    摘要： Automated zoom control and/or automated wide angle capture for digital camera systems and related methods. The camera is configured to have imaging apparatus that selectively couples images from an image scene to an image sensing apparatus that senses the coupled images. A processor implements an automated zoom control function that automatically records a plurality of closely related images having different zoom levels sensed by the image apparatus, and from which a user selects images for storage.

    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.
