     An embodiment of the image processing apparatus, the wearable image processing apparatus, and the method of controlling the image processing apparatus is explained in detail below with reference to the accompanying drawings. In an example explained in this embodiment, the wearable image processing apparatus is applied to a user interface used by a chef in an order system set in a restaurant or the like. 
       FIG. 1  is a diagram of an example of an order system according to this embodiment. As shown in  FIG. 1 , the order system includes a wearable image processing apparatus  1 , an order management server  30 , a printer server  32 , a transmitting and receiving device  34 , an order terminal  35 , an advertisement terminal  36 , and a fixed camera  37 . The wearable image processing apparatus  1  is a user interface that a wearer  2  as a chef wears and uses. The order management server  30  manages an order from the order terminal  35 . The printer server  32  controls a printer  31  for printing various slips (e.g., an order slip). The transmitting and receiving device  34  performs transmission and reception of data to and from the wearable image processing apparatus  1 . A store clerk such as a waiter or a waitress uses the order terminal  35  in receiving an order from a customer. The advertisement terminal  36  displays an advertisement and receives an order for an advertised item. The fixed camera  37  is fixed in a predetermined position and picks up an image of an area set in advance. The wearable image processing apparatus  1 , the order management server  30 , the printer server  32 , the transmitting and receiving device  34 , the order terminal  35 , the advertisement terminal  36 , and the fixed camera  37  are connected to one another via a network NT. The network NT is a LAN (Local Area Network), an Intranet, an Ethernet (registered trademark), or the like. 
     The transmission and reception of data between the transmitting and receiving device  34  and the wearable image processing apparatus  1  may be performed by using a radio wave, light, an infrared ray, ultrasound, or the like. In this embodiment, it is assumed that the transmission and reception of data is performed by using near radio communication (e.g., Bluetooth (registered trademark)) having a communication range of about several meters. Plural transmitting and receiving devices  34  are provided to cover all areas in a restaurant (e.g., near a checkout counter, a floor of customer tables, and a backyard). The transmitting and receiving device  34  may perform transmission and reception of data with the order terminal  35 . It is unnecessary to connect the order terminal  35  to the network NT by wire. 
     The order management server  30  manages an order for food input to the order terminal  35  by a store clerk. Specifically, the order management server  30  allocates a unique order number to order information notified from the order terminal  35 , stores the order number in a storage or the like in the order management server  30 , and registers order information. The order information includes a customer table from which an order is received, the number of customers, order items, the numbers of the order items, and the like. The order information registered in the order management server  30  is printed as an order slip by the printer  31  together with the order number. The order slip is passed to a customer as a slip used for checkout in a POS terminal  33 , for example, after foods are provided. The order management server  30  notifies the wearable image processing apparatus  1  of the registered order information and delivers various kinds of information to the order terminal  35 . 
     The POS terminal  33  includes a drawer, a key input unit, a scanner, a card reader, a display, a receipt and journal printer and the like (all of which are not shown in the figure). The POS terminal  33  performs a transaction using cash or a credit card. The POS terminal  33  is provided in, for example, a checkout counter. For example, the POS terminal  33  receives, through key input, scanner reading, or the like, an order number printed on an order slip and acquires order information corresponding to the order number from the order management server  30 . The POS terminal  33  reads out a master file, in which an identification code and a price for each of food items (menu items) are preset, from an internal ROM (Read Only Memory) or a data server (not specifically shown) and performs settlement of an order related to the acquired order information. 
     The order terminal  35  is an information terminal used by a store clerk. The order terminal  35  includes a display such as a LCD (Liquid Crystal Display) and an operation input unit such as a touch panel for receiving an operation input. The order terminal  35  receives an order from a customer input through the operation input unit and displays, on a display, information delivered from the order management server  30 . 
     The advertisement terminal  36  is information terminal set on a customer table, the outdoors, or the like and displays an advertisement and receives an order for an advertised item. The advertisement terminal  36  includes a display such as a LCD (Liquid Crystal Display) and an operation input unit such as a touch panel for receiving an operation input. For example, the advertisement terminal  36  displays a video of cooking as an advertisement and receives an order for a food item being cooked (details are explained later). 
