ABSTRACT:
An image-processing unit, comprising an exposure conversion circuit, a standard image-setting circuit, a contour extraction circuit, a contour comparison circuit, a final setting circuit, and an image synthesis circuit, is provided. The exposure conversion circuit generates first and second exposure level image data. The standard image-setting circuit sets standard image data. The contour extraction circuit extracts standard and first comparison contours on the basis of the standard image data. The contour comparison circuit detects a first accordance indicator on the basis of the contours. The final setting circuit sets the first conclusive threshold on the basis of the first accordance indicator. The image synthesis circuit generates the rendered image data based on the first conclusive threshold.
