Title:
ENCODING/DECODING METHOD, ELECTRONIC DEVICE, COMMUNICATION SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/143205
Kind Code:
A1
Abstract:
Embodiments of the present application provide an encoding/decoding method, an electronic device, a communication system, and a storage medium. The encoding method comprises: after a photographing instruction sent by a second device is received, starting a first camera and a second camera; encoding a first panoramic image to obtain a first compressed image, the first panoramic image being any image in a first panoramic image stream; obtaining a first difference image according to the first panoramic image and a first close-up image, the first close-up image being an image, synchronously collected together with the first panoramic image, in a first close-up image stream; encoding the first difference image to obtain a second compressed image; and sending the first compressed image and the second compressed image to the second device. Because the picture of the close-up image is a close-up of a local area on the panoramic image, the data volume of the difference image is small, and the problem of picture jitter caused by I-frame concurrency is avoided.
