DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
[0008]
[Overview of mobile communication terminal]
First, with reference to FIG. 1, the general configuration of a mobile communication terminal according to an embodiment of the present invention will be described.
[0009]
As shown in FIG. 1, the mobile communication terminal 1 according to the embodiment of the present invention includes a display unit 2, an operation input unit 3, an earpiece 4, and a mouthpiece 5 as main components.
[0010]
The display unit 2 is configured by a display device such as an LCD (Liquid Crystal Display) or an EL (ElectroLuminescence) panel, and in accordance with control of a CPU (Central Processing Unit, see FIG. 2) 15 described later, letters, numbers, symbols, Visible display of icons, cursors, images, moving images, etc.
[0011]
The operation input unit 3 is, for example, input of numbers from “0” to “9”, input of kana characters, input of alphabet characters, input of symbols, input instruction of transmission and reception, input of instructions to turn on / off the power A plurality of key buttons 6 are used for operations such as inputting camera function instructions using the camera unit 26 described later. The operation input unit 3 also has a dial (jog dial) 7 used for operations such as moving the cursor displayed on the display unit 2 and scrolling the screen. The earpiece 4 and the mouthpiece 5 are respectively connected to a speaker and a microphone (see FIG. 2), which will be described later, and are used when the user performs a voice call with the other party.
[0012]
[Internal configuration of mobile communication terminal and its basic operation]
Next, with reference to FIG. 2, the internal configuration and the basic operation of the mobile communication terminal 1 will be described. In addition, since the structure and operation | movement of the display part 2 and the operation input part 3 are as above-mentioned, the description is abbreviate | omitted below.
[0013]
In the mobile communication terminal 1 shown in FIG. 2, the microphone 8 connected to the mouthpiece 5 (see FIG. 1) converts the user's call voice and the like into an analog voice signal. The analog audio signal is amplified by an amplifier (not shown) and then input to a DSP (Digital Signal Processor) 9.
[0014]
When an analog audio signal is input, the DSP 9 performs analog / digital (A / D) conversion on the analog audio signal at a predetermined sampling rate. The DSP 9 adds a CRC (Cyclic Redundancy Check) code for each transport block (TB) to the digital audio data obtained by the A / D conversion, and performs channel coding (error correction coding) and interleaving processing. Apply. The transport block is a basic unit of data (a unit in which data is transferred from the MAC (Medium Access Control) layer to the physical layer) to be processed by the physical layer.
[0015]
Further, the DSP 9 performs data modulation processing on the bit sequence after the interleave processing, after adding overhead such as pilot bits for channel determination, and performs in-phase on the phase plane on which data modulation mapping is performed. The quadrature component and the quadrature component are each spread with a spreading code sequence of two layers. The DSP 9 limits the band of the spread chip data series to a predetermined band (5 MHz) with a raised cosine root Nyquist filter, and then converts the chip data series into an analog signal by digital / analog (D / A) conversion. To enter.
[0016]
When an analog signal is input from the DSP 9, the transmitter 10 performs quadrature demodulation on the analog signal, and frequency-converts the quadrature demodulated intermediate frequency signal into a high-frequency signal (2 GHz band RF signal). Then, the transmitter 10 amplifies the high-frequency signal and outputs the amplified high-frequency signal to the duplexer 11 as a transmission signal.
[0017]
The duplexer 11 is an antenna duplexer. That is, the duplexer 11 shares one antenna 12 for the transmission signal and the reception signal, sends the reception signal from the antenna 12 to the reception unit 13, and sends the transmission signal from the transmission unit 10 to the antenna 12. It is composed of a filter circuit having a function.
[0018]
The receiving unit 13 amplifies the high frequency received signal supplied via the antenna 12 and the duplexer 11, and frequency-converts the amplified received signal into an intermediate frequency signal. The receiver 13 linearly amplifies the intermediate frequency signal by automatic gain control, and inputs the linearly amplified intermediate frequency signal to the DSP 9. At this time, the DSP 9 performs quadrature detection on the signal from the receiving unit 13 and A / D converts the in-phase and quadrature component analog signals obtained by the quadrature detection at a predetermined sampling rate. The DSP 9 performs propagation by despreading the in-phase and quadrature components converted into digital values by the A / D conversion using the same spreading code as the spreading code of the received signal after band limiting by the square cosine root Nyquist filter. Time separation is performed into a plurality of multipath components having different delay times.
[0019]
In addition, the DSP 9 performs coherent lake combining of the data of each path separated by time, deinterleaves and channel decodes the data sequence after the coherent lake combining, performs binary data determination, and transmits to the destination terminal. Play the data series. The DSP 9 discriminates the reproduced data series into audio data and other communication data. The voice data is D / A converted by the DSP 9 and further amplified by an amplifier (not shown), and then sent to the speaker 14 built in the earpiece 4 (see FIG. 1). The speaker 14 is driven by the amplified analog audio signal. As a result, the call voice from the terminal of the call partner is emitted from the speaker 14.
