Abstract
A digital camera capable of variably setting a frame rate may include an imaging device which outputs a plurality of temporally continuous image frames when photographing a moving image. The digital camera may also include a digital signal processor that determines a frame rate with which the image frames are filed, wherein the digital signal processor variably determines the frame rate according to a motion speed of a subject in the frames. The digital camera may further include a recording medium in which the filed image frames are stored. Accordingly, as the frame rate is varied according to the motion of a subject, the motion of the subject can be smoothly realized in a high motion speed section from a reproduction perspective, and substantially repeated image frames can be removed in a low speed motion section. Thus, the size of moving image files can be reduced, saving memory resources.
