Title: IMAGE PROCESSING METHOD, RECORDING MEDIUM, AND IMAGE PROCESSING DEVICE
Abstract:
A brightness component is separated from the electronic data of an image inputted, and the value of the brightness is calculated from the separated brightness component. A smoothing intensity is calculated from the value of the calculated brightness. The preset filter information is selected from the smoothing intensity calculated, so that the electronic data are smoothed on the basis of the filter information. The electronic data thus smoothed are written in a RAM. By calculating the smoothing intensity from the brightness value, a flattening intensity can be changed according to a brightness. Without highlighting the noise of the flat portion, therefore, the noise of the portion of a low brightness, i.e., the dark portion of the image can be eliminated concentratedly.
