Is a button for switching the display between the menu screen and the imaging screen. The up button 12 and the down button 13 are buttons operated when selecting a mode or various parameters on the menu screen. The mode selection on the menu screen will be described later in detail.
The up button 12 and the down button 13 are used for zooming of a lens 307 described later on the imaging screen. The connector 16 is a connection connector for electrically connecting to and communicating with an external device.

The lens unit 2 constitutes an interchangeable lens that is detachably attached to the front part of the main unit 1. An IR lens 301 that transmits infrared rays is used for the lens unit 2. The grip unit 3 is a part that the user grips with his hand when imaging by hand. The grip section 3 is provided with a release button 31, a standby switch 32, and an alarm 33.

The release button 31 is a button that is operated to start recording of captured image information on an internal memory card (not shown) or an external memory connected via the connector 16. The release button 31 functions as a decision button when a menu screen is displayed on the LCD 606 by the menu button 14. The standby switch 32 is a switch that switches between an imaging state and an imaging standby state (standby state). The relationship between the power switch 11 and the standby switch 32 will be described later. The alarm 33 emits a sound to warn and notify.

The display unit 4 is a part to be watched for observing the imaging screen and the menu screen displayed on the LCD 606. The display unit 4 will be described with reference to FIG. FIG.
1 is an external view of the present embodiment as viewed from the back.

The display unit 4 has an LCD 606 as a color monitor. The LCD 606 visually displays the captured subject image, menu screen, and the like. The subject image is based on an output from a CMOS sensor 308 described later, and is displayed in a pseudo-colored manner according to the temperature. The details of the pseudo color conversion will be described later. In addition, the display unit 4 has an eyepiece sensor 41 that detects whether the user is in eye contact with the eyepiece unit.

Next, the optical system of this embodiment will be described. FIG. 3 is a diagram illustrating an internal optical system of the camera according to the present embodiment. The optical system inside the camera is roughly divided into an infrared unit, a lens unit, a camera unit, and a lighting unit. The infrared unit, the lens unit, and the camera unit are housed in the main body 1. The lighting unit is housed in the grip unit 3. The infrared unit has an IR lens 301, a bimaterial (BM) sensor 303, and a Peltier element 302. The lens unit has a lens 3
04. The camera unit has a reading-side pinhole 305, a lens 307, and a CMOS sensor 308. The lighting unit includes an irradiation-side pinhole 309, a prism 310, a lens 311, and an LED 312.

IR lens 301 in infrared unit
Passes infrared light and forms an image of the infrared light on the BM sensor 303. The BM sensor 303 is a sensor that detects infrared rays by arranging a plurality of bi-material (BM) pixels that are displaced by a temperature rise due to heat generated by the absorption of infrared rays in a two-dimensional manner. The image area of the BM sensor 303 has a rectangular shape with the long side in the longitudinal direction of the BM sensor 303 in FIG.

The lens 304 in the lens unit is
BM sensor 303 together with camera unit lens 307
Is formed on the CMOS sensor 308 of the camera unit. Readout pinhole 305 in camera unit
Is a pinhole for limiting the light flux from the BM sensor 303. The lens 307 is a zoom lens.
The lens 307 performs zooming by operating the up button 12 and the down button 13 in the shooting state,
The captured image displayed on D606 can be zoomed. The CMOS sensor 308 is an image sensor that receives reflected light from the BM sensor 303. The camera unit can be moved by a motor 306 to change the temperature measurement range. In the present embodiment, the entire camera unit is configured to be moved. However, the configuration may be such that only the readout pinhole 305 is moved instead of the entire camera unit.

The illumination side pinhole 3 in the illumination unit
Reference numeral 09 denotes a pinhole that restricts illumination light from the LED 312. The prism 310 bends the light beam that has passed through the lens 311 and emits it. LED 312 is a BM sensor 3
03, which emits light of a wavelength that is difficult for the BM pixel to absorb. Also, even if the LED 312 itself emits light having a wavelength that the BM pixel can easily absorb, the prism 31
0, a component that the BM pixel easily absorbs when passing through the illumination optical system of the lens 311 may be cut. Thereby, the BM pixel is displaced by the influence of the illumination light beam emitted from the LED 312, and an erroneous temperature is not detected.

The reading-side pinhole 305 and the irradiation-side pinhole 309 are arranged at positions perpendicular to the moving direction of the emission spot that moves due to the displacement of the BM pixel of the BM sensor 303. With this arrangement, even when the camera unit is moved, the irradiation-side pinhole 309 does not hinder the movement of the reading-side pinhole 305.

By changing the distance from the BM sensor 303 to the readout pinhole 305 and the distance from the BM sensor 303 to the irradiation side pinhole 309, when the camera unit is moved, the reading side pinhole 305 becomes The movement of the hole 309 is not hindered.

When the image area of the BM sensor 303 is rectangular, two pin holes 305 and 309
And the longitudinal direction of the rectangular image area are arranged vertically. When the lens 304 is small in the optical system illustrated in FIG. 3, the illumination area of the LED 312 that illuminates the BM sensor 303 is narrowed in the direction in which the two pinholes 305 and 309 are arranged due to vignetting. By making the direction in which the illumination area becomes narrower and the shorter direction of the rectangular image area the same, even if vignetting occurs, it is not necessary to uselessly increase the lens diameter of the lens 304. Can be made smaller.

Next, an electric circuit and the like formed inside the camera of this embodiment will be described. FIG. 4 is a functional block diagram illustrating functions of an electric circuit and the like configured inside the camera of the present embodiment.

