensor relies on the well‐known li h ll k principle of wavelength penetration into solids (silicon).  light ray silicon surface ili f λ(red) = 650 nm λ(green) = 530 nm λ(blue) = 470 nm
