Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] When projecting, users often require the projected images to have high quality and contrast, so as to obtain comfortable high-quality projection effects. Corresponding to dynamic images, when the light-to-dark conversion is relatively fast, the higher the contrast, the easier it is for the human eye to distinguish such a conversion process, thus bringing users a realistic visual experience. However, projection equipment often has a mutually restrictive relationship between brightness and contrast. When a projection equipment has high brightness, it will also be accompanied by more stray ligh...

Abstract

Embodiments of the present invention relate to the field of projection technologies, and in particular, to a projection method and projection equipment. Wherein, the projection method includes: acquiring a projection image and an environment image when the projection area is projected, wherein the environment image includes an image when the projection area is projected with a preset projection screen or an image when the projection area is not projected; according to the projection image and the environment Image, adjust the aperture, which is used to control the amount of light projected to the projection area. Therefore, by adjusting the aperture, it can reduce the influence of stray light, and effectively coordinate the relationship between projection contrast and brightness, so that projection contrast and brightness can be effectively balanced, thereby improving projection quality.

Description

technical field [0001] Embodiments of the present invention relate to the field of projection technologies, and in particular, to a projection method and projection equipment. Background technique [0002] With the development of computer multimedia display technology, the projector, as a better large-screen display device, has gradually become a standard computer peripheral product, and can be widely used in various industries such as education and business. [0003] When projecting, due to the influence of stray light from the optical system of the projector, the projection quality of the existing projected picture is relatively poor. Contents of the invention [0004] An object of an embodiment of the present invention is to provide a projection method and a projection device, which can reduce the influence of stray light. [0005] In order to solve the above technical problems, embodiments of the present invention provide the following technical solutions: [0006] I...
