Description

  The present invention relates to a portable information terminal, and more particularly to an improvement of a portable information terminal that repeatedly obtains a preview image from a camera that captures a subject and displays the preview image on a display device.

  Many mobile phones are equipped with a camera for photographing a subject. Such a mobile phone repeatedly obtains a preview image from the camera and displays it on the display device. If there is a capture instruction by a user operation, the mobile phone acquires a storage image from the camera and stores it in the memory. Normally, display of a preview image can be started by pressing a specific operation key.

  However, a mobile phone equipped with a touch panel that detects a touch operation does not perform a series of operations of operating a menu key to display a menu screen and selecting an icon for starting the camera by touch operation. There are many things that cannot activate the camera function. In other words, this type of portable information terminal has a problem that the camera function cannot be validated unless a complicated operation procedure is followed, which is inconvenient.

  Therefore, portable terminals that detect the tilt of the terminal device and enable the camera function have been proposed (for example, Patent Documents 1 and 2). In addition, when the relative position state of the display housing and the operation housing and the position information indicating the current position are detected and the display housing and the operation housing are in the unfolded state, the current position is frequently used by the camera. If it is a place, the portable electronic device which validates a camera function is proposed (for example, patent documents 3). In the portable electronic device described in Patent Document 3, position information such as a leisure resort or a sightseeing spot is stored in advance as a place where the camera is frequently used.

  However, in the conventional portable terminal that detects the tilt of the terminal device and validates the camera function, the camera is activated when the terminal device is in a specific posture, and thus the camera is activated against the user's intention. There were many problems. Moreover, even in conventional portable electronic devices that enable the camera function by detecting the relative position state and position information of the display housing and the operation housing, if the housing is deployed in a place where the camera is frequently used, the camera This causes the camera to be erroneously started.

  The present invention has been made in view of the above circumstances, and is capable of enabling a camera function by a simple and intuitive operation while suppressing activation of a camera against a user's intention. The purpose is to provide. In particular, it is an object of the present invention to provide a portable information terminal capable of enabling a camera function only by performing an operation for holding a camera.

  The portable information terminal according to the present invention includes a camera that captures a subject, preview means that repeatedly obtains a preview image from the camera and displays the preview image on a display device, and the camera based on a capture instruction during display of the preview image.

Embodiment 1 FIG.
<Portable information terminal 1>
FIG. 1 is a perspective view showing an example of the configuration of a portable information terminal 1 according to Embodiment 1 of the present invention. FIG. 1 (a) shows the front surface of a terminal housing 10, and FIG. Shows the back side. This mobile information terminal 1 is a mobile phone that can make a call using a mobile communication network. A touch panel 11, a receiving speaker 12, a transmitting microphone 13 and an operation are provided on the front surface of a terminal housing 10. Keys 14 a to 14 c are provided, and a camera 15 is provided on the back of the terminal housing 10.

  The terminal housing 10 has a thin and vertically long rectangular parallelepiped shape. The speaker 12 is disposed at one end of the terminal housing 10 in the longitudinal direction, and the microphone 13 and the operation keys 14a to 14c are disposed at the other end.

  The touch panel 11 includes a display device having a display screen and an operation input device that detects a touch operation on the display screen. For example, a liquid crystal display is used for the display device, and a capacitive sensor is used for the operation input device. The speaker 12 is a sound output device for outputting a received sound. The microphone 13 is a voice input device for inputting a transmission sound. The operation keys 14a to 14c are physical keys to which various functions are assigned in advance, and the assigned function is executed by a user's pressing operation.

  For example, the operation key 14a is a return key for returning to the previous screen. The operation key 14b is a home key for displaying a home screen. The operation key 14c is a menu key for displaying a menu screen.

  The camera 15 is a photographing device that photographs a subject, and a light-receiving lens that forms an image of light from the subject on an image sensor, and an image that generates a video signal by converting the light into an electrical signal corresponding to the amount of received light. It is composed of elements. For example, a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor) image sensor is used as the imaging device.