[0020]
Further, the DSP 9 analyzes what kind of data the communication data is, and performs processing according to the analysis result. For example, when the communication data is text data, the DSP 9 sends the text data to the CPU 15, and the CPU 15 controls the display of the text data on the display unit 2. For example, when the communication data is compressed image data, the DSP 9 decompresses the compressed image data and sends it to the CPU 15. The CPU 15 controls the display of the image data on the display unit 2. For example, when the communication data is compressed audio data, the DSP 9 expands the compressed audio data and outputs the audio data to the speaker 16 or the speaker 14.

[0032]
[Operation of mobile communication terminal]
[Shooting process]
The mobile communication terminal 1 having the above configuration associates the function realized by the camera unit 26 with the part, scale, and note in the music performance data 19 in addition to the normal shooting mode by operation of the operation input unit 3, A music shooting mode for executing the function of the camera unit 26 associated in parallel with the reproduction processing of the data 19 for use. According to such a music shooting mode, the user can execute a desired camera function at an arbitrary timing by setting a trigger for executing the camera function at an arbitrary position in the music performance data 19, and Self-timer time can be set freely. Hereinafter, the operation of the mobile communication terminal 1 when the user performs shooting processing in the music shooting mode will be described in detail with reference to the flowchart shown in FIG.
[0033]
The flowchart shown in FIG. 3 starts when the user operates the operation input unit 3 to set the mobile communication terminal 1 to the music shooting mode and instruct the execution of the shooting process. This control is performed in step S1. Proceed to Here, when setting the music shooting mode, the user selects the file name of the music performance data 19 to be reproduced, and at the same time functions the camera unit 26 associated with the parts, scales, and notes in the music performance data 19. Set. In the following description, the user selects the scale “do” and “shutter press control function” of the music performance data 19, the scale “re” and “zoom control function”, and the scale “mi” and “white balance control function”. Are associated with each other. The data set in this way is recorded in the setting data 21 of the recording unit 17 by the CPU 15 in a table format as shown in FIG.
[0034]
In the process of step S1, the CPU 15 loads the music performance data 19 selected by the user into the RAM 25, and reads information on the part, scale, and notes from the loaded music performance data 19. Thereby, the process of step S1 is completed, and the control proceeds from the process of step S1 to the process of step S2.
[0035]
In the process of step S2, the CPU 15 reproduces the music performance data 19 using the information read in the process of step S1 according to the reproduction program 23. Thereby, the process of step S2 is completed, and the control proceeds from the process of step S2 to the process of step S3.
[0036]
In step S3, the CPU 15 determines whether or not the reproduced music performance data 19 (in this case, the scale) is associated with the function of the camera unit 26 according to the shooting program 24 with reference to the setting data 21. To do. As a result of the determination, if the reproduced music performance data 19 is not associated with the function of the camera unit 26, the CPU 15 advances the control from step S3 to step S5. On the other hand, if it is determined that the reproduced music performance data 19 is associated with the function of the camera unit 26, the CPU 15 advances the control from step S3 to step S4.
[0037]
In the process of step S4, the CPU 15 controls the camera unit 26 to execute the function associated with the reproduced music performance data 19 in accordance with the shooting program 24. Specifically, in this example, since the user has set the setting data 21 as shown in FIG. 4 described above, the CPU 15 causes the camera unit to press the shutter when the scale “do” is reproduced. 26 is controlled. Similarly, the CPU 15 controls the camera unit 26 so that zoom processing is performed when the scale “R” is reproduced, and white balance is adjusted when the scale “M” is reproduced. Thereby, the process of step S4 is completed, and the control proceeds from the process of step S4 to the process of step S5.
[0038]
In the process of step S5, the CPU 15 determines whether or not there is unreproduced music performance data 19 loaded in the RAM 25. If the result of determination is that there is unreproduced music performance data 19, this control returns from the process of step S5 to the process of step S2. On the other hand, when there is no unreproduced music performance data 19, the series of control ends. In the above description, the user associates the scale in the music performance data 19 with the function of the camera unit 26, but the user may associate the part or note in the music performance data 19 with the function of the camera unit 25.
