When doing a search for weather resistant cameras, Olympus seems to rise to the top of the list. The Olympus – Stylus 7.1 Model: 790 SW is designed to be shock-, water-, freeze-, sand- and dust-resistant so you can take it with you to exotic locations for amazing shots.

Most problems like this are because the camera can take more colors than many TVs can reproduce.
Certain colors are too intense for the TV and will almost strobe and flicker. I am not directly familiar with the program Arcsoft... but there should be a “NTSC Color Safe” setting somewhere. This will insure that the colors stay within the safe viewable range.

The Canon ZR800 has a 2.7-inch LCD screen.

When using a compact camera, noise in the picture is common place in dark situations. The sensor in these cameras are very small, about the size of an eraser on a pencil or just slightly bigger. They need a lot of light to get a decent image. Changing to an entry level D-SLR would resolve many of your issues. D-SLR cameras have a much larger sensor which will need less light and give you better, truer color. More color also will give you a sharper image. The ISO (Sensitivity of the sensor) can also be set higher on a D-SLR and most cameras come with built in noise reduction. If a flash is needed, the one on a D-SLR is stronger covering more area and farther distance. There are entry level D-SLR cameras that start around $499 just a little more than a higher end compact or advanced camera.
