Problems solved by technology

[0004] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the above related technologies: the projection device that improves the resolution based on the vibration of the galvanometer will have the disadvantage of increasing the noise of the projected image, and when the projection output resolution is lower than or equal to the projection display When the image with the physical resolution of the chip is used, the vibrating lens cannot improve the resolution of the projected image very well. On the contrary, due to the increase of noise generated by the vibrating lens or the influence of image difference, it will interfere with the projection quality and reduce the user's vision. to feel

Abstract

The invention relates to a galvanometer adjusting device, a system and method and a projector in the technical field of projection display. The galvanometer adjusting device comprises an image featureacquisition module, an image judgment module, a resolution extraction module and a galvanometer control module. The galvanometer adjusting device judges the type of the projection image and the corresponding resolution information according to the acquired information characteristics of the projection image; therefore, whether the galvanometer needs to be started for vibration or not is judged toimprove the image resolution, the on-off state of the galvanometer is intelligently and automatically controlled correspondingly to achieve the optimal projection display effect, and the visual enjoyment of a user is greatly improved.

Description

technical field [0001] The invention relates to the technical field of projection display, in particular to a vibrating mirror adjustment device, system, method and projector. Background technique [0002] With the improvement of science and technology, projection imaging equipment is more and more widely used in people's work and life. The higher the resolution of projection imaging equipment, the higher the viewing experience of users. Image resolution is a major indicator of image quality, the higher the image resolution, the closer it is to the real scene. Improving image resolution is mainly through improving hardware equipment and image processing software. The way to improve hardware equipment is mainly to improve image imaging components and optical systems. [0003] In the prior art, vibrating mirrors (referred to as vibrating mirrors) are routinely used to improve resolution. Usually, the original single or combined key components in the optical system are improve...
