摘要：
A film determining unit determines whether input image data are originated from a film source. A controller determines a strength at which noise is to be eliminated from the image data based on the result of determination made by the film determining unit. A noise eliminating unit eliminates noise from the image data based on the strength determined by the controller. Specifically, when image data are originated from film-recorded images, the noise elimination strength is decreased so that film grains included in the image data are preserved.
摘要（中）：
电影确定单元确定输入的图像数据是否源自电影来源。 控制器基于由影像确定单元进行的确定结果，从图像数据中确定要消除噪声的强度。 噪声消除单元基于由控制器确定的强度来消除图像数据中的噪声。 具体地，当图像数据来自胶片记录图像时，噪声消除强度降低，从而保留包含在图像数据中的胶片颗粒。
