Title:
METHOD AND PHOTOGRAPHING DEVICE FOR ACQUIRING DEPTH INFORMATION
Document Type and Number:
WIPO Patent Application WO/2017/181381
Kind Code:
A1
Abstract:
A method and photographing device for acquiring depth information. The photographing device comprises a camera lens and an image sensor, and the image sensor comprises at least one microlens. Each of the at least one microlens corresponds to one pixel, and one pixel comprises N sub-pixels, N being an integer greater than or equal to four. The method comprises: regarding each of the at least one microlens on the image sensor, the photographing device receives, via a pixel corresponding to said microlens on the image sensor, an optical signal; the photographing device determines, according to the optical signal received by the pixel corresponding to said microlens and a position relationship among the N sub-pixels of said pixel, phase information of said optical signal received by said pixel; the photographing device acquires, according to a predetermined correspondence relationship between phase information and depth information, depth information corresponding to the phase information; and the photographing device determines, according to the depth information corresponding to each of the at least one microlens, depth information corresponding to a photographed object.
