7.7 LUT
LUT (Lookup Table) converts original image value to certain level value. Since it is mapped one to one for each
level value, 12-bit output can be connected to 12-bit input. LUT is in the form of table that has 4096 entries between
0~4095 and provides 2 non-volatile spaces for LUT data storage. User can select whether to apply LUT or not and
the LUT to be applied using “sls” command.(See 9.12 LUT) See Appendix B for how to download LUT data in
camera.
