  Although the portable terminal of Patent Document 1 switches processing according to the operation pressure (pressing force) applied to the touch panel, it is not a configuration capable of three-dimensional display, so even if the operation pressure is changed, two-dimensional display to three-dimensional display is possible. Switching to display is not possible.

  In addition, even the devices disclosed in Patent Documents 2 to 5 cannot use input from a pointing device such as a touch pad or a touch panel to switch from 2D display to 3D display.

  The present invention has been made in view of the above-described problems, and an electronic device that allows a user to easily switch from a two-dimensional display to a three-dimensional display by using a pressing force, and the electronic device A display control method and a program.

  According to one aspect of the present invention, the electronic device is an electronic device capable of displaying a three-dimensional image.

When the pressing force is detected, the processor causes the display to three-dimensionally display an image of at least a part of the display area on the display in a manner of popping out from the display. The processor maintains the three-dimensional display of the image even if the pressing force is not detected after the image is three-dimensionally displayed. The processor determines whether the distance between the second sensor and the object is within a predetermined distance. When the processor determines that the distance is within a predetermined distance while maintaining the three-dimensional display of the image, the processor switches the three-dimensional display of the image to the two-dimensional display.

Preferably, the second sensor is provided on the first surface.

  Preferably, the memory stores a threshold value related to the pressing force. When the pressing force equal to or greater than the threshold is detected, the processor displays the image at the pointer position and the image around the pointer position in a three-dimensional manner.

  Preferably, the memory further stores first data representing a display area of an object included in the image. The processor determines whether the position designated by the device is included in the display area of the object based on the first data. When determining that the processor is included in the display area of the object, the processor displays the object in a three-dimensional manner.

  Preferably, the memory further stores second data in which the pressing force and the popping amount are associated with each other so that the popping amount of the image increases as the pressing force increases. Based on the second data, the processor displays the object three-dimensionally with a pop-out amount corresponding to the pressing force.

  Preferably, the processor reduces the pop-out amount of the three-dimensionally displayed object as the distance between the second sensor and the object becomes shorter.

  Preferably, the memory further stores data representing the pop-out amount of the image so that the pop-out amount of the image at the position designated by the device is maximized and the pop-out amount decreases as the distance from the position increases. The processor maximizes the pop-out amount of the image at the designated position based on the data, and decreases the pop-out amount as the distance from the position increases.

  Preferably, in the data, the pressing force and the pop-out amount are further correlated so that the higher the pressing force, the larger the pop-out amount of the image. Based on the data and the pressing force, the processor maximizes the pop-out amount of the image at the position designated by the device, and decreases the pop-out amount as the distance from the position increases.

  Preferably, in the data, the pressing force and the width of the display area to be displayed three-dimensionally are further associated with each other so that the display area to be three-dimensionally displayed becomes wider as the pressing force is higher. The processor determines a display area to be three-dimensionally displayed based on the data and the pressing force.

Referring to FIG. 3, the data table 41 defines the relationship between the pressing force P and the popping amount so that the popping amount becomes zero when the pressing force P is not less than 0 and less than the threshold ThP1. That is, in the data table 41, when the user does not touch the touch pad 110 or only touches it lightly, the relationship between the pressing force P and the pop-out amount is specified so that two-dimensional display is performed. Has been.

  Further, the data table 41 defines the relationship between the pressing force P and the popping amount so that the popping amount becomes small when the pressing force P is not less than the threshold ThP1 and less than the threshold ThP2. The data table 41 defines the relationship between the pressing force P and the popping amount so that the popping amount becomes medium when the pressing force P is equal to or greater than the threshold ThP2 and less than the threshold ThP3. The data table 41 defines the relationship between the pressing force P and the popping amount so that the popping amount becomes large when the pressing force P is equal to or greater than the threshold ThP3.

  That is, in the data table 41, when the pressing force P exceeds the threshold ThP1, three-dimensional display is performed, and the pressing force P and the pop-out amount are set so that the pop-out amount of the image or the object increases as the pressing force P increases. It is associated. The method of using the data table 41 will be described later (FIGS. 5 and 7).

