     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     In the following, a description is given of embodiments of the present invention with reference to the accompanying drawings. Note that duplicated descriptions may be omitted by assigning identical reference numerals to those components having substantially the same functional configurations in the specification and the drawings of the present application. 
     First Embodiment 
     Overall Configuration of Apparatus Management System 
     Initially, a description is given of an overall configuration of an apparatus management system according to embodiments.  FIG. 1  is a diagram illustrating an overall configuration of an apparatus management system  100 . 
     As illustrated in  FIG. 1 , the apparatus management system  100  includes an apparatus management device  110 , a teleconferencing system  120 , air-conditioning apparatuses  130 , and lighting apparatuses  140 , which are mutually connected via a network  150 . Note that it is assumed that the teleconferencing system  120 , the air-conditioning apparatuses  130 , and the lighting apparatuses  140  are installed in a predetermined control area of which the employees&#39; work environment (e.g., a predetermined workspace such as conference room within an office) is controlled. 
     The apparatus management device  110  is configured to receive an image captured by the teleconferencing system  120  via the network  150  and process the captured image. Further, the apparatus management device  110  resides in the same control area as the teleconferencing system  120  and is configured to transmit control information in accordance with a processed result of the captured image to the air-conditioning apparatuses  130  and the lighting apparatuses  140  that control the employees&#39; work environment of the control area. 
     The teleconferencing system  120  includes an imaging part configured to image the employees (users) in the control area where the teleconferencing system  120  is installed, and to transmit the captured image to the apparatus management device  110 . Note that the apparatus management system  100  may have any imaging part installed in the control area and having a function capable of performing communications and capable of imaging the employees in the control area. Such an imaging part is not limited to the teleconferencing system  120 . 
     Note that when the control area is a conference room, a teleconferencing system may have already been installed in the conference room. Thus, it is not necessary to install an additional imaging part to connect the additional imaging part to the network  150  when using the existing teleconferencing system for constructing the apparatus management system  100 . That is, it may be advantageous to use the existing teleconferencing system to construct the apparatus management system  100  because an initial cost may be reduced. 
     Each of the air-conditioning apparatuses  130  is configured to control a temperature of the control area and to operate based on the control information transmitted by the apparatus management device  110 . Note that the number of air-conditioning apparatuses  130  is not limited to one in one control area, and may be two or more in the control area. 
     Each of the lighting apparatuses  140  is configured to control a lighting level of the control area and to operate based on the control information transmitted by the apparatus management device  110 . Note that the number of lighting apparatuses  140  is not limited to one in one control area, and may be two or more in the control area. 
     Configuration of Apparatus Management Device 
     Next, a description is given of a hardware configuration of the apparatus management device  110 .  FIG. 2  is a diagram illustrating a hardware configuration of the apparatus management device  110 . 
     As illustrated in  FIG. 2 , the apparatus management device  110  includes a central processing unit (CPU)  201 , a read-only memory (ROM)  202 , a random access memory (RAM)  203 , and storage device  204 . The apparatus management device  110  further includes a communications part  206 . Note that the above components of the apparatus management device  110  are mutually connected via a bus  207 . 
     The CPU  201  is a computer configured to execute a program stored in the storage device to function as an apparatus manager  210 . When the CPU  201  executes the program functioning as the apparatus manager  210 , the apparatus management device  110  receives the captured image from the teleconferencing system  120  installed in a specified control area. Further, the apparatus management device  110  processes the received image and transmits control information in accordance with the processed result of the receive image to the air-conditioning apparatuses  130  and the lighting apparatuses  140 . 
     The ROM  202  is a non-volatile memory. The ROM  202  is configured to store various types of programs, data, and the like that are necessary for the CPU  201  to execute a program to cause the CPU  201  to function as the apparatus manager  210 . Specifically, the ROM  202  is configured to store startup programs such as a basic input/output system (BIOS) and an extensible firmware interface (EFI). 
     The RAM  203  is a main storage device such as a dynamic random access memory (DRAM) or a static random access memory (SRAM). The RAM  203  is configured to serve as a work area in which a program functioning as the apparatus manager  210  is deployed when the program is executed by the CPU  201 . 
     The storage device  204  is configured to store (maintain) the program functioning as the apparatus manager  210 , employees&#39; information  220 , and layout information  230 . 
