Abstract

An electronic device includes a data processing system and a set of pixels that each include one or more radiation-emitting electronic components, one or more radiation-sensing electronic components, or any combination thereof. The data processing system that is configured to access data regarding the set of pixels and determine at least one calibration value corresponding to the data. The number of the calibration value(s) is less than the number of the pixels within the set. The data processing system is further configured to compare the calibration value(s) to another value and change at least one adjustment factor if the calibration value(s) differs from the other value by more than a predetermined amount. The number of the adjustment factor(s) is less than the number of the pixels within the set. Data processing system readable media and methods for using the electronic device are also described.
