Embodiment Construction

[0022] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] Referring to FIG. 1 , an imaging system provided by an embodiment of the present invention includes: a lens module 10 , a detection unit 20 , a database storage unit 30 , a control unit 40 , an image processing unit 50 and a storage / display unit 60 .

[0024] The lens module 10 is used for imaging an object to obtain an image of the object and generating an image signal. The lens module 10 generally includes a lens device 12 and an image capture device 14 . The lens device 12 is used to collect light reflected from the object to be photographed and form an image; the image capture device 14 is used to convert the image of the object to be photographed formed by the lens device 12 into an image signal. The lens module 10 can be a zoom lens commonly used in current digital cameras, such as a two-component zoom lens, a three-component ...

Abstract

This invention relates to an imaging system and a method, in which, said system includes: a lens module used in imaging shot objects and generating image signals, a test unit used in testing the working parameters of the lens module at work, a database storage unit used in storing chromatic collection volume and single color image difference correction volume at various working parameter conditions, a control unit used in receiving the working parameters tested by the test unit and obtaining chromatic correction volume and single color image difference correction volume corresponding to the working parameters from the storage unit of the database to generate the correction parameter, an image process unit used in receiving the image signals generated by the correction parameter and the image module to be corrected and output based on the correction parameter.

Description

【Technical field】 [0001] The invention relates to an imaging system and method, in particular to a system and method for correcting chromatic aberration and monochromatic aberration for digital images. 【Background technique】 [0002] Imaging systems such as video cameras and digital cameras mainly include lens modules for forming images of objects, image processing units for processing captured images, and storage units for storing processed images. When taking pictures, the light reflected by the object to be photographed enters the lens module to form an image, which is converted into an electronic image signal and processed by the image processing unit before being output to an external device or recorded in a storage medium. [0003] However, when the lens device in the lens module is in the telephoto or wide-angle shooting state, the internal optical lens will affect the imaging quality and cause image distortion; and when the polychromatic light enters the lens device,...
