Abstract

A linear current mode computational image sensor is presented in this paper. The sensor monolithically combines current mode imaging elements with current mode digitally programmable analog computational circuitry at the focal plane. The pixel is based on a switchless paradigm and allows for reduced spatial and temporal noise imaging. The imaging array is composed of 128-by-109 pixels. The image sensor provides a noise-corrected image in conjunction with a convolved image in parallel at 50 fps and 50 mW. The maximum measured SNR is 44 dB, maximum FPN of saturated value (after DDS) is 0.22%, and DR is 55 dB.
