Abstract: High dynamic range imaging includes first image data captured using a first image sensor and a first exposure time, using a rolling shutter such that different lines within the first image data are captured at different times. Two or more instances of second image data are captured using second image sensors and second exposure times that are shorter than the first exposure time. The second image data are captured using a rolling shutter, and overlap at least in part with the first image data. A line of the first image data has a corresponding line in each instance of second image data, and the corresponding instances of second image data are captured at different second capture times. For a line in the first image data, the corresponding line from the instance of second image data is selected to be merged with the line in the first image data.

Abstract: A method performed in a processing unit for finding settings to be used in relation to a sensor unit connected to the processing unit is disclosed. The method comprises inter alia receiving, from the sensor unit, a first identifier identifying a type of the sensor unit, and a second identifier identifying a group of at least one related type of sensor unit. If no settings associated with the first identifier are stored in the processing unit, but settings associated with the second identifier are stored in the processing unit, the processing unit uses the settings associated with the second identifier in relation to the sensor unit.
