Image display method, storage medium thereof and image display system

Abstract

The invention provides an image display method, a storage medium thereof, and an image display system. The method includes a step 1 of: generating a plurality of sub-images according to an input image, wherein the plurality of sub-images record a part of the content of the input image respectively; and a step 2 of displaying the plurality of sub-images at different times respectively, or a step 2'of displaying corresponding holograms or kinoforms generated from the plurality of sub-images through mathematical transformation at different times respectively. The method solves laser speckles caused by mutual interference between pixels by software, and can be used independently without additional hardware, and can reduce the cost. Of course, the method can be combined with other speckle-eliminating techniques to enhance a speckle-eliminating effect. The method is suitable for all laser imaging systems, including holographic display technology using coherence imaging.

Description

technical field [0001] The present invention relates to the field of laser imaging, in particular to an image display method, storage medium and system thereof. Background technique [0002] As a light source, laser has the advantages of high brightness, long life, wide color gamut, etc., and has been widely used in the display field in recent years. The current speckle elimination methods are mostly achieved by eliminating the coherence of the laser, adding a decoherence device in the display system or adding a vibrating component in the optical path to homogenize the speckle. But the problem is that special hardware is added to realize the speckle dissipation function, which increases the cost, increases the complexity of the system, and the effect is also limited. Furthermore, for some technologies that utilize laser coherence imaging (eg holographic displays) such speckle removal methods will affect the imaging. [0003] For this reason, technicians have made great eff...

Problems solved by technology

[0004] However, the patent document CN105301792A does not completely eliminate speckle. The reason is that, as a coherent light source, due to the coherence of the secondary wavelet on the display surface, it is easy to cause mutual interference between pixels, and laser speckle will still be formed to affect imaging. quality

Even if there is only one laser light source, although the coherent interference between different light sources is overcome, this laser light source will still interfere with each other between adjacent pixels
