Abstract

The invention provides projection equipment, comprising a signal input unit which is used for receiving a video signal generated by a video source, a signal output unit which is used for transmittingthe video signal received by the signal input unit to a signal image processing unit, a signal image processing unit which is used for receiving the video signal transmitted by the signal output unitand carrying out image processing and projection display on the video signal, and a signal output unit which is also used for processing the video signal received by the signal input unit and outputting the processed video signal as an input signal of a signal input unit of another projection device. The invention further provides a projection system and a projection method. Compared with the prior art, the projection equipment, the projection system and the projection method are low in cost and convenient to use.

Description

technical field [0001] The present invention relates to the technical field of light and shadow display, in particular to a projection device, a projection system and a projection method. Background technique [0002] With the development of the intelligent era, light and shadow display has become a development trend and has been used in more and more fields, such as projection equipment, especially in large-scale exhibitions, conferences, and teaching. [0003] In some special occasions, such as product exhibitions, large conference rooms or auditoriums, multiple display screens (projection) are required, and the same content needs to be displayed synchronously. For example, large lectures require display screens in different positions to display the same content. [0004] Among the projection devices of the related art, the external VGA signal splitter is widely used to realize one input and multiple outputs. However, on the one hand, this method will increase a certain c...
