Patent ID: 8069201

Claim:
An image processing method of a digital processor for generating at least one digital image, utilizing at least one matrix, comprising: (a) transforming, in said digital processor, an 8×8 sample data matrix into an 8×8 intermediate matrix using the 8×8 transform matrix: T 8 × 8 = [ 8 10 10 9 8 6 4 2 8 9 4 - 2 - 8 - 10 - 10 - 6 8 6 - 4 - 10 - 8 2 10 9 8 2 - 10 - 6 8 9 - 4 - 10 8 - 2 - 10 6 8 - 9 - 4 10 8 - 6 - 4 10 - 8 - 2 10 - 9 8 - 9 4 2 - 8 10 - 10 6 8 - 10 10 - 9 8 - 6 4 - 2 ] ; (b) scaling said intermediate matrix using a scaling matrix; and (c) shifting the elements of said scaled intermediate matrix by N bits to yield a transformed matrix, where N is an integer in the range of 13 to 16; wherein said transformed matrix is utilized in manipulating at least a portion of said image and accordingly generating a digital image.
