Title (EN) DEVICE OF PROCESSING DEAD PIXEL
(FR) DISPOSITIF DE TRAITEMENT DE PIXEL MORT
Abstract: front page image
(EN) A dead pixel processing device is disclosed. The dead pixel processing device separates an inputted Bayer pattern image into corresponding component data; calculates the distribution (pattern) of pixels based on the median of each data; calculates a comparing value based on a component having a center pixel; outputs an external flag which informs whether there are a dead pixel and/or a hot pixel by using the comparing value; compares the values of the center pixel and adjacent pixels in the component having the center pixel; calculates a measuring value based on the center pixel; outputs an internal flag by using the measuring value; and corrects the dead pixel or the hot pixel. With the present invention, an image can be corrected by detecting a corresponding dead pixel and hot pixel.
(FR) Dispositif de traitement de pixel mort, lequel sépare une image à configuration Bayer à l'entrée en données de composantes correspondantes ; calcule la distribution (configuration) des pixels sur la base de la valeur médiane de chacune des données; calcule une valeur de comparaison d'après une composante ayant un pixel central ; fournit en sortie un drapeau externe précisant s'il existe un pixel mort et/ou un pixel chaud sur la base de la valeur de comparaison ; compare les valeurs du pixel central et des pixels adjacents dans la composante ayant le pixel central; calcule une valeur de mesure sur la base du pixel central ; fournit en sortie un drapeau interne sur la base de la valeur de mesure ; et corrige le pixel mort ou le pixel chaud. On peut ainsi corriger une image par détection de pixel mort et de pixel chaud correspondant.
