Problems solved by technology

However, due to the light intensity of the on-site projection environment, the projection effect is often unsatisfactory, and users cannot clearly or easily obtain the projected content, resulting in poor user experience
[0003] In view of this situation, by presetting multiple brightness levels in the adjustment menu of the projector for users to choose, users can manually adjust according to the site environment, or use the device to collect ambient light for automatic brightness adjustment. However, the above two These adjustment methods are all through changing a parameter of the projection brightness of the projector. For the projection effect, only changing one of the parameters of the brightness will cause the white balance of the projector light machine to change, which will cause the brightness of different gears to appear. Color deviation, it is difficult to meet the increasingly high requirements of users

Embodiment 1

[0053] refer to figure 1 , an embodiment of the present invention provides a projection adjustment method, which includes the steps of:

[0054] S10. Obtain the light intensity information of the current projection environment; the light intensity information of the current projection environment can be obtained through the light sensor. In order to better cope with different application scenarios, more light sensors can be set according to actual needs to obtain the current light intensity information to improve the accuracy of obtaining light intensity information.

[0055] S20. Obtain the corresponding projection mode according to the light intensity information; after obtaining the light intensity information, obtain the stored projection mode corresponding to different light intensity information according to the light intensity information, and set multiple different projection modes corresponding to different light intensities information. For example, the light inten...

Embodiment 2

[0061] On the basis of Embodiment 1, in order to prevent the short-term fluctuation of projection parameters in the light intensity information of the projection environment in a small range, resulting in continuous switching of projection modes and affecting the user experience, the corresponding projection mode is acquired according to the light intensity information The anti-shake process is added before.

[0062] Specifically, refer to figure 2 , the anti-shake process specifically includes:

[0063] Judging whether the number of times n to obtain light intensity information is greater than the preset number of sampling times, where the preset number of sampling times can be set to a specific value according to different usage requirements, when n is not greater than the preset number of sampling times, then after delaying the preset time Continue to obtain the light intensity information of the current projection environment, and delay the preset time before continuing ...

Embodiment 3

[0068] refer to image 3 , an embodiment of the present invention provides a projection adjustment device, which includes:

[0069] The environment information obtaining module is used to obtain the light intensity information of the current projection environment;

[0070] The selection module is used to obtain the corresponding projection mode according to the light intensity information;

[0071] The preset projection parameter key value acquisition module is used to extract the preset projection parameter key value corresponding to the projection mode;

[0072] A parameter acquisition module, configured to acquire corresponding brightness value parameters and / or white balance values ​​and / or screen contrast values ​​and / or screen saturation values ​​according to preset projection parameter key values;

[0073] The parameter adjustment module is used for adjusting the current projected image according to the brightness value parameter and / or the white balance value and / or...

Abstract

The invention discloses a projection adjustment method, device, projector and system, wherein the projection adjustment method acquires the light intensity information of the current projection environment, obtains the corresponding projection mode according to the light intensity information, and then extracts the corresponding preset projection parameter key value, and then obtain the corresponding brightness value parameter and / or white balance value parameter and / or contrast key value parameter and / or saturation value parameter according to the preset projection parameter key value, and finally adjust the current projected image according to the obtained parameters; solved In the prior art, the projector only adjusts one parameter of projection brightness. For the projection effect, color deviation occurs in the brightness of different gears, which is difficult to meet the increasing requirements of users; it provides an adaptive, accurate A projection adjustment method with a good user experience.

Description

technical field [0001] The present invention relates to the field of projection technology, in particular to a projection adjustment method, device, projector and projection system. Background technique [0002] With the continuous development of projection technology, various types of conferences, speeches, performances and other activities have adopted projection technology, so that participants can easily and time-saving express the content that needs to be displayed or obtain the projected content, for people's work, Entertainment and other aspects provide great convenience. However, due to the influence of the light intensity of the on-site projection environment, the projection effect is often unsatisfactory, and the user cannot clearly or easily obtain the projected content, resulting in a bad user experience for the user. [0003] In view of this situation, by presetting multiple brightness levels in the adjustment menu of the projector for users to choose, users ca...
