[0044] 3, the display control ECU 28 of the vehicle display device 10 includes a CPU (Central Processing Unit: processor) 40A, a ROM (Read Only Memory) 40B, a RAM (Random Access Memory) 40C, a storage 40D, a communication interface (communication I / F) 40E, and an input / output interface (input / output I / F) 40F. Each component is connected to each other via a bus 42 so as to be able to communicate with each other.

[0045] The CPU 40A is a central processing unit that executes various programs and controls each part. That is, the CPU 40A reads a program from the ROM 40B or the storage 40D, and executes the program using the RAM 40C as a working area. The CPU 40A controls each of the above components and performs various arithmetic processing according to the program recorded in the ROM 40B or the storage 40D.

[0046] The ROM 40B stores various programs and various data. The RAM 40C temporarily stores programs or data as a working area.

In this embodiment, the ROM 40B or the storage 40D stores programs for performing display processing, various data, and the like.

[0047] The communication I / F 40E is an interface for the vehicle display device 10 to communicate with a server and other devices (not shown), and uses standards such as Ethernet (registered trademark), LTE, FDDI, and Wi-Fi (registered trademark).

[0048] The input / output I / F 40F is connected to the first display unit 24 and a head-up display device (HUD) 44. The head-up display device 44 projects an image onto the display area V2 of the second display unit 26.

[0049] The input / output I / F 40F is also connected to a system bus 43 arranged in the vehicle 12. The system bus 43 is connected to a switch control device 45, an engine control device 46, a driving mode control device 47, a vehicle control device 48, an in-vehicle device 49, and the like.

[0050] The switch control device 45 is connected to various switches serving as selection means and setting means, including the steering switch 30, and controls inputs from the various switches. In this embodiment, the switch control device 45 detects the operation state of the steering switch 30 and outputs the detected state to the display control ECU 28 via the system bus 43.

[0051] Various sensors for controlling the operation of the engine are connected to the engine control device 46, and in this embodiment, an engine speed sensor 46A for detecting the engine speed is connected. The engine control device 46 controls the operation of the engine based on the detection results of the various sensors including the engine speed sensor 46A. The engine control device 46 also transmits a signal indicating the engine speed detected by the engine speed sensor 46A to the input / output I / F 40F.

[0052] The running mode control device 47 controls the running mode of the vehicle 12. The vehicle 12 has a plurality of running modes set in advance, and the plurality of running modes in this embodiment are configured, for example, with three running modes: a normal mode, an eco mode, and a sports mode. The normal mode allows driving in a state with good fuel efficiency while bringing out power performance, and is set in normal times. The eco mode is a low-fuel consumption running mode that allows driving in a state in which fuel efficiency performance is prioritized over power performance compared to the normal mode. The sports mode is a high-power running mode that allows driving in a state in which power performance is prioritized over fuel efficiency compared to the normal mode. The running mode immediately after starting the vehicle 12 is set to the normal mode. The running mode control device 47 transmits a signal indicating the selected running mode to the input / output I / F 40F based on, for example, a driving mode selection operation by the steering switch 30.

[0053] The vehicle control device 48 is equipped with various control ECUs such as a vehicle control ECU for vehicle control including driving control, a steering control ECU for steering control, a braking control ECU for braking control, and a gear shift control ECU for controlling the transmission.

[0055] (Functional configuration of the display control ECU 28) The display control ECU 28 uses the above hardware resources to realize various functions. The functional configuration realized by the display control ECU 28 will be described with reference to FIG.

[0056] 3, the display control ECU 28 includes, as functional components, an acquisition unit 52 and a display control unit 54. Each functional component is realized by the CPU 40A reading and executing a program stored in the ROM 40B or the storage 40D.

[0057] The acquisition unit 52 acquires a physical quantity related to the running state of the vehicle 12. In this embodiment, the acquisition unit 52 acquires the current engine speed of the vehicle 12 as the physical quantity related to the running state of the vehicle 12. As an example, the acquisition unit 52 in this embodiment acquires a signal indicating the engine speed transmitted by the engine control device 47 via the input / output I / F 40F to acquire the current engine speed.

[0058] The display control unit 54 acquires information corresponding to the running state and operation state of the vehicle 12 via the system bus 43, and displays an image corresponding to the acquired information as a display screen in the display area V1 of the first display unit 24, and also displays the image in the display area V2 of the second display unit 26 via the HUD 44. In the display control ECU 28, when the vehicle 12 is in a steady state, the information to be displayed in the display area V1 of the first display unit 24 and the format of the image for displaying the information are determined.

