IMAGE SENSOR FOR IMPROVING THE IMAGE QUALITY AND METHOD OF SENSING THE IMAGE FOR IMPROVING IT

摘要

An image sensor for improving image quality and a method for sensing an image using the same are provided to change the position of a color filter by using the size of a conventionally used photoelectric semiconductor device and a color filter array, thereby improving the image quality of a sensed image without an increase of cost and the deterioration of sensing capabilities. An image sensor for improving image quality comprises a scanner unit(100), a color filter array(120) and a photoelectric semiconductor device(110). The scanner unit is movable on a plate. The color filter array is fixed on the scanner unit. The photoelectric semiconductor device has plural pixels arranged in the lower part of the color filter array. A microlens array(130) is additionally included in the image sensor. The microlens array is formed in the upper part of the color filter array corresponding to the pixels to concentrate light.
