보다 사실적인 표현을 얻으려면 더 높은 프레임 속도가 필수적입니다. 프레임 레이트를 높이면 전체 정보량이 늘어나므로 효율적인 코딩 방법이 필요합니다. 그러나 충분히 강력한 인코더를 설계하는 데 필요한 이러한 데이터의 통계적 특성은 명확하지 않습니다. 높은 프레임 속도 시퀀스 인코딩에 대한 기존 연구에서는 셔터가 열려서 생성되는 모션 블러의 인코딩 비트 속도에 미치는 영향을 고려하지 않습니다. 촬상장치의 셔터 개방 간격이 커지면 모션 블러(Motion Blur)가 발생하는데, 이를 적분 현상이라고 한다. 적분 현상은 비디오 신호의 통계적 특성을 변경합니다. 이 논문은 프레임 속도가 높은 비디오에 대해 프레임 속도와 비트 속도 사이의 관계를 정량화하는 수학적 모델을 도출합니다. 이는 열린 셔터에 의해 유도된 저역 통과 필터링의 효과를 통합합니다. 코딩 실험은 수학적 모델의 타당성을 확인합니다.

Abstract: Higher frame-rates are essential in achieving more realistic representations. Since increasing the frame-rate increases the total amount of information, efficient coding methods are required. However, the statistical properties of such data, needed for designing sufficiently powerful encoders, have not been clarified. Conventional studies on encoding high frame-rate sequences do not consider the effect on the encoding bit-rate of the motion blur generated by the shutter being open. When the open interval of the shutter in the image pickup apparatus increases, motion blur occurs, which is known as the integral phenomenon. The integral phenomenon changes the statistical properties of the video signal. This paper derives, for high frame-rate video, a mathematical model that quantifies the relationship between frame-rate and bit-rate; it incorporates the effect of the low-pass filtering induced by the open shutter. A coding experiment confirms the validity of the mathematical model.
