Optical aberration correcting system and method of digital cameras

Abstract

The invention relates to an aberration correction system and method for a digital camera, which includes a piece of optical lens, a set of axial movement mechanisms, a set of photosensitive elements, and a set of image units. The photosensitive element is loaded on the axial moving mechanism, and can generate the first image and the second image at the first focus position and the second focus position. After receiving the first image and the second image, the image unit calculates the first image acquisition area and the second image acquisition area respectively and merges these image acquisition areas into a third image. The method of the present invention includes projecting the light of the object to be photographed by the optical lens, generating the first image, generating the second image, and acquiring clear parts of the first image and the second image to merge into a third image. By providing the aberration correction system and method described above, the present invention solves the phenomenon that the definition of the center of the image is different from that of the surrounding area.

Description

technical field [0001] The invention relates to an image processing system and method, in particular to an image aberration correction system and method applied to a digital camera. Background technique [0002] The basic imaging principle of a digital camera (Digital Camera, DC) is similar to that of a traditional camera. It has a set of optical lenses including at least one lens. Using the optical principle of pinhole imaging, the light of the image you want to shoot is projected on the photosensitive sensor inside the camera. material. The photosensitive material of traditional cameras is generally film (or called film), while digital cameras generally use Charge Coupled Device (CCD) or Complementary Metal-Oxide-Semiconductor (Complementary Metal-Oxide-Semiconductor, CMOS) to As a photosensitive material (hereinafter collectively referred to as photosensitive elements). The photosensitive element of a digital camera can convert the image captured by the optical lens int...
