Description

  The present invention relates to a mobile phone terminal device including a camera photographing function unit and a music playback function unit.

  As mobile phone terminal devices have become more sophisticated in recent years, camera shooting functions have come to be attached to almost all models, and models with music playback functions are not uncommon.

In Patent Document 1, in a foldable mobile phone device having an additional function such as a music playback function, a specific function can be used in a state where the casing is folded by operating an operation key provided on the side of the main body. Techniques to do this are disclosed. More specifically, when an operation key (memo key) for recording the message of the other party in the voice memory at the time of incoming / calling is pressed for a long time, the mode shifts to the music playback mode. In the music playback mode, a song is designated by operating the key operation unit of the remote controller.
JP 2002-204298 A

  By the way, the long press operation of the memo key may be assigned to other recording functions such as setting / canceling message message recording, and may not be assigned to activation of the music playback function.

  In addition, in the above-mentioned Patent Document 1, it is described that when a call is received during music playback, the music playback is interrupted. There are factors that cause various competing sounds (for example, a button confirmation sound and a mail ringing tone), and it is not always appropriate to suspend music playback when these competing sounds occur.

  Furthermore, when not using a remote controller, in order to specify the music to be played, the music input function must be opened to expose the key input section even if the music playback function can be activated in the folded or folded state. There is a problem that must be.

  The present invention has been made under such a background, and an object of the present invention is to provide a mobile phone terminal device that allows more appropriate operation buttons to be used for activation of a music playback function unit.

  Another object of the present invention is to provide a mobile phone terminal device capable of appropriately adjusting music playback sound and competing sound according to circumstances.

  Still another object of the present invention is to provide a mobile phone terminal device that can perform operations such as designation of music while the casing is closed after the music playback function is activated.

  A mobile phone terminal device according to the present invention is a mobile phone terminal device provided with a camera shooting function unit and a music playback function unit, and includes an operation button exposed on the side of the casing. It is shared for activation of the music playback function unit, and selectively activates the camera shooting function unit and the music playback function unit according to different operations on the operation buttons, and the operation button is pressed during operation of the camera shooting function unit. It is used as a shutter button.

  The operation buttons exposed on the side surfaces of the casing are shared by the single button for starting the camera shooting function unit and the music playback function unit due to different operations (for example, the length of time for pressing the operation buttons is different). The Further, the operation button can be used as a shutter button during the operation of the camera photographing function unit. The operation buttons exposed on the side surface of the housing can be always accessed by the user regardless of the shape of the housing. Actually, a shutter button that has been conventionally prepared only for the camera photographing function can be used as the operation button.

  An upper case having a display unit and an operation unit and a lower case having a key input unit are provided, and the display unit and the operation unit are always exposed on the main surface of the upper case, and the upper case is placed in the lower case If the application is applied to a mobile phone terminal device in which the key input unit on the lower housing appears by sliding the upper housing 180 degrees relative to the lower housing from the state where the music playback function is overlaid, Also, by using the operation unit, it is possible to perform operations such as specifying a song without opening the casing.

  When the music playback function unit has a function to continue playback in the background when other functions are used, an event / action accompanied by the generation of other sounds may occur during music playback by the music playback function unit. is there. In such a case, it is preferable to change the control mode of music reproduction in accordance with the event / action.

  For example, when an incoming call is received during music playback by the music playback function unit, the music playback is stopped and a ring tone is sounded. If the user operates the key input unit during music playback by the music playback function unit, music playback is continued and button confirmation sound accompanying key input is suppressed. When an incoming e-mail is received during music playback by the music playback function unit, the music playback is continued as a temporary silence and a mail ringing tone is sounded during that time.

  According to the present invention, an operation button that has been conventionally assigned only to the camera function is shared for starting up the music playback function, so that the function of other existing operation buttons is not hindered, and a new The music playback function can be activated quickly and easily without adding an operation button, and the convenience of the mobile terminal device can be improved.

  The present invention also relates to a mobile phone terminal device in which a key input section on the lower casing appears by rotating the upper casing 180 degrees with respect to the lower casing in a state where the upper casing is overlapped with the lower casing. By applying the, it becomes possible to perform operations such as specifying a song while the housing is closed after the music playback function is activated.

  Furthermore, with respect to competing sounds that can occur during music playback, the music playback control mode has been changed according to the event / action that accompanies the generation of the competing sound, so it is appropriate for each event / action. It is possible to take a music reproduction control mode (stop, continue, silence continuation, etc.).

