Embodiment Construction

[0013] Such as figure 1 Shown is a schematic diagram of the operating environment of a preferred embodiment of the projection system of the present invention. The first electronic device 1 communicates with the second electronic device 2 through wired or wireless communication, and the first electronic device 1 may include a first memory 12 , a processor 14 , a camera 16 , and a first projection device 18 . The second electronic device 2 includes a second projection device 20 and a second memory 22 .

[0014] The first electronic device 1 and the second electronic device 2 may be electronic devices such as mobile phones, tablet computers or personal digital assistants.

[0015] The first memory 12 is used to store data such as program codes of the projection system 10 .

[0016] The second memory 22 is used for storing image data such as the image 4 on the second electronic device 2 .

[0017] The first projection device 18 is integrated in the first electronic device 1, an...

Abstract

Provided are a projection method and system. The method comprises the steps that a first projection device enables a screen picture of a first electronic device to be projected to be a display screen; when a second projection device projects an image, a camera device is triggered to shoot a display-screen picture; the shot display-screen picture is obtained from the camera device; when the image exists in the display-screen picture, the position, the size and the gradient of the image on the display screen are identified; a second electronic device is notified to transmit the image to the first electronic device; the image is processed in the first electronic device, the image conforms to the size, the position and the gradient of the image on the display-screen picture when being projected to the display screen, the size, the position and the gradient of the image on the display-screen picture are obtained from the camera device in an identified mode, and an integral picture is formed by the processed image and the screen picture belonging to the first electronic device on the display-screen picture shot by the camera device; the obtained integral picture is projected to the display screen. The projection method and system achieve the fact that the electronic devices achieve interaction of information of the electronic devices through the same projection display screen.

Description

technical field [0001] The invention relates to a projection method and system. Background technique [0002] With the development of projection technology, the projection technology is embedded in electronic devices, especially in mobile phones. After the mobile phone is embedded with projection technology, the operating screen will change from a small screen on the fuselage to a large screen formed by projection. However, the existing technology can only project the screen on the user's own electronic device onto the screen, and cannot realize the interaction of multiple user information through the screen. Contents of the invention [0003] In view of the above, it is necessary to provide a projection method and system to realize the interaction of multiple user information through one projection screen. [0004] The present invention provides a projection method, which includes a first projection step, the first projection device projects the picture displayed on the...