  In the portable information terminal 1, the camera function can be validated by operating the operation key 14c to display a menu screen and selecting a predetermined camera icon by a touch operation. When the camera is activated, a preview image is acquired from the camera 15 and displayed on the touch panel 11. The user can adjust the composition while viewing the preview image and input a capture instruction by a predetermined touch operation, thereby acquiring a storage image from the camera 15 and storing it in the memory.

  FIG. 2 is a block diagram showing an example of a functional configuration in the portable information terminal 1 of FIG. The portable information terminal 1 includes a touch panel 11, a speaker 12, a microphone 13, a camera 15, a main control unit 20, a wireless communication unit 21, an operation unit 22, an attitude detection unit 23, a current position acquisition unit 24, a display control unit 25, an audio A processing unit 26 and a memory 27 are included.

  The main control unit 20 includes a predetermined processor and performs call processing and shooting control of the camera 15. The wireless communication unit 21 is a transmission / reception unit for communicating with an external device via a cellular base station or a wireless base station, and performing a call or communication with a communication partner. The operation unit 22 receives a touch operation on the touch panel 11 or a pressing operation of the operation keys 14 a to 14 c, generates an operation signal, and outputs the operation signal to the main control unit 20.

  The display control unit 25 controls the touch panel 11 to display a home screen, a menu screen, and the like. The audio processing unit 26 amplifies the audio signal collected by the microphone 13, converts it into digital data and outputs it to the main control unit 20, while converting the audio data output from the main control unit 20 into an analog signal. Drive signal is generated and output to the speaker 12.

  The memory 27 holds a control program of the main control unit 20 and image data taken by the camera 15. As the memory 27, a volatile RAM, a nonvolatile ROM, a semiconductor storage element such as a flash memory, or a magnetic storage device such as an HDD (Hard Disk Drive) is used.

  The posture detection unit 23 is a detection device that detects the terminal posture based on the inclination of the portable information terminal 1 and outputs the detection result to the main control unit 20, and determines whether the terminal posture is in the photographing posture. Used to do. For example, the posture detection unit 23 includes a capacitance type acceleration sensor that detects a change in the position of the movable unit based on a change in capacitance, and is based on the magnitude, direction, and change amount of acceleration per unit time. The rotation angle of the portable information terminal 1 with respect to the reference posture is detected. This posture detection unit 23 operates constantly and repeatedly detects the terminal posture at regular time intervals.

  The terminal posture may be detected using a geomagnetic sensor for detecting geomagnetism, a gyro sensor for detecting angular velocity, an electronic compass, or a combination of these various sensors instead of the acceleration sensor. .

  The current position acquisition unit 24 acquires position information indicating the current position. For example, the current position acquisition unit 24 is based on a GPS receiver that receives a positioning signal transmitted from a GPS (Global Positioning System) satellite and a positioning signal received from a plurality of GPS satellites. And a calculation circuit that outputs the obtained position information to the main control unit 20.

  For the detection of the current position, instead of using the GPS method, the position information of the cellular base station is acquired from the received signal of the wireless communication unit 21 and the current position is obtained using this position information, or WiFi (Wireless Fidelity) It may be configured to use a service that acquires location information by using a combination of these methods.

  In this portable information terminal 1, the terminal attitude detection result is used to enable the camera function only by performing an operation for holding the camera 15. In addition, the detection result of the current position is used in order to suppress activation of the camera 15 against the user's intention.

  FIG. 3 is a perspective view showing an example of the operation of the portable information terminal 1 of FIG. 1, and (a) in the figure shows the terminal posture in a state where the terminal housing 10 is set up in the vertical direction, (B) shows a photographing posture in a state where the terminal housing 10 is tilted in the horizontal direction. In this figure, the horizontal direction parallel to the back surface of the terminal housing 10 is the x-axis direction, the vertical direction is the y-axis direction, and the shooting axis direction perpendicular to the back surface of the terminal housing 10 is the z-axis direction.

