Camera having subject maintenance function

A camera having a subject maintenance function, comprising:

• a camera portion;
• a gimbal portion comprising a plurality of rotating means connected to the camera portion and configured to provide a driving force for rotating the camera portion on pitch, roll, and yaw axes;
• and
• a handle portion including a driving controller which performs a stabilizing function by receiving a signal of an angular velocity sensor which senses movements in the three axes of pitch, roll, and yaw and generates a signal corresponding thereto and controlling driving of the plurality of rotating means provided in the gimbal portion, and a general controller configured to control a device overall and an image-capturing mode of the camera,
• wherein the general controller comprises:
• a moving object recognizer configured to recognize a moving object in a video captured by the camera portion in real time;
• a driving compensator configured to track the moving object recognized by the moving object recognizer in real time and perform compensation control for the real-time driving of the plurality of rotating means included in the gimbal portion to locate the moving object to the center of a screen;
• and
• a zooming portion configured to control real-time zoom of the camera portion to maintain the moving object, located to the center of the screen by the driving compensator, to be a constant size in real time.
