Dynamic image processing method, electronic device, and terminal device connected thereto

A dynamic image processing method is executed by an electronic device communicating with a photographing device and reading an executable code to identify a preset object by using artificial intelligence, and perform dynamic image processing for the preset object. The method includes the steps of identifying the preset object, image filtering and forming a concatenated video. In the step of image filtering, a filter condition is set, the filter condition includes detecting a movement variable of the preset object in the initial image, and when the filter condition meets a threshold, a catch moment in the initial image is selected. In the step of forming a concatenated video, at least one video clip in the initial image is selected according to the catch moment, and the video clip is assembled to form the concatenated video. The present disclosure also provides an electronic device and a terminal device.
