A circuit of high-resolution digital video camera,supporting 1.4 mega pixels and 7.5 frames per second was presented. ICX205AK is used as CCD sensor,AD9923A is used as the analog front end,and other chips include XC3S1200E and TE3310RPF. The AD9923A converts CCD analog signal to digital signal,and the digital signals are sent to XC3S1200E which converts Bayer signals to YUV signals. The YUV signals are input to TE3310RPF to generate JPEG data. AT91RM9200 sends the JPEG data to network. The testing results show that image can be collected,compressed,and transmitted with 1.4 mega pixels image 7.5 frames per second by this design.
