Abstract
(A1) Die Erfindung behandelt eine Vorrichtung zur optischen Navigation, enthaltend einen Bildsensor, welcher eine Vielzahl von arrayartig angeordneten Bildsensoreinheiten mit jeweils mindestens einer lichtempfindlichen Flaeche aufweist, und mindestens eine Linse, welche zwischen einem abzubildenden Objekt und dem Bildsensor angeordnet ist. Erfindungsgemaess ist ein Mikrolinsenarray vorhanden, wobei mindestens eine Mikrolinse einer Bildsensoreinheit zugeordnet ist.

 

DE 102007042984 A1 UPAB: 20090403 NOVELTY - The device comprises an image sensor array (2) with multiple array-like image sensor units (20). A photo-sensitive surface and a micro lens array (3) are assigned to the image sensor array and are arranged between an imaging object (6) and the image sensor array. Each image sensor unit is assigned a micro lens (30). A substrate layer, particularly made of silicone or polychlorinated biphenyl or plastic is arranged between a carrier and the image sensor array or the radiation source. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an input unit, particularly a computer mouse or a radio control or a console control unit for a data-processing system. USE - Device for optical navigation for controlling a cursor of an image output unit by a relative movement between image sensor and imaging object (Claimed). ADVANTAGE - The photo-sensitive surface and a micro lens array are assigned to the image sensor array and are arranged between an imaging object and the image sensor array, and each image sensor unit is assigned a micro lens, and thus ensures a good resolution and brightness at the edge of the image sensor.
