Abstract

A projection system comprises a projector main body and an infrared pen, wherein the projector main body comprises a photographing device, a file input interface, a file processor, a memory, a signal receiver and an image processor, wherein the file input interface is connected with data storage equipment in which a to-be-projected file is stored; the file processor displays the to-be-projected file; the infrared pen gives out operation instruction signals for operating on a projection picture, and the operation instruction signals form an infrared track on the projection picture; the signal receiver is used for receiving the operation instruction signals; the photographing device is used for photographing an image of the projection picture with the operation instruction signals and transmitting the image to the image processor; the memory stores multiple preset instruction pictures; the image processor is used for processing and acquiring the operation instruction sent by the infrared pen and sending the current operation instruction to the file processor; and the file processor executes the operation instruction.

Description

technical field [0001] The invention relates to multimedia technology, in particular to a projection system and a projection method. Background technique [0002] Multimedia technology is the fastest growing and most active technology in today's information technology field, and it is the focus of the development and competition of the new generation of electronic technology. Multimedia technology integrates multiple functions such as computer, sound, text, image, animation, video and communication. With the help of the increasingly popular high-speed information network, global networking of computers and sharing of information resources can be realized. However, in terms of product composition, multimedia The equipment used needs to be connected to a computer, mouse, monitor and other equipment. As a result, the structure of the projection system is complex and bulky. Contents of the invention [0003] In view of this, it is necessary to provide a projection system and...
