These electronic devices may also have various operating systems. For example, an operating system of an electronic device can be driven by various operating systems such as Android, iOS, Windows, Linux, Symbian, Tizen, and Bada . It will be apparent to those skilled in the art that the electronic devices and operating systems according to various embodiments of the present invention are not limited to the examples described above.

1 is an internal block diagram of a smartphone having a digital camera to which the present invention is applied.

The communication module 110 of the smartphone may include an antenna ANT, a wireless unit 101, a modem 102, a microphone MIC, and a speaker SPK. The antenna ANT may be constituted by one antenna for communicating with the mobile communication network or may be a separate antenna for communicating with a network such as Bluetooth or WiFi in addition to the mobile communication network .

The wireless unit 101 is a wireless signal processing unit capable of communicating with a specific wireless network such as a mobile communication network. The wireless unit 101 performs band up-conversion of data to be transmitted for voice and / or data communication to a band used in a corresponding network, And downconverts the signal received from the network. That is, in order to transmit data, the radio unit 101 performs band up conversion of the baseband data to the band of the network, transmits the data to the corresponding network through the antenna ANT, and transmits a radio signal from the corresponding network through the antenna ANT And converts the signal into a baseband signal by down-converting the band.

The modem 102 performs a series of data processing such as modulation, demodulation, encoding, and decoding of the transmitted / received data. 1, the modem 102 may include a vocoder for performing modulation / demodulation and encoding / decoding of a voice signal. The modem 203 receives an electrical voice signal from the microphone (MIC) and converts it into a digital voice signal. Also, the modem 203 can convert the digital voice signal into an analog electric voice signal and output it through the speaker SPK. In addition, the modem 203 processes a series of operations such as modulation, demodulation, coding, and decoding under the control of the control unit 109 in the case of data to be used.

The camera module 120 of the smart phone includes a photographing section 103 and an image processing section 104. [ The photographing unit 103 includes a lens, a motor for driving the lens, a control circuit for driving the motor, and an image sensor for receiving light transmitted through the lens and acquiring brightness and color information of the light by an electrical signal . At this time, since the signal obtained by the sensor is a weak analog signal, the photographing unit 103 may further include an additional circuit for amplifying the sensed signal and converting the sensed signal into a digital signal.

The image processing unit 104 converts the photographed digital signal input from the photographing unit 103 into graphic data that can be processed by the control unit 109 and provides the converted graphic data to the control unit 109. [ Further, various kinds of information of the photographing section 103 are set as additional information (EXIF) and provided to the control section 109. [ Time, exposure mode, exposure time, height of the picture, width of the picture, horizontal resolution, and the like, for example, the auxiliary information provided by the image processing unit 104 to the control unit 109, Vertical resolution, camera model, and the like. The control unit 109 may acquire the additional information in advance without providing the additional information in the image processing unit 104. [ That is, the values set at the time of photographing are acquired in advance.

In addition, the camera module 120 may have two different modules. In other words, in the case of a smartphone, a camera module can be provided in front of and behind the smartphone, respectively. In addition, if the camera is provided on the front side and the rear side of the smart phone, only two photographing units 103 among the camera modules may be provided. In this case, the image processing unit 104 may share one image, and only two image capturing units 103 may be used.

The memory 105 is a storage medium such as a ROM or a RAM and stores various control data required for the operation of the smartphone. And stores control data for obtaining additional information to be inserted and utilization of the obtained additional information. In addition, the memory 105 may have areas for storing additional information of photographed photographs and photographs, as well as areas for storing various user data.

The satellite signal receiving unit 106 receives the signal received from the satellite, extracts information for determining the position of the terminal from the received signal, and provides the extracted information to the control unit 109. For example, when receiving the arrival angle and time delay information received from the satellites, the satellite signal receiving unit 106 extracts the arrival angle and time delay information of the signals received from the respective satellites, and provides the extracted angle and time delay information to the control unit 109.

The display unit 107 is configured in the form of an LCD panel or an LED panel, and controls the operation of the smart terminal and the status of the smart terminal in a waiting state under the control of the controller 204. [

The input unit 108 may include a touch input touch sensor for a user and a key button for inputting a key. The input unit 108 receives a signal or / and a key input signal for the touch input of the user and provides the signal to the control unit 109.

The control unit 109 controls the overall operation of the smartphone and performs control for acquiring additional information to be photographed and added to the photographed photograph according to the present invention. The control operation for the control unit 109 to acquire information to be added to the photographed and photographed photograph according to the present invention will be described with reference to a control flowchart to be described later.

