A computer-implemented method for manufacturing or controlling a technical system includes the method steps: (a) inputting a sample of parameter sets suitable for manufacturing or controlling the technical system, with a feasibility identifier assigned to each of the parameter sets, wherein the feasibility identifier marks each parameter set either as technically feasible or technically non-feasible or erroneous in terms of manufacturing or controlling the technical system, (b) generating a computerized surrogate model for the technical system based on the respective parameter sets of the sample, which are marked as technically feasible, by means of a regression method, (c) determining an optimized parameter set based on the surrogate model by means of a computerized optimization method, and (d) outputting the optimized parameter set for manufacturing or controlling the technical system.

In a method and apparatus for difference measurement of an image, the image is detected by an image sensor array having (N&#xd7;N) sensor elements, wherein N=2, n&#x2267;2, and n being an integer number, each detected sample value is read as a positive or as a negative sample value according to a sign control pattern from a pattern control unit, and measurement values are generated for measurement template blocks of the image sensor array by a computing unit which computes for each measurement template block a weighted sum of the read sample values of the respective measurement template sensor elements depending on a predetermined measurement template. A measurement template block is, provided for at least four adjacent sensor elements of the image sensor array. The method/apparatus can be used in any kind of digital camera and allows for a fast generation of image data with a hardware implementation of low complexity.
