Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
173 words
The method of modifying a previously recorded motion picture scene, comprising in combination the steps of deriving from each frame of the recorded motion picture scene a video record of the same, deriving and storing in a computer a plurality of image element digital video values and associated image element addresses that represent the video record, displaying at least a portion of a selected frame, under control of the video values, selecting in the display a picture area bounded by a change of luminosity or hue and representing an object to be modified, storing in the computer a series of boundary addresses that enclose the addresses for the selected picture area, programming the computer to generate and store corresponding series of boundary addresses for respective successively adjacent frames of the scene, programming the computer to perform for each frame a designated modification of only those video values having addresses enclosed by the series of stored boundary addresses, and recording the so modified and any unmodified video values as a modified motion picture scene.
Claim 2
Independent Claim
173 words
The method of modifying a previously recorded motion picture scene, comprising in combination the steps of deriving from each frame of the recorded motion picture scene a video record of the same, deriving and storing in a computer a plurality of image element digital video values and associated image element addresses that represent the video record, displaying at least a portion of a selected frame, under control of the video values, selecting in the display a picture area bounded by a change of luminosity or hue and representing an object to be modified, storing in the computer a series of boundary addresses that enclose the addresses for the selected picture area, programming the computer to generate and store corresponding series of boundary addresses for respective successively adjacent frames of the scene, programming the computer to perform for each frame a designated modification of only those video values having addresses enclosed by the series of stored boundary addresses, and recording the so modified and any unmodified video values as a modified motion picture scene.
Claim 3
Dependent Claim
67 words
The method defined in claim 1, and in which said computer generation of boundary addresses includes comparing for each successive frame the stored video values for rows of addresses that extend transversely of the boundary at points corresponding to respective recorded boundary addresses of the previous frame, and selecting for each row the address that meets a predetermined relation derived from said change of luminosity or hue.
Claim 4
Dependent Claim
54 words
The method defined in claim 1, and in which said computer modification of the video record comprises computing a predetermined function of the video record values for a plurality of image element addresses adjacent each said enclosed address, and modifying the video record value at that enclosed address in accordance with such computed function.
Claim 5
Dependent Claim
57 words
The method defined in claim 1, and in which said computer modification of the video record comprises computing a predetermined function of the video record values at a group of image element addresses external of each series of stored boundary addresses, and modifying the video record values at said enclosed addresses in accordance with such computed function.
Claim 6
Dependent Claim
76 words
The method defined in claim 1, and in which said computer modification of the video record comprises designating for each frame to be modified a reference frame in which said object is positioned in non-overlapping relation to its position in the frame to be modified, and replacing the video record value at each said enclosed address in each frame to be modified by the video record value at the corresponding address in the designated reference frame.
Claim 7
Dependent Claim
76 words
The method defined in claim 1, and in which said computer modification of the video record comprises computing for each image element within an object a relative address representing the position of the image element relative to the series of boundary addresses for each frame, and replacing the video value at each relative address in each frame by a predetermined function of the video values at the same relative address in a series of adjacent frames.
