A high dynamic range sensing device is disclosed. The device may comprise an array of Bayer-pattern units of color filters, each of the color filters corresponding to a pixel of the sensing device, and each of the color filters overlapping with a plurality of photodiodes.

System and method for high dynamic range image sensing

An apparatus for measuring the power frequency of a light source includes a photo-sensitive transistor, a modulators and a logic unit. The photo-sensitive transistor generates an electrical signal that is responsive to light incident thereon from the light source. The modulator generates a modulated signal based on the electrical signal that toggles at a rate substantially proportional to the power frequency of the light source. The logic unit is coupled to receive the modulated signal and determine its toggling frequency.