2A to 2D are control flow charts for photographing and acquiring additional information in a smartphone to which the present invention is applied.

The control flowchart of Figs. 2A to 2D is an operation performed in the photographing mode. The photographing mode is a mode in which the smart phone drives the camera module 120 to receive the light amount of light reflected from the subject and convert it into a graphic for providing to the user and display it on the display unit 107 Operation. An example of the form displayed on the display unit 107 in the pre-shooting mode is shown in FIG.

3 is an exemplary view showing an image obtained through the camera module 120 on the display unit 108 in an electronic device having a camera.

The image acquired through the camera module 120 is data displayed on the display unit 108 in a preview format before the image is taken. The image 301 displayed on the lower left portion of the subject to be photographed may be a photograph of the user himself / herself. As another example, the image 301 displayed on the lower left portion of the subject to be photographed may be the image of the photographer obtained from the camera on the opposite side of the lens for photographing the subject, if the subject has two different cameras. That is, if the camera module has two camera modules or two photographing parts, the photographer's photographs can be obtained from different lenses, respectively.

In addition, an icon 303 for selecting recording and shooting, a photographing icon 302, and a recording icon 304 are shown at the right center of the subject to be photographed. That is, reference numerals 301 to 304 may not be photographed images.

The control unit 109 places the standby state of the photographing mode at step 200. [ That is, as described above, the data input from the camera module 120 is displayed on the display unit 107 in order to acquire a graphic to be shot. The control unit 109 proceeds to step 202 in the photographing standby state to check whether there is a user input requesting photographing from the input unit 108. [ If it is determined in step 202 that shooting is requested, that is, if a shooting request signal is received from the input unit 108, the control unit 109 proceeds to step 206.

On the other hand, if it is determined in step 202 that the photographing request signal is not received from the input unit 108, the process proceeds to step 204, where it is checked from the input unit 108 whether an end of the photographing mode is required. If it is determined in step 204 that the photographing is to be ended, the control unit 109 ends the photographing mode. On the other hand, if the photographing end is not requested, the photographing standby state of step 200 is continuously performed.

The step of checking the end request of the photographing mode in step 204 is an operation that may occur in any of the control flowcharts described in the present invention. In FIG. 2A, step 204 is shown as an example after step 202, and may be performed during or after any other operation. If it is required to terminate the photographing mode during or after the operation other than the step 202, the previous operation may be stored in the memory 105 as needed. For example, if the operation is performed after a specific photograph is taken, the photographed photograph may be stored in the memory 105.

On the other hand, when the process proceeds from step 202 to step 206, the control unit 109 acquires the photograph and additional information. The control unit 109 controls the photographing unit 103 of the camera module 120 to acquire analog image data from the input optical signal and converts the digital signal into a digital signal, ). After that, the image processing unit 104 converts the image data converted into the digital signal into graphic data that can be processed by the control unit 109, and provides the graphic data to the control unit 109. At the same time, the control unit 109 acquires the additional information of the photographed photograph. At this time, part or all of the additional information may be obtained from the image processing unit 104 or may be acquired by the control unit 109 itself. In the following description, it is assumed that the control unit 109 acquires all the additional information of the photographed photograph by itself.

As described above, the additional information of the photograph may include a value of a numerical value, a brightness value, a color area, a date, a time, an exposure mode, an exposure time, A location where the photograph was taken, and the like, or other information. It is assumed that the additional information of the photograph described in the present invention includes at least one of the above-described information.

The control unit 109 displays a picture on the display unit 107 in such a form that the user can visually confirm the graphic data acquired from the image processing unit 104 in step 208. [

The controller 103 displays the photo data in step 208 and then checks whether insertion of user data is required in step 210. [ The user additional data means data to be set by the user among the additional data. That is, it is checked whether the addition of the data set by the user among the types of the additional data EXIF described above is required.

One method for determining whether or not to insert user data is to display on the display unit 107 a message inquiring whether the user has set the user data, Or not.

As another method for determining whether or not the user-side data is to be inserted, it may be set to go to the user-side data insertion step each time shooting is performed in the environment setting. In this case, step 210 may be a step of checking whether or not the user-side data is set to be inserted every time the photograph is taken.

As another method for determining whether or not the user-side data is to be inserted, the user may set the user side data insertion in advance when proceeding to the shooting mode. In this case, the step 210 may be a step of checking whether or not the user-side data is set to be inserted in the photographing mode.

In the following description, for convenience of description, a method of determining whether or not to insert user-assigned data will be described on the assumption that the first step is to display the inquiry to the display unit 107 and proceed through user selection.

