ViewSonic Launches ToF Technology to its Latest Portable LED Projector M2e to achieve Instant Auto Focus
ToF technology allows the M2e to instantly autofocus in only one second, which is 3-5 times faster in comparison with current methods. It provides impeccable optical precision, effortless setup, and its portability makes for flexible entertainment and works at home.
FREMONT, CA: ViewSonic Corporation, a leading global provider of visual solutions, is launching its latest M2e Instant Smart 1080p Portable LED Projector. This new addition to the company's M series of smart portable LED projectors utilizes Time-of-Flight (ToF) technology to get instant autofocus in an ultralight and portable design. ToF technology allows the M2e to instantly autofocus in only one second, which is 3-5 times faster in comparison with current methods. It provides impeccable optical precision, effortless setup, and its portability makes for flexible entertainment and works at home.
"ViewSonic is an industry-leading manufacturer in visual technology, constantly dedicated to innovating and upgrading LED projectors, making them smarter, easier to use, and thus enhancing the user experience," stated Dean Tsai, Head of the Projector BU at ViewSonic. "By applying ToF technology, we have reached a new milestone with the launch of the M2e, which fulfills carefree usage at home. As people now tend to stay at home more often, the new M2e allows them to enjoy an unprecedented audiovisual feast and the precious moments with family instantly and effortlessly."
Instant Auto Focus with ToF Technology
ToF sensors are a type of scanner-less LIDAR (light detection and ranging) technology that measures distance depending on the time it takes for photons to travel between the sensor's emitter and the target area, allowing for accurate distance ranging irrespective of the object's surface characteristics. They also have high-accuracy linearity as well as up to 3m detection range with a full field of view.
Traditionally, when a projector is moved, it requires to be refocused by either a press on the remote control to trigger autofocus or manual adjustments on the focus ring. The M2e can detect changes in the setup position with the built-in G sensor design and activate instant autofocus automatically using ToF technology. Not only is the focusing more effective, but it can be done in only one second, which is 3-5 times faster than the usual autofocus that uses a camera to capture and fit continuous images, not to mention those changed by manual focus ring adjustment.
