Imaging device

Abstract

An imaging device includes plurality of illumination elements interspersed among a plurality of light sensing elements so that each illumination element is adjacent to a light sensing element. The illumination elements each include a ferroelectric liquid crystal element positioned over a LED. The light sensing elements each include a photodiode. The illumination elements and the light sensing elements are arranged so that adjacent to each illumination element is a light sensing element. Illumination control logic can selectively illuminate each of the illumination elements. The light sensing elements are coupled to analog shift registers. The light sensing elements generate charges related to the intensity of the impinging light. Sensor control logic is used to load the charges generated by the light sensing elements corresponding to the illuminated illumination elements into the shift registers. The charge data in the shift registers is sequentially shifted to the input of an amplifier. The amplifier generates a voltage proportional to the value of the charge data.
