Upon enabling an automatic cropping feature, a computer-implemented method for cropping a plurality of images retrieves a number of images to process among the plurality of images, and selects an image from the plurality of images to determine a set of crop values for the image until the set of crop values for each image have been determined. Determining a set of crop values for an image includes scanning the image from a first side to an opposing side to determine for each scan line of the image an amount representing a degree of color variation among the pixels for that scan line. The amount determined for each scan line is then compared to a threshold value until a crop value for a first area of the image can be determined.