[0059] As shown in FIG. 4, an image 60 as a display screen displayed in the display area V1 of the first display unit 24 is substantially rectangular. The image 60 is an image showing the engine speed, and a tachometer image 62 for showing the engine speed is arranged in the center. The tachometer image 62 has narrow arc-shaped scale bars 64 arranged in the circumferential direction. The scale bar 64 shows the range of engine speed from 0 to 8000 rpm in stages using numbers 66 from "1" to "8". Although not shown in the figure, the number "×1000" is displayed in the display area V1, and the value obtained by multiplying the number indicated in the scale bar 64 by 1000 is the engine speed.

[0060] Also, a colored numerical bar (bar) 68 indicating the current engine RPM is arranged along the scale bar 64, and the right end of the numerical bar 68 extends according to the engine RPM with the left end in the circumferential direction being 0 rpm, thereby displaying the engine RPM. That is, the value indicated by the right end of the numerical bar 68 in the circumferential direction multiplied by 1000 is the current engine RPM. Also, a passing area 68B is displayed in a gradation from the center of the arc constituting the numerical bar 68 to the end in the radial direction of the numerical bar 68, which is displayed in a gradation such that the tip side 68A is emphasized as it moves clockwise from 0 rpm in the circumferential direction. The passing area 68B also includes the numerical bar 68, and the numerical bar 68 is also displayed in a gradation such that the tip side 68A is emphasized as it moves clockwise from 0 rpm in the circumferential direction. In this embodiment, the numerical bar 68 is displayed in a more emphasized manner in the passing area 68B than in other areas.

[0061] In this embodiment, as an example, the display control unit 54 displays the gradation such that the tip side 68A is emphasized by darkening the color and increasing the brightness as the rpm moves clockwise from 0 rpm in the circumferential direction. However, the present invention is not limited to this, and the above-mentioned emphasis may be achieved only by darkening the color, or by increasing the brightness, or any other method may be used as long as the tip side 68A can be emphasized.

[0062] Moreover, in the image 60, the center portion is a shift display area 60A, in which the shift position of the transmission is displayed, and the display is changed by changing the shift position of the transmission. Furthermore, in the image 60, the upper side of the shift display area 60A is a vehicle speed display area 60B, in which a numerical value corresponding to the vehicle speed of the vehicle 12 is displayed. In this embodiment, the shift display area 60A and the vehicle speed display area 60B are, as an example, rectangular areas indicated by dashed lines in the figure.

[0063] In addition, in the image 60, a rectangular display area 60C is disposed below the shift display area 60A, and when the display control unit 54 receives information or an information image relating to an event to be notified from the vehicle control device 48 of the vehicle 12 or each in-vehicle device 49, etc., the display control unit 54 selects a display screen to be displayed in the display area 60C from among the multiple display screens based on the received information, and displays the selected display screen in the display area 60C. The multiple display screens are stored in, for example, the storage 40D as image data representing each display screen.

[0064] Examples of the display screens include drive information for providing traffic information, road information, etc. received via the communication I / F 40E, drive information for providing fuel efficiency information, etc. of the vehicle 12, an energy monitor for providing information indicating the relationship between tires, a battery, and energy, and an audio status screen for providing the operation status of the audio. The display control unit 54 switches between these display screens and displays them in the display area 60C. The display control unit 54 can also switch between the display screens and display them based on, for example, an operation of the steering switch 30. In FIG. 4, an energy monitor is displayed in the display area 60C as an example.

[0065] In this embodiment, the display control unit 54 changes the display mode of the numerical values ​​66 from "1" to "8" based on the current engine RPM of the vehicle 12 acquired by the acquisition unit. Specifically, the change in the display mode in the display area V1 is performed by, for example, storing a plurality of image data configured in advance with a plurality of layouts and display modes in the storage 40D, and the display control unit 54 acquires corresponding image data from the plurality of image data stored in the storage 40D, and displays a display screen based on the acquired image data in the display area V1.

