Abstract:
The present invention provides non-linear tone mapping apparatus and method and a computer readable medium stored thereon computer executable instructions for performing the method. The non-linear tone mapping apparatus according to the present invention comprises a luminance value computing unit for computing a luminance value of each pixel of an object image using an image information of each pixel; a computing unit for computing a light adaptive value of each pixel using the image information and luminance value of each pixel, the light adaptive value representing the degree of response to brightness of the image in the image information of each pixel; and a converting unit for converting the image information of each pixel of the object image using a ratio of the image information of each pixel to the light adaptive value.
