Description

  The present invention relates to a moving image processing technique in a communication terminal device.

  In recent years, communication terminal devices such as mobile phones having a moving image recording function have been widely used. In addition, with recent advances in imaging technology and video coding technology, various technologies for enabling high-quality moving images to be recorded in communication terminal devices have been proposed (for example, Patent Document 1).

  Further, the communication terminal device may have a person recognition function. In relation to this, Patent Document 2 shows various examples of usability improvement by associating the person information specified from the captured image with the address book information.

  There are various uses of moving images recorded by a communication terminal device, and not only reproduction by the communication terminal device but also e-mail (hereinafter simply referred to as “mail”) so that it can be reproduced by another communication terminal device. In many cases, it is attached and transmitted to the other communication terminal device. In relation to this, Patent Document 3 discloses a mobile communication terminal with a mail function that transmits an email having an optimum capacity from the receivable capacity of the destination and the mail transmittable capacity of the terminal itself.

  In other words, a high-quality moving image is an image having a large code amount per bit. That is, when a high-quality moving image recorded for the same time and a low-quality moving image are compared, the high-quality moving image has a larger file capacity.

  In addition, as shown in Patent Document 3, generally, there is a capacity limit for sending and receiving mail. Therefore, when performing transmission / reception processing by attaching a high-quality moving image file to an e-mail, the file capacity is large, so that the transmission / reception capacity limit may be violated and the moving image file may not be transmitted / received reliably. Then, the receiving side communication terminal device cannot accurately reproduce the original moving image.

  The present invention has been made in view of the above circumstances, and provides a communication terminal device and a program that can prevent transmission and reception of recorded high-quality moving images from being attempted as much as possible and can expect accurate reproduction on the receiving side. For the purpose.

Person recognition means for discriminating and recognizing the image of the person stored in the person management information storage means from the images of the moving image data;
The communication destination of the e-mail corresponding to the person image recognized by the person recognition unit is acquired from the person management information storage unit, and the capacity limit corresponding to the acquired communication destination of the e-mail is acquired from the limit capacity information storage unit. Limited capacity acquisition means to acquire;
An image file in which the moving image data stored in the moving image data storage unit is recorded, and an image file generation unit that generates an image file having a capacity less than or equal to the limit capacity acquired by the limit capacity acquisition unit;
The e-mail transmission / reception means transmits the image file generated by the image file generation means to the communication destination of the e-mail acquired from the person management information storage means.
It is characterized by that.

The program according to the second aspect of the present invention is:
On the computer,
An imaging step of performing imaging by the imaging means;
A moving image data storage step of storing moving image data obtained as a result of imaging by the imaging unit in a moving image data storage unit;
A person recognizing step for causing the person recognizing means to recognize and recognize the image of the person stored in the storage means in advance in the image of the moving image data;
An email communication destination acquisition step for acquiring an email communication destination corresponding to the image of the person recognized in the person recognition step;

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram illustrating an appearance of a communication terminal device 10 according to the present embodiment, and FIG. 2 is a block diagram illustrating an internal configuration of the communication terminal device 10. The communication terminal device 10 is, for example, a mobile phone. Note that the communication terminal apparatus according to the present invention may be embodied by a PHS (Personal Handy-phone System), a PDA (Personal Digital Assistant), a PC (Personal Computer), or the like.

  The communication terminal device 10 includes an operation unit 101, a control unit 102, an imaging unit 103, a storage unit 104, an image capacity monitoring unit 105, a communication unit 106, a display unit 107, an audio processing unit 108, and a multiplexing unit. / Separation unit 109, external memory driver 110, external memory I / F unit 111, and image recognition unit 116.

  The operation unit 101 includes various key buttons and the like, receives an operation input from the user, and sends a signal related to the received operation input to the control unit 102. The operation unit 101 accepts, for example, a power ON / OFF operation of the communication terminal device 10, an input operation for inputting a telephone number or creating a mail text, an operation related to imaging of a subject, and the like from the user.

  The control unit 102 includes a CPU (Central Processing Unit), a main storage device, and the like (none of which are shown), controls each unit of the communication terminal device 10, and is based on various programs stored in the storage unit 104. Thus, each process described later, such as recording and playback of moving images, creation and transmission of electronic mail (hereinafter simply referred to as “mail”), is executed. In the present embodiment, the control unit 102 has functions such as person recognition, image file writing, capacity determination, transmission target image file acquisition, transmission image management information generation, and the like.

  The imaging unit 103 includes a CCD (Charge Coupled Device), an A / D converter, and the like, converts a moving image obtained by imaging a subject from an optical signal to an analog electrical signal, and converts the analog electrical signal to a digital signal. Convert. For example, the imaging unit 103 images the face, scenery, characters, and the like of a person who is a subject, and converts the resulting moving image into a digital signal (image data) that can be handled by the control unit 102. The control unit 102 outputs the image data from the imaging unit 103 to the display unit 107 as necessary.

