Abstract: This invention relates to a device for counting products (1) that are thin, stacked side by side and arranged edgewise in trays (2) packaged under a translucent shrink-on film, characterized in that it comprises:means (7) for illuminating the tray;means (91) for detecting the positioning of a tray on a mobile shuttle (81, 21) driven with a displacement movement;means (4, 5, 6) for performing multiple scannings of the tray by a linear reading beam of a linear camera during the displacement in a direction that is perpendicular to the linear beam;means for storing the light data contained in the linear beam, andcounting means for each scanning of the number of products.

Abstract: The present invention relates to a device for the data processing of linear images of generatrices of an article having an axis of revolution.The images being detected by a linear image detector having photosensitive points, the device has a memory (24) and a calculator (23) adapted to calculate, for each point of the linear image detector, data values of images coming from such point during a first processing period which corresponds to a complete revolution of the article and to store said average value in the memory (24).The device also has a memory (21) adapted to store all the image data coming from the linear image detector during the course of a complete revolution of the article and restore them during a second processing period after the first processing period.Finally, it comprises a threshold memory (26) which, for each point of the photosensitive detector, stores at least the threshold information.The invention applies to the inspection of bodies of revolution.
