  Referring to FIG. 1, the mobile terminal 10 includes a processor 20, sometimes called a CPU or a computer, a key input device 22, and the like. The processor 20 controls the radio communication circuit 14 corresponding to the W-CDMA (sometimes referred to as 3GSM) system and outputs a call signal. The output call signal is transmitted from the antenna 12 and transmitted to the mobile communication network including the base station. When the other party performs a response operation, a call ready state is established.

  When a call end operation is performed by the key input device 22 after shifting to a call ready state, the processor 20 controls the wireless communication circuit 14 to transmit a call end signal to the other party. Then, after transmitting the call end signal, the processor 20 ends the call process. The processor 20 also ends the call process when a call end signal is received from the other party first. Furthermore, the processor 20 also ends the call process when a call end signal is received from the mobile communication network regardless of the call partner.

  When a call signal from a call partner is captured by the antenna 12 while the mobile terminal 10 is activated, the wireless communication circuit 14 notifies the processor 20 of an incoming call. The processor 20 vibrates the portable terminal 10 with a vibration device (not shown), and outputs a ringing sound from a speaker (not shown) to inform the user that the call signal is being received (calling state). Notice. Then, the processor 20 controls the display driver 24 to display the caller information transmitted from the call partner together with the call signal on the display 26.

  In the call ready state, the following processing is executed. The modulated audio signal (high frequency signal) sent from the other party is received by the antenna 12. The received modulated audio signal is subjected to demodulation processing and decoding processing by the wireless communication circuit 14. The obtained received voice signal is output from the speaker 18. On the other hand, the transmission voice signal captured by the microphone 16 is subjected to encoding processing and modulation processing by the wireless communication circuit 14. Then, the generated modulated audio signal is transmitted to the other party using the antenna 12 as described above.

  The mobile terminal 10 also includes a power supply circuit 44 that supplies power to the entire system based on the voltage of the lithium ion battery 46 that is a secondary battery. When the power supply circuit 44 supplies power based on the voltage of the lithium ion battery 46 to the entire system, it is referred to as a power-on state. Similarly, when the power supply circuit 44 does not supply power based on the voltage of the lithium ion battery 46 to the entire system, it is referred to as a power-off state. The power supply circuit 44 is activated when a power-on operation is performed by the key input device 22 in the power-off state, and is stopped when a power-off operation is performed by the key input device 22 in the power-off state. Further, even in the power-off state, the power supply circuit 44 is activated when the charging of the lithium ion battery 46 is detected, and stops in response to the completion of the charging of the lithium ion battery 46. A state in which the lithium ion battery 46 is charged is referred to as a charged state. Further, charging means that the terminals Ta and Tb are connected to an external power source and supplied with electric power from the external power source, whereby electric energy is stored in the lithium ion battery 46.

  The terminal Ta is a + terminal and the terminal Tb is a-terminal. Further, the charging circuit 44 detects charging by measuring the current value of the lithium ion battery 46. Further, when charging is detected by the charging circuit 44, the processor 20 causes an LED (not shown) to emit light.

  A projector 32 is connected to the processor 20, and the projector 32 can execute a projector function. For example, the user projects the image data stored in the flash memory 28 or the RAM 30 by executing the projector function.

  The GPS control circuit 34a and the GPS antenna 34b function as position information acquisition means, and the processor 20 can acquire the current position information by the GPS control circuit 34a and the GPS antenna 34b. For example, when an operation for obtaining position information is performed by the user, the processor 20 activates the GPS control circuit 34a and receives a GPS signal transmitted from a GPS satellite by the GPS antenna 34b. Then, the processor 20 acquires the latitude and longitude of the current position from the received GPS signal.

  Further, the portable terminal 10 can execute a camera function. When an operation for executing the camera function is performed by the key input device 22, the camera control circuit 36a and the image sensor 36b are caused to function as photographing means to execute the camera function. To do.

  For example, an optical image of the object scene is irradiated to the image sensor 36b, and a light receiving element corresponding to, for example, UXGA (1600 × 1200 pixels) is arranged in the imaging area of the image sensor 36b. In the imaging area, photoelectric conversion is performed. Thus, a charge corresponding to the optical image of the object scene, that is, a UXGA raw image signal is generated.

