1. A method for image processing by an electronic device comprising: detecting a rectangular image region (RIR) in one of a plurality of images while the plurality of images is being received; obtaining a coordinate corresponding to the detected RIR; storing in a memory the coordinate and a first link associating the coordinate with the image in which the RIR is detected; determining a first view angle of the image in which the RIR is detected; determining whether the first view angle is substantially identical to a second view angle of another of the plurality of images; and when the first view angle is substantially identical to the second view angle, storing a second link associating the coordinate with the another of the plurality of images, wherein the determination of whether the first view angle is substantially identical to the second view angle is based at least on one of: a comparison of a first focal length of the image in which the RIR is detected and a second focal length of the another of the plurality of images, and a determination that the electronic device has not moved for a predetermined time period.