[0066] The display control unit 54 displays the numeric bar 68 so that the right end of the numeric bar 68 gradually extends or gradually shrinks up to a value obtained by dividing the current engine speed by 1000. At this time, the display control unit 54 changes the display mode of the numeric value 66 according to the position of the right end of the numeric bar 68. For example, it is assumed that the acquisition unit 52 acquires 4200 rpm as the current engine speed of the vehicle 12. In this case, the display control unit 54 gradually extends the numeric bar 68 in the circumferential direction from the numeric value 66 side of "0" to the position of [4.2]. At this time, the display control unit 54 displays the luminance of the numeric value 66 included in the value indicated by the right end of the numeric bar 68 higher than that of the other numeric values ​​66. In other words, the tone of the numeric value 66 included in the value indicated by the right end of the numeric bar 68 is increased.

[0067] The display control unit 54 then highlights the closest numerical value 66 when the right end of the numerical value bar 68 passes by, more than the other numerical values ​​66. Here, the current position of the right end of the numerical value bar 68 is taken as position R, and the rotation speeds through which position R passes before the engine rotation speed reaches 4200 rpm are taken as examples of 3300 rpm, 3700 rpm, and 4000 rpm.

[0068] As the position R passes 3300 rpm, as shown in FIG. 4, the display control unit 54 causes the position R to pass the position "3.3" between the numerical value "3" 66 and the numerical value "4" 66 on the scale bar 64. At this time, since "3.3" is closer to "3" than "4", the display control unit 54 displays the numerical value "3" 66 with emphasis more than the other numerical values ​​66. In this embodiment, the display control unit 54 displays the numerical value "3" 66 larger than the other numerical values ​​66. For example, when the numerical values ​​66 other than the numerical value "3" 66 are displayed in a small size, the numerical value "3" 66 is displayed in a medium size.

[0069] Also, when passing 3700 rpm, as shown in FIG. 5, the display control unit 54 passes the position R at "3.7" between the numerical value 66 of "4" and the numerical value 66 of "3" on the scale bar 64. At this time, since "3.7" is a numerical value closer to "4" than "3", the display control unit 54 displays the numerical value 66 of "4" more emphatically than the other numerical values ​​66. In this embodiment, the display control unit 54 displays the numerical value 66 of "4" larger than the other numerical values ​​66. For example, when the numerical values ​​66 other than the numerical value 66 of "4" are displayed in small size, the numerical value 66 of "4" is displayed in medium size. At this time, the display control unit 54 makes the size of the numerical value 66 of "3" smaller than when the position R passed the position of "3.3". In other words, the size of the numerical value 66 of "3" is returned to the original small size.

[0070] Also, when passing 4000 rpm, as shown in FIG. 6, the display control unit 54 causes the position R to pass the numerical value "4" 66 of the scale bar 64. At this time, the display control unit 54 displays the numerical value "4" 66 more emphatically than the other numerical values. In this embodiment, the display control unit 54 displays the numerical value "4" 66 larger than the other numerical values ​​66, but displays the numerical value "4" 66 even larger than when the position R passes "3.2" or "3.7" as described above. That is, when the numerical values ​​66 other than the numerical value "4" 66 are displayed in small size, the numerical value "4" 66 is displayed in large size. In the same manner, when the position R passes 1000 rpm, 2000 rpm, and 3000 rpm, the display control unit 54 displays the numerical value "1" 66, the numerical value "2" 66, and the numerical value "3" 66 in large size similar to the numerical value "4" 66.

[0071] Then, when the rotation speed reaches 4200 rpm, as shown in FIG. 7, the display control unit 54 causes the position R to reach the position "4.2" between the numerical value "5" 66 and the numerical value "4" 66 on the scale bar 64. At this time, since "4.2" is a numerical value closer to "4" than "5", the display control unit 54 displays the numerical value "4" 66 with emphasis more than the other numerical values ​​66. In this embodiment, the display control unit 54 displays the numerical value "4" 66 larger than the other numerical values ​​66. For example, when numerical values ​​other than the numerical value "4" 66 are displayed in small size, the numerical value "4" 66 is displayed in medium size. At this time, the display control unit 54 makes the numerical value "4" 66 smaller than the size when the position R passed the position of "4". In other words, the size of the numerical value "4" 66 is returned to medium size from large size.

[0072] In this way, the display control unit 54 changes the size of the numerical value 66 from small to medium as the position R approaches each numerical value 66, and changes it to large when each numerical value 66 is reached. Then, when each numerical value 66 is passed, the size is changed from large to medium, and further changed from medium to small. Note that, in the above, the case where the position R moves clockwise, i.e., the number of rotations increases, has been described, but the display control unit 54 also performs similar control when the position R moves counterclockwise, i.e., the number of rotations decreases. However, when the number of rotations decreases, i.e., when the position R moves counterclockwise, the display control unit 54 displays the luminance of the numerical value 66 that is not included in the value indicated by the right end of the numerical value bar 68 lower than that of the other numerical values ​​66. That is, the tone of the numerical value 66 that is not included in the value indicated by the right end of the numerical value bar 68 is lowered.

