METHOD AND SYSTEM FOR PROCESSING VIDEO SIGNALS, FOR EXAMPLE FOR DISPLAYING ON A SMALL SIZED COLOR DISPLAY, AND CORRESPONDING COMPUTER PROGRAM PRODUCT

A method of processing digital video signals produced by a sensor that are to be presented on a viewfinder, the method involving: a first pair of processing operations for scaling and color interpolation; and a second pair of processing operations for the formation of a color matrix and for white balancing. The operations of at least one, and preferably of both of the pairs of processing operations are executed in a single step. The operation of white balancing is moreover performed only for one frame out of K frame in the frame sequence. The preferential application is in the construction of viewfinders for videocameras and digital still cameras.
