A method of correcting red-eye features in a digital image includes generating a list of possible features by scanning through each pixel in the image searching for saturation and/or lightness profiles characteristic of red-eye features. For each feature in the list, an attempt is made to find an isolated area of correctable pixels which could correspond to a red-eye feature. Each successful attempt is recorded in a list of areas. Each area is then analysed to calculate statistics and record properties of that area, and validated using the calculated statistics and properties to determine whether or not that area is caused by red-eye. Areas not caused by red-eye and overlapping areas are removed from the list. Each area remaining is corrected to reduce the effect of red-eye. More than one type of feature may be identified in the initial search for features.

L'invention a trait à un procédé de correction d'éléments yeux rouges dans une image numérique, consistant à générer une liste d'éléments possibles en balayant chaque pixel de l'image pour trouver des profils de saturation et/ou de clarté caractéristiques d'éléments yeux rouges. Pour chaque élément de la liste, on tente de trouver une zone isolée de pixels corrigibles pouvant correspondre à un élément yeux rouges. Chaque tentative fructueuse est enregistrée dans une liste de zones. Chaque zone est ensuite analysée, afin que des statistiques de ladite zone soient calculées et que des propriétés en soient enregistrées, et validée au moyen des statistiques et des propriétés calculées, pour que l'on puisse déterminer si ladite zone est due ou non à un élément yeux rouges. Les zones qui ne sont pas dues à un élément yeux rouges et celles qui se chevauchent sont éliminées de la liste. Chaque zone restante est corrigée, afin que soit réduit l'effet yeux rouges. Lors de la recherche initiale d'éléments, plusieurs types d'éléments peuvent être identifiés.
