     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0018]    The following description is about embodiments of the present invention; however it is not intended to limit the scope of the present invention. 
         [0019]      FIG. 1  shows a block diagram of handset mobile communication device for measuring body temperature. The handset mobile communication device  1  comprises a processor  11 , image capturing module  12 , thermal measuring interface  13 , communication module  14 , and operating module  15 . The image capturing module  12  is configured to acquire an optical image from an external target. The thermal measuring interface  13  is configured to electrically connect with an external thermal imaging sensor  131  which is configured to acquire a thermal image from aforementioned target. The processor  11  further compares and correlates the optical image and the thermal image so as to provide a piece of temperature information of a selected portion of the target. The operating module  15  provides an operating interface which provides user operating the handset mobile communication device  1  of present application. The aforementioned operating interface can be implemented by software interface, hardware interface or touch controlling interface. The aforementioned thermal imaging sensor  131  can be implemented by the semiconductor thermal imaging sensor. The aforementioned image capturing module  12  comprises a camera and a control circuit thereof. The thermal measuring interface  13  comprises wireline connecting interface (e.g. physical plug, conductive line) or wireless connecting interface (e.g. RF communication interface, NFC communication interface). The communication module  14  comprises wireline communication circuit or wireless communication circuit (2G/3G/4G/5G, Wi-Fi, Bluetooth . . . etc.). Present application provides following two body temperature measuring means to achieve aforementioned objective, however the recognition mode is not limited by following description. 
         [0020]    First recognition mode: 
         [0021]    In another one embodiment, processor  11  recognizes the optical image so as to mark the selected portion, and identify the graphic feature of optical image and the thermal image (e.g. recognizing the graphic frame line of optical image and thermal image). Then, the processor  11  overlaps and compares two graphic frame lines which having the same or similar graphic feature to form a correlation. Next, the processor  11  recognizes the selected portion and related temperature information. 
         [0022]    Second recognition mode: 
         [0023]    In another one embodiment, the processor  11  compares and correlates each reference point of optical image and thermal image so as to generate a related correlation between the optical image and the thermal image. Then, the processor  11  recognizes the optical image to identify the selected portion of the target, and accesses temperature information of the selected portion of the thermal image related to the selected portion of the optical image. 
         [0024]    In another embodiment, for quickly recording measured temperature information of the target, processor  11  further recognizes the optical image so as to provide a piece of identification (ID) information. The processor  11  further correlates ID information and temperature information to form a record file. The processor  11  may stores, or transmits this record file. 
         [0025]    In another embodiment, the handset mobile communication device  1  of present application further comprises an alarm unit. The aforementioned alarm unit is connected with processor  11 . The alarm unit further provides a piece of alarm information when temperature information exceeding the default value. The aforementioned alarm unit can be implemented by the software or hardware circuit. 
         [0026]      FIG. 2  shows a flow chart of body temperature measuring method of another one embodiment of present application. The steps of body temperature measuring method are descripted as below: 
         [0027]    S 101 : acquiring an optical image and a thermal image of external target. 
         [0028]    S 102 : comparing optical image and thermal image to mark the selected portion of the target, and providing temperature information. 
         [0029]      FIG. 3  shows an operating schematic diagram of present application. When user operates the handset mobile communication device  1  to shoot the target, then the device  1  acquires an optical image  21  and thermal image  22  of target. The image is displayed on the operating interface  2  of touch screen. The user may set the handset mobile communication device  1  to measure the temperature of selected portion (e.g. temperature of head). 
         [0030]    Please refer to the  FIG. 4 , when user triggers measurement button  230 , it can drives the processor  11  acquiring the image of target  4 . And after triggering image comparison button  232 , the processor  11  may determine the graphic feature (e.g. distribution density of image pixel or image frame line) of two images whether same or similar to each other. Then the processor  11  selectively uses the first recognition mode or second recognition mode to measure the temperature of selected portion so as to provide measurement information. The aforementioned measurement information selectively comprises temperature information  241 , alarm information or time information. 
         [0031]    When the processor  11  determining the graphic feature of optical image and thermal image are same or similar to each other, then selects first recognition mode to identify the optical image  21 . The first recognition mode can identify the selected portion (head) of optical image  21  by imaging recognition technique. Then, the processor  11  recognizes the graphic frame lines ( 212  and  222 ) of aforementioned images ( 21  and  22 ) and executes a similarity comparison. When the two frame line match a similarity determination, the processor  11  overlaps two images ( 21  and  22 ) to acquire the thermal image of head and related temperature information  241 . 
         [0032]    Please refer to the  FIG. 5 , when the target covered shelter (e.g. quilt), because of the processor  11  only acquires parts of thermal image of target  4 , the processor  11  selects the second recognition mode to identify the temperature of head portion. When the processor  11  acquires the optical image  21  and thermal image  22 , the processor  11  can base on the shooting angle or shooting position of the image capturing module  12  and thermal image sensor  13  to mark a reference point of each image (optical image reference point  213  and thermal image reference point  214 ). Next, the processor  11  builds a correlation by overlapping optical image reference point  213  and thermal image referencing point  223 . The processor  11  further recognizes the optical image  21  to identify the selected portion (e.g. head portion) of the target  4  and acquires the selected portion  221  of thermal image  22  by the selected portion  211  of optical image  21  and aforementioned correlation. 
         [0033]    Further explanation, processor  11  takes optical image reference point  213  as origin point(x 0 , y 0 ). After the processor  11  identifies selected portion image from the optical image  21 , then the processor  11  further calculates the correlation coordinate point(x 1 , y 1 ) of selected portion. Next, the processor  11  further takes the thermal image reference point  223  as origin point(x 0 , y 0 ), and acquires the related thermal image  22  and temperature information of the selected portion  221  based on the correlation between (x 0 , y 0 ) and (x 1 , y 1 ). When the processor  11  acquires temperature information of the selected portion  222 , it may selectively operate a connection procedure which identifying the optical image  21  to provide identification (ID) information of target. For example, when the device  1  acquires optical image of patient&#39; head or environment image (e.g. two dimension barcode, ward&#39;s doorplate, hospital bed&#39;s name card, patient&#39;s name card, patient&#39;s barcode bracelet) and identifies the image content to obtain ID information of target. Then processor  11  joints ID information and temperature information together to provide a record file. The format of record file is shown in table 1. User  3  may triggers recording button  233  to enable processor  11  store aforementioned record file, or transmitting the record file to a management device from communication module  14 .
