    摘要: The invention relates to a microcontroller circuit, comprising circuit elements arranged on a semiconductor body. In order to make a tentative forgery of such a microcontroller circuit at least more difficult, at least a number of the co-operating circuit elements is provided on the semiconductor body in an irregularly scrambled spatial configuration.

    摘要: An image processing device includes an image data correction unit for correcting multi-level image data of a target pixel; an image data binarizer for binarizing the corrected multi-level image data of the target pixel; a binarization error calculator which calculates a first error between the corrected multi-level image data and the image data of pixels within a first region on a periphery of the target pixel that is binarized by the image data binarizer; and a device for executing a predetermined filtering process on the first error to calculate a second error, and for weighting and averaging the second error for pixels within the first region; wherein the image data correction unit corrects the multi-level image data by using the weighted and averaged second error.