On the other hand, if it is determined in step 210 that the insertion of the user data is required, the controller 103 proceeds to step 214. If insertion of the user data is not requested, the controller 103 proceeds to step 212, And stores the information in a memory area previously set in the memory 105. [

In the case of proceeding to step 214, the control unit 109 checks whether a map display is requested. If it is determined in step 214 that the map display is requested, the flow advances to step 220. On the other hand, if the map display is not requested,

When a map display is required, it can be checked in the same manner as the above-described inserting of additional user data.

One method for checking whether a display of a map is required is to display on the display unit 107 a message asking the user whether to display the map on the display unit 107, It is possible to judge whether the display of the map is required or not.

As another method for checking whether or not display of a map is required, it may be set to display a map of the position where the current photographing is performed each time photographing is performed in the preference setting. Accordingly, step 214 may be a step of checking whether the map is set to be displayed each time photographing is performed.

As another method for checking whether the display of the map is required, the user may set the display of the map data in advance when proceeding to the shooting mode. In this case, step 210 may be a step of checking whether a preset value is set to display a map each time photographing is performed.

In the following description, for convenience of description, it is assumed that a method of checking whether a map is requested is displayed on the display unit 107, which is the first method, and then proceeds through user selection .

On the other hand, if the process proceeds from step 214 to step 216, it is checked whether re-photographing is required. That is, it is a step to check whether a specific re-photographing is required for inserting data of the user's part. The same test as in steps 210 and 214 may be performed to determine whether a re-photographing operation is required.

If it is determined in step 214 that retaking is required, the control unit 109 proceeds to step 240. If retaking is not requested, the control unit 109 proceeds to step 218. [

First, in step 218, the control unit 109 checks whether a drag operation exists in the photograph from the input unit 108. [ That is, the control unit 109 checks whether a drag input is present from the input unit 108 through a drag operation in a state in which a picture is displayed on the display unit 107. [ If it is determined in step 218 that the drag operation is detected, the controller 109 proceeds to step 260, otherwise proceeds to step 214.

On the other hand, when the flow advances from step 214 to step 220, the control unit 109 displays map data and coordinates on the display unit 107. In order to display the map data and the coordinates, the control unit 109 uses the signal received from the satellite signal receiving unit 106 to acquire the coordinates of the latitude and longitude at which the smartphone is located. In addition, the controller 109 reads the map data of the area including the latitude and longitude coordinates at which the smartphone is located in the memory 105, and displays the map data on the display unit 107 at a preset magnification.

Then, the controller 109 proceeds to step 222 to check whether a specific area of the map data displayed on the display unit 107 is dragged. If the specific area is dragged, the control unit 109 proceeds to step 224. In step 224, An operation in which dragging is performed while map data is displayed on the display unit 107 will be described with reference to FIG. 4A.

4A illustrates an operation for inserting user data in accordance with the present invention in a state in which a map corresponding to a current position is displayed in a smartphone.

In FIG. 4A, the position where the touch is performed at the position where the map data is displayed on the display unit 107 is denoted by reference numeral 401. When the first touch is made, the input unit 108 provides the coordinate value for the touch input to the control unit 109. [ Also, when the dragging is performed in a specific direction, such as the touch reference numeral 402, the input unit 108 detects information on the dragged direction and movement distance, and provides the detected information to the control unit 109. That is, in step 222, the control unit 109 checks whether the touch and drag operations are present from the input unit 108 in the form as shown in FIG. 4A.

The control unit 109 recognizes the characters of the dragged area in step 224. The overall operation of recognizing the characters of the dragged area will be described with reference to FIGS. 4A and 4B.

FIG. 4B is an exemplary view for explaining a case where a character is recognized according to a drag in map data displayed according to the present invention.

As described with reference to FIG. 4A, the control unit 109 can perform matching with the data displayed on the map data by using the touch position information, the direction in which the dragging is performed, and the distance information in the map data displayed on the display unit 107. [ Accordingly, the control unit 109 sets the area where the touching and dragging are performed to the area for character recognition as indicated by reference numeral 410. To be more specific, a rectangle is set to have a length from a start point to an end point of a movement line in which a touch and a drag are made, and a predetermined height and a height. That is, it is set to be a predetermined size corresponding to the input of the user. The area thus set becomes the reference numeral 410.

The control unit 109 can extract characters from the area denoted by reference numeral 410. [ Also, if characters are included in the map data in the form of a picture, the control unit 109 can acquire characters using a method of acquiring characters from the picture.