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 and FIG. 2 are plan views showing a front side appearance of a mobile phone terminal device (also simply referred to as a mobile terminal) 100 to which the present invention is applied. FIG. 1 is a closed state in which upper and lower housings are overlapped, FIG. Indicates an open state in which the upper and lower housings are opened. In this example, the display unit 103 and the operation unit 105 are always exposed on the main surface of the upper housing 102, and the upper housing 102 is mounted on the lower housing from the state where the upper housing 102 is overlaid on the lower housing 202 (FIG. 1). A mobile phone terminal of a type (so-called 180 degree open style type or slide rotation type) in which the key input unit 201 on the lower housing 202 appears by rotating the body 202 by sliding 180 degrees is shown.

  In the closed state shown in FIG. 1, both housings are overlapped with each other so that the back surface of the upper housing 102 overlaps the main surface of the lower housing 202. As clearly shown in FIG. 2, the lower end of the upper casing 102 and the upper end of the lower casing 202 overlap each other, and the upper casing 102 is centered around the hinge portion provided at this position. It slides and rotates clockwise or counterclockwise with respect to the lower housing 202. The rotation axis is in a direction substantially perpendicular to the main surfaces of both housings.

  The display unit 103 occupies most of the area on the main surface of the upper housing 102. The display unit 103 includes a display device such as a liquid crystal or an organic EL, and the display screen is always exposed to the outside. In addition to displaying various types of information on a normal mobile phone terminal, the display unit 103 is also used in this embodiment to display a monitor screen in the camera shooting mode and a music playback screen in the music playback mode.

  A speaker 101 as an ear receiver used at the time of a call is arranged on the upper portion of the display unit 103. In addition, a stereo playback speaker (described later) is also provided.

  An operation unit 105 for performing limited operations is arranged in an area below the display unit 103 of the upper housing 102. The operation unit 105 includes various keys 121 to 126 such as a call key 122, a power / end key 125, a clear key 123, and the input device 110. The input device 110 is a so-called disk-type jog dial, and includes a push button 114, a direction instruction key 113, and a rotating ring 112 arranged concentrically from the center. However, the input device 110 is not limited to a disk-type jog dial, and may be any device that can perform direction instruction and determination operations. A microphone, which is a device that converts sound into an electrical signal, is not shown in the figure, but is provided in the lower portion of the upper housing 102. In the configuration of FIG. 1, even when the upper and lower casings are closed (that is, the key input unit 201 including the numeric keypad of the lower casing 202 is not exposed to the outside), incoming calls and received mails can be confirmed. It is possible to make a call to a party whose telephone number is registered in the internal telephone directory.

  As can be seen from FIG. 2, a key input unit 201 to be pressed is disposed on the main surface of the lower housing 202, and the key input unit 201 is hidden behind the upper housing 102 in the closed state of FIG. 1. . The key input unit 201 includes a numeric keypad and the like (including numerals 0 to 9 as well as symbols * and #).

  FIG. 3 shows a circuit configuration of the mobile phone terminal 100. As shown in this figure, the cellular phone terminal 100 has a power supply circuit unit 251, an operation input control unit 252, an image for a main control unit 250 configured to control the display unit 212 and each unit of the main body. An encoder 253, a camera interface unit 254, an LCD (Liquid Crystal Display) control unit 255, an image decoder 256, a demultiplexing unit 257, a recording / playback unit 262, a modulation / demodulation circuit unit 258, and an audio codec 259 are connected to each other via a main bus 260. In addition, an image encoder 253, an image decoder 256, a demultiplexing unit 257, a modulation / demodulation circuit unit 258, and an audio codec 259 are connected to each other via a synchronization bus 261.

  When the end of call and the power key are turned on by a user operation, the power supply circuit unit 251 activates the cellular phone terminal 100 by supplying power from the battery pack to each unit.

  The cellular phone terminal 100 converts the audio signal collected by the microphone 221 in the audio call mode into digital audio data by the audio codec 259 based on the control of the main control unit 250 including a CPU, ROM, RAM, and the like. The modulation / demodulation circuit unit 258 performs spread spectrum processing, and the transmission / reception circuit unit 262 performs digital / analog conversion processing and frequency conversion processing, and then transmits the result via the antenna 214.

  In addition, the cellular phone terminal 100 amplifies the reception signal received by the antenna 214 in the voice call mode, performs frequency conversion processing and analog-digital conversion processing, performs spectrum despreading processing by the modulation / demodulation circuit unit 258, and performs analog speech by the voice codec 259. After being converted into a signal, it is output via a speaker 224 (corresponding to 101 in FIG. 1). Further, stereo playback sound can be output from the speakers 217r and 217l for music data stored in a storage medium such as a memory stick 223, which will be described later, via the recording / playback unit 262 and the audio codec 259. A signal output terminal 225 for headphones (earphones) is also provided.

