Description

  The present invention relates to a technique for performing data communication, particularly data transmission / reception by proximity wireless communication, with a simple operation.

  2. Description of the Related Art In recent years, a system using proximity wireless communication that performs communication within a communicable range of several centimeters to several tens of centimeters using an induced electric field has been developed. It has a high transfer rate and is dedicated to a short distance and is unlikely to affect other wireless systems, making it suitable for data communications that eliminate the need for cable connections between devices.

  For example, there is known a technique for wirelessly transmitting information in a card to a communication target device when a card with a built-in antenna is brought close to the communication target device (Patent Document 1).

In addition, not only a card but also a technology for performing data communication when a communication terminal such as a mobile phone is brought close to other devices is known.
Japanese Patent Laid-Open No. 07-141537

  However, the conventional operation in proximity wireless communication is mainly a simple operation of moving closer to or away from the communication partner, and it is difficult to perform detailed operations such as selection of a communication method.

  In order to solve the above-described problem, the communication device according to the present invention establishes communication without contacting the external device by transmitting the data stored in the storage medium by being close to the external device at a predetermined distance. Close proximity wireless communication means, and setting means for setting data to be transmitted by the close proximity wireless communication means among data stored in the storage medium, and the external device by the close proximity wireless communication means In the case of short-time communication in which the time during which communication is performed is shorter than a predetermined time, the setting means sets the transmission data, and the time during which communication with the external device is performed by the proximity wireless communication means In the case of long-time communication longer than a predetermined time, the close proximity wireless transfer means transmits the data set as the transmission data by the setting means to the external device. That.

  According to the present invention, since the user does not need a complicated operation for the device when instructing the device to perform various processes, the operability of the user can be improved.

<First Embodiment>
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing an example of an internal configuration of a communication apparatus according to an embodiment of the present invention. Examples of the communication device include a digital camera and a digital video camera provided with an imaging unit. Furthermore, a digital TV, a mobile phone, an image viewer, or the like can be used.

  The operation unit 101 is for accepting an operation from a user. As the operation unit 101, for example, various buttons and levers, so-called rotating members called wheels, touch sensors, and the like can be used.

  The microcomputer 102 controls the entire communication apparatus 100 based on signals or programs input from each unit. Note that the control may be executed by a single piece of hardware, or a plurality of pieces of hardware may be configured to function as a single control unit while sharing processing.

  The memory card 103 is a storage medium for storing data. In this embodiment, the memory card 103 can store still image data and moving image data.

  The memory card I / F 104 includes a connector for connecting to the memory card 103 and is an interface for transmitting and receiving data between the memory card 103 and the communication device 100.

  In this embodiment, the memory card 103 can be attached to and detached from the communication device 100 via the memory card I / F 104. However, the communication device 100 may incorporate a storage medium such as a flash memory.

  The decoder 105 is for decoding image data input via the memory card I / F 104.

  The image processing unit 106 converts still image data and moving image data input from the decoder 105 into a reproduction signal that can be displayed on the display unit 107. At this time, OSD (on screen display) information may be superimposed on the reproduction signal in accordance with an instruction from the microcomputer 102. The image processing unit 106 converts still image data and moving image data input from the decoder 105 into output signals that can be output to the external IF 108. At this time, the OSD information can be superimposed on the output signal according to an instruction from the microcomputer 102.

  The display unit 107 is a display for displaying still image data and moving image data based on the reproduction signal input from the image processing unit 106. An example of the display unit 107 is an LCD.

  The external I / F 108 is an interface for outputting an output signal input from the image processing unit 106 to the outside. Examples of the external IF 108 include a component terminal, a composite terminal, and an HDMI terminal.

  The communication unit 109 is an interface for communicating with an external device and transmitting / receiving data. The communication unit 109 in this embodiment has an antenna for performing close proximity wireless communication.

  The nonvolatile memory 110 is a storage medium for storing various programs and parameters in advance. It can also be used as an area for temporarily storing parameters in various processes.

  Next, an overview of close proximity wireless communication will be described. In the present embodiment, an example will be described in which the communication device 100 and a non-contact type IC card capable of close proximity wireless communication are close to each other. The IC card described here includes a storage area for writing data, a communication unit for performing close proximity wireless communication, and a microcomputer for controlling the communication operation.

