What is VCM in camera?

Autofocus is one of the key features required for many embedded vision applications. An autofocus camera module is typically used when the distance to the target object keeps varying during image capture.

Do cell phone cameras have actuators?

Of the 2 billion cameras manufactured for the phone and tablet market, nearly half of them autofocus. Usually, one of more of the lenses in the camera are moved in or out using a linear actuator, while an algorithm calculates a figure of merit for the sharpness of image for that location of the lens.

What is a voice coil motor?

Voice coil motors (VCM) or voice coil actuators (VCA) are non-commutated DC linear actuators that consist of a single-pole permanent magnet and a copper coil. VCMs are two-lead, single phase motors that do not require commutation, resulting in simple operation.

What are the 4 essential parts of camera?

Who makes Apple cameras?

Apple is known for good cameras inside its iPhones but the sensors are supplied by Sony. It was about time that Apple would have its own in-house camera hardware as well. To make that a reality, Apple has acquired an Israel-based camera technology company called LinX Computational Imaging Limited.
