Abstract

A means for obtaining both a rectangular and a log-spiral representation of images is examined. A method which utilizes a single CCD imager is examined in detail. The method uses a pixel combination process to form the log-spiral representation. The additional circuitry which is necessary to perform this combination process is discussed. The combination process used forms a log-spiral representation which is distorted. A means for quantifying this distortion is developed. Variations of the general method are considered in which the geometry of the CCD imager's photosen-sors are varied. A CCD imager with square, rectangular, and triangular shaped pixels is considered. To compare the different methods the amount of distortion introduced to the log-spiral representation is determined by direct calculation for each of the camera configurations. The results suggest that a camera with varied pixel shapes could form a log-spiral representation with less distortion.
