    摘要： A method for translating metadata related to enhancement of a video signal according to a first high dynamic range video distribution type into metadata related to enhancement of a video signal according to a second high dynamic range video distribution type. Translation is done using a lookup table being determined according to differences between a test image reconstructed using the metadata of first type and the same image reconstructed using the metadata of second type. A receiver apparatus and a transmitter apparatus comprising the translation method are also disclosed.

    摘要： The invention related to a method for color processing in view of displaying a video image on a display device. It comprises:
    - retrieving (S1) a spectral power distribution associated with at least one group of light elements of the display device, said group of light elements displaying a color component of the video image to be displayed,
    - computing (S2), in a range of said spectral power distribution, called range of noxiousness, a noxiousness value representative of the noxiousness of the light emitted by the group of light elements of the display device,
    - comparing (S3) said noxiousness value to a bound value of noxiousness, and
    - if said noxiousness value is greater than said bound value, modifying (S4) the content of the image or modifying display control parameters of the display device such that said noxiousness value becomes less than said bound value.
