Digital zooming may be enhanced by computationally expensive algorithms which sometimes involves artificial intelligence. It is accomplished electronically, so no optical resolution is gained. It is accomplished by cropping an image down to an area with the same aspect ratio as the original, and scaling the image up to the dimensions of the original. Typically, the digital zoom is not available until the optical zoom has been exhausted.ĭigital zoom is a method of decreasing the precise angle of view of a digital photograph or video image. No quality is lost however, with the lens zoomed-in optically for the bottom photo. Digital zoom has been used to create the middle photo from within the top photo.