  When the camera function is executed, the processor 20 activates an image sensor driver built in the camera control circuit 36a to display a real-time moving image of the subject, that is, a through image, on the display 26, and performs an exposure operation and designation. The image sensor driver is instructed to perform a charge readout operation corresponding to the readout area.

  The image sensor driver performs exposure of the imaging surface of the image sensor 36b and reading of the charges generated by the exposure. As a result, a raw image signal is output from the image sensor 36b. The output raw image signal is input to the camera control circuit 36a. The camera control circuit 36a performs processes such as color separation, white balance adjustment, and YUV conversion on the input raw image signal, and YUV conversion is performed. Format image data is generated. Then, YUV format image data is input to the processor 20. At this time, the camera control circuit 36a focuses on the object scene by controlling the focus lens 36c.

  The YUV format image data input to the processor 20 is temporarily stored in the RAM 30 by the processor 20. Further, the stored YUV format image data is provided from the RAM 30 to the display driver 24 via the processor 20. At the same time, the processor 20 issues a thinning readout command to the display driver 24. Then, the display driver 24 outputs YUV format image data to the display 26 at 30 fps in accordance with the thinning-out readout command issued from the processor 20. Thereby, a low resolution (for example, 320 × 240 pixels) through image representing the object scene is displayed on the display 26.

  In the YUV format image data, Y means luminance, U means a color difference obtained by subtracting luminance from blue, and V means a color difference obtained by subtracting luminance from red. That is, YUV format image data is composed of luminance signal (Y) data, blue color difference signal (U) data, and red color difference signal (V) data.

  Further, when a photographing operation is performed by the key input device 22, the processor 20 executes a main photographing process. That is, the processor 20 performs predetermined signal processing on the UXGA raw image signal output from the image sensor 36b, temporarily stores it in the RAM 30, and instructs the I / F 40 to perform recording processing on the memory card 42. The I / F 40 reads the image data from the RAM 30 through the processor 20 and records it in the memory card 42 as an image file including the read image data. Furthermore, the processor 20 outputs a sound notifying that the main photographing process is being executed from a speaker (not shown). The memory card 42 is detachable, and can be accessed by the I / F 40 when inserted in a slot (not shown).

  The user can select WQVGA (240 × 400 pixels) and VGA (640 × 480 pixels) in addition to UXGA as the size of image data to be captured. If the size of the selected image data is WQVGA, the image data is not stored in the memory card 42 but is recorded in the flash memory 28. Furthermore, the camera function can be executed in a moving image shooting mode for shooting a moving image.

  In addition, the mobile terminal 10 has a TV viewing function, and when an operation for executing the TV viewing function is performed by the key input device 22, an image by TV broadcasting is displayed on the display 26. Specifically, the TV tuner 38a extracts a broadcast signal corresponding to the selected channel from the broadcast signal received by the TV antenna 38b. Further, the TV tuner 38a performs a process such as demodulation on the extracted broadcast signal to generate a demodulated signal. Further, the TV tuner 38a outputs a demodulated signal to the mobile terminal 10, and the mobile terminal 10 performs a decoding process based on the MPEG system on the demodulated signal to form a video signal. The formed video signal is output to the display 26, and the display 26 displays a video of the selected channel by TV broadcasting.

  The antenna 12 that receives the calling signal and the caller information functions as receiving means, and the RAM 30 functions as storage means. The speaker 18 is sometimes called an audio output device, and the display 26 is sometimes called a display device. Furthermore, the mobile terminal 10 can also execute a moving image playback function for playing back moving images and a slide show function for playing back a plurality of image data continuously. Then, the mobile terminal 10 can perform data communication with a mail server (not shown) and send / receive mail by the mail function.

  FIG. 2 is an illustrative view showing a block diagram showing an electrical configuration of the projector 32. Referring to FIG. 2, a projector 32 includes a mirror control circuit 50 to which a control signal is input from the processor 20, a laser control circuit 52 to which a video signal is input, red (R) color, green (G) color, A laser oscillator 54 capable of outputting blue (B) laser light, a condensing lens 56, and a MEMS (Micro Electro Mechanical Systems) mirror 58 including a mirror and an actuator for driving the mirror are included. For example, the laser oscillator 54 adjusts the intensity of each color based on the control of the laser control circuit 52, and outputs the laser light of each color to the condenser lens 56. The output red, green, and blue laser beams are condensed into one laser beam by the condensing lens 56 and output to the mirror of the MEMS mirror 58. The condensed laser light is reflected by the mirror of the MEMS mirror 58 and output to an external screen. At this time, the mirror control circuit 50 drives the MEMS mirror 58 based on the control signal from the processor 20 so that the focused laser beam becomes an image corresponding to the video signal.

