OPTICAL DETECTING DEVICE AND RELATED METHOD OF SYNCHRONIZATION ADJUSTMENT |
| 摘要 |
A method of synchronization adjustment is applied to an optical detecting device, so as to synchronize an exposure timing sequence of an image detector with a light emitting timing sequence of an indicating light source. The method includes acquiring a continued image set, analyzing intensity of each image of the continued image set, and adjusting the exposure timing sequence according to duty cycle of the image detector and intensity ratio of at least two images. An exposure frequency of the image detector is greater than a flickering frequency of the indicating light source. |

1. A method of synchronization adjustment applied to an optical detecting device for synchronizing an exposure timing sequence of an image detector with a light emitting timing sequence of an indicating light source, the method comprising:
acquiring a continued image set; analyzing intensity of each image of the continued image set; and adjusting the exposure timing sequence according to intensity ratio of at least two images and a duty cycle of the image detector; wherein an exposure frequency of the image detector is substantially greater than a flickering frequency of the indicating light source. |
