Abstract: A method for encoding a sequence of high dynamic range pictures is disclosed. The method comprises for each picture of the sequence: obtaining a value representative of an average luminance of the high dynamic range picture; processing the high dynamic range picture so that the value representative of an average luminance of the processed picture is closer to a defined average luminance value than is the value representative of an average luminance of the high dynamic range picture; decomposing the processed high dynamic range picture in at least one first low dynamic range picture and one second low dynamic range picture of lower resolution representative of a global illumination of the scene; and encoding the first and second low dynamic range pictures and a data function of said value representative of an average luminance of said high dynamic range picture.

Abstract: The invention relates to cosmetic methods for improving the microparasol organization in keratinocytes, protecting skin against ultraviolet radiation, decreasing DNA photodamage in keratinocytes and melanocytes, attenuating age-related pigmentation defects and the effects of photoaging on the skin. The methods include applying a composition comprising a peptide compound of general formula (I), R1-(AA)n-X1—X2—X3-Asp-Leu-Lys-Lys-X4—X5-(AA)p-R2, and a cosmetically acceptable medium.

Abstract: The present invention relates to the domain of video equipment. It relates to a phase-locked loop able to recover the timing of a synchronization signal comprising a temporal discontinuity of amaximum amplitude equal to PCR_Modulus, the loop comprising: a sample comparator comparing the samples and the local samples of a synthesized signal, means for producing the synthesized signal from a corrected signal, a corrector receiving a comparison result delivered by the comparison means and delivering the corrected signal, According to the invention, the comparison means comprises the means to determine a difference in value between the local samples and the samples of the synchronization signal and in that the comparison result has a value that depends on the value ? and on the difference between the value ? and the value PCR_Modulus/2.