Further, the user can end the correction for the trapezoidal distortion by operating the “next” soft key 64.

  The soft keys 64 and 66 are operated by the user when a key corresponding to the soft keys 64 and 66 is pressed on the key input device 22.

  With reference to FIG. 8B, when the soft key 66 is operated on the distortion correction screen, the luminance correction screen is displayed in the function display area 62. When the brightness correction is displayed, the brightness in the projected image can be corrected. For example, the user increases the brightness of the projected image by operating the upward direction of the cross key 22d, and decreases the brightness by operating the downward direction. Then, the user can return to the distortion correction screen by operating the “return” soft key 68. Further, the user can end the correction of the brightness by operating the “next” soft key 70.

  Referring to FIG. 8C, when soft key 70 is operated on the brightness correction screen, a function setting screen is displayed in function display area 62. On the function setting screen, it is possible to set a specific function that is executed simultaneously with the projector function. For example, on the function setting screen, a first function key 72 for setting a slide show function, a second function key 74 for setting a TV viewing function, a third function key 76 for executing a moving image playback function, and execution A fourth function key 78 that does not set the function to be displayed is displayed. Then, the user can return to the brightness correction screen by operating the “return” soft key 80. The user can end the initial setting by selecting one of the first function key 72, the second function key 74, the third function key 76, and the fourth function key 78.

  As for the first function key 72 to the fourth function key 78, any one of the function keys is temporarily selected when the cross key 22d is operated. When a menu key or the like for confirming temporary selection is operated in a state where any one function key is temporarily selected, the selection of the function key is confirmed.

  For example, the user can select the first function key 72 by temporarily selecting the first function key 72 with the cross key 22d and operating the menu key. When the first function key 72 is selected, the projector function and the slide show function are executed at the same time, so that a photographic image stored in the flash memory 28 or the memory card 42 is projected on the screen.

  Referring to FIG. 8D, when the initial setting of the projector function is completed, the result of the initial setting is displayed on display 26. That is, as the trapezoidal distortion correction value, the upper side is displayed as “U: 50”, the lower side as “D: 0”, the left side as “L: 0”, and the right side as “R: 0”. In addition, “+10” is displayed as the luminance correction value. Further, “not set” indicating that the fourth function key 78 has been selected is displayed as the execution function setting. The results of these initial settings are stored in the RAM 30 as setting information.

  The user can return to the function setting screen by operating the “return” soft key 82. Further, the user can erase the screen on which the result of the initial setting is displayed by operating the “confirm” soft key 84. Then, the result of the initial setting is automatically deleted even if a certain time (for example, 5 seconds) elapses.

  In this embodiment, position information (30 ° 00'37.XX "N, 135 ° 45'05.YY" E) is displayed as a result of the initial setting, and the position information is also stored in the RAM 30 as setting information. The The initial setting is performed by the cross key 22d, but may be performed by the first side key 22a, the second side key 22b, and the third side key 22c. For example, on the distortion display screen, the user corrects the upper side of the projected image by single pressing the first side key 22a, and corrects the lower side by single pressing the second side key 22b. Further, the right side is corrected by continuously pressing the first side key 22a, and the lower side is corrected by continuously pressing the second side key 22b. Then, the user operates the “next” soft key 66 by single pressing the third side key 22c, and operates the “stop” soft key 64 by continuously pressing the third side key 22c. To do. In order to improve operability, a plurality of side keys may be provided.

  Here, a case where the initial setting process is interrupted will be described in detail. First, when the mobile terminal 10 is removed from the cradle Cr during the initial setting, the initial setting process is temporarily suspended. Then, when the mobile terminal 10 is placed again on the cradle Cr, the initial setting process is resumed. At this time, the display 26 displays a confirmation pop-up for confirming whether the initial setting is resumed in a state where the state before the temporary suspension is retained, or whether the state before the temporary suspension is reset and the initial setting is resumed.

