Video playback apparatus and video playback method

A video playback method of a video playback apparatus which includes a video storage unit configured to store a compressed video signal and a decoding unit configured to perform a decoding process for the compressed video signal read out from the video storage unit, and displays, on a display unit, the video signal decoded by the decoding unit, comprising:

• a first calculation step of calculating an average color in a first frame included in the video signal decoded by the decoding unit;
• a second calculation step of calculating an average color in a second frame to be detected upon a lapse of a predetermined time after the first frame included in the video signal decoded by the decoding unit;
• a third calculation step of calculating a difference between the average color in the first frame and the average color in the second frame which are calculated in the first calculation step and the second calculation step;
• a determination step of determining whether the difference calculated in the third calculation step is larger than a predetermined threshold value;
• and
• a playback control step of controlling to play back the video signal stored in the video storage unit, in accordance with information on the second frame when the difference is determined to be larger than the threshold value in the determination step.
