The image processing apparatus and method process image data of an original image by compressing a dynamic range of the original image. The apparatus and method process the image data of the original image by continuous filtering with at least two edge preserving smoothing filters having different characteristics to generate blurred image data which represents a blurred image of the original image, and process the image data of the original image by compressing the dynamic range of the original image based on the blurred image data. The apparatus includes a blurred image generating unit for generating the blurred image data and having the at least two edge preserving smoothing filters, and a processing unit for compressing the dynamic range of the original image.