     The wearable image processing apparatus  1  is an information terminal that the wearer  2  (a chef) wears and uses. The wearable image processing apparatus  1  includes a head mount display  10 , a digital camera  11  as an imaging device, an interface box  12 , and a microphone  15 . As shown in  FIG. 2 , the head mount display  10  includes a frame body  13  for holding a light transmissive member  16  including a monitor display unit  17  and a mounting arm  14  of a headphone type for arranging the frame body  13  in front of the left eye of the wearer  2 . Specifically, the head mount display  10  can be mounted on a head  2   a  of the wearer  2  by the mounting arm  14 . In a mounted state, the frame body  13  is arranged in front of the left eye of the wearer  2 . 
     The frame body  13  is formed in a shape of a size adjusted to the left eye of the wearer  2 . The digital camera  11  is provided in an upper part on the outside of a frame of the frame body  13  via an imaging direction variable mechanism  18 . A camera for line-of-sight recognition  19  for picking up an image of the pupil of the wearer  2  and detecting a line of sight  2   b  (a line of sight position) is provided on the outside of the frame of the frame body  13 . The microphone  15  for collecting sound of the wearer  2  and around the wearer  2  is provided below the frame body  13 . The light transmissive member  16  of a tabular shape formed to be adjusted to, for example, a shape of the frame of the frame body  13  is held in the frame. Even when the head mount display  10  is mounted on the head  2   a  of the wearer  2 , the light transmissive member  16  allows the eyes of the wearer  2  to observe an ambient environment. The light transmissive member  16  may be, for example, colorless and transparent or have a color determined in advance. 
     The monitor display unit  17  is formed in a part in the light transmissive member  16 . The monitor display unit  17  monitor-displays, on a real time basis, for example, image data of a moving image acquired by imaging by the digital camera  11  and various kinds of information. Therefore, monitor display on the left eye of the wearer  2  can be performed in a state in which the head mount display  10  is mounted. The monitor display unit  17  performs monitor display in a light transmissive state. Therefore, the monitor display unit  17  allows the wearer  2  to observe an ambient environment even in a state in which the monitor display is performed on a real time basis. For example, with the wearable image processing apparatus  1 , even when the chef is cooking foods, the chef can check the monitor display while cooking the foods. 
     In the example explained in this embodiment, the frame body  13  is arranged in front of the left eye of the wearer  2  and the monitor display on the left eye of the wearer  2  is performed. However, the monitor display for the wearer  2  may be performed on the right eye or both the eyes. For example, it is possible to perform the monitor display on the right eye of the wearer  2  by arranging the frame body  13  in front of the right eye of the wearer  2 . 
     The digital camera  11  as a first camera performs imaging operation and outputs image data of a moving image. The digital camera  11  is attached on the frame body  13  of the head mount display  10  in a state in which an imaging range is set such that a focus is adjusted to the direction of the line of sight  2   b  of the wearer  2  through the light transmissive member  16 . For example, the imaging direction variable mechanism  18  supports the digital camera  11  to be capable of swinging. The imaging direction variable mechanism  18  sets an imaging direction of the digital camera  11  such that the focus is adjusted to an arbitrary direction, i.e., the direction of the line of sight  2   b  of the wearer  2  as explained above. Therefore, when the chef wearing the wearable image processing apparatus  1  is cooking foods, an image of an area where the cooking is performed can be picked up. 
     The interface box  12  performs transmission and reception of data to and from the transmitting and receiving device  34  and performs various kinds of processing related to the head mount display  10 . Specifically, the interface box  12  includes a control unit  121 , a sound processing unit  122 , a transmitting and receiving unit  123 , an information display unit  124 , and an image processing unit  125 . The interface box  12  is a box that the wearer  2  can carry. The control unit  121  is a computer including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM and the like. The control unit  121  controls the operation of the wearable image processing apparatus  1 . A program, various kinds of setting information referred to when the program is executed, and the like are stored in the ROM in advance. The CPU expands the program stored in the ROM on a work area of the RAM and sequentially executes the program to centrally control the operation of the wearable image processing apparatus  1 . Functions of the units such as the image processing unit  125 , the information display unit  124 , the transmitting and receiving unit  123 , and the sound processing unit  122  in the interface box  12  may be realized by the control unit  121  executing the program stored in the ROM in advance. 
