1. A representative frame selecting system comprising: an importance obtaining unit that obtains a plurality of importance for each frame from calculating on the basis of a length of a similar frame interval formed of consecutive frames, each frame in the consecutive frames having a value that is greater than or equal to a standard, the value being derived according to a similarity between each of the frames included in video information; an evaluation value obtaining unit that obtains a plurality of evaluation values for each frame from calculating on the basis of an evaluation standard from frames adjacent to each frame; and a representative frame selecting unit that selects at least one representative frame among the frames included in the video information, on the basis of the plurality of importance and the plurality of evaluation values for each frame, wherein the representative frame selecting unit selects a next representative frame after reducing an evaluation value with respect to a frame which is similar to the representative frame selected before, and wherein, in a case of selecting two representative frames, the evaluation value obtaining unit obtains the evaluation value using a standard by a front face degree of a main face of the subject in selecting a first representative frame, and obtains the evaluation value using a standard by a matching degree with the predetermined composition in selecting a second representative frame.
