Sequential filtering for color image acquisition.
We present an alternative method of color imaging. It utilizes a single standard Si-based image sensor and a clear aperture, tunable, color filter. Within this scheme, three monochromatic frames are taken; each is acquired with a single color and with a fraction of the total acquisition duration. This scheme offers several advantages compared to standard Bayer-demosaicing schemes. Among them - significantly higher resolution, flexibility in exposure durations, improved noise performance and in sum - better image quality. This paper presents both color filter design and the adjusted image pipeline. Lastly, the proposed imaging scheme and the Bayer scheme are compared in terms of MSE.
