What is VCM in camera module?
Voice Coil Motors (VCM), also called Voice Coil Actuators (VCA), are a very mature design that utilizes a magnet and yoke in conjunction with a coil. Because the coil is the only moving component, they allow for both high-speed motion and accurate positioning. It’s typically used as the camera’s focus function.
What is TLens?
The TLens (Tunable Lens) doesn’t just replace traditional VCM technology for autofocus. Instead it enables a range of entirely new experiences, use cases, and ways to build innovation and help you differentiate.
Which company camera does Samsung use?
Samsung Electro-Mechanics is the only company that holds all of the core technologies necessary to design and manufacture world-class camera modules based on the internalization of lens, actuator, and PKG technology.
What is VCM driver?
The BU64985GWZ is designed to drive Bi-directional voice coil motors. The drivers include ISRC (intelligent slew rate control) to reduce mechanical ringing to optimize the camera’s autofocus capabilities. …
Do cell phone cameras have actuators?
Among existing AF actuators, the miniature VCM actuators have been widely used into cell phone camera modules due to its low cost, small volume, robust performance, easy implementation, and high productivity characteristics [3] [4] [5]. …
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. These motors are most commonly used for short travel paths where high acceleration and constant force is required.
What is tunable lens?
Focal Length Tuning Strategies An electrically tunable lens, or “smart lens”, is here defined as a light focusing medium (in the form of either a fluid, a gel or a solid) that is able to use an input electrical energy to dynamically modulate its focal length.
Who makes camera for Apple?
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.
What is phone module?
A modular smartphone is a smartphone made using components that can be independently upgraded or replaced as modules. This aims to reduce electronic waste, lower repair costs and increase user comfort. The most important component is the main board, to which others (such as cameras or batteries) are attached.
How does a camera module works?
After the external light passes through the Lens, it is filtered by the IR Filter and then irradiated onto the Sensor surface. The Sensor converts the light from the Lens into an electrical signal, and then converts it into a digital signal through internal A/D.
What is a camera module?
Camera module is a genuine imitation of human eye. Basically, it consists of a lens, a holder, a voice coil motor (VCM), an infrared ray (IR) filter, a sensor and a flexible printed circuit (FPC). Let’s debrief them so you can know better what they are: Lens: lens is a key part of the camera module.
What is the difference between packaged tlens ® and VCM?
More efficient AF camera module manufacturing – the Packaged TLens ® will enable efficient manufacturing of camera modules, resulting in better yield at camera module level. The Packaged TLens ® minimises dust contamination, whereas VCM keeps open access to the image sensor.
What are the limitations of a camera module?
In addition, there are severe power-consumption restrictions on camera modules: a camera module that eats significantly into talk time will never be a success. A lens driver controls the actuator that moves the lens assembly back and forth to adjust focus and/or magnification in camera phones with resolutions typically greater than two megapixels.
Can This autofocus camera module be used with a UVC controller?
This autofocus camera module can be used with any Application Processors or Digital Signal/Media Processors or even with USB UVC controllers with a compatible camera interface. 1. PC Solution
