Digital image processing method, non-transitory computer-readable recording medium having recorded thereon a program for executing the digital image processing method, and digital image processing apparatus
A digital image processing method and apparatus eliminates or reduces the temporal delay associated a perspective transform being generated for a region of an captured image. The method includes: receiving a preview image; detecting at least one rectangular region from the preview image and obtaining coordinate information corresponding to the at least one rectangular region; determining a main rectangular region from among the at least one rectangular region detected from the preview image; capturing an image; and generating a perspective-transformed image by performing perspective transform on the captured image by using coordinate information corresponding to the main rectangular region.
