OPT8241: HDR frame and normal frame definition is not match to datasheet.

CHOU HAUNTING

Part Number: OPT8241

Hi Larry/Gupta:

I want to use HDR in our camera,

but we found that flags supposed to show me where the HRD frams are turned out pointing to the normal frames and vice versa.

This reverse in flag further leads to the failure of setting HDR offset,if i use the HDR_phase_corr_1 register to fine tune HDR frame's phase, it will work on the normal frame not HDR frame I wanted.

Do you have any solution about this?

thanks

Hi Chou,

I agree that the flags for HDR and the normal frame are interchanged from the values given in the datasheet. Due to this, the phase_corr correction is getting applied to the HDR frame, while the hdr_phase_corr correction is being applied to the normal frame.

As a workaround, I suggest you to interchange the values of these registers.

In the meantime, we'll try to find a solution.

Hi Chou,

I am assuming the workaround solution works and will close the post now.