  Further, when transmitting an e-mail in the data communication mode, the cellular phone terminal 100 is input by operating the operation key 219 (corresponding to the key input unit 201 in FIG. 2) and the jog dial 222 (corresponding to the input device 110 in FIG. 1). The e-mail text data is sent to the main control unit 250 via the operation input control unit 252.

  The main control unit 250 performs spread spectrum processing on the text data in the modulation / demodulation circuit unit 258, performs digital analog conversion processing and frequency conversion processing in the transmission / reception circuit unit 262, and then transmits the data to a base station (not shown) via the antenna 214. To do.

  On the other hand, when receiving an e-mail in the data communication mode, the mobile phone terminal 100 performs spectrum despreading processing on the received signal received from the base station via the antenna 214 by the modulation / demodulation circuit unit 258 to convert the original text data. After the restoration, it is displayed as an e-mail on the liquid crystal display 218 (corresponding to the display unit 103 in FIG. 1) via the LCD control unit 255.

  Thereafter, the cellular phone terminal 100 can record the received e-mail, downloaded music data, and the like on the memory stick 223 via the recording / playback unit 262 in accordance with the user's operation.

  On the other hand, when transmitting image data in the data communication mode, the cellular phone terminal 100 supplies image data captured by the camera 216 using an image sensor such as a CCD to the image encoder 253 via the camera interface unit 254.

  Incidentally, when not transmitting image data, the mobile phone terminal 100 can directly display the image data captured by the camera 216 on the liquid crystal display 218 via the camera interface unit 254 and the LCD control unit 255.

  The image encoder 253 converts the image data supplied from the camera 216 into encoded image data by compressing and encoding the image data using a predetermined encoding method such as MPEG (Movig Picture Experts Group) 2 or MPEG4, and multiplexes the encoded image data. The data is sent to the separation unit 257. At the same time, the cellular phone terminal 100 sends the sound collected by the microphone 221 during imaging by the camera 216 to the demultiplexing unit 257 via the audio codec 259 as digital audio data.

  The demultiplexing unit 257 multiplexes the encoded image data supplied from the image encoder 253 and the audio data supplied from the audio codec 259 by a predetermined method, and the modulation / demodulation circuit unit 258 spectrums the resulting multiplexed data. The signal is subjected to spreading processing, subjected to digital / analog conversion processing and frequency conversion processing by the transmission / reception circuit unit 262, and then transmitted through the antenna 214.

  On the other hand, when receiving data of a moving image file linked to, for example, a simple homepage in the data communication mode, the cellular phone terminal 100 receives a received signal received from the base station via the antenna 214 by the modulation / demodulation circuit unit 258. The spectrum despreading process is performed, and the multiplexed data obtained as a result is sent to the demultiplexing unit 257.

  The demultiplexing unit 257 separates the multiplexed data into encoded image data and audio data, supplies the encoded image data to the image decoder 256 via the synchronization bus 261, and supplies the audio data to the audio codec. 259.

  The image decoder 256 generates reproduced moving image data by decoding the encoded image data by a decoding method corresponding to a predetermined encoding method such as MPEG2 or MPEG4, and generates the reproduced moving image data via the LCD control unit 255. Accordingly, the moving image data included in the moving image file linked to the simple homepage is displayed, for example.

  At the same time, the audio codec 259 converts the audio data into an analog audio signal, and then supplies the analog audio signal to the speakers 217r and 217l. Thus, for example, the audio data included in the moving image file linked to the simple homepage Played. Also in this case, as in the case of e-mail, the cellular phone terminal 100 can record the data linked to the received simple homepage or the like on the memory stick 223 via the recording / playback unit 262 by the user's operation.

  FIG. 4 shows an appearance of mobile phone terminal 100 according to the present embodiment when closed. This figure is a view of the right side surface of the upper housing 102 as viewed obliquely from above. At this angle, an AV (Audio Visual) button 131, which is an operation button according to the present invention, an earphone terminal portion 132 (in the example shown in the figure, the terminal is hidden by a cover), and macro photography are provided on the right side surface of the upper housing 102. It can be seen that a selection slide switch 133 is provided. The AV button 131 can selectively activate a camera shooting function and a music playback function, and functions as a shutter button during selection of the camera shooting function.