     The apparatus manager  210  includes a facial recognition part  211  configured to perform a facial recognition process, an environment manager  212  configured to perform an environmental management process, and an apparatus controller  213  configured to perform an apparatus control process. Note that a detailed description is given later of the facial recognition process performed by the facial recognition part  211 , the environmental management process performed by the environment manager  212 , and the apparatus control process performed by the apparatus controller  213 . 
     The employees&#39; information  220  is a database to manage all the employees in the office.  FIG. 3  is a diagram illustrating one example of the employees&#39; information  220 . As illustrated in  FIG. 3 , the employees&#39; information  220  registers an identification number  300  of each employee in association with a facial image  301 , attribute information  302 , an appropriate temperature  303 , appropriate temperature weighting information  304 , an appropriate lighting level  305 , and appropriate lighting level weighting information  306 . 
     The attribute information  302  includes a name, a department, a post, an age, and attribute information (together with attribute information such as “color vision deficiency”) of each employee. The appropriate temperature  303  registers the temperature at which each employee feels comfortable. The appropriate temperature weighting information  304  registers one of five levels of appropriate temperature weighting information selected by each employee. Specifically, a level 5 indicates a highest level (most comfortable) and a level 1 indicates a lowest level (most uncomfortable). The appropriate temperature weighting information  304  is configured to prioritize the highest level. 
     The appropriate lighting level  305  registers the lighting level at which each employee feels comfortable. The appropriate lighting level weighting information  306  registers one of five levels of appropriate lighting level weighting information selected by each employee. Specifically, a level 5 indicates a highest level (most comfortable) and a level 1 indicates a lowest level (most uncomfortable). The appropriate lighting level weighting information  306  is configured to prioritize the highest level. Note that the employee with the identification number “4” has color vision deficiency and his or her appropriate lighting level to acquire clear vision is predetermined. Hence, his or her appropriate lighting level weighting information  306  is predetermined at the level “5”. 
     The employees&#39; information  220  is used when the apparatus manager  210  specifies the employees in the control area based on the captured image received from the teleconferencing system  120 . Further, the employees&#39; information  220  is referred to as parameters (i.e., appropriate temperature and appropriate lighting level) of a work environment desired by each of the employees in the control area when the apparatus manager  210  calculates control information (i.e., lighting level setting value and temperature setting value) for controlling the air-conditioning apparatuses  130  and the lighting apparatuses  140 . That is, the employees&#39; information  220  is used as a database indicating a relationship between the employees and parameters of the work environment desired by the employees. 
     The layout information  230  indicates a layout of the control area.  FIG. 4  is a diagram illustrating a layout of a conference room as an example of the control area. As illustrated in  FIG. 4 , the layout information  230  includes apparatus layout information  231  illustrating a layout of the teleconferencing system  120 , a table, chairs, and the like installed in the control area (e.g., a conference room). Further, the layout information  230  includes air-conditioning layout information  232  illustrating a layout of the air-conditioning apparatuses  130  and lighting layout information  233  illustrating a layout of the lighting apparatuses  140 . 
     The layout information  230  is used when the apparatus manager  210  specifies locations of the employees in the control area. Further, the layout information  230  is used when the apparatus manager  210  calculates temperature setting values of the air-conditioning apparatuses  130  and lighting level setting values of the lighting apparatuses  140 . 
     The following description is given by referring back to  FIG. 2 . The input-output part  205  is configured to input various instructions into the apparatus management device  110  or display an internal status of the apparatus management device  110 . 
     The communications part  206  is configured to receive the captured image transmitted by the teleconferencing system  120  via the network  150 . Further, the communications part  206  is configured to transmit via the network  150  the control information (temperature setting values and lighting level setting values) calculated by processing the received captured image. 
     Apparatus Management Process Performed by Apparatus Management Device 
     Next, a description is given of an apparatus management process performed by the apparatus management device  110 .  FIG. 5  is a flowchart illustrating the apparatus management process performed by the apparatus management device  110 . In the apparatus management device  110 , when the program functioning as the apparatus manager  210  is executed, steps of the flowchart illustrated in  FIG. 5  are performed. 
     In step S 501 , the input-output part  205  receives specification of a control area. There are plural control areas within the office, and a specified one of the control areas that is subject to an apparatus management process is received in step S 501 . 
     In step S 502 , the layout information  230  of the specified control area is read. Further, in step S 503 , whether there is any apparatus to be controlled in the specified control area is determined based on the read layout information  230 . 
