Methods and apparatus for displaying HDR image on LDR screen

摘要

Methods and apparatus of displaying a High Dynamic Range (HDR) image on a Low Dynamic Range (LDR) screen are suggested. The suggested method comprises: performing bit conversion on the HDR image to obtain a LDR image; up-sampling the LDR image to obtain an up-sampled LDR image; dithering the up-sampled LDR image based on the HDR image; and displaying the dithered up-sampled LDR image on the LDR screen.
