The electronic device 100 may include an image acquisition module 110, a processor 120, a user input receiving module 130, a display module 140, a communication module 150, and a memory 160. However, the configuration of the electronic device 100 shown in FIG. 2 is only one embodiment of the present invention, and various modifications are possible. For example, the electronic device 100 may further include a user interface for receiving a command or information from a user.

The image acquisition module 110 may acquire a visible image and a thermal image for the object. The object may be the user himself or another. Furthermore, the object is not limited to a person but may be a pet such as a dog or a cat. The visible image is obtained through the image sensor 10 and represents an image photographed through a general camera or a camcorder. Further, the thermal image is acquired through the infrared sensor 20, and can be obtained, for example, by converting the infrared rays detected by the infrared sensor 20 into thermal images at the processor 120.

Processor 120 may execute an application that provides a service based on thermal images to provide the acquired visual and thermal images to a user. The execution of the application may be performed through a user input that is received via the user input receiving module 130 and selects an icon of the application. The operation of acquiring the visible image and the thermal image may be performed based on execution of the application.

The processor 120 may perform calibration on at least one of the obtained visible image and thermal image. For example, the image sensor 10 photographs the entire face of a person, but the infrared sensor 20 is located at the lower part of the human face and the lower part of the face of the person because of the difference in the measurement range or the position of the image sensor 10 and the infrared sensor 20. [ The neck area can be photographed. In this case, the processor 120 may perform the calibration to cause the image sensor 10 and the infrared sensor 20 to photograph the same region. The obtained visible image and thermal image can be displayed on the application through the display module 140. [

According to various embodiments of the present invention, the processor 120 may perform the calibration in a post-processing manner on at least one of the obtained visible and thermal images. For example, when the obtained visible image and thermal image are displayed, the processor 120 may convert at least one or more images so that the positions and sizes of the objects displayed in the visible image and the objects displayed in the thermal image correspond to each other Enlargement, reduction, and the like with respect to the image data. In this case, the display module 140 may display the visible image and the thermal image on which the calibration is performed on the application.

The user input receiving module 130 may receive a user input for setting a maximum temperature and / or a minimum temperature to be displayed through the thermal image. In this case, the processor 120 may perform temperature-based filtering on the thermal image to meet the set temperature. The display module 140 may display the filtered thermal image on the application.

Infrared rays are absorbed by various types of molecular vibrations, so the transmittance differs depending on the state of the path through which infrared rays are transmitted, and materials made of different kinds of atoms can absorb infrared rays. Thus, moisture in the atmosphere can absorb infrared radiation, and if there is a large amount of moisture in the atmosphere, it can affect the acquisition of accurate thermal imaging. To prevent this, the processor 120 may correct the acquired thermal image based on environmental factors (e.g., relative humidity or infrared emissivity) around the electronic device 100. In this case, the relative humidity or the infrared emissivity around the electronic device 100 may be obtained through various sensors provided in the electronic device 100, or may be input from the user through the user input receiving module 130.

The processor 120 may diagnose a health condition of the object based on the thermal image. In this case, the processor 120 may diagnose the health state of the object by considering at least one of the sex, age, height, weight, and medical history of the object.

According to various embodiments of the present invention, the processor 120 may detect an area of the plurality of areas included in the thermal image, which is higher than a predetermined first temperature, or an area that is lower than a predetermined second temperature. For example, if the temperature of some or all of the objects is too high or too low, the processor 120 may determine that the state of the object is bad. In this case, the processor 120 may cause the display module 140 to display an indicator for the detected area. In this case, the first temperature or the second temperature may be set differently for each region of the region. Further, the first temperature or the second temperature may be set differently considering at least one of sex, age, height, body weight, and history of the object.

The processor 120 detects an area of the plurality of areas included in the thermal image, the temperature difference between adjacent areas being equal to or greater than a preset temperature difference, and displays the indicator for the detected area through the display module 140 have.

According to various embodiments of the present invention, the communication module 150 transmits the visible image or the thermal image to the external device 200 and reads the visible image or the thermal image from the external device 200 The result can be received. The readout result of the visible image or the thermal image performed by the external device 200 may be such that the first temperature or the second temperature considers at least one of the sex, age, height, weight, and history of the object Can be set differently.

According to various embodiments of the present invention, the electronic device 100 may not include the infrared sensor 20. In this case, the electronic device 100 can acquire thermographic images from the external infrared device separated from the electronic device 100 through the communication module 150. [

The memory 160 may store instructions for data, e.g., operations performed in the processor 110. For example, The data stored in the memory 160 may also include data to be input and output between the respective components in the electronic device 100 and may be input between the electronic device 100 and components external to the electronic device 100 And output data. For example, the memory 160 may store an executable file (e.g., an apk file) of the diagnostic application based on the thermal image.

The memory 160 may include an internal memory or an external memory. The internal memory can be, for example, a volatile memory (e.g., dynamic RAM, SRAM, or synchronous dynamic RAM (SDRAM)), non-volatile memory (e.g., OTPROM one time programmable ROM), programmable ROM (PROM), erasable and programmable ROM (EPROM), electrically erasable and programmable ROM (EEPROM), mask ROM, flash ROM, flash memory (e.g., NAND flash memory or NOR flash memory, a hard disk drive (HDD), or a solid state drive (SSD). The external memory may include, for example, a flash drive (flash memory), such as a flash drive, for example, a compact flash (CF), a secure digital (SD), a micro-SD, a mini-SD, an extreme digital (xD), a multi-media card (MMC), or a memory stick The external memory may be functionally and / or programmably connected to the electronic device 110 via various interfaces. It can be physically connected.
