Abstract:
An image processing method and apparatus employ wide dynamic range imaging. The image processing method includes: providing a radiance map; decomposing a luminance value of the radiance map into a base layer and a detail layer; generating a weight using a ratio between the luminance value of the radiance map and the base layer; creating a compressed luminance using the base layer, the detail layer, and the weight; and generating a tone-mapped image using a color value of the radiance map, the luminance value of the radiance map, and the compressed luminance value. The image processing method provides a display image with enhanced local contrast and details.
