Problems solved by technology

However, there may be many kinds of light sources in the projection site, such as outdoors or indoors with dim light, the projection effect will be different in different environments
Moreover, usually the background of the projection needs to be white to clearly display the content, but not all places are equipped with a white screen for projection, at this time, the projection effect will be greatly weakened

Embodiment Construction

[0014] see figure 1 , is a hardware architecture diagram of a mobile terminal with a pico projector according to the first embodiment of the present invention. The mobile terminal 10 with a micro-projector includes a projector 110 , a camera 120 , a processing unit 130 , a light source driver 140 and a projection light source 150 .

[0015] The camera 120 is used for sensing the light source type and brightness information of the projection environment. Specifically, the camera 120 can sense the type of light source in the shooting place, such as sunlight, incandescent lamp, fluorescent lamp, and the like. The camera 120 can also use a brightness sensor inside the camera 120 to detect the brightness information of the projection environment.

[0016] The processing unit 130 is configured to perform white balance reverse processing on the content to be projected according to the light source type of the projection environment, that is, reversely apply the white balance functi...

Abstract

The invention relates to a mobile terminal with a miniature projector and a projection method. The mobile terminal comprises a projection light source which is used for providing a light source for the projector, and the projector. The mobile terminal also comprises a camera used for obtaining external environment information, a processing unit used for adjusting contents to be projected based on the external environment information, and the projector used for projecting the contents to be projected adjusted by the processing unit based on the output of the projection light source. According to the mobile terminal with the miniature projector and the projection method, the external environment information is obtained by utilizing the camera, and projection output is changed correspondingly, so that the projection effect is enhanced.

Description

technical field [0001] The invention relates to a mobile terminal with a micro-projector and a projection method, in particular to a mobile terminal with a micro-projector and a projection method that changes the projection output according to the external environment. Background technique [0002] Use handheld mobile devices for projection, so that users can modify and view projected content anytime and anywhere. However, there may be many kinds of light sources in the projection site, such as outdoors or indoors under dim light, and the projection effect will be different in different environments. Moreover, usually the background of projection needs to be white to clearly display the content, but not all places are equipped with white screens for projection, at this time, the projection effect will be greatly weakened. Contents of the invention [0003] The invention provides a mobile terminal with a micro-projector and a projection method for changing the projection o...