  The communication unit 106 includes an antenna 114 and the like, and transmits and receives data to and from other communication terminal devices and information processing devices by a predetermined communication method in a mobile phone. The communication unit 106 transmits / receives data to / from a base station, a location server, a GPS (Global Positioning System) satellite, and the like, and acquires position coordinate information (longitude, latitude) and the like of the communication terminal device 10. The communication unit 106 also performs communication processing for the communication terminal device 10 to access the Internet. Note that the communication unit 106 may be configured to enable communication using a plurality of communication methods such as CDMA (Code Division Multiple Access), EV-DO (Evolution Data Only), and wireless LAN.

  The display unit 107 includes a display device such as an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display, and displays an image captured by the imaging unit 103, for example. In addition, the display unit 107 displays various information necessary for the user to use the functions of the communication terminal device 10 (for example, the power state, the radio wave intensity, the remaining battery level, the server connection state, and the like, the presence / absence of unread mail) , The input telephone number, the telephone number of the caller at the time of incoming call, the contents of transmitted / received mail, moving images and still images, received data such as a Web screen when connected to the Internet, etc.

  When the user records a moving image on the communication terminal device 10, the user presses a predetermined key button provided on the operation unit 101 at a desired timing while monitoring the image displayed on the display unit 107. Start recording. The display unit 107 may be composed of two or more display devices, main and sub.

  The storage unit 104 includes, for example, a readable / writable non-volatile semiconductor memory such as a flash memory, and is obtained by the imaging unit 103 or acquired by communication with another communication terminal device or the like. A restriction table 201, an image management table 202, and a person management table 203 are stored. In other words, the storage unit 104 functions as a limited capacity information storage unit, a related image file information storage unit, and a person management information storage unit in the claims. The storage unit 104 also stores various other data handled by the communication terminal device 10, application software such as a mailer (e-mail client), a program for realizing functions unique to the present invention, and the like.

  As shown in FIG. 3, the capacity limit table 201 is a data table in which limit capacity information in which a capacity limit ID, a processing type, a communication destination, and a limit capacity are associated is entered. “Processing type” indicates whether the processing content subject to capacity limitation is transmission or reception, and “communication destination” indicates information (domain name in the present embodiment) that identifies a communication partner.

  “Limited capacity” indicates a capacity (data size) provided with a restriction for each processing type or communication partner. Specifically, when the processing type is reception, the maximum data size that the communication terminal apparatus 10 can receive in one communication is shown. When the processing type is transmission, the maximum data size that can be transmitted to the communication partner in one communication is indicated.

  In the example of FIG. 3, it is shown that the limited capacity when the processing type is reception is 3 MB regardless of the communication partner. On the other hand, the capacity limit at the time of transmission differs depending on the communication partner. When the domain name is “@ abc.com”, 1 MB, when the domain name is “@ def.com”, 3 MB, and the domain name is “@ “ghi.com” indicates 2 MB.

  In the capacity limit table 201, only one record (limit capacity information of capacity limit ID “L_01”) is entered in the initial state (shipment state). Then, when mail is transmitted / received to / from a new communication destination, the limited capacity information about the communication destination is automatically entered by the control unit 102. Note that the user may enter the capacity limit information of a new communication destination via the operation unit 101, or the entered capacity limit information may be updated.

  In addition, the limited capacity information may include various items other than the above. For example, an item indicating the type of the communication terminal device used by the user of the communication partner may be included.

  The image management table 202 is information for appropriately managing the moving image file 115 stored in the storage unit 104. The image management table 202 is referred to when any processing such as recording, copying, deletion, reproduction, transmission, or the like is performed on an image file. The image management table 202 is newly created if it does not exist in the storage unit 104 when the image file is recorded, and the content is updated if it already exists.

  In the image management table 202, as shown in FIG. 4, image file information in which an image ID of a moving image, a file name, a bit rate, a recording time, a file capacity, and a related file are associated is entered. Data table. In the example of FIG. 4, the image ID “I — 01” is assigned to the image file information entered at the top, and the file name is “MImg0001.mp4”. This image file has a recording time of 3 seconds, a bit rate of 1 Mbps, and a capacity of 3 MB. Further, it is shown that this image file is related to each image file of the image ID “I — 02” and the image ID “I — 03”.

  In the “related file”, when a series of recorded moving image data is divided into a plurality of image files and stored, information of other continuous image files is stored as a related file. Specifically, the image ID of another related image file is stored. In the example of FIG. 4, from the file name and related file information, the capacity of the image file with the image ID “I — 01” reaches the limit capacity (3 MB) while recording the moving image data. It can be seen that the image file of ID “I — 02” is stored. Further, since the capacity of the image file with the image ID “I — 02” has reached 3 MB, it can be seen that the subsequent moving image data is stored in the image file with the image ID “I — 03”.

  That is, the image file with the image ID “I — 01” and the image files with the image ID “I — 02” and the image ID “I — 03” are different, but are image files constituting a series of moving image data. Therefore, these three image files should be handled as one moving image data. Details of the handling will be described later.

