Problems solved by technology

However, because HDR cameras are expensive, users may only have Standard Dynamic Range (SDR) cameras
Therefore, when images from SDR cameras are stitched together to create a 360° image or video, some details in the image or video may be lost

Abstract

An electronic device includes a receiver receiving a compressed bitstream and metadata. The electronic device also includes at least one processor that generates an HDR image by decoding the compressed bitstream, identifies viewpoint information based on an orientation of the electronic device, maps the HDR image onto a surface, and renders a portion of the HDR image based on the metadata and theviewpoint information. A display displays the portion of the HDR image.

Description

technical field [0001] The present disclosure relates generally to image enhancement. More specifically, the present disclosure relates to methods and apparatus for creating, streaming and rendering high dynamic range (HDR) images. Background technique [0002] Currently, new high dynamic range (HDR) cameras and displays are gaining prominence. HDR cameras can take images with an intensity that can vary from 0.01 to about 10000 nits. Due to the high cost of HDR cameras, HDR content is mainly created by studios, and ordinary consumers cannot afford HDR cameras yet. [0003] 360° video typically includes a high dynamic range covering very dark areas to very bright objects. However, because HDR cameras are expensive, users may only have Standard Dynamic Range (SDR) cameras. Therefore, when images from SDR cameras are stitched together to create a 360° image or video, some details in the image or video may be lost. Contents of the invention [0004] The present disclosure...
