Abstract: A method is described for inverse tone mapping the luminance (Yt(p)) of each pixel (p) of at least one image (It) of this sequence into an expanded luminance Ytexp(p)=Yt(p)Et(p). Ytenh(p), wherein Et(p) is an expansion exponent value extracted from an expansion exponent map built from low pass motion-compensated temporal filtering of said image (It) and wherein Ytenh(p) is a luminance-enhancement value extracted from a luminance-enhancement map built from high pass motion-compensated temporal filtering of said image (It).

Abstract: A device and a method for temporal metering of events and to a device and a method for temporal analysis of events. The temporal metering device when operating obtains current times for each occurrence of physical events, and records in at least one metering file, information authorizing a temporal reconstitution of the occurrences. This device comprises a module for summary processing of the occurrences and of the current times, producing condensed results which are recorded in predefined data structures of prefixed sizes of the metering file, so as to make it possible to keep the size of this file constant during successive recordings of this information. Applications to checks of software services and to analyses of computing malfunctions.
