2. Description of the Related Art In recent years, the Internet has become widespread and WW
Information transmission by W (World Wide Web) and the like has been generally performed. In such a situation,
An image input device for inputting an image in real time to a computer network has been proposed and commercialized. Such an image input device basically includes a camera for photographing a subject, and a network interface for connecting the camera to the computer network in order to transmit the photographed image in real time via a computer network such as the Internet. Consists of Cameras and network interfaces that are separated include WebView / Li by Canon Inc.
Vescope System (trademark), which integrates both, Active Image UK
ng Mv-NET ™ and Swedish AX
IS Inc.'s NetEye200 (trademark).

In order to connect such a video input device to a computer network, particularly a TCP / IP-based network, before connecting to the network and starting operation, the video input device is first set as an initial parameter. It is necessary to set in advance the IP address of the video input device, the subnet mask of the network to be connected, and the route control information of the network (such as the IP address of a router existing on the network to which the device is connected). These parameters are generally different for each user,
Since it cannot be set in advance at the time of shipment, it is necessary to set according to the network to which the user himself connects.

However, since these video input devices usually do not have a keyboard, one of the following two methods is used to set various initial parameters. That is, in the first method, an input port such as an RS232C terminal is provided, a personal computer or a dumb terminal is connected thereto through a serial signal line or the like, and initial parameters are input and communicated with the personal computer or the like. Set. In the second method, an Ethernet port is provided in the video input device, and the correspondence between the Ethernet address unique to the video input device and the IP address to be set in the video input device is transmitted to the device that manages the route control information by using an ARP command. The initial parameters are temporarily registered by using a password or the like, and the initial parameters are transferred to the video input device by FTP or telnet while the registration is valid, and are set.

[0005]

That is, in the prior art, it was impossible to set the initial parameters by the video input device alone. The second method may require special use rights for other devices connected to the network,
The setting is complicated for general users.

Although the video input device itself may be provided with a plurality of switches for inputting initial parameters and a display device for displaying input values, such a device is used only for setting initial parameters. The provision of the above causes an increase in cost and an increase in the size of the housing.

If only a small number of switches can be used for inputting initial parameters, the input operation becomes complicated and difficult to understand, and input errors easily occur, which is not preferable in terms of the system configuration.

SUMMARY OF THE INVENTION It is an object of the present invention to solve such a problem and to provide an image input apparatus which can set initial parameters and other parameters independently and easily.

Another object of the present invention is to provide a video input device capable of inputting and setting various parameters without providing a special input switch or the like.

[0010]

According to the present invention, there is provided an image input apparatus, comprising: an image photographing means; an image processing means for processing an image photographed by the image photographing means; and a network for processing the image processed by the image processing means. A video input device comprising: a network interface means for outputting the image data; a parameter entry means in which at least one parameter to be set is entered is photographed by the image photographing means; It is stored in a section and set.

[0011] A parameter setting method according to the present invention comprises a video photographing means, a video processing means for processing a photographed video,
A method for setting predetermined parameters in a video input device having a network interface means for outputting the video on a network, comprising: a photographing step of photographing a parameter entry medium arranged in a field of view of the video photographing means; A collating step of collating the image photographed in the photographing step with a pattern stored in advance, a judging step of judging a value of a parameter written in the parameter entry medium from a collation result of the collating step, Storing the extracted parameters as the predetermined parameters at predetermined positions.

With this configuration, parameters to be set can be easily input and set without using other devices and without performing complicated operations. In addition, since it is not necessary to prepare a special switch or the like for inputting parameters, hardware costs can be reduced and the size of the housing can be reduced.
Input errors due to complicated operations can be reduced, and the time required for parameter setting can be reduced.

By providing a positioning guide member for placing the parameter writing medium and the image capturing means in a fixed positional relationship, the parameter writing medium and the image capturing means can be installed in an accurate positional relationship, and the contents of the parameter writing medium can be correctly written. You can shoot, and the reading accuracy will be significantly improved. An image input device having no automatic focus adjustment mechanism can use the parameter input according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is an external view of an embodiment of the present invention. Reference numeral 10 denotes a video input device main body of the present embodiment, and 12 denotes a parameter input auxiliary device for inputting parameters to the video input device main body 10. Parameter input assist device 12
A parameter writing board 14 for writing parameters to be input to the video input device main body 10;
In a standing state.

