METHODS FOR GENERATING HDR (HIGH DYNAMIC RANGE) IMAGES AND APPARATUSES USING THE SAME |
| 摘要 |
A method for generating HDR (High Dynamic Range) images, performed by a processing unit, is introduced to at least contain: acquiring a frame 0 and a frame 1; calculating a first MV (Motion Vector) between the frame 0 and the frame 1; acquiring a frame 2; predicting a second MV between the frame 0 and the frame 2 according to the first MV, a time interval between shooting moments for the frames 0 and 1 and a time interval between shooting moments for the frames 0 and 2; generating a first MD (Motion Detection) matrix comprising a plurality of first MD flags according to the second MV; and fusing the frame 0 with the frame 2 according to the first MD flags. |

1. A method for generating HDR (High Dynamic Range) images, performed by a processing unit, the method comprising:
acquiring a frame 0 and a frame 1; calculating a first MV (Motion Vector) between the frame 0 and the frame 1; acquiring a frame 2; predicting a second MV between the frame 0 and the frame 2 according to the first MV, a time interval between shooting moments of the frames 0 and 1 and a time interval between shooting moments of the frames 0 and 2; generating a first MD (Motion Detection) matrix comprising a plurality of first MD flags according to the second MV; and fusing the frame 0 with the frame 2 according to the first MD flags. |
