Help! There is a comet in my computer! 29

Figure 17. Image contrast and brightness. Images of the same comet are shown in A, B and C.

The grabbed images are shown as greyscale images (GV) and displayed also using an orange-

scale LUT (shown at the bottom). Image A has a high contrast (grey values 14 - 198, contrast

range 185). Image B has a lower contrast (grey values 6 – 85, contrast range 80). Image C has the

same contrast range as image B (80, grey values 82 - 161). However, in image C, the range of

used grey values is in the brighter part of the greyscale, hence image C is brighter than image B.

The relationship between the intensity of light emitted from the slide and grey values on the image

is shown in the right column. See text for details.
