Image sensing module and image capture module

Abstract

The invention provides an image sensing module, which comprises an image sensing chip and a first transparent substrate fully covering the image sensing chip. The image sensing module further comprises a second transparent substrate and a liquid crystal layer which consists of liquid crystal molecules and is positioned between the first transparent substrate and the second transparent substrate; the first transparent substrate and the second transparent substrate are respectively provided with a first electrode layer and a second electrode layer for applying an electric field to the liquid crystal layer, so that the liquid crystal molecules rotates in different angles and have different refractive indexes; and light enters the image sensing chip through the liquid crystal element. The first electrode layer and the second electrode layer all include round electrodes, first ring electrodes, second ring electrodes, third ring electrodes and fourth electrodes concentric with the round electrodes, wherein the radius of the round electrode is r1, ring widths of the first ring electrodes, the second ring electrodes, the third ring electrodes and the fourth ring electrodes are respectively d2, d3, d4 and d5, and r1>d2>d3>d4>d5.

Description

technical field [0001] The invention relates to an image sensing module and an image capturing module. Background technique [0002] When shooting two objects at a certain distance before and after the process, when the lens focuses on one of the objects, a clear image of the object can be obtained, and the image of the other object is relatively blurred. In order to obtain a clear image of the two objects (also called an all-focused image), the lens is combined with digital computing image processing (Computational photography) technology for post-processing. [0003] The lens of this structure needs to add additional optical elements that will cause the loss of light transmittance, such as coded aperture (Coded aperture), mask (Mask), etc., mainly rely on the processing of these optical elements to obtain the images of the front and rear objects, and then The image is processed with a little digital calculation to obtain a clear image. Since the structure mainly relies on...

[0003] The lens of this structure needs to add additional optical elements that will cause the loss of light transmittance, such as coded aperture (Coded aperture), mask (Mask), etc., mainly rely on the processing of these optical elements to obtain the images of the front and rear objects, and then The image is processed with a little digital calculation to obtain a clear image. Since the structure mainly relies on optical elements, the production cost is high; and if the wavefront optical element (Wavefront optical element) and phase plate ( phase plate), optical diffraction components, and micro-lens, etc. will cause an increase in the amount of calculations for digital computing and image processing
