The user guide show that the LUTs in the FPC module of VPAC1 and VPAC3 are different
I chose DCC-->VPAC3-->VPAC3 CFAI+WDR-->CFAI-V3 --> VPAC1 or VPAC3,
but lut is the same
note:DCC VERSION:2.50

Hi,
Yes, the difference is in H/W, but 16-bit is designed for special machine vision requirements where local tone mapping is not used.
Tuning tool programs FCP in the same way for VPAC1 and VPAC3 as local tone mapping is used for both.
FYI, we tested on j721e (VPAC1) and j721s2 (VPAC3) EVMs with PSDK compiled accordingly (same DCC settings for IMX390).
With the same input raw image, the YUV output images are exactly the same for j721e and j721s2.
