US 2022/0020112 A1 · METHOD FOR TRANSMITTING REDUCED DEPTH INFORMATION AND ELECTRONIC DEVICE

Abstract

The embodiments of the disclosure provide a method for transmitting reduced depth information and an electronic device. The method includes: obtaining a first depth map of an image frame, wherein the first depth map includes a plurality of first depth pixels corresponding to multiple image pixels in the image frame; downscaling the first depth map as a second depth map, wherein the second depth map includes multiple second depth pixels, and each second depth pixel has a depth value; adjusting the second depth map as a third depth map by scaling up the depth value of each second depth pixel based on a specific ratio; dividing the third depth map into multiple fourth depth maps; appending the fourth depth maps to the image frame; encoding the image frame appended with the fourth depth maps; and transmitting the encoded image frame to a client device.
