摘要： An ambient light detector, a detector array and a method are disclosed. An ambient light sensor includes a first plurality of sensor elements, where each sensor element is configured to provide a signal in response to a level of illumination and a second plurality of reference elements, each reference element configured to provide a reference signal and each including a blocking element configured to shield the respective reference element from being illuminated, where the first plurality is larger than the second plurality and the first plurality of sensor elements and the second plurality of reference elements are arranged in an array, and where a sensor element and a reference element are laterally arranged on or in a common layer substrate sharing at least one common first contact.

摘要： A device for cancelling undesired fractions in a detected signal may include a first region having an output node and including a light sensitive sensor configured to detect a first signal and an analogue to digital converter coupled to the output node. A second region may be switchably coupled to the first region based on a first control signal to the first region. The second region may include a storage device configured to store a signal based on the detection of the first signal. The second region may include an output node coupled to the sensor. The second may be configured to provide a compensation signal based on the stored signal to the light sensitive sensor during detection of a second signal.