  As shown in FIG. 5, the person management table 203 includes a person ID, a person name, a person image (particularly, a still image of a face that can clearly identify the person), a telephone number, This is a data table in which e-mail addresses and the like are entered as various information related to the associated person. In the example of FIG. 5, the person ID “P — 01” is assigned to the person information entered at the top, the person name is “Iroha”, and the still image of the face that well represents the characteristics of this person is “A ". The person's telephone number is “090-123”, and the mail address is “iroha@abc.com”.

  Returning to FIG. 2, the external memory I / F unit 111 is a hardware interface for connecting to an external memory 112 such as a microSD card or a USB (Universal Serial Bus) memory, and the external memory driver 110 includes an external memory I / F. The F unit 111 is controlled. For example, when many image files are stored in the storage unit 104, there is a possibility that the free space of the storage unit 104 is insufficient. Therefore, the communication terminal device 10 according to the present embodiment includes the external memory I / F unit 111 and the external memory driver 110 so that an image file is recorded in the external memory 112 or an image stored in the external memory 112. The file can be read. Note that the external memory I / F unit 111 is preferably provided on the side surface of the housing of the communication terminal device 10 or the like in order to prevent the external memory 112 from being accidentally dropped during a user operation.

  The image capacity monitoring unit 105 operates at the time of recording a moving image, monitors the volume of moving image data and the capacity of the image file accumulated in real time in a buffer (not shown) of the storage unit 104, and sends the result to the control unit 102. Notice.

  The audio processing unit 108 compresses the audio data input from the audio input / output terminal 113 to generate audio compression data, and supplies the generated audio compression data to the multiplexing / demultiplexing unit 109. Also, the audio processing unit 108 decompresses the audio compression data supplied from the multiplexing / demultiplexing unit 109 to restore it to audio data, and outputs the restored audio data from the audio input / output terminal 113.

  The multiplexing / separating unit 109 compresses the moving image data obtained by the imaging unit 103 to generate compressed image data, multiplexes the generated compressed image data with the compressed audio data generated by the audio processing unit 108, and stream data. Is generated. The multiplexing / separating unit 109 reads stream data from the storage unit 104 or the external memory 112 and separates the stream data into compressed image data and compressed audio data. Then, the separated compressed image data is decompressed and restored to moving image data, the restored moving image data is supplied to the display unit 107, and the separated audio compression data is supplied to the audio processing unit 108.

  The image recognition unit 116 recognizes subject information included in the moving image data input from the imaging unit 103 and specific image information included in an image such as a recorded moving image or still image. The specific image information is, for example, a human face or physical characteristics, and the communication terminal apparatus 10 determines whether or not there is a human face in a range captured from this information or in a recorded image. Determine whether. Furthermore, it is possible not only to determine the presence or absence of a human face but also to identify who the person is. For this purpose, for example, a recognized human face image may be collated with an image pattern stored in the storage unit 104 in advance. The image pattern to be collated here is, for example, a still image of a person's face included in the person management table 203 stored in the storage unit 104. Thereby, for example, it is possible to specify who is the subject as the subject during imaging, and who is the person shown in the recorded moving image or still image.

  Note that the image information to be recognized is not limited to a person's face, but is biometric information such as a person's fingerprint, finger vein or iris, or information that can identify things such as characters, symbols, and barcodes. Anything other than examples is acceptable.

  Each function of the image capacity monitoring unit 105, the audio processing unit 108, the multiplexing / separation unit 109, the external memory driver 110, and the image recognition unit 116 is implemented by hardware in a dedicated circuit such as an ASIC (Application Specific Integrated Circuit). The control unit 102 may be realized by a logical process by executing a program stored in the storage unit 104 or the like.

  Next, the moving image recording process executed by the communication terminal device 10 configured as described above will be described with reference to the flowchart of FIG.

  The moving image recording process is started when the user performs a moving image recording process start operation via the operation unit 101. Specifically, for example, the user can start moving image recording processing by selecting an item such as “camera” → “moving image recording” from a menu screen displayed on the display unit 107. Note that the moving image recording process may be started immediately when a specific key button such as a shortcut key is pressed.

  In response to the input of the moving image recording process start operation by the user, the control unit 102 executes a preparation process (recording preparation process) for starting moving image recording (step S101). As a recording preparation process, the control unit 102 initializes various devices necessary for moving image recording and image recognition, initializes a buffer (cache) of the storage unit 104 that accumulates moving image data, and determines the free capacity of the storage unit 104, for example. Execute processing such as investigation and bit rate setting. Further, based on the free space and the bit rate, a process for calculating a movie recordable time and displaying the calculated movie recordable time on the display unit 107 is also performed.

  At this time, since the recording start determination operation from the user described later is not performed (step S104; No), no data is recorded, but the imaging by the imaging unit 103 is started and the captured moving image Data (imaging data) is displayed on the display unit 107 in real time.

  At this point, the person recognition process in the image recognition unit 116 can be started. FIG. 7 illustrates an example of a state in which a person recognition process is performed on imaged data. FIG. 7A shows a state before person recognition. Although three persons as subjects are imaged, the image recognition unit 116 still recognizes it as a person's face. (Of course, the user who is actually operating knows who three people are. This shows that the system is not recognized as a system). FIG. 7B shows a state during human recognition, and the image recognition unit 116 recognizes the presence of three persons from the captured data, but still identifies who each person is. There is no state. (C) of FIG. 7 shows a state after the person recognition, and the image recognition unit 116 has specified who the three persons are.

