Title:
DEVICE FOR INCREASING CONTRAST AND DISPLAY
Document Type and Number:
WIPO Patent Application WO/2020/000538
Kind Code:
A1
Abstract:
A device for increasing the contrast and a liquid crystal display. The device comprises: a storage module (101), for storing an input image; a histogram module (102), for performing histogram processing on the input image to obtain a histogram corresponding to the input image; a mapping module (103), for performing mapping processing on the histogram to obtain a mapping table corresponding to the input image; a computing module (104), for performing interpolation processing on the input image according to the mapping table to obtain a target image; an image synchronization module (105), for synchronizing the input image with the target image; an image joining module (106), for joining the input image and the target image and outputting the resulted image. The device can realize a method of adjusting the contrast of an image on the basis of a local histogram by means of a hardware circuit, requiring less time than using a software to improve the contrast of an image, satisfying the application requirement for product applicability.