  FIG. 5 is a diagram for explaining an example of display control in the electronic apparatus 1. FIG. 5A is a diagram showing a state in which the pressing force P less than the threshold ThP1 is applied to the touch pad 110. FIG. FIG. 5B is a diagram showing a state in which a pressing force P not less than the threshold ThP1 and less than the threshold ThP2 is applied to the touch pad 110 after FIG. 5A. FIG. 5C is a diagram illustrating a state in which a pressing force P not less than the threshold ThP2 and less than the threshold ThP3 is applied to the touch pad 110 after FIG. 5A. FIG. 5D is a diagram illustrating a state where a pressing force P equal to or higher than the threshold ThP3 is applied to the touch pad after FIG. 5A.

  Referring to FIG. 5A, the user moves the pointer 309 by bringing a finger into contact with the touch pad 110 with a pressing force less than the threshold ThP1. For example, the user moves the pointer 309 onto the object 301. The objects 301, 302, and 303 are an object representing an apple, an object representing a banana, and an object representing a melon, respectively.

  The flash memory 104 or the RAM 103 stores data (coordinate data) for designating display areas of the objects 301, 302, and 303. The CPU 101 displays the objects 301, 302, and 303 on the display 105 based on the data. The CPU 101 determines whether or not the position of the pointer 309 is included in the display areas of the objects 301, 302, and 303. That is, the CPU 101 determines whether or not the position of the pointer 309 is on the objects 301, 302, and 303.

  Referring to FIG. 5B, when the CPU 101 determines that the pressing force P not less than the threshold ThP1 and less than the threshold ThP2 is applied to the touch pad 110 when the pointer 309 is on the object 301, based on the data table 41. Then, the pop-up amount is set to “small”, and the object 301 is displayed three-dimensionally on the display 105. At that time, in order to improve the visibility of the object 301, the CPU 101 hides the pointer 309. The same applies to FIGS. 5C and 5D.

  The CPU 101 continues to three-dimensionally display the object 301 on the display 105 by setting the pop-out amount to “small” unless the pressing force P equal to or greater than the threshold ThP2 is applied to the touch pad 110. Even if the pressing force P is no longer applied to the touch pad 110 when the user removes his / her finger from the touch pad 110, the CPU 101 continues to display the object 301 on the display 105 in a three-dimensional manner with the amount of popping out being “small”.

  Referring to FIG. 5C, when CPU 101 determines that pressing force P not less than threshold value ThP2 and less than threshold value ThP3 is applied to touch pad 110 when pointer 309 is on object 301, based on data table 41. The object 301 is displayed three-dimensionally on the display 105 with the pop-out amount set to “medium”.

  The CPU 101 continues to display the object 301 three-dimensionally on the display 105 with the pop-out amount being “medium” unless the pressing force P equal to or greater than the threshold ThP3 is applied to the touch pad 110. Even if the pressing force P is no longer applied to the touch pad 110 when the user removes his / her finger from the touch pad 110, the CPU 101 continues to display the object 301 on the display 105 in a three-dimensional manner with the amount of popping out being “medium”.

  Referring to FIG. 5D, when the CPU 101 determines that the pressing force P equal to or greater than the threshold ThP3 is applied to the touch pad 110 when the pointer 309 is on the object 301, the pop-out amount is determined based on the data table 41. Is set to “large”, and the object 301 is three-dimensionally displayed on the display 105.

  Even if the pressing force P is no longer applied to the touch pad 110 when the user removes his / her finger from the touch pad 110, the CPU 101 keeps the object 301 three-dimensionally displayed on the display 105 with the pop-out amount being “large”.

  As described above, the CPU 101 places the object 301 on the display 105 with the pop-out amount associated with the range (four categories in FIG. 4) including the highest pressing force among the pressing forces detected by the pressure sensor 121. Continue to display 3D.

