(About the structure of the information display apparatus 1 which concerns on embodiment of this invention)
The configuration of the information display device 1 according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram of the main part of the information display device 1. As shown in FIG. 1, the information display device 1 includes a GPS (Global Positioning System) receiving unit 10, a state detecting unit 11, a storage unit 12, a display unit 13, an operation unit 14, a raindrop detecting unit 15, an audio output unit 16, And a control unit 17. The information display device 1 has a function as a PND.

  Note that the droplet detection unit in the claims corresponds to the raindrop detection unit 15. The display form control unit referred to in the claims corresponds to the control unit 17.

  The GPS receiver 10 measures the position of the information display device 1 as a PND by receiving a signal from a GPS satellite (not shown).

  The state detection unit 11 senses the operation of the information display device 1 as a PND by a gyro sensor, an acceleration sensor (not shown) or the like, and corrects its own position measured by the GPS.

  The storage unit 12 includes a memory (internal and / or external), an HDD (Hard Disc Drive), a flash memory, and the like, and stores map information, point information, text fonts, and the like. The storage unit 12 can also store user-preferred data such as music and images.

  The display unit 13 displays a map, guidance display, characters, images, moving images, and the like by drive control of the control unit 17, and includes a liquid crystal display element or an organic EL (Electro Luminescence) display element. Further, the display unit 13 may be such that a transparent plate such as a glass plate or an acrylic plate is disposed on the surface of a liquid crystal display element or an organic EL display element. Alternatively, the display unit 13 may be a plate in which symbols or characters are arranged instead of the above-described transparent plate, and the information displayed on the liquid crystal display element or the organic EL display element can be visually recognized from the outside. Anything is fine.

  The operation unit 14 is a user interface for the user to operate the information display device 1, and includes a touch panel superimposed on the display unit 13 and switches or buttons other than the touch panel. The operation unit 14 may be either a touch panel or a switch or button other than the touch panel.

  The raindrop detection unit 15 is a sensor that is attached to the housing of the information display device 1 and detects waterdrops, for example. This sensor has, for example, two electrodes arranged at a narrow interval, and outputs when a water droplet adheres between the two electrodes to cause conduction between the two electrodes. This sensor is preferably covered with a protective cover (not shown) so that a user's finger or the like does not touch accidentally. It is preferable that the protective cover does not hinder the ingress of liquid into the sensor.

  Alternatively, the raindrop detection unit 15 monitors the input status of the touch panel of the operation unit 14. For example, the raindrop detection unit 15 determines that the raindrop is a raindrop when a touch at the same position is detected for a certain period of time or longer due to the raindrop adhering to the touch panel. In addition, as a method of distinguishing the operation with the user's finger or the like and the attachment of raindrops, for example, in the case of touching the touch panel with the user's finger or the like, there are at most several places touched at the same time. On the other hand, when the touch on the touch panel reaches a large number of locations, it may be determined that raindrops are attached.

  Alternatively, the raindrop detection unit 15 examines in advance a pattern of a change in the input status on the touch panel when the raindrop falls on the touch panel, and stores this pattern in the storage unit 12. Thereby, the raindrop detection unit 15 may determine that the raindrop is falling when the input state of the actual touch panel is similar to this pattern. Also in this case, as described above, as a method of distinguishing the operation by the user's finger or the like and the attachment of the raindrop, for example, in the case of touching the touch panel by the user's finger or the like, there are at most several places touched at the same time. is there. On the other hand, when the touch on the touch panel reaches a large number of locations, it may be determined that raindrops are attached.

  The touch panel system may be any system such as an ultrasonic surface acoustic wave system, an image recognition system, a resistive film system, or a capacitance system.

  Moreover, you may provide separately the sensor equivalent to the touch panel of the operation part 14 as a sensor which detects the water drop mentioned above.

  The audio output unit 16 outputs an audio signal to the digital audio data output from the control unit 17 using a digital / analog conversion unit (not shown), an audio amplification unit (not shown), and a speaker (not shown). To do. As a result, an operation sound or guidance sound related to the operation of the information display device 1 or route guidance is output, and further, a music reproduction sound stored in the storage unit 12 is also output.

  The control unit 17 controls each unit described above, and operates the information display device 1 as a PND in the embodiment of the present invention. That is, the control unit 17 has various basic functions for performing navigation. For example, the control unit 17 is composed of a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an HDD and / or a flash memory, and the like according to a control program previously written in the ROM. It has a function of guiding the user to a destination set by the user based on information from the receiving unit 10, the state detecting unit 11, and the like.