  FIG. 2A is a diagram showing an outline when the communication device 100 and the IC card 200 perform close proximity wireless communication. Reference numerals 109 and 201 denote communication units of the communication device 100 and the IC card 200, respectively, which cannot be visually recognized, and are represented by dotted lines. Further, the IC card 200 includes a display unit 202 for indicating a communication state.

  As shown in FIG. 2A, the user transmits image data stored in the communication device 100 to the IC card 200 by bringing the communication device 100 and the IC card 200 close to each other, or conversely. The image data stored in the communication device 100 can be transmitted to the communication device 100.

  As shown in FIG. 2B, the proximity wireless communication is communication performed when devices come close to each other within a predetermined communicable range. The communicable range is usually performed at a short distance of several centimeters to several tens of centimeters depending on the frequency band. When the communication unit 109 of the communication device 100 and the communication unit 201 of the IC card 200 approach a certain distance, an induced electromotive force is generated. The communication device 100 and the IC card 200 start processing for establishing mutual communication by detecting this electromotive force. Conversely, when the communication units are separated from each other within the communicable range, a sufficient electromotive force is not generated, and thus communication cannot be performed. If the devices are within the communicable range, close proximity wireless communication can be performed in a non-contact manner regardless of whether the devices are in contact with each other.

  The data communication process in this embodiment will be described using the flowchart shown in FIG. In the following description, a case where moving image data is transmitted from the communication apparatus 100 to the IC card 200 will be described. In the data communication processing in the present embodiment, the user of the IC card 200 can select desired data and allow the IC card 200 to receive it with a simple operation.

  When reproduction of moving image data is instructed by a user operation, the microcomputer 102 displays the moving image data stored in the memory card 103 on the display unit 107 in step S301. At this time, the microcomputer 102 may output the moving image data from the external I / F 108 to the external device.

  In step S <b> 302, the microcomputer 102 determines whether it is close to another device, here, the IC card 200. Specifically, it can be determined whether or not the induced electromotive force detected by the communication unit 109 is greater than a predetermined value. If it is determined that they are close to each other, communication with the IC card 200 is established, and the process proceeds to step S303. In addition, referring to a timer (not shown), the time when proximity is detected is stored in the nonvolatile memory 110. If it is determined that they are not close to each other, the process proceeds to step S311.

  In step S <b> 303, the microcomputer 102 determines whether the moving image data is currently being reproduced on the display unit 107. If it is being reproduced, the process proceeds to step S304. If it is not being reproduced, the process proceeds to step S318.

  In step S <b> 304, the microcomputer 102 requests an ID from the IC card 200. The ID is identification information uniquely assigned to the IC card 200 and is used for identifying the device. For example, the serial number of the device can be used as the ID. The microcomputer 102 receives the ID transmitted from the IC card 200 in response to the request and stores it in the nonvolatile memory 110.

  In step S305, the microcomputer 102 waits for a predetermined time, for example, 3 seconds, and then determines whether communication with the IC card 200 is continuously established. If it is determined that it has been established, that is, it has been kept close for a predetermined time, the process proceeds to step S318. If it is not established, that is, if it is determined that communication has been disconnected before the predetermined time has elapsed, the process proceeds to step S318. Note that the predetermined time mentioned here is held in the nonvolatile memory 110 in advance.

  In step S306, the microcomputer 102 recognizes the frame of the moving image data currently being reproduced as an editing point, and starts updating the editing table. If an edit table corresponding to the ID of the IC card 200 has not been created, a new edit table is created. Here, the edit table will be described. The edit table is a table in which edit points and time on the time table of moving image data are stored, and the non-volatile memory 110 holds the edit table. The edit table is created for each ID of the communication partner of the communication apparatus 100. There are two types of edit points: an extraction start point and an extraction end point. The moving image data between the extraction start point and the extraction end point is data to be transmitted to be transmitted to the IC card 200.

  In step S307, the microcomputer 102 refers to the editing table, and determines what number of editing points in the chapter being reproduced is the editing point recognized in step S306. If it is determined that the number is an odd number, the process proceeds to step S308. If it is determined that the number is even, the process proceeds to step S309.