     In step S 503 , when it is determined that there is no apparatus to be controlled in the specified control area (“NO”), the apparatus management process is terminated. On the other hand, in step S 503 , when it is determined that there is an apparatus to be controlled in the specified control area (“YES”), step S 504  is processed. 
     Note that the air-conditioning apparatuses  130  and the lighting apparatuses  140  are each registered as an “apparatus to be controlled” in the apparatus layout information  231  and the air-conditioning layout information  232  included in the layout information  230 . Hence, it is determined that there are apparatuses to be controlled in the control area in step S 503 . 
     In step S 504 , control sections of the specified control area are identified based on the layout information  230  read in step S 502 . Specifically, air-conditioning control sections of the specified control area are identified based on the air-conditioning layout information  232  included in the layout information  230 . Further, lighting level control sections of the specified control area are identified based on the lighting layout information  233  included in the layout information  233 . 
       FIG. 6A  is a diagram illustrating air-conditioning control sections identified in step S 504 . When there are two air-conditioning apparatuses  130 , the conference room serving as an example of the control area is divided into two air-conditioning control sections. 
       FIG. 6B  is a diagram illustrating lighting apparatus control sections identified in step S 504 . When the lighting apparatuses  140  are installed in  16  places (positions), the conference room serving as the example of the control area is divided into  16  lighting level control sections. 
     The following description is given by referring back to  FIG. 5 . In step S 505 , the employees&#39; information  220  of the specified control area is read. Further, in step S 506 , the facial recognition part  211  of the apparatus manager  210  acquires a captured image from the teleconferencing system  120  installed in the specified control area and performs a facial recognition process based on the acquired image and the employees&#39; information  220 . Accordingly, the employees in the specified control area are specified. Further, respective locations (positions) of the specified employees in the control area are specified. 
     In step S 507 , an environmental management process is performed. Specifically, the environment manager  212  of the apparatus manager  210  extracts from the employees&#39; information an appropriate temperature and an appropriate lighting level of an employee specified as one in the specified control area. Further, a target temperature and a target lighting level of the specified control area are determined based on the extracted appropriate temperature and appropriate lighting level. 
     In step S 508 , an apparatus control process is performed. Specifically, the apparatus controller  213  calculates a temperature setting value of the air-conditioning apparatus  130 , and a lighting level setting value of the lighting apparatus  140  installed in the specified control area in order to implement the target temperature and the target lighting level determined in step S 507 . Note that when there are two or more air-conditioning apparatuses  130  and two or more lighting apparatuses  140  in the specified control area, the apparatus controller  213  calculates respective temperature setting values of the air-conditioning apparatuses  130 , and respective lighting level setting values of the lighting apparatuses  140 . 
     Further, the apparatus controller  213  transmits the calculated temperature setting values and the calculated lighting level setting values as the control information to the air-conditioning apparatuses  130  and the lighting apparatuses  140 , respectively. 
     In step S 509 , it is determined whether an instruction (a termination instruction) to terminate the apparatus management process in the specified control area has been received. In step S 509 , when it is determined that the instruction to terminate the apparatus management process in the specified control area has not been received (“NO”), steps S 506  to S 509  are repeatedly processed. Note that steps S 506  to S 509  are performed with a predetermined control cycle (e.g., cycle per second). 
     On the other hand, when it is determined that the instruction to terminate the apparatus management process in the specified control area has been received in step S 509  (“YES”), step S 510  is processed. 
     The instruction to terminate the apparatus management process in the specified control area may, for example, be input into the apparatus management device  110  by being accessed by the employee via his or her predetermined terminal. However, the instruction to terminate the apparatus management process is not necessarily input into the apparatus management device  110  by being accessed by the employee via his or her predetermined terminal, and may be directly input by the employee via the input-output part  205  of the apparatus management device  110 . 
     Alternatively, a utilization time for the specified control area is registered in advance, and when the apparatus management device  110  determines that the utilization time has reached the end of the utilization time, the apparatus management device  110  may be configured to determine that the termination instruction has been received. 
     Further, the apparatus management device  110  may alternatively be configured to determine that the termination instruction has been received when the power of the teleconferencing system  120  connected to the apparatus management device  110  via the network is switched off, or the transmission of the captured image is stopped. 
     Moreover, the apparatus management device  110  may alternatively be configured to determine that the termination instruction has been received when the apparatus management device  110  has detected that the power of the air-conditioning apparatus  130  or the lighting apparatus  140  installed in the specified control area is switched off. 
