  • the computer processor 21 of each capture station 20 uses data compression software (e.g. PKZIP.EXE, a public domain file compression utility program) to compress each file before it is transmitted to the central unit 10. This step can result in a 4-to-l to 20-to-l reduction in file size.

  • the capture unit 20 is geographically remote from the central unit 10.

  • the image files can be compressed by the capture stations 20 before transmission to the central unit 10. It may also be desirable to similarly compress the files containing the audio segment and other information associated with each gemstone. To the extent such data has been compressed either by the capture unit 20 or the central unit 10, the display unit must reverse this process (i.e., uncompress) the files received from the central unit before the data can be used by the display unit.

Abstract

Système commercial informatisé permettant de réaliser la mémorisation centralisée d'images de pierres précieuses, ainsi que leur saisie à distance, leur accès et leur affichage. Un ordinateur central (10) conserve une base de données des images d'un inventaire de pierres précieuses, ainsi que les informations les concernant, tels que leur poids, leur couleur, leur clarté et leur prix individuel. Un ou plusieurs ensembles de saisie à distance (20) situés par exemple au niveau des installations de taille et de polissage des pierres ou chez un grossiste, possède chacun une caméra (22) servant à saisir les images des pierres, ainsi qu'un clavier (23) ou d'autres moyens servant à entrer les informations concernant chaque pierre. Ces données sont transmises à l'ordinateur central (10) au moyen d'un réseau de télécommunication ou par l'intermédiaire de moyens optiques ou magnétiques amovibles (33). On peut avoir accès auxdites images, ainsi qu'aux données correspondantes mémorisées par l'ordinateur central (10) et les afficher par l'intermédiaire d'un réseau de télécommunications au moyen de plusieurs ensembles d'affichage à distance (30). Dans le mode de réalisation préféré de l'invention, les acheteurs peuvent également utiliser chaque ensemble d'affichage (30), afin de passer des commandes de pierres précieuses auprès de l'ordinateur central (10).