If the character recognition is performed using the above-described method, the controller 109 proceeds to step 226 and displays the recognized character on the display unit 107. [ The recognized character display can display a separate character display window on the display unit 107 in a manner similar to the case of inputting a text message.

Thereafter, the control unit 109 proceeds to step 228 to check whether the character correction is required. In other words, the control unit 109 checks whether or not there is an input for a character modification request from the input unit 108. [ If the character correction is required, the control unit 109 proceeds to step 230 to display a screen for character correction, and performs character correction on the basis of the signal input from the input unit 108. Here, the display of the screen for character modification displays a cursor and a recognized character. In addition, the cursor can be set in a movable form, and a keyboard for correcting characters can be displayed together. Accordingly, the input unit 108 can correct the acquired character corresponding to the signal input by the user.

When the correction is made and the correction is completed, the control unit 109 inserts the modified data in step 232 into the additional data as user additional data, and stores the additional data and the photographed image data in a predetermined area of the memory 105 .

The photograph data may be a photograph as shown in FIG. 3, and additional data including user additional data may be illustrated as shown in FIG. 4C.

4C is an example of a case where user additional data obtained by the method according to the present invention among additional data of photographs according to the present invention is set.

As shown in FIG. 4C, the additional data may include a width, a height, a horizontal resolution, a vertical resolution, and the like of the acquired image, and particularly includes a user data 420. The data stored in the user side data 420 may be data obtained according to the method of the present invention,

On the other hand, if the control unit 109 proceeds from step 216 to step 240, the control unit 109 maintains a retake standby state. Here, the re-photographing standby state means the same state as the photographing standby state in the above-described 200 step. However, in the retake standby state, the previously captured image information and the additional information are not completely stored, and the remaining state is the same in that the state is temporarily stored to acquire the additional information.

FIG. 5A is a diagram illustrating an example of a retake standby state in which a retake is performed according to an embodiment of the present invention. FIG.

5A, the images acquired by the photographing unit 103 and the image processing unit 104 are provided to the control unit 109, and the control unit 109 displays the images on the display unit 107. In this case, That is, the re-photographing standby state is displayed in the same manner as in the case of FIG. 3 described above.

Thereafter, the control unit 109 checks in step 242 whether the photographing is required. If it is determined in step 242 that shooting is desired, the control unit 109 proceeds to step 244, and if not, proceeds to step 240.

When the photographing is requested and the process proceeds to step 244, the control unit 109 acquires image data through photographing as in step 206. [ That is, the image data received from the camera module 120 is received. At this time, the additional information as described above may be acquired or not acquired when acquiring the image information. The additional information may not be needed because the image acquired in order to insert the additional information of the previously photographed information in the information obtained through the re-photographing.

The control unit 109 converts the acquired photograph into a form that can be visually confirmed by the user and displays it on the display unit 107. [ In step 246, the control unit 109 checks whether there is a drag in the specific area while displaying the re-photographed image. In step 246, dragging of a specific area is performed by touching and moving after touching one point as described above. This will be described with reference to FIG. 5B.

FIG. 5B is a diagram for explaining a process for acquiring user-attached data in a photograph taken again according to an embodiment of the present invention.

As shown in FIG. 5B, a state in which the touch point 501 where the touch is performed and the post-touch movement 502 are indicated by arrows. If the touch and drag operations are performed after the photograph is photographed, the area of the corresponding point can be set corresponding to the movement path from the touch point to the end point of the drag.

Accordingly, the control unit 109 proceeds to step 248 to set the dragged area, recognize the character in the set area, and display the recognized character on the display unit 107. [ The operation of setting the dragged area is the same as that of step 224 described above.

FIG. 5C is a diagram illustrating a character extraction area in a photograph taken again according to an embodiment of the present invention.

That is, as shown in FIG. 5C, the character extraction area 510 is set to have a constant height from the touch point to the point where the drag is performed in the re-photographed photograph. That is, the character extraction area 510 is set to have a predetermined size corresponding to the input of the user. Thereafter, the control unit 109 extracts characters from the character extraction area 510. In the operation 226 for extracting a character from the character extraction area 510, the character can be recognized through the same operation as the method for recognizing the character in the map set as the photograph in step 226. [

The control unit 109 proceeds to step 250 to check whether a character is required to be corrected. In other words, the control unit 109 checks whether or not there is an input for a character modification request from the input unit 108. [ If the character correction is required, the control unit 109 proceeds to step 252 to display a character correction screen on the display unit 107, and performs character correction based on the signal input from the input unit 108. [ Here, the display of the screen for character modification displays a cursor and a recognized character. In addition, the cursor can be set in a movable form, and a keyboard for correcting characters can be displayed together. Accordingly, the input unit 108 can correct the acquired character corresponding to the signal input by the user.