  Next, also when a call signal is received during the initial setting, the initial setting process is temporarily interrupted. For example, when the user responds to the incoming call and the call is terminated, a standby image representing the standby state is displayed on the display 26. Then, when the mobile terminal 10 is again placed on the cradle Cr, the initial setting process is resumed. When the initial setting process is resumed, a confirmation pop-up is displayed as described above.

  On the other hand, if the user does not respond to the incoming call and the call signal is interrupted, the confirmation pop-up is not displayed on the display 26, and the initial setting process is performed in a state where the state before the temporary suspension is maintained. Is resumed. Information indicating that the incoming call was not answered is displayed on the display 26. For example, referring to FIG. 9A, if the user does not respond to the call, a pop-up P indicating the caller information is displayed as information indicating that the user has not responded to the call.

  Referring to FIG. 9B, missed call icon 86a may be displayed in status display area 60 as information indicating that the call has not been answered. Further, when several seconds have elapsed after the pop-up P is displayed, the pop-up P disappears and the missed call icon 86a is displayed instead.

  In another embodiment, when a call signal is received during the initial setting, the caller is notified that the user cannot respond with the answering function, and a call end signal is transmitted. Also good. That is, the initial setting is prioritized over the incoming call, and the user is only notified that the call signal has been received. For example, when a call signal is received during initial setting, the caller information is notified to the user by a pop-up P (see FIG. 9A). At this time, the pop-up P is deleted when an arbitrary key is operated, and when the display is deleted, the missed call icon 86a is displayed in the status display area 60 as shown in FIG. 9B.

  Further, in other embodiments, the missed call icon 86a may be displayed suddenly without displaying the pop-up P. In addition, when an incoming mail is received, an incoming mail icon 86 b is displayed in the status display area 60. The missed call icon 86a and the incoming mail icon 86b continue to be displayed until the user confirms the missed call or mail.

  As described above, when the initial setting is performed by the user, the projection image shown in FIG. 7 is corrected for trapezoidal distortion and the like, and the projection image as shown in FIG. 10 is projected onto the screen. That is, the distortion of the lower side is corrected, and the lengths of the upper side and the lower side become substantially the same length.

  Referring to FIG. 11, the setting information is recorded in RAM 30 as data constituting a setting table. In the setting table, columns of name, distortion correction, luminance, execution function, and position information are set, and one setting information is recorded for each row. For example, in the row where “setting 1” is recorded as the setting name in the name column, “U: 50, D: 0, L: 0, R: 0” is stored in the distortion correction column. “+10” is stored in the luminance column. Furthermore, “-” indicating that nothing is set is stored in the execution function column, and “30 ° 00'37.XX” N, 135 ° 45′05. YY "E" is stored.

  “Setting 1” stored in the name column can be arbitrarily changed by the user, and may be changed to “home”, for example. A row in which “default” is recorded in the name column indicates setting information used when the screen Sc (see FIG. 6) that can be mounted on the cradle Cr is used.

  Here, when the mobile terminal 10 is placed on the cradle Cr, setting information is read from the RAM 30, and an image is projected based on the read setting information. Specifically, when the mobile terminal 10 is placed on the cradle Cr, the processor 20 acquires the current position information, and the position information included in the setting information stored in the RAM 30 has a correlation with the current position information. If so, the setting information is read out.

  Then, the processor 20 causes the display 26 to display a confirmation screen for confirming whether or not to execute the projector function. For example, referring to FIG. 12, display 26 includes a character string “Do you want to execute the projector function?”, An accept key 88 for executing the projector function, and a reject key for canceling the execution of the projector function. 90 is displayed.

  Here, when the user selects the consent key 88, the projector function is executed, and the projection image is corrected based on the read setting information. Further, if it is initially set to execute a specific function, the processor 20 executes the specific function simultaneously with the projector function. For example, if the slide show function is set as a specific function, the processor 20 executes the projector function and the slide show function simultaneously. That is, the user can project an image of an arbitrary function on the screen simply by placing the mobile terminal 10 on the cradle Cr.

