Video editing apparatus and video editing method

A video editing method used in a video editing apparatus comprising an input unit, a subject size detection unit, a subject size change amount calculation unit, a playback speed correction amount setting unit, a playback speed correction unit, and a video data concatenation unit,

• the method comprising:
• an input step, performed by the input unit, of inputting first video data and second video data in which the same subject moves and that have the same playback speed;
• a subject size detection step, performed by the subject size detection unit, of detecting a representative size of the subject in both the first video data and the second video data as a subject size;
• a subject size change amount calculation step, performed by the subject size change amount calculation unit, of calculating a proportion of the subject size in the second video data to the subject size in the first video data as a subject size change amount;
• a playback speed correction amount setting step, performed by the playback speed correction amount setting unit, of setting a correction amount for correcting a playback speed of the second video data in accordance with the subject size change amount by referring to a table in which a relationship between the subject size change amount and the correction amount for correcting the playback speed of the second video data is set in advance such that the playback speed of one of the first video data and the second video data that has a larger subject size is slower than the playback speed of the other video data;
• a playback speed correction step, performed by the playback speed correction unit, of generating third video data by correcting the playback speed of the second video data in accordance with the correction amount set in the playback speed correction amount setting step;
• and
• a video data concatenation step, performed by the video data concatenation unit, of concatenating the first video data and the third video data so as to enable continuous playback of the first video data and the third video data.
