Title: Electronic equipment and navigation apparatus

Description:
BACKGROUND OF THE INVENTION  
       [0001] 1. Field of the Invention  
       [0002] The present invention relates to an electronic equipment including a display part. The present invention also relates to a navigation apparatus for setting an arbitrary position on a displayed map image as a point relating to a navigation.  
       [0003] 2. Description of the Related Art  
       [0004] In a general vehicle-mounted acoustic apparatus of a conventional electronic equipment that includes a display part, symbols showing objects to be controlled such as an icon showing a radio, an icon showing a CD player and an icon showing a title of music of a CD are displayed on a screen of the display part. In the vehicle-mounted acoustic apparatus, symbols showing details of the control such as an icon showing repeat reproduction and an icon showing an adjustment mode are also displayed on the screen of the display part. In order to select an arbitrary icon on the screen, a cursor switch for moving a cursor displayed on the screen and an execution switch for selecting a control object by an icon of a cursor position and for selecting details of the control by an icon of a cursor position are also provided in the vehicle-mounted acoustic apparatus. In an operating procedure of such a vehicle-mounted acoustic apparatus, for example, when a user intends to repeatedly reproduce music of a CD, an icon of a CD to be reproduced is selected by a depression operation of the cursor switch and the CD corresponding to the icon is selected by a depression operation of the execution switch. Next, an icon of repeat reproduction is selected by a depression operation of the cursor switch and the repeat reproduction is selected by a depression operation of the execution switch.  
       [0005] Incidentally, in the conventional electronic equipment including the display part without being limited to such vehicle-mounted acoustic apparatus described above, it is configured so as to perform desired control by a switch operation with respect to a symbol displayed on the screen of the display part. There exist an enormous number of references describing such a configuration and is quite difficult to disclose a specific reference as the most proper prior art reference. Therefore, the operating procedure of the vehicle-mounted acoustic apparatus conventionally well known among those skilled in the art as described above is taken as one example of a conventional art relating to the present invention.  
       [0006] Also, an operating procedure of a conventional navigation apparatus capable of setting an arbitrary position on a displayed map image as a point relating to navigation is approximately similar to that of the case of the conventional vehicle-mounted acoustic apparatus. For example, when an arbitrary point is registered as a point relating to navigation, a cursor is first displayed on a displayed map image by a touch operation of a registration switch for setting point registration. Next, the cursor is moved in an arbitrary position of the map by a depression operation of the cursor switch and an actual point corresponding to the cursor position at that time is set as a registration point by a depression operation of the execution switch.  
       [0007] Incidentally, a configuration of such a conventional navigation apparatus is quite generally configured and there exist an enormous number of references describing such a configuration and it is quite difficult to disclose a specific reference as the most proper prior art reference. Therefore, the operating procedure of the general navigation apparatus well known already among those skilled in the art as described above is taken as one example of the conventional art relating to the present invention.  
       [0008] In the conventional electronic equipment described above, there was a problem that in order to execute desired details of the control with respect to a desired control object, it is necessary to perform troublesome switch operations many times and an excessive burden on a user is forced. As a result, for example, in the vehicle-mounted acoustic apparatus used as one example of the conventional electronic equipment, there was a problem that troublesome switch operations must be performed many times with respect to a user particularly in driving when a sound source device such as a radio or a CD player device is selected or a desired CD is selected to perform repeat reproduction.  
       [0009] Also, in the conventional navigation apparatus described above, in a manner similar to the case of the conventional electronic equipment, there was a problem that, for example, in order to set a desired position on a displayed map image as a registration point, it is necessary to perform troublesome switch operations many times and an excessive burden on a user is forced.  
       SUMMARY OF THE INVENTION  
       [0010] It is therefore an object of the invention is to provide an electronic equipment capable of easily executing desired details of the control with respect to a desired control object without performing a troublesome switch operation.  
       [0011] Another object of the invention is to provide a navigation apparatus capable of easily setting a desired position on a displayed map image as a point relating to navigation without performing a troublesome switch operation.  