FIG. 2 is a schematic functional block diagram of the internal structure of the video input device main body 10. It can be roughly divided into three parts, namely, a video photographing unit 20, a video processing unit 22, and a network interface 24. Video shooting unit 20
Is composed of a video photographing device 26 and an automatic focus / exposure control device 28 for automatically controlling the focal length and exposure of the photographing optical system of the video photographing device 26. The video processing unit 22 includes a microprocessor 30, a ROM 32 for storing programs and the like, an arithmetic RAM 34, a flash ROM 36 for storing various parameters such as initial parameters, and a status display LED.
38 and a parameter input mode changeover switch 40, which are connected to the system bus 42. The microprocessor 30 controls the whole of the video input device main body 10 by the microprocessor 30.

In this embodiment, the parameter input board 1 of the parameter input auxiliary device 12 is
4). Then, a parameter value is extracted by processing the video obtained by shooting, and is set as a parameter of the video input device main body 10. In the following, the operation of the present embodiment will be described by taking as an example a case where parameters of the network interface 24, particularly, an IP address are set. FIG. 3 shows a video input device main body 1.
0 shows an operation flowchart.

When the power is turned on to the video input device main body 10, the microprocessor 30 checks whether or not the initial parameters have been input (S1). If the initial parameters have been input, the microprocessor 30 sets the status display L
The ED 38 is turned on (S9) to enter a standby state.

If the initial parameters have not been input (S1),
The microprocessor 30 blinks the status display LED 38 (S2). Waiting for the user to turn on the parameter input mode changeover switch 40 (S3), and when the switch 40 is turned on (S3), the microprocessor 30 reads the initial parameter setting program from the ROM 32 (S4), and sets the initial parameter setting mode. Move to

The user sets the parameter entry board 14 in advance.
Here, the value of the parameter to be set is entered according to a predetermined rule. FIG. 4 shows an example of the entry. Here, IP address: 172.16.38.25 Subnet mask: 255.255.255.0 IP address of router: 172.163.8.1 The value is set, and the value is set to 7-segment characters. Fill in the model. It should be noted that an input identifier column 14a indicating the entry content is provided on the right side of each line. Here, the upper mark indicates the IP address, the lower mark indicates the subnet mask, and the upper and lower marks indicate the IP address of the router. That is, in FIG. 4, the IP address is entered in the first line, the subnet mask is entered in the second line, and the IP address of the router is entered in the third line.

The user places the parameter entry plate 14 thus filled on the holding plate 16 and focuses the entry on the parameter plate 14 in front of the video input device body 10 as shown in FIG. Place them at a suitable distance.

The image input device main body 10 adjusts the focus of the image photographing device 26 to the parameter input assisting device 12 by the automatic focus exposure control device 28, and confirms that the image is in focus (S5). To shoot.
The photographed image data is transferred to the calculation RAM 34 and compared with the initial parameter comparison pattern stored in the ROM 32. Based on the result of the comparison, the microprocessor 30 first determines that the subject is the parameter entry board 1
4 (S6), and then recognizes the characters written on the parameter entry board 14, that is, the IP address, subnet mask, and router IP address (S7). The recognized IP address and the like are stored in a predetermined area of the initial parameter storage flash ROM 36 (S8). Then, the status display LED 38 is turned on (S9) to enter the standby state.

In FIG. 4, three types of parameters are entered at a time on one parameter entry plate 14 and photographed.
It is clear that the three types of parameters may be individually shot and stored in the flash ROM 36 sequentially.

Although not shown in FIG. 3, if the entry on the parameter entry board 14 could not be correctly recognized, if the entry on the parameter entry board 14 contains an error, Is in focus, the status display LED 38 remains blinking. In that case, the user must start over from the entry or installation of the parameter entry board.

When the status display LED 38 is lit, the video input device main body 10 is in a standby state. The lighting of the status display LED 38 indicates to the user that the initial parameters for network connection are set to be valid. After turning off the parameter input mode changeover switch 40, the user once turns off the power, checks the physical connection to the network, and turns on the power again. Thereby, the video input device main body 10 can be actually used via the network.

