I'm trying to a picture of an image I have paused on a Sony camcorder. The LCD is 6.2cm and has a pixel of 560x220. I'm using a Canon PowerShot SX40HS. I have the Canon on a tripod, micro setting, and have tried ISO 200,400,800,different light settings and still the image shows a lot of grainy little dots.(I guess the pixels of the camcorder image). I cannot get this camcorder disc to load on my computer and I really want this frame to come out clean. Can you help?
As was mentioned by @ElendilTheTall, using a TV screen will provide a much better quality image than the small camcorder screen. The TV will have it's own problems though.
You need to have a long enough exposure to allow for the screen's refresh rate and any interlaced content to be displayed, otherwise you may get odd patterns on the screen (lines, darker sections, completely black or white screen).
A good starting point would be to use a 1/30 sec or longer shutter speed. That should be long enough regardless of the screen type to give you a clear image.