The CPU 601 is electrically connected to each circuit described below, and controls the control executed by the camera. The Peltier element 302 is arranged near the BM sensor 303 and is an element for keeping the temperature near the BM sensor 303 constant. The temperature sensor 602 is a sensor that detects a temperature near the BM sensor 303. The CPU 601 determines the Peltier driver 6 based on the detection result of the temperature sensor 602.
Command 03. The Peltier driver 603 uses the CPU 6
The Peltier element 302 is driven by a command from 01.
The switch circuit 604 is a circuit connected to various switches and buttons, and transmits information on the operated switches and buttons to the CPU 601. The eyepiece driver 605 drives the eyepiece sensor 41 and outputs the output from the eyepiece sensor 41 to the CPU.
601. LCD driver 607 is CPU 60
The color liquid crystal monitor of the display unit 4 is driven by a command from the control unit 1. The motor 306 is a motor that is driven when the camera unit having the readout pinhole 305 is moved.
The motor 306 has a built-in encoder. The motor driver 611 controls the motor 3
06 is driven. Further, the motor driver 611 transmits an output from the encoder of the motor 306 to the CPU 601. Thereby, the CPU 601 can obtain the position information of the camera unit. Look-up table (LU
T) 608 is a circuit that stores various data required by the camera. The LUT 608 stores temperature value information corresponding to the output amount from each element of the CMOS sensor 308 and the position information of the camera unit. Therefore, if the output amount from the CMOS element and the position information of the camera unit are known, the temperature value of the subject corresponding to the element can be obtained. The LUT 608 stores display color information corresponding to the output amount from the CMOS element and the position information of the camera unit. Therefore, it is possible to perform a pseudo-color display indicating a color temperature distribution of a subject image described later. The CMOS driver 609 drives the CMOS sensor 308 according to a command from the CPU 601. The CMOS driver 609 detects a signal output from the CMOS sensor 308 and transmits the signal output to the CPU 601. The LED driver 610 drives the LED 312 according to a command from the CPU 601. The alarm 33 emits a warning sound by a speaker. The connector 16 is a connector connected to perform communication with another device. By connecting a Bluetooth device to this connector 16, high-speed communication with other devices can be performed wirelessly.

The camera of this embodiment can change the temperature resolution. For example, when it is desired to measure a minute change in body temperature, a pinhole having a small diameter is used to increase the temperature resolution. Since the specific operation is performed in the description of the control described later, it is omitted here. In the camera of the present embodiment, the temperature resolution is changed in three steps by using pinholes of three types, but the present invention is not limited to this, and two or five steps may be used.
A pinhole that uses the principle of changing the size of an aperture using a plurality of aperture blades, which is used in a photographing lens of some cameras, may be used. Further, by changing the diameter of the pinhole, not only the temperature resolution can be changed, but also the sensitivity and the dynamic range can be changed.

In addition to changing the size of the pinhole, the method of changing the temperature resolution can also be realized by changing the emission intensity of the LED 312 and integrating the output from the CMOS sensor 308 a plurality of times.

The control performed by the camera according to the present embodiment will be described below. First, power control will be described. The relationship between the power switch 11 and the standby switch 32 will be described. When the power switch 11 is operated, power is supplied to the CPU 601, the switch circuit 604, the Peltier element 302, the Peltier driver 603, and the temperature sensor 602. A circuit such as the Peltier element 302 requires a certain amount of time from when power is supplied until the circuit becomes stable. Once the power is turned off, it is necessary to wait for a while until the next measurement becomes possible, which may hinder the measurement. Therefore, the power switch 11 is kept on except when it is not used for a long time. When the standby switch 32 is operated, the CMOS sensor 308 and the LCD 6
06, LEDs 312 and their driver circuits. CMOS sensor 308, LCD 606, LE
D312 and their driver circuits become stable in a short time after power is supplied. Therefore, even if it is frequently turned on and off, the measurement is not hindered, and the energy can be saved by turning it off when it is not used for a short time. By using the two-step power-on method, energy saving and practicality can be obtained. Hereinafter, the power supply control will be specifically described.

FIG. 5 is a flowchart for explaining power control performed by the camera of the present embodiment. The control of this flow is executed by the CPU 601. Also,
This flow starts when the power switch 11 is turned on.

In step S11, the Peltier device 30
2. Power is supplied to the Peltier driver 603 and the temperature sensor 602. In step S12, it is detected whether or not the standby switch 32 has been turned on. If the switch has been turned on, the process proceeds to step S13. If not, the process proceeds to step S16. In step S13, the CMOS sensor 308, L
Power is supplied to the CD 606, the LED 312, and their driver circuits. In step S14, it is detected whether or not the standby switch 32 has been turned off. If the switch has been turned off, the process proceeds to step S15, and if not, the process proceeds to step S16. In step S15, the CMOS sensor 308, LCD 606, LED 31
2 and the supply of power to these driver circuits is stopped.
In step S16, it is detected whether or not the power switch 11 is turned off. If the power switch 11 is turned off, the process proceeds to step S17. If not, the process returns to step S12. In step S17, power supply to all circuits is stopped, and the present flow ends.

In this embodiment, the CMOS sensor 308, LCD 606, LED 31
2 and all the driver circuits, the power supply is stopped, but only one of the circuits may be used.

The camera according to the present embodiment can set various modes. The various modes will be described below. Various modes can be set by operating the menu button 14. FIG. 6 shows an example of a menu screen displayed on the LCD 606 when the menu button 14 is operated. FIG. 6 shows a display example when the simple temperature setting mode is selected as the mode.

