ABSTRACT:
FIELD OF THE ART
The present invention relates to an editing system for editing source video data imaged by a video camera or the like, and more particularly, is suitably applicable to an editing system for editing material to be promptly reported like sports and news broadcasting.
BACKGROUND ART
Heretofore, as this type of editing system, a system using a video tape recorder (hereinafter, it is referred as VTR for short) as recording means for recording edit material has been provided. In this editing system, live images such as sports and news, are sequentially recorded by the VTR, and the recorded images are read out as edit material to edit programs.
In the case of handling the live images such as sports and news, an editing system is required that can rapidly edit to provide exciting images having presence to audience. In the conventional editing system, however, since the VTR is used as a recording medium, a time for head-search, fast-forwarding, or rewinding of the VTR are needed, the VTR must be controlled till immediately before on the air. It causes a problem that editing operation cannot be performed speedy. For example, a tape must be rewound repeatedly to set optimal reproducing speed against material data, thus it takes a long time even when only reproducing speed is set.
Furthermore, in the conventional editing system, when in editing, various devices are needed in addition to VTR: a plurality of monitors to confirm record images and edit images, etc. It causes a problem that system structure becomes larger. Additionally, since various devices must be operated, there is a problem that operation becomes complicated.
As described above, the conventional editing system is not considered to efficiently perform editing work in restricted environments at the scene, and handle materials wanting a real-time characteristic, such as sports broadcasting and a news report; it has been insufficient in usability.
DISCLOSURE OF INVENTION
Considering the above points, the present invention provides an editing system capable of high-speed real-time edition and having further improved usability.
An editing system according to the present invention provides control means for displaying an in-point or an out-point clipped image data of an event formed from a first or a second video data on display means based on an in point or an out point which is specified via user interface means, and setting the reproducing speed of a desired event specified via the user interface means from among events, based on a reproducing speed data inputted via the user interface means.
Since a reproducing speed can be set based on the reproducing speed data supplied via the user interface means against a desired event, for example, slow-playback can be set against the desired event. Thus, further realistic images can be easily generated.
Moreover, an editing system according to the present invention provides control means that when an in point of the first video data is specified via the user interface means, controls to output a reproducing command by which reproducing operation is started from a position fixed time before than the above in point to a main recording/reproducing device and display thus reproduced second video data on display means.
Since when an in point of the first video data is specified, reproducing operation is started from a position fixed time before than the above in point and thus reproduced second video data is displayed on the display means, the in point can be easily corrected while viewing the reproduced second video data even if specifying an in point delayed. Thus usability of the editing system can be improved.
Furthermore, by using a main recording/reproducing device capable of reproducing while recording, recording and reproducing can be performed at the same time and real-time edition can be conducted.