In FIG. 4, a 7-segment character pattern is used for entry of an IP address or the like. Of course, a finer 16-segment character pattern may be used for entry. FIG. 5 shows an example of the entry. In FIG. 5, the host name “NETCAM” is also entered so that it can be set in the video input device main body 10. In FIG. 5, the host name is entered on the first line, the IP address is entered on the second line, the subnet mask is entered on the third line, and the IP address of the router is written on the fourth line.
The address has been entered.

In FIGS. 4 and 5, a multi-segment type character pattern is used for inputting a parameter. However, a specific pattern such as a bar code may be defined and used. FIG. 6 shows an example of parameter entry using such a code system. In FIG. 6, the contents to be entered are indicated by which frame of the input identifier field is painted out. In FIG. 6, an IP address is entered. FIG. 7 shows FIG.
The correspondence between the code string indicated by and the numeral is shown. Since it is easier to regularize than characters, improvement in mechanical reading accuracy can be expected.

In the entry modes shown in FIGS. 4, 5 and 6,
There is no way to check that the contents are read correctly. For this purpose, as shown in FIG. 8, a checksum column may be provided so that it can be checked whether the read result is correct. In FIG. 8, each digit of each digit in each row is added to the checksum column after each entry column of the IP address, the subnet mask, and the router IP address, and the ones digit of the obtained value is entered.
For example, with an IP address of 172.16.38.25, 1 + 7 + 2 + 1 + 6 + 3 + 8 + 2 + 5 = 35, so 5 is entered in the checksum column of the IP address entry line.

The processor 30 performs a code recognition process
The value of this checksum is calculated from the recognized value, and the calculation result is compared with the recognition result in the checksum column. If they match, it is determined that the number has been correctly recognized, and the process ends. If not, an abnormality is indicated by keeping the status display LED 38 blinking. The user who has been notified of the abnormal state re-enters the parameter entry board 14 again, or adjusts the installation direction and distance so that the correct entry can be recognized.

By providing the checksum as described above,
An incorrect value can be prevented from being set.

In order to accurately photograph the entry range of the parameter entry plate 14, it is preferable to enter a special frame indicating the entry range and use it as a mark for character recognition. By providing the frame, not only the focus can be easily adjusted, but also the written content can be resized to a prescribed size and recognized, and the correct answer rate of pattern matching, that is, the recognition rate can be improved. FIG. 9 shows an example in which such a frame is provided in the entry range of the parameter entry plate 14. A frame (reading auxiliary frame) 60 surrounding an entry area for an IP address and the like and an input identification column is previously entered. It is preferable to attach a special color so that it can be easily identified on the photographed video. Also in FIG. 9, the IP address is entered in the first line, the subnet mask is entered in the second line, and the IP address of the router is entered in the third line.

When reading the parameters, the video input device main body 10 uses the reading auxiliary frame 60 on the parameter writing board 14 to focus on the surface of the parameter writing board 14 and shoot an image. If you have a zoom shooting mechanism,
Utilizing this, the photographing range is enlarged or reduced so that the size of the auxiliary frame 60 in the photographed image substantially matches the pattern stored for comparison.

When the image of the auxiliary frame 60 is distorted on the photographed image, the photographed image is corrected so as to eliminate the distortion, and the entry contents are recognized by pattern matching.
As a result, reading errors can be significantly reduced.

In the above embodiment, desired characters are entered by filling desired segments of the segment pattern, but handwriting may be performed according to guide lines. FIG. 10 shows an example of entry on the parameter entry board 14 using handwritten characters. Needless to say, the use of the guide lines makes the recognition easier than in the case of pure handwriting. In FIG. 10, the IP address is entered.

In the above embodiment, the program for reading the initial parameters is stored in the ROM 32. However, the program may be stored in the external auxiliary storage and read into the microprocessor if necessary. FIG. 10 is a schematic block diagram of the modified embodiment. The same components as those in FIG. 2 are denoted by the same reference numerals. Video processing unit 44
Is an input mode switch 40 from the video processing unit 22.
Has been removed. A PCMCIA slot 46 is connected to the system bus 42 outside the video processing unit 44.
PCMCIA slot 46 is connected to PCMCIA
An IA card, for example, a flash ROM card 48 for storing an initial parameter reading program is loaded as necessary.

