Patent ID: 7596764

Claim:
Apparatus for processing image data, comprising processing means, memory means, display means and manually operable input means, wherein said memory means stores said image data and instructions, said image data and said instructions configure said processing means to perform the steps of outputting said image data to said display means as a hierarchical structure of image data processing nodes having respective hierarchical properties, said structure being configured with a dimension, wherein said dimension comprises either: (1) a three-dimensional (3D) hierarchical structure representing a top-to-bottom processing pipeline of images based on the image data processing nodes, (2) a two-dimensional (2D) image processing scene graph with image processing functions performed sequentially, or (3) a four-dimensional (4D) timeline view illustrating a total number of processing cycles that have to be performed to output a complete sequence of final output image frames based on a timeline sequence; in response to selecting a plurality of said nodes by way of said input means, generating a multidimensional group node having hierarchical properties processed from said respective properties; replacing said selected plurality of nodes with said group node in said hierarchical structure; and in response to selecting said group node, displaying the selected group node in said hierarchical structure as a different one of the dimensions.
