METHOD FOR RESIZING OF A DIGITAL IMAGE

A method of processing a digital image comprising the steps of: PA1 providing an input digital image having an input size; PA1 providing the output size of a desired output digital image; PA1 inputting the provided input digital image and the provided desired output digital image size to a weight estimation sub-system which operates to generate several weight derivative estimates; PA1 inputting the provided input digital image to an x-direction derivative estimation sub-system which produces an array of x-direction derivative estimates; PA1 inputting the provided input digital image, the weight derivative estimates and the x-direction estimates to an x-direction interpolated value estimation subsystem which produces in intermediate digital image which has the same number of rows as said input digital image while having the same number of columns as said output digital image; PA1 operating on said intermediate digital image by a y-direction derivative estimation sub-system to produce y-direction derivative estimates; PA1 inputting the intermediate digital image, the weight derivative estimates, and the y-direction derivative estimates to a y-direction interpolated value estimation sub-system to produce said output digital image.
