I BELIEVE THAT CONTOURS OUT OF GREEN WAS AN EARLY ATTEMPT TO ENHANCE PICTURE OF NORELCO PC-70 CAMERAS. A PORTION OF THE GREEN SIGNAL COULD BE ADJUSTED AT MODULE ON CCU. EARLY VERSIONS OF PC-60 AND PC-70 WITHOUT ENHANCEMENT PRODUCED SOFT PICTURES UNTIL PROBLEM WAS SOLVED.
THE CHARGES TO YOUR CREDIT CARD WERE FOR GAS MASKS PROVIDED BY MEDCO DURING 1968 DEMOCRATIC CONVENTION.
PLEASE READ THE FINE PRINT.
Yes, Contours out of green was the original name of the "Image Enhancer."
It involved the use of 1H and 2H glass delay lines. When it was first used
on air at the B.C., Cronkite didn't like it because it made the lines on his
forehead stand out! Viewers were also surprised to see a shot of a snowfall,
but there weren't any snowflakes coming down... the image enhancer had
made them disappear! After that, they were very careful about adjusting the
amount of enhancement provided!