       [0012] In order to achieve the object, according to one aspect of the invention, there is provided an electronic equipment including: a display unit configured to display a first symbol indicating a control object and a second symbol indicating details of a control in a predetermined display position, respectively; a selection unit configured to select at least one of the first and the second symbols displayed on the display unit in response to an instruction operation; a movement unit configured to move the display position of the selected symbol in response to a movement operation; and a control unit configured to execute the details of the control corresponding to the second symbol with respect to the control object corresponding to the first symbol in response to an execution operation.  
       [0013] In order to achieve the object, according to another aspect of the invention, there is provided a navigation apparatus including: a display unit configured to display a map image and a symbol relating to navigation in a predetermined display position, respectively; a selection unit configured to select the symbol displayed on the display unit in response to an instruction operation;  
       [0014] a movement unit configured to move the display position of the selected symbol in response to a movement operation; and a control unit configured to configure a point corresponding to a position on the map image as a point relating to navigation, the position in which the display position of the selected symbol is moved to in response to a configuration operation.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
     [0027] Hereinbelow, first to fourth embodiments of an electronic equipment according to the invention will be described with reference to the drawings by taking a vehicle-mounted acoustic apparatus as an example of the electronic equipment. FIG. 1 is an outline view showing a structure of the vehicle-mounted acoustic apparatus in the first to fourth embodiments.  
     [0028] The vehicle-mounted acoustic apparatus shown in FIG. 1 is provided with an operating panel  2  on the front of a cabinet  1 . A volume knob  3  for volume control is provided in a position near to the end of the operating panel  2 . Also, an opening  2   a  is formed in the approximately center of the operating panel  2  and a display touch sensor  4  is exposed to an opening  2   a  of the operating panel  2 . Specifically, the vehicle-mounted acoustic apparatus is configured so that a touch sensor having a switch function of shifting to an on state in response to a touch (also called “depression” which applies to the other embodiments) is placed on a display surface of a display having a display function.  
     [0029] A display (corresponding to display unit) is constructed of an LCD (liquid crystal display device). Also, a touch sensor is constructed of a transparent conductive film using ITO (Indium Tin Oxide: a compound of indium, tin and oxygen) as material, and is formed on a display surface of the LCD by an electron beam evaporation method or a sputtering method.  
     [0030]FIG. 2 is a block diagram showing a system configuration of the vehicle-mounted acoustic apparatus of FIG. 1. A sound source device  10  for providing a sound source such as a sound or a musical sound comprises a radio device  11 , a CD player device  12 , a CD changer device  13 , an MD changer device  14  and other devices  15 . A main CPU  20  (corresponding to selection unit, movement unit and control unit) is connected to each of these devices through a system bus, and performs control with respect to each the device in response to a command of a user inputted from the display touch sensor  4 . The main CPU  20  is connected to the display touch sensor  4  through an interface circuit  30 , and captures a command from a touch sensor  4   a  in response to an operation of the user, and outputs image data to be displayed to a display  4   b.    
     [0031]FIGS. 3 a  through  3   e  are diagrams showing an operating procedure of the case of controlling the CD player device  12  in a first embodiment. FIG. 4 is a flowchart of control processing by the main CPU  20 . An operation of the first embodiment will be described below with reference to FIGS. 3 a  through  3   e  and FIG. 4. Incidentally, in the flowchart of FIG. 4, only the main points related to the invention will be described and description of other general processing will be omitted.  
     [0032] In FIG. 3 a , a symbol  41  (corresponding to a first symbol) and a symbol  42  (corresponding to a second symbol) are displayed on a screen of the display touch sensor  4 . The symbol  41  is an icon showing a particular CD which is a control object, and the symbol  42  is an icon showing repeat reproduction which is details of the control. Incidentally, the details of the control include random reproduction or scan reproduction other than the repeat reproduction, and are displayed by unique icons, respectively.  
     [0033] As shown in FIG. 3 b , when a user touches an icon of the symbol  41  with a finger  5  for a predetermined time (for example, two or three seconds) or longer as a predetermined instruction operation, the main CPU  20  detects the instruction operation through the touch sensor  4   a  and the interface circuit  30  (step S 1  to step S 3 ), and selects the icon of the symbol  41  and the number of the particular CD corresponding to the icon (step S 4 ). In the case, the main CPU  20  blinks the icon of the symbol  41  and notifies the user that the corresponding particular CD is selected (step S 5 ).  
