Abstract

The invention relates to a method for switching the working mode of a projection device, which includes collecting the sampling value of the acceleration of gravity of the projection device according to a preset sampling period; The gravitational acceleration value of the projection device; when it is determined that the projection device changes from a motion state to a static state according to the gravitational acceleration value of the projection device at a preset time interval, obtain the current gravitational acceleration value of the projection device; according to the current gravitational acceleration value , the default gravitational acceleration direction of the projection device and the current working mode of the projection device to determine whether to switch the working module of the projection device. The present invention can quickly and conveniently switch the working mode of the projection device, can reduce erroneous switching caused by misjudgment, and improves user experience. The invention also relates to a device for switching the working mode of the projection equipment and the projection equipment.

Description

technical field [0001] The invention relates to the field of projection equipment, in particular to a method and device for switching the working mode of the projection equipment and the projection equipment. Background technique [0002] Compared with traditional projectors, micro-projectors have exquisite and portable functions, so they are more and more widely used in business office and teaching and training fields. With the rapid development of computer software and hardware technology, micro projectors have also begun to develop features with different functions to meet the new needs of work, study and daily life. At present, micro-projectors generally include two working modes: projection mode and sound mode. The existing switching method is usually by operating physical buttons. How to provide a projector that can quickly and conveniently switch between projection mode and sound mode? , no effective solution has been proposed so far. Contents of the invention [...