  The processing of the CPU 101 will be described in detail with attention to the object 301 as follows. The CPU 101 specifies the position of the pointer 309 to which the pressing force equal to or greater than the threshold ThP1 is applied. The CPU 101 determines whether or not the specified position of the pointer 309 is included in the display area of the object 301. When the CPU 101 determines that the object is included in the display area of the object 301, the CPU 101 displays the object 301 three-dimensionally. Based on the data table 41, the CPU 101 displays the object 301 in a three-dimensional manner with a pop-out amount corresponding to the pressing force.

  Note that even when the user moves the pointer 309 over the objects 302 and 303 and applies a pressing force P equal to or greater than the threshold ThP1 to the touch pad 110, the CPU 101 causes the objects 302 and 303 to jump out according to the pressing force. Is displayed three-dimensionally.

  Note that the control of the pop-out amount can be realized by changing the positional shift in the display 105 between the right-eye image and the left-eye image. By increasing the deviation, the pop-out amount can be increased, and by reducing the shift, the pop-out amount can be reduced. That is, when the parallax is increased, the pop-out amount increases, and when the parallax is decreased, the pop-out amount can be reduced.

  FIG. 6 is a diagram showing screen transitions when the user gradually moves the finger 901 closer to the distance measuring sensor 112 from a state where the pop-up amount is “large” and the object 301 is three-dimensionally displayed on the display 105. . That is, FIG. 6 is a diagram showing screen transition from FIG.

  FIG. 6A shows a state in which the user brings the finger 901 closer to the distance measuring sensor 112 in a state where the pop-up amount is “large” and the object 301 is three-dimensionally displayed on the display 105. More specifically, FIG. 6A shows a state where the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD3.

  6B, the user further brings the finger 901 closer to the distance measuring sensor 112 from the state of FIG. 6A, and the distance between the finger 901 and the distance measuring sensor 112 is not less than the threshold ThD2 and less than the threshold ThD3. The state is shown. 6C, the user further brings the finger 901 closer to the distance measuring sensor 112 from the state of FIG. 6B, and the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD1 and less than the threshold ThD2. The state is shown. FIG. 6D shows a state in which the user further brings the finger 901 closer to the distance measuring sensor 112 from the state of FIG. 6C, and the distance between the finger 901 and the distance measuring sensor 112 is less than the threshold ThD1. Show.

  Referring to FIG. 6A, when the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD3, the CPU 101 displays the object 301 on the display 105 in a three-dimensional manner with the pop-out amount being “large”. Keep it as it is.

  Referring to FIG. 6B, when the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD2 and less than the threshold ThD3, the CPU 101 sets the pop-out amount to “medium” and places the object 301 on the display 105. 3D display. As long as the distance between the finger 901 and the distance measuring sensor 112 is not less than the threshold ThD2, the CPU 101 keeps the object 301 three-dimensionally displayed on the display 105 with the pop-out amount being “medium”.

  Referring to FIG. 6C, when the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD1 and less than the threshold ThD2, the CPU 101 sets the pop-out amount to “small” and puts the object 301 on the display 105. 3D display. The CPU 101 keeps the object 301 three-dimensionally displayed on the display 105 with the pop-out amount being “small” unless the distance between the finger 901 and the distance measuring sensor 112 is less than the threshold ThD1.

  With reference to FIG. 6D, when the distance between the finger 901 and the distance measuring sensor 112 is less than the threshold ThD1, the CPU 101 causes the display 105 to display the object 301 two-dimensionally.

  In FIG. 6, the screen transition from FIG. 5D is described as an example, but the screen transition having FIG. 5C or FIG. The pop-out amount is controlled according to the distance from the distance measuring sensor 112.

  As described above, the user can display the object three-dimensionally on the display 105 with the pop-out amount corresponding to the pressing force P by applying the pressing force P to the touch pad 110. In addition, the user can reduce the pop-out amount of the three-dimensionally displayed object by bringing the finger 901 closer to the distance measuring sensor 112 in the three-dimensional display state.

