Small Dsp-based Video Image Acquisition, Processing And Storage System

With special structure and imaging ability, electronic endoscope plays important rolein various fields of production and life in society. Traditional electronic endoscope can notdeal with digital record and process of imaging, but it is indispensable to modem medicaltreatment and industrial Non-destructive Testing (NTD) field. Based on this background,this thesis makes research on digital video capturing, storing and processing system, whichisportable with low power and high integrated.On the basis of widely researching into development actuality of electronic endoscopeand its imaging processing technique, according to image characteristic and the techniquerequirement of the electronic endoscope system, this thesis puts forward the system'soverall scheme, chooses the core chips, completes the schematic circuit diagram, PCBscheme, and then the emluator and verification of the PCB board. After these, the system'ssoftware design is completed, ultimately, the software and hardware combined debuggingis accomplished.Initial debugging results show that, the system's overall technique scheme is feasible,the hardware circuit and related system software can function correctly according to thedesign, and the image capturing, processing, system controlling, FAT16 file systemestablishing, CF card file storing and video outputting functions are accomplished. On thewhole, the expected aim is achieved.
