  • Patent number: 10645359
    Abstract: A method for processing a digital image including image elements having a first luminance component. The first luminance component has a first value in a first predetermined interval. The display can render second values of second luminance components included in a second predetermined interval. The method includes: determining information representative of image brightness perceived by an observer, based on the first values of the first luminance component; calculating an expansion exponent as a function of the determined brightness information; transforming the first luminance components into the second luminance components, including calculating an intermediate luminance value by applying the calculated expansion exponent to the first luminance component value, multiplying the intermediate value by a length of the second interval, and obtaining the second value of the second luminance component based on the multiplied intermediate luminance value.

  • Publication number: 20200007839
    Abstract: A method for processing at least one digital image for reproduction on a display device. The image includes image elements, an image element being associated with color information having, in a first color space, a luminance component and chrominance components. The method includes the following acts: determining a number of image elements, known as “bright” elements, at least the luminance component of which has a value greater than a first predetermined threshold; evaluating a maximum tolerated brightness value as a decreasing function of the number of counted image elements; and transforming the first luminance components of the image elements to second luminance components, including for an image element, calculating an intermediate luminance value by applying an expansion exponent to the first luminance component value and multiplying the intermediate value calculated by the evaluated maximum tolerated luminosity value.

  • Patent number: 10326971
    Abstract: A method for processing a digital image for rendering on a display. The image includes image elements associated with color information represented in a colorimetric space having a luminance and chrominance components. The luminance component has a value in a first predetermined interval. The display can render values of luminance components included in a second predetermined interval, of greater length than the first interval. The method includes: determining information representative of image brightness perceived by an observer, based on the values of the first luminance component; calculating an expansion exponent as a function of the determined brightness information; transforming the first luminance components into second luminance components, including calculating an intermediate luminance value by applying the calculated expansion exponent to the first luminance component value and multiplying the intermediate value by the length of the second interval.
