![]() ![]() The method of claim 1, wherein in the ambient-light adjustment function, for one or more input luminance values, the corresponding output values are lower than the input values when ambient light intensity in the target viewing environment is lower than ambient light intensity in the reference viewing environment.Ħ. The method of claim 1, wherein in the ambient-light adjustment function, for one or more input luminance values, the corresponding output values are higher than the input values when ambient light intensity in the target viewing environment is higher than ambient light intensity in the reference viewing environment.ĥ. The method of claim 1, wherein the ambient-light adjustment function is the identity function when ambient light intensity in the target viewing environment is approximately the same as in the reference viewing environment.Ĥ. A method for ambient-light-adaptive display management with a processor, the method comprising: receiving an input image, metadata related to the input image, and an ambient-light signal, wherein the metadata comprises at least one of a minimum luminance value, a midpoint luminance value and a maximum luminance value of the input image obtaining an ambient-light adjustment function which maps input luminance values in a reference viewing environment to output luminance values in a target viewing environment, wherein the target viewing environment is determined based on the ambient-light signal applying the ambient-light adjustment function to said at least one of the minimum, midpoint and maximum luminance value, to generate new metadata obtaining a first tone-mapping function based on the new metadata and parameters for a target display obtaining a second tone-mapping function based on the ambient-light adjustment function and the first tone-mapping function and applying the second tone-mapping function to the input image to generate an output image for the target display.ģ. A method for ambient-light-adaptive display management with a processor, the method comprising: receiving an input image, metadata related to the input image, and an ambient-light signal, wherein the metadata comprises at least one of a minimum luminance value, a midpoint luminance value and a maximum luminance value of the input image obtaining an ambient-light adjustment function which maps input luminance values in a reference viewing environment to output luminance values in a target viewing environment, wherein the target viewing environment is determined based on the ambient-light signal applying the ambient-light adjustment function to the input image to generate a virtual image, and to said at least one of the minimum, midpoint and maximum luminance values to generate new metadata for the virtual image obtaining a tone-mapping function based on the new metadata and parameters for a target display and applying the tone-mapping function to the virtual image to generate an output image for the target display.Ģ. ![]()