(About operation | movement of the information display apparatus 1)
Next, operation | movement of the control part 17 of the information display apparatus 1 is demonstrated with reference to FIG. FIG. 2 is a flowchart for explaining the operation of the control unit 17. The flowchart in FIG. 2 is an operation limited to the operation related to the display mode change of the display unit 12 among the operations of the control unit 17.

  START: When the power source of the information display device 1 is turned on, the control unit 17 proceeds to the process of step S1.

  Step S <b> 1: The control unit 17 determines whether or not a signal corresponding to detection of water droplets in the raindrop detection unit 15 is input. That is, the control part 17 transfers to the process of step S2, when the signal corresponding to the detection of the water drop in the raindrop detection part 15 is input (Yes in step S1). On the other hand, the control part 17 repeatedly performs the process of step S1, when the signal corresponding to the detection of the water drop in the raindrop detection part 15 is not input (No in step S1).

  Step S2: The control part 17 changes the display form of the display part 13, and transfers to the process of step S3.

  Step S3: The control unit 17 determines whether or not the input of the signal corresponding to the detection of the water droplet detected by the raindrop detection unit 15 has been lost. That is, the control part 17 transfers to the process of step S4, when the input corresponding to the detection of the water drop which the raindrop detection part 15 has detected is lost (Yes in step S3). On the other hand, when the signal corresponding to the detection of the water droplet detected by the raindrop detection unit 15 is continuously input (No in step S3), the control unit 17 repeatedly executes the process of step S3.

  Step S4: The control unit 17 restores the display form of the display unit 13 and proceeds to the process of step S5.

  Step S5: The control unit 17 determines whether or not the power source of the information display device 1 that has been in the ON state is in the OFF state. That is, the control part 17 complete | finishes a process, when the power supply of the information display apparatus 1 which was in an ON state will be in an OFF state (it is Yes at step S5) (END). On the other hand, when the power source of the information display apparatus 1 that is in the ON state is not in the OFF state (No in step S5), the control unit 17 returns to the process in step S1.

(Display example 1 of the display unit 13)
Next, a display example 1 of the display unit 13 will be described with reference to FIG. The information display device 1 of FIG. 3 includes an operation unit 14-1 using a touch panel and an operation unit 14-2 using a mechanical switch.

  When the raindrop on the operation unit 14-1 that is a touch panel is detected by the raindrop detection unit 15 by the method as described above, the control unit 17 of the information display device 1 increases the character size as shown in the right diagram of FIG. 3. As a result, small characters that are difficult to see due to raindrops adhering to the display unit 13 are enlarged and made easier to see. Moreover, if the raindrop detection part 15 stops detecting the raindrop on the operation part 14-1 which is a touch panel, the control part 17 will return to the original character size like FIG. 3 left figure. In the example of the right diagram in FIG. 3, since the character size is enlarged, the characters “fire department” are out of the square indicating the fire department. As described above, when the character size is enlarged, the character may be slightly moved to a position where the enlarged character is easily visible.

(Display example 2 of the display unit 13)
Next, a display example 1 of the display unit 13 will be described with reference to FIG. The configuration of the information display device 1A in FIG. 4 is the same as the configuration of the information display device 1, but the processing for changing the display form of the display unit 13 in the control unit 17A (not shown) is different from that in the control unit 17. Therefore, description of the configuration of the information display device 1A is omitted.

  When the raindrop detection unit 15 detects a raindrop on the operation unit 14-1 that is a touch panel by the method as described above, the control unit 17A of the information display device 1A displays the raindrop on the display unit 13 as illustrated in the right side of FIG. The display size of the entire image information is enlarged. This makes it easy to see image information that has become difficult to see due to raindrops adhering to the display unit 13. When the raindrop detection unit 15 no longer detects raindrops on the operation unit 14-1, which is a touch panel, the control unit 17A restores the original display size as shown in the left diagram of FIG.

(Display example 3 of the display unit 13)
Next, a display example 3 of the display unit 13 will be described with reference to FIG. The configuration of the information display device 1B of FIG. 5 is the same as the configuration of the information display device 1, but the display form changing process of the display unit 13 in the control unit 17B (not shown) is different from that of the control unit 17. Therefore, description of the configuration of the information display device 1B is omitted.

  The control unit 17B of the information display device 1B displays a rainy weather menu as shown in the right diagram of FIG. 5 when the raindrop detection unit 15 detects a raindrop on the operation unit 14-1 that is a touch panel by the method described above. . As a result, the clear weather menu, which has become difficult to see due to raindrops adhering to the display unit 13, is changed to the rainy weather menu to make it easier to see. Further, when the raindrop detection unit 15 no longer detects raindrops on the operation unit 14-1, which is a touch panel, the control unit 17B returns to the original fine weather menu as shown in the left diagram of FIG.