  In step S308, the microcomputer 102 stores the currently reproduced frame as an extraction start point in the edit table corresponding to the ID of the IC card 200. In this embodiment, edit points are set in units of frames, but may be set in units of fields. In addition, as the time information associated with the extraction start point, for example, a frame time code or a time stamp is used.

  In step S309, the microcomputer 102 stores the currently reproduced frame in the edit table of the IC card 200 as an extraction end point. The stored information is the same as the extraction end point.

  The reason why the processes in steps S308 and S309 are performed is as follows. That is, with the above processing, the user can set the extraction start point in the odd-numbered proximity and set the extraction end point in the even-numbered proximity. In other words, the user of the IC card 200 brings the IC card 200 close to the communication device once when the desired scene is reproduced, and closes the desired scene once the desired scene is completed. Can be set as a transmission target. That is, it is possible to select a desired scene by a simple operation of bringing the IC card 200 close and away.

  Here, the currently reproduced frame is used as the editing point. However, for example, the frame reproduced when proximity is detected may be stored, and the frame may be used as the editing point. The frame at the time when communication is established may be used as the editing point.

  Further, in consideration of a time lag from when the IC card 200 is brought close to the communication unit 109 until communication is established, a certain number of frames before the frame when communication establishment is established may be designated as an editing point. In addition, in consideration of inter-frame compression such as MPEG, an adjacent GOP break may be used as an edit point. Alternatively, the image processing unit 106 may be used to recognize scene breaks, and the frame may be used as an edit point.

  Note that the edit point is not necessarily one extraction start point and one extraction end point. After the extraction start point and the extraction end point are set one by one in the proximity of two times, the extraction start point and the extraction end point are newly set when the third approach and the fourth approach are performed. In this case, two scenes, that is, a scene sandwiched between the first and second edit points and a scene sandwiched between the third and fourth edit points are transmission targets.

  In step S310, the microcomputer 102 generates a thumbnail image of the frame recognized as the edit point in step S306, and transmits it to the IC card 200 in association with the time code of the edit point. At this time, information indicating whether the edit point is the extraction start point or the extraction end point is also transmitted in association with it. Here, the thumbnail image and the time code are output to the IC card 200, but other information may be transmitted as long as the data represents the characteristics of the extraction point.

  FIGS. 4A and 4B show screens displayed on the display unit 202 of the IC card 200 when the IC card 200 receives the thumbnail image and time code transmitted in step S310.

  FIG. 4A is a screen displayed when the edit point is the extraction start point. As shown in FIG. 4A, the IC card 200 displays a thumbnail 401 and a time code 402 as extraction start points. Furthermore, a guidance 403 indicating that the extraction end point can be set is displayed by bringing the communication device 100 and the IC card 200 closer together. As a result, the user can easily grasp the next operation.

  FIG. 4B is a screen displayed when the editing point is the extraction end point. In addition to the display of FIG. 4A, an extraction end point thumbnail 411 and a time code 412 are displayed in the same manner as the extraction start point. A display of the total time 413 of the moving image data to be extracted is also displayed. This total time is calculated based on the difference between the time code at the extraction end point and the time code at the extraction start point.

  By confirming the screens shown in FIGS. 4A and 4B, the user can easily grasp the outline of the moving image data to be transmitted. 4A and 4B has been described as being displayed on the display unit 202 of the IC card 200, it may be displayed on the display unit 107 of the communication apparatus 100.

  Returning to FIG. In step S <b> 311, the microcomputer 102 determines whether or not the reproduction of the chapter started in step S <b> 301 or step S <b> 315 described later has been completed. If it is determined that the process has been completed, the process proceeds to step S312. If it is determined that the process has not been completed, the process returns to step S302, and the proximity of the IC card 200 is confirmed.

  In step S312, the microcomputer 102 refers to the editing table of the IC card 200, and determines how many editing points are set for the chapter determined to have been reproduced in step S310. If the number is even, the process proceeds to step S314. If it is an odd number, the process proceeds to step S313.

