IMAGE PROCESSING DEVICE FOR COLOUR IMAGE DATA AND METHOD FOR PROCESSING COLOUR IMAGE DATA

摘要

The aim of the invention is to provide a more effective conversion of colour image data, said conversion being simplified to such an extent that it can be implemented as hardware. To achieve this, the invention discloses a digital image processing device comprising a Bayer sensor and an image memory, in which the image data of the sensor are written to an image memory and image data is taken from said image memory in Bayer format with a length L and a width B and continuously written to a data buffer, and in which the scanned values are combined using an arithmetic unit with the aid of a digital adder, in each case symmetrically to a central point of one or more (2n+1) x (2n+1) contiguous regions. The arithmetic unit is then used to derive one or more (n+1)x(n+1) matrices from said combination and at least one n x n matrix is formed from said (n+1)x(n+1) matrix or matrices with the aid of additional digital adders. A first colour component is then calculated from the or each n x n matrix with the aid of a digital adder network.
