Abstract

This paper demonstrates, for the first time, TOMBO color imaging system that employs color-splitting filters on each lens. A red, green, or blue color filter is allocated to each microlens instead of each pixel in conventional single-sensor color imaging system. Thus the microlens array here also makes up a color filter array of Bayer geometry. For the imaging device, a CMOS image sensor with 1040 x 960 pixels whose size is 6.25 um square was used. 8 x 8 microlens array with 750 um pitch was employed as a taking lens. Excellent color images were obtained by rearrangement, interpolation, and postdigital processing.
