Pixel structure unit, lens module, electronic equipment and shadow elimination method

Abstract

The invention discloses a pixel structure unit. The pixel structure unit comprises a sub-pixel array; an optical filter array is arranged on the sub-pixel array; a micro lens is arranged on the optical filter array, the micro lens has the characteristic of electrochromism, and the light transmittance of the micro lens is gradually increased from a center pixel to an edge pixel. Therefore, the shadow phenomenon in lens imaging can be eliminated without using an algorithm, so that the image processing speed of the optical sensor is not influenced, the storage resource of camera equipment is not occupied, the imaging frame rate is not reduced, an algorithm module does not need to be integrated on a processing chip, and the area of the processing chip is reduced.

Description

technical field [0001] The present application relates to the technical field of electrochromism, in particular to a pixel structure unit, a lens module, electronic equipment and a method for eliminating shadows. Background technique [0002] When using the lens module to take pictures, due to the focus shift caused by the increase of the incident light angle, the incident light of the lens module gradually attenuates from the center to the edge, which will cause the imaging of the image sensor used for imaging to appear from the center to the edge. The phenomenon of gradually darkening, this phenomenon is the shadow phenomenon in the imaging of the lens module. [0003] In order to eliminate the shadow phenomenon in the imaging of the lens module, it is usually supplemented with complex image processing algorithms for correction, so as to eliminate the shadow phenomenon in the lens imaging. [0004] However, the use of the above-mentioned algorithm for eliminating shadows ...
