Title:
LOW ILLUMINATION ENHANCEMENT PROCESSING METHOD, DEVICE AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/076317
Kind Code:
A1
Abstract:
A low illumination enhancement processing method, device and computer readable storage medium. The method comprises: obtaining source image data (210); obtaining from the source image data a local area description value corresponding to each pixel (230); searching for an entry address of a table by using each pixel and the corresponding local area description value as a built-in color value, and immediately searching for a color value used when the pixel is displayed (250); updating the corresponding pixels in the source image data in real time by means of the color values obtained by immediately searching so as to obtain enhanced image data (270). With the present invention, since the color values mapped to the described pixels are obtained using each pixel and the local area description value corresponding to the pixel, at the same time that controllability is guaranteed, source image data are processed more meticulously, and thus the image enhancement effect is improved; furthermore, because of the simple algorithm and the built-in color value search table, real-time performance may also be improved, and the support of high hardware configuration is not necessary, thus the invention may be applied in common hardware devices.
