Abstract
The present invention provides an image-correction system, including an image-capture module, a first calculation module, a second calculation module and an output module. The image-capture module obtains an input image and a guide image. The first calculation module obtains a first correction image according to a first parameter and a second parameter, obtains the first parameter according to the mean value of the guide image, a variance value of the guide image, a mean value of the input image and a smooth function, and obtains the second parameter according to the first parameter, the mean value of the guide image and the mean value of the input image. The second calculation module obtains the ratio value of the mean value of the guide image and the variance value of the guide image. The output module outputs the first correction image.
