Title: Lampe a decharge
Inventor: DEVONSHIRE ROBIN
IPC: H01J61/82
Filed: 1998-07-14
Abstract: On sait qu'on peut modifier la sortie spectrale de certaines lampes à décharge par application d'ondes pulsées plutôt que d'ondes sinusoïdales simples. On a utilisé cet effet dans le passé afin de fabriquer des lampes fluorescentes à sorties de couleurs variables. L'invention consiste à appliquer des impulsions courtes (environ 1µS) à une fréquence d'environ 5 kHz à une lampe à décharge, telle qu'une lampe au mercure/argon basse pression, de manière à déplacer le rapport des intensités de deux des lignes de mercure, en particulier, les lignes de 254 nm et 365 nm, parmi lesquelles la ligne de 254 nm est prédominante pour une application d'ondes sinusoïdales, vers la longueur d'onde la plus élevée. Ceci permet d'augmenter considérablement l'efficacité de la lampe au moyen de luminophores excités par ces émissions d'ultraviolets, à cause de la limitation du déplacement de Stokes.

Title: Detection of transitions in video sequences
Inventor: GOLIN STUART JAY
IPC: H04N7/30
Filed: 1998-12-22
Abstract: Frame dissimilarity measure (FDM) values are generated (102) for pairs of frames in a video sequence that are separated by a specified timing window size, where each FDM value is the ratio of a net dissimilarity measure and a cumulative dissimilarity measure. In one embodiment, a first threshold condition (110) is applied to identify peaks in the FDM data that could correspond to transitions between shots in a video sequence. A second threshold condition (116) is applied to the FDM data adjacent to the detected peaks to identify frames at the start and end of the transition. The first threshold condition determines whether the FDM values exceed a first specified threshold level, while the second threshold condition determines whether the FDM values fall below a second specified threshold level. The net and cumulative dissimilarity measures may be based on histograms for the two frames. The present invention is effective in detecting gradual transitions between shots, such as wipes, dissolves and fades, as well as abrupt transitions, such as cuts.
