Abstract
A video encoding apparatus for Bayer pattern images is disclosed, comprising: a quantizer, a variable-length coder and a predictor. The quantizer is configured to perform quantization over a difference value D between an input pixel and a current predicted pixel to generate a quantized value Δ in a quantization sequence based on a quantization parameter Q and the following equation: Δ=└(|D|+└Q/2┘+1)×A/N┘. The variable-length coder is configured to count a number ZR of consecutive zeros that either precede a following non-zero integer in the quantization sequence or are arranged in the end of the quantization sequence, to encode the number ZR of consecutive zeros into a first codeword by a first codeword set, and to encode the following non-zero integer into a second codeword by a second codeword set to produce an encoded bitstream.
