Abstract
According to the functional diagnosis need of maglev test line communication base station,the system of image acquisition and compression based on OV7670 and ADV6 1 1 is designed.The control interface of OV7670 image sensor based on SCCB bus protocol is completed using Verilog language.By configuring the OV7670 internal registers,the output data stream of image meets the international standard CCIR-601 .The image compression uses the chip of ADV6 1 1 which based on wavelet transform.In order to achieve a near con-stant compressed bit rate,the improved PID control algorithm is used during the process of calculating bin widths.关键词
