摘要: The invention provides a method for transforming an image from Low Dynamic Range (LDR) obtained with given camera to High (HDR) image, the comprising: obtaining exposure-pixel response curve ( 21 ) said converting LDR HSB color space arrays 22 ), including Hue array, Saturation array and Brigthness array; determining Radiance 23, 24 by inverse mapping each pixel in Brightness using of (f-1).
