Beschreibung
Zusammenfassung:	A method for controlling image quality in a wearable image display device disclosed in the present application comprises the operations of: determining a threshold value of gaze movement speed for changing image quality according to the characteristics of a wearable image display device; measuring the gaze movement speed of a user of the wearable image display device; and requesting quality control for a video image to be transmitted according to a comparison result of the gaze movement speed and the threshold value. 본 명세서에 개시된 착용형 영상 표시 장치에서의 영상 품질 제어 방법은 착용형 영상 표시 장치의 특성에 따른 영상 품질 전환을 위한 시선 이동 속력의 임계 값을 판단하는 동작; 상기 착용형 영상 표시 장치의 사용자의 시선 이동 속력을 측정하는 동작; 및 상기 시선 이동 속력과 상기 임계 값의 비교 결과에 따라 전송될 비디오 영상에 대한 품질 조절을 요청하는 동작을 포함한다.
