摘要： An image input unit inputs an image including a user's face area to specify the user's gaze or face direction. A pattern generation unit generates an input pattern that can be compared with each dictionary pattern from the image. A dictionary unit previously stores a plurality of dictionary patterns each of which differently corresponds to the user's gaze or face direction. A pattern comparison unit respectively calculates a similarity degree between the input pattern and each of the dictionary patterns by comparing the input pattern with each of the dictionary patterns. A gaze detection unit detects the user's gaze or face direction based on the similarity degree.

摘要： An image processing apparatus. A camera inputs an image of a face of a person to be recognized. A recognition area detection section generates a difference image between the input image and a predetermined pattern, and detects a recognition area whose value is above a threshold from the input image. An input data generation section converts the recognition area to a predetermined input data. A similarity calculation section calculates a similarity by comparing the predetermined input data with a predetermined dictionary data. A view position of the camera is located lower than a position of the face of the person. A direction of the optical axis of the camera represents an angle of elevation from a horizontal direction.

摘要： An image pattern of an object is inputted. An input subspace calculation section calculates an input subspace from the image pattern. A dictionary subspace calculation section calculates a dictionary subspace from a learning pattern of each object. A constraint subspace calculation means calculates a constraint subspace from a plurality of input subspaces previously calculated according to constraints to suppress unnecessary patterns. A projection section projects the input subspace and the dictionary subspace onto the constraint subspace. A recognition section recognizes the object by comparing the projected input subspace with the projected dictionary subspace.

摘要： A security apparatus. A service is supplied to a user while maintaining the security of the service. A person discrimination section discriminates the user to be supplied the service. A user situation decision section decides whether the user is under a situation to use the service. An infringement situation decision section detects whether a non-user intrudes into a use area of the service in order to decide whether the security of the service is infringed. A service control section supplies the service to the user in case the person discrimination section discriminates the user, and controls a supply of the service if the use situation decision section decides the user is not under the situation to use the service or the infringement situation decision section decides that the security of the service is infringed.

摘要： In the multi-modal interface apparatus of the present invention, a gaze object detection section always detects a user's gaze object. The user inputs at least one medium of sound information, character information, image information and operation information through a media input section. In order to effectively input and output information between the user and the apparatus, a personified image presentation section presents a personified image to the user based on the user's gaze object. A control section controls a reception of the inputted media from the media input section based on the user's gaze object.
