Contrast; Gamma; Hue; Saturation - Tormach CNC Scanner Manual

5.4.2

Contrast

The amount of gradient between the darkest pixels and lightest pixels in the image. Higher contrast will
lighten the lightest pixels and darken the darkest pixels.
5.4.3

Gamma

Signal correction between Scope and Display monitor.
5.4.4

Hue

The distinguishing attribute of color.
This is what makes red different than
blue, for example. When moving this
slider, think about moving around a
color wheel from 180⁰ to -180⁰.
5.4.5

Saturation

The amount of grey in a color. Lower
saturation has more grey, higher
saturation has less grey.
5.4.6

Sharpness

The clarity of detail in an image. Higher
sharpness means more abrupt
transitions between different colors.
5.4.7

Snapshot Size

Options will depend on Hardware.
5.4.8

USB Bandwidth

The rate of data transfer between from
the scope in Mb/s. Choose the highest
rate possible; however, it may be
necessary to reduce bandwidth if you
notice problems with the function of
other USB devices, such as the Tormach
Jog Shuttle. This is dependent on the
performance of the control computer.
5.4.9

Exposure

Total amount of light collected during
image capture. Higher exposure
improves images taken in low light, but
too much can "washout" features.

5.4.10 White Balance

Adjusts images for the differences in spectral composition of white light originating from different
sources (i.e., LEDS, sunlight, florescent tubes, etc.)
