ABSTRACT:
Image-processing devices and methods are disclosed. Such a device includes an image-input unit, a fluctuation-extraction unit, a modulation-signal-generation unit, a level-compression unit, and a gradation-correction unit. The image-input unit inputs an image. The fluctuation-extraction unit extracts a local-fluctuation component from the input image and generates a local-fluctuation image containing a fluctuation component. The modulation-signal-generation unit produces a modulation signal used for modulating the input image to a local-fluctuation image. The level-compression unit level-compresses the modulation signal. The gradation-correction unit modulates the input image according to the modulation signal after level-compression, thereby producing a gradation-corrected image.
