1 is a block diagram of a portable terminal having an automatic photographing mode according to the present invention.

1, a portable terminal 100 according to an exemplary embodiment of the present invention includes a camera 110, a sensor unit 120, a position information module 130, an automatic mode setting unit 140, a control unit 150, and a memory 160, as shown in FIG.

In the present invention, a portable terminal means any home appliance that can be carried by a user and has a function of transmitting data to another device. For example, the portable terminal may be a cellular phone, a smart phone, a personal digital assistant (PDA), an iPad, or an electronic dictionary.

The camera 110 processes image frames such as still images or moving images obtained by the image sensor in the video communication mode or the photographing mode. Then, the processed image frame can be displayed on the display. The image frame processed by the camera 110 may be stored in the memory 160 or transmitted externally via wireless communication. The camera 110 may be equipped with two or more cameras according to the configuration of the terminal.

The sensor unit 120 includes at least one of a geomagnetic sensor, a gyro sensor, and an acceleration sensor, and calculates the distance traveled by using the sensors.

Geomagnetic sensors detect the azimuth using the geomagnetic field and detect the north, south, east and west. In the geomagnetic sensor, there are three sensors in the X, Y, and Z directions that can measure the strength of the magnetic field, and the direction of the magnetic field applied to the sensor is measured by the output vector sum of the three sensors.

The gyro sensor detects the direction of the pedestrian. It serves to sense the direction of the angle of the object in units of time based on one axis. The gyro sensor is a sensor that detects the angular velocity and measures how much the angle moves in 1 second. When an object moves, the force of the Coriolis is generated. Using the formula for this Coriolis force, the angular velocity acting on the inertial system is detected. In general, MEMS (Micro Electro Mechanical System) gyro can be used at 1deg / hr level if its accuracy is 10 ~ 100 deg / hr and sensor signal processing is good. When there is no input, it means that the posture changes by 1 degree for 1 hour. A gyro sensor needs to be very precise to calculate the correct posture. The accelerometer sensor is basically used as a sensor to compensate the gyro.

The acceleration sensor detects the movement by calculating the rate of increase / decrease of the speed with respect to the linear motion in the specific direction. The acceleration sensor outputs the magnitude of the acceleration applied to the object. The three-axis acceleration sensor having the three-axis range can measure the acceleration in the three-dimensional space of the three axes of the x, y, and z axes. That is, the motion of the object can be detected from the inclined angle of the object and the acceleration in each direction on the basis of the gravitational acceleration. The tilted angle of the object with respect to the gravitational acceleration is 1 G when the gravitational acceleration is 1 G in the vertical direction and 90 degrees in response to gravity when the horizontal acceleration sensor is tilted. Therefore, the gravitational acceleration is sin (tilted angle), so that it is possible to sense the tilted state and the ground direction.

The position information module 130 is a module for confirming or obtaining the position of the portable terminal. One example is the GPS (Global Position System) module. The GPS module receives position information from a plurality of satellites. Here, the location information may include coordinate information indicated by latitude and longitude. For example, the GPS module can accurately calculate the current location according to the triangulation method by measuring the precise time and distance from three or more satellites and measuring three different distances. A method of obtaining distance and time information from three satellites and correcting the error by one satellite may be used. In particular, the GPS module can acquire latitude, longitude and altitude as well as three-dimensional velocity information and accurate time from the position information received from the satellite.

The automatic mode setting unit 140 can set the conditions on a time basis, such as a time period, a predetermined time interval, and the like, and can set the conditions based on distance, such as a specific location, a certain distance, For example, a periodic condition is set every 10 minutes or every 5 minutes, or every 1 kilometer or every 500 meters. However, when the photographing is set to be performed at a specific time or at a specific position, the specific condition is set. It is possible to set the automatic mode by properly combining the periodic condition and the specific condition.

The control unit 150 plays a role of executing a program for realizing the automatic photographing mode according to the present invention stored in the memory 160. [ That is, the control unit 150 controls the camera 110, the sensor unit 120, the position information module 130, the automatic mode setting unit 140, and the memory 160. When the automatic mode setting unit 140 determines the shooting conditions, the control unit 150 receives the shooting conditions and determines whether the shooting conditions are based on a time reference or a distance. The control unit 130 controls the camera 110 according to the time information received from the position information module 130 to capture an image frame and receives the distance information inputted from the sensor unit 120 when the distance is the reference, And controls the camera 110 according to the distance to pick up an image frame. The captured image frame is stored in the memory 160 together with the positional information and the time information received from the positional information module 130 and the icon of the photograph photographed in the map data stored in the memory 160 matching the positional information Is marked. When the icon is clicked, a matching picture is displayed using the positional information of the map data.

The memory 160 stores still images, position information, and time information captured by the camera 110. [ In addition, a program and map data for implementing the automatic photographing mode according to the present invention may be stored in the memory 160. The memory 160 may be any data storage means such as RAM, ROM, EEPROM, SDRAM, hard disk, and the like.

2 is a flowchart showing each step of a method of storing an image frame by the automatic photographing mode according to an embodiment of the present invention.

The automatic mode setting unit 140 receives the shooting conditions from the user (S201). The photographing condition may be a time reference such as a time period, a predetermined time interval, or the like, or a distance standard such as a specific position, a predetermined distance, and the like.

The controller 150 receives current position information and time information from the position information module 130 (S202), and receives movement distance information from the sensor unit 120 (S203).

The control unit 150 receives the photographing condition from the automatic setting unit and determines whether the photographing condition is based on a time reference or a distance. In case of the time reference, the time information received from the position information module 130 is read and the camera 110 is controlled at a time corresponding to the photographing condition on the basis of the read time information. When the distance information is received, the distance information inputted from the sensor unit 120 is received. When the distance information reaches a position corresponding to the photographing condition on the basis of the distance information, the camera 110 is controlled to photograph the image frame (S204).

When photographing is performed, the control unit 150 arranges the image frame according to the received location information and time information, and stores the image frame in the memory 160 (S205). The control unit 150 marks icons of photographed pictures on map data matching the positional information (S206). When the icon is clicked on the map data, the controller 150 reads out the position information of the icon and displays the image frame having the matching position information in the memory 160.
