Auto Image menu
The Auto Image menu causes the MGP 462 to perform an automatic image
adjustment to the selected window. Auto Image measures where the active area
starts and stops, and adjusts input sampling accordingly.
When Auto Image is performed, the processor measures the sync frequencies of
the incoming video source and sets the active image area, total image area, and
sampling frequency according to a table stored on the MGP. If an unknown input
is connected to the MGP, the processor measures and estimates the resolution of
the incoming video. If the estimate proves not to be accurate, the Auto Image
function makes measurements to more accurately set up the input sampling.
