13 Claims

1. A method of automatically obtaining a photo of a moment, the method comprising:

obtaining a plurality of image frames sequentially captured through a camera for a preset time interval;

detecting at least one image frame among the plurality of image frames in which a main object corresponding to a preset main object or an action of the main object corresponding to a preset action is recognized;

determining a type of composition of the at least one image frame;

cropping a region including the main object from the at least one image frame based on placement of objects in the determined type of composition;

predicting an aesthetic estimation score of a cropped image frame including the cropped region by inputting the cropped image frame into a first deep neural network model;

adjusting at least one of image quality parameters of the cropped image frame based on the predicted aesthetic estimation score; and

obtaining the photo using the cropped image frame of which the at least one of the image quality parameters is adjusted.
