Use the lowest frequency clock you can get away with.  I assume that the
internal RC oscillator on the parts that have them are lower noise than a
crystal.  Anyone comapred this?  .1uF ceramic and an electrolytic cap on the
power input to the pic.  Ceramic cap as close as possible.  All circuit board
traces as short as possible, especially crystal traces if used.  Big ground
plane.  Power supply isolated from camera power supply.  Pins on PCB cut as
short as possible.  Locate PIC in camera far away from low level svideo
signals.  PIC circuit in metal can with feedthru caps for real troublesome
cases.

Chances are that one or two of these will do the trick.  Moving the PIC circuit
somewhere else in the camera, grounding correctly and using caps will most
likely cure the problem.
