Patent ID: 8385598

Claim:
An action analysis apparatus comprising: an acquiring unit that acquires moving image data including a series of frame image data obtained by imaging a human body and environmental information in a period when the moving image data is imaged; a unit that detects at least one image area in which a predetermined portion of the imaged human body is imaged in the frame image data included in the acquired moving image data and generates and stores information to identify the detected image area; a unit that (i) generates feature quantity information, (ii) generates information to identify frames of the moving image data imaged at a timing at which the feature quantity information satisfies a predetermined condition, (iii) obtains a length of continuous timings at which a length of the feature quantity information exceeds the predetermined condition based on the generated information, and (iv) stores a first frame of the moving image data and a last frame of the moving image data related to the feature quantity information over the continuous timings as well as both the generated information and the length of the continuous timings as feature time point information, wherein the feature time point information is applied to present the moving image data to a user, and the feature quantity information indicates a facial expression of the human body, and the predetermined condition is a condition that the facial expression is a wry facial expression; and a hand identification processing section that obtains a zero-order moment, a first-order moment and a second-order moment of a likelihood value, wherein the hand identification processing section moves a search area based on the obtained zero-order moment, adjusts a size of the search area based on the obtained first-order.