[0073] (Display processing) Next, the vehicle display control process executed in the display control ECU 28 will be described with reference to the flowcharts shown in Figures 8A and 8B. This display control process is executed by the CPU 40A reading out a display control program from the ROM 40B or the storage 40D, and developing and executing the program in the RAM 40C. The following process is started after an instruction to turn on the display screen of the display control ECU 28 is given.

[0074] As shown in FIG. 8A, in step S11, the display control ECU 28 turns on the display screen (display area V1) of the first display unit 24 and the head-up display device 44 (display area V2).

[0075] Next, the acquisition unit 52 acquires the current engine RPM in step S12. Then, the display control unit 54 changes the display manner of the numeric bar 68 and the numeric value 66 displayed in the display area V1 based on the engine RPM acquired by the acquisition unit 52 in step S13. Specifically, the display control unit 54 displays the numeric bar 68 such that the right end of the numeric bar 68 gradually extends up to a value obtained by dividing the current engine RPM by 1000. At this time, the display control unit 54 changes the display manner of the numeric value 66 according to the position R of the right end of the numeric bar 68. Specifically, the tone of the numeric value 66 included in the value indicated by the position R is raised, and the size of the numeric value 66 is changed according to the position R for display.

[0076] Specifically, in step S14, the display control unit 54 determines whether the position R is the numerical value "M" 66, where M is an integer such as 1, 2, etc. In step S14, if the position R is the numerical value "M" 66 (step S14; YES), the display control unit 54 displays the numerical value "M" 66 in a large size as described above in step S15.

[0077] On the other hand, if the position R is not the numerical value 66 of "M" in step S14 (step S14; NO), the display control unit 54 determines in step S16 whether the position R is closer to the numerical value 66 of "M" than the numerical value 66 of "M-1" or "M+1". If the position R is closer to the numerical value 66 of "M" than the numerical value 66 of "M-1" or "M+1" in step S16 (step S16; YES), the display control unit 54 displays the numerical value 66 of "M" in a medium size as described above in step S17.

[0078] Furthermore, in step S16, if the position R is not closer to the numerical value 66 of "M" than to the numerical value 66 of "M-1" or "M+1" (step S16; NO), the display control unit 54 determines in step S18 whether the position R is closer to the numerical value 66 of "M-1" or "M+1" than to the numerical value 66 of "M". In step S18, if the position R is closer to the numerical value 66 of "M-1" or "M+1" than to the numerical value 66 of "M" (step S16; YES), the display control unit 54 displays the numerical value 66 of "M" in a small size as described above in step S19.

[0079] Also, in step S18, if the position R is not closer to the numerical value 66 of "M-1" or "M+1" than to the numerical value 66 of "M" (step S18; NO), the CPU 40A transitions to step S14 and repeats the processes from step S14 onward.

[0080] After the display control unit 54 performs each display in steps S15, S17, and S19, the display control unit 54 determines in step S20 whether or not position R is located at the number of rotations acquired in step S12, as shown in Fig. 8B. If position R is not located at the number of rotations acquired in step S12 in step S20 (step S20; NO), the CPU 40A shifts the process to step S13 as shown in Fig. 8A, and repeats the processes in and after step S13 until position R is located at the number of rotations acquired in step S12.

[0081] On the other hand, as shown in Fig. 8B, in step S20, if the position R is located at the rotation speed acquired in step S12 (step S20; YES), the CPU 40A determines in step S21 whether or not there is an instruction to turn off the display screen. If there is no instruction to turn off the display screen (step S21; NO), the CPU 40A shifts the process to step S12 and repeats the processes from step S12 onwards. On the other hand, if there is an instruction to turn off the display screen (display area V1) of the first display unit 24 and the head-up display device 44 (display area V2) in step S22, and ends the series of processes.

[0082] In this way, until the display screen is turned off, the display control ECU 28 changes the display mode of the numeric bar 68 and the numeric values ​​66 based on the current engine speed acquired by the acquisition unit 52 and displays them in the display area V1.

[0083] (Action and effect) Next, the effects of this embodiment will be described.