  In a state where the terminal housing 10 is set up in the vertical direction, the longitudinal direction of the terminal housing 10 coincides with the y-axis direction. The imaging axis of the camera 15 is the light receiving axis of the light receiving lens, and faces the horizontal direction perpendicular to the back surface of the terminal housing 10. In this state, the camera 15 can be activated to take a picture, but the preview image and the storage image are in a vertically long state in the standing posture of the terminal. Therefore, normally, at the time of shooting, the terminal housing 10 is rotated about the z axis, or is rotated about the x axis, so that the terminal housing 10 is shifted to the horizontal state.

  In a state where the terminal housing 10 is tilted in the horizontal direction (x-axis direction), the longitudinal direction of the terminal housing 10 coincides with the x-axis direction. In the portable information terminal 1, such a terminal posture is called a photographing posture, and the camera 15 can be activated by a simple and intuitive operation of bringing the terminal posture close to the photographing posture.

  A rotation operation of the terminal housing 10 around the x, y, and z axes is detected by the attitude detection unit 23. Further, whether or not the user holds the terminal housing 10 in such a posture as to hold the camera 15 is determined by comparing the terminal posture with the photographing posture. Specifically, the terminal posture when the inclination of the terminal housing 10 around the x and z axes is within a predetermined range with the horizontal plane as a reference is regarded as the photographing posture, and such a photographing posture is determined for a certain time T. Maintaining the above is the activation condition of the camera 15. For example, T = 1 to about 2 seconds.

<Main control unit 20>
FIG. 4 is a block diagram illustrating a configuration example of the main control unit 20 of FIG. The main control unit 20 includes a destination designation unit 101, a schedule management unit 102, a calendar information storage unit 103, a destination position registration unit 104, a route guidance unit 105, a shooting position storage unit 106, a position comparison unit 107, and a shooting posture storage unit 108. , A posture comparison unit 109, a preview unit 110, and an image capture unit 111.

  The preview unit 110 repeatedly acquires a preview image from the camera 15 and generates screen data to be displayed on the touch panel 11. The preview image is a captured image for display. By repeatedly acquiring and displaying the image on a display device, the subject being captured can be confirmed by a moving image.

  The image capture unit 111 acquires a storage image from the camera 15 based on the capture instruction during display of the preview image, and stores it in the memory 27. The storage image is a captured image having a larger number of pixels and higher resolution than the preview image. This storage image is stored in the memory 27 as compressed data obtained by compressing the data amount in a predetermined format.

  The target position registration unit 104 designates a target position based on a user operation and outputs position information indicating the target position to the route guide unit 105. The route guidance unit 105 obtains a movement route between the current position acquired by the current position acquisition unit 24 and the target position specified by the target position registration unit 104, and generates screen data to be displayed on the touch panel 11. And guide the route. A route guidance function is realized by these configurations.

  The movement path between the current position and the target position is displayed in association with the guidance map. The map data for guidance is stored in advance or downloaded from a server device on a communication network such as the Internet. In the shooting position storage unit 106, the target position designated by the target position registration unit 104 is stored as a shooting position.

  The destination designation unit 101 designates a destination based on a user operation, and outputs destination information indicating the destination to the schedule management unit 102. The schedule management unit 102 is a calendar information generating unit that generates calendar information in which a destination is associated with a date and time. The calendar information storage unit 103 holds calendar information in which the destination specified by the destination specifying unit 101, the message specified by the user, and the date and time are associated with each other. In the requirement, the contents and purpose of the event or business are retained. With these configurations, a schedule management function is realized.

  Based on the calendar information generated by the schedule management unit 102, the route guide unit 105 sets the destination corresponding to the current date as the target position, and sets the destination corresponding to the immediately preceding date and time as the starting position. Find the travel route. In the photographing position storage unit 106, a destination corresponding to the current date is held as a photographing position.