  FIG. 5 shows a camera unit 270 (corresponding to the camera 216 in FIG. 1) provided on the main surface exposed to the outside of the lower housing 202 at all times. The camera unit 270 includes a lens unit 274, a mirror unit 275, a photolight unit 276, and a slide type shielding member 271 that selectively exposes / shields them. FIG. 6 shows a state where the shielding member 271 is slid to shield the lens portion 274 and the like. As shown in FIG. 6, sound outlets 231, 232, 233, and 234 of stereo speakers 217 r and 217 l are provided on both sides of the lower housing 220. Among these, the sound emission ports 233 and 234 are closed when the shielding member 271 is shielded, and are exposed when the shielding member 271 is opened. The sound emission ports 233 and 234 have a function of assisting the sound emission ports 231 and 232 so that sound is emitted also on the main surface side of the lower housing 220. However, in this embodiment, the shielding member 271 is opened. Since the music playback is not performed in the camera photographing mode, the sound outlets 233 and 234 are not affected even if they are blocked. The state (closed or opened) of the shielding member 271 can be detected by a detection means (for example, a switch) not shown. A portion 235 in the lower left part of FIG. 5 indicates a slot for inserting a storage medium (memory stick 223 in this embodiment).

  Hereinafter, the operation of the mobile phone terminal 100 according to the present embodiment will be described.

  FIG. 7 shows an example of processing executed when the AV button 131 is pressed. This process is realized by program control of the main control unit 250. When the AV button 131 is pressed, it is checked whether or not it is in a standby state in which a standby screen is currently displayed (S1). If it is in the standby state, it is checked whether or not the continuous pressing time of the AV button 131 is longer than a predetermined time (for example, 1 second) (so-called “long pressing”) (S4). In this example, if “long press” is entered, the camera shooting mode is entered (S6). If it is not “long press” but “short press”, it shifts to the music playback mode (S5). The correspondence between the long press / short press and both operation modes may be reversed. If it is determined in step S1 that the camera is not in the standby state, it is checked whether the camera photographing mode is currently entered (S2). If it is present, it is determined that the pressing of the AV button 131 is the pressing of the shutter button of the camera photographing function, and the shutter operation is executed (S3). After steps S3, S5, and S6, the original state is restored.

  FIG. 8 shows a state transition after transition from the standby screen to the music playback mode in the present embodiment. When the AV button 131 is pressed for a short time on the standby screen, the screen shifts to the music playback screen. The present embodiment includes three screens, a list display screen, a normal display screen, and a song information display screen as shown in FIGS. 9, 10, and 11, respectively. These details will be described later.

  When the AV button 131 is pressed for a short time on the standby screen, the screen shifts to one music playback screen (a list display screen in the example in the figure). However, the music playback screen that was displayed last time may be stored, and the screen may be shifted directly to the new music playback screen. The three music playback screens are cyclically switched in the order of the list display screen, the normal display screen, and the music display screen by an instruction operation of the user, in this example, by an instruction operation of the “display” button in the screen. In any of the music playback screens, it is possible to return to the previous screen by a specific key, here, the “clear” key 123 or the “short press” of the AV button 131. At this time, if the music is being reproduced, the reproduction is continued. When the end call key 125 is “short-pressed”, the screen returns to the standby screen. At this time, if the music is being reproduced, the reproduction is stopped. When the end call key 125 is “long pressed”, the power is turned off. If music is being reproduced at this time, the reproduction is naturally stopped.

  Table 1 summarizes the operations corresponding to various key operations on such a music playback screen.

  FIG. 9 shows an example of a list display screen. This list display screen is a screen for displaying list information of all the songs to be played back, and is roughly divided into four display areas 910, 920, 930, and 940. The display area 910 includes an icon 911 indicating the strength of a known received radio wave, an icon 913 indicating the remaining battery level, a time display 914, and a storage medium (memory stick 223 in this embodiment) that can be attached to and detached from the portable terminal. An icon 912 indicating the wearing state is displayed. The display area 920 displays an icon 921 indicating the current playback state (FIG. 9 is stopped), a number 922 indicating the song number, and a number 923 indicating the playback time or playback elapsed time (playback time in FIG. 9). . A display area 930 displays a list of all songs stored in the attached storage medium. In the example of the figure, the song number and the title of the song are displayed as a pair. When the number of songs does not fit in the display area 930, it can be handled by scroll display. Although only the song number and the title are displayed in the display area 930 due to the limitation of the display size, the title and the artist may be switched and displayed according to a predetermined operation by the user. The display area 940 is an area in which operation instructions associated with the operation buttons 121 and 124 functioning as the input device 110 of the operation unit 105 and so-called soft keys are displayed. In the example of the figure, in response to the input device 110, various operations such as song selection, playback / stop instruction, song advance, song return, fast forward playback, fast reverse playback, and volume adjustment can be performed. In addition, the “display” button can be used to cyclically switch between the three music playback screens. The “function” button is an operation button for displaying a function menu during reproduction or stop. The function menu includes, for example, operations such as repeat setting for repeatedly playing a specific song (one song or all songs), bass amplification setting for playback sound, and erasing songs (one song or all songs).