First, the temperature setting mode will be described.
By pressing the menu button 14 and operating the up button 12 or the down button 13 with the menu screen displayed on the LCD 606 to select the temperature setting mode, and pressing the release button 31, the temperature value to be measured can be selected. Becomes By operating the up button 12 or the down button 13 in this state, a temperature value that has been raised or lowered one by one is selected. By selecting a temperature value and operating the release button 31, the camera unit is moved so that the selected temperature value becomes the center value of the temperature measurement range, and the LCD 606 is switched from the menu screen to the imaging screen to switch the temperature setting mode. The setting ends. The relationship between the temperature value and the position of the camera unit is stored in the LUT 608 in advance.

Next, the simple temperature setting mode will be described. By selecting the simple temperature setting mode on the menu screen, pressing the release button 31, and operating the up button 12 or the down button 13, "air conditioner summer", "air conditioner winter", "body temperature", "bath", "hot water", "fire" Etc. can be selected. By selecting and operating the release button 31, the camera unit is moved so that the selected simple temperature value becomes the center value of the temperature measurement range, and the LCD 606 is switched from the menu screen to the imaging screen to set the simple temperature setting mode. finish. Here, unlike the temperature setting mode, a temperature value that is likely to be used frequently without setting a temperature value is stored as a simple temperature value, and can be selected from the simple temperature values. Thereby, the setting time can be shortened. After setting in this simple temperature setting mode, if you select the temperature setting mode again on the menu screen,
The temperature value can be finely adjusted based on the temperature value set in the simple temperature setting mode.

A similar effect can be obtained by operating the one-touch button 15. Every time the one touch button 15 is operated, "Air conditioner summer""Air conditioner winter"
Switches between "body temperature", "bath", "hot water" and "fire".

Further, by registering the optimum temperature for each type of food at a restaurant or the like, and switching the one-touch button 15 to measure the temperature in accordance with the food, it is possible to provide the customer with the optimum temperature.

Further, in conjunction with an air conditioner (remote control of the air conditioner), the operation of the air conditioner can be stopped when a predetermined temperature is reached. In cooperation with the bath water heater, you can also control the amount of hot water. Thus, it can be used as a thermosensor whose operation is simple.

In this embodiment, the up button 12 and the down button 13 are used to change the setting. However, the setting may be changed using a dial according to the amount of rotation of the dial.

Next, the monitoring setting mode will be described. In the present embodiment, the modes that can be set in the monitoring setting mode are a fire prevention mode, a crime prevention mode, a disaster prevention mode, and a care mode. The setting method is the same as that of the temperature setting mode and the simple temperature setting mode, and the description is omitted.

The fire prevention mode will be described. The fire prevention mode is a mode for monitoring the occurrence of a fire. Detects the presence of an object of 300 degrees or more. In the present embodiment, the presence of an object having a temperature of 300 ° C. or more is detected as a condition for monitoring the occurrence of a fire. The presence may be detected. Hereinafter, the fire prevention mode will be specifically described with reference to FIG. FIG. 7 is a flowchart illustrating control executed when the fire prevention mode is set.

In step S21, the read-side pinhole 3
05 is moved to the position of the temperature measurement range where the object of 300 degrees can be detected by the largest pinhole. The reason for using the largest pinhole is to monitor in the widest possible temperature range. In step S22, a value corresponding to the position of the read-side pinhole 305 and the output of the CMOS sensor 308 is obtained from the LUT 608, and the color and temperature values corresponding to the values are adjusted so as to be displayed on the display unit 4. In step S23, it is detected whether or not the output of the CMOS sensor 308 has changed. When a change is detected, the process proceeds to step S24, and when no change is detected, step S23 is repeated. In step S24, it is detected whether there is an object of 300 degrees or more. If there is, proceed to step S25,
Since there is a high possibility that the detected object is a fire, an alarm is sounded to notify the observer, and the process returns to step S23 to continue monitoring. If there is no object of 300 degrees or more, there is a possibility that it is not a fire, so the process returns to step S23 to continue monitoring.

Next, the security mode will be described. The security mode is a mode in which a suspicious person is monitored for intrusion. Body temperature 3
When an object with a temperature close to 6 degrees is detected to come into the camera frame, an alarm sounds and the observer is notified. The reason for alarming at the frame-in is that there is a possibility that an intruder exists due to the frame-in of the object. Hereinafter, the crime prevention mode will be specifically described with reference to FIG. FIG. 8 is a flowchart illustrating control executed when the security mode is set.

In step S31, the read-side pinhole 3
05 is moved to the position of the temperature measuring range where the object of 36 degrees can be detected by the pinhole of the second size. The reason for using the second largest pinhole is that most people have 36
This is because the body temperature is in the vicinity of degrees, and it is desired to monitor the temperature in a somewhat narrow temperature measurement range. In step S32, a value corresponding to the position of the read-side pinhole 305 and the output of the CMOS sensor 308 is obtained from the LUT 608, and the color and temperature values corresponding to the values are adjusted so that they can be displayed on the display unit 4. In step S33, it is detected whether or not the output of the CMOS sensor 308 has changed. When a change is detected, the process proceeds to step S34, and when no change is detected, step S33 is repeated. In step S34, it is detected whether an object near 36 degrees has entered the frame. If it is detected, the process proceeds to step S35, and since there is a high possibility that a person has entered, an alarm is sounded to notify the observer, and the process returns to step S23 to continue monitoring. If not detected, the process returns to step S23 to continue monitoring.

