Abstract
This investigation applied the current-mode pixel cell to reduce the design complexity and to embed a local threshold algorithm for edge detection in a mixed signal CMOS image sensor, which is successfully implemented as a low cost and highly integrated computational imager. The outcomes of the built-in adaptive and tuneable spatial filters for performing advanced functions of image binarization and edge detection are better than those in previous researches, in which the spatial filters are only based on crude algorithms. In this work, the proposed 66 × 66 CMOS imager has been fabricated in a 0.35um 2P4M CMOS technology of TSMC with a chip size of 2.410 × 2.666mm 2.