[0039]
[Data creation process for music performance]
The above control is performed using the music performance data 19 stored in the recording unit 17 and the ROM 22, but the user creates the music performance data for performing the above control and uses the created data. The above control may be performed. According to such a configuration, as shown in FIG. 4 described above, in a state where the scale of the music performance data 19 is associated with the function of the camera unit 25, for example, the user can select “do”, “le”, “do”. When the music performance data 19 composed of the three continuous scales is created, the three camera functions of “shutter”, “zoom”, and “shutter” are performed in accordance with the reproduction of the created music performance data 19. It can be executed continuously and automatically, eliminating the need to repeatedly operate the operation input unit 3.
[0040]
Hereinafter, with reference to the flowchart shown in FIG. 5, the flow of processing when the user creates the music performance data 19 for performing the above control will be described. In the following description, it is assumed that the user creates the music performance data 19 by operating the mobile communication terminal 1, but for music performance using an information processing device such as a personal computer or a PDA (Personal Digital Assistant). The data 19 may be created, and the created music performance data 19 may be loaded into the recording unit 17 of the mobile communication terminal 1.
[0041]
The flowchart shown in FIG. 5 is started when the user operates the operation input unit 3 to instruct the CPU 15 to execute the application program for realizing the music performance data creation function. This creation process is performed in step S11. Proceed to processing. The processing of the CPU 15 shown below is realized by the CPU 15 executing an application program.
[0042]
In the process of step S11, the CPU 15 displays a selection screen for selecting a part for registering a sound source on the display unit 2, and the user operates the operation input unit 3 in response to the display of the selection screen. Then, a desired part is selected from the displayed selection screen. Thereby, the process of step S11 is completed, and the creation process proceeds from the process of step S11 to the process of step S12.
[0043]
In the process of step S12, the CPU 15 displays a selection screen for selecting a sound source to be registered in the selected part on the display unit 2, and the user operates the operation input unit 3 in response to the display of the selection screen. Then, a desired sound source is selected from the displayed selection screen. Thereby, the process of step S12 is completed, and the creation process proceeds from the process of step S12 to the process of step S13.
[0044]
In the process of step S <b> 13, the CPU 15 displays the part where the sound source is registered on the display unit 2, and the user operates the operation input unit 3 to display the part on the display unit 2 as the part is displayed. Select a part for inputting scales and notes from the selected parts. Thereby, the process of step S13 is completed, and the creation process proceeds from the process of step S13 to the process of step S14.
[0045]
In the process of step S14, the CPU 15 displays an interface screen for inputting scales and notes on the display unit 2, and the user operates the operation input unit 3 in response to the display of the interface screen. Enter the scale and note of the part in the interface screen. Thereby, the process of step S14 is completed, and the creation process proceeds from the process of step S14 to the process of step S15.
[0046]
In the process of step S15, the CPU 15 monitors whether or not the user has operated the operation input unit 3 to perform a scale and note input completion operation. If the input completion operation has been performed, this creation process is performed in step S15. The process proceeds to the process of step S17. On the other hand, when the user does not perform the input completion operation and inputs a new scale and note, the CPU 15 inserts a delimiter between the input note data as the process of step S16, and performs this creation process. The process returns to the process of step S14 from the process of S16. The delimiter is a delimiter for enabling each musical note constituting the music performance data 19 to be individually searched. By this delimiter, the CPU 15 interprets information indicated by each musical note and associates it with each musical note. The functions of the camera unit 26 can be executed.
[0047]
In the process of step S17, the CPU 15 displays a confirmation message such as “Do you want to input a scale or a note in another part?” On the display unit 2, and the user operates the operation input unit 3 to display other messages. When an instruction to input a scale or a note to the part is given, the creation process returns from the process of step S17 to the process of step S13. On the other hand, if the user does not instruct other parts to input scales and notes and requests completion of the creation process, the CPU 15 advances the creation process from step S17 to step S18. .
[0048]
In the process of step S <b> 18, the CPU 15 records data set and input by the user in the storage unit 17 as music performance data 19. Thereby, a series of creation processing ends.
[0049]
[Effect of the embodiment]
As is clear from the above description, according to the mobile communication terminal of this embodiment, the functions realized by the camera unit 26 are associated with the parts, scales, and notes in the music performance data 19 and are associated with each other. Since the function of the camera unit 26 can be executed in parallel with the reproduction processing of the music performance data 19, the user can easily use the camera function without operating the key buttons.
[0050]
Further, according to the mobile communication terminal of this embodiment, a trigger for executing the camera function is set at an arbitrary position in the music performance data 19, and this trigger is detected during the reproduction processing of the music performance data 19. Therefore, the user can use camera functions other than pressing the shutter even from a distant position.
[0051]
Furthermore, according to the mobile communication terminal of this embodiment, since the camera function can be controlled simultaneously with the end of the reproduction of the music performance data 19, the user can perform music performance data with different reproduction times. By appropriately selecting 19, the self-timer time can be arbitrarily changed.
