Electronic imaging apparatus with dithered color filter array
First Claim
Patent Images
1. An electronic imaging apparatus comprising:
- an electronic image sensor including a plurality of photosites arranged in two fields in a two-dimensional array;
a color filter array including a Dithered 3-G (three green) pattern of red, green and blue filter elements located over the two-dimensional array of photosites, wherein the red and blue filter elements from one field are each vertically aligned to respective red and blue elements in the other field, and the red and blue filter elements in adjacent lines within each field are horizontally offset by one filter element with respect to each other, so as to correspond to a predetermined interleaved chrominance channel pattern; and
means for scanning the image sensor to generate an image output signal.

Abstract
A color filter array for use with an electronic image sensor is disclosed, wherein the red and blue filter elements of the color filter array are arranged to correspond with an interleaved chrominance channel pattern. Thus, actual red and blue values are utilized to generate interleaved chrominance channel information instead of interpolated values as required by conventional CFA patterns.
