摘要： A method comprises detecting edges in at least a region of a captured focus image, using adjacent pixels of the region to obtain first edge detection results and filtering the first edge detection results. The first filtering comprises comparing differences in pixel contrast in the first edge detection results with a first threshold value and removing the differences in pixel contrast that are less than the first threshold value from the first edge detection results. The method further comprises detecting edges in at least the region, using non-adjacent pixels of the region to obtain second edge detection results and filtering the second edge detection results. The second filtering comprising comparing differences in pixel contrast in the second edge detection results with a second threshold value and removing the differences in pixel contrast that are less than the second threshold value from the second edge detection results.

摘要： Auto-focus in a digital camera is improved by stabilizing successive images. Each auto-focus image is correlated to previous images so that scene movement or motion can be tracked. The area in the scene where focus figure-of-merit is computed is adjusted according to the amount of scene movement. Also, two separate focus frames may be compared to determine the direction and speed of the motion. This improves the accuracy of the focus figure-of-merit which results in fewer autofocus failures.
摘要翻译：通过稳定连续的图像，可以提高数码相机的自动对焦。每个自动对焦图像与先前的图像相关，以便可以跟踪场景移动或运动。根据场景移动量调整计算焦点品质因数的场景区域。此外，可以比较两个单独的焦点帧以确定运动的方向和速度。这提高了聚焦优点的精确度，从而导致更少的自动对焦故障。
