PROBLEM TO BE SOLVED: To make a gesture recognition apparatus correctly recognize start and end of a gesture without use of a special unit by natural manipulation of a user and low-load processing for the apparatus. SOLUTION: The gesture recognition apparatus 100 that recognizes the gesture from action of a recognition object taken in a moving image includes: a gravity center tracking unit 11 that detects a specific subject (palms etc.) having a specific feature from the moving image; a moving speed determining unit 12 that computes a moving speed per unit time of the specific subject; a moving pattern extracting unit 13 that extracts a moving pattern of the specific subject; and a start/end judgement unit 14 that discriminates movement of the specific subject as an instruction (such as an instruction to start or end gesture recognition processing) input to the geneture recognition apparatus when the moving speed and the moving pattern satisfy predetermined conditions.
