When do PRV_CNT_BRT parameters get applied?

Hello,

After looking at the DM37xx TM, I was wondering if someone might be able to clarify at what stage in the ISP Previewer pipeline do the contrast and brightness values defined in the PRV_CNT_BRT register actually get applied.

According to the documentation, it says that BRT is applied after CNT adjustment, and that CNT is applied after offset adjustment.

My question is, which offset adjustment?  Are they referring to PRV_CSC_OFFSET?

Thanks,

Sam

    Hi Sam,

    You are right. You should configure first the PRV_CSC_OFFSET register and then configure the PRV_CNT_BRT register. The necessary steps for preview configuration are described in the TRM section 12.6.1.4.2 Initial Configuration, page 1686.