     In step S 510 , a termination process is performed. In step S 509 , when the employee inputs the termination instruction, the apparatus management device  110  transmits respective default values to the air-conditioning apparatus  130  and the lighting apparatus  140  as the control information. As a result, the air-conditioning apparatus  130  and the lighting apparatus  140  installed in the specified control area restore initial statuses before the apparatus management process has started. 
     Note that the termination process is not limited to that described above. The termination process may, for example, be configured such that the apparatus management device  110  transmits control information to switch off the power of the teleconferencing system  130 , the power of the air-conditioning apparatus  130 , and the power of the lighting apparatus  140  as the control information. 
     Facial Recognition Process Performed by Facial Recognition Part 
     Next, a detailed description is given of a facial recognition process (step S 506 ) performed by the facial recognition part  211 .  FIG. 7  is a flowchart illustrating details of the facial recognition process (step S 506 ) performed by the facial recognition part  211 . 
     In step S 701 , the facial recognition part  211  acquires an image captured by the teleconferencing system  120  and transmitted via the network  150 .  FIG. 8  illustrates an example of an acquired captured image  800 . The captured image  800  is a scene of six employees in a conference room that is an example of the control area. 
     In step S 702 , facial areas of the six employees are extracted from the acquired captured image. In the captured image  800  of  FIG. 8 , rectangular areas  801  to  806  indicate the extracted facial areas. Note that a technique to extract facial areas from the captured image  800  is well known in the art, a detailed description the technique is omitted from the specification. 
     In S 703 , a facial recognition process is performed on each of the facial areas extracted in step S 702  based on the employees&#39; information  220 . In this step, the similarity between the amount of a characteristic extracted from an image of the facial area (a facial area image) indicated by the rectangular area  801  and the amount of a characteristic extracted from the facial image registered in the employees&#39; information  220  is calculated. Then, the identification number having a facial image associated with it and the facial image having the highest similarity being a predetermined threshold or above is specified. 
     In step S 704 , whether the facial recognition process is successful is determined by determining whether the identification number is specified in association with the rectangular area  801 . For example, when there is no facial image having the similarity being the predetermined threshold or above among the facial images registered in the employees&#39; information  220 , the facial recognition process is determined to be a failure, and step S 703  is processed (back to step S 703 ). 
     On the other hand, when the identification number is specified in association with the rectangular area  801  (“YES”), the facial recognition process is determined to be successful, and step S 705  is processed. In step S 705 , the specified identification number is extracted from the employees&#39; information  220 . 
     In step S 706 , it is determined whether the facial recognition process is performed on all the rectangular areas extracted in step S 702 . In step S 706 , when it is determined that there remain rectangular areas on which the facial recognition process has not been performed (“NO”), step S 703  is processed to perform the facial recognition process on a subsequent one of the remaining rectangular areas. In this step, the similarity between the amount of a characteristic extracted from an image of the facial area indicated by the rectangular area  802  and the amount of a characteristic extracted from the facial image registered in the employees&#39; information  220  is calculated. Then, the identification number having a facial image with it, and the facial image having the highest similarity being a predetermined threshold or above is specified. 
     Subsequently, the facial recognition process is sequentially processed on the remaining rectangular areas  803  to  806 , and when it is determined that the facial recognition process is performed on all the rectangular areas (“YES”), step S 707  is processed. 
     In step S 707 , locational information is calculated based on respective locations of the rectangular areas  801  to  806  and the layout information  230  (i.e., the apparatus layout information  231 ). The location information indicates respective positions of the employees within the control area. 
       FIG. 9  is a diagram illustrating the respective positions of the employees in the control area that are mapped on the apparatus layout information  231  based on the locational information calculated in step S 707 . The example of  FIG. 9  illustrates a case where the facial recognition process is successful with respect to all the rectangular areas  801  to  806 , and the identification numbers associated with the rectangular areas  801  to  806  are specified. In the apparatus management device  110 , the respective positions of the employees in the control area may be specified by executing the facial recognition process (step S 506 ). 
     Environmental Management Process Performed by Environment Manager 
     Next, a detailed description is given of an environmental management process (step S 507 ) performed by the environment manager  212 .  FIG. 10  is a flowchart illustrating details of the environmental management process (step S 507 ) performed by the environment manager  212 . 