Instead of the microprocessor 30 checking the state of the parameter input mode changeover switch 40,
The microprocessor 50 is a flash ROM card 4
Then, it is checked that the initial parameter setting program is stored in the card and the initial parameter setting program is read from the card 48, and the mode is shifted to the initial parameter setting mode. FIG. 12 shows the control flow. Processing for checking the parameter input mode changeover switch 40 (S3)
Instead, the loading of the flash ROM card 48 storing the initial parameter setting program is confirmed (S
10). Other processes are exactly the same as those in FIG.

In such a case, the program code itself read from the storage medium realizes the functions of the above-described embodiment, and the storage medium storing the program code constitutes the present invention. Will be. As the storage medium, other than the flash ROM card, for example, a floppy disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, and the like can be used.

In the embodiment shown in FIG. 1, the positional relationship between the parameter input auxiliary device 12 and the video input device main body 10 for photographing the parameter input auxiliary device 12 cannot be uniquely determined, so that their relative angles and the like are not constant. Therefore, there has been a problem that the reading accuracy of the information written on the parameter writing board 14 of the parameter input assisting device 12 is often lowered. Also,
Such a configuration is difficult to be adopted in a video input device that does not have an automatic focus adjustment mechanism because it is difficult to focus when the focal length at the time of imaging is fixed due to a slight shift in distance or the like.

FIG. 13 is an external perspective view of an embodiment in which such a problem is solved. Reference numeral 110 denotes a video input device main body of the present embodiment, and 112 denotes a parameter input auxiliary device for inputting parameters to the video input device main body 110.

The apparatus includes a parameter writing board 114 for writing parameters to be input to the apparatus 10, and a holding plate 116 for holding the parameter writing board 114 in an upright state. Reference numeral 118 denotes a positioning guide that assists in setting the video input device main body 110 and the parameter input auxiliary device 112 so as to face each other in a fixed positional relationship.

The positioning guide 118 accommodates a main body base accommodating hole 118a for accommodating the base of the main body 110 and positioning the main body 110, and a holding plate 116 for accommodating the parameter input auxiliary device 112 for accommodating the parameter input auxiliary device 112.
(Particularly, the parameter entry plate 114) is provided with a parameter input auxiliary device housing hole 118b in which the front face of the main body 110 is arranged. Needless to say, the main body base accommodation hole 118a of the positioning guide 118 and the parameter input auxiliary device accommodation hole 118b are provided in
When the zero and the parameter input assisting device 112 are installed, the positional relationship is such that the main body 110 is focused on the parameter writing surface of the parameter writing board 114 of the parameter input assisting device 112. The positioning guide 118 is
As shown in FIG. 14, the central part can be folded.

The positioning guide 118 is formed of a packing material at the time of shipping the image input device main body 110 and the parameter input auxiliary device 112, for example, a material such as styrene foam. Originally, it is a box-shaped object that can be folded in two at the center as shown in FIG. 14, and when shipped, the image input device main body 110 and the parameter input auxiliary device 112
And the like are packed, but the dents provided outside are used as holes 118a and 118b. As shown in FIG. 13, the positioning guide 118 is developed, and the holes 118a, 11
By setting the main body 110 and the parameter input auxiliary device 112 in each of the sections 8b, the parameter input auxiliary device 112 can be set at the correct distance and direction with respect to the main body 110.

FIG. 15 is a schematic functional block diagram of the internal structure of the video input device main body 110. Roughly three parts,
That is, it can be divided into an image capturing unit 120, an image processing unit 122, and a network interface 124. The video shooting unit 120 includes the video shooting device 126 and the video shooting device 1
An automatic focus / exposure controller 128 for automatically controlling the focal length and exposure of the photographing optical system 26. Video processing unit 122
Includes a microprocessor 130, a ROM 132 for storing programs and the like, an arithmetic RAM 134, and a flash RO for storing various parameters such as initial parameters.
M136, a status display LED 138, and a parameter input mode changeover switch 140, which are connected to the system bus 142,
30 controls the image input device main body 110 as a whole.

Also in this embodiment, similarly to the embodiment shown in FIG. 1 and subsequent figures, the image input device main body 110 takes an image of the parameter input auxiliary device 112 (the content of the parameter entry board 114). Then, a parameter value is extracted by processing the video obtained by shooting, and is set as a parameter of the video input device main body 110. In the following, the operation of the present embodiment will be described by taking as an example a case where a parameter of the network interface 124, particularly an IP address is set. FIG. 16 shows an operation flowchart of the video input device main body 10.

