IMAGE ENCODING METHOD AND IMAGE ENCODING APPARATUS

摘要

An image encoding method for an encoding system includes receiving a first image captured by a main camera and a second image captured by a sub camera provided in the same plane; comparing pixel values of pixels at first coordinates of each of the first and second images to obtain a first difference value; determining the first coordinates are in surface or back region in case of the first difference value is not more than or more than a first threshold value; pixel-shifting the second image by a first shift amount; and comparing the pixel value at the first coordinates of the first image with that of the second image after the pixel shift to obtain a second difference value, determining whether the first coordinates are in the surface or back region based on the second difference value, and recording into a second frame different from the first frame.

1. An image encoding method for an encoding system comprising:
receiving a first image captured by a main camera and a second image captured simultaneously with the first image by a sub camera provided in the same plane with the main camera; comparing pixel values of pixels at first coordinates of each of the first image and the second image to obtain a first difference value; determining that the first coordinates are in a surface region in case of the first difference value is not more than a first threshold value, and that the coordinates are in a back region in case of the first difference value is more than the first threshold value, and recording into a first frame; pixel-shifting the second image by a first shift amount in a direction based on a positional relationship between the main camera and the sub camera; and comparing the pixel value of the pixel at the first coordinates of the first image with a pixel value of a pixel at the first coordinates of the second image after the pixel shift to obtain a second difference value, determining whether the first coordinates are in the surface region or the back region on a basis of the second difference value, and recording into a second frame different from the first frame.
