Abstract
Abstract In an image processing apparatus adapted for imparting motion or movement to an input image according to this invention, position data indicating positions of an image in respective key frames are stored to form, by interpolation processing, locus data indicating a movement path of the input image on the basis of the position data and modulated time data subjected to modulation in a time base direction to implement motion or movement processing of the input image on the basis of the locus data.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
An image processing apparatus for imparting movement to an input image comprising a plurality of frames, comprising: position setting means for outputting position data indicating positions of an input image in respective key frames; memory means for storing the position data output by said position setting means; time data generator means for outputting time data representing a time base; time base modulator means for modulating the time data delivered from said time data generator means such that the time base represented by the modulated time data varies in accordance with a predetermined function; interpolator means for forming, by interpolation processing, locus data indicating a movement path of the input image on the basis of the position data stored in said memory means and the modulated time data delivered from said time base modulator means; and image data processing means for implementing movement processing of the input image on the basis of the locus data delivered from said interpolator means and a time signal representing a substantially unvarying time base.
Claim 2
Dependent Claim
169 words
An image processing apparatus for imparting movement to an input image comprising a plurality of frames, comprising: position setting means for outputting position data indicating positions of an input image in respective key frames; memory means for storing the position data output by said position setting means; time data generator means for outputting time data representing a time base; time base modulator means for modulating the time data delivered from said time data generator means such that the time base represented by the modulated time data varies in accordance with a predetermined function; interpolator means for forming, by interpolation processing, locus data indicating a movement path of the input image on the basis of the position data stored in said memory means and the modulated time data delivered from said time base modulator means; and image data processing means for implementing movement processing of the input image on the basis of the locus data delivered from said interpolator means and a time signal representing a substantially unvarying time base.
Claim 3
Dependent Claim
41 words
An image processing apparatus as set forth in claim 1, wherein said predetermined function comprises at least one function pattern indicating a change of a moving speed of said input image are preset in advance in said time base modulator means.
Claim 4
Independent Claim
113 words
A method for imparting movement to an image comprising a plurality of frames, comprising the steps of: producing position data indicating positions of said image in respective key frames; storing the position data; producing time data representing a time base; modulating the time data such that the time base represented by the modulated time data varies in accordance with a predetermined function; forming, by interpolation processing, locus data indicating a movement path of the image on the basis of the stored position data and the modulated time data; and implementing movement processing of the input image on the basis of the locus data and a time signal representing a substantially unvarying time base.
Claim 5
Independent Claim
113 words
A method for imparting movement to an image comprising a plurality of frames, comprising the steps of: producing position data indicating positions of said image in respective key frames; storing the position data; producing time data representing a time base; modulating the time data such that the time base represented by the modulated time data varies in accordance with a predetermined function; forming, by interpolation processing, locus data indicating a movement path of the image on the basis of the stored position data and the modulated time data; and implementing movement processing of the input image on the basis of the locus data and a time signal representing a substantially unvarying time base.
Claim 6
Dependent Claim
25 words
The method of claim 3, wherein said predetermined function comprises at least one function pattern indicating a change of a moving speed of said image.
