1. A digital image processing device for real-time evaluation of a sequence of image frames provided by a camera comprising:
- a memory;
a digital pixel processing unit configured to determine characteristic parameters of a set of processing spots in an image area from a stream of image values, and store the characteristic parameters in the memory; and
a digital control unit in communication with the pixel processing unit, wherein the digital control unit is configured to set the set of processing spots for use by the digital pixel processing unit for determining the characteristic parameters of the set of processing spots, and wherein the digital control unit is further configured to read out from the memory and post-process the characteristic parameters determined by the digital pixel processing unit.

Abstract
A digital image processing device processes digital images provided by a camera of biosensor reader. The device includes a pixel processing unit for evaluating a stream of image values with respect to a given set of processing spots in the image area, thus determining characteristic parameters like the integral of pixel values in the processing spots. The pixel processing unit communicates with a higher-level digital control unit that sets the processing spots to be evaluated and that reads out and post-processes the results of the pixel processing unit.
