Are there any limits for how long the PassiveScan can be activated before you get any heat or power issues?
Ref:
MLCameraMetadataControlAFState_PassiveScan:
AF is currently performing an AF scan initiated by the camera device in a continuous autofocus mode.
Hi there, I'm reaching out to our engineers and will reply asap. Thanks very much.
Right now our answer is no, currently we do not have time limits on the AF scan. Theoretically, once AF converges the lens will not move again until the scene changes so it shouldn't be moving continuously, but even if it did our engineers have not yet seen any issues related to heat and/or power with the lens.