     In step S 1001 , the identification numbers and the locational information of the employees in the control area are acquired. In step S 1002 , it is determined whether the employees in the control area have registered their appropriate temperatures and appropriate lighting levels in the employees&#39; information  220  (or whether the employees reside in the control section of the control area in the first place). In step S 1002 , when it is determined that any one of the employees in the control area has not registered his or her appropriate temperature and appropriate lighting level of the employees&#39; information  220  (“NO”) (or it is determined that there is no employee in the control section), step S 1003  is processed. 
     In step S 1003 , a target temperature of each of the air-conditioning control sections within the control area is determined to be a default value. Likewise, a target lighting level of each of the lighting control sections within the control area is determined to be a default value. 
     On the other hand, when it is determined that any one of the employees within the control area has registered his or her appropriate temperature and appropriate lighting level of the employees&#39; information  220  (“YES”), step S 1004  is processed. 
     In step S 1004 , it is determined whether weighting information is registered in association with the registered appropriate temperature or the registered appropriate lighting level. In step S 1004 , when it is determined that the weighting information has been registered in association with the registered appropriate temperature or the registered appropriate lighting level (“YES”), step S 1005  is processed. 
     In step S 1005 , the target temperature or the target lighting level of the control section in which the employee having registered in association with his or her registered appropriate temperature or his or her registered appropriate lighting level resides are determined based on his or her appropriate temperature or appropriate lighting level registered in the employees&#39; information  220 . 
     Specifically, when there is an employee having the weighting information registered in association with the registered appropriate temperature or the appropriate lighting level residing alone in the control section, one of his or her appropriate temperature and appropriate lighting level registered in the employees&#39; information  220  is determined to be set at a corresponding one of the target temperature and the target lighting level of the control section. Similarly, when there are an employee having the registered weighting information and an employee having no registered weighting information in the control section, one of his or her appropriate temperature and appropriate lighting level registered in the employees&#39; information  220  is determined to be set at a corresponding one of the target temperature and the target lighting level of the control section. 
     Further, when there are plural employees having their weighting information registered in association with their registered appropriate temperatures or their registered appropriate lighting levels in the same control section, a highest one of their or their appropriate temperatures and their appropriate lighting levels registered in the employees&#39; information  220  is determined to be set at a corresponding one of the target temperature and the target lighting level of the control section. 
     Further, when there are plural employees having their weighting information registered in association with their registered appropriate temperatures or registered appropriate lighting levels in the same control section, a highest one of their or their appropriate temperatures and their appropriate lighting levels registered in the employees&#39; information  220  is determined to be set at a corresponding one of the target temperature and the target lighting level of the control section. 
     In step S 1006 , a target temperature of the air-conditioning control section in which the employee having no registered weighting information resides is determined. Specifically, a mean of the appropriate temperature registered in the employees&#39; information  220  by the employee having no registered weighting information and the appropriate temperature registered in the employees&#39; information by another employee who resides in the same air-conditioning control section is calculated, and the calculated mean of the appropriate temperatures is determined to be set at the target temperature of the air-conditioning control section. 
     Similarly, a target lighting level of the lighting level control section in which the employee having no registered weighting information resides is determined. Specifically, a mean of the appropriate lighting level registered in the employees&#39; information  220  by the employee having no registered weighting information and the appropriate lighting level registered in the employees&#39; information by another employee who resides in the same lighting level control section is calculated, and the calculated mean of the appropriate temperatures is determined to be set at the target temperature of the lighting level control section. 
       FIG. 11  is a diagram illustrating respective appropriate temperatures  303 , appropriate temperature weighting information  304 , appropriate lighting levels  305 , and appropriate lighting level weighting information  306  in the employees&#39; information registered by the employees who reside in the control area. Further,  FIGS. 12A and 12B  are diagrams illustrating examples of target temperatures and target lighting levels of the control sections (air-conditioning sections 1 and 2; lighting control sections 1 to 16) determined based on the appropriate temperatures  303 , appropriate temperature weighting information  304 , appropriate lighting levels  305 , and appropriate lighting level weighting information  306  illustrated in  FIG. 11 . 
     As illustrated in  FIGS. 12A and 12B , the target temperatures and the target lighting levels of the air-conditioning sections and lighting control sections constructing the control area, which correspond to the positions of the employees, are determined based on the appropriate temperatures  303 , appropriate temperature weighting information  304 , appropriate lighting levels  305 , and appropriate lighting level weighting information  306  in the employees&#39; information registered by the employees. Further, the target temperatures and the target lighting levels of the air-conditioning sections and lighting control sections corresponding to the positions at which no employees are located determined based on respective default values of the temperature and lighting level. 
