摘要： Systems and methods of automatically selecting a focus range in cameras are disclosed. In an exemplary implementation, a method for selecting a focus range to auto-focus a camera may include receiving focus data for different lens positions in a first focus range. The method may also include analyzing the focus data from the first focus range for focus data extending from the first focus range into at least a second focus range. The method may also include auto-focusing a camera lens using focus data in the first focus range if no focus data extends from the second focus range into the first focus range. The method may also include auto-focusing the camera lens using focus data in the second focus range if focus data in the second focus range extends into the first focus range.

摘要： A digital imaging device, such as a digital camera, minimizes shutter lag by determining some capture parameters, such as focus and exposure settings, before a user of the device has indicated that a photograph is to be taken. The parameters are updated when the device becomes substantially still before the indication that a photograph is to be taken.

摘要： The shutter of a digital imaging device may be calibrated by comparing a characteristic of two separate exposures obtained from a single field of the device's imaging sensor during a single exposure cycle. Calibrating the shutter in this manner facilitates the accuracy of even very short exposure times.

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。

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.