  If the initial setting is not performed so as to execute a specific function, that is, if the fourth function key 78 is selected on the execution function setting screen, the portable terminal 10 is executed until immediately before being placed on the cradle Cr. The function is executed simultaneously with the projector function. For example, when the mobile terminal 10 that executes the TV viewing function is placed on the cradle Cr, the mobile terminal 10 projects an image of the TV program on the screen.

  If the user selects the reject key 90 on the confirmation screen, the execution of the projector function is canceled and nothing is projected on the screen. Further, even if the acceptance key 88 and the rejection key 90 are not operated and the first predetermined time (for example, 10 seconds) elapses, the execution of the projector function is canceled. Further, the consent key 88 may be always selected so that the display of the confirmation screen is omitted.

  If there is no correlation between the position information included in the setting information stored in the RAM 30 and the current position information, the processor 20 causes the display 26 to display a selection screen. For example, referring to FIG. 13, an initial setting key 92, a setting information key 94, and a default key 96 are displayed on the selection screen.

  When the initial setting key 92 is selected by the user, a distortion correction screen shown in FIG. 8A is displayed, and initial setting for the projection image is started. That is, by selecting the initial setting key 92, the user can perform initial setting according to the location where the projector function is executed, and store the result of the initial setting in the mobile terminal 10 as setting information. For example, when the user performs the initial setting at home and then causes the projector function of the mobile terminal 10 to be executed at the company, the user can newly create setting information for the company. Referring to FIG. 11, when a new initial setting is made by the user, it is recorded in the line next to “setting 1”.

  When the setting information key 94 written as “setting 1” is selected by the user, setting information corresponding to “setting 1” is read from the setting table. That is, the projection image is corrected based on the setting information corresponding to setting 1. This is because there is an error in the position information based on the GPS signal, and there is no correlation between the position information included in the setting information stored in the RAM 30 and the current position information due to the error even in the same place. There is. Therefore, in this embodiment, when there is no correlation in the position information, the position information is displayed so as to be selectable. Thereby, the user can easily read the setting information even in a situation where the cradle Cr cannot be correctly identified.

  In this embodiment, if the position information error is within a predetermined distance (for example, 50 m), the processor 20 determines that the position information has a correlation. That is, if the position information is approximately the same (substantially matches), it is determined that there is a correlation. In addition, when a second predetermined time (for example, 15 seconds) elapses after the selection screen is displayed, the selection screen is deleted.

  Further, when the default key 96 is selected by the user, setting information corresponding to “default” is read from the setting table. That is, setting information suitable for the screen Sc is read out.

  Thus, the position information is used as identification information for identifying a plurality of cradle Cr. When the user installs the cradle Cr at a plurality of locations, the mobile terminal 10 identifies each cradle Cr by the position information. It becomes possible to do. That is, the user can install the cradle Cr at a plurality of locations and execute the projector function with settings suitable for each location. In addition, the developer of the mobile terminal 10 can identify a plurality of cradle Cr by using highly versatile position information.

  The cradle Cr may include an electric circuit that outputs an identification signal that can identify itself. That is, the mobile terminal 10 may identify each of the plurality of cradle Cr by the identification signal from the cradle Cr.

  FIG. 14 is an illustrative view showing a memory map 300 of the RAM 30. Referring to FIG. 14, a memory map 300 of RAM 30 includes a program storage area 302 and a data storage area 304. A part of the program and data is read from the flash memory 28 all at once or partially and sequentially as necessary, stored in the RAM 30, and then executed by the processor 20.

  The program storage area 302 stores a program for operating the mobile terminal 10. Programs for operating the mobile terminal 10 include a slide show program 310, a TV viewing program 312, a moving image playback program 314, an initial setting program 316, a projector setting program 318, a projector program 320, and the like. The slide show program 310 is a program for displaying photographic image data stored in the flash memory 28 or the memory card 42 at regular intervals. The TV viewing program 312 is a program for viewing a TV program based on broadcast signals received by the TV tuner 38a and the TV antenna 38b. The moving image reproduction program 314 is a program for reproducing a moving image stored in the flash memory 28 or the memory card 42. The moving image data may be downloaded from a network, or may be shot in a moving image shooting mode using a camera function.

  The initial setting program 316 is a program for correcting the image projected by the projector 32. The projector setting program 318 is a program for reading setting information, and is executed when the mobile terminal 10 is placed on the cradle Cr. The projector program 320 is a program for controlling the projector 32.

