1. A moving image extracting apparatus comprising: a blur value obtaining unit to obtain a blur value which indicates a blur degree of each frame constituting a moving image; a segment determining unit to discriminate the moving image between a stable segment of which variance of the blur values obtained by the blur value obtaining unit is lower than a first value and an unstable segment which is not the stable segment; and an extracting unit to perform segment extraction from the moving image based on the stable segment or the unstable segment obtained by the segment determining unit.