     The sound processing unit  122  performs processing such as recognition of sound input from the microphone  15 . Specifically, the sound processing unit  122  collates sound data included in dictionary data set in advance and sound data from the microphone  15  and recognizes a predetermined sound command. The sound processing unit  122  notifies the control unit  121  of the recognized sound command. The control unit  121  performs processing corresponding to the notified sound command. Consequently, the wearable image processing apparatus  1  can be operated by a sound command uttered by the wearer  2 . The operation of the wearable image processing apparatus  1  by the sound command is hereinafter referred to as sound operation. The wearable image processing apparatus  1  receives sound operation by the wearer  2 . Therefore, labor and time of manual input by the wearer  2  can be omitted. In particular, this sound operation is effective when the wearer  2  is cooking foods. 
     The information display unit  124  displays, on the monitor display unit  17  of the head mount display  10 , image data input from the control unit  121  or the like. The information display unit  124  displays, under the control by the control unit  121 , various images of an information window, an icon, and the like at a predetermined coordinate of the monitor display unit  17 . 
     The image processing unit  125  performs image processing for image data acquired by the imaging by the digital camera  11  and analyzes image data picked up by the camera for line-of-sight recognition  19  to detect the line of sight  2   b  of the wearer  2 . Specifically, the image processing unit  125  detects the pupil of the wearer  2  from the image data picked up by the camera for line-of-sight recognition  19 . Subsequently, the image processing unit  125  detects the line of sight  2   b  according to the position of the detected pupil. A detection result of the line of sight  2   b  is output to the information display unit  124 . The information display unit  124  displays an order display window at a coordinate of the monitor display unit  17  corresponding to the detection result of the line of sight  2   b  output from the image processing unit  125 . 
     The input operation in the wearable image processing apparatus  1  may be performed under the control by the control unit  121  on the basis of an image of the camera for line-of-sight recognition  19  according to the line of sight  2   b  detected by the image processing unit  125 . Specifically, the input operation in the wearable image processing apparatus  1  is performed by detecting the line of sight  2   b  of the wearer  2  looking at an icon image for operation input displayed on the monitor display unit  17  by the information display unit  124 . For example, when an icon image displayed at a predetermined coordinate of the monitor display unit  17  and an order display window by a detection result of the line of sight  2   b  overlap, input operation corresponding to the icon image is received. The input operation in the wearable image processing apparatus  1  corresponding to the line of sight  2   b  is hereinafter referred to as line-of-sight operation. The wearable image processing apparatus  1  receives the line-of-sight operation by the wearer  2 . Therefore, labor and time of manual input by the wearer  2  can be omitted. In particular, this line-of-sight operation is effective when the wearer  2  is cooking foods. 
     The fixed camera  37  as a second camera is a digital camera fixed in the kitchen. The fixed camera  37  picks up an image of an area where the chef actually performs cooking in the kitchen (hereinafter referred to as cooking area).  FIG. 3  is a diagram of an example of the kitchen. As shown in  FIG. 3 , the fixed camera  37  is fixedly provided on a wall or the like of the kitchen and picks up images of a gas range, a kitchen table, and the like in the cooking area while panning a focus. Therefore, an imaging range of the fixed camera  37  is the entire cooking area and a video picked up by the fixed camera  37  is a video of the entire cooking area. The video picked up by the fixed camera  37  is delivered to the advertisement terminal  36  according to an instruction of the wearable image processing apparatus  1 . 