  In addition, although illustration is abbreviate | omitted, the program for operating the portable terminal 10 also includes the program for performing a telephone call, the program for acquiring position information, etc.

  In the data storage area 304, a function information buffer 330, a correction value buffer 332, and a position information buffer 334 are provided. The data storage area 304 stores setting table data 336, image data 338, and moving image data 340, and is also provided with an initial setting flag 342, a charging flag 344, a GUI display counter 346, and the like.

  The function information buffer 330 is a buffer that temporarily stores function information of functions that have been executed until immediately before the mobile terminal 10 is placed in the cradle Cr. For example, when the mobile terminal 10 is placed in the cradle Cr while the TV viewing function is being executed, information indicating the TV viewing function is temporarily stored in the function information buffer 330. The correction value buffer 332 is a buffer that temporarily stores a correction value obtained by executing the initial setting program 316. The position information buffer 334 is a buffer for temporarily storing position information obtained from the GPS signal. The setting table data 336 is data of the setting table shown in FIG. 11 and includes setting information.

  The image data 338 is data read by the slide show program 310, for example, photographic image data stored in the flash memory 28. The moving image data 340 is data read by the moving image reproduction program 340.

  The initial setting flag 342 is a flag for determining whether the initial setting of the projector function has been performed even once. For example, the initial setting flag 342 is composed of a 1-bit register. When the initial setting flag 342 is turned on (established), a data value “1” is set in the register. On the other hand, when the initial setting flag 342 is turned off (not established), a data value “0” is set in the register.

  The charge flag 344 is a flag for determining whether or not charging of the lithium ion battery 46 is detected by the power supply circuit 44. Note that the configuration of the charge flag 344 and the initial setting flag 342 is the same, and thus detailed description thereof is omitted.

  The GUI display counter 346 is a counter for measuring the time after the GUI is displayed on the display 26.

  Although not shown, the data storage area 304 stores GUI data composed of an image and a character string for displaying a GUI, voice data output in response to an incoming call, and the like. In addition, a counter and a flag necessary for the operation of the mobile terminal 10 are also provided.

  The processor 20 includes an initial setting process shown in FIG. 15 and a projector setting process shown in FIG. 16 under the control of an RTOS (Real-time Operating System) such as “Linux (registered trademark)” and “REX”. Process these tasks in parallel.

  FIG. 15 is a flowchart of the initial setting process. When the mobile terminal 10 is placed on the cradle Cr and the charge flag 344 is turned on, the processor 20 displays a distortion correction screen in step S1. For example, a distortion correction screen as shown in FIG. Subsequently, in step S3, it is determined whether or not the cross key 22d has been operated. That is, it is determined whether or not the cross key 22d is operated to correct the trapezoidal distortion.

  If “NO” in the step S3, that is, if the cross key 22d is not operated, the process of the step S3 is repeatedly executed. On the other hand, if “YES” in the step S3, that is, if the cross key 22d is operated, the distortion correction value is changed in a step S5 according to the operation direction. For example, in step S 5, if the upward direction is operated by the cross key 22 d, the correction value for the upper side is changed, and the correction value is temporarily stored in the correction value buffer 332. The correction result in step S5 is reflected in the projection image. That is, the user can confirm the result of correction performed by the cross key 22d with his / her own eyes.

  Subsequently, in step S7, it is determined whether or not a completion operation has been performed. That is, it is determined whether or not the soft key 60 shown in FIG. If “NO” in the step S7, that is, if the soft key 60 is not operated, the process returns to the step S3, and if “YES”, that is, if the soft key 60 is operated, the process proceeds to a step S9.

  In step S9, a brightness correction screen is displayed. For example, the brightness correction screen shown in FIG. Subsequently, in step S11, it is determined whether or not the cross key 22d has been operated. That is, it is determined whether or not an operation for correcting the luminance of the projected image has been performed. If “NO” in the step S11, that is, if the operation for correcting the luminance is not performed, the process in the step S11 is repeatedly executed.

