Assignee: ARASHI VISION INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 12:
13. A portable terminal, comprising:
one or more processors;
a memory; and
one or more computer programs, wherein the one or more computer programs are stored in the memory and configured to be executed by the one or more processors, the processors being programmed to execute the computer programs to perform operations including:
acquire a plurality of aligned images;
calculate gradient information of each image respectively;
set a mask image of each image and generate a target gradient image;
perform a gradient operation on the target gradient image to obtain a target Laplacian image;
perform a deconvolution transform on the Laplacian image to generate a fused panoramic image;
wherein,
the plurality of aligned images are capable of being stitched into one panoramic image, and a number of the aligned images is equal to n, with n≥2;
the aligned images represent that any pixel in the n aligned images corresponds to a pixel in the panoramic image obtained by stitching;

wherein the calculate the gradient information of each image respectively comprises:
down-sample each image sequentially to obtain a corresponding down-sampled image;
calculate horizontal forward gradient information, vertical forward gradient information, horizontal backward gradient information and vertical backward gradient information of each down-sampled image respectively.