     [0034] Then, as shown in FIG. 3 c , when the user drags (moves) in a direction of an arrow of the drawing with the icon of the symbol  41  touched with the finger  5  as a predetermined movement operation, the main CPU  20  moves a display position of the icon of the symbol  41  in response to the movement operation (step S 6  to step S 8 ). In the case, an icon whose contrast is weakened (the degree of display is decreased) may be displayed in the original display position of the icon of the symbol  41 .  
     [0035] As shown in FIG. 3 d , when the user moves the finger  5  in a touch state to an icon of the symbol  42  and stops the drag, a display position of the icon of the symbol  41  overlaps with a display position of the icon of the symbol  42 . When the main CPU  20  detects a stop of the drag (step S 9 ) and further detects that the stop position is located on the symbol  42  (step S 10 ), as shown in FIG. 3 e , the main CPU  20  blinks the icon of the symbol  42  and notifies the user that the details of the control of the icon of the symbol  42  are executed (step S 11 ). Then, the main CPU  20  loads the selected particular CD (step S 12 ) and executes repeat reproduction of the CD (step S 13 ).  
     [0036] In the embodiment, the CPU  20  executes the details of the control (repeat reproduction) when the CPU  20  detects that the display position of the first symbol (icon of the symbol  41 ) overlaps the display position of the second symbol (icon of the symbol  42 ) at a time the movement operation has stopped (i.e. when the CPU  20  detects a stop of the drag operation). However, the CPU  20  may configured to execute the details of the control when the CPU  20  detects a drop operation in which the finger has moved away from the touch sensor  4   a  in a condition where the display position of the first symbol overlaps the display position of the second symbol.  
     [0037]FIGS. 5 a  through  5   e  are diagrams showing an operating procedure of the case of controlling the CD changer device  13  in a second embodiment. Incidentally, control processing performed by the main CPU  20  in the second embodiment is nearly equal to control processing of the first embodiment shown in FIG. 4, so that a flowchart is omitted.  
     [0038] As shown in FIG. 5 a , a symbol  43  (corresponding to a first symbol) and a symbol  42  (corresponding to a second symbol) are displayed on a screen of the display touch sensor  4 . The symbol  43  is plural icons showing plural CDs (six in the case) which are control objects. Also, the symbol  42  is an icon showing repeat reproduction which is details of the control in a manner similar to the first embodiment.  
     [0039] As shown in FIG. 5 b , when a user touches one icon (icon of the second CD in the case) of the symbol  43  with a finger  5  for a predetermined time (for example, two or three seconds) or longer as a predetermined instruction operation, the main CPU  20  detects the instruction operation through the touch sensor  4   a  and the interface circuit  30 , and selects the icon of the symbol  43  and the number of the particular CD corresponding to the icon. In the case, the main CPU  20  blinks the corresponding icon of the symbol  43  and notifies the user that the corresponding particular CD is selected.  
     [0040] Then, as shown in FIG. 5 c , when the user drags (moves) in a direction of an arrow of the drawing with the selected icon touched with the finger  5  as a predetermined movement operation, the main CPU  20  moves a display position of the icon in response to the movement operation. In the case, an icon whose contrast is weakened may be displayed in the original display position of the icon.  
     [0041] As shown in FIG. 5 d , when the user moves the finger  5  in a touch state to an icon of the symbol  42  and stops the drag, a display position of the selected icon of the symbol  43  overlaps with a display position of the icon of the symbol  42 . When the main CPU  20  detects a stop of the drag and further detects that the stop position is located on the symbol  42 , as shown in FIG. 5 e , the main CPU  20  blinks the selected icon of the symbol  43  and selects a CD of the icon and notifies the user that the details of the control of the symbol  42  are executed. Then, the main CPU  20  loads the selected particular CD and executes repeat reproduction.  
