Color image capturing system with antialiazing

Abstract

In a digital still camera (DSC) a plurality of individual RGB filter elements each overly a corresponding one of a plurality of photosensitive elements of an image sensor such as an array of charge-coupled devices (CCDs). A coated mirror is positioned along a light path between a lens and the image sensor for shifting the light transmitted through the lens so that a portion of the incident light that would otherwise fall on a single photosensitive element is divided between at least two adjacent photosensitive elements. The plurality of individual RGB filter elements are arranged in a predetermined mosaic pattern between the lens and the image sensor for permitting the photosensitive elements to detect the intensity of the light incident thereon in a manner that allows a high quality color image to be reproduced. A processing circuit is mounted in the housing and is connected to the image sensor for processing the output signals from the image sensor. A control circuit is mounted in the housing and is connected to the processing circuit for generating a color digital still image file and storing the file in a memory. Blurring and undesirable artifacts such as color fringing at the edges of the color digital still image are reduced.
