本發明公開一種書籤影格的生成方法、自動生成書籤的影音播放裝置及其使用者介面。依據“重要影格的呈現,應有讓人細讀的時間”的概念提出書籤影格的生成方法包括:從一影片中擷取依時間排序的多個影格;計算該些影格中,兩相鄰影格間的結構相似度;當該些影格中的一第一影格與其相鄰之一第二影格的結構相似度小於一預設值,且該第一影格之後且於一預設時間內的所有影格對應的結構相似度皆大於或等於該預設值時,則將該第二影格指定為一書籤影格;以及儲存該書籤影格的影像及其出現時間。 The presentation of important frames should allow time for careful reading The present invention discloses a method for bookmark frame generation, a video player device with automatic generation bookmarks, and a user interface thereof. Based on the concept that "The presentation of important frames should allow enough time for careful reading", the method for bookmark frame generation includes: extracting a plurality of frames ordered by time from a movie; calculating the structural similarity between two adjacent frames in the frames; when the structural similarity of a first frame in the frames with an adjacent second frames is less than a preset value, and the structural similarity of all the frames corresponding to the first frame and within a preset time is greater than or equal to the preset value, the second frame is designated as a bookmark frame; and storing the bookmark frame and its occurrence time.