  The user can arbitrarily select whether the target position registered using the route guidance function is used as the shooting position or the destination registered using the schedule management function is used as the shooting position.

  The position comparison unit 107 compares the current position acquired by the current position acquisition unit 24 with the destination registered with the route guidance function and the pre-registered shooting position, and outputs the comparison result to the preview unit 110. The shooting posture storage unit 108 holds posture information indicating a predetermined shooting posture. Posture comparison unit 109 compares the terminal posture detected by posture detection unit 23 with the shooting posture, and outputs the comparison result to preview unit 110.

  The preview unit 110 starts displaying a preview image based on the comparison results of the posture comparison unit 109 and the position comparison unit 107. For example, if the route guidance function is in use or there is a previous usage history, the preview is displayed if the current position is in the vicinity of the shooting position and the terminal posture matches the shooting posture within a predetermined range. Start displaying images.

  Steps S101 to S107 in FIG. 5 are flowcharts showing an example of the operation in the main control unit 20 in FIG. First, the main control unit 20 confirms the terminal posture (step S101), and confirms the use state of the route guidance function if it matches the shooting posture within a certain range (steps S102 and S103). At this time, if the route guidance function is not used, the main control unit 20 immediately ends this processing (step S104). On the other hand, when using the route guidance function, the main control unit 20 acquires the current position via the current position acquisition unit 24 (steps S104 and S105), and compares it with a pre-registered target position ( Step S106).

  If the current position is not near the target position, the main control unit 20 ends this process. On the other hand, when the current position is near the target position, the main control unit 20 activates the camera 15 and starts displaying a preview image (step S107).

  According to the present embodiment, since the display of the preview image is started according to the comparison result of the terminal posture and the shooting posture and the comparison result of the current position and the shooting position, the preview can be performed without following a complicated operation procedure. Image display can be started. For example, if the current position is in the vicinity of the photographing position registered as the target position for route guidance, the change of the terminal posture is detected from the change of the tilt by setting the portable information terminal 1 to the photographing posture, and the preview image is displayed. The display can be started. That is, the camera function can be validated simply by performing an operation for holding the camera 15.

  In addition, since the display of the preview image is started by comparing the target position arbitrarily designated by the user with the current position, it is possible to prevent the camera 15 from being activated against the user's intention.

Embodiment 2. FIG.
In the first embodiment, the example in which the target position registered using the route guidance function is used as the shooting position has been described. In contrast, in the present embodiment, a case will be described in which a destination registered using the schedule management function is used as a shooting position.

  Steps S201 to S208 in FIG. 6 are flowcharts showing a configuration example of the portable information terminal 1 according to the second embodiment of the present invention, and an example of the operation of the main control unit 20 is shown. First, the main control unit 20 checks the terminal posture (step S201), and if it matches the shooting posture within a certain range, checks the calendar information (steps S202 and S203).

  At this time, the main control unit 20 immediately ends this process if the destination and business are not registered with the current date in the calendar information (steps S204 and S205). On the other hand, when the destination is registered in association with the current date, the main control unit 20 acquires the current position via the current position acquisition unit 24 (steps S205 and S206) and compares it with the destination (step S205). S207).

  Here, the destination information indicating the destination is assumed to be converted into position data in advance. For example, an address and facility name designated as a destination are converted into corresponding position data. Such conversion processing into position data is performed using a route guidance function, or is performed by downloading position data from a server device on a communication network such as the Internet. For example, the conversion process of the destination information into the position data is executed when the destination is registered.

  If the current position is not near the destination, the main control unit 20 ends this process. On the other hand, when the current position is near the destination, the main control unit 20 activates the camera 15 and starts displaying the preview image (step S208).