  The frame in the figure recognizes a person's face and informs the user that the face is focused. Since the person recognition process by the image recognition unit 116 is not performed only once but continuously during imaging, when the subject moves within the frame, the face frame moves accordingly. Also, if the subject's face disappears (turns behind or hides behind the subject), the presence of the person cannot be recognized, so the face frame is not displayed, and the number of subjects has increased or decreased. It is possible to deal with cases appropriately.

  Further, the image recognition unit 116 performs pattern matching between the face image of the subject person and the face image of the person included in the person management table 203. At this time, the subject person and all face images in the person management table 203 may be collated, or only a specific face image preset by the user may be collated. In other words, the former is a recognition method of “who is the subject person?” And the latter is “the person specified by the user is included in the subject?”. Since each method has a merit, the user may be allowed to select from which method the recognition process is performed so that the recognition process can be performed in a user-preferred method.

  Further, it may be determined in which order (priority of collation) the collation between the subject person and the face image recorded in the person management table 203 is performed. As a result, the effect of shortening the verification time can be obtained. The priority of collation may be determined manually by the user, for example, or may be determined in the order of the frequency with which the subject is an email, a call, a moving image, or a still image.

  Further, when it is determined that the subject person does not exist in the person management table 203 as a result of the collation, a person who does not exist in the person management table 203 may be newly registered in the person management table 203. At this time, a message for confirming whether or not to newly register may be displayed on the display unit 107 to prompt the user to select. In addition, the user may be able to set in advance whether or not to encourage new registration. The new registration process and the registration confirmation process may be performed before or after starting the recording process in consideration of not hindering the original recording process.

  Note that whether or not the person recognition process is completed at this point is not an essential condition after step S104. For example, it may be executed for the first time at the start of the recording process in step S105. However, if a person is a subject, the user generally wants to photograph the person's face more clearly. For this purpose, the person recognition process is executed early, and the user confirms that the above-mentioned frame display and the frame correctly touch the face of the person (that is, the person recognition process can be performed correctly). It is desirable to proceed to the recording start determination operation in step S104.

  Returning to FIG. 6, based on the result of the moving image recording preparation process, the control unit 102 determines whether or not moving image recording is possible (step S102). The case where moving image recording is impossible corresponds to, for example, a state where there is no free space for recording a new image file in the storage unit 104, or a device indispensable for moving image recording cannot be used due to some trouble. When moving image recording is impossible in this manner (step S102; NO), the control unit 102 displays an error message such as “Memory recording is not possible because the memory is full” to the user. The fact that the moving image cannot be recorded is notified (step S103). At that time, in consideration of the user's convenience, a message regarding handling of an error such as “Please delete unnecessary data to record a moving image” may be displayed.

  When moving image recording is possible (step S102; YES), the control unit 102 determines whether or not a recording start determination operation has been performed by the user (step S104). For example, the user adjusts the height and inclination of the communication terminal device 10, the distance to the subject, and the like while watching the video imaged by the imaging unit 103 and displayed on the display unit 107, and then presses a predetermined key at a desired timing. Recording start decision operation is performed by operating the icon.

When the recording start determination operation is performed by the user (step S104; YES), the control unit 102 performs control such as changing the state of each device from the recording preparation state to the recording start state, and the imaging unit 103 performs imaging. In addition to accumulating the captured image data obtained in the above as moving image data in the buffer of the storage unit 104, a recording process to be described later is executed (step S105). FIG. 10 illustrates an example of a state in which moving image data is accumulated in the buffer. Here, how much data is stored per second depends on the bit rate set at the start of recording, and the higher the bit rate, the larger the amount of data stored in the buffer per second. Details of FIG. 10 will be described later.
Although not shown, audio data is also stored in a buffer, multiplexed with moving image data, and recorded in a file.

  Thereafter, when an operation for ending moving image recording (moving image recording end operation) or the like is performed by the user, the recording process in step S105 ends, and the control unit 102 provides information about the image file generated by the recording process. (Image file information) is added to the image management table 202 (step S106). At this time, if the image management table 202 does not exist in the storage unit 104, the control unit 102 writes information about the newly generated image file after newly creating the image management table 202. Thus, the moving image recording process ends.

  Next, details of the recording process (step S105) will be described with reference to the flowchart of FIG.

  When the recording process is started, the control unit 102 acquires the capacity restriction table 201 from the storage unit 104 (step S201). Next, the control unit 102 acquires a person recognition result by the image recognition unit 116 according to the procedure described above with reference to FIG. 7 (step S202). The person recognition result means a result of specifying whether or not a person is included in the data being imaged and, if included, who the person is.

