Problems solved by technology

Currently, the most widely used mainstream image compression format on the Internet, such as JPEG (Joint Photographic Experts Group, is an international standard for lossy compression for still images proposed by the Joint Photographic Experts Group), due to the limitation of data bit depth, it can only retain Part of the dynamic range of the scene captured by the camera
[0003] In recent years, in order to adapt to high dynamic range (High Dynamic Range, HDR) images, some image compression technologies supporting high bit depth have been proposed, but they are not compatible with some mainstream image formats

Abstract

Embodiments of the present application provide a data processing method, device, and storage medium. The image data to be processed is obtained from the original image, the base layer image data is encoded based on the first preset encoding rule, and the base layer image data is encoded based on the second preset encoding rule. Enhancement layer image data is encoded, so as to preserve the accuracy of the image data to be processed as much as possible, to ensure the dynamic range and post-editing space of the image data to be processed, and then generate the final The target image code stream to achieve the purpose of compatibility.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a data processing method, device and storage medium. Background technique [0002] With the gradual increase in the performance of image sensor hardware, the dynamic range of the actual scene that the camera can capture is also increasing. Currently, the most widely used mainstream image compression format on the Internet, such as JPEG (Joint Photographic Experts Group, is an international standard for lossy compression for still images proposed by the Joint Photographic Experts Group), due to the limitation of data bit depth, it can only retain The portion of the dynamic range of the scene captured by the camera. [0003] In recent years, in order to adapt to high dynamic range (High Dynamic Range, HDR) images, some image compression technologies supporting high bit depths have been continuously proposed, but they are not compatible with some mainstream image formats. C...
