Abstract: Embodiments of the invention relate to a method for producing a color sensor with a sensor characteristic adjusted by three sensor elements that each comprise an element characteristic, and a color filter cooperating with the sensor elements and consisting of color filter elements that each comprise a filter element characteristic, and to a color sensor. Embodiments include a method with which a color sensor with a precisely adjustable sensor characteristic can be produced from several photosensitive elements and from simple filter elements is solved in that the particular filter element characteristics are adjusted in such a manner that they have in cooperation with the respective element characteristic an interim characteristic of the sensor which deviates from the sensor characteristic on the whole, wherein the sensor characteristic is generated from the interim characteristic by a transformation algorithm using transformation parameters.

Abstract: Embodiments relate to a proximity sensor, particularly for mobile devices like smartphones, tablets or the like. The proximity detector includes a first emitter-detector pair with a first light emitter and a first photodetector, wherein the first light emitter and the first photodetector are separated by a first distance, and a second emitter-detector pair with a second light emitter and a second photodetector, wherein the second light emitter and the second photodetector are separated by a second distance, wherein the first distance is different from the second distance. Embodiments further relate to a method for detecting the proximity of a target to a proximity sensor.

Abstract: The invention relates to a UV light sensor produced in a CMOS method, comprising a substrate that has a surface, one or more sensor elements that detect radiation and are designed in said substrate, at least one passivation layer arranged over said substrate surface, and a functional layer that is arranged over said passivation layer and designed in the form of at least one filter. The problem addressed by the invention of providing a UV light sensor which is sensitive exclusively within the UV wavelength range is solved, in terms of arrangement, by means of filters designed directly on a planar passivation layer, and stray light suppressing means around said at least one sensor element and/or around the UV light sensor. In terms of the method, the problem is solved by measuring two output signal from at least two photo diodes fitted with different filters, and by determining a mathematical relationship between the two output signals.