At the time of step S313, although the extraction start point has been set, the reproduction of the chapter has ended without the extraction end point being set thereafter. Therefore, the microcomputer 102 stores the last frame of the chapter being played back in the nonvolatile memory 110 as an extraction end point candidate. The handling of this extraction end point candidate will be described later.
In step S314, the microcomputer 102 determines whether all moving image data has been reproduced. If it is determined that the reproduction has been completed, the process proceeds to step S316. If it is determined that the reproduction has not been completed, the process proceeds to step S315.
In step S316, the microcomputer 102 determines how many edit points are set for the chapter determined to have been reproduced in step S310. If the number is even, the process proceeds to step S302. If it is an odd number, the process proceeds to step S317.

  At the time of step S317, extraction end point candidates are stored in step S313. Therefore, the microcomputer 102 sets the extraction end point candidate, that is, the last frame of the chapter being played back as the extraction end point, and returns the process to step S302. In this way, the extraction end point is automatically set by the communication apparatus 100 without necessarily setting both the extraction start point and the extraction end point by a user operation.

  In step S <b> 315, the microcomputer 102 reproduces the moving image data of the next chapter from the memory card 103 and displays it on the display unit 107.

  If the editing point of the previous chapter is an odd number, the editing point set first in the new chapter can be set as the extraction end point. That is, it is possible to set the transmission target from the last editing point of the previous chapter to the first editing point of the new chapter as one scene across the chapters.

  Also, the last edit point of the previous chapter to the extraction end point candidate set in step S313 can be transmitted as one scene, and the edit point set first in the new chapter can be the extraction start point. Is possible.

  Further, the communication apparatus 100 can allow the user to select which of the above two setting methods is adopted. For example, when the first editing point is set in a new chapter, a screen as shown in FIG. 5 is displayed on the display unit 202 of the IC card 200 or the display unit 107 of the communication device 100.

  In FIG. 5, 501 is a frame of the first edit point in a new chapter, and 502 is an extraction end point candidate, that is, the last frame of the previous chapter. Reference numeral 503 denotes a selection display for causing the user to select which one is the extraction end point.

  When “chapter break” is selected, the microcomputer 102 sets the extraction end point candidate as the extraction end point. When “designated position” is selected, the microcomputer 102 sets the first edit point in the new chapter as the extraction end point. Then, the count of edit points in the new chapter is set to zero. That is, when the edit point is set by performing the second approach next time, it is determined as the first edit point in step S305, and the point is set as the extraction start point.

  Here, processes 212 and 213 are performed for each chapter break, but may be performed at a change point such as a change point of date data, a change point of scene information, or event information.

  Up to this point, the editing point is set for the moving image data and the transmission target is determined. Next, the process after step S318 is demonstrated. The processes after step S318 are processes for transmitting moving image data to the IC card 200 based on the set editing points.

  In step S318, the microcomputer 102 refers to the edit table of the IC card 200, and determines how many edit points are set for the chapter reproduced in steps S301 and S315. If the number is even, the process proceeds to step S320. If the number is odd, the process proceeds to step S319.

  In step S319, the microcomputer 102 sets the last frame of the chapter being played back as the extraction end point.

  In step S320, the microcomputer 102 refers to the editing table, reads the corresponding moving image data from the memory card 103, extracts moving image data from the extraction start point to the extraction end point, and generates new moving image data.

  In step S <b> 321, the microcomputer 102 transmits the newly generated moving image data to the IC card 200.

  The processing for transmitting moving image data from the communication apparatus 100 to the IC card 200 has been described above.

  Here, the purpose of the process of step S305 will be described in detail. In step S305, it is determined whether or not the IC card 200 is close to the communication apparatus 100 for a predetermined time such as 3 seconds. If the proximity is shorter than a predetermined time, that is, short-time communication, an editing point is set. If the proximity is long, that is, long-time communication, actual moving image data is transmitted based on the editing point.

  That is, the user can change the operation of the communication device 100 by changing the time for which the IC card 200 is close to the communication device 100. When it is desired to set an editing point, the IC card 200 is moved close and then immediately released. When moving image data is actually acquired, the IC card may be kept close to the communication device.

  By doing in this way, the user can use the two functions of setting edit points and acquiring moving image data only by a simple operation of bringing the IC card 200 close and away.

