(EN) Method of producing electronic postcards
Abrégé
(EN)
A method of producing, mailing and displaying electronic postcards having a first and a second information page (1, 2) is provided, said second information page (2) provided with a frame (7). By means of four register marks (4) arranged on a white surface a photographed image (8) of the white surface may be corrected for perspective distortion and trimmed by detection of the presence of the four register marks (4). The contrasts and positions of the register marks (4) are measured, and the colour image of the white surface (8) is subsequently transformed such that the register marks (4) form a rectangle. The brightness and contrast of the transformed colour image are then adjusted dynamically and a subsequent trimming of the transformed and contrast-adjusted colour image is carried out in such a manner that the image substantially only comprises the frame (7). The final result is stored together with the first information page (1) as an electronic postcard on the data processing equipment. The storage of the first and second information page (1, 2) of the electronic postcard is effected such that the first information page (1) is publicly displayed, while the second information page (2) only is displayed after an access code to the electronic postcard has been entered. As a result a method of producing electronic postcards is obtained, which may be exploited by more simple means than hitherto.
