A method and apparatus for invoking a High Dynamic Range (“HDR”) mode in a camera are disclosed. The method comprises detecting that the camera is operating in a preview mode. The method further comprises determining a dynamic range, Auto Exposure (“AE”) metadata, and a motion level associated with a plurality of frames captured in the preview mode. Finally, the method comprises invoking the HDR mode when each of the determined dynamic range, the AE metadata, and the motion level is above a first threshold value, a second threshold value, and a third threshold value, respectively. |

1. A method for invoking a high dynamic range (“HDR”) mode in a camera, the method comprising:
detecting that the camera is operating in a preview mode; determining a dynamic range, auto exposure (“AE”) metadata, and a motion level associated with a plurality of frames captured in the preview mode, the determining of at least one of the dynamic range, the AE metadata, or the motion level by measuring the dynamic range, the AE metadata, or the motion level, respectively, of the plurality of frames captured in the preview mode; determining, based on the measuring, a stability value of at least one of the dynamic range, the AE metadata, or the motion level; and invoking the HDR mode when each of the determined dynamic range, the AE metadata, and the motion level is above a first threshold value, a second threshold value, and a third threshold value, respectively. |
