The Test Pattern

[jshorva65]

Here's a classic. This one is great for rectangular-mask sets. The famed "Indian Head" pattern. The original graphic isn't perfect, though, so the resolution marks are slightly blurred. I have been trying to find time to design a new test pattern.

I placed a printout of this under a TeleSensory "Chroma CCD" video inspection table unit that I use, connected its NTSC output to a VCR along with a 400-Hz audio source and hit "Record" so I now have a genuine test pattern tape for use in the shop.
