Abstract

This is a system having a personal identification function to perform a registering operation not as an explicit one. The system simplifies the confirmation of an identification result thereby to improve dictionary updating conveniences. A device control apparatus is configured to include a face identification processor, a device setting unit and an interactive processor. The device control apparatus is configured to acquire personal data on the face image of a user, to identify a person matching the acquired personal data, by comparing the acquired personal data and registered personal dictionary data, to display the face image, as matching the identified person, at the registration time on the basis of the registered personal dictionary data, to receive such confirmation information from the user as to confirm whether or not the displayed person is identical to the user, and to set device environment parameters matching the confirmed person.

Claims

1. An apparatus for setting a device configuration parameter of setting a device:

an image inputting unit configured to input a face image of the user;

an extracting unit configured to extract personal feature data from the face image;

a dictionary storage configured to store personal dictionary data of one or a plurality of registered persons, the personal dictionary data including a face image and a dictionary feature data of the each registered person;

a face identification processor configured to identify a person matching the personal feature data, by comparing the personal feature data and the personal dictionary data of the each registered person;

a device configuration parameter storage configured to store a device configuration parameter of the device for the each registered person;

a display configured to display the face image of the identified person stored in the dictionary storage;

an interactive processor configured to receive, from the user, confirmation information to confirm whether or not the displayed face image is identical to the user; and

a device setting unit configured to set, to the device, the device configuration parameter of the confirmed person stored in the device configuration parameter storage;

an integration unit that is configured;

to obtain a similarity between plural ones of the personal dictionary data stored in the dictionary storage;

to call the device configuration parameters corresponding to the plural ones of personal dictionary data having the similarity higher than a threshold, from the device configuration parameter storage;

to compare similarities between the called device configuration parameters; and

to integrate said plural ones of the personal dictionary data with each other when the similarities between the called device configuration parameters are higher than a threshold.

2. An apparatus for setting a device configuration parameter of setting a device:

an image inputting unit configured to input a face image of the user;

an extracting unit configured to extract personal feature data from the face image;

a dictionary storage configured to store personal dictionary data of one or a plurality of registered persons, the personal dictionary data including a face image and a dictionary feature data of the each registered person;

a face identification processor configured to identify a person matching the personal feature data, by comparing the personal feature data and the personal dictionary data of the each registered person;

a device configuration parameter storage configured to store a device configuration parameter of the device for the each registered person;

a display configured to display the face image of the identified person stored in the dictionary storage;

an interactive processor configured to receive, from the user, confirmation information to confirm whether or not the displayed face image is identical to the user; and

a device setting unit configured to set, to the device, the device configuration parameter of the confirmed person stored in the device configuration parameter storage;

a person estimating unit configured to detect modification of the device configuration parameter by operation of the device by the user, and to estimate a person corresponding to the modified device configuration parameter from the registered person on basis of data on the device configuration parameter storage; and

wherein said display is further configured to display the face image of the estimated person, which is stored in the dictionary storage.

3. An apparatus for setting a device configuration parameter of setting a device:

an image inputting unit configured to input a face image of the user;

an extracting unit configured to extract personal feature data from the face image;

a dictionary storage configured to store personal dictionary data of one or a plurality of registered persons, the personal dictionary data including a face image and a dictionary feature data of the each registered person;

a face identification processor configured to identify a person matching the personal feature data, by comparing the personal feature data and the personal dictionary data of the each registered person;

a device configuration parameter storage configured to store a device configuration parameter of the device for the each registered person;

a display configured to display the face image of the identified person stored in the dictionary storage;

an interactive processor configured to receive, from the user, confirmation information to confirm whether or not the displayed face image is identical to the user; and

a device setting unit configured to set, to the device, the device configuration parameter of the confirmed person stored in the device configuration parameter storage;

a person estimating unit configured to detect modification of the device configuration parameter by operation of the device by the user, and to estimate a person corresponding to the modified device configuration parameter from the registered person on basis of data on the device configuration parameter storage; and

wherein the face identification processor identifies using the personal dictionary data of the estimated person.
