Embodiment Construction

[0046] see figure 1 , figure 1 It is a flow chart of the image display method provided by the present invention in the first embodiment. The image display method can be applied to image display devices and projection equipment including the image display device, such as cinema machines, laser TVs, engineering machines, business education machines, video walls, and micro-projection equipment.

[0047] The image display method of this embodiment is applicable, and the image display device may include a first light source and a second light source, so as to provide specific brightness through the cooperation of the first light source and the second light source. Such as figure 1 As shown, the image display method in this embodiment may include the following steps:

[0048] S101: Acquire image information of an image frame to be displayed that currently includes multiple display partitions.

[0049] In this embodiment, the display partition is a partition obtained by dividing ...

Abstract

The invention relates to an image display method and apparatus, and a projection device. The image display method comprises the steps of obtaining image information of a to-be-displayed image frame comprising a plurality of display partitions at present; adjusting the brightness of a first light source with a first light field according to the image information of the current to-be-displayed imageframe, and performing light guiding on a second light source to form a second light field, and the first light field provided by the first light source is matched with the second light field providedby the second light source, so that the display requirement of each display subarea of the to-be-displayed image frame can be met. According to the invention, high dynamic range display of images can be realized, and dark field detail expression of the to-be-displayed image can be improved.

Description

technical field [0001] The present invention relates to the field of projection technology, in particular to an image display method, device and projection equipment. Background technique [0002] In the application technology of projection equipment to realize high dynamic range display, if there is a technical solution: use part of the light for light-guided high dynamic range display projection equipment, 70% of the light from the light source is directly provided to the digital micromirror spatial light modulator , and 30% of the light is provided to the silicon-based liquid crystal chip for light guidance and then illuminates the digital micromirror spatial light modulator, thereby increasing the local brightness of the projected image. This technology can improve the peak brightness of the projected image and increase the color gradation and brightness of the bright field part. However, the dark field of the projected image is still bright, and the details of the dark ...
