Each of the above-described components of the portable information communication terminal 200 is housed in portable cases (cases) 33a and 33b. 5 and 6
Then, although the portable information terminal of the form provided with the housings 33a and 33b and folding in the center part was shown, the shape is not ask | required, A slide type, an integrated type, etc. may be sufficient.

In order to perform information communication, the portable information communication terminal 200 is configured so that the information communication module 21
Connected to U7a. The information communication module 21 is connected with a speaker 25, a microphone 27, and an antenna 29. The information communication module 21 is configured such that information communication such as a telephone call and an e-mail can be performed in the portable information communication terminal 200.

As shown in FIG. 6, the camera unit 1 of the imaging module 1 is placed on the outer surface 33 c of the housing 33 a.
a and the infrared thermosensor 3a of the temperature measurement module 3 are arranged adjacent to each other, and the imaging area of the imaging module 1 and the measurement area of the temperature measurement module 3 are configured to overlap.

The portable information communication terminal 200 of this embodiment includes an information communication module 21 and has an information communication function. For this reason, the CPU 7a has both functions of arithmetic processing for imaging and temperature measurement and arithmetic processing for information communication. The CPU 7a is also directly connected to the display unit 5 in order to display character data and the like necessary for information communication. The display unit 5 is shared so as to perform both display for information communication and display for temperature measurement. Also,
The operation unit 31 is configured to perform both key input for information communication and input for imaging and temperature measurement. As described above, the CPU 7a, the display unit 5, and the operation unit 31 are shared by the information communication function and the temperature measurement function, so that the size can be reduced to the same size as an information communication terminal such as a normal mobile phone.

In addition, in the portable information communication terminal 200, a mode switching unit 15 is provided to switch between two modes of a normal shooting mode and a temperature measurement mode in order to capture a visible image and measure temperature.
In the present embodiment, since the configuration other than the above is the same as that of the temperature measurement display device 100 of the first embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.

The portable information communication terminal 200 according to the present embodiment can switch between a normal shooting mode for shooting a visible image and a temperature measurement mode for measuring temperature together with shooting of a visible image. That is, in the normal shooting mode, a visible image can be shot in the same manner as a general camera-equipped mobile phone, and in the temperature measurement mode, it can be used as a non-contact thermometer capable of visually recognizing an image.

Switching operation between the normal photographing mode and the temperature measurement mode can be performed by the operation unit 31. For example, the temperature measurement mode can be turned on by operating the operation unit 31 and selecting “temperature measurement” from the menu screen. A switch unit (not shown) dedicated to mode switching may be provided. When the temperature measurement mode is selected, the setting parameter based on the corresponding control signal is stored in the mode switching unit 15. In the temperature measurement mode, the camera unit 1a of the imaging module 1 and the infrared thermosensor 3a of the temperature measurement module 3a are measured objects.
The temperature measurement is started by pressing the shutter key from a predetermined distance. The function of the shutter key can be assigned to any key of the operation unit 31.

Here, a procedure of photographing and temperature measurement in the portable information communication terminal 200 will be described with reference to FIG. First, in step S1, the shutter key is pressed. In step S2,
The CPU 7a refers to the setting parameter of the mode switching unit 15 and checks whether or not the temperature measurement mode is on. If the temperature measurement mode is on (Yes) in step S2, imaging of the measurement object and temperature measurement are performed in step S3. In other words, the imaging module 1 and the temperature measurement module 3 are operated simultaneously to capture a visible image of the measurement object and measure the temperature. Note that the timing of imaging and temperature measurement does not have to be strictly the same, for example, even if there is a timing error within several seconds.

In step S4, visible image data captured by the imaging module 9 is created in the same manner as in a normal imaging apparatus. In step S5, thermal image data of the surface temperature of the measurement object detected by the infrared thermosensor 3a is created. In this case, analog format temperature data measured by the temperature measurement module 3 is converted into a digital format by an A / D converter (not shown), output to the CPU 7a, and the temperature / temperature stored in the storage unit 13a in the CPU 7a. The color conversion table (not shown), the color data of the three primary colors R, G, and B and the data of the partition line L stored in the graphic memory unit 13b are referred to, and thermal image data corresponding to the measured temperature is created. . In FIG. 7, the thermal image data is created in step S5 after the visible image data is created in step S4. However, the order is not limited, and the thermal image data is created first (in step S4). Next, visible image data may be created (in step S5).

Next, in step S6, the visible image data and the thermal image data created in steps S4 and S5 are combined in the image combining unit 9. That is, the overlay process is performed so that the visible image and the thermal image overlap at the same part of the measurement object.

Next, in step S <b> 7, the image data combined by the image combining unit 9 is output to the data conversion unit 11 and converted into a format that can be displayed on the display unit 5. In step S8, the heat distribution image is displayed on the display 5a of the display unit 5 so as to overlap the visible image. Here, by operating the operation unit 31 and designating an arbitrary section (image region) on the display 5a of the display unit 5, the temperature of the image region can be numerically displayed on the sub window 5b.

The image displayed on the display unit 5 can be recorded in the storage unit 13a as necessary in step S9 or transmitted to a server or the like using a communication function.

On the other hand, when the temperature measurement mode is not on (No) in step S2, since it is the normal shooting mode, shooting is performed by operating only the imaging module 1 in step S10.
Next, visible image data is created in step S10. The visible image data is output to the image composition unit 9 as a digital YUV signal or a digital RGB signal representing the visible image,
Further, the data is output to the data converter 11. Thereafter, similarly to the above, the processes of step S7, step S8, and if necessary, step S9 are performed.

As described above, the portable information communication terminal 200 according to the present embodiment can be switched between the normal shooting mode for shooting a visible image and the temperature measurement mode for measuring the temperature together with the shooting of the visible image with a simple key operation. Since it is configured, information communication, visual image capturing, and temperature measurement can be performed with one compact portable terminal, which is excellent in convenience.

Moreover, since the portable information communication terminal 200 of this Embodiment is provided with the information communication function and the temperature measurement function, after measuring the surface temperature of the specific position of a measurement object, this measurement data is made into arbitrary servers. Since the temperature measurement data can be easily managed by transmitting the data to, etc., it is excellent in convenience.

  Other configurations and effects in the present embodiment are the same as those in the first embodiment.

While the present invention has been described with reference to the embodiment of the present invention, the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, when the measured temperature of the selected area is displayed numerically, the sub window 5b is displayed on the display 5a. However, for example, a second display different from the display 5a is provided. It is also possible to adopt a configuration in which the measured temperature is displayed numerically there.
