Summary:To provide a method, a system, and a computer-readable medium that can reduce the computational load of high resolution video processing and transmission band requirements while retaining the essential details of a target region of an image.SOLUTION: A system 400 that analyzes gaze tracking data to determine one or more target regions in an image of a video stream includes a downscaler 405 that selectively scales video stream data such that a section within the target region maintains high resolution and the area that is not within the target region is downscaled to reduce transmission bandwidth costs, and can reduce image sickness by reducing the size of the high-resolution area.SELECTED DRAWING: Figure 4 【課題】画像の関心領域の必須の詳細を保持しながら、送信帯域要件と、高解像度ビデオ処理の計算負荷を低減できる方法、システム及びコンピュータ可読媒体を提供する。【解決手段】視線追跡データを分析して、ビデオストリームの画像内の１つまたは複数の関心領域を決定するシステム４００であって、関心領域内のセクションが高解像度を維持し、関心領域内でないエリアをダウンスケーリングして送信の帯域幅コストを低減するように、ビデオストリームデータを選択的にスケーリングするダウンスケーラ４０５を有し、高解像度エリアのサイズを低減することによる映像酔い低減も可能とする。【選択図】図４
