Disclosed is a camera. The camera further comprises a movement-area detection sensor, wherein the movement-area detection sensor emits electromagnetic wave beam of radio frequency to each of divided setting areas of areas to be photographed so as to receive the reflected wave signals, determines whether a movement is occurred in each of the divided setting areas based on the changes of the reflection speed of each of the received reflected wave signals, and generates movement data based on the previous determination to input the generated movement data in a control unit. Herein, the control unit compresses a series of image frame data from a photographing unit according to movement data obtained from the movement-area detection sensor. |