When the modification is completed and the modification is completed, the controller 109 inserts the modified data in step 254 into the additional data as the additional data, and stores the additional data and the photographed photographic data in a predetermined area of the memory 105 .

Here, the picture data may be a picture as shown in FIG. 3, and the additional data including user additional data may be stored as shown in FIG.

On the other hand, in the case of proceeding from step 218 to step 260, the control unit 109 sets the first photographed picture, that is, the area dragged from the picture as shown in FIG. 3, recognizes the character in the set area, And displays it on the display unit 107.

This will be described with reference to FIG. 6 is an exemplary diagram for setting user additional information of a photograph using a photograph originally photographed.

As shown in Fig. 6, the direction and distance in which the dragging is performed from the touch point 601 where the touch is made in the photographed picture is indicated by the arrow 602. [ After touching and dragging are performed, the controller 109 proceeds to step 260, sets the dragged area, recognizes the character in the set area, and displays the recognized character on the display unit 107. The operation of setting the dragged area is the same as that of step 224 described above. That is, as shown in FIG. 6, the character extraction area is set so that the size of the re-photographed image is constant from the touch point to the dragged point. Thereafter, the control unit 109 extracts characters from the character extraction area. In the operation 226 for extracting a character from the character extraction area 510, the character can be recognized through the same operation as the method for recognizing the character in the map set as the photograph in step 226. [

The control unit 109 proceeds to step 262 to check whether the character is required to be corrected. In other words, the control unit 109 checks whether or not there is an input for a character modification request from the input unit 108. [ If the character correction is required, the control unit 109 proceeds to step 264 to display a screen for character correction on the display unit 107, and performs character correction on the basis of a signal input from the input unit 108. Here, the display of the screen for character modification displays a cursor and a recognized character. In addition, the cursor can be set in a movable form, and a keyboard for correcting characters can be displayed together. Accordingly, the input unit 108 can correct the acquired character corresponding to the signal input by the user.

When the correction is completed and the correction is completed, the control unit 109 inserts the modified data in step 266 into the additional data as user additional data, and stores the additional data and the photographed image data in a predetermined area of the memory 105 .

Here, the additional data including user additional data can be stored as shown in FIG.

FIGS. 7A to 7C are views illustrating a case where a photograph is displayed using user-assigned data set according to the present invention.

FIG. 7A illustrates a case in which a map is displayed together with information on longitude and latitude in which additional information is photographed when displaying photographed photographs. Acquiring map information of longitude and latitude in which photographing is performed among the additional information (EXIF) stored together with the photograph, acquiring map data including points of longitude and latitude from a map previously stored in the memory 105, 110 to acquire map data including a point of longitude and latitude of the additional information from a predetermined network and display the map data together with the photograph information on the display unit 107. [ At this time, the display position such as the reference numeral 701 can be arbitrarily changed by the user.

FIG. 7B is a diagram illustrating a case in which the user additional information acquired through FIGS. 2A to 2D is displayed by using as an optimistic view. FIG. In FIG. 7B, the user information obtained through the above-described method among the additional information is arranged in a photograph in an optimized format and displayed. At this time, the position of the character to be displayed in an optimizing format can be arbitrarily changed by the user. That is, the one shown in FIG. 7B is an example, and the additional information of the user may be located anywhere when the additional information of the user is displayed together. That is, the display position such as the reference numeral 702 can be arbitrarily changed by the user. You can also change fonts, etc.

FIG. 7C is a diagram illustrating a case where user additional information acquired through FIGS. 2A to 2D is displayed as a photo note. That is, in general, when printing a photograph, it is possible to record the travel information or the contents to be recorded on the back of the printed photograph, in the case of setting such information in a photograph taken with a digital camera. Therefore, only a photograph itself is displayed in the case of a general view of a photograph, and display is performed in a form as shown in FIG. 7c only when a photo note, a rear view, or a user side view together is required. The notation position of the photo-note format, such as 703 in FIG. 7C, can change the position or change the font or the like according to the convenience of the user.

As described above, the user additional information can be obtained more easily from the photographs taken using the digital camera, and can be utilized in various forms using the obtained additional information, so that the convenience of the user can be increased in the case of the digital camera to which the present invention is applied .
