Figure 30. Single Line Mode
The line being analyzed is indicated with a contrastingly colored line, and the
number of the line is shown on the upper right.
Single Line Mode is turned on and off with the Analyzer Mode menu, or with the
CTRL+space hotkeys. Additionally the hotkey CTRL + Up/Down Arrow moves the
single line mode up and down one line at the time.
LUTs
Overview
Lookup Tables (LUTs) allow the mapping of colors between color spaces.
The HDR Image Analyzer allows external Lookup Tables (LUTs) to be used for two
different purposes:
• A Display LUT is only applied to the image being shown and does not aect
the actual analysis of the pixel values. This can allow an operator to look at a
correct image on a display device that does not match the current video signal
type.
• A Scope LUT is applied to the video signal being processed, so all scopes,
waveforms etc. will be based on the remapped image.
No external LUTs are provided with the HDR Image Analyzer. Users can create and
load custom LUTs, if desired, provided they are formatted as either a *.cube or
*.3dmesh LUT file.
LUT files are loaded into and deleted using the Setup > Manage LUTs menu
(Figure 31 on page 31), but are not active until selected for use as either an
Analyzer Scope LUT or an Analyzer Display LUT (Figure 32 on page 31), using the
Analyzer menu selections.
