Embodiment Construction

[0019] The projection method in the embodiment of the present invention is to collect parameter information related to the projection effect corresponding to the projection area when the projection content needs to be projected into the projection area; based on the parameter information, it is judged whether the projection content needs to be Adjusting: when the projection content needs to be adjusted, adjusting the projection content based on the parameter information to obtain adjusted projection content; projecting the adjusted projection content into the projection area. Adjust the projection content according to the corresponding parameter information of the projection area, and then project the adjusted projection content to the projection area, so that the projection content can be displayed more clearly in the projection area, which is convenient for users to watch and improves the projection effect.

Abstract

The invention discloses a projection method used for improving projection effects. The projection method comprises the steps of: when a projection content needs to be projected in a projection region, collecting parameter information having relationship with the projection effect of the corresponding projection region; judging if adjustment for the projection content is necessary based on the parameter information; and adjusting the projection content based on the parameter information when the adjustment for the projection content is necessary, and obtaining the adjusted projection content; and projecting the adjusted projection content within the projection region. The invention also discloses a device for realizing the method.

Description

technical field [0001] The invention relates to the technical field of computer and projection, in particular to a projection method and device. Background technique [0002] The big trouble when using small-scale projection technology is that the projection position is not very ideal. Sometimes the projection position may be a relatively complex projection surface, and the reflectivity of the projection surface may be different at different places, or the projection surface may have various shapes ,multiple colour. [0003] In the process of implementing the technical solutions of the embodiments of the present application, the inventors of the present application at least found the following technical problems in the prior art: [0004] Projectors project indiscriminately regardless of projection location, which obviously affects the display. Contents of the invention [0005] Embodiments of the present invention provide a projection method and device for improving pro...
