Problems solved by technology

In this case, if the red R and blue B signals are distorted by noise, an error such as fixed image noise occurs in the CMOS image sensor
Also, if white and dark noise dominate due to lack of consistency in the manufacturing process, interpolation becomes less precise due to fixed image noise, which makes it impossible to extract accurate color information for each pixel

Abstract

The invention relates to an image sensor and an image processing apparatus using the same having a color filter array with open window cells alternating with single color filter cells. The image sensor includes a lens array containing a plurality of microlenses, a color filter array having a plurality of open window cells and color filter cells, each corresponding to each microlens. The image sensor also includes a protection layer, and a pixel sensor array having a first photosensor sensing a first light passed through each color filter cell, a second photosensor formed under the first photosensor, sensing a second light passed through each color filter cell, a third photosensor sensing a third light passed through each open window cell, and a fourth photosensor formed under the third photosensor, sensing a fourth light passed through each open window cell.

Description

[0001] This application claims priority from Korean Patent Application No. 2005-44149 filed in the Korean Intellectual Property Office on May 25, 2005, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to image sensors and image processing devices used in video cameras, digital still cameras, and the like. More particularly, the present invention relates to an image sensor for a semiconductor photosensitive device using a color filter array having open windows and monochromatic color filters alternated with each other, and an image processing apparatus using the same for Multiple color information is used per pixel to enable more precise interpolation, which is used to extract more precise colors per pixel. Background technique [0003] In general, recent developments in image communication by means of wired / wireless high-speed network systems, and image input and recognition technologies such as those u...
