| Example of a camera module with integrated MEMS AF |
Another DOC flyer presents AF+shutter actuator, where the shutter design appears like mechanical style:
It's said to be fitting to 8.5 x 8.5 x 6mm camera module and has 1M cycles life time.
Amazing work!
ReplyDeleteWith an electrical shutter, camera module became extremely compact.
so electronic rolling shutter will be OK now!
ReplyDeleteWell, took quite a while, but "yay!" for the former Siimpel team! Hope it is a marketplace winner.
ReplyDeleteHow is this better than the lensvector solution?
ReplyDeleteWell, assuming not a lot has changed with the MEMS approach, it moves a lens. The MEMS motion is much more controllable, repeatable, and more shock resistant than the predominant voicecoil AF. The Lensvector solution is to change the refractive index of an optical element. So, I think from a large resolution sensor point of view, moving the lens will give better optical performance than changing the refractive index in an unmovable lens. I am not an optics guys but I think when you change the index of one lens you should also change the prescription of all lens in the stack for optimum performance in secondary metrics. Maybe it is not so important however and the LensVector solution is good enough.
ReplyDeleteWhat phones or modules use the LensVector technology?
LensVector not be applied on any mobile phones.
DeleteI wonder what are the costs?
