False Color Mapping
The camera supports the use of false color to enhance contrast or reduce eye fatigue.
To use a false color mapping the pixel format must be set to YUYV. The following color
maps are available:
Greyscale: 8-bit monochrome
Fire: darker purple/blue indicates colder, yellow hotter
IronBlack: white-to-black ramp for low values, then color highlights (similar to
the Fire color map) for higher values
Custom: a user-defined mapping.
Figure 9: Fire Color Map
A user-defined custom color map can be uploaded using the
dialog;
select the “Miscellaneous” file type and “False Color Map” as the file. The file (.bmp) must
be a one line 256 column 24-bit per pixel bitmap. The X position (0-255) indicates the
pixel value and corresponding RGB value. Example color map files are provided in the
firmware distribution under the CustomColorMaps directory.
The color map range, represented as a bar of increasing pixel values and the
corresponding color, can be displayed as an overlay in the image (see the Overlays
section).