     [0042]FIGS. 6 a  through  6   e  are diagrams showing an operating procedure of the case of controlling the radio  11 , the CD player device  12  and the CD changer device  13  in a third embodiment. Incidentally, control processing performed by the main CPU  20  in the third embodiment is nearly equal to control processing of the first embodiment shown in FIG. 4, so that a flowchart is omitted.  
     [0043] As shown in FIG. 6 a , a symbol  44  (corresponding to a first symbol) and a symbol  45  (corresponding to a second symbol) are displayed on a screen of the display touch sensor  4 . The symbol  44  is plural icons  44   a ,  44   b ,  44   c  showing plural devices (three in the case) which are control objects. Also, the symbol  45  is an icon showing channels which are details of the control.  
     [0044] The details of the control of channels have meaning different depending on the control objects. When the control object is the radio  11 , the number of the channel is used for selection of a broadcast station. When the control object is the CD player device  12 , the number of the channel is used for selection of music. When the control object is the CD changer device  13  (also as in the MD changer device  14 ), the number of the channel is used for selection of a disk (CD or MD).  
     [0045] As shown in FIG. 6 b , when a user touches one icon (icon  44   a  of the radio in the case) of the symbol  44  with a finger  5  for a predetermined time (for example, two or three seconds) or longer as a predetermined instruction operation, the main CPU  20  detects the instruction operation through the touch sensor  4   a  and the interface circuit  30 , and selects the icon  44 a and the radio  11  corresponding to the icon  44   a . In the case, the main CPU  20  blinks the corresponding icon  44   a  of the symbol  44  and notifies the user that the device corresponding to the touch of the finger is selected.  
     [0046] Then, as shown in FIG. 6 c , when the user drags (moves) in a direction of an arrow of the drawing with the selected icon touched with the finger  5  as a predetermined movement operation, the main CPU  20  moves a display position of the icon in response to the movement operation. In the case, an icon whose contrast is weakened may be displayed in the original display position of the icon.  
     [0047] As shown in FIG. 6 d , when the user moves the finger  5  in a touch state to an icon of the symbol  45  and stops the drag, a display position of the selected icon  44   a  overlaps with a display position of the icon of the symbol  45 . When the main CPU  20  detects a stop of the drag and further detects that the stop position is located on the channel number of the symbol  45 , as shown in FIG. 6 e , the main CPU  20  blinks the selected icon  44   a  of the symbol  44  and also reverses display of the selected channel number of the symbol  45  and notifies the user that broadcast of channel 3 is selected. That is, the user is notified that the selected details of the control are executed with respect to the selected control object. Then, the radio  11  is started and processing for receiving the broadcast of channel 3 is performed.  
     [0048] Incidentally, in the third embodiment, as a receiver of broadcast, the radio  11  is taken as an example, and a similar operating procedure is used also in the case of a receiver for receiving television broadcast.  
     [0049]FIGS. 7 a  through  7   e  are diagrams showing an operating procedure of the case of changing a title of music of a disk such as CD or MD in a fourth embodiment. Incidentally, control processing in the fourth embodiment is nearly equal to control processing of the first embodiment shown in FIG. 4, so that a flowchart is omitted.  
     [0050] As shown in FIG. 7 a , a symbol  46  (corresponding to a first symbol) and a symbol  47  (corresponding to a second symbol) are displayed on a screen of the display touch sensor  4 . The symbol  46  is an icon showing a title which is a control object, and the symbol  47  is an icon showing an adjustment mode which is details of the control.  
     [0051] As shown in FIG. 7 b , when a user touches the symbol  46  with a finger  5  for a predetermined time (for example, two or three seconds) or longer as a predetermined instruction operation, the main CPU  20  detects the instruction operation through the touch sensor  4   a  and the interface circuit  30 , and selects the symbol  46  and an address of memory in which the title is stored. In the case, the main CPU  20  blinks the title which is the icon of the symbol  46  and notifies the user that the title is selected as an adjustment object.  
     [0052] Then, as shown in FIG. 7 c , when the user drags (moves) in a direction of an arrow of the drawing with the selected icon touched with the finger  5  as a predetermined movement operation, the main CPU  20  moves a display position of the icon in response to the movement operation. In the case, an icon whose contrast is weakened may be displayed in the original display position of the icon.  
