Video Processing Reference Design
from Altera Corporation
The video processing reference design shows how the cores provided in the Video and Image Processing Suite can be used to create a complete video system. The design uses Altera's DSP Builder and SOPC Builder tools and several of the IP cores, including chroma resampler, color space converter, and scaler. Table 1 contains a complete list of the cores that comprise the Video and Image Processing Suite. | Table 1. Video and Image Processing Suite Intellectual Property (IP) MegaCore®Functions | | Core | Description |
|---|
| Deinterlacer | Converts interlaced video formats to progressive video format | | Color Space Converter | Converts image data between a variety of different color spaces | | Scaler | Resizes and clips image frames | | Alpha Blending Mixer | Mixes and blends multiple image streams | | Gamma Corrector | Performs gamma correction on a color space | | Chroma Resampler | Changes the sampling rate of the chroma data for image frames | | 2D Filter | Implements 3x3, 5x5, or 7x7 finite impulse response (FIR) filter on an image data stream to smooth or sharpen images | | 2D Median Filter | 3x3, 5x5, or 7x7 filter that removes noise in an image by replacing each pixel value with the median of neighboring pixel values | | Line Buffer Compiler | Efficiently maps image line buffers to Altera®on-chip memory |
