Then the luminance signal is inputted to a low pass filter 112, by which a high frequency component and an intermediate frequency component are cut off. The resulting luminance signal obtained in this way corresponds to a fogged image. The luminance signal is inputted to a dynamic range compression means 113, by which a dynamic range is compressed and the resulting data are synthesized with image data fed to a main path by an image data synthesis means 114. A soft focus image is generated by utilizing the dynamic range conversion means 104 so as to have only to change a parameter singly.
