ABSTRACT:
TECHNICAL FIELD
The present invention relates to an image displaying method and an editing apparatus.
BACKGROUND ART
When materials recorded on tapes or discs are to be edited, an operation of apparatus for reproducing video and audio data from their storage medium are searched at a high-speed as a shuttle mode to detect the record position of a target scene. Further, the apparatus is put into a so-called jog mode illustratively for frame-by-frame reproduction whereby edit points (in- and out-points) are set. With desired scene thus acquired, the next desired scene is repeatedly detected likewise. In such editing operations, it is customary to use a single video monitor wherein the desired scene is verified using images displayed thereon.
Since a single scene is displayed in the process for detecting a desired scene in the shuttle or jog mode, reproducing position must be changed again and again in the shuttle or jog mode before the optimal scene is reached without keeping in mind which scene is stored on a position of either the tape or the disc. Thus, it takes time to carry out such editing work so that the editing work can not be done efficiently.
It is therefore an object of the present invention to provide an image displaying method and an editing apparatus whereby the optimal scene is reached easily so that recorded materials on the medium can be edited efficiently.
DISCLOSURE OF INVENTION
In carrying out the invention and according to one aspect thereof, there is provided an image displaying method comprising displaying one video clip or a plurality of video clips of temporally continuous material images on a screen as a first image group, displaying on the screen, when one of the video clips is selected from the first image group to request for a more detailed display of the selected video clip, image extracted at an interval of a first time period from the temporally continuous material images constituting the selected video clip as a second image group, displaying on the screen, when one image is selected from the second image group to request for a more detailed display of the selected image, image extracted at an interval of a second time period shorter than that of the first time period as a third image group, the image occurring over a time period before and after, before, or after the selected image within said second image group, then displaying on the screen, when one image is further selected from the image group displayed on the screen to request for a more detailed display of the selected image, image extracted relative to the selected image from the temporally continuous material images at an interval of a time period shorter than that of the image group including the selected image, and displaying on the screen, when one image is selected from an N-th image group to request for a more detailed image of the selected image, continuous material images occurring over a time period before and after, before, or after the selected image within the N-th image group.
According to another aspect of the invention, there is provided an editing apparatus comprising a data reproducing part for reproducing a temporally continuous material to acquire a reproduced signal, an editing part for performing editing process using the reproduced signal acquired by the data reproducing part and for creating reduced image of the material, a display device for displaying a plurality of reduced images of the material created by the editing part, an inputting part for selecting any one of said reduced images displayed on a screen of the display device, and a controlling part for controlling the data reproducing part and the editing part, when any one of the images currently displayed on the display device is selected by the inputting part to request for a more detailed display of the selected image, to allow the display device to display reduced images of the image extracted relative to the selected image from the temporally continuous material at intervals of a time period shorter than that of the reduced images displayed currently on the display. In one preferred structure of the invention, the editing apparatus may further comprise a video monitor, wherein, when the image displayed on the display screen is selected by the inputting part, the controlling part controls the data reproducing part and the editing part to allow video monitor to display the selected material image in a nonreduced format on the screen thereof. Further, in another preferred structure of the invention, the editing apparatus may further comprise an audio outputting part, wherein, when the image displayed on the display screen is selected by the inputting part, the controlling part controls the data reproducing part and the editing part to allow the audio outputting part to output audio data corresponding to the selected image therefrom for a predetermined period of time.
According to the invention, when a temporally continuous material is to be edited, one or a plurality of video clips of images representing the material are displayed. When one of the displayed video clips is selected to request for a more detailed display of the selected clip, reduced images are displayed after being extracted from the temporally continuous material at intervals of a time period shorter than that of the displayed reduced images. When one of the images on display device is further selected for a more detailed display of the selected image, a plurality of reduced images are displayed relative to the selected image at an interval of time period shorter than that of the former. Thus, the process above may select desired images from any positions in the temporally continuous material.
