Abstract: An integral projection algorithm for Vector Quantization（VQ） is proposed in this paper，integral projection is used in every 4×4 block firstly，and then carry on vector quantity with the integral codebook.The memory area of codebook and computation of encode can be reduced greatly while the quality of the picture only loses slightly.To compare with standard VQ algorithm，the result of experiment shows that the encode speed can be improved greatly while the ordinary Peer Signal-Noise Ratio（PSNR） only reduced 0.25%.Compared with standard VQ，the quality of the decoded images can be improved in some particular image，the application of this arithmetic will have very good foreground.The architecture of encode circuit is designed，and verified in FPGA.The operation rate of the whole system can achieve 78.12 MHz.
