Method and device for processing image on basis of artificial neural network

An image processing apparatus, comprising:

• a communication interface configured to receive an input image;
• and
• a processor configured to separate the input image into a foreground image including a subject and a background image including remaining objects except for the subject, estimate camera framing for the subject based on the input image and the foreground image, extract an optical flow map from the input image, configure a feature vector based on the optical flow map, and estimate camera work using the feature vector,
• wherein the communication interface is further configured to output at least one selected from between the camera framing and the camera work.
