摘要： The resolution of a low-resolution image is made high and a stereoscopic image is displayed. Resolution is made high by super-resolution processing. In this case, the super-resolution processing is performed after edge enhancement processing is performed. Accordingly, a stereoscopic image with high resolution and high quality can be displayed. Alternatively, after image analysis processing is performed, edge enhancement processing and super-resolution processing are concurrently performed. Accordingly, processing time can be shortened.

摘要： Techniques for de-noising a digital image using a multi-band noise filter and a unique combination of texture and chroma metrics are described. A novel texture metric may be used during multi-band filter operations on an image's luma channel to determine if a given pixel is associated with a textured/smooth region of the image. A novel chroma metric may be used during the same multi-band filter operation to determine if the same pixel is associated with a blue/not-blue region of the image. Pixels identified as being associated with a smooth blue region may be aggressively de-noised and conservatively sharpened. Pixels identified as being associated with a textured blue region may be conservatively de-noised and aggressively sharpened. By coupling texture and chroma constraints it has been shown possible to mitigate noise in an image's smooth blue regions without affecting the edges/texture in other blue objects.

摘要： Systems and methods for generating a detail-enhanced video signal are provided. In a method for generating the detail-enhanced video signal, an input video signal is received. A first signal that is a linear transformation of the input video signal is generated. A detail signal is generated by determining a difference between the input video signal and the first signal, where the detail signal includes information that is added to the input video signal to generate the detail-enhanced video signal. A filtered detail signal is generated by removing noise from the detail signal. The filtered detail signal is multiplied by a gain function to generate a second signal. The gain function is based on an amount of variance in the input video signal. The input video signal and the second signal are combined to generate the detail-enhanced video signal.
