APPARATUS AND METHOD FOR PROCESSING IMAGE |
摘要 |
An apparatus and method for processing an image by a wide dynamic range (WDR) process, and for obtaining an image having a wide dynamic area by using a WDR process. The method includes: receiving a long exposure image and a short exposure image having different exposure times; detecting a motion artifact area that may be occur when the long exposure image and the short exposure image are fused; generating a non-linear gain control short exposure image by non-linearly adjusting a gain of the short exposure image such that a luminance component of the short exposure image corresponds to a luminance component of the long exposure image; compensating for motion in the non-linear gain control exposure image based on the detected motion artifact area; and fusing the non-linear gain control short exposure image and the long exposure image to output an image to which a WDR process is performed. |

1. An image processing apparatus comprising:
an image input unit configured to receive a long exposure image and a short exposure image that have different exposure times; a motion artifact area detecting unit configured to detect a motion artifact area resulting from a fusion of the long exposure image and the short exposure image; a non-linear gain adjusting unit configured to generate a non-linear gain control short exposure image by non-linearly adjusting a gain of the received short exposure image, wherein the adjusting adjusts a luminance component of the short exposure image to correspond to a luminance component of the long exposure image, and the non-linear gain adjusting unit is further configured to compensate for motion in the generated non-linear gain control short exposure image based on the detected motion artifact area; and a fusing unit configured to fuse the non-linear gain control short exposure image and the long exposure image to output an image to which a wide dynamic range (WDR) process is performed. |