     [0053] As shown in FIG. 7 d , when the user moves the finger  5  in a touch state to an icon of the symbol  47  and stops the drag, a display position of the symbol  46  overlaps with a display position of the icon of the symbol  47 . When the main CPU  20  detects a stop of the drag and further detects that the stop position is located on the symbol  47 , as shown in FIG. 7 e , the main CPU  20  blinks and displays a symbol  48  showing scroll processing for changing the title in the original display position of the symbol  46 . That is, notification that the selected details of the control are executed with respect to the selected control object is provided.  
     [0054] According to the first to fourth embodiments as described above, the touch sensor  4   a  of a display position corresponding to at least one of an arbitrary first symbol or an arbitrary second symbol displayed is selected in response to a touch operation of the finger and a display position of the selected symbol is moved in response to a drag operation on the touch sensor  4   a  with the display position touched and the details of the control corresponding to the second symbol are executed with respect to the control object corresponding to the first symbol in the case of detecting that a display position of the first symbol overlaps with a display position of the second symbol by a stop of the drag operation, so that desired details of the control can be executed easily with respect to a desired control object by only the touch operation of the touch sensor  4   a  without performing a troublesome switch operation.  
     [0055] Also, according to the first to fourth embodiments as described above, when the touch sensor is touched for a predetermined time or longer in a display position of an arbitrary symbol, the symbol is selected, so that a malfunction due to an instantaneous touch can be prevented.  
     [0056] Incidentally, in the first to fourth embodiments as described above, the electronic equipment of the invention has been described by taking the vehicle-mounted acoustic apparatus as an example, but the electronic equipment of the invention is not limited to the vehicle-mounted acoustic apparatus of the embodiments. That is, as long as the electronic equipment is configured so as to have display unit for displaying at least one first symbol showing a control object and at least one second symbol showing details of the control, selection unit for selecting at least one of an arbitrary first symbol or an arbitrary second symbol displayed on the display unit in response to a predetermined instruction operation, movement unit for moving a display position of the symbol selected by the selection unit in response to a predetermined movement operation, and control unit for executing the details of the control corresponding to the second symbol with respect to the control object corresponding to the first symbol in the case of detecting that a display position of the first symbol overlaps with a display position of the second symbol by a stop of the movement operation, the invention can be applied to any electronic equipment other than the vehicle-mounted acoustic apparatus.  
     [0057] Next, a fifth embodiment of electronic equipment of the invention will be described based on the drawings by taking a display system apparatus having a large display screen used in a meeting or a lecture as an example. FIG. 8 is an outline view showing the display system apparatus in the fifth embodiment. A display system apparatus  6  comprises a display sensor  7  which is a large display screen. This display sensor  7  is constructed of a display having a function of displaying an image and a light sensor having a function of detecting irradiation of a light beam. As the light sensor, for example, manufacture is performed by forming a semiconductor such as a photodiode or a phototransistor having a light detection function in a transparent conductive film made of ITO.  
     [0058] Now, a symbol  49  (corresponding to a first symbol) acting as a control object and a symbol  50  (corresponding to a second symbol) acting as details of the control are displayed on the display sensor  7 . In the case, an image of a document for meeting is the symbol  49 , and a symbol  50   a  of print for processing the document, a symbol  50   b  of fax, a symbol  50   c  of change and a symbol  50   d  of other processing are displayed.  
     [0059] A laser instruction device  8  is a device for emitting a light beam  9  of a red laser. A user such as a presenter of a meeting can irradiate the display sensor  7  with the light beam  9  emitted by an operation of the laser instruction device  8  and select an arbitrary position of a display screen. Further, by moving the light beam  9  on the screen in a state of irradiating an arbitrary symbol, a drag operation can be performed in a manner similar to the case on the touch sensor in the first to fourth embodiments.  
     [0060]FIG. 9 is a block diagram showing a system configuration of the display system apparatus  6  of FIG. 8. A main CPU  61  is connected to the display sensor  7  through an interface circuit  62  and controls a light sensor  7   a  and a display  7   b . Also, the main CPU  61  is connected to an image server  63 , a printer  64  and other devices  65  such as fax, and sends and receives data and commands to and from these. A document and other image data corresponding to the symbol  49  displayed on the display  7   b  as a control object are stored in the image server  63 .  