  Next, a case where a plurality of IC cards are brought close to the communication device will be described. FIG. 6 is a diagram illustrating processing in which two IC cards, IC card A and IC card B, are close to communication device 100 and transmit moving image data from communication device 100 to each IC card.

  Reference numeral 600 denotes a time-series display of the reproduction order of the moving image data being reproduced. The first chapter, the second chapter, and the third chapter are reproduced in order from the left, and the reproduction ends.

  Further, the lower side of the reproduction order 600 indicates the timing of the proximity of the IC card A and the IC card B. The IC card A is close to the timing 601 at which the first chapter is being reproduced, the timing 602 at which the third chapter is being reproduced, and the timing 603 after the reproduction is completed. Assume that the proximity of the timings 601 and 602 is a short-time proximity for setting an edit point.

  The IC card B is close to the timing 604 at which the second chapter is being reproduced, 605 at which the second chapter is being reproduced, and 606 at which the third chapter is being reproduced. Assume that the proximity of timings 604 and 605 is a short-time proximity for setting an edit point, and the proximity of timing 606 is a long-time proximity for transmitting moving image data.

  A specific operation will be described below. First, during the first chapter reproduction, the proximity of the IC card A is detected by the communication device 100 (timing 601). The microcomputer 102 refers to the ID of the adjacent IC card, reads the edit table of the IC card A, and writes the extraction start point (00:01:00).

  Next, the proximity of the IC card B is detected by the communication device 100 during the second chapter reproduction (timing 604). The microcomputer 102 reads the edit table of the IC card B with reference to the ID of the adjacent IC card, and writes the extraction start point (00:02:00).

  Next, the proximity of the IC card B is detected by the communication device 100 during the second chapter reproduction (timing 605). The microcomputer 102 refers to the ID of the adjacent IC card, reads the editing table of the IC card B, and writes the extraction end point (00:02:30).

  Next, during the third chapter reproduction, the IC card A is detected by the communication device 100 (timing 602). The microcomputer 102 reads the edit table of the IC card B with reference to the ID of the adjacent IC card, and writes the extraction end point (00:03:30).

  The states of the editing tables of the IC card A and the IC card B at this time are shown in FIGS. 7A and 7B, respectively.

  Next, during the third chapter reproduction, the IC card B is detected by the communication device 100, and communication is established for a predetermined time or more (timing 606). Then, the microcomputer 102 reads the edit table of the IC card B with reference to the ID of the adjacent IC card. Then, the moving image data is read from the memory card 103, moving image data from the extraction start point (00:02:00) written in the editing table to the extraction end point (00:02:30) is extracted, and a new moving image is extracted. Create data. Then, the created moving image data is transmitted to the IC card B.

  Next, after the reproduction is completed, the IC card B is detected by the communication device 100 (timing 603). Although this proximity has not been performed for a predetermined time or more, since the reproduction has been completed, the communication apparatus 100 starts a process of transmitting moving image data regardless of the time of proximity (step S303 / No). The microcomputer 102 reads the edit table of the IC card A with reference to the ID of the adjacent IC card. Then, moving image data is read from the memory card 103, moving image data from the extraction start point (00:01:00) written in the edit table to the extraction end point (00:03:30) is extracted, and a new moving image is extracted. Create data. Then, the created moving image data is transmitted to the IC card A.

  As described above, the communication apparatus 100 according to the present embodiment manages the edit table using the ID. As a result, even if a plurality of IC cards are moved back and forth and approached to the communication device 100, it is possible to reliably transmit a scene desired by the user of each IC card.

<Second Embodiment>
In the first embodiment, moving image data is transmitted to the IC card by designating an extraction start point and an extraction end point and extracting moving image data between the extraction start point and the extraction end point. On the other hand, in the present embodiment, a desired scene can be transmitted only by setting one edit point.

  This embodiment has many parts in common with the first embodiment. Therefore, description of parts common to the first embodiment is omitted, and parts unique to the second embodiment are mainly described.

  FIG. 8 is a flowchart showing processing according to the present embodiment.

  First, in step S601, the microcomputer 102 displays a screen for allowing the user to select an extraction mode on the display unit 107. The user operates the operation unit 101 to select an extraction mode. The microcomputer 102 stores the extraction mode in the nonvolatile memory 110 based on the user's selection.

