Tracking method and device based on electronic holder

Abstract

The invention discloses a tracking method and device based on an electronic holder. The method comprises steps of determining the original coordinate information of a region selection frame in the current display image, predicting a target region where a tracking target in the next frame of to-be-displayed image according to the original coordinate information and the pre-moving direction, and moving the target selection frame to the target region; and receiving the to-be-displayed image grabbed by an image senor of the electronic holder, and finally outputting the target region. According to the invention, it can be achieved that when a user is using a small portable shooting device to carry out shooting, a certain target with the quite quick moving frequency in the frame can be precisely tracked and shot, so the video with the ideal image quality can be shot; user demands can be met; and user experience is improved.