     [0061] In the fifth embodiment, an operation of control processing of the main CPU  61  will be described, but control processing in the case is nearly equal to control processing of the first embodiment shown in FIG. 4 except that processing for detecting irradiation of the light beam  9  is performed rather than processing for detecting a touch of a finger, so that a flowchart for the fifth embodiment is omitted.  
     [0062] In FIG. 8, when a user irradiates one image  49   a  of the symbol  49  with the light beam  9  from the laser instruction device  8  for a predetermined time (for example, two or three seconds) or longer as a predetermined instruction operation, the main CPU  61  detects the instruction operation through the light sensor  7   a  and the interface circuit  62 , and selects the image  49   a  of the symbol  49 . In the case, the main CPU  61  blinks the image  49   a  of the symbol  49  and notifies the user that the image is selected.  
     [0063] When the user drags (moves) in a direction of an arrow of the drawing with the selected image  49   a  of the symbol  49  irradiated with the light beam  9  as a predetermined movement operation, the main CPU  61  moves a display position of the image  49   a  in response to the movement operation. In the case, an icon whose contrast is weakened may be displayed in the original display position of the image  49   a.    
     [0064] When the user moves the light beam  9  to an image  50   a  of a print mark of the symbol  50  in a state of irradiation and stops the drag, a display position of the image  49   a  of the symbol  49  overlaps with a display position of the image  50   a  of the print mark of the symbol  50 . When the main CPU  61  detects a stop of the drag and further detects that the stop position is located on the image  50   a  of the print mark of the symbol  50 , the main CPU  61  reads image data of a document corresponding to the image  49   a  of the symbol  49  out of the image server  63  and outputs the image data to the printer  64  to provide printout. This also applies to images other than the image  50   a  of the print mark. For example, when the image  49   a  of the symbol  49  is dragged on an image  50   b  of a fax mark, image data of a document corresponding to the image  49   a  of the symbol  49  is read out of the image server  63  and is sent by fax. That is, the selected details of the control are executed with respect to the selected control object.  
     [0065] According to the fifth embodiment as described above, since the irradiation position is detected in response to a particular light beam with which the display screen  7  on which the symbol is displayed is irradiated, an instruction operation by irradiation of the light beam  9  and a movement operation by drag of the light beam  9  can be performed using the laser instruction device  8  for emitting the particular light beam  9  of a red laser, so that desired details of the control can be executed easily with respect to a desired control object by an untouched remote control operation from a position distant from the display screen without performing a troublesome switch operation.  
     [0066] According to the fifth embodiment as described above, when the light sensor  7   a  is irradiated with the light beam  9  for a predetermined time or longer in a display position of an arbitrary symbol, the symbol irradiated with the light beam is selected, so that a malfunction due to instantaneous irradiation of the light beam can be prevented.  
     [0067] A navigation apparatus in a sixth embodiment of the invention will be described based on the drawings. An outward appearance of the navigation apparatus is nearly equal to an outward appearance of the vehicle-mounted acoustic apparatus of the first embodiment shown in FIG. 1. That is, an operating panel is provided on the front of a cabinet, and an opening is formed in the approximately center of the operating panel and a display touch sensor is exposed to the opening. Specifically, the navigation apparatus is configured so that a touch sensor having a switch function of shifting to an on state in response to a touch is placed on a display surface of a display having a display function.  
     [0068]FIG. 10 is a block diagram showing a system configuration of the navigation apparatus in the sixth embodiment. As shown in the drawing, a CD-ROM player  71  for reproducing CD-ROM in which data of a map image is stored, a vehicle sensor  72  for detecting a position of a vehicle, a direction of the vehicle, a vehicle speed, etc., and other devices  73  such as a receiver for receiving traffic information are connected to a system bus of a main CPU  74  (corresponding to selection unit, movement unit and setting means). Also, a display touch sensor  76  (corresponding to display unit) is connected to the main CPU  74  through an interface circuit  75 , and a touch sensor  76   a  and a display  76   b  are controlled.  
