Imaging system and program for detecting a movement of a subject and initializing imaging devices to perform subject authentication based on the movement
First Claim
1. An imaging system for imaging a subject, comprising:
- a plurality of imaging devices, provided at different positions, respectively, operable to image said subject;
a direction detection unit operable to detect a moving direction of said subject based on two or more images of said subject taken at different times by one of said plurality of imaging devices;
a selection unit operable to select one of said plurality of imaging devices, that is to capture an authentication image of said subject, based on said moving direction detected by said direction detection unit and said positions of said plurality of imaging devices;
a storage unit operable to store said authentication image captured by said selected one of said plurality of imaging devices; and
an authentication unit operable to authenticate said subject based on said authentication image stored in said storage unit;
wherein said selection unit detects a frontal direction of said subject based on said moving direction detected by said direction detection unit and selects one of said plurality of imaging devices, that is able to image a front view of said subject, based on said positions of said plurality of imaging devices,said selection unit selects said one of said plurality of imaging devices, that is to capture said authentication image of said subject, based on said detected moving direction, said detected moving direction used to calculate a position to which said subject will move to, and based on positional information related to said position of each of said plurality of imaging devices, andsaid selection unit determines which one of said plurality of imaging devices to select by detecting said frontal direction of said subject and determining which one of said plurality of imaging devices is near said calculated position to which said subject will move to based on said positional information related to said position of each of said plurality of imaging devices and is in a position to capture said front view of said subject, said selection unit initializes said one of said plurality of imaging devices to capture said authentication image of said subject.

Abstract
An imaging system is provided which can efficiently capture an authentication image of a subject by an imaging device provided around a position toward which the subject is moving. The imaging system includes; a plurality of imaging devices, provided at different positions, respectively, for capturing moving images; a direction detection unit for detecting the moving direction of the subject based on the moving image in which the subject is contained; a selection unit for selecting one of the imaging devices, that is to capture the authentication image of the subject based on the moving direction thus detected and the positions of the imaging devices; and a storage unit for storing the authentication image captured by the selected imaging device.

39. A computer program product having computer instructions, recorded on a computer readable medium, for enabling a computer executing the computer instructions to perform operations comprising:
- imaging a subject;
detecting a moving direction of said subject based on two or more images of said subject taken at different times by one of said plurality of imaging devices; selecting one of said plurality of imaging devices, that is to capture an authentication image of said subject, based on said moving direction detected by said direction detection unit and said positions of said plurality of imaging devices; storing said authentication image captured buy said selected one imaging device; and authenticating said subject based on said authentication image stored in said storage unit; wherein said selecting is a detection of a frontal direction of said subject based on said moving direction detected by said direction detection unit and selects one of said plurality of imaging devices, that is able to image a front view of said subject, based on said positions of said plurality of imaging devices, said selecting includes selecting said one of said plurality of imaging devices, that is to capture said authentication image of said subject, based on said detected moving direction, said detected moving direction used to calculate a position to which said subject will move to, and based on positional information related to said position of each of said plurality of imaging devices, and said selecting includes determining which one of said plurality of imaging devices to select by detecting said frontal direction of said subject and determining which one of said plurality of imaging devices is near said calculated position to which said subject will move to based on said positional information related to said position of each of said plurality of imaging devices and is in a position to capture said front view of said subject, and initializing said one of said plurality of imaging devices to capture said authentication image of said subject.
