Description

PATENTKRAV 1. Fremgangsmåde til fremstilling, fremsendelse og fremvisning af håndskrevne elektroniske postkort ved hjælp af et elektronisk databehandlingsudstyr, hvilket postkort har en første og en anden informationsside (1, 2), hvor den første informationsside (1) omfatter et elektronisk registreret farvebillede, og den anden informationsside (2) omfatter et elektronisk registreret farvebillede af en i det væsentlige rektangulær, hvid flade (8), hvis fladenormal ikke nødvendigvis er parallel med fladenormalen til farvebilledets billedplan, hvilken rektangulær flade omfatter fire i rektanglets hjørner anbragte pas-mærker (4) og en centralt anbragt ramme (7), der kan indeholde en håndskreven meddelelse, kendetegnet ved, at tilstedeværelsen af de fire pasmærker (4) detekteres ved hjælp af udstyret, og at lysstyrke, farve og position for pasmærkeme (4) måles, og at farvebilledet af den hvide flade (8) efterfølgende ved hjælp af de målte positioner for pasmærkeme (4) eventuelt transformeres på en sådan måde, at pasmærkeme (4) danner et rektangel, og at lys, lysstyrke og farve for det transformerede farvebillede derefter justeres dynamisk for det transformerede elektroniske farvebillede ved hjælp af den målte lysstyrke, og at der derefter foretages en beskæring af det transformerede, lysstyrkeregulerede farvebillede på en sådan måde, at dette i det væsentlige kun omfatter den centralt anbragte ramme (7), og at det endelige resultat lagres på det elektroniske databehandlingsudstyr sammen med den første informationsside (1) som et elektronisk postkort. 2. Fremgangsmåde ifølge krav 1,kendetegnet ved, at detekteringen af de fire pasmærker omfatter følgende trin: frembringelse af en gråskalakopi af den anden informationssides farvebillede (8), frembringelse og lagring af et antal kopier af gråskalakopien med progressivt lavere opløsning, gennemsøgning af hver af disse kopier, startende med kopien med den laveste opløsning, med henblik på at finde positionerne for de fire pasmærker (4) i hver enkelt opløsning, idet der anvendes et mål for korrellationen af tilsvarende billedpunkter mellem de enkelte kopier, sammenligning af de fire pasmærkers (4) positioner på kopierne med et antal forudbestemte, lagrede pasmærkepositionssæt (4'), hvor hvert pasmærkepositionssæt (4') svarer til en bestemt perspektiwinkel, og afgivelse af et advarselssignal, hvis den detekterede forskel mellem de lagrede pasmærkepositionssæt (4') og kopiernes pasmærkepositionssæt (4) er større end en forudbestemt tærskelværdi. 3. Fremgangsmåde ifølge krav 1 eller 2, kendetegnet ved, at transformeringen af farvebilledet af den hvide flade (8) omfatter opdeling af den af de fire detekterede pasmærker (4) afgrænsede firkant i mindst to trekanter og en efterfølgende stykkevis afftn transformation af farvebilledet af den hvide flade (8) ved hjælp af de fundne pas-mærkepositioner (4), således at firkanten efter transformationen i det væsentlige danner et rektangel. 4. Fremgangsmåde ifølge et af kravene 1-3,kendetegnet ved, at justeringen af lys og lysstyrke for det transformerede farvebillede omfatter måling af belysningsforholdene for hvert af de fire pasmærker (4) og en efterfølgende belysningskompensering, idet der på de mellem pasmærkeme (4) beliggende billedpunkter udføres en lineær stræk- og afgrænsningsalgoritme samt en bilineær interpolation, og at der derefter på det ved belysningskompenseringen opnåede farvebillede foretages en passende farvekorrek-tion til dæmpning af de fejl, der måtte være forstærket ved belysningskompenseringen. 5. Fremgangsmåde ifølge et eller flere af kravene 1-4, kendetegnet ved, at lagringen af det elektroniske postkorts første og anden informationsside (1,2) udføres på en sådan måde, at den første informationsside (1) frit kan fremvises, medens den anden informationsside (2) kun kan fremvises ved angivelse af en til det elektroniske postkort svarende unik adgangskode.
