Please note that ONLY 1x1 binned images will decode to colour – the other modes
are for focusing and acquisition only.
If you cannot record any kind of image, please check the following points:
1) Ensure that the power indicator lamp is on and that the cables are properly home
in their sockets.
2) If the screen is completely white, the image may be greatly overexposed. Try a
shorter exposure time, or stop down your lens. See if covering the lens causes the
image to darken.
3) If the USB did not initialise properly, the camera start-up screen will tell you that
the connection is defective. Try switching off the power supply and unplugging the
USB cable. Now plug in the USB cable, followed by the power. This will re-load
the USB software and may fix the problem after restarting the SXV_M25C
program. Otherwise, check the device driver status, as previously described, and
re-install any drivers which appear to be defective.
4) If you cannot find any way of making the camera work, please try using it with
another computer. This will confirm that the camera is OK, or faulty, and you can
then decide how to proceed. Our guarantee ensures that any electrical faults are
corrected quickly and at no cost to the customer.
Converting your image to colour:
Once you have a recognisable image, it is quite easy to convert it to full colour. The
‘raw’ image will appear to have a fine grid distributed across it – this is the colour
filter matrix and the variations of pixel brightness encode the colour data which we
want to extract. Here is an enlarged section of a raw image:
Click on ‘Colour Synthesis’ in the main menu and you will see the synthesiser dialog.
