Taxas de quadros mais altas são essenciais para obter representações mais realistas. Como o aumento da taxa de quadros aumenta a quantidade total de informações, são necessários métodos de codificação eficientes. Contudo, as propriedades estatísticas de tais dados, necessárias para projetar codificadores suficientemente poderosos, não foram esclarecidas. Estudos convencionais sobre a codificação de sequências de alta taxa de quadros não consideram o efeito na taxa de bits de codificação do desfoque de movimento gerado pela abertura do obturador. Quando o intervalo aberto do obturador no aparelho de captação de imagem aumenta, ocorre desfoque de movimento, conhecido como fenômeno integral. O fenômeno integral altera as propriedades estatísticas do sinal de vídeo. Este artigo deriva, para vídeo com alta taxa de quadros, um modelo matemático que quantifica a relação entre taxa de quadros e taxa de bits; incorpora o efeito da filtragem passa-baixa induzida pelo obturador aberto. Um experimento de codificação confirma a validade do modelo matemático.

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.