  Next, the control unit 102 determines a transmission destination based on the person recognition result acquired in step S202 (step S203). The scheduled transmission destination means a communication destination scheduled to transmit an image file related to the moving image data recorded by the recording process. In the present embodiment, the control unit 102 determines the communication destination of the person of the subject to be recorded in this recording process from the person recognition result as the scheduled transmission destination. If there are multiple subjects and there is a difference in any of the limited capacities, the communication destination of the foremost person in the frame may be determined as the transmission destination, or the closest to the center in the frame A person's communication destination may be determined as a transmission destination. Alternatively, any communication destination may be determined as a scheduled transmission destination according to the priority set for each person or the communication destination set in advance by the user. Furthermore, the communication destination of the person who has received the most access from the user within a predetermined period may be determined as the scheduled transmission destination from the mail communication history, telephone call history, and recorded video and still image data. For example, the access frequency may be ranked based on the number of times of e-mail, phone call, or subject, or from the number of characters in the e-mail, call time, or time included in the video data (time of subject). May be.

  Subsequently, the control unit 102 refers to the person management table 203 and the capacity restriction table 201, and acquires a capacity limit corresponding to the determined scheduled transmission destination (step S204). Here, the procedure for obtaining the limited capacity will be described in detail with reference to FIG.

  The example of FIG. 9 is a case where “person B” is determined as the scheduled transmission destination in step S203 based on the person recognition result in step S202. First, it is clear from the acquired person recognition result that “person A”, “person B”, and “person C” exist as subjects, and the transmission destination is “person B” by the transmission destination determination processing in step 203. Is determined. Next, referring to the person management table 203, it becomes clear from “nihohe@def.com” that is the “mail address” of “person B” that the domain to be transmitted is “@ def.com”. . Next, referring to the capacity limit table 201, it becomes clear that the limit capacity at the time of transmission of “@ def.com” is 3 MB, and the subsequent processing steps are executed based on this limit capacity.

  In addition, when it is difficult to determine one transmission destination in step S203, the control part 102 skips the process of step S203 and acquires a capacity limit by a method different from the process of step S204. The case where it is difficult to determine the transmission destination as one is, for example, immediately after the purchase of the communication terminal device 10 and when there are no various operation histories by the user or when the user preference setting is not made It is. Without the user's operation history and user preference settings, for example, when there are multiple subjects, and when special conditions such as the fact that all of them are standing at the same distance from the camera are overlapped, the transmission destination is determined. It can happen that it cannot be determined.

  Therefore, it is conceivable to obtain the limited capacity by the following method. For example, a value set in advance at the time of shipment or a value arbitrarily set by the user may be used as the limited capacity, or may be the same as the limited capacity when the processing type is “reception” (3 MB in FIG. 3). Good. Alternatively, in the capacity limit table 201, more detailed control is possible when a limit capacity for each communication destination is set in advance by the user before actual communication is performed. For example, when it is clear from the person recognition result in step S202 that “person A”, “person B”, and “person C” exist as subjects (for example, (c) in FIG. 7), the transmission destination is set to one. Regardless of the person management table and capacity limit table, the capacity that can be reliably transmitted to any one of “person A”, “person B”, and “person C” is set as the limit capacity. That is, 1 MB, which is the smallest value among the three limited capacities, may be set as the limited capacity. As described above, there are various methods for determining the capacity limit. In any of these methods, it is effective to improve the usability by deciding that “the transmission can be reliably performed” and “the transmission can be prevented as much as possible” as the first. Is.

  Subsequently, the control unit 102 determines the name of the image file in which the moving image data is recorded (step S205). The name of the image file is determined according to a predetermined naming rule. For example, the control unit 102 assigns an image file name according to a unique naming rule predetermined for each communication terminal device 10 or each manufacturer, or a unified naming rule for ensuring reproduction compatibility between the communication terminal devices 10. decide. In this example, the image file name to be newly opened is described as “MImg0001.mp4”.

  The control unit 102 newly opens the image file (Mimg0001.mp4), and makes the image file writable (step S206).

  The control unit 102 determines whether or not to continue the recording process (step S207). Specifically, it is determined whether or not a moving image recording end operation has been performed by the user. When the user performs the moving image recording end operation (step S207; NO), the control unit 102 stops the accumulation of the imaging data in the buffer and the unwritten moving image data accumulated in the buffer at that time. Is written in an image file (for example, MImg0001.mp4) (step S208). When all the unwritten moving image data is written in the image file, the control unit 102 closes the opened image file (step S209), and ends the present process (recording process).

  On the other hand, when the moving image recording end operation has not been performed (step S207; YES), the control unit 102 sets the data amount of the moving image data accumulated in the buffer based on the monitoring result of the image capacity monitoring unit 105 as a preset threshold. Is determined (step S210). The threshold value here (see FIG. 10) is a parameter used when determining whether or not the accumulated moving image data is written to the file. The control unit 102 stores the moving image data in the buffer until the threshold value is reached. To write to the image file. For example, if the buffer capacity is 2 MB and the threshold value is 1 MB, the accumulated moving image data is written to the image file when the data amount of the moving image data accumulated in the buffer becomes 1 MB or more.