When the power of the video input device main body 110 is turned on, the microprocessor 130 checks whether the initial parameters have been input (S21). If the initial parameters have been input, the microprocessor 130 turns on the status display LED 138 (S28), and enters the standby state.

When the initial parameters have not been input (S2

Also in this embodiment, the user previously writes the value of the parameter to be set on the parameter writing board 114 in accordance with a predetermined rule. FIG. 17 shows an example of the entry. Here, IP address: 172.16.38.25 Subnet mask: 255.255.255.0 IP address of router: 172.163.8.1 The value is set, and the value is set to 7-segment characters. Fill in the model. It should be noted that an input identifier column 114a indicating the entry content is provided on the right side of each line. Here, the upper mark indicates the IP address, the lower mark indicates the subnet mask, and the upper and lower marks indicate the IP address of the router. That is, in FIG. 17, the IP address is entered in the first line, the subnet mask is entered in the second line, and the IP address of the router is entered in the third line.

The user puts the parameter writing plate 114 filled in on the holding plate 116, fits the holding plate 116 into the parameter input auxiliary device accommodating hole 118b of the positioning guide 118 as shown in FIG. The apparatus main body 110 is fitted into the main body base accommodation hole 118a. As a result, the parameter input assist device 112 is placed at a certain distance from the video input device main body 110.

The image input device main body 10 photographs the parameter writing board 14. The photographed image data is used for calculation R
The pattern is transferred to the AM 134 and compared with the initial parameter comparison pattern stored in the ROM 132. Based on the comparison result, the microprocessor 130 first confirms that the subject is the parameter entry board 114 (S2).
5) Then, the characters written on the parameter entry board 114, that is, the IP address, the subnet mask, and the IP address of the router are recognized (S26). Recognized I
The P address etc. are stored in the flash RO for storing initial parameters.

In FIG. 17, one parameter entry plate 14
In this example, three types of parameters are written at a time, and it is apparent that the three types of parameters may be individually captured and stored in the flash ROM 136 sequentially.

Although not shown in FIG. 16, if the entry on the parameter entry board 114 could not be correctly recognized, if the entry on the parameter entry board 114 contains an error, Is focused, the status display LED 138 remains blinking. In that case, the user must start over from the entry or installation of the parameter entry board.

When the status display LED 138 is lit, the video input device main body 110 is in a standby state. The lighting of the status display LED 138 indicates to the user that the initial parameters for network connection are set to be valid. After turning off the parameter input mode changeover switch 140, the user temporarily turns off the power, checks the physical connection to the network, and turns on the power again. Thus, the video input device main body 110 can be actually used via the network.

In FIG. 17, 7 is used to enter the IP address and the like.
Although the character pattern of the segment is used, a finer 16-segment character pattern may be used for writing as illustrated in FIG. Alternatively, a host name may be input. Further, instead of a multi-segment type character pattern, a code system of a specific pattern such as a bar code may be defined and used as illustrated in FIGS. 6 and 7.

In the embodiment shown in FIG. 13, the parameter writing plate 114 is held by the positioning guide 118 via the holding plate 116.
However, the parameter writing plate 114 may be directly installed on the positioning guide. FIG.
The perspective view of the modification is shown. Reference numeral 150 denotes a positioning guide that replaces the positioning guide 118.
It has a main body housing hole 150a similar to that of No. 18 and an insertion hole 150b into which the parameter writing plate 114 can be directly inserted. With this configuration, the parameter entry board 114 can be correctly aimed at the video input device 110 at a fixed distance.

[0054]

As can be easily understood from the above description, according to the present invention, various parameters such as initial parameters for connecting a video photographing / output device to a network can be input and set on a carrier. That is, various parameters can be easily set without connecting other devices or performing complicated operations for the connection.

Further, since it is not necessary to prepare a special switch or the like for inputting initial parameters, the cost of hardware can be reduced and the size of the housing can be reduced. Further, input errors due to complicated operations can be reduced, and the time required for initial parameter setting can be reduced.

By using the positioning guide, the image input device main body and the parameter input auxiliary device can be arranged in a fixed positional relationship, and the parameter reading accuracy is improved. Since the distance from each other can be suppressed within a certain error range, the parameters can be read without any trouble even with an image input device having no automatic focus adjustment mechanism.
