Abstract
A correction method for image color range conversion and an image-processing system are provided. In the correction method, when an image is received, an actual color range of the image can be obtained by counting a pixel value of the image. A color range can be a full color range or a limited color range. If the actual color range is inconsistent with the color range recorded in an image packet, the image-processing system performs a color-range correction procedure. A linear mapping method can be incorporated for converting pixels of the image from the limited color range to the full color range. In particular, the color-range correction procedure can be gradually performed in a multi-stage manner, so as to accurately and smoothly convert the color range of the image for a subsequent image-processing procedure.
