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.1. A method for producing, transmitting and displaying handwritten electronic postcards using an electronic data processing equipment, said postcard having a first and second information page (1, 2), said first information page (1) comprising an electronically registered color image, and the second information page (2) comprises an electronically recorded color image of a substantially rectangular white surface (8) whose surface normal is not necessarily parallel to the surface normal of the color image's image plane, which rectangular surface comprises four pass markers disposed in the corners of the rectangle (4 ) and a centrally located frame (7) which may contain a handwritten message, characterized by detecting the presence of the four pass marks (4) by means of the equipment and measuring the brightness, color and position of the pass marks (4), and the color image of the white surface (8) subsequently using the measured positions of the pass marks (4) optionally transformed in such a way that the pass marks (4) form a rectangle and the light, brightness and color of the transformed color image are then dynamically adjusted for the transformed electronic color image by the measured brightness and then a pruning of the transformed, brightness-regulated color image in such a way that it essentially comprises only the centrally located frame (7) and the final result is stored on the electronic data processing equipment together with the first information page (1) as an electronic postcard. Method according to claim 1, characterized in that the detection of the four pass marks comprises the following steps: producing a gray scale copy of the second information page color image (8), producing and storing a number of copies of the gray scale copy with progressively lower resolution, scanning each of these copies, starting with the lowest resolution copy, to find the positions of the four pass marks (4) in each resolution, using a measure of the correlation of corresponding pixels between the individual copies, comparing the four pass marks (4) positions on the copies having a plurality of predetermined stored pass mark position sets (4 '), each pass mark position set (4') corresponding to a particular perspective angle, and issuing a warning signal if the detected difference between the stored pass mark position sets (4 ') and the copy pass mark position set (4) of the copies is greater than a predetermined threshold. Method according to Claim 1 or 2, characterized in that the transformation of the color image of the white surface (8) comprises dividing the square bounded by the four detected pass marks (4) into at least two triangles and a subsequent piecewise alignment of the color image of the white surface (8) using the found pass mark positions (4) so that the square after the transformation forms essentially a rectangle. Method according to one of Claims 1 to 3, characterized in that the adjustment of light and brightness of the transformed color image comprises measuring the lighting conditions for each of the four pass marks (4) and a subsequent illumination compensation, in that between the pass marks (4). ), a linear stretching and delineation algorithm as well as a bilinear interpolation is performed, and an appropriate color correction is then made on the color image obtained by illumination compensation to attenuate the errors that might be amplified by the illumination compensation. Method according to one or more of claims 1-4, characterized in that the storage of the first and second information pages (1,2) of the electronic postcard is carried out in such a way that the first information page (1) can be freely displayed, while the other information page (2) can only be displayed by specifying a unique password corresponding to the electronic postcard.
