    Picture aspect ratio—The picture aspect ratio is the ratio of the active pixel region to the active line region. For standard video signals like RS-170 or CCIR, the full-size picture aspect ratio normally is 4/3 (1.33). © National Instruments Corporation IMAQ PCI/PXI-1407 User Manual...

  • Page 30: Programming Video Parameters

    Chapter 3 Hardware Overview • Pixel aspect ratio—The pixel aspect ratio is the ratio between the physical horizontal size and the vertical size of the region covered by the pixel. An acquired pixel should optimally be square, thus the optimal value is 1.0, but typically it falls between 0.95 and 1.05, depending on camera quality.

  • Page 31: Acquisition Modes

    PCI/PXI-1407 receives an incoming video signal (composite or luminance) and an external CSYNC signal from an external connector. The PCI/PXI-1407 takes the incoming CSYNC signal and generates HSYNC, VSYNC, and PCLK signals. © National Instruments Corporation IMAQ PCI/PXI-1407 User Manual...