Next, the disaster prevention mode will be described. The disaster prevention mode is a mode for monitoring both crime prevention and fire prevention. The security temperature range and the fire temperature range are switched and monitored at predetermined intervals. In other words, the reading-side pinhole 305 is moved at predetermined time intervals so as to monitor both the 36-degree and 300-degree subjects, and the temperature measurement range is repeatedly changed.
Then, when a subject having one of the temperatures is detected, monitoring is continued with the detected temperature measurement range fixed. Hereinafter, the disaster prevention mode will be specifically described with reference to FIG. FIG. 9 is a flowchart illustrating control executed when the disaster prevention mode is set.

In step S41, the above-described fire prevention mode control is performed. In step S42, it is determined whether a fire has been detected in step S41. If a fire has been detected, monitoring in the fire prevention mode is continued, and if no fire has been detected, the flow proceeds to step S43. Step S4
At 3, it is detected whether or not a predetermined time has elapsed. If it has elapsed, the process proceeds to step S44, and if it has not elapsed, monitoring in the fire prevention mode is continued.

In step S44, the above-described security mode control is performed. In step S45, it is determined whether an intruder has been detected in step S44. If an intruder has been detected, monitoring in the security mode is continued, and if no intruder has been detected, the process proceeds to step S46. In step S46, it is detected whether a predetermined time has elapsed. When the time has elapsed, the process returns to step S41, and the monitoring is switched to the fire prevention mode. When the time has not elapsed, the monitoring in the security mode is continued.

Next, the care mode will be described. The care mode is a mode for monitoring the safety of the person being cared for.
When an object with a temperature close to the body temperature detects a flame-out, an alarm sounds and the monitor is notified. The reason for alarming at the frame out is that the caregiver falls from the bed,
This is because they may have left the room.
If there is a cohabitant, when the frame goes out, the alarm of the camera itself is warned so that the cohabitant can understand,
A fixed telephone 707 and a mobile telephone 708 are called. If you live alone without a cohabitant, report to the care company directly.

Also, an alarm can be issued for a subtle change in body temperature, or a notification can be sent to a hospital. For example, if the body temperature goes above or below normal fever, the caregiver may be ill. Further, a warning may be issued even when the user has not moved for a predetermined time. If a change in body temperature is detected, a notification is sent to the cohabitant and the hospital at the same time. In this case, there is a possibility of developing into an emergency situation, so report to the hospital directly regardless of the presence of cohabitants.

As described above, it is possible to promptly deal with the problem by notifying an appropriate contact according to the detection result, and it is possible to maximize the safety of the caregiver. Hereinafter, the care mode will be specifically described with reference to FIG. FIG. 10 is a flowchart illustrating the control performed by setting the care mode.

In step S51, the read-side pinhole 3
05 is moved to the position of the temperature measurement range where the object of 36 degrees can be detected by the smallest pinhole. The reason for using the smallest pinhole is to monitor temperature changes as subtle as possible. In step S52, a value corresponding to the position of the read-side pinhole 305 and the output of the CMOS sensor 308 is obtained from the LUT 608, and the color and temperature values corresponding to the values are adjusted so as to be displayed on the display unit 4. In step S53, it is detected whether or not the output of the CMOS sensor 308 has changed. When a change is detected, the process proceeds to step S54, and when no change is detected, step S53 is repeated. In step S54, it is detected whether or not the temperature of the object around 36 degrees has changed. If there is a temperature change, the process proceeds to step S55, where the caregiver is likely to be ill, so that the alarm of the camera is sounded to notify the cohabitants and notify the registered hospital. If there is no temperature change, it is detected whether or not an object near 36 degrees has gone out of frame. When the frame-out is detected, the process proceeds to step S57, and when the frame-out is not detected, the process returns to step S53 to continue the monitoring. In step S57, it is confirmed whether or not the care receiver has a cohabitant. If there is a cohabitant, the process proceeds to step S58, and an alarm of the camera is sounded to notify the cohabitant. If there is no cohabitant, the process proceeds to step S59, and a notification is sent to the directly registered care company.

There is an automatic temperature measurement range adjustment as a mode which can be set in "other" on the menu screen. Hereinafter, the automatic temperature measurement range adjustment will be described.

For example, when the displacement of the BM pixel located at the center exceeds a predetermined value in the currently set temperature measuring range, the reading side pinhole 305 is set to a temperature measuring range capable of measuring high or low temperature. Change to position. And
The position of the camera unit is moved so that the output value of the CMOS element located at the center of the CMOS sensor 308 is always maximized. By doing so, measurement can be performed while automatically adjusting the temperature measurement range. Hereinafter, the automatic temperature measurement range adjustment control will be specifically described with reference to FIG. FIG. 11 is a flowchart showing automatic temperature measurement range adjustment control. The flow shown in FIG. 11 is repeatedly executed when the automatic level adjustment is set.

In step S21, the CMOS sensor 30
The output value of the CMOS device located at the center of 8 is extracted. In step S22, it is determined whether or not the extracted output value is equal to or less than a predetermined value.
The process proceeds to step S3, and if the value is the predetermined value, the process returns to step S21. In step S23, the camera unit is moved in a direction in which the lower temperature range can be measured. In step S24, C
It is detected whether the output value of the MOS element has recovered to a predetermined value. If not recovered, the process proceeds to step S25, and if recovered, the process proceeds to step S27. In step S25, the camera unit is moved this time in a direction in which a higher temperature range can be measured. In step S26, the CMO
It is detected whether the output value of the S element has recovered to a predetermined value.
If not recovered, the process returns to step S23 to move the camera unit, and if recovered, the process proceeds to step S27. In step S27, a temperature value corresponding to the output value of the CMOS element at the center of the CMOS sensor 308 and the position information of the camera unit acquired from the encoder of the motor 306 is acquired from the LUT 608. Further, the LCD 60
6 shows the temperature value acquired as the temperature value of the central part.

