Patent FR-2662039-A1 (FR)
Title: Dispositif pour indiquer la polarite d'un signal video.
Inventor: MICHEL ERNOU
IPC: H04N7/171
Filed: 1990-05-11
Abstract: Le dispositif est muni d'un compteur (21) pour compter, pendant un signal de suppression de trame, les signaux de synchronisation de ligne appliqués à son entrée d'horloge (CP). L'entrée (CEP) d'autorisation de comptage du compteur reçoit un signal dont la durée correspond à la durée de cinq demi-lignes. Le compteur repart à zéro lorsqu'il a compté cinq signaux, en indiquant alors sur une sortie spécifique (TC) que le comptage a atteint cinq, et cette sortie (TC) est reliée à un circuit logique (14 à 18), qui fournit à chaque fin d'intervalle de suppression de trame un signal binaire (19) qui reste inchangé lorsque le chiffre de comptage du compteur a atteint cinq et qui est inversé dans le cas contraire. Ce signal binaire commande un démodulateur pour l'adapter à la polarité. Application: Récepteurs de télévision, soit multistandards, soit dans lesquels il est nécessaire de reconnaître la polarité d'un signal video qui est inversé par rapport au signal normal d'une norme d'émission donnée, par exemple dans le but de renforcer un brouillage.

Title: Method of deriving a matrix image with filtering of mean values of lines of pixels
Inventor: MARC ARQUES
IPC: H04N5/365
Filed: 1992-01-17
Abstract: The invention relates to a method of producing an electronic image from a matrix-type photosensitive sensor 10. The line correlated noise, originating from instabilities in supply voltages on the line conductors, produces visible defects to which the eye is particularly sensitive. According to the invention, the variations in mean illumination (Sim) of each line are evaluated when passing from one line to the other, and the variations which are too abrupt are filtered by considering that they cannot come from the image (the latter being assumed not to contain abrupt line transition patterns), but only from line correlated noise. The difference between the mean illumination Sim of one line i and the mean illumination Simf of this line after suppression of the too-rapid variations serves as a correction signal Ci for all the pixels of this line i. The filtering is done either directly on the time-based variations of the mean line illumination or on a Fourier transform in the space of the spatial frequencies of the image.
