Embodiment Construction

[0038] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

[0039] 2 is a perspective view of an image sensor for improving image quality according to an exemplary embodiment of the present invention, and FIG. 3 is a partial plan view illustrating a configuration of a color filter array shown in FIG. 2 .

[0040] As shown in FIG. 2 , an image sensor for improving image quality according to an exemplary embodiment of the present invention includes a scanning unit 140 , a color filter array 120 and a photoelectric conversion semiconductor device 110 . In this case, it is preferable that the microlens array 130 is formed on top of the color filter array 120 .

[0041] By connecting an end of the scanning unit 140 to the color filter array 120, the scanning unit 140, which is a support moving on one plane, functions as a support capable of fixedly mounting the color filter array 120. The scanning unit 140 may...

Abstract

Provided are an image sensor for improving image quality and an image sensing method using the same, which can improve the quality of a sensed image without changing resolution of a color filter array and a photoelectric conversion semiconductor device for sensing an image. The image sensor for improving image quality includes: a scanner unit movable on a plane; a color filter array fixed on the scanner unit; and a photoelectric conversion semiconductor device including a plurality of pixels aligned beneath the color filter array.

Description

technical field [0001] The present invention relates to an image sensor and an image sensing method for improving image quality, and in particular to an image sensor for improving image quality and an image sensing method using the same, which can improve the sensed image quality without The resolution of the color filter array and the photoelectric conversion semiconductor device for sensing an image is not changed. Background technique [0002] As is generally known in the art, image sensors convert optical information in one or more dimensions into electrical signals. Among image sensors, a photoelectric conversion semiconductor device that converts an optical image using a semiconductor substrate into an electrical signal is classified into two types, a metal oxide semiconductor (MOS) type and a charge coupled device (CCD) type. [0003] A Complementary Metal Oxide Semiconductor (CMOS) image sensor is a device that converts an optical image into an electrical signal by ...