     [0069]FIGS. 11 a  through  11   e  are diagrams showing an operating procedure of the case of performing point registration of navigation. Incidentally, an operation of control processing of the main CPU  74  is nearly equal to control processing of the first embodiment shown in FIG. 4, so that a flowchart for the sixth embodiment is omitted.  
     [0070] As shown in FIG. 11 a , a symbol  77  (corresponding to a symbol) and a map image  78  are displayed on a screen of the display touch sensor  76 . The symbol  77  is an icon showing point registration which is one of navigation processing. In addition to the icon of the symbol  77 , a symbol  79  about various navigation processing such as route finding or freeway toll calculation is displayed.  
     [0071] As shown in FIG. 11 b , when a user touches an icon of the symbol  77  with a finger  5  for a predetermined time (for example, two or three seconds) or longer as a predetermined instruction operation, the main CPU  74  detects the instruction operation through the touch sensor  76   a  and the interface circuit  75 , and selects the icon of the symbol  77  and a command of point registration corresponding to the icon. In the case, the main CPU  74  blinks the icon of the symbol  77  and notifies the user that the point registration is selected.  
     [0072] Then, as shown in FIG. 11 c , when the user drags (moves) in a direction of an arrow of the drawing with the icon of the symbol  77  touched with the finger  5  as a predetermined movement operation, the main CPU  74  moves a display position of the icon in response to the movement operation. In the case, an icon whose contrast is weakened may be displayed in the original display position of the icon.  
     [0073] As shown in FIG. 11 d , when the user moves the finger  5  in a touch state to a particular point on the map image  78  and stops the drag, a display position of the icon of the symbol  77  overlaps with a display position of the point. When the main CPU  74  detects a stop of the drag, as shown in FIG. 11 e , the main CPU  74  blinks the icon of point registration of the symbol  77  in a selected position of the map image  78  and notifies the user that a point corresponding to the position is set as a registration point. Simultaneously, data of an actual point corresponding to the position of the map image is registered in memory.  
     [0074] Incidentally, in the sixth embodiment described above, the invention has been described as a symbol relating to navigation by taking a symbol of point registration as an example but, for example, when a symbol of route finding is dragged in a position of the purpose of a map image, the route closest to the point can be displayed on the map image without performing a troublesome switch operation. Or, when a symbol of freeway toll calculation is dragged in a position of a tollgate of a map image, a freeway toll to be paid is displayed on the display  76   b.    
     [0075] According to the navigation apparatus of the sixth embodiment, an arbitrary symbol displayed is selected in response to a touch of a finger and a display position of the symbol selected is moved in response to a drag operation and a point corresponding to a position on a map image in which the display position of the symbol selected is present is set as a point relating to navigation by a stop of the drag operation, so that a desired position on a displayed map image can be set easily as the point relating to navigation without performing a troublesome switch operation.  
     [0076] According to the electronic equipment of the invention configured as described above, at least one of an arbitrary first symbol or an arbitrary second symbol displayed is selected in response to a predetermined instruction operation and a display position of the selected symbol is moved in response to a predetermined movement operation and the details of the control corresponding to the second symbol are executed with respect to the control object corresponding to the first symbol in the case of detecting that a display position of the first symbol overlaps with a display position of the second symbol by a stop of the movement operation, so that desired details of the control can be executed easily with respect to a desired control object without performing a troublesome switch operation.  
     [0077] Also, according to a navigation apparatus of the invention constructed as described above, an arbitrary symbol displayed is selected in response to a predetermined instruction operation and a display position of the symbol selected is moved in response to a predetermined movement operation and a point corresponding to a position on a map image in which the display position of the symbol selected is present is set as a point relating to navigation by a stop of the movement operation, so that a desired position on a displayed map image can be set easily as the point relating to navigation without performing a troublesome switch operation.  
     [0078] Although the present invention has been shown and described with reference to specific preferred embodiments, various changes and modifications will be apparent to those skilled in the art from the teachings herein. Such changes and modifications as are obvious are deemed to come within the spirit, scope and contemplation of the invention as defined in the appended claims.
