Description
Die Erfindung betrifft ein Blendensystem für eine Kamera, die einen Bildsensor und wenigstens eine Lichtquelle aufweist, sowie eine Kamera mit einem entsprechenden Blendensystem.The invention relates to an aperture system for a camera that has an image sensor and at least one light source, as well as a camera with a corresponding aperture system.
Aus den Patentschriften
Aufgabe der Erfindung ist es, ein Übersprechen von Lichtquellen einer Kamera auf einen Bildsensor gegenüber dem Stand der Technik weiter zu reduzieren.The object of the invention is to further reduce crosstalk from light sources of a camera to an image sensor compared to the prior art.
Die Aufgabe wird durch das erfindungsgemäße Blendensystem und die erfindungsgemäße Kamera gelöst.The task is solved by the aperture system according to the invention and the camera according to the invention.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.
Vorteilhaft ist einem Blendensystem für eine Kamera, die einen Bildsensor und wenigstens eine Lichtquelle aufweist, vorgesehen, mit einem zentralen Blendenring und wenigstens einem äußeren Blendenring, wobei der zentrale Blendenring und der äußere Blendenring über einen gebogenen, elastischen Steg miteinander verbunden sind.An aperture system for a camera which has an image sensor and at least one light source is advantageously provided, with a central aperture ring and at least one outer aperture ring, the central aperture ring and the outer aperture ring being connected to one another via a curved, elastic web.
Das erfindungsgemäße Blendensystem hat den Vorteil, dass die verschiedenen Blenden bzw. Abschattungsflächen in einem Bauteil einstückig bereitgestellt werden können. Die gebogenen elastischen Stege haben den Vorteil, dass die Blenden für die Lichtquellen in Relation zu der Blende für den Bildsensor in ihrer Ausrichtung und Position beweglich bleiben. Dadurch wird es möglich, dass im Herstellungsverfahren der Kamera Fertigungstoleranzen leicht ausgeglichen werden können.The aperture system according to the invention has the advantage that the various apertures or shading surfaces can be provided in one piece in one component. The curved elastic webs have the advantage that the apertures for the light sources remain movable in their orientation and position in relation to the aperture for the image sensor. This makes it possible for manufacturing tolerances in the camera manufacturing process to be easily compensated for.
Vorteilhaft weist der Steg des Blendensystems eine geringere Höhe auf als die beiden Blendenringe. Durch die geringere Ausdehnung erhalten die Stege eine höhere Elastizität.The web of the aperture system advantageously has a lower height than the two aperture rings. The smaller expansion gives the webs greater elasticity.
Vorteilhaft wird das Blendensystem in einem Kunststoff-Spritzgussverfahren hergestellt.The panel system is advantageously manufactured using a plastic injection molding process.
Weiterhin ist es von Vorteil, wenn wenigstens ein Blendenring Befestigung oder Ausnehmungen aufweist, die beispielsweise mit Ausnehmungen der Kamera oder einer Leiterplatte der Kamera korrespondieren.Furthermore, it is advantageous if at least one aperture ring has fastenings or recesses that correspond, for example, to recesses in the camera or a circuit board of the camera.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnungen näher erläutert.The invention is explained in more detail below using exemplary embodiments with reference to the drawings.