  According to the present embodiment, if the current position is near the photographing position registered as the destination in the calendar information, the display of the preview image can be started by bringing the terminal posture closer to the photographing posture. Since the display of the preview image is started by comparing the destination arbitrarily designated by the user with the current position, it is possible to prevent the camera 15 from being activated against the user's intention.

Embodiment 3 FIG.
In the second embodiment, the example in which the destination corresponding to the current date registered using the schedule management function is used as the shooting position has been described. On the other hand, in the present embodiment, the camera function depends on whether or not there is a current position in the vicinity of the moving route having the destination corresponding to the current date as the target position and the destination corresponding to the immediately preceding date and time as the departure position. The case of enabling the will be described.

  Steps S301 to S312 in FIG. 7 are flowcharts showing a configuration example of the portable information terminal 1 according to the third embodiment of the present invention, and an example of the operation of the main control unit 20 is shown. First, the main control unit 20 checks the terminal posture (step S301), and if it matches the shooting posture within a certain range, checks the calendar information (steps S302 and S303).

  At this time, the main control unit 20 immediately terminates this process if the destination and business are not registered with the current date in the calendar information (steps S304 and S305). When the destination is registered in association with the current date, the main control unit 20 confirms whether the destination and the business are registered at the immediately preceding date (steps S305 and S306), and the destination is registered. If so, the destination corresponding to the date and time immediately before is set as the departure place (step S307).

  On the other hand, if the destination is not registered at the immediately preceding date and time, the main control unit 20 sets the terminal position when the destination corresponding to the current date is registered as the departure place (step S312). The main control unit 20 calculates a travel route connecting the departure point and the destination with the destination corresponding to the current date as the destination (step S308). The process for obtaining the travel route between the departure place and the destination may be performed when the destination is registered.

  Next, the main control unit 20 acquires the current position via the current position acquisition unit 24 and compares it with the movement route (steps S309 and S310). At this time, the main control unit 20 ends this process if the current position is not near the movement route. On the other hand, when the current position is near the movement path, the main control unit 20 activates the camera 15 and starts displaying a preview image (step S311).

  According to the present embodiment, if the current position is in the vicinity of a movement route connecting destinations registered in the calendar information, display of the preview image can be started by bringing the terminal posture closer to the photographing posture.

  In the first to third embodiments, the example in which the posture detection unit 23 repeatedly detects the terminal posture at regular time intervals has been described. However, the present invention limits the timing for detecting the terminal posture to this. is not. For example, the configuration may be such that the detection of the terminal posture is started at the timing when the operation key 14a to 14c is pressed or touched. Further, a configuration in which a proximity sensor is provided to detect that the terminal housing 10 has been taken out from the bag or pocket and start detecting the terminal posture is also conceivable. Further, a configuration is also conceivable in which the current position acquisition unit 24 is always operated, the detection of the terminal posture is started by detecting that the user has stopped from the detection result of the current position.

  In the first to third embodiments, the example in which the preview unit 110 starts displaying the preview image based on the comparison results of the posture comparison unit 109 and the position comparison unit 107 has been described. The 15 activation conditions are not limited to this. For example, if it is detected from the detection result of the current position by the current position acquisition unit 24 that the user is moving, the camera 15 is not activated, and if it is detected that the user has stopped, the preview image is displayed. It may be configured to start.

  In the second and third embodiments, the example in which the camera function is enabled according to whether or not the current position is near the destination registered using the schedule management function has been described. The activation conditions of the camera 15 are not limited to this. For example, it is conceivable to prevent erroneous start of the camera 15 by excluding the start of the camera 15 when the destination is divided and registered into a plurality of types and the destination belongs to a specific type. Specifically, if the destination is a public facility such as a city hall, police station, or movie theater, the camera 15 is not activated even if the current position is near the destination. Further, if the character string registered as the message is a specific character string, for example, if the character string indicating the message is “business trip”, “meeting”, etc., the camera 15 is moved even if the current position is near the destination. Do not start.
