REAL-TIME DIGITAL IMAGE PROCESSING ARCHITECTURE
First Claim
1. A digital image processing device (100) for real-time evaluation of a sequence of image frames (It) provided by a camera (101), comprising:
- a) a digital pixel processing unit (112) for determining at least one characteristic parameter (Ei, σ
′
i) of a set of processing spots (PSi, PSa, PSb) in the image area from a stream of image values (I(x,y,t));
b) a higher-level digital control unit (130) in communication with the pixel processing unit (112) for setting the set of processing spots and for reading out and post-processing the determined characteristic parameters.

Abstract
The invention relates to a digital image processing architecture, particularly for processing digital images provided by a camera (101) of a biosensor reader (100). The architecture comprises a pixel processing unit (112) for evaluating a stream of image values (I(x,y,t)) with respect to a given set of processing spots (PSi(t) in the image area, thus determining characteristic parameters like the integral (Ei(t) of pixel values in the processing spots (PSi(t). The pixel processing unit (112) communicates with a higher-level digital control unit (130) that sets the processing spots (PSi(t) to be evaluated and that reads out and post-processes the results of the pixel processing unit (112).
