Abstract:
A feature-based contrast enhancement apparatus comprises a histogram calculator, a feature value calculator, a first combining circuit, a histogram equalizer and a remapper. By keeping the hardware cost as low as a picture-based contrast enhancement apparatus, the invention has an advantage of suppressing the background noise and enhancing the image details.
