1. A hard disk recorder comprising: an interface to which a digital video camera capable of photographing a still image and a moving image is connected; a signal processing section for performing compression processing of video data input from the digital video camera through the interface at a variable bit rate by an MPEG encoder; a hard disk for recording the video data subjected to the compression processing by the signal processing section; a bit rate calculation unit for calculating the bit rate of the video data to perform compression processing of the video data input from the digital video camera; a first determination unit for determining whether or not the calculated bit rate is equal to or greater than a predetermined threshold value; a second determination unit for determining whether or not a state in which the bit rate is less than the threshold value continues for a given section or more; and a chapter setting unit for determining that the video from the digital video camera is a still image and setting a chapter in the portion of the still image if the first determination unit determines that the bit rate is less than the threshold value and the second determination unit determines that the state in which the bit rate is less than the threshold value continues for the given section or more.
