Abstract:
1. A digital image-processing device comprising: a) a Bayer sensor; b) an image memory for storing image data from the Bayer sensor, wherein the image data is writable into the image memory, and wherein from the image memory, image data in Bayer format with a length L and a width B is writable continuously into a data buffer; and c) a computational device for i) combining sample values of the image data by means of adders, in each case symmetrically to a central point of one or more (2n+1)×(2n+1) neighborhoods, ii) forming one or more (n+1)×(n+1) matrices from the one or more (2n+1)×(2n+1) neighborhoods, iii) calculating, by means of an adder network, a first color component based on the one or more (n+1)×(n+1) matrices, and iv) forming, by convolution with a convolver, at least one n×n matrix from the one or more (n+1)×(n+1) matrices.