As described above, by using the automatic temperature measurement range adjustment function, it is possible to automatically observe an object whose temperature changes without manually setting the temperature measurement range. In addition,
In the above embodiment, since the subject to be measured is often located at the center, the output value of the CMOS element located at the center of the CMOS sensor 308 is extracted. However, a predetermined position may be arbitrarily selected instead of the center. In the above embodiment, the predetermined value is the maximum value of the output of the CMOS sensor 308. However, the predetermined value is not necessarily required to be the maximum value.

Further, there is a pseudo color display as a mode which can be set in "other" on the menu screen. For example, a thermographic camera or the like performs color display of a temperature distribution in which a high temperature portion is red and a low temperature portion is blue. The camera of this embodiment can also perform pseudo color display. By displaying on the LCD 606 a display color corresponding to the amount of displacement of each BM pixel of the BM sensor 303, the temperature distribution can be expressed in color. BM
The relationship between the pixel displacement and the display color may be stored in the LUT 608 in advance. However, in the present embodiment, the displacement amount of the BM pixel is obtained from the position information of the camera unit that moves with the change of the temperature measurement range and the output amount from each element of the CMOS sensor 308. Therefore, the display color is directly determined from the position information of the camera unit and the output amount from the CMOS sensor 308 such that the display color is directly determined.
It is stored in the UT 608. Hereinafter, the pseudo color display control will be specifically described with reference to FIG.

FIG. 12 is a flowchart showing the pseudo color display control performed in the present embodiment. Step S
At 1101, the current position information of the camera unit having the read-side pinhole 305 is acquired from the encoder of the motor 306. In step S1102, the output amount from each element of the CMOS sensor 308 is obtained. In step S1103, the display color and temperature value corresponding to the position information of the camera unit acquired in step S1101 and the output amount from each element of the CMOS sensor 308 acquired in step S1102 are acquired from the LUT 608.
In step S1104, a temperature distribution is created from the display color information acquired from the LUT 608, and the LCD 606 displays the imaging screen as a temperature distribution screen. Further, for example, when the temperature value at the center of the imaging screen is set to be displayed, the temperature value acquired from the LUT 608 is displayed on the LCD 606.
To be displayed. Repeat while this flow is set to be displayed.

The camera of the first embodiment also has excellent features when used as a night scope (night vision camera). The excellent features are described below. For example, if the display light leaks outside when monitoring animals etc. in the dark, the face of the monitor is illuminated by the leaked display light,
There is a possibility that monitoring may not be successful because the monitoring target is noticed. To prevent this, the camera of the present embodiment detects that the user has taken his / her eye off the eyepiece so that the display light from the LCD 606 does not leak to the outside, and controls the LCD 606 to turn off the display. Whether or not you are eye-
It is detected by an eyepiece sensor 41 provided in an eyepiece part of the display unit 4. Further, when the imaging data is not output to the outside of the apparatus using the connector 16, the imaging itself is not necessary, so that the display on the LCD 606 is not only turned off but also switched to the above-described standby state. When the eyepiece is detected again, the display on the LCD 606 is restarted. This will be specifically described below with reference to FIG. FIG. 13 is a flowchart illustrating eyepiece control according to the present embodiment.

In step S1001, it is detected whether or not the camera is in a standby state. When it is in the standby state, the process proceeds to step S1002, and when it is not in the standby state, the process proceeds to step S1006. Step S
In step 1002, the eyepiece sensor 41 detects whether the eyepiece is in contact with the eyepiece. When the eye is in contact, the process returns to step S1001, and when the eye is not in contact, the process proceeds to step S1003. In step S1003, it is detected whether or not the imaging data is output to the outside of the apparatus using the connector 16. If the imaging data is being output, the flow advances to step S1004 to stop power supply to the LCD 606 and the LCD driver 607. If image data has not been output, the process proceeds to step S1005, and C
The power supply to the MOS sensor 308, the LCD 606, the LED 312, and their driver circuits is stopped to enter a standby state. In step S1006, the power switch 1
1 is operated to turn off the power. If the power is not turned off, the process returns to step S1001. If the power is turned off, the flow ends.

Further, a convex portion is provided around the power switch so that the operation can be performed without errors even in the dark. Instead of providing a convex portion around the switch, a fluorescent display may be given to make the switch visible even in the dark, or the switch may have a shape different from other operation buttons.

There is a remote controller connected to the camera by wire or wirelessly. The remote control has buttons formed of a transparent resin, and has a built-in light source such as an LED 312 that emits infrared rays. By making the button emit infrared light in this way, operation can be performed even in darkness by looking at the remote control while looking into the camera. Also, by attaching an LED that emits infrared rays to camera accessories (peripheral devices) such as interchangeable lenses, accessories can be easily found even in darkness. Further, if an infrared LED is provided in the mounting index portion with the camera, it can be easily mounted.

By taking measures against darkness as described above, the operability of the observer is improved even in darkness, and there is no hindrance to monitoring activities. Further, an example will be described in which the camera of the present embodiment is compact when carried. FIG.
FIG. 3 is a diagram showing a configuration in which the camera body 1 can be bent in parallel to the bottom surface of the camera body 1. In this way, by making the grip part 4 bendable, it is possible to reduce the size when carrying. Hereinafter, a second embodiment of the present invention will be described. In the above-described first embodiment, the output of the CMOS sensor 308 is processed and displayed on the LCD 606 so that the displacement of the BM sensor 303 can be visually checked. In the second embodiment, the light emitted from the BM sensor 303 is directly viewed without using the CMOS sensor 308 and the LCD 606 so that the displacement amount of the BM sensor 303 can be visually checked.

