In the process of using the projector, except for those fixedly installed projectors, there is basically no need to adjust them.The home projectors that are put away due to space constraints need to manually adjust the screen before each use. And focus. It takes time and effort to say, sometimes it may not be possible to adjust to the best picture, or it may not be clear how to adjust it. At this time, I very much hope that the projector screen can be quickly and automatically corrected and focused, there is no need to manually adjust, TOF is the function that was born.
TOF stands for Time of Flight. Literal translation means time of flight. In actual use, it is often referred to as time-of-flight ranging method, which mainly uses the time of flight between the two transceivers to measure the distance between two points. After using this technology, the projector can calculate the actual focal length from the distance between the machine and the wall, and then autofocus.
Dangbei F1C and Dangbei projector F3 are equipped with dual TOF + CMOS camera module, after the rapid focusing of dual TOF, through the CMOS camera for secondary correction, and can also automatically adjust the angle of the screen to complete the automatic trapezoid correction , No need to manually adjust to make the picture clear and square.
In this way, even newbies can easily play with the projector. No need to make additional manual adjustments. Every time you just turn on the projector, you can automatically adjust the picture.
Dangbei Projector F3 is a new product launched by Dangbei on April 24, 2020. It adopts dual TOF + CMOS camera modules, and has the functions of sensorless autofocus and sensorless automatic keystone correction. Through two miniature time-of-flight sensors TOF, continuous invisible light pulses of 940 nanometers are sent. After receiving the returned light pulses, the sensor calculates precisely and realizes fast and non-sense focusing.
