DM388 autofocus value

Other Parts Discussed in Thread: DM388

Hi, TI,

The chip is DM388.

I control the motor position of CMOS sensor to search the peak of autofocus value.

I use two functions(  CameraLink_getAfData and CameraLink_getFocusValue).

(IOCTL_ISS_CAPT_GET_FOCUSVALUE  and  IOCTL_ISS_CAPT_GET_AFDATA)

But the wave is not correct.

Can you tell me what is the difference between CameraLink_getAfData and CameraLink_getFocusValue?

Which one is correct for me to find out the best value of focus?

or Any suggestion.

Many Thanks.

Yours Sincerely,

S.K.
