Abstract:
A method of processing image data comprising a plurality of picture points, said plurality including a group of displayed picture points making up an image, each of said displayed picture points being relocatable in response to manual operation of an interface device, the method comprising:moving a displayed picture point, hereinafter ""identified picture point"", by a displacement in direct response to said manual operation, thereby to define a to-be-performed warp operation;calculating a proportionality distribution function based on said displacement, said proportionality distribution function comprises gaussian distribution; andmoving a number of additional displayed picture points, hereinafter ""related picture points"", said related picture points being fewer than all displayed picture points in said image, said related picture points being included in said group and being related to said identified picture point by a predetermined relation selected from a group consisting of intensity, color and initial unwarped position, said related picture points being moved by a displacement which differs from the displacement of said identified picture point in accordance with said proportionality distribution function, such that the displacement of each related picture point differs from the displacement of said identified picture point in proportion to a distance of said each related picture point from the identified picture point, thereby to perform said to-be-performed warp operation.
