It's off the topic of colour changes, I just thought I'd mention it
as an additional feature he has working on his notebook that someone
may find useful!
He is on a journalism course and wanted to be able to read
newspapers. We looked at various solutions. Obviously a CCTV system
would be best, but it is expensive and bulky. We looked at scanners,
but it was not an ideal solution - it was too slow for moving around
the paper.
The hand held camera was quite good, but it has no zoom control
so the text enlargement depends on the size of the TV you used with
it. The magnification was far too much for him.
As a result of something I saw at Sight Village last year we
experimented with a hand held camera connected to a video capture
card. This allowed the camera input to be displayed in a resizable
window on the PC. Resizing the window effectively gave you a form of
zoom control. However, he was not 100% happy with the quality of the
image. We then learned that certain newspapers could be delivered
by email and settled on that as a solution.
Later, he discovered a MPEG (Motion Picture Experts Group - the
standard being used for digital television) capture card that gave a
better quality image. This was available as a PCMCIA card for a
notebook slot. He is very happy using this with a hand held camera.
I hope this is clearer!