[0084] In the display control ECU 28 as a vehicle display control device according to this embodiment, the display mode of the numerical value 66 in the display area V1, which numerically displays a predetermined range of the engine speed of the vehicle 12 as a physical quantity related to the vehicle running state, is changed based on the current engine speed of the vehicle 12 acquired by the acquisition unit 52. Therefore, since it is possible to change the display mode to display more necessary information, the user can visually recognize necessary information without being aware of it even in an analog display mode.

[0085] In the display control ECU 28 as a vehicle display control device according to this embodiment, the display control unit 54 enlarges the numerical value 66 that is closest to the current engine RPM of the vehicle 12 acquired by the acquisition unit 52. Therefore, more necessary information can be displayed enlarged, so that the user can visually recognize necessary information without being aware of it even in an analog display mode.

[0086] In the display control ECU 28 as a vehicle display control device according to this embodiment, the display control unit 54 displays the numerical value 66 through which the current engine RPM of the vehicle 12 acquired by the acquisition unit 52 passes larger than other numerical values ​​66 at the time when the RPM passes. Therefore, since the numerical value 66 through which the current engine RPM of the vehicle 12 acquired by the acquisition unit 52 passes can be displayed larger, the user can visually recognize intermediate values ​​as the current engine RPM increases or decreases.

[0087] In the display control ECU 28 as a vehicle display control device according to this embodiment, the display control unit 54 continuously displays the engine RPM of the vehicle 12 from the minimum value within a predetermined range to the current engine RPM using a numeric bar 68. Therefore, the area passed through in the predetermined area displayed in stages by the numeric values ​​66 is covered by the numeric bar 68, so that the current numeric value indicated by the right end (tip) of the numeric bar 68 can be easily understood.

[0088] In the display control ECU 28 serving as a vehicle display control device according to this embodiment, the display control unit 54 displays the numeric bar 68 with gradation so that the right end side (tip side) is emphasized. Specifically, in a passing area 68B including the numeric bar 68, the gradation is displayed so that the tip side 68A is emphasized. Therefore, since the right end side (tip side) of the numeric bar 68 is emphasized by the gradation, the current numeric value indicated by the right end side (tip side) of the numeric bar 68 can be made easier to understand.

[0089] Furthermore, since the vehicle display device 10 according to this embodiment includes the first display unit 24 having the display area V1 and the display control ECU 28, the same actions and effects as those of the display control ECU 28 described above can be obtained.

[0090] Furthermore, since the vehicle 12 according to this embodiment includes the vehicle display device 10, the same actions and effects as those of the above-mentioned display control ECU 28 can be obtained, similarly to the vehicle display device 10.

[0091] In addition, the vehicle display control method and the vehicle display control program according to this embodiment also provide the same functions and effects as those of the display control ECU 28 described above.

[0092] In the embodiment described above, the display control unit 54 displays the gradation such that the tip side 68A is emphasized by making the color darker and increasing the brightness as the rpm increases clockwise from 0 rpm in the circumferential direction, but the present invention is not limited to this, and the gradation display may not be used. Also, only the numerical bar 68 may be displayed without displaying the passing area 68B.

[0093] In the above embodiment, the display control unit 54 highlights the corresponding numerical value 66 by displaying the corresponding numerical value 66 larger than the other numerical values ​​66, but the present invention is not limited to this. For example, the corresponding numerical value 66 may be displayed in a color that stands out more than the other numerical values, or may be displayed in a flashing manner, or other suitable changes may be made.

[0094] In the above embodiment, the acquisition unit 52 acquires the engine speed of the vehicle 12, and the vehicle 12 is a vehicle equipped with an engine (reciprocating engine) as a driving source for traveling, but the present invention is not limited to this. For example, when the vehicle 12 is a fuel cell electric vehicle (FCEV) or an electric vehicle (BEV) or the like, the acquisition unit 52 can acquire the power of a motor mounted on the vehicle 12 as a physical quantity related to the vehicle traveling state. In this case, the image 60 is an image showing the power of the motor, and an image for showing the power of the motor is arranged in the center. In this image, a narrow scale bar in an arc shape and a range of the power of the motor are displayed in stages by numerical values, as in the above embodiment.

[0095] Furthermore, the acquisition unit 52 may acquire the current vehicle speed of the vehicle 12 as a physical quantity related to the vehicle driving state, regardless of the type of the vehicle 12. In this case, the image 60 is an image showing the vehicle speed, and an image for showing the vehicle speed is arranged in the center. In addition, this image shows a narrow arc-shaped scale bar and a range of the vehicle speed in steps represented by numerical values, similar to the above embodiment.

