Method for creating high dynamic range image |
摘要 |
A method for improving the dynamic range of a captured digital image, the method includes the steps of acquiring at a first and second image each at different effective exposures; computing from the first and second images a linear exposure shift; applying the exposure shift to the first image to match relative effective exposure of the second image; and computing a single high dynamic range image from the first and second images. |