  FIG. 10 shows an example of a normal display screen. This screen is a screen for simply displaying song information for one song. This screen shows a normal display screen during playback of a specific song. Elements similar to those shown in FIG. 9 are given the same reference numerals. In place of the display area 930 of the list display screen of FIG. 9, display areas 951 and 952 for displaying the title of the song and the name of the artist, and a display area 953 for displaying an animation during reproduction are provided. The number 923 on this screen indicates the elapsed playback time of the song.

  An icon 912 in the display area 910 indicates that a song is currently being played. An icon 921 in the display area 920 also indicates that a song is being played. The icons 912 and 921 both indicate “reproducing”, but the display area 920 is not displayed during background reproduction, so the icon in the display area 910 is useful.

  The display at the center of the display area 940 is assigned to “volume” adjustment and “stop” operation in correspondence with the reproduction. When the display is switched to the list display screen of FIG. 9 after starting the reproduction of the music, the display area 940 of FIG. 10 is also displayed on the list display screen.

  FIG. 11 shows an example of the song information display screen. This is a screen for displaying the information of the selected song in detail. In this example, the album title, genre, performance time, bit rate, file size, codec type, reproducible start date and reproducible end date and time are displayed. The reproducible start date and time and the reproducible end date and time are data indicating a usable period corresponding to the copyright of the song. Thereby, the user can confirm the period in which the song can be used.

  The present embodiment supports background playback that enables other functions, such as e-mail creation, to be performed in parallel while playing a song. In particular, in this case, the relationship with competing sounds accompanying various events and actions becomes a problem. Such competing sounds are more important than music playback, for example, from the more important ones like telephone ringtones, to the key confirmation sounds that occur when keys are operated (when set to ON). There are even low-quality ones that cannot be dealt with uniformly.

  FIG. 12 is a flowchart of a process for adjusting the relationship between various competing sounds and music reproduction. This process is started when various events and actions occur.

  First, when the event / action is an incoming call and it is necessary to ring a ringtone (or ringtone melody) (S11), the music playback from the speakers 217r and 217l is forcibly stopped (S12). Ring a ringtone (or ringtone melody) (S13). When the earphone is attached, the output to the speakers 217r, 217l, 224 is switched to the earphone. This is because notification of incoming calls is considered more important than music playback. The same action can be taken when a schedule alarm or clock alarm occurs.

  If the event / action is a key operation of the user, the case is opened, or the like, and it is necessary to generate a button confirmation sound or sound effect (S14), the music playback is continued and the button confirmation sound or effect is generated. Generation of sound is suppressed (S16). This is because generation of button confirmation sound and sound effect is considered to be less important than music playback.

  When the event / action is an incoming e-mail and it is necessary to ring the mail ringtone (S17), the music playback is muted (silence: no volume) (S18) and the ringtone for the mail is ringed. (S19). After the ringing of the mail ringing tone is finished, the music playback volume is restored (S20). Notification of incoming mail is considered as important as incoming telephone calls, but the incoming ringing tone is generated continuously while the caller is calling, whereas the incoming e-mail tone is only for a preset time or number of times. This is because it is considered that it is sufficient to temporarily stop the music playback because it ends in a relatively short time by ringing, and it is not necessary to stop the music playback.

  The preferred embodiments of the present invention have been described above, but various modifications and changes other than those mentioned above can be made. For example, specific device structures, processes, and the like are merely examples, and the present invention is not limited to these specific examples. Although the slide rotation type mobile phone terminal has been described as an example, the present invention is not limited to this. For example, the present invention can be applied to a so-called straight type mobile phone terminal. In addition, it can be partially applied to a folding type. Although an example of switching and using three types of music playback screens has been shown, the number of music playback screens is arbitrary. Instead of or in addition to the music playback function unit, a television broadcast playback function unit is provided to selectively activate either of these two or three parties according to different operations on a single operation button. It is also possible to make it.
