Title:
MICROLENS ARRAY IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/179462
Kind Code:
A1
Abstract:
The present invention relates to a microlens array imaging system, comprising: a microlens array comprising a plurality of microlenses arranged to be adjacent to each other; an opaque light-shielding fabricated structure provided between each pair of adjacent microlenses and forming a grid structure having a planar or curved surface with the plurality of microlenses; a photosensitive pixel array comprising a plurality of photosensitive elements disposed below the microlenses, respectively; and an imaging result processor receiving an electrical signal output by the photosensitive pixel array and converting the electrical signal into image information, so as to perform decoding and processing on the image information. The invention overcomes low-resolution issues of individual microlenses, and improves the overall resolution of a camera having a light field-capturing function, thereby ensuring independent imaging of each microlens, preventing interference between imaging results, and ensuring data accuracy.