     Identification markers M 1  to M 4  are markers for identifying the cooking area and arranged in advance to correspond to the cooking area. For example, the identification marker M 1  is arranged at the upper left corner of the cooking area. The identification marker M 2  is arranged at the upper right corner of the cooking area. The identification marker M 3  is arranged at the lower right corner of the cooking area. The identification marker M 4  is arranged at the lower left corner of the cooking area. The identification markers M 1  to M 4  are painted in different patterns or colors to be identifiable from one another. Therefore, in the wearable image processing apparatus  1  that is not fixed to perform imaging, it is possible to determine, by detecting the identification markers M 1  to M 4  from a picked-up video, whether the video is a video of the cooking area (details are explained later). 
     The operation of the order system according to this embodiment is explained below.  FIG. 4  is a ladder chart of an example of the operation of the order system according to this embodiment. 
     As shown in  FIG. 4 , the order terminal  35  receives an order input of a customer table from which an order is received, the number of customers, order items, the numbers of the order items, and the like (Act  1 ). Subsequently, the order terminal  35  notifies the order management server  30  of the received order as order information (Act  2 ). 
     The order management server  30  registers the order information notified from the order terminal  35  (Act  3 ). Subsequently, the order management server  30  notifies the wearable image processing apparatus  1  of the registered order information and an order number of the order information (Act  4 ). The wearable image processing apparatus  1  displays the order information notified from the order management server  30  on the monitor display unit  17  (Act  5 ). 
       FIG. 5  is a diagram of a display example of the monitor display unit  17 . More specifically,  FIG. 5  is a diagram of a display example of the order information notified from the order management server  30 . In  FIG. 5 , a line-of-sight marker G 1  is a marker displayed on the monitor display unit  17  according to a detection result of the line of sight  2   b . An order display window G 2  is a display window for displaying the notified order information. A delivery icon G 3  is an icon for receiving a delivery instruction for a video of the cooking area according to the line-of-sight operation. 
     As shown in  FIG. 5 , in Act  5 , the order information notified from the order management server  30  is displayed in the order display window G 2 . Specifically, order icons G 21  to G 23  corresponding to order items included in the order information are displayed in the order display window G 2 . Consequently, the chef can start cooking of the order items included in the order information. 
     Subsequently, the wearable image processing apparatus  1  receives delivery setting for the video of the cooking area according to the sound operation or the video operation (Act  6 ). Specifically, in the case of the sound operation, the wearable image processing apparatus  1  performs the delivery setting for the video according to a sound command for instructing delivery of the video such as “deliver a video”. In the case of the line-of-sight operation, the wearable image processing apparatus  1  performs the delivery setting for the video when the wearable image processing apparatus  1  detects that the line-of-sight marker G 1  overlaps the delivery icon G 3  for a predetermined time. 
     In the delivery setting in Act  6 , the wearable image processing apparatus  1  may set, according to the sound operation or the video operation, to which of the order items a video to be delivered corresponds.  FIG. 6  is a diagram of a display example of the monitor display unit  17 . More specifically,  FIG. 6  is a diagram of an example of setting for order items. As shown in  FIG. 6 , in the case of the line-of-sight operation, the wearable image processing apparatus  1  performs the setting for order items by superimposing the line-of-sight marker G 1  on an order icon. In the example shown in the figure, the wearable image processing apparatus  1  superimposes the line-of-sight marker G 1  on the order icon G 21  to set “kara-age” as an order item of a video to be delivered. Subsequently, the wearable image processing apparatus  1  delivers a video of “kara-age” set by the line-of-sight operation using the delivery icon G 3 . In the case of the sound operation, the wearable image processing apparatus  1  sets, according to a sound input of “order  1 ” or “kara-age”, “kara-age” corresponding to content of the sound as an order item of the video to delivered. Subsequently, the wearable image processing apparatus  1  delivers the video of “kara-age” according to a sound input such as “start delivery”. 
