Description
Technical field
The present invention relates to electric quantity monitoring field more particularly to a kind of projection triggering methods based on electric quantity monitoring.
Background technique
Projection refers to that the shape of object is projected a plane up with one group of light, referred to as " projects ".It is flat at this
The image obtained on face also referred to as " projects ".Projection can be divided into orthographic projection and oblique projection.Orthographic projection is the center line of the incident line
Perpendicular to the plane of projection, center of projection line is not orthogonal to the referred to as oblique projection of projection plane.
It is exactly central projection that object, which forms shadow under the light irradiation that light bulb issues,.A kind of present projection display system sRGB
That Microsoft develops cooperatively with Seiko Epson company, Mitsubishi, it is therefore an objective to establish one can satisfy computer and
The color management standard of Projection Display demand, so that display equipment is analyzed without special color information, so that it may correct
Ground shows image file.
Currently, although projection is lower to the eye injury degree of user, user watches the major way of display content still
Screen is shown, if the opportunity that content of the selection from display screen to projection device switches, to realize to the anti-of the eyes of user
Shield, is one of still unsolved problem.
Summary of the invention
To solve the above-mentioned problems, the projection triggering method based on electric quantity monitoring that the present invention provides a kind of, can be based on
The font size of display screen present displayed content decides whether to project, so that mobile phone user be avoided to watch on mobile phone display screen
Too small font more crucially also introduces targeted electric power detection mechanism and image recognition mechanism, to improve
Availability of the invention.
According to an aspect of the present invention, a kind of projection triggering method based on electric quantity monitoring is provided, the method includes
