  • Methods and apparatuses for tone mapping and inverse tone mapping
    Patent number: 11100888
    Abstract: A method of producing at least one output image signal representing, at least, a plurality of output luminance values in an output range of luminance values is disclosed. The method involves: identifying a mapping function based at least in part on a perceptually scaled distribution of a plurality of input luminance values in an input range of luminance values different from the output range of luminance values; transforming the plurality of input luminance values into respective perceptually scaled output luminance values according to the mapping function; transforming the perceptually scaled output luminance values into respective ones of the plurality of output luminance values; and producing the at least one output signal representing, at least, the plurality of output luminance values. Computer-readable media and apparatuses are also disclosed.

  • Cover device and blanket for covering liquid surfaces
    Patent number: 9540833
    Abstract: The present invention relates to a self filling cover device for covering a surface of a liquid, having a shell (2) defining inner cavity, and the inner cavity is to be filled at least partly with liquid, so that the inner cavity is divided in at least two chambers (3,4) by a separating means (5,51,52), and one of the chambers (4) is provided by at least one opening (6) formed in the shell (2).