  As a result of the determination, if the data amount of the moving image data accumulated in the buffer has reached the threshold (step S210; YES), the control unit 102 writes the moving image data in the image file (for example, MImg0001.mp4) (step S210). S210) When the threshold is not reached (step S210; NO), the processing from step S207 is repeated.

  Control is performed by the control unit 102, rather than sequentially writing the moving image data stored in the buffer to the image file, it is more likely that the moving image data is accumulated to some extent and then written to the image file at a certain amount. This is because the number of instructions is small, the processing load is reduced, and the processing efficiency and speed can be increased. In addition, depending on the recording medium (flash memory, hard disk drive, various memory cards, etc.) and the file system for recording the image file, for example, there is a characteristic that multiple data of 32 kB can be written efficiently and at high speed. Considering this point, it can be said that it is preferable to accumulate data to some extent and then write it to a file. Of course, such control is not always necessary, and the moving image data stored in the buffer may be sequentially written to the image file. In addition, any value can be set as long as the threshold value is equal to or less than the buffer capacity (for example, 2 MB).

  FIG. 11 is a diagram conceptually showing writing from the buffer to the image file. In FIG. 11, since the data amount of the moving image data accumulated in the buffer reaches the threshold value, the moving image data is sequentially written to the image file (here, “MImg0001.mp4”). Here, as the unit for writing to the image file, it is preferable to select and use a value with good writing efficiency set for each recording medium described above.

  During the writing to the image file, the control unit 102 monitors the capacity of the image file through the image capacity monitoring unit 105, and based on the result, the control unit 102 acquires the capacity of the image file in step S204. It is determined whether or not the limit capacity has been reached (step S212). In this example, since the capacity limit is 3 MB, the control unit 102 determines whether or not the capacity of the image file has reached 3 MB. Alternatively, it may be determined whether or not the size written from the buffer to the image file has reached 3 MB.

  As a result of the determination, when the limit capacity has not been reached (step S212; NO), the processing from step S207 is repeatedly executed.

  On the other hand, when the capacity of the image file reaches the limit capacity (step S212; YES), the image file (for example, “Mimg0001.mp4”) is closed (step S213). Then, the control unit 102 opens a new image file to continue the recording process (step S214). In this example, the file name of this image file is “MImg0002.mp4”. After opening a new image file, the processing from step S207 is repeatedly executed. In FIG. 12, since the capacity of the image file “Mimg0001.mp4” has reached the limit capacity (here, 3 MB) while the moving image data stored in the buffer is being written to the image file “Mimg0001.mp4”, it is stored in the buffer. The state of writing the remaining moving image data in the newly opened image file “Mimg0002.mp4” is shown.

  Thereafter, as long as the user does not perform the moving image recording end operation (step S207; NO), the above process is repeatedly executed. For example, as a result of continuing the recording process, when the capacity of “MImg0002.mp4” reaches 3 MB (step S212; YES), the control unit 102 closes “MImg0002.mp4” (step S213), and the image file “MImg0003”. .Mp4 "is newly opened, and the moving image data stored in the buffer is written to" MImg0003.mp4 "(step S211).

  When the above recording process is completed, as described above, the control unit 102 updates the image management table 202 (step S106 in FIG. 6). For example, if the image management table 202 does not exist in the storage unit 104 at the time of recording the moving image, the control unit 102 creates a new image management table 202 and then creates a newly generated image file (for example, “Mimg0001.mp4”, Information (image file information) about “MImg0002.mp4” and “MImg0003.mp4”) is written (see FIG. 4).

  As described above, even when a moving image is recorded with high image quality, it is possible to generate an image file that does not conflict with the capacity limit at the time of mail transmission.

  In this embodiment, the limited capacity is determined before the start of recording, and thereafter, the limited capacity is not changed until the end of recording. However, it is possible to change the capacity in the middle.

  Since the image recognizing unit 116 always recognizes the person in the subject even after the recording is started, for example, it can also be recognized that the subject person has been replaced since the start of the recording. For example, in the case of a person X that has been shown for 1 second immediately after the start of recording and a person Y that has been shown from 1 second to 5 seconds after the start of recording, the recorded video is shown because the person Y is shown longer. The possibility of sending to At this time, if the limited capacity corresponding to the person X is 3 MB and the limited capacity corresponding to the person Y is 1 MB, a moving picture recorded with the limited capacity 3 MB cannot be transmitted to the person Y because it violates the limited capacity. However, if the limited capacity is changed to 1 MB in the middle of recording, it can be transmitted to the person Y. Of course, before changing the limit capacity, it is desirable to confirm that the size of the already recorded image file is less than 1 MB.

  Furthermore, at the start of recording, a minimum limit capacity is set regardless of the subject (for example, 1 MB), and the person in the subject immediately before the recording of the image file proceeds to reach the set 1 MB. If the capacity limit corresponding to the person of the subject is larger than 1 MB, the capacity limit may be changed (for example, 3 MB). Initially, by setting the limit capacity to the minimum value, it is possible to obtain an effect of preventing transmission of the image file from being attempted as much as possible. In addition, it is possible to reduce the number of image files, which is convenient for management, even if the total capacity of the recorded image files is the same by changing the limit capacity to a large value on the way. can get.

