Converter translates Bayer raw data to RGB format

摘要

CMOS image sensors include the color filters of an RGB (red/ green/blue) Bayer array, which lets the sensor detect colors. The image data, the output from the image sensor, is Bayer raw data (Figure 1). Unfortunately, most consumer-grade image-dis-rnplaying devices require an RGB-imagedata format with red, green, and blue in each pixel's data. Therefore, you often need a Bayer-raw-data-to-RGB converter between an image sensor and a displaying device. This Design Idea describes such a converter in VerilogrnHDL (hardware-description language).