     Apparatus Control Process Performed by Apparatus Controller 
     Next, a detailed description is given of an apparatus control process (step S 508 ) performed by the apparatus controller  213 .  FIG. 13  is a flowchart illustrating details of the apparatus control process (step S 508 ) performed by the apparatus manager  213 . 
     In step S 1301 , a lighting level setting value of each of the lighting apparatuses  140  is calculated in order to implement the target lighting level of a corresponding one of the control sections determined in the environmental management process (step S 507 ). The lighting level of each of the control sections is affected by the lighting level of the lighting apparatus  140  installed in the corresponding control section and the lighting levels of its peripheral lighting apparatuses  140  installed at the periphery of the control section. Accordingly, in the apparatus controller  213 , the lighting level setting value of each of the lighting apparatuses  140  is calculated by considering the lighting levels of its peripheral lighting apparatuses  140  in order to implement the determined target lighting level of a corresponding one of the control sections. 
     In step S 1302 , a temperature setting value of each of the air-conditioning apparatuses  130  is calculated in order to implement the target temperature of a corresponding one of the control sections determined in the environmental management process (step S 507 ). The temperature of one of the control sections is affected by the temperature of the air-conditioning apparatus  130  installed in the corresponding control section and the temperature of the air-conditioning apparatus  130  installed in the adjacent control section. Accordingly, in the apparatus controller  213 , the temperature setting value of each of the air-conditioning apparatuses  130  is calculated by considering the temperature of its adjacent air-conditioning apparatus  130  in order to implement the determined target temperature of the corresponding one of the control sections. 
     In step S 1303 , the lighting level setting value calculated in step S 1301  is transmitted as the control information to the lighting apparatus  140 . In step S 1304 , the temperature setting value calculated in step S 1302  is transmitted as the control information to the air-conditioning apparatus  130 . 
     Note that each of the lighting apparatuses  140  is configured to operate based on the received control information (i.e., the lighting level setting value). Likewise, each of the lighting apparatuses  130  is configured to operate based on the received control information (i.e., the temperature setting value). 
     Outline 
     As described above, the apparatus management system  100  according to the first embodiment is: 
     configured to register a facial image of each of the employees in the office as the employees&#39; information; 
     is further configured to register an appropriate temperature and an appropriate lighting level at which each of the employees feels comfortable, and respective weighting information with respect to the appropriate temperature and the appropriate lighting level of a corresponding one of the employees at which the employee feels comfortable; 
     is configured to store apparatus layout information, air-conditioning layout information, lighting layout information as layout information of each of the control areas, and identify the air-conditioning control sections and the lighting level control sections of a corresponding one of the control area; 
     is configured to specify the employees and to calculate locational information of the specified employees based on the captured image acquired by imaging the control area by utilizing the teleconferencing system installed in each of the control area; 
     is configured to determine the target temperature of each of the air-conditioning control sections and the target lighting level of each of the lighting level control sections based on the appropriate temperature and the appropriate lighting level registered by each of the employees in the control area, respective weighting information with respect to the appropriate temperature and the appropriate lighting level, and locational information of a corresponding one of the employees; and 
     is configured to calculate the temperature setting value of each of the air-conditioning apparatus and the lighting level setting value of each of the lighting apparatuses based on the target temperature of each of the air-conditioning control sections and the target lighting level of each of the lighting level control sections, and to transmit the calculated temperature setting value and lighting level setting value as the control information to a corresponding one of the air-conditioning apparatuses and one of the apparatuses. 
     Hence, it may be possible to control a work environment such as the temperature and the lighting level of the control area by adding the preferences or attributes of each of the employees. As a result, comfortableness of each the employees may be improved. 
     Second Embodiment 
     In the apparatus management system  100  of the first embodiment, the apparatus management device  110  is configured to control the temperature setting values of the air-conditioning apparatuses  130 . However, the invention is not limited to this configuration. The apparatus management device  110  may be configured to control air direction setting values of the air-conditioning apparatuses  130  in addition to the temperature setting values. 