  FIG. 7 is a flowchart showing a part of processing in the electronic apparatus 1. Referring to FIG. 7, in step S <b> 2, CPU 101 determines whether or not a finger touches touch pad 110. When CPU 101 determines that it has touched (YES in step S2), it performs a pointing process in step S4. That is, the CPU 101 performs a process for moving the pointer 309. When CPU 101 determines that it is not in contact (NO in step S2), the process proceeds to step S2.

  In step S <b> 6, the CPU 101 determines whether or not the finger is removed from the touch pad 110. When CPU 101 determines that the user has left (YES in step S6), the process proceeds to step S2. If CPU 101 determines that it is not separated (NO in step S6), it determines in step S8 whether the position of pointer 309 is the position of the object. That is, the CPU 101 determines whether or not the position of the pointer 309 is included in the object display area.

  If CPU 101 determines that it is not the position of the object (NO in step S8), the process proceeds to step S4. If CPU 101 determines that the position is the position of the object (YES in step S8), it determines in step S10 whether or not pressing force P is greater than or equal to threshold value ThP1.

  When CPU 101 determines that it is less than threshold value ThP1 (NO in step S10), the process proceeds to step S4. When CPU 101 determines that it is equal to or greater than threshold value ThP1 (YES in step S10), it determines in step S12 whether or not pressing force P is equal to or greater than threshold value ThP3.

  When CPU 101 determines that the threshold value is ThP3 or more (YES in step S12), in step S14, the pop-out amount is set to “large” and the object is three-dimensionally displayed. If CPU 101 determines that it is less than threshold value ThP3 (NO in step S12), it determines in step S16 whether or not pressing force P is greater than or equal to threshold value ThP2.

  When CPU 101 determines that the threshold value is ThP2 or more (YES in step S16), in step S18, the pop-out amount is set to “medium” and the object is three-dimensionally displayed. If CPU 101 determines that the value is less than threshold value ThP2 (NO in step S16), in step S20, the pop-out amount is set to “small” and the object is displayed three-dimensionally.

  Note that step S12 may be performed after step S8, and step S10 may be performed when NO is determined in step S16. In this case, the CPU 101 may proceed to step S20 if YES in step S10.

  FIG. 8 is a flowchart showing the remaining flow of processing in the electronic apparatus 1. Referring to FIG. 8, in step S <b> 22, CPU 101 determines whether or not the finger has been removed from touch pad 110. If CPU 101 determines that the finger has been released (YES in step S22), it determines in step S24 whether distance D measured by distance measuring sensor 112 is less than threshold value ThD3. When CPU 101 determines that the finger is not separated (NO in step S22), the process proceeds to step S22.

  When CPU 101 determines that distance D is less than threshold value ThD3 (YES in step S24), it determines in step S26 whether distance D is greater than or equal to threshold value ThD2. When CPU 101 determines that distance D is not less than threshold value ThD3 (NO in step S24), the process proceeds to step S24.

  If the CPU 101 determines that the distance D is equal to or greater than the threshold ThD2 (YES in step S26), in step S28, the CPU 101 determines whether or not the amount of popping-out of the object displayed three-dimensionally is “small”. . For example, the CPU 101 may determine whether or not the pop-out amount is “small” based on a flag indicating the pop-out amount state. When CPU 101 determines that distance D is less than threshold value ThD2 (NO in step S26), the process proceeds to step S32.

  If the CPU 101 determines that the amount of popping out of the object is not “small” (NO in step S28), in step S30, the amount of popping out is set to “medium” and the object is displayed on the display 105 three-dimensionally. If CPU 101 determines that the amount of pop-out of the object is “small” (YES in step S28), the process proceeds to step S32. Prior to step S30, if the object has been displayed three-dimensionally with the pop-out amount set to “medium”, no screen transition occurs in step S30.

