Patent Images
1. A noise eliminating apparatus that eliminates noise from input image data, the noise eliminating apparatus comprising:
- a film determining unit that determines whether the image data are originated from film recording;
a strength determining unit that determines a strength at which noise is to be eliminated from the image data based on a result of determination made by the film determining unit; and
a noise eliminating unit that eliminates noise from the image data based on the strength determined by the strength determining unit.

Abstract
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.
