LUT File Formats Applicable to This
Board
Examples of the five lookup table (LUT) file formats
applicable to this board are shown below.
Line numbers (“Lx” in the tables below) do not appear in
the actual LUT files.
LUT file type 1: R, G, and B have the same value
(the same curve)
”LUT: 1 1024” in the header indicates one output data
block (common to R, G, and B) corresponding with the 10-
bit (1024) input data.
The bit depth of the output is determined by the maximum
output value.
(This is an example of 10-bit input and 10-bit output.)
LUT file type 2: R, G, and B have individual values
(individual curves) and are aligned vertically in
the order of R, G, B
“LUT: 3 1024” in the header indicates three separate
output data blocks (for R, G, and B) corresponding with
the 10-bit (1024) input data.
The bit depth of the output is determined by the maximum
output value.
The output values on lines L1 to L1024 are R values, the
values on lines L1025 to L2048 are G values, and the
values on lines L2049 to L3072 are B values.
(This is an example of 10-bit input and 10-bit output.)
LUT file type 3: R, G, and B have individual values
(individual curves) and are aligned horizontally
“LUT10” in the header indicates the bit depth of the output
is 10 bits.
The bit depth of the input is determined by the maximum
number of lines.
(This is an example of 10-bit input and 10-bit output.)
