摘要：Autocorrelation coefficients for three dimensions defined by the horizontaldirection, the vertical direction, and the time direction of evaluation target moving imagedata are acquired. A plurality of noise amounts are calculated by executing frequency

analysis of the acquired autocorrelation coefficients for the three dimensions andmultiplying each frequency analysis result by a visual response function representing thevisual characteristic of a spatial frequency or a time frequency. The product of theplurality of calculated noise amounts is calculated as the moving image noise evaluationvalue of the evaluation target moving image data.
