Image display method, storage medium and system thereof

Abstract

The present invention provides an image display method and its storage medium and system, comprising step 1: generating a plurality of sub-images according to an input image, wherein the plurality of sub-images respectively record part of the input image; further comprising step 2: Displaying the multiple sub-images at different times, or step 2': displaying the multiple sub-images at different times and generating corresponding holograms or kinographs through mathematical transformation. The invention solves the problem of laser speckle caused by mutual interference between pixels through a software method, can be used alone, does not need to add additional hardware, and can reduce costs. Of course, it can also be combined with other speckle dissipating technologies to enhance the speckle dissipating effect. Applicable to all laser imaging systems, including holographic display technologies using coherent 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
