Abstract
A device for reading out image data of a sub-range of an image captured by an image sensor is described, the image sensor including a plurality of image sensor elements which can be read out by an activation signal sequentially appliable to same according to a predetermined clock signal, wherein the image sensor elements outputting the image data for the sub-range can be determined by means of an activation pattern. The device comprises a plurality of branch blocks connected in series storing the activation pattern, wherein each of the branch blocks, depending on the activation pattern, applies the activation signal received to one or several image sensor elements associated with a branch block or passes same on to a subsequent branch block or a terminating element. The activation pattern is stored in the branch blocks substantially simultaneously to the activation signal. No delay or latency times, respectively, occur in the sensor readout.