     Subsequently, the wearable image processing apparatus  1  delivers, together with information indicating the set order item, a video of the cooking area picked up by the digital camera  11  or the fixed camera  37  according to the delivery setting in Act  6 , to the advertisement terminal  36  (Act  7 ). For example, in Act  6  and Act  7 , after the display of the order information, the wearable image processing apparatus  1  receives selection of a cooking start item as the delivery setting according to the sound operation or the video operation, adds the order information of the cooking start item to the video of the cooking area, and delivers the order information. The order information of the cooking start item is added and delivered in order to show which food item is cooked in the video of the cooking area to be delivered. The advertisement terminal  36  displays, on the display, the video of the cooking area delivered from the wearable image processing apparatus  1  together with the delivered order information (Act  8 ). Therefore, in Act  8 , the food item cooked in the video is displayed as a recommended lunch of the day or the like together with the video of the cooking area. Subsequently, the advertisement terminal  36  receives an order for the order item delivered together with the video (Act  9 ). The advertisement terminal  36  notifies, as order information, the order management server  30  of the order received in Act  9  (Act  10 ). The order management server  30  registers, as new order, the order information notified from the advertisement terminal  36  (Act  11 ). 
       FIG. 7  is a diagram of a display example of a display  36 L in the advertisement terminal  36 . As shown in  FIG. 7 , in Act  8 , a video of the cooking area is displayed in a cooking video display area L 1  on the display  36 L of the advertisement terminal  36 . In this way, a video of cooking is displayed on the advertisement terminal  36  set on a customer table or the outdoors. This makes it possible to urge a customer to make a new order. On the display  36 L of the advertisement terminal  36 , an order icon L 2  for receiving, in the operation input unit such as a touch panel, an order for the order item delivered together with the video of the cooking area. Therefore, according to Act  9  to Act  11 , it is possible to receive anew an order concerning an order item being cooked. 
     Details of processing performed by the wearable image processing apparatus  1  under the control by the control unit  121  are explained below with reference to  FIG. 8 .  FIG. 8  is a flowchart for explaining the processing by the wearable image processing apparatus  1  according to this embodiment. 
     As shown in  FIG. 8 , when the processing is started, the control unit  121  displays, on the monitor display unit  17 , an order item included in order information notified from the order management server  30  (Act  101 ). Subsequently, the control unit  121  determines, according to the sound operation or the line-of-sight operation, whether delivery of a video of the cooking area is instructed (Act  102 ). If the delivery is not instructed (No in Act  102 ), the control unit  121  advances the processing to Act  108 . 
     When the delivery is instructed (Yes in Act  102 ), the control unit  121  acquires a video picked up by the digital camera  11  (Act  103 ). Subsequently, the control unit  121  determines, whether the acquired video is a video of a predetermined area, i.e., a video of the cooking area (Act  104 ). As explained above, the control unit  121  performs the determination in Act  104  by detecting the identification markers M 1  to M 4  from the acquired video. Specifically, if the identification marker M 1  arranged at the upper left corner of the cooking area is detected on the upper left of the acquired video, the control unit  121  determines that the acquired video is a video of the cooking area. Similarly, in the acquired image, if the identification marker M 2  is detected on the upper right, if the identification marker M 3  is detected on the lower right, or if the identification marker M 4  is detected at the left corner, the control unit  121  determines that the acquired video is a video of the cooking area. Conversely, in the acquired video, if the identification markers M 1  to M 4  are detected in positions other than those explained above or if the identification markers M 1  to M 4  are not detected, the control unit  121  determines that an image of the cooking area surrounded by the identification markers M 1  to M 4  is not picked up. 