Here, the extraction mode is to select a criterion for extracting moving image data with respect to an extraction point set by the user. As the extraction mode, there are a mode for extracting the whole chapter in which the extraction point is set, and a mode for extracting moving image data having the same date as the chapter in which the extraction point is set. Further, there are a mode for extracting several seconds before and after a frame in which edit points are set, and a mode for extracting frames before and after the edit point to set a specified moving image size.
Here, processing for setting an edit point will be described below. The difference between the process in this embodiment and the process in the first embodiment shown in FIG. 3 is that the extraction start point and the extraction end point are not distinguished. That is, in the process of FIG. 3, the two edit points, the extraction start point and the extraction end point, are distinguished according to the number of edit points. Edit points are treated as extraction points.

  Except for the above points, the processing from step S802 to S807 is the same as the processing from step S301 to S306 in FIG. Further, the processes in steps S808 to S810 are the same as the processes in steps S308, S310, and S311. In addition, since the processes in steps S811 and S812 are the same as the processes in steps S314 and S315, description thereof will be omitted.

  Next, processing for transmitting moving image data in step S813 and subsequent steps will be described. The transmission process in the present embodiment is performed based on the extraction mode set in step S801.

  In step S813, the microcomputer 102 reads the editing table of the IC card 200. Then, the moving image data is read from the memory card 103, and the moving image data is extracted based on the extraction point and the extraction mode set in step S601 to generate new moving image data.

  In step S <b> 814, the microcomputer 102 transmits the newly generated moving image data to the IC card 200.

  As described above, the communication apparatus 100 according to the present embodiment can extract and transmit a desired scene based on one extraction point by first setting the extraction mode. As a result, if the user first sets the extraction mode, the user can cause the IC card 200 to receive a desired scene with a simple operation of bringing the IC card 200 close to the communication device 100 once. It becomes possible.

<Other embodiments>
In the above embodiment, the IC card has been described as an example of the communication partner of the communication apparatus. For example, the present invention can be applied to a mobile phone, an imaging device, an image viewer, and the like. Further, the communication partner of the communication device 100 may be the same type of device as the communication device 100. For example, the present invention can be applied to communication between mobile phones.

  In the above embodiment, the case where data of a desired scene is acquired from the moving image data has been described as an example. However, the present invention is not necessarily limited to this case. For example, it can also be used when the user of the IC card 200 acquires desired still image data while still image data stored in the communication device 100 is sequentially displayed.

  Specifically, when the IC card 200 is brought close to the communication device 100 for a time shorter than a predetermined time at a timing when desired still image data is displayed, the communication device 100 adds a flag to the still image data being displayed. Similarly to the case of the first embodiment, the extraction start point and the extraction end point may be set by a plurality of times of proximity, and the communication apparatus 100 may add a flag to all the still image data reproduced during that time. . This flag may be added to the still image data itself, or may be managed by the editing table described above. After that, when the proximity is performed for a longer time than the predetermined time, the communication device 100 transmits the still image data with the flag added to the IC card 200.

  Further, data to be transmitted is not limited to image data, and can be applied to content data such as music data, for example.

  As described above, according to the present invention, not only the acquisition of moving image data, but the processing to be executed can be changed according to the time of proximity, so that the user can approach or release when performing proximity wireless communication. Data transmission and reception can be controlled with a simple operation.

  Further, each of the above embodiments is an example for carrying out the present invention, and it is possible to appropriately combine them.

  Further, the object of the present invention is achieved by programming the functions of the devices according to the above-described embodiments, writing them in advance on a recording medium such as a ROM, and reading the programs by the devices mounted on the ROM. Needless to say.

  In this case, the state read from the ROM and executed realizes the functions according to the above-described embodiment, and the program and the ROM storing the program also constitute the present invention.

  It should be noted that the program that realizes the function of each device according to the above-described embodiment may be provided in a form stored in a recording medium. As the storage medium, for example, a semiconductor medium (ROM, nonvolatile memory, etc.), an optical medium (DVD, MO, MD, CD, etc.), and a magnetic medium (magnetic tape, flexible disk, etc.) can be used.
