PURPOSE:To convert a noise to image signal non-dependency and to execute a noise smoothing processing by selecting a conversional expression corresponding to a kind of a film and an aperture size, converting an image signal by the conversional expression, executing various noise reduction processings, and executing a reverse conversion by a reverse conversional expression forming a pair of the conversional expression. CONSTITUTION:This processor is provided with a means 3041 for inputting a kind of a film, means 3043, 3044 for setting an aperture size on the film surface, a means 3039 for storing a conversional expression to various films, and a means 3039 for storing a reverse conversional expression to various films. In this state, a conversional expression corresponding to a kind of a film and an aperture size is selected, an image signal is converted by the conversional expression, various noise reduction processings are executed, and a reverse conversion is executed by a reverse conversional expression forming a pair with the conversional expression. In such a way, a noise can be converted to image signal non-dependency, and various noise smoothing processings can be executed. |
