Further experiments with a £12-80, 1000 line circuit board TV camera.

Nicola Mackin's Aspect Ratio Converter can scale the image up or down during correction:

Remounting the board camera in a project box.

I decided to mount the camera without any of the lens housing, and with a C/CS mount on the outside of the project box. The advantage of this is that a 2" adapter can be used if required, and the chip is unfiltered. The disadvantage is that the chip is more exposed, and with a project box that is not black, light can enter through the walls of the box. This is not usually a problem as vastly more light comes from the subject than through the box walls.
The circuit board camera

If a webcam adapter was to be used, then the square filter could be removed from the bottom of the lens thread. In either case, an IR/UV cut filter ac be attached to the adapter, if a filter is required.

Note that the camera case is actually grey, but the flash has made it appear to be white.

Using a two inch adapter

This camera works fine with a USB capture card, which effectively turns it into a powered USB camera.

Under Windows 8.1, this USB capture card works fine. New cards cost as little as £6 on Amazon.
