摘要:
A security system to give a user in a specific area use authority based on authentication, and to permit use of the specific area by the use authority. The security system includes an authentication unit to authenticate a user, a position detection unit to detect at least one of a position and move of a user, and a use authority control unit to monitor at least one of a position and move of a user to whom the use authority is given based on the authentication of the authentication unit by a detection output of the position detection unit, and, if a distance between users is equal to or below a predetermined value, to change the use authority which is given to each user.

A focus adjusting apparatus (100) adjusts a focus of a camera (200) imaging a moving object (12). The apparatus (100) includes a calculating unit (104) that calculates a first out-of-focus level of a portion (21) corresponding to the moving object (12) within a first region of an image (20) picked up by the camera (200), and calculates a second out-of-focus level of a portion (23) corresponding to the moving object (12) within a second region of an image(22) picked up by the camera (200); and a focus adjusting unit (106) that shifts the focus of the camera (200) in a direction in which the camera (200) is focused onto the portion (21) corresponding to the moving object (12) within the first region when the first out-of-focus level calculated by the calculating unit (104) is larger than the second out-of-focus level calculated by the calculating unit (104), and that shifts the focus of the camera (200) in a direction in which the camera (200) is focused onto the portion (23) corresponding to the moving object (12) within the second region when the second out-of-focus level is larger than the first out-of-focus level.

An apparatus for converting gray levels of an image, a method thereof, a program storage device thereof, and an infrared camera. The object of the present invention is to provide an apparatus for converting gray levels into fewer gray levels without missing a local gradation, a method thereof, a program storage device thereof, and an infrared camera to which the present invention is applied. A positive mask image (C) and a reversed mask image (C') are obtained the edge detected image (B) which is produced by emphasizing edges of an original image (A). A low frequency component (D) is obtained by performing an edge preserving smoothing operation for A masked with C, and performing a non-edge preserving smoothing operation for A masked with C'. A high frequency component (E) is obtained by calculating of (A - D). After D is compressed to D' and E is emphasized to E', an output image (F') is obtained by adding D' and E'.

A region extraction apparatus for extracting a desired region from a moving image, includes a region specifying unit for specifying contour points of a region which is to be extracted, a template creating unit (13) for creating a template of the region which is to be extracted based on the contour points of the region specified by the region specifying unit, a template matching unit (14) for matching the template created by the template creating unit and the moving image, and a template correcting unit (15) for correcting the template depending on a matching result obtained by the template matching unit.
摘要:
An authentication apparatus includes a registration unit that registers authentication information representing a check target, a first authentication unit that authenticates the check target at the entrance of the check target to a first area, a second authentication unit that authenticates the check target at the entrance of the check target to a second area after being authenticated by the first authentication unit, and a detector that detects a check target present in a detection area and expected to be authenticated by the second authentication unit. The second authentication unit retrieves, from the registration unit, registration information of the check target detected by the detector, and authenticates the check target authenticated by the first authentication unit using the registration information.
摘要:
An apparatus for extracting image data of an object in an input image data. The apparatus includes a display device having a display screen for displaying a plurality of predetermined images; a display controller for controlling the display device to display one of the predetermined images; an imaging device for taking an image of an object placed before the display screen in order to generate an input image data; a controller for controlling the imaging device to take an image of the object and the display screen when the display device displays one of the predetermined images in cooperation with the display controller; and an extractor for extracting image data of the object by comparing the input image data generated by imaging device with data of the one of the plurality of the predetermined images.
摘要:
A sensor diagnostic apparatus for diagnosing a sensor includes a moving object counter, a reference value storage, and a comparator. The moving object counter counts, in accordance with identification data acquired by a plurality of sensors in a predefined time period, a local number of moving objects moving between a sensing area of a first sensor and a sensing area of a second sensor near the first sensor. The reference value storage stores a preset reference value for the first sensor and the second sensor. The comparator compares a value derived from the local number of moving objects counted by the moving object counter with the preset reference value stored in the reference value storage to determine the first sensor to be in trouble when a difference between the value derived from the local number of moving objects and the preset reference value exceeds a predefined threshold value.
