Content adaptive image restoration, scaling and enhancement for high definition display

An image processing system, comprising:

• a texture estimator and noise discriminator configured to receive a luminance component signal with a low resolution and comprising an image block with noise, generate a content adaptive kernel from the image block, convolve the adaptive kernel with the luminance component signal, and generate a noise signal and an extracted texture which excludes noise;
• a two-dimensional adaptive sharpener configured to receive the luminance component signal and the noise signal, filter the luminance component signal with noise inhibition, and generate an enhanced luminance component signal;
• a scaler configured to horizontally and vertically scale the enhanced luminance component signal, horizontally and vertically scale the extracted texture, and adaptively vertically and horizontally scale the luminance component signal as a function of the horizontally and vertically scaled extracted texture;
• and
• an image enhancer configured combine the horizontally and vertically scaled enhanced luminance component signal, horizontally and vertically scaled extracted texture and adaptively vertically and horizontally scaled luminance component signal to generate an output luminance component signal with a high resolution.
