Following apparatus and following system
First Claim
1. A following apparatus which follows a target object while photographing the target object, the following apparatus comprising:
- a driving apparatus configured to move a main body;
a photographing portion configured to continuously photograph the target object; and
a controller configured to;
obtain an area size value of an identification window of the target object in a live-view motion picture from the photographing portion,obtain a distance value according to the obtained area size value,obtain a sharpness value of the target object in the live-view motion picture from the photographing portion,set a first threshold value with respect to the sharpness value of the target object,when the sharpness value of the target object is not less than the first threshold value, control the driving apparatus to maintain a distance between the photographing portion and the target object at a reference distance value using one method that is based on the obtained distance value, andwhen the sharpness value of the target object is less than the first threshold value, control the driving apparatus using another method that is different from the one method,wherein the other method is based on at least one of a movement distance value of a focus lens and a direction of change of the area size value of the identification window of the target object.

13. A following system comprising:
-
a following apparatus configured to follow a target object while photographing the target object; and a remote control apparatus comprising a display, and configured to remotely control an operation of the following apparatus according to a user input while displaying a motion picture from the following apparatus on the display, wherein the following apparatus; obtains an area size value of an identification window of the target object from a live-view motion picture generated by the photographing, and obtains a sharpness value of the target object in the live-view motion picture, sets a threshold value with respect to the sharpness value of the target object, when the sharpness value of the target object is not less than the threshold value, controls a following speed to maintain a distance with respect to the target object at a reference distance value using one method that is based on the obtained area size value, and when the sharpness value of the target object is less than the threshold value, control the driving apparatus using another method that is different from the one method, wherein the other method is based on at least one of a movement distance value of a focus lens and a direction of change of the area size value of the identification window of the target object. - View Dependent Claims (14, 15, 16)
