Hereinafter, declarative description thumbnail image generation method.
Thumbnail image is used for being provided at useful functions such as video browser, generates and program guide such as Description of content, storyboard (storyboard), key frame.Thumbnail image can be exported under the state in being included in the record cell of tabulating in conjunction with the record of Fig. 8 explanation.
Thumbnail image is the image with the particular frame of the video of the size demonstration littler than original size.The application of this thumbnail is different, and this is because thumbnail image can be as the representative image in little picture, the key frame that generates in order to carry out video index or the program guide of the content of summarizing the program that records.
Thumbnail image generation method can be divided into decoding with the frame of the video of MPEG scheme coding and directly reducing the method for the size of decoded frame and the method for using the DC value of figure (I-picture) in the frame.In the previous case, need decode to all pixels of frame.Owing to this reason, need length variable decoder.
Under latter event, because use the DC value of figure in the frame to generate thumbnail image, so do not need length variable decoder.A kind of method in back is also simple.
Thumbnail image is provided for using has the method that the size littler than original image is the content of the representative image of the low resolution specific part of impliedly representing the overall content of video or video.Therefore, for the frame of video as the source of thumbnail image, not preferred the use because for example the video camera of unexpected zoom moves or object moves the unsharp image that forms such as fuzzy that causes, this is the conversion of scene conversion or camera lens causes because thumbnail image should not have noise, blank and overlapping, and the information of the specific part of total body portion of relevant video or relevant video is provided with should be understood that.
If generated thumbnail image at figure in all frames of video, then the amount of the thumbnail image of Sheng Chenging is huge.Therefore, in this case, the burden of storage medium increases.In addition, because the interference of many unwanted thumbnail images, the content that search subscriber is wished is also inconvenient.In addition, because can on a picture, the quantity of thumbnail images shown image be limited, therefore may be difficult to imply effectively the interior perhaps particular video frequency content partly of the overall video section of expression.
In order to address this is that, can use the method that generates thumbnail image according to the sample rate of predetermined sampling rate or user's input with rule at interval.
Can use user's designated partly to be used for generating the another kind of method of thumbnail image.
That is to say, can be by unconditionally generating thumbnail image, realize generation based on the thumbnail image of figure in the frame according to specifying sample rate to generate thumbnail image at interval or generate thumbnail image with the interval of user's appointment with rule for figure in each frame.
Fig. 9 is the flow chart for the method that records operation and generation new record mark that illustrates according to the embodiment of the invention.