     If the acquired video is a video of the cooking area (Yes in Act  104 ), the control unit  121  causes the wearable image processing apparatus  1  to deliver the video picked up by the digital camera  11  of the wearable image processing apparatus  1  to the advertisement terminal  36  as a video of the cooking area (Act  105 ). If the acquired video is not a video of the cooking area (No in Act  104 ), the control unit  121  causes the wearable image processing apparatus  1  to deliver the video picked up by the fixed camera  37  as a video of the cooking area (Act  106 ). Therefore, the wearable image processing apparatus  1  can deliver a lively cooking video close to the line of sight  2   b  of the wearer  2  to the advertisement terminal  36 . Even when a video picked up by the wearable image processing apparatus  1  is a video of an area other than the cooking area because of behavior of the wearer  2 , the wearable image processing apparatus  1  can always deliver a video of the cooking area to the advertisement terminal  36  by delivering a video of the fixed camera  37  to the advertisement terminal  36 . For example, in Act  105  and Act  106 , the wearable image processing apparatus  1  receives, according to the sound operation or the video operation, selection of a cooking start item as deliver setting after displaying the order information, adds order information of the cooking start item to the picked-up video of the cooking area, and delivers the order information. The order information of the cooking start item is added and delivered in order to show which food item is cooked in the video of the cooking area to be delivered. In Act  105 , while the processing in Act  103  to Act  106  is repeated until an instruction for ending the delivery is received in Act  107  explained later, when the acquired video is a video of the cooking area for a predetermined time set in advance, the wearable image processing apparatus  1  may perform zoom-up of the acquired video. Specifically, the wearable image processing apparatus  1  performs electronic zoom for trimming a predetermined area from the acquired video and enlarging the predetermined area. When the zoom-up is performed in this way, the wearable image processing apparatus  1  can acquire a livelier video. 
     Subsequently, the control unit  121  determines, according to the sound operation or the line-of-sight operation, whether an instruction for ending the delivery is received (Act  107 ). If the instruction for ending the delivery is received (Yes in Act  107 ), the control unit  121  stops the delivery of a video to the advertisement terminal  36  and advances the processing to Act  108 . If the instruction for ending the delivery is not received (No in Act  107 ), the control unit  121  advances the processing to Act  103  and continues the delivery of a video to the advertisement terminal  36 . For example, in the case of the sound operation, the control unit  121  ends the delivery of a video according to a sound command for ending the delivery of a video such as “end delivery”. In the case of the line-of-sight operation, the control unit  121  ends the delivery of a video when the control unit  121  detects that the line-of-sight marker G 1  overlaps, for a predetermined time, an icon image similar to the delivery icon G 3  as an icon image for ending the delivery of a video (not specifically shown). 
     In Act  108 , the control unit  121  determines, according to whether operation indicating completion of cooking is performed by the sound operation or the line-of-sight operation, whether cooking of all order items displayed on the monitor display unit  17  is completed (Act  108 ). If the cooking is not completed (No in Act  108 ), the control unit  121  returns the processing to Act  102 . If the cooking is completed (Yes in Act  108 ), the control unit  121  ends the display of the order items on the monitor display unit  17  (Act  109 ) and ends the processing. For example, in the case of the sound operation, the control unit  121  ends the processing according to a sound command indicating completion of cooking such as “complete cooking”. In the case of the line-of-sight operation, the control unit  121  ends the processing when the control unit  121  detects that the line-of-sight marker G 1  overlaps, for a predetermined time, an icon image similar to the delivery icon G 3  as an icon image for indicating completion of cooking (not specifically shown). Both of the completion of cooking and the completion of delivery may be performed according to one instruction by the sound operation or the line-of-sight operation. 
     In this embodiment, the wearable image processing apparatus  1  used while being mounted on the wearer  2  is explained as the example. However, the display and operation configuration in the wearable image processing apparatus  1  may be a stationary type. Specifically, the wearable image processing apparatus  1  may have, on the outside, a display such as a LCD (Liquid Crystal Display) and an operation input unit such as a touch panel or operation keys set in predetermined positions. The operation input by the user is not limited to the sound operation or the line-of-sight operation and may be performed by the touch panel or the operation keys. A host apparatus such as the order management server  30  may display monitor display of order information or the like on a display set in a predetermined position. In this case, the wearable image processing apparatus  1  does not include the monitor display unit  17  and performs the operation input as sound input. 
     Computer programs executed by the CPUs of the control unit  121  and the order management server  30  may be provided while being incorporated in the ROM or the like in advance. The computer programs may be provided while being recorded in a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a DVD as a file of an installable or executable format. 
     The computer programs may be stored on a computer connected to a network such as the Internet and provided while being downloaded through the network. The computer programs may be provided or distributed through the network such as the Internet.