A camera according to the second embodiment will be described with reference to FIGS. In FIGS. 15 and 16, the components denoted by the same reference numerals as those in FIGS. 3 and 4 of the first embodiment perform the same functions, and thus description thereof will be omitted. The appearance of the camera according to the second embodiment is the same as that shown in FIGS. 1 and 2 of the first embodiment.

Hereinafter, a configuration of the second embodiment that is different from that of the first embodiment will be described. An LCD 606, an LCD driver 607, a CMOS
The difference is that the sensor 308 and the CMOS driver 609 are not provided. Further, although image data captured by the connector 16 cannot be output to the outside, communication with an external device is not possible with the first device.
This can be performed in the same manner as in the embodiment. If an external display device is connected to the connector 16, menu settings can be made on the menu screen as in the first embodiment.

With this configuration, a more compact and lightweight camera can be realized. In the power supply control and the eyepiece control according to the first embodiment, the standby state is the CMOS sensor 308, the LCD 60
6, supply of power to the LEDs 312 and their driver circuits has been stopped. In the second embodiment, the LED 312,
By controlling the power supply to the LED driver 610 to be stopped, power supply control and eyepiece control can be realized as in the first embodiment. Hereinafter, a third embodiment of the present invention will be described.

FIG. 17 shows a monitoring system according to a third embodiment of the present invention. This monitoring system is a system for monitoring safety at home. Set-top box (S
The TB) 701 is a device for inputting signals from inside and outside the home. In addition, the STB 70 in the present embodiment
No. 1 enables centralized control of digital home appliances in a home. The control device for controlling digital home appliances is S
You may provide separately from TB701. Surveillance camera 702 is connected to STB 701 and operates according to the conditions set in STB 701. The monitoring camera 702 is the same as the camera described in the first embodiment, and a description thereof will be omitted. As described above, by being connected to the STB 701 that controls another digital home appliance, various additional controls can be performed in cooperation with the other digital home appliance. In the present embodiment, STB 701 includes, in addition to surveillance camera 702,
Hard disk (HD) recorder 704, TV 70
5. It is communicably connected to the audio device 706, the fixed telephone 707, and the mobile phone 708, and can control each device. STB701 is a security company 7
10. It can communicate with the external computer server 709, and can directly notify the security company 710 or the like. Further, communication with a security company or the like 710 can be performed via the fixed telephone 707.

In the surveillance camera 702 of this embodiment, a Bluetooth device 703 is connected to the connector 16.
The monitoring camera 702 and the STB 701 perform wireless communication using the Bluetooth device 703, respectively. Mobile phone 7
If the Bluetooth device is provided in another device such as 08, wireless communication can be performed between the STBs 701 by Bluetooth. A monitoring system using these devices will be described below. Not all of these devices are required.
For example, even if there is no HD recorder 704, the HD recorder 7
04 can be realized as a monitoring system without the functions obtained by using the system.

An image captured by the surveillance camera 702 is recorded on the HD recorder 704 for use as evidence and verification. The HD recorder 704 is used when recording a normal television broadcast program. By using the HD for recording a broadcast program for recording a monitoring image, there is no need to newly prepare for monitoring. The HD recorder 704 includes a buffer memory for temporarily storing image data for a predetermined time, and constantly overwrites and stores the image data in the buffer memory. When a person is detected, the image data stored in the buffer memory from a predetermined time before the detection to the time of detection is instantly stored in the HD, and the image data captured by the monitoring camera 702 is stored in the HD in real time. As a result, all the actions of the person can be stored throughout. In addition,
Instead of using the buffer memory, a part of the HD may be used to temporarily store image data for a predetermined time. When the free space of the HD recorder 704 is exhausted, it is transmitted to a remote location such as an external computer server 709 using a communication line and stored. HD recorder 70
In step 4, even when the broadcast program data is being recorded and the image data from the surveillance camera 702 cannot be stored, it is transmitted to a remote location and stored. Further, the monitoring image data may be stored prior to the recording of the broadcast program data. Alternatively, both the broadcast program and the image data from the monitoring camera 702 may be stored simultaneously on two screens.

The control by the STB 701 will be specifically described below with reference to a flowchart. FIG.
FIG. 7 is a flowchart showing main control executed in TB701. This flow is always executed while the monitoring camera 702 is operating.

A step S91 detects whether or not a person detection signal has been received from the monitoring camera 702. If the signal has been received, the process proceeds to a step S92. If not, the detection of the reception is continued.

In step S92, it is detected whether or not the setting to be executed in accordance with the time is made among the various controls executed when the person is detected. The setting to be executed according to the time is a setting that changes the control to be executed according to the time at which the monitoring camera 702 detects a person. As a setting example, when the time when the monitoring camera 702 detects a person is in the time zone from 8:00 am to 10:00 pm, the TV control described later is executed, and when the detected time is in other time zones, security is immediately performed. Make a report to the company or police. The setting is made in advance by the user. If the setting has been made, the process proceeds to step S93. If the setting has not been made, the process proceeds to step S95. In step S93, the current time is obtained. In step S94, the control to be performed at the current time is set. For example, if the current time acquired in step S93 is 11:00 am, STB7
01 sets the image data so that the television control is executed, and immediately notifies when the current time is 11:00 pm. The reason for changing the control in accordance with the time in this way is that there are many visitors such as mail delivery and newspaper delivery in the daytime and few such visitors in the nighttime, and the person detected by the surveillance camera 702 depends on the detected time zone. The probability of being a suspicious person is different. In the daytime, the security company or police can be notified after confirming the detected person,
Since the person sleeps at night, it is difficult to confirm the detected person.

