Acquisition Section - Matrox Corona Installation And Hardware Reference

Acquisition section

The acquisition section of the Matrox Corona provides three
different methods of capturing images. It uses a video decoder
to capture monochrome RS-170/CCIR, composite NTSC/PAL
(CVBS), and component NTSC/PAL (Y/C) formats. It uses an
RGB digitization section to acquire monochrome or RGB analog
video from standard and non-standard cameras. In addition, it
uses a digital interface to capture digital video (using the
companion digital-input board).

Three 256x8-bit lookup-tables are included to map the video
data stream. Matrox Corona also supports synchronous and
asynchronous triggers for monoshot acquisition. It provides two
exposure signals and can receive and generate syncs and the
pixel clock.
