Image data editing
View Patent ↗A computer based image data processing system reads image data from a framestore and processes this data in response to user commands. In order to effect these commands the user is provided with a graphical user interface. In the interface a first region is displayed in which a number of clips representing an output sequence are represented by clip regions on a timeline, along with transitions between the clips which are represented by edit regions. The interface also displays a pointer that is arranged to move over the timeline, and a second region representing input controls. The controls relate to transition operations when the pointer is located over an edit region, and relate to other functions when the pointer is not located over an edit region.
1. Image data editing apparatus, comprising frame storage means storing a plurality of clips, processing means, manually operable input means and display means, wherein said display means is configured to display:
(a) a first region in which a plurality of said clips representing an output sequence are represented by clip regions on a timeline, and transitions between said clips are represented by edit regions;
(b) a timeline cursor configured to be moveable over said timeline,
(c) a second region representing input controls, wherein said controls relate to transition operations when said timeline cursor is located over an edit region, and said controls relate to other functions not including said transition operations when said timeline cursor is not located over an edit region.
2. Image data editing apparatus according to claim 1 , wherein said second region represents a portion of said first region and shows individual frames of said output sequence.
3. Image data editing apparatus according to claim 1 , wherein said display means is configured to move said timeline cursor over said timeline when said output sequence is being played, and said timeline cursor is located when said output sequence stops being played.
4. Image data editing apparatus according to claim 3 , wherein said output sequence is stopped by inputs received at said manually operable input means.
5. Image data editing apparatus according to claim 1 , wherein said timeline cursor is moved and located in response to inputs received at said manually operable input means.
6. Image data editing apparatus according to claim 1 , wherein said first region comprises a plurality of timelines; said apparatus is configured to receive a manual input identifying a selection of one of said timelines, and said timeline cursor is located by said selection of one of said timelines.
7. Image data editing apparatus according to claim 1 , wherein said manually operable input means are arranged to receive inputs indicating that display of said output sequence is required, and said display means are arranged to display said output sequence in dependence of receiving said inputs, such that if said timeline cursor is located at a transition when said input is received only a portion of said output sequence which has a duration dependent upon the duration of the transition and which comprises said transition is displayed.
8. Image data editing apparatus according to claim 1 , wherein said controls relating to transition operations includes controls for cut positions, dissolve parameters or wipe parameters.
9. Image data editing apparatus according to claim 1 , wherein said controls relating to other to other functions comprises controls to modify effects.
10. Image data editing apparatus according to claim 1 , wherein said controls to modify effects includes controls for gamma adjustments.
11. A method of editing image data comprising the steps of:
storing a plurality of clips in a frame storage means;
receiving manually generated inputs; and
displaying
(a) a first region in which a plurality of said clips representing an output sequence are represented by clip regions on a timeline, and transitions between said clips are represented by edit regions;
(b) a timeline cursor configured to be moveable over said timeline,
(c) a second region representing input controls, wherein said controls relate to transition operations when said timeline cursor is located over an edit region, and said controls relate to other functions not including said transition operations when said timeline cursor is not located over an edit region.
12. A method of editing image data according to claim 11 , wherein said second region represents a portion of said first region and shows individual frames of said output sequence.
13. A method of editing image data according to claim 11 , comprising the steps of:
moving said timeline cursor over said timeline while displaying a play back of said output sequence;
and stopping said play back of said output sequence so that said timeline cursor is located at a position on said timeline.
14. A method of editing image data according to claim 13 , wherein said output sequence is stopped in dependence of receiving said manually generated inputs.
15. A method of editing image data according to claim 11 , wherein said timeline cursor is moved and located in response to received manually generated inputs.
16. A method of editing image data according to claim 11 , wherein said first region comprises a plurality of timelines; and said method comprises the steps of:
receiving a manual input identifying a selection of one of said timelines; and
identifying said timeline cursor as being located at an edit region in response to receiving said manual input identifying a selection of one of said timelines.
17. A method of editing image data according to claim 11 , comprising the steps of:
receiving inputs indicating that display of said output sequence is required; and
displaying said output sequence in dependence of receiving said inputs, such that if said timeline cursor is located at an edit region when said input is received only a portion of said output sequence which has a duration dependent upon the duration of the corresponding transition and which comprises said transition is displayed.
18. A computer-readable medium having computer-readable instructions executable by a computer such that, when executing said instructions, a computer will perform the steps of:
storing a plurality of clips in a frame storage means;
receiving manually generated inputs; and
displaying:
(a) a first region in which a plurality of said clips representing an output sequence are represented by clip regions on a timeline, and transitions between said clips are represented by edit regions;
(b) a timeline cursor configured to be moveable over said timeline,
(c) a second region representing input controls, such that said controls relate to transition operations when said timeline cursor is located over an edit region, and said controls relate to other functions not including said transition operations when said timeline cursor is not located over an edit region.
19. A computer-readable medium according to claim 18 , such that when executing said instructions, a computer will perform the steps of:
moving said timeline cursor over said timeline while displaying a play back of said output sequence; and
stopping said play back of said output sequence so that said timeline cursor is located at a position on said timeline.
20. A computer-readable medium according to claim 18 , such that when executing said instructions, a computer will perform the steps of:
moving said timeline cursor in response to received manually generated inputs, so that said timeline cursor is located.
