Problems solved by technology

[0002] The all-in-one projection computer in the prior art requires a larger space for heat dissipation and space for placing internal components of the computer, so it usually has a large volume, which makes the all-in-one projection computer unsuitable for all environments. It will take up a lot of space when placed on the table, and it will also block the view of the audience watching the projection, affecting the viewing effect
[0003] The problem in the prior art is: the projection module will directly project the object to be displayed into the preset projection area, even if there is an obstacle in the projection area, the projection module will still project the object to be displayed to the obstacle , and this will obviously affect the projection effect, which is not conducive to users watching

Embodiment 1

[0057] The electronic device is placed on the first edge of the table. The electronic device includes a housing 201 and a main body 202. The main body 202 includes a projection module 2021 and an imaging lens 2022. The electronic device also includes an input device 203. 203 is provided separately from the electronic device. The user is located on the second edge of the table opposite to the first edge, and the input device 203 is located on the user side. When projection is needed, the detection module 101 detects that there is no obstacle in the first projection area, and the first control module 102 controls the electronic device to perform projection in the first projection mode, that is, controls the projection module In 2021, the object to be displayed is projected in the first projection area through the imaging lens 2022.

Embodiment 2

[0059] The electronic device is placed on the first edge of the table. The electronic device includes a housing 201 and a main body 202. The main body 202 includes a projection module 2021 and an imaging lens 2022. The electronic device also includes an input device 203. 203 is not separated from the electronic device, and the input device 203 is located on the upper end surface of the housing 201 close to the rear end of the housing 201. When projection is required, the detection module 101 detects that there is an obstacle in the first projection area. In the embodiment of the present invention, the obstacle is one placed on the supporting surface for supporting the electronic device. Cup, the supporting surface in the embodiment of the present invention is a desktop. Then the second control module 103 controls the electronic device to perform projection in the second projection mode according to the detection result of the detection module 101, that is, controls the projecti...

Embodiment 3

[0061] The first stage: The electronic device is placed on the first edge of the table. The electronic device includes a housing 201 and a main body 202. The main body 202 includes a projection module 2021 and an imaging lens 2022. The electronic device also includes an input device 203 The input device 203 is not separated from the electronic device, and the input device 203 is located on the upper end surface of the housing 201 close to the rear end of the housing 201. When projection is needed, the detection module 101 detects that there is no obstacle in the first projection area, and the first control module 102 controls the electronic device to perform projection in the first projection mode, that is, controls the projection module In 2021, the object to be displayed is projected in the first projection area through the imaging lens 2022.

[0062] The second stage: during the projection process, a user stands in the first projection area, and the detection module 101 detect...

Abstract

The invention discloses a projection method used for improving projection quality. The method includes the steps of detecting whether a barrier exists in a first projection area or not, generating a detection result, controlling the projection to be conducted in a first projection mode when the detection result shows that the barrier does not exist in the first projection area, and controlling the projection to be conducted in a second projection mode when the detection result shows that the barrier exists in the first projection area, wherein the first projection mode is that a projection module projects an object to be displayed on the first projection area through an imaging lens, and the second projection mode enables an image, formed on a projection carrier, of the object to be displayed not to be influenced by the barrier. The invention further discloses an electronic device for achieving the method.

Description

Technical field [0001] The present invention relates to the field of computer and projection technology, in particular to a projection method and electronic equipment. Background technique [0002] In the prior art, the all-in-one projection computer requires a larger space for heat dissipation and space for placing the internal components of the computer, so it is usually large in size, which makes the all-in-one projection computer not suitable for all environments. When placed on the table, it will take up a lot of space, and will also block the sight of the audience watching the projection, which will affect the viewing effect. [0003] The problem in the prior art is that the projection module will directly project the object to be displayed into the preset projection area. Even if there is an obstacle in the projection area, the projection module will still project the object to be displayed onto the obstacle. However, this will obviously affect the projection effect and is ...
