Paper Abstract

This paper describes image reading technique using multi area sensors for building a high- speed full color still image reader. An experimental system has been created using four CCD imagers which are located symmetrically on the optical axis and optically coupled to the same lens. To produce four images at each surface of the imagers, a pyramidal mirror is placed between the lens and its focal plane. Each CCD sensor reads a quarter section of the original image, and the four images are combined into one image like the original by signal processing. Image discontinuity, which is caused by the differences in characteristics among the CCD imagers, can be decreased below the perception of the human eye by signal correction processing and the read image can be output as a seamless image.