  In the fine weather menu, for example, nine icons are displayed as shown in the left figure of FIG. 5, and in the rainy weather menu, for example, two icons are displayed as shown in the right figure of FIG. To do. As a result, in the rainy weather menu, as shown in the right diagram of FIG. 5, both the icon size and the character size are enlarged as compared with the sunny weather menu of the left diagram of FIG. However, it is easy to see the menu. Here, the menu is a group of icons displayed on the display unit 13 for the user to select a desired application.

(Display example 4 of the display unit 13)
Next, a display example 4 of the display unit 13 will be described with reference to FIGS. 6 and 7. The configuration of the information display device 1C in FIGS. 6 and 7 is the same as that of the information display device 1, but the display form changing process of the display unit 13 in the control unit 17C (not shown) is different from the control unit 17. Therefore, description of the configuration of the information display device 1C is omitted.

  When the raindrop detection unit 15 detects a raindrop on the operation unit 14-1 that is a touch panel superimposed on the display unit 13 by the method as described above, the control unit 17 </ b> C of the information display device 1 </ b> C is as shown in the right diagram of FIG. 6. In addition, the display size of the partial image information on the display unit 13 corresponding to the range 18 of the operation unit 14-1 in which raindrops are detected is changed. Note that it is easy for the control unit 17C to detect the range 18 to which raindrops on the operation unit 14-1 superimposed on the display unit 13 are attached because the operation unit 14-1 is a touch panel.

  FIG. 7 is a display example showing a state in which raindrops attached to the range 18 are removed with the display form of the display unit 13 of FIG. 6 as it is. The range 19 in FIG. 7 corresponds to the range 18 in FIG. That is, the image information displayed on the display unit 13 is reduced by limiting the display size to the range 19 in FIG. Thereby, when raindrops adhere to the range 18 in FIG. 6, the display size of that portion is apparently equal to the display size around the range 18.

  Further, when the raindrop detection unit 15 stops detecting raindrops on the operation unit 14-1, which is a touch panel, the control unit 17C restores the original display size as illustrated in the left diagram of FIG. Therefore, in practice, as shown in FIG. 7, the display size of the range 19 is not changed although no raindrops are attached.

  In the above-described case, if the display size is reduced for all raindrops, the visibility may be deteriorated. Therefore, the present invention may be applied to raindrops having a predetermined area or more. Moreover, since it becomes a lens shape by the surface tension of raindrops, the shape may be applied to raindrops having a substantially circular shape. For example, the present invention is applied when the area of raindrops on the display unit 13 is a circle having a diameter of 10 mm or more.

(Other embodiments)
The embodiment of the present invention can be variously modified without departing from the gist thereof. For example, the information display device 1D in FIG. 8 is a display example of the same display unit 13 as in FIG. 3, but is different from the information display device 1 in that the raindrop detection unit 15 detects raindrops using the raindrop sensor 20. According to the information display device 1D, it is not necessary to detect raindrops using the operation unit 14-1D that is a touch panel. The configuration of the information display device 1D is the same as that in FIG. 1, and the raindrop detection unit 15 includes the raindrop sensor 20.

  In addition, as described above, the raindrop sensor 20 has, for example, two electrodes arranged at a narrow interval, and outputs when a water droplet adheres between the two electrodes and the two electrodes become conductive. is there. Alternatively, a raindrop sensor 20 that is equivalent to the touch panel of the operation unit 14 may be provided. In this case, the area of the touch panel as the raindrop sensor 20 may be very small. According to this, even the raindrop sensor 20 can detect a non-conductive liquid. However, according to this, 1 C of information display apparatuses which need to specify the raindrop adhesion range of the display part 13 cannot be implement | achieved.

  Moreover, although the case where raindrops adhered to the display part 13 was demonstrated in the above-mentioned embodiment, even if it is not a raindrop, it can apply with respect to the splash of all the liquids. In particular, raindrop detection using a touch panel can be applied to non-conductive liquids.

  For example, the present invention can be applied when seawater splashes adhere to the display unit 13 near the coast. Further, the present invention can also be applied when fresh water splashes adhere to the display unit 13 in the vicinity of a mountain stream waterfall. Further, the present invention can also be applied when splashes such as non-conductive cleaning liquid adhere to the display unit 13 in a factory or the like.