  On the other hand, if “YES” in the step S11, that is, if an operation for correcting the luminance is performed, the luminance correction value is changed in a step S13 according to the direction of the operation. For example, if a downward operation is performed on the cross key 22d, a correction for decreasing the luminance is performed, and the correction value is temporarily stored in the correction value buffer 332. Note that, in the brightness correction screen shown in FIG. 8B, the operation in the left-right direction is not instructed, so the operation in the left-right direction may be invalidated, the left direction corresponds to the lower direction, and the right direction is changed. You may make it respond | correspond to an upward direction. In step S15, it is determined whether the operation is a completion operation. That is, it is determined whether or not the soft key 62 shown in FIG. If “NO” in the step S15, that is, if the completion operation is not performed, the process returns to the step S11. If “YES” in the step S15, that is, if a completion operation is performed, the process proceeds to a step S17.

  In step S17, a function setting screen is displayed. For example, the function setting screen shown in FIG. Subsequently, in step S19, it is determined whether or not a key has been selected. That is, it is determined whether any one key from the first function key 72 to the fourth function key 78 is selected. If “NO” in the step S19, that is, if any key is not selected, the process of the step S19 is repeatedly executed. On the other hand, if “YES” in the step S19, for example, if the first function key 72 corresponding to the slide show function is selected, the function information is set according to the key selected in the step S21. For example, if the first function key 72 is selected, the function information of the slide show function is temporarily stored in the correction value buffer 332.

  Subsequently, in step S23, the current position information is acquired. That is, the GPS control circuit 34a is activated to acquire position information. The acquired position information is stored in the position information buffer 334. Subsequently, in step S25, the result of the initial setting is stored as setting information. That is, the distortion correction value, the luminance correction value, and the function information stored in the correction value buffer 332 and the position information stored in the position information buffer 334 are stored in the setting table data 336. Subsequently, in step S27, the setting result is displayed. For example, the setting information is displayed on the display 26 as shown in FIG.

  Subsequently, in step S29, it is determined whether or not the initial setting flag 342 is on. That is, it is determined whether or not the initial setting has been performed. If “YES” in the step S29, that is, if the initial setting has been performed, the initial setting process is ended and the process returns to the main routine (for example, the projector setting process). On the other hand, if “NO” in the step S29, that is, if the initial setting has never been performed, it is determined whether or not to execute the projector function in a step S31. That is, the confirmation screen shown in FIG.

  If “NO” in the step S31, for example, if the rejection key 90 is operated or the value of the GUI display counter 346 becomes equal to or longer than the first predetermined time, the initial setting process is ended. On the other hand, if “YES” in the step S31, for example, if the consent key 88 is operated, a specific function is executed in a step S33. For example, if the setting information includes function information indicating the slide function, the slide show function is executed. If the function information is not included in the setting information, the setting information is executed based on the function information stored in the function buffer 330 being executed. For example, when step S33 is executed in a state where the function information indicating the TV viewing function is stored in the in-execution function buffer 330, the TV viewing function is executed again.

  Subsequently, the projector function is executed in step S35. That is, the projector program 320 is executed, and an image corresponding to the program being executed is projected on the screen. For example, if the TV viewing function has already been executed, the TV program is projected on the screen. Subsequently, in step S37, the initial setting flag 342 is turned on, and the initial setting process ends. That is, in step S37, since the initial setting is completed, the initial setting flag 342 is turned on.

  When the “Cancel” soft key 64 (see FIG. 8A) is operated, the initial setting process is terminated. Further, when the off of the charging flag 344 is detected or a call signal is received, the initial setting is temporarily suspended. When the initial setting process is temporarily interrupted, the processing state is temporarily stored in the RAM 30 and continues to be held in the RAM 30 until the process is resumed. Although not shown in FIG. 15, when one of the “return” soft keys 68, 80, 82 (see FIGS. 8B to 8D) is operated, the previous setting screen is displayed. To return to.

  The processor 20 that executes the processes of steps S3, S13, S21, and S23 functions as an initial setting unit, and the processor 20 that executes the process of step S25 functions as an initial setting storage unit. The processor 20 that executes the process of step S33 functions as a function execution unit, and the processor 20 that executes the process of step S35 functions as a control unit.

  FIG. 16 is a flowchart of the projector setting process. In addition, since the process of step S57-S61 is the same as the process of step S31-S35 (refer FIG. 15), detailed description is abbreviate | omitted.

