Optical aberration correcting system and method of digital cameras

Abstract

The present invention relates to an aberration emendations system and method for a digital camera. The present invention comprises an optical lens, an axial movement mechanism, a group of photographic components and a group of image units. The photographic component is arranged on the axial movement mechanism and can generate a first image and a second image at a first focus place and a second focus place. The image unit receives the first image and the second image, calculates the acquisition area of the first image and the acquisition area of the second image and combines the two acquisition areas to a third image. The method of the present invention comprises steps as follows: the beam of the object to be photographed is projected by the optical lens; the first image is generated; the second image is generated; the clear parts of the first image and the second image are obtained and combined to the third image. The present invention solves the phenomenon that the definition of the center and the surrounding areas are different through providing the aberration emendations system and method.

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...