     Further, the first embodiment illustrates the configuration of the apparatus management system  100  where the facial recognition process has been successful with respect to all the employees in the control area. However, the invention is not limited to this configuration. The facial recognition process has not necessarily been successful with respect to all the employees in the control area in the apparatus management system  100 . In this case, the appropriate temperatures and the appropriate lighting levels for those employees on which the facial recognition process has not been successful are not extracted. Hence, respective default values are set at the target temperature and the target lighting level of the control section in which those employees reside. Note that when there is an employee on which the facial recognition process has been successful in the same control area, the appropriate temperature and the appropriate lighting level of this employee is determined to be the target temperature and the target lighting level. 
     In addition, the first embodiment describes a configuration of the apparatus management system  100  where all the employees remain in their original positions of the control area while the apparatus management process is performed. However, the invention is not limited to this configuration. For example, when the employee in the control area moves to a different position (another control section) within the same control area, the apparatus management process is performed on the image captured after the employee has moved to the different position within the same control area. Further, when the employee in the control area moves outside the control area, the apparatus management process is performed on the image captured after the employee has moved outside the control area (i.e., the captured image includes no image of this employee who has moved outside the control area). 
     Thus, the apparatus management process performed by the apparatus management device  110  may flexibly calculate the temperature setting value and the lighting level setting value of each of the control sections of accordance with the individual movements of the employees. 
     Moreover, the first embodiment describes the configuration of the apparatus management system  100  where the apparatus management process is performed on the employees in one office. However, the invention is not limited to this configuration. For example, when two or more offices are present in one floor or in one building, the apparatus management process may be configured to be performed on respective groups of the employees of two or more offices. 
     Further, the first embodiment describes the configuration of the apparatus management system  100  where an office or the like is subject to execution of the apparatus management process. However, the invention is not limited to this configuration. For example, indoor commercial facilities other than the office may be subject to execution of the apparatus management process. 
     In addition, in the apparatus management system  100  of the first embodiment, the employees&#39; information  220  is configured to register the appropriate temperature and the appropriate lighting level of each of the employees. However, the invention is not limited to this configuration. For example, when there are two or more workspaces within the office, the employees&#39; information  220  is configured to register the appropriate temperature and the appropriate lighting level of each of the workspaces. 
     Further, the first embodiment describes the configuration of the apparatus management system  100  where one control area is divided into two or more control sections based on the number of air-conditioning apparatuses and the number of lighting apparatuses to determine the respective target temperatures for the control sections divided based on the number of air-conditioning apparatuses and the respective target lighting levels for the control sections divided based on the number of lighting apparatuses. However, the invention is not limited to this configuration. For example, the target temperature and the target lighting level may be configured to be determined based on one control section regardless of the number of the air-conditioning apparatuses and the number of the lighting apparatuses. 
     Note that the apparatus management system  100  of the first embodiment describes the configuration where the apparatus management device  110  includes the apparatus manager  210 , the employees&#39; information  220 , and the layout information  230 . However, the invention is not limited to this configuration. For example, another apparatus connected to the network  150  may include the apparatus manager  210  (or a function of a part of the apparatus manager  210 ), the employees&#39; information  220 , and the layout information  230 . 
     Third Embodiment 
     In the first and the second embodiments, the apparatus manager  210  is configured to execute a sequence of processes up to transmission of the control information to air-conditioning apparatuses or lighting apparatuses. However, the invention is not limited to these configurations. For example, the apparatus manager  210  may further be configured to execute a process such as management of an apparatus control process history and the like by utilizing the control information transmitted to the air-conditioning apparatuses or lighting apparatuses. 
       FIG. 14  is a diagram illustrating another functional configuration of an apparatus manager  1410 . As illustrated in  FIG. 14 , the apparatus manager  1410  includes a control history manager  1411 , and a fee information generator  1412  in addition to the facial recognition part  211 , the environment manager  212 , and the apparatus controller  213 . 
     The control history manager  1411  is configured to manage a history of the apparatus control process performed by the apparatus controller  213 . Specifically, when the termination process is performed in step S 510  of  FIG. 5 , the control history manager  1411  stores executed contents of the apparatus control process as control history information. 
     The fee information generator  1412  generates fee usage information in a predetermined control area by utilizing the control history information managed by the control history manager  1411  and not-illustrated predetermined fee information. Further, the fee information generator  1412  outputs the generated fee usage information to a predetermined output destination via the communications part  206 . 
     Hence, the various types of processes based on the control history information may be implemented by managing the history of the apparatus control process executed by the apparatus control device  110  as the control history information. 
     The above-described first to third embodiments may be able to improve comfortableness of workspace.
