Claim One:
1. An action recognition apparatus comprising: a processor; a non-transitory computer-readable medium for storing a program, wherein the program causes the processor to function as: a moving-object detection unit for detecting a dynamic area from time-series image data input by an input unit; a moving-object identification unit for evaluating a first similarity between geometrical features extracted from the time-series image data of the dynamic area and model data pre-set for each subject person, evaluating a second similarity between a feature of an action pattern extracted from the time-series image data of the dynamic area and action-related model data peculiar to each subject person, and identifying an individual subject person corresponding to the time-series image data of the dynamic area based on a detection level which is output by weighting to both of the first and second similarities, wherein the weighting to both of the first and second similarities is applied based on both an observation position of the time-series image data and an orientation of the individual subject person, the observation position being a position from where the input unit observes the individual subject person; a state detection unit for detecting an action pattern of the identified individual subject person by the moving-object identification unit from the time-series image data; a determining unit for determining whether an action category corresponding to the detected action pattern of the identified individual subject person is stored in a recording unit, wherein the action category and the identified individual subject person are associated with device control information specific to the identified individual subject person, the associated device control information being used to control a predetermined device when the action pattern corresponding to the associated action category is performed by the associated individual subject person; a learning unit for learning an action category corresponding to the detected action pattern performed by the identified individual subject person when the determining unit determines that the action category corresponding to the detected action performed by the identified individual subject person is not stored in the recording unit; and a control unit for determining whether the identified individual subject person confirms a content of the device control information associated with the action category corresponding to the detected action pattern of the identified individual subject person when the determining unit determines that the action category corresponding to the detected action pattern of the identified individual subject person is stored in the recording unit, and for outputting the device control information as a device control signal when it is determined that the identified individual subject person confirms the content of the device control information.
