A region mapping operation having steps as follows is applied to an image using a plurality of region mapping curves for compensating different luminance associated with a plurality of regions in the image. A low frequency image is obtained. A reference value for each region in the image is obtained according to the low frequency image. One region mapping curve is selected according to the reference value of the region. A gain curve is obtained according to the selected region mapping curve, a gain value of a pixel value or a luminance value of the region is obtained according to the gain curve, an adjusted gain value is obtained according to the luminance corresponding to the pixel value, and the pixel value is adjusted according to the luminance value, the gain value, and the adjusted gain value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wide dynamic range imaging method","description":"A method for wide dynamic range imaging is illustrated.