  If the charge flag 344 is turned on and the initial setting flag 342 is turned on, the processor 20 acquires the current position information in step S51. That is, position information based on the GPS signal is acquired and stored in the position information buffer 334. Subsequently, in step S53, it is determined whether or not the position information has a correlation. That is, it is determined whether or not there is a correlation between the position information included in each setting information and the position information stored in the position information buffer 334. If “NO” in the step S53, that is, if there is no correlation between the two pieces of position information, the process proceeds to a step S63. The processor 20 that executes the process of step S51 functions as identification information acquisition means.

  On the other hand, if “YES” in the step S53, that is, if there is a correlation between the two position information, the setting information including the correlated position information is read in a step S55, and the process proceeds to the step S57. For example, referring to FIG. 11, if there is a correlation between the position information stored in position information buffer 334 and the position information included in the setting information of setting 1, the position information corresponding to setting 1 is determined in step S55. Read out.

  In step S57, it is determined whether or not to execute the projector function. If “NO” in the step S57, the projector setting process is ended. On the other hand, if “YES” in the step S57, a specific function is executed in a step S59. Subsequently, in step S61, the projector function is executed, and the projector function is terminated. The processor 20 that executes the process of step S61 also functions as a control unit.

  If there is no correlation between the two pieces of position information, a selection screen is displayed in step S63. That is, as shown in FIG. 13, a plurality of setting information is selectively displayed on the display 26, and an initial setting key 92 for performing initial setting is also displayed. The processor 20 that executes the process of step S63 functions as a display unit.

  Subsequently, in step S65, it is determined whether or not the initial setting is made. That is, it is determined whether or not the initial setting key 92 has been selected. If “YES” in the step S65, that is, if the initial setting key 92 is selected, an initial setting process is executed in a step S67. That is, the initial setting process shown in FIG. 15 is executed. The processor 20 that executes the process of step S67 also functions as an initial setting unit.

  On the other hand, if “NO” in the step S65, that is, if the initial setting key 92 is not selected, it is determined whether or not the setting information is selected in a step S69. For example, referring to FIG. 13, it is determined whether setting information key 94 or default key 96 has been selected. If “YES” in the step S69, that is, if setting information is selected, the setting information selected in the step S71 is read, and the process proceeds to a step S57. For example, if the setting information key 94 shown in FIG. 13 is selected in step S71, setting information corresponding to setting 1 is read.

  If “NO” in the step S69, that is, if the setting information is not selected, it is determined whether or not a time-out occurs in a step S73. For example, when a selection screen is displayed on the display 26 in step S63, the time is measured by the GUI display counter 346. In step S73, it is determined whether or not the second predetermined time is measured by the GUI display counter 346. That is, in the projector setting process, the processes of steps S65, S69, and S73 are repeatedly executed until the selection screen is displayed on the display 26 and operated by the user.

  If “NO” in the step S73, that is, if a predetermined time has not elapsed since the selection screen is displayed, the process returns to the step S65. On the other hand, if “YES” in the step S73, that is, if a predetermined time elapses after the selection screen is displayed, the projector setting process is ended.

  The processor 20 that executes the process of step S55 functions as a first reading unit, and the processor 20 that executes the process of step S71 functions as a second reading unit. The processor 20 functioning as the first reading unit or the second reading unit is sometimes called a reading unit.

  As can be seen from the above description, the mobile terminal 10 includes the projector 32 that projects an image. When the user places the mobile terminal 10 on the cradle Cr and makes initial settings such as trapezoidal distortion and brightness for the projected image, the initial setting result is stored in the RAM 30 as setting information. Further, when the charging of the lithium ion battery 46 is detected by the power supply circuit 44, the processor 20 acquires current position information and reads setting information including position information correlated with the position information from the RAM 30. Then, the processor 20 corrects the projected image based on the read setting information, and causes the projector 32 to project the image.

  Thus, since the preset correction value is stored and the image is projected based on the correction value, the user can use the projector function without taking the trouble of correction.

  The projector 32 may be a projector using an LED as a light source. In this case, the setting correction information includes a focus correction value. Further, in the initial setting of the projector function, not only correction of trapezoidal distortion, luminance, and focus, but also correction of contrast, color, and the like may be performed.
