Method for managing digital slow shutter mode in monitor camera |
摘要 |
<p>Disclosed is a method for managing a DSS (Digital Slow Shutter) mode in a monitoring camera. When an iris of the monitoring camera is maximally opened and a shutter speed is minimum, the DSS mode is set. In the DSS mode, a video frame inputted in a predetermined cycle is stored in a memory. A plurality of video frames stored in the memory are synthesized into a monitoring video frame. The monitoring video frame is outputted irrespective of a luminance thereof. When the memory is full of the video frames, an oldest stored video frame is replaced with a newly inputted video frame. The monitoring video frame can be consecutively outputted in a predetermined cycle even though the monitoring camera operates in the DSS mode. The monitoring video frame based on a bright luminance level can be outputted, such that a monitoring function is enhanced.</p> |
