Abstract

The invention provides a method and a device for multi-channel digital division. The method includes: (1) generating a group of corresponding gray-scale images and color images respectively according to each digital image in a plurality of digital images; (2) building a pixel screen; (3) deleting a part of pixels in the gray-scale images and the color images according to the pixel screen; and (4) combining the plurality of pixel-deleted gray-scale images obtained in the step (3) into a synthesized gray-scale image, and combining the plurality of pixel-deleted color images obtained in the step (3) into a synthesized color image. The method and the device can increase luminance area of each exposure field to the largest extent and enable diffraction efficiency of each exposure field to be the best during multi-channel filming.

Description

technical field [0001] The invention relates to the field of holographic imaging, and in particular to a multi-channel digital segmentation method and device. Background technique [0002] Holographic technology is a technology that uses the principle of interference and diffraction to record and reproduce the real three-dimensional image of an object. It can be divided into the following two processes: [0003] (1) Hologram generation process: Use the principle of interference to record the light wave information of the object, use a part of the laser to irradiate the object to form a diffuse object beam, and the other part of the laser is used as a reference beam to shoot on the holographic film to match the object. The beam superposition produces interference, which converts the phase and amplitude of each point on the object light wave into a spatially varying intensity, so that all information of the object light wave can be recorded by using the contrast and interval b...