In step S95, it is detected whether the person at home is at home or absent. As for the detection method, it is only necessary to manually switch on and off each time a person enters the house when leaving the house. You may. In addition,
When the person detected by the surveillance camera 702 is a suspicious individual, it is determined that the child is absent even if a child or the like who cannot cope is at home. If at home, step S96
The process proceeds to step S7 if the user is not present. In step S96, the control is set to be performed when the user is at home.
At 97, the control to be performed when the user is away is set. For example, if the surveillance camera 702 detects a person in the absence, the security company or the police are set to immediately report the situation. If the surveillance camera 702 detects a person in the home, television control described later is executed. Set to. The reason for changing the control between the case where the user is at home and the case where the user is away from home is as follows.
This is because when a person is detected in 02, there is a difference that the person can be confirmed at home, but cannot be confirmed in the absence.

In step S98, each control described later is executed. Note that, in addition to each control described later, the monitoring camera 70
There is a control to notify the security company or the police immediately when the person 2 detects a person, but a description is omitted since it has already been described in this flow.

FIG. 19 is a flowchart showing HD recorder control executed by STB 701. STB70
1 will be specifically described.
In step S101, step S9 of the flow of FIG.
4. In steps S96 and S97, the monitoring camera 7
02, it is detected whether or not it is set to record on the HD recorder 704 when a person is detected. If it has been set, the process proceeds to step S102, and if it has not been set, this flow ends. Step S102
Detects whether recording is possible on the HD recorder 704 or not. When the storage capacity of the HD recorder 704 is not enough, it is detected that recording is not possible when recording a broadcast program or the like. If the recording is possible, the process proceeds to step S103, and the image data captured by the monitoring camera 702 is recorded on the HD recorder 704 together with the image data in the buffer memory. Surveillance camera 7 for recording on HD recorder 704
The surveillance image data from 02 is stored so as to be easily distinguished from broadcast program data. For example, the file name may include a character string related to monitoring, or the icon displayed on the television monitor may be different from the data of the broadcast program. FIG. 20 shows a display example displayed on a television monitor. In this way, even if a large number of image data are present in the HD recorder 704, the monitoring image data can be selected and reproduced without being lost. A series of monitoring image data continuously captured by the monitoring camera 702 is recorded as one file.

If recording is not possible, the flow advances to step S104 to connect to a predetermined computer server using a communication line such as a fixed telephone 707.
At 05, the image data captured by the monitoring camera 702 is stored in the memory of the computer server together with the image data in the buffer memory. It is detected in step S106 whether a stop operation has been performed. If the stop operation has been performed, the process proceeds to step S107. If the stop operation has not been performed, the process proceeds to step S108. In step S108, the monitoring camera 7
02 to detect whether the person is no longer detected,
If no longer detected, the process proceeds to step S107,
If the detection of a person is continued, step S10
Return to 2. In step S107, recording is stopped.

FIG. 21 is a flowchart showing television control executed in STB 701. The control of the television 705 by the STB 701 will be specifically described. In step S201, step S94 of the flow of FIG.
In steps S96 and S97, the monitoring camera 702
Is set to display on the TV monitor when a person is detected. If it has been set, the process proceeds to step S202, and if it has not been set, this flow ends.

In step S202, the monitor is turned on when the television monitor is not on, and the monitor display is switched to the image from the monitoring camera 702 when the television monitor is on. In this way, turning on the television monitor when a person is detected by the monitoring camera 702 alerts the occupant, and has the effect of making the detected person appear to be occupied even if he is away. Step S
At 203, an alarm is issued from the television speaker to call attention. In step S203, a menu having a plurality of items in addition to the image from the monitoring camera 702 is displayed on the television monitor. FIG. 22 shows a display example displayed on a television monitor.

Among the items that can be selected in the menu display shown in FIG. 22, "door unlock" is an item that is selected when it is confirmed that the person detected by the monitoring camera 702 is an acquaintance of a family member or the like. , Unlock the entrance door. “Talk” is an item selected when the user wants to have a conversation with the person detected by the monitoring camera 702. The “report” is an item selected when the person detected by the monitoring camera 702 is considered to be a suspicious person, and reports to a preset destination such as a security company or police. “Light on” turns on a light at a preset location such as a door. “Alarm” sounds an alarm provided in the camera. Both “light-on” and “alarm” are performed in the sense of warning a person detected by the monitoring camera 702. “Recording off” is an item selected when stopping recording on the HD recorder 704 or the like when it is confirmed that the person detected by the monitoring camera 702 is not a suspicious person. These items are selected by operating the corresponding channel buttons on the TV remote control.

In step S205, it is detected whether or not an item selection operation has been performed on the menu display. If the operation has been performed, the process advances to step S206 to control the selected item. When the selected control ends, the television 7
05 is returned to the original state. If the predetermined time has elapsed without performing any operation on the item, the process proceeds to step S207, and a notification is sent to a preset destination such as a security company or the police.

FIG. 23 is a flowchart showing the control of the mobile phone executed in STB 701. The mobile phone control by the STB 701 will be specifically described. In step S301, it is detected in step S94, step S96, and step S97 in the flow of FIG. 18 whether or not the setting is made to notify the mobile phone 708 when a person is detected by the monitoring camera 702. If it has been set, the process proceeds to step S302, and if it has not been set, this flow ends.

