CA 2492288

A method of system is provided for assaying specimens. In connection with such system or method, plural multi-pixel target images of a field of view are obtained at different corresponding points in time over a given sample period. A background image is obtained using a plural set of the plural target images. For a range of points in time, the background image is removed from the target images to produce corresponding background-removed target images. Analysis is performed using at least a portion of the corresponding background-removed target images to identify visible features of the specimens. A holding structure is provided to hold a set of discrete specimen containers. A positioning mechanism is provided to position a plural subset of the containers to place the moving specimens within the plural subset of the containers within a field of view of the camera.

L'invention concerne un procédé et un système servant à analyser des spécimens. Ce procédé et ce système consistent à obtenir plusieurs images ciblées contenant des pixels multiples d'un champ de vision à différents points temporels correspondant sur une période d'échantillonnage donnée. Une image d'arrière-plan est obtenue au moyen de plusieurs ensembles de ces images ciblées. Pendant une série de points temporels, l'image d'arrière-plan est retirée des images ciblées afin de produire des images ciblées correspondantes exemptes d'arrière-plan. L'analyse est exécutée au moyen d'au moins une partie des images ciblées correspondantes exemptes d'arrière-plan afin d'identifier des caractéristiques visibles des spécimens. Une structure de support sert à contenir un ensemble de réservoirs discrets pour les spécimens. Un mécanisme de positionnement sert à placer plusieurs sous-ensembles de ces réservoirs, de manière à placer les spécimens en mouvement à l'intérieur de ces réservoirs et du champ de vision de la caméra.
