Title (EN) METHOD OF DISPLAYING A SEQUENCE OF IMAGES FROM A DIGITAL VIDEOCAMERA
(FR) PROCEDE D'AFFICHAGE D'UNE SEQUENCE D'IMAGES A PARTIR D'UNE CAMERA VIDEO NUMERIQUE
Abstract: front page image
(EN)Method for rapid FM-halftoning of pictures where all possible values in the picture correspond to a halftone plate, in which the halftone dots are maximally scattered. If the picture that is to be halftoned contains 256 different tone values, thus 256 halftone plates are pre-calculated, all constituted only by ones and zeros, that together build a halftoning volume. At the halftoning itself no comparison is then executed, but the choice to set a certain position in the picture or not is instead solved by a table-look-up method. The value of the input picture gives index in the table (that is which halftone plate that is to be used) and then the value from the corresponding position in the halftone plate is copied into the output picture.
(FR)Procédé de simili rapide en FM d'images où toutes les valeurs possibles de l'image correspondent à une planche simili où les points de simili sont dispersés au maximum. Si l'image à traiter contient 256 valeurs de teinte différentes, on prédétermine 256 planches de simili, toutes en un et zéro uniquement, qui constituent ensemble un volume de simili. Au niveau du simili proprement dit, aucune comparaison n'intervient mais le choix ou le non-choix d'une position dans l'image repose sur la consultation d'un tableau. La valeur de l'image à l'entrée renvoie à une indexation dans le tableau (planche simili destinée à être utilisée) et la valeur de la position correspondante dans la planche simili est copiée dans l'image à la sortie de l'opération.
