DYNAMIC CONTRAST ENHANCEMENT USING DITHERED GAMMA REMAPPING

摘要

Embodiments of the present invention generally provide a processing system for a display device. The processing system includes a histogram circuit configured to process a first plurality of pixel values associated with a first image to generate a first histogram. The processing system further includes a boost circuit configured to analyze the first histogram to determine a first boost level. Additionally, the processing system includes an interpolation circuit configured to interpolate, based on the first boost level, between a first boost mapping and a second boost mapping to generate a first intermediate boost mapping. The interpolation circuit is further configured to determine a first plurality of boosted pixel values based on the first intermediate boost mapping.
