Embodiment Construction

[0051] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] For the existing light valves, take a DLP projector as an example, the DLP projector mainly performs digital processing on the image signal before projection. In a DLP projector, the light source passes through a color wheel with three primary colors. In a laser light source, the color wheel usually corresponds to the two color wheels of the fluorescent wheel and the color filter wheel, and the light beam follows the three primary...

Abstract

The invention discloses a projected image processing method, and device and a projection display system. The scheme disclosed by the invention comprises the following steps: acquiring a to-be-projected image, dividing the to-be-projected image into N frame images, wherein the resolution of each of N frame images is the second resolution, the resolution of the to-be-projected image is the first resolution, the second resolution is not more than the resolution of the light valve, and N is a positive integer greater than 1; and displaying N frame images in an active shutter 3D system way. Visually, the scheme disclosed by the invention divides the high-resolution image to obtain N frame images with resolution less than or equal to the resolution of the light valve, the N frame images are displayed in the active shutter 3D system way; since the sum of the information amount contained by the N frame images is the same as the information amount of the to-be-projected image, the information amount of the image is substantially free from loss, the defect that the pixel information is lost when the high-resolution image is displayed through the projection in the prior art is overcome, the pixel information amount carried in the high-resolution image can be retained when the high-resolution image is displayed through the projection.

Description

technical field [0001] The present invention relates to the projection field, in particular to a projection image processing method, device and projection display system. Background technique [0002] The resolution of an image represents the amount of information stored in the image, and is usually represented by the product of the number of pixels in the image in the row direction and the number of pixels in the column direction, that is, the total number of pixels. The higher the resolution of an image, the more pixels the image contains and the clearer the image. For example, an image with a resolution of 1920×1080 indicates an information volume of 2M pixels, and an image with a resolution of 3840×2160 indicates an information volume of 8M pixels. [0003] In the projection display device, the resolution of the light valve of the light modulation element in the light machine determines the resolution of the display device of the entire projection device to a large exte...