In step S302, a call is made to the mobile phone 708 to which the notification has been set by extension. Here, the extension means, for example, a home wireless LA using Bluetooth.
N connection. If wireless connection can be established by Bluetooth, highly reliable high-speed communication can be performed.
Also, since no public line is used, no communication fee is charged. In step S303, it is detected whether or not the mobile phone 708 can be connected, and the process proceeds to step S305 in a connectable state. If not, the process proceeds to step S304. In step S304, a call is made to the mobile phone 708 using the public line. In step S305, it is detected whether or not the mobile phone 708 has been connected. If the mobile phone 708 has been connected, the process proceeds to step S306. If the mobile phone 708 has not been connected for a predetermined time, the process proceeds to step S309.
Even if the mobile phone 708 is connected, if it is an answering machine, the process proceeds to step S309.

In step S306, the monitoring camera 702
Is transmitted, and further, a menu image is transmitted. The menu image is for selecting the same items as those displayed on the television monitor of FIG. 22 described above. In step S307, it is detected whether an item selection operation has been performed on the menu display. If the operation has been performed, the process advances to step S308 to control the selected item. Upon completion of the selected control, the mobile phone 708
Disconnect from the connection. If the predetermined time has elapsed without the operation of the item, the process proceeds to step S309, and a notification is made to a preset destination such as a security company or the police.

As described above, when connecting to the mobile phone 708, it is first detected whether or not an internal line can be connected using Bluetooth or the like. did.

When a plurality of devices such as the television 705 and the mobile phone 708 are set to notify the detection of a person by the monitoring camera 702, when any one device selects an item from the menu, End the notification to other devices.

In this embodiment, Bluetooth has been described as a home wireless LAN, but other home wireless LANs may be used. For example, IEEE 802.1
In 1e, priorities can be given to the signals to be communicated, so that the signals of the monitoring system having urgency are communicated with a higher priority.

FIG. 24 is a flow chart showing the alarm control executed in STB 701. The alarm control by the STB 701 will be specifically described. In step S401, in steps S94, S96, and S97 of the flow of FIG. 18, it is detected whether or not an alarm is set to sound when a person is detected by the monitoring camera 702. If it has been set, the process proceeds to step S402, and if it has not been set, this flow ends.

In step S402, the set alarm is executed. For example, when it is set to turn on the entrance light, the entrance light is turned on. Sounds the alarm if the camera's built-in alarm is set to sound. If the audio device 706 is set to sound, the audio system is sounded. If a plurality of operations are set to be performed simultaneously, a plurality of operations are performed simultaneously. In step S403, it is detected whether or not an operation for stopping the alarm has been performed. If the stop operation has been performed, the process proceeds to step S404. If the stop operation has not been performed, the process returns to step S402. In step S404, the alarm is stopped. Next, a fourth embodiment of the present invention will be described. In the fourth embodiment, the BM sensor is illuminated by LEDs of a plurality of colors, and the light emitted from the BM sensor is received by the color image sensor.

FIG. 25 is a perspective view showing an internal optical system of a camera realized using LEDs of three colors RGB. The pinhole plate 106 includes three incident pinholes PIN-BI and PIN-BI.
GI, PIN-RI and three injection pinholes PIN-BO, PIN-GO,
The PIN-RO is open. Blue light source LED-B, green light source LED-G, red light source LED-R are on the right side of the incident pinhole, respectively.
Is arranged.

The light emitted from the blue light source LED-B passes through the pinhole PIN-BI for incidence, is condensed by the lens 105, is reflected by the reflector of the BM sensor 101, is again condensed by the lens 105, and is emitted. The image passes through the pinhole PIN-BO and is formed on the color image sensor 111 by the lens 110. Green light source LED-
G, light emitted from the red light source LED-R also forms an image on the color image sensor 111 in the same manner.

Here, if the six pinholes are arranged concentrically on the pinhole plate 106, the image formed by each color becomes the same. The embodiment of the present invention is characterized in that six pinholes are not arranged concentrically on the pinhole plate 106. In other words, the pinholes PIN-BI and PIN-BO for blue
It is arranged so that the low-temperature side range can be imaged compared to the pinholes PIN-GI and PIN-GO for green. In addition, the pinholes PIN-RI and PIN-RO for red are the pinholes PIN-GI and PI for green.
Arrange so that the high temperature range can be imaged compared to N-GO. For example, the temperature measurement range that can be measured in blue is -20 to 20 degrees, and the temperature measurement range that can be measured in green is 0 to 40 degrees.
The temperature measurement range that can be measured in degrees and red is in the range of 20 to 60 degrees, and the output is maximized at a temperature in the middle of the range.

FIG. 26 shows the state of output at that time. FIG.
FIG. 6 is a diagram showing the relationship between the output of each color and the temperature. The output of the blue output increases from -20 degrees to 0 degrees, and decreases from 0 degrees to 20 degrees. Green output from 0 degrees to 20
The output increases up to degrees, and decreases from 20 to 40 degrees. The red output increases from 20 degrees to 40 degrees, and decreases from 40 degrees to 60 degrees.

If the image sensor that receives light can output RGB independently, the temperature can be determined from the ratio of each output. For example, if the blue output is 50%, the green output is 50%, and the red output is 0%, the angle is 10 degrees.

Further, when the RGB output is connected to a monitor and displayed, the color becomes different at any temperature, so that a pseudo color display can be performed. Further, in a camera using only LEDs of a single color, the range in which the luminance changes monotonically is only 20 degrees in this example. However, in the camera of this embodiment, 80
A range of degrees can be detected. If N-color LEDs are used, a range of N + 1 times can be detected, and the temperature measurement dynamic range can be widened.

Although the present embodiment has been described with reference to RGB, there is no problem with a complementary color system. If the pseudo color display is not required, the dynamic range can be increased by increasing the number of colors.

Although the image sensor has been described as a single color plate system, there is no problem with a two-plate or three-plate system.
