More Information
Summary:This application provides a tone mapping method and apparatus for a panoramic image. The tone mapping method includes: determining one or more target metadata information units of a first pixel from a plurality of metadata information units, where the plurality of metadata information units are obtained by parsing a bitstream, the first pixel is any pixel in a to-be-processed panoramic video two-dimensional planar projection, the plurality of metadata information units correspond to a plurality of segmented regions included in a panoramic video three-dimensional spherical representation panoramic image, and there is a mapping relationship between the panoramic video two-dimensional planar projection and the panoramic video three-dimensional spherical representation panoramic image; and performing tone mapping on a pixel value of the first pixel based on the one or more target metadata information units, to obtain a target tone mapping value of the first pixel.
