False Color Display Appendix 259
A.3 False Color Display
The false color display is a tool to check correct exposure. It can be
activated on EVF and MON OUT, and takes the respective gamma
setting as a basis for calculation. When active, the image is turned into
a greyscale image with important luminance ranges shown in signal
colors. Note that the false color tool is only suitable for checking
exposure and is not an appropriate tool for checking other image
parameters or sensor quality.
Color Encoding
Six different colors are used to show the important luminance ranges.

The following example illustrates the behavior of the false color
display.
