Description
LUT type
type
Designate gamma (1D-LUT) or gamut (3D-LUT).
• gamma: For gamma table
• gamut: For color gamut
Number of lattice
points
size
• When the LUT type is gamma: Designate one of 128, 256, 512 or
1024.
• When the LUT type is gamut: Designate one of 9, 17, 33 or 65.
Number of bits*
bit
32F (32-bit floating decimal point, range: 0 to 1). Fixed value.
Note: Handling of data outside this range results in an error.
Lattice point array
format*
order
Only when the LUT type is gamut. Designate top or bottom. The
default when not designated is top.
• When top is designated, add LUT data in the following order.
Start: (0, 0, 0), (1, 0, 0), (2, 0, 0) ……, (last, 0, 0)
⇒ (0, 1, 0), (1, 1, 0), (2, 1, 0) ……, (last, 1, 0)
⇒ (0, 2, 0), (1, 2, 0), (2, 2, 0) ……, (last, 2, 0)
• When bottom is designated, add LUT data in the following order.
Start: (0, 0, 0), (0, 0, 1), (0, 0, 2) ……, (0, 0, last)

Equal (even interval). Fixed value.
Actual LUT data
values
• When the LUT type is gamma
Method of noting one line: Gamma value (line break)
• When the LUT type is gamut
Method of noting one line: Red (tag) Green (tag) Blue (line break)
Note: The limit number of characters for 32F is 10 characters or
less (integer portion + decimal point + decimal portion).
