Video image data acquisition method study
Tuesday, October 6th, 2009 at 06:44 | No commentsCategories: DSPShort Content: The video image gathering method are many, divides into 2 broad headings: Automatic image gathering and based on processor's image gathering. The former uses the special-purpose image gathering chip, completes the image automatically gathering, the frame memory address production as well as image data refurbishing; Besides must carry on the hypothesis to the gathering pattern, the main processor does not participate in the gathering process. This method's characteristic is gathering does not take CPU when asked that timeliness is good, ... -
