| Abstract: | It is a problem to trace and record the growth of the large number of cells manually for a long time.Aiming at the mass data,high sampling frequency,complex caculation and other problems in cell image transmission,a novel method of video image acquisition is described.The key problems in the design of DSP(digital signal processors) system and FPGA(field programmable gate arrays) logic control system and the implementation of JPEG image compression algorithm are also discussed.The system basically consisted of enhanced video input processor,FPGA,DSP and other components.It is favorable for its integrated functions,simple structures and flexible complier.It provides a solution for the image acquisition of long time tracing and recording lagre number of cells,and also has the function of after image processing. |
