The VPC-5 is a 2D adaptive detail enhancer which selectively enhances the appearance of edges and textures without enhancing the appearance of noise. Separate controls are provided for both edge and texture enhancement as well as for the amount of enhancement to be applied in each dimension. A programmable threshold for discriminating textures from noise is also provided. Careful algorithm design and piecewise linear control ensure a well behaved response without large changes at the output in response to small changes at the input. Programmable overshoot clamping is provided to limit the amount of overshoot associated with enhancement. The VPC-5 Adaptive Detail Enhancer can be combined with the VPC-3 Mosquito/Block Noise Reducer to provide a complete suite of enhancement and noise reduction tools.
