Method of generating HDR image and digital image pickup device using the same |
摘要 |
A method of generating a high dynamic range (HDR) image and a digital image pickup device using the same are described. The digital image pickup device is employed to generate an HDR image according to a single digital image. The method includes the steps of obtaining an original image; performing a gray-scale processing to convert the original image into an original gray-scale pattern, in which each pixel in the original gray-scale pattern is assigned with a gray-scale value; performing a conversion procedure according to a gradient and a compensation value of the gray-scale value of each pixel in the original gray-scale pattern, and generating a high dynamic gray-scale pattern by using the gradients and the compensation values; and compensating the original image with the high dynamic gray-scale pattern, so as to generate the HDR image. |