  Next, processing (image file transmission processing) when the image file generated by the above-described moving image recording processing is attached to a mail and transmitted will be described with reference to the flowcharts of FIGS. 13 and 14.

  The user can start the image file transmission process by selecting an item such as “mail” → “new creation” from the menu screen. Alternatively, the image file transmission process may be started immediately by pressing a predetermined key such as a shortcut key. In particular, in the present embodiment, unlike normal mail transmission, it is a process of transmitting mail with video data attached, and further transmitting single video data composed of a plurality of image files. Etc. is convenient because it can be clearly differentiated from normal mail transmission and can prevent user confusion. When such an instruction is input, the control unit 102 starts an image file transmission process.

  The control unit 102 accepts designation of a mail transmission destination (destination) from the user (step S301). Next, the control unit 102 receives designation of an image file to be attached from the user (step S302). For example, for each image file stored in the storage unit 104, the control unit 102 displays a list of file names, thumbnails, and the like on the display unit 107. The user selects an image file to be attached to the mail from the displayed attachment candidates. FIG. 15A shows an example of the display screen of the display unit 107 after the image file is selected.

  The control unit 102 determines whether the image file designated by the user can be transmitted to the destination (step S303). Specifically, the control unit 102 refers to the image management table 202 to acquire the file capacity of the image file specified by the user, and this file capacity is the destination (communication destination) indicated in the capacity restriction table 201. It is determined whether the capacity is equal to or less than the limit capacity. As a result, when transmission is impossible, that is, when the file size of the image file specified by the user exceeds the limit capacity of the destination (step S303; NO), the control unit 102 displays an error message on the display unit 107 ( Step S304), the process (image file transmission process) is terminated.

In addition, although S303 was performed in order to transmit a file more reliably, this process may be skipped. This is because in the present invention, recording is performed so as not to exceed the limited capacity in S212, and S303 is always YES. By skipping S303, the number of transmission processing steps can be reduced.
Alternatively, information indicating whether the file to be transmitted is recorded so as not to exceed the capacity limit, or information indicating whether the file has not exceeded the capacity limit is stored. May be. If it is determined from these pieces of information that the recording has been recorded so as not to exceed the capacity limit or has been checked, S303 may be skipped. Here, these pieces of information only have to play the role of a flag. For example, it is possible to use 1-bit information so that checked; 1; unchecked; 0. These pieces of information may be stored in the storage unit 104 in association with the image file. The storage destination and storage method of the information are not limited to this, and other means may be used as long as the relationship between the image file and the bit information becomes clear.

  On the other hand, when transmission is possible, that is, when the file capacity of the image file specified by the user is equal to or smaller than the limit capacity of the destination (step S303; YES), the control unit 102 refers to the image management table 202 and It is determined whether or not there is another related image file (step S305). If there is no related image file (step S305; NO), the control unit 102 sends a mail attached with the image file to the destination. (Step S306), and this process is terminated. It is assumed that the mail subject and text are input by the user via the operation unit 101 as necessary.

  On the other hand, when a related image file exists (step S305; YES), the control unit 102 executes a related image file transmission process (step S307). Note that the control unit 102 may display a list of related image files on the display unit 107 and present it to the user as shown in FIG. 15B before executing the related image file transmission process. . Further, as shown in FIG. 15C, it may be confirmed to the user whether or not the related image file is also transmitted. In this case, if “No” is selected by the user, the control unit 102 may transmit an email attached with only the image file received in step S302.

  FIG. 14 is a flowchart illustrating a procedure of related image file transmission processing. The control unit 102 acquires the image file to be transmitted from the storage unit 104 (step S401). Here, immediately after the start of the related image file transmission process, the image file designated by the user accepted in step S302 of FIG. 13 becomes the image file to be transmitted. When the image file to be transmitted is acquired, the control unit 102 transmits the mail attached with the image file to the destination designated by the user accepted in step S301 in FIG. 10 (step S402).

  Next, the control unit 102 determines whether there is an untransmitted image file (step S403). When there is an untransmitted image file (step S403; YES), the control unit 102 acquires the next transmission target image file from the storage unit 104 (step S401). At this time, there are a plurality of untransmitted image files. When the image ID exists, the control unit 102 acquires the image file as the transmission target in order from the youngest image ID (that is, in ascending order). Then, the control unit 102 transmits an email attached with the image file to the destination (step S402).

  If there is no untransmitted image file (step S403; NO), image file information for each transmitted image file is generated and transmitted as transmitted image management information (step S404), and this process (related image file transmission process) ) Ends. For example, when the image file “Mimg0001.mp4” is selected by the user, “MImg0001.mp4” → “MImg0002.mp4” → “MImg0003.mp4” is sequentially transferred to the other party ( For example, it is transmitted to “@ def.com”). In this case, the same transmission image management information as the content of the image management table 202 shown in FIG. 4 is generated. The transmission image management information is not limited as long as related images can be managed appropriately even at the transmission destination, and it is sufficient that the transmission image management information includes at least information indicating the relationship between the transmitted image files. .