[0096] The acquisition unit 52 may acquire at least one of the RPM of the engine of the vehicle 12, the power of the motor of the vehicle 12, and the vehicle speed of the vehicle 12 as the physical quantity related to the vehicle driving state, and may acquire two or all of them. In this case, a plurality of images 60 can be displayed in the display area V1 according to the number of the physical quantities acquired by the acquisition unit 52. As described above, in the present invention, since the physical quantity related to the vehicle driving state is at least one of the RPM of the engine of the vehicle 12, the power of the motor of the vehicle 12, and the vehicle speed of the vehicle 12, it is possible to support various vehicles such as a fuel cell vehicle, an electric vehicle, a hybrid vehicle (HEV: Hybrid Electric Vehicle), and a plug-in hybrid vehicle (PHEV: Plug-in Hybrid Electric Vehicle).

[0097] In the above embodiment, the display screens displayed by the display control unit 54 are illustrated in FIGS. 4 to 7 as examples, but the present invention is not limited to this, and different layouts can be used as necessary.

[0098] 9, the display area V1 may be displayed by dividing a predetermined range of a physical quantity related to a vehicle driving state into steps using numerical values. That is, the scale bar 64 and the numerical value bar 68 may be divided at a predetermined interval by a gap 60D. In this case, since the predetermined range of the physical quantity is divided and displayed, it is possible to easily visually recognize the quantity indicated by the numerical value 66 within the predetermined range. Note that only the scale bar 64 may be divided.

[0099] In the above embodiment, the scale bar 64 and the numerical bar 68 are configured in an arc shape, but the present invention is not limited to this. As shown in FIG. 10, an image 70 in a sports mode may be displayed as a display screen displayed in the display area V1 of the first display unit 24. The image 70 is an image showing the engine speed, and a meter image 72 for showing the engine speed is arranged in the upper center. The meter image 72 has linear, narrow scale bars 74 arranged in the horizontal direction. The scale bar 74 shows the range of engine speed from 0 to 8000 rpm in stages using numerical values ​​76 from "1" to "8". Although not shown, the number "×1000" is displayed in the display area V1, and the value obtained by multiplying the numerical value indicated in the scale bar 74 by 1000 is the engine speed.

[0100] Also, a colored numerical bar (bar) 78 indicating the current engine RPM is disposed along the scale bar 74, and the left end of the numerical bar 78 is set to 0 rpm and the right end of the numerical bar 78 extends in accordance with the engine RPM to display the engine RPM. That is, the current engine RPM is calculated by multiplying the value indicated by the right end of the numerical bar 78 by 1000. Even when the scale bar 74 and the numerical bar 78 are displayed in a straight line, the display control unit 54 can change the display mode of the numerical value 76 based on the current engine RPM acquired by the acquisition unit 52, in the same manner as in the above embodiment.

[0101] Furthermore, the number and shapes of each operation switch and each function changeover switch are not particularly limited and may be changed as appropriate.

[0102] Furthermore, in the above embodiment, the display control unit 54 causes the image 60 or the image 70 to be displayed in the display region V1, but the present invention is not limited to this, and the image may be displayed in the display region V2.

[0103] In addition, various processors other than the CPU may execute each process executed by the CPU 40A shown in FIG. 2 by reading the software (program) in this embodiment. In this case, examples of the processor include a PLD (Programmable Logic Device) such as an FPGA (Field-Programmable Gate Array) whose circuit configuration can be changed after manufacture, and a dedicated electric circuit such as an ASIC (Application Specific Integrated Circuit) which is a processor having a circuit configuration designed exclusively for executing a specific process. Each process may be executed by one of these various processors, or may be executed by a combination of two or more processors of the same or different types (for example, a plurality of FPGAs, a combination of a CPU and an FPGA, etc.). The hardware structure of these various processors is, more specifically, an electric circuit that combines circuit elements such as semiconductor elements.

[0104] Furthermore, each program described in the present embodiment may be provided in a form recorded on a recording medium such as a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM (Digital Versatile Disc Read Only Memory), a USB (Universal Serial Bus) memory, etc. Furthermore, the programs may be provided in a form downloaded from an external device via a network.

[0105] Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and it is of course possible to implement the present invention in various other modified forms without departing from the spirit and scope of the present invention.