  Further, a switch for manually switching between a clear screen and a rain screen may be provided. Alternatively, the display mode once automatically changed to the rainy day screen may be maintained as it is even if water droplets on the display unit 13 are no longer detected, and may be returned to the clear day screen only by manual operation.

(Program embodiment)
Further, the control units 17, 17A, 17B, 17C, and 17D of the information display devices 1, 1A, 1B, 1C, and 1D are general-purpose information processing devices (CPU, DSP (Digital Signal Processor), micro processor) that operate according to a predetermined program. It may be constituted by a processor (microcomputer) or the like. For example, a general-purpose information processing apparatus has a memory, a CPU, an input / output port, and the like. The CPU of the general-purpose information processing apparatus reads and executes a control program as a predetermined program from a memory or the like. Thereby, the functions of the control units 17, 17A, 17B, 17C, and 17D of the information display devices 1, 1A, 1B, 1C, and 1D are realized in the general-purpose information processing device.

  Note that the control program executed by the general-purpose information processing apparatus may be an information program stored in a memory or the like of the general-purpose information processing apparatus before shipment of the information display apparatuses 1, 1A, 1B, 1C, and 1D. The display devices 1, 1A, 1B, 1C, and 1D may be stored in a memory of a general-purpose information processing device after shipment. Further, a part of the control program may be stored in a memory or the like of a general-purpose information processing device after the information display devices 1, 1A, 1B, 1C, and 1D are shipped. A control program stored in a memory of a general-purpose information processing apparatus after shipment of the information display apparatuses 1, 1A, 1B, 1C, and 1D is stored in a computer-readable recording medium such as a CD-ROM. Even what installed what was downloaded may be what installed what was downloaded via transmission media, such as the internet.

  The control program includes not only a program that can be directly executed by a general-purpose information processing apparatus, but also a program that can be executed by being installed on a hard disk or the like. Also included are those that are compressed or encrypted.

(Effects according to embodiments of the present invention)
Next, effects according to the embodiment of the present invention will be described.

  The information display devices 1, 1 </ b> A, 1 </ b> B, 1 </ b> C, 1 </ b> D detect whether droplets (rain water, fresh water, seawater, washing water, etc.) have adhered to the display unit 13, and the droplets have adhered to the display unit 13. When it is detected, the display form on the display unit 13 is changed.

  This makes it possible to maintain good visibility of information displayed on the display screen even when it is used during rainfall.

  For example, the information display device 1 detects whether or not a droplet has adhered to the display unit 13. When it is detected that the droplet has adhered to the display unit 13, the character information is displayed on the display unit 13. If it is, the character size on the display unit 13 is changed.

  According to this, it is possible to make it easy to see the character information that is difficult to see due to attachment of raindrops or the like to the display unit 13.

  For example, the information display device 1 </ b> A detects whether or not a droplet has adhered to the display unit 13, and when it is detected that the droplet has adhered to the display unit 13, the information display size on the display unit 13 is displayed. To change.

  According to this, it is possible to make the display information of the entire screen difficult to see due to attachment of raindrops or the like on the display unit 13 to be easily seen as a whole.

  For example, when the information display device 1B detects whether or not a droplet has adhered to the display unit 13 and detects that the droplet has adhered to the display unit 13, the information display device 1B displays an application selection menu on the display unit 13. Change the form.

  According to this, for example, a menu for fine weather and a menu for rainy weather are prepared, and these menus can be switched depending on whether or not raindrops adhere to the display unit 13. Thereby, when it rains, the display for rainy weather considered so that it may not become difficult to see even if the raindrop adheres to the display part 13 can be performed.

  For example, the information display device 1 </ b> C detects which part of the display unit 13 has a liquid droplet attached thereto, and when it is detected that a liquid droplet has attached to any part of the display part 13, The display size is changed only in the part 13 where the droplets are attached.

  According to this, when viewed from the user, even when raindrops or the like adhere to the display unit 13, it appears as if the display form of the display unit 13 does not change, and it appears to the user both in fine weather and in rainy weather. Can provide a display with no change.

  Further, the information display device 1D includes the raindrop sensor 20, so that the process of detecting raindrops with the touch panel 14-1D can be omitted.

  In addition, the navigation device including the information display devices 1, 1 </ b> A, 1 </ b> B, 1 </ b> C, and 1 </ b> D can realize a PND that allows easy display even in rainy weather.

  In addition, by realizing the functions of the information display devices 1, 1A, 1B, 1C, and 1D using general-purpose information processing devices and programs, it becomes possible to flexibly deal with mass production and specification changes (or design changes).
