Processor for image-pixel signals derived from divided sections of image-sensing area of solid-type image sensor

Abstract

An image-pixel signal processor is used to process image-pixel signals obtained from an image-sensing area, divided into a first section and a second section, of a solid-type image sensor. The processor has an image-pixel signal reader, which simultaneously and correspondingly reads two respective series of image-pixel signals line by line from the sections. A leading signal of the image-pixel signals, included in each line, is farthest away from a boundary between the sections, and a trailing signal of the image-pixel signals, included in each line, is nearest to the boundary. The processor has a regulator, which correspondingly regulates differences in level between the signals in each line derived from the first section, and the corresponding signals in each line derived from the second section, so that a gradual reduction occurs, resulting in both levels of the trailing signals, derived from the sections, being substantially coincident with each other.
