Problems solved by technology
However, since this case simply adopts the usual hierarchical method or adopts the method set according to the Bayesian (Bayesian) model, the length of the video stream is long and the number of required groups is small, and the setting model is not applied. In the case of video streaming, or in the case of classifying frames with high similarity into different groups
In particular, if the latter problem arises in cases where the number of representative frames required is very small, the user cannot rely on the provided video excerpt function since the summary may include many similar frames

Embodiment Construction
[0044] Hereinafter, the invention will now be described more fully with reference to the accompanying drawings, in which embodiments of the invention are shown.
[0045] figure 1 It is a block diagram of an apparatus for extracting a plurality of frames according to an embodiment of the present invention, and the apparatus can extract a video stream. refer to figure 1 , the device includes a representative frame selector 10 , a frame digest generator 20 , a user interface unit 30 , a video stream decoder 40 , a video storage unit 50 , and a display unit 60 .
[0046] The representative frame selector 10 receives the decoded video stream from the video stream decoder 40 and selects a number of representative frames equal to the predetermined number of representative frames supplied from the frame digest generator 20 . The frame digest generator 20 provides a predetermined number of representative frames designated by the user to the representative frame selector 10 , receives...

A method and apparatus for summarizing a plurality of data select representative frames out of a plurality of frames and summarize the representative frames, in an image reproducing system. The method includes: receiving a video stream and extracting a keyframe for each shot; selecting a predetermined number of representative frames from the keyframes corresponding to the shots; and outputting a frame summary using the representative frames, and comprises: receiving still images and selecting a predetermined number of representative frames; and outputting a frame summary using the selected representative frames. The apparatus includes: a representative frame selector receiving a video stream and selecting representative frames; and a frame summary generator summarizing the video stream using the selected representative frames and outputting a frame summary and frame information, and comprises: a representative still image selector receiving still images and selecting a predetermined number of representative frames; and a still image summary generator summarizing the still images using the selected representative frames and outputting a frame summary and frame information.
Description
technical field [0001] The present invention relates to an image reproduction method and device, and more particularly to a method and device for extracting a plurality of frames, which classifies a plurality of frames and outputs a frame summary by selecting a representative frame from the classified frames . Background technique [0002] Generally, an image reproducing apparatus that plays back a still image or a video stream stored in a storage medium for a user to view through a display device has a function of decoding encrypted image data and outputting the decoded image data. Recently, networks, digital storage media, and image compression / decompression technologies have been developed. Therefore, devices that store digital images in storage media and reproduce the digital images have become widespread. [0003] When storing many digital video streams or still images in a large-capacity storage medium, it is easy and fast to select an image that the user desires to ...
