Document Type and Number:
WIPO Patent Application WO/2019/090909
Kind Code:
A1
Abstract:
The present invention provides a method and device for improving the contrast of a Bayer image. The method comprises: respectively obtaining dark primary color image data of a bottom portion, a middle portion, and a top portion of a pixel unit in the current Bayer image data; managing the obtained dark primary color image data in time-sharing fashion, obtaining integral values of a top left region TL and a top right region TR by means of the dark primary color image data of the top portion, obtaining integral values of a bottom left region BL and a bottom right region BR by means of the dark primary color image data of the bottom portion, and forming an integral image; performing comprehensive processing on the integral image and the integral values of the top left region TL, the top right region TR, the bottom left region BL, and the bottom right region BR, and then preforming bilateral filtering processing to obtain filtered dark primary color image data; and performing computational processing on the filtered dark primary image data to obtain Bayer image data having improved contrast. The method simplifies an intermediate processing procedure and reduces processing delays while ensuring the contrast and detailed information of an image.