  There are various transmission modes of the transmission image management information. For example, as in this example, the image file may be transmitted prior to transmission of the image file, not after transmission of all the image files. Alternatively, instead of transmitting the image file separately from the image file, when transmitting one of the image files, the transmission image management information may be embedded in the header of the mail. The transmission image management information corresponding to only the image file (that is, image file information) may be embedded in the header part. Alternatively, the transmission image management information may be embedded in the header portion of the image file.

  FIG. 16 is an example of a screen displayed on the display unit 107 during execution of the related image file transmission process. FIG. 16A is a diagram showing an example of a display screen when an e-mail attached with the first image file (for example, “Mimg0001.mp4”) is transmitted in step S402. In FIG. 16A, the progress bar at the center of the screen indicates the progress of mail transmission. In this example, the progress bar indicates the transmission status of the entire image file related to “MImg0001.mp4”, not the transmission status of the mail with “MImg0001.mp4” attached. That is, for example, the total progress when sending three mails: mail 1 with “MImg0001.mp4” attached, mail 2 with “MImg0002.mp4” attached, and mail 3 with “MImg0003.mp4” attached. Indicates the situation.

  FIG. 16A is a display example during transmission of the first mail (the above-mentioned mail 1) of all three mails, so the progress bar indicates 33%, which is 1/3 of 100%. Yes. FIG. 16B is a display example during transmission of the second mail (the mail 2 described above), so the progress bar indicates 67%, which is 2/3 of 100%.

  As described above, according to the communication terminal device of the present invention, an image that stores moving image data in consideration of a mail reception limit capacity at a destination (communication destination) to which an image file is to be transmitted is recorded. Determine the capacity of the file. Therefore, the image file relating to the recorded moving image can be reliably transmitted to the communication partner. Further, the capacity limit of the image file is determined based on the person recognition result at the time of moving image data recording. Therefore, it is possible to record the image file relating to the recorded moving image with the most suitable file capacity for transmission to the subject person.

  In addition, when a series of moving image data is divided into a plurality of image files and stored at the time of moving image recording, other communication terminal devices or the like are used to generate and manage information indicating the relationship between these image files. When transmitting an image file to the image file, it is possible to transmit the related image file without omission by checking the relationship of the image file to be transmitted. In addition, when playing back a moving image with the communication terminal device of the present invention, it is possible to play back the related image files in the correct order by examining the relationship of the image files to be played back, and to accurately play back the recorded moving image data. it can. Furthermore, when an image file is transmitted to another communication terminal device or the like, information indicating the relationship of the image file is also transmitted, so that a moving image can be reproduced without any problem on the communication terminal device or the like on the receiving side.

  As described above, the present invention uses the result of person recognition to determine the capacity limit of the image file. This is the original purpose that the communication terminal device including the camera and the image recognition unit captures the person (face) beautifully. Various hardware, programs, and information necessary for achieving the above are effectively used. Since the components used for other functions are shared, the present invention can be applied to the communication terminal device at a low cost, and the processing load on the system is minimal when determining the capacity limit. There is.

  In addition, this invention is not limited to the said embodiment, Of course, the various change in the range which does not deviate from the summary of this invention is possible.

For example, in the present embodiment, each process has been described assuming that the image data that can be acquired by the imaging unit 103 is moving image data. However, the imaging unit 103 can capture both moving images and still images. Alternatively, it may be selectable between the moving image mode and the still image mode.
In this case, the still image of the face stored in the person management table 203 may be image data captured and recorded in advance in the still image mode by the imaging unit 103.

  Strictly speaking, the capacity of the mail to be transmitted affects not only the capacity of the attached image file and the like, but also the number of characters in the mail text. In this regard, for example, the capacity limit table 201 (see FIG. 3). In the capacity limit of each capacity limit information set in the above, it is sufficient to subtract the capacity of the assumed mail body in advance. For example, when the transmission limit capacity is 3 MB and the predicted mail body capacity is a maximum of 0.1 MB, the limit capacity set in the capacity limit table 201 may be 2.9 MB or less. The maximum capacity of the mail text can be predicted with an almost accurate value, for example, by limiting the number of characters that can be input. In this case, if the subject and text used when transmitting the related image file are standardized, the prediction accuracy is further improved.

  In addition, by applying the program executed by the communication terminal device 10 of the above embodiment to an existing mobile phone or the like, the mobile phone or the like can also function as the communication terminal device according to the present invention.

  Such a program distribution method is arbitrary. For example, a computer-readable recording medium such as a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), an MO (Magneto Optical Disk), or a memory card. It may be stored and distributed in the network, or distributed via a communication network such as a mobile phone network or the Internet.

  In addition, the other communication terminal device or the like that has received the image file and the transmission image management information transmitted from the communication end device 10 of the above-described embodiment need not have the same function as the communication terminal device 10. That is, it is only necessary to have at least a function for reproducing the received image file based on the received transmission image management information. In addition, the communication terminal device 10 may be configured to transmit a moving image reproduction processing program to a destination communication terminal device or the like when transmitting an image file.
