Embedded Video Processing Using Microcontroller ATXMEGA32A4 Embcddcd Video Processing Using Micro controller ATXM EGA32A4

Abstract

This paper shows the design and implemetation of an embedded video processing system using ATCMEGA32A4 microcontroller. Im order to capture the video, the presented design uses an analogic video camera similar to the security video camera with NTSC video formar and RCA output. Using the TVP5146M2 video decoder and ATXMEGA32A4 microcontroller, the analogic video signal is digitalized and processed in order to obtain image fields and store them in a SRAM external memory, finally, is executed an images processing in order to detects motion based in one algorithm to compare image fields stored them in the SRAM memory.
