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

The embodiment of the invention provides a data processing method, equipment and a storage medium. To-be-processed image data is obtained from an original image, basic layer image data is coded basedon a first preset coding rule, and enhancement layer image data is coded based on a second preset coding rule. Therefore, the precision of the to-be-processed image data is reserved as much as possible, the dynamic range and the later editing space of the to-be-processed image data are guaranteed, a final target image code stream is generated according to the base layer image code stream and the enhancement layer image code stream, and the purpose of compatibility is achieved.

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...
