The User LUT function incorporated in a Canon video display (hereafter, “display”) imports the
one-dimensional Look-up Table (1D-LUT) and three-dimensional Look-up Table (3D-LUT) created by
the user to the display and adjust s t he look.
The User LUT function is used as follows.
① Create a LUT file (clut format file).
② Import the created LUT file to the display via a USB memory.
1. Concept Drawing of Display Image Processing and User LUT
About the LUT file (1D-LUT)
• The settings after [1D-LUT] are gamma = 2.2 and quantization range = Full Range. Therefore, the
1D-LUT file to be import ed to [1D-LUT] should be created in consideration of a gamma of 2.2.
• When linear data is set in the 1D-LUT file, the dis play characteristics are gamma = 2.2 and color
temperature and color ga mut values set by the OSD menu.
About the LUT file (3D-LUT)
• The settings after [3D-LUT] are gamma = 2.2, color temperature value set by the OSD menu, and
color gamut (base color g amut) set by the O SD menu w hen i mport ing th e 3D-LUT file to the display.
Therefore, the 3D-LUT file to be imported to [3D-LUT] should be created in consideration of these
settings.

• When linear data is set in the 3D-LUT file, the display characteristics are the gamma, color
temperature and base co l or gamut set by the OSD menu.
• Regardless of the [1D-LUT] settings, when setting the 3D-LUT file without performing color
temperature image processing, set the color temperature setting in the OSD menu to “DCI”. In this
case, the display charact eristics are ga mma = 2.2, color temperature = DCI, and color ga mut = base
color gamut.
About the base color gamut
• The base color gamut is the color gamut used as the reference when creating a 3D-LUT. The base
color gamut can be select ed from SMPTE-C, EBU, ITU-R BT.709, Adobe RGB, DCI or Native. This
is set by the OSD menu when import ing the 3D-LUT file to the display.
