Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 画面内部の動きに影響されないでシーン変化 の判定ができるシーン変化検出方法とその装置、及び画 像内容の把握し易いブラウジングや、正確なテープ位置 合わせの可能な動画像編集装置を提供すること。 【構成】 固定ブロック及び移動ブロックを設定するブ ロック位置設定部11と、前フレームの固定ブロックのヒ ストグラム及び後フレームの移動ブロックのヒストグラ ムを算出するヒストグラム算出部12と、それらヒストグ ラム間の相関値を算出する相関値算出部14と、算出され た相関値のうち最も高い相関値を固定ブロック毎に求め るマッチング部15と、求めた相関値のうち高い方からの 所定個数の相関値に基づき、全画面相関値を算出する全 画面相関算出部16と、全画面相関値に基づき、シーン変 化有りと判定するシーン変化判定部17とを備える。 (57) [Summary] [Purpose] A scene change detection method and device that can determine scene changes without being affected by movements inside the screen, and browsing that makes it easy to grasp the image contents, and movies that enable accurate tape positioning. To provide an image editing device. [Structure] A block position setting unit 11 that sets a fixed block and a moving block, a histogram calculation unit 12 that calculates a histogram of a fixed block of a previous frame and a histogram of a moving block of a subsequent frame, and a correlation value between those histograms is calculated. Correlation value calculating unit 14, a matching unit 15 that obtains the highest correlation value among the calculated correlation values for each fixed block, and based on a predetermined number of correlation values from the highest correlation value, the entire screen A full-screen correlation calculation unit 16 that calculates a correlation value and a scene change determination unit 17 that determines that there is a scene change based on the full-screen correlation value are provided.
