Abstract
A color filter array for an optical image sensor comprising pixels that are arranged in a matrix or a line, each pixel being connected to an electronic circuit for converting the information concerning the luminosity of each pixel into electric signals. A rectangular color filter of a predetermined color is placed over each pixel and several pixels that are directly adjacent form pixel by pixel with color filters of different colors a base cell, a plurality of said base cells together constituting the matricial or linear image sensor. The aim of the invention is to create a color filter array for an optical image sensor, which reliably prevents the distortion of the color signals by unfiltered white light. The object is achieved by making the border regions between adjacent color filters of different color significantly less permeable to light as a result of an overlap or additional non-transparent strips.