  In step S32, the CPU 101 determines whether or not the distance D is greater than or equal to a threshold value ThD1. If the CPU 101 determines that the distance D is greater than or equal to the threshold ThD1 (YES in step S32), in step S34, the pop-out amount is set to “small” and the object is three-dimensionally displayed on the display 105. Prior to step S34, if the object is already displayed three-dimensionally with the pop-out amount being “small”, the screen does not change in step S34. If the CPU 101 determines that the distance D is less than the threshold ThD1 (NO in step S32), the CPU 101 switches the object that has been three-dimensionally displayed on the display 105 to two-dimensional display in step S36.

[Embodiment 2]
By the way, in the above, the structure which displays the object selected with the pointer three-dimensionally was demonstrated. In the present embodiment, a configuration will be described in which not only an object is three-dimensionally displayed but a region including a position designated by a pointer is three-dimensionally displayed. Note that an electronic device having the configuration (hereinafter referred to as “electronic device 1A”) has the same appearance and hardware configuration as those of the electronic device 1 (see FIGS. 1 and 2). Therefore, description of the appearance and hardware configuration of electronic device 1A will not be repeated here. The electronic device 1A is different from the electronic device 1 in the program and data stored in the flash memory 104.

  The flash memory 104 stores the above-described threshold values ThP1, ThP2, and ThP3. The flash memory 104 has data (hereinafter referred to as “display control data”) that represents the amount of popping out of the image so that the amount of popping out of the image at the specified pointer position is maximized and the amount of popping out decreases as the distance from the position increases. ) Is further stored. In the display control data, the pressing force and the pop-out amount are further associated with each other so that the value of the pop-out amount of the image increases as the pressing force P increases. Further, in the display control data, the pressing force P and the size of the display area for three-dimensional display are further associated with each other so that the display area for three-dimensional display becomes wider as the pressing force P is higher. The display control data will be described later with reference to FIG.

  Also, the display control data is used to reduce the overall pop-out amount of the popped-out area even when the user brings the finger 901 close to the distance measuring sensor 112 to reduce the pop-out amount of the image. There is a relationship between the distance and the pop-out amount.

  FIG. 9 is a diagram for explaining an example of display control in the electronic apparatus 1A. FIG. 9A is a diagram showing a state in which the pressing force P less than the threshold ThP1 is applied to the touch pad 110. FIG. FIG. 9B is a diagram showing a state in which a pressing force P not less than the threshold ThP1 and less than the threshold ThP2 is applied to the touch pad 110 after FIG. 9A. FIG. 9C is a diagram showing a state in which a pressing force P not less than the threshold ThP2 and less than the threshold ThP3 is applied to the touch pad 110 after FIG. 9A. FIG. 9D is a diagram illustrating a state in which the pressing force P equal to or higher than the threshold ThP3 is applied to the touch pad after FIG. 9A.

  Referring to FIG. 9A, the user moves the pointer 309 to, for example, the nose of the cat 601 by bringing a finger into contact with the touch pad 110 with a pressing force less than the threshold ThP1.

  Referring to FIG. 9B, when CPU 101 determines that pressing force P not less than threshold value ThP1 and less than threshold value ThP2 has been applied to touch pad 110, the CPU 101 sets the pop-out amount to “small” based on the display control data. At least a part of the display area 105 is displayed three-dimensionally. Specifically, the CPU 101 determines a display area for three-dimensional display based on the display control data and the pressing force P. Further, based on the display control data and the pressing force P, the CPU 101 maximizes the amount of projection of the image at the specified pointer position (that is, the maximum when the amount of projection is small), and moves away from the position. Decrease the pop-out amount. That is, the CPU 101 maximizes the amount of protrusion of the cat 601 nose. At that time, in order to improve the visibility, the CPU 101 hides the pointer 309. The same applies to FIGS. 9C and 9D.

  Referring to FIG. 9C, when the CPU 101 determines that the pressing force P not less than the threshold ThP2 and less than the threshold ThP3 has been applied to the touch pad 110, the CPU 101 sets the pop-out amount to “medium” based on the display control data. At least a part of the display area 105 is displayed three-dimensionally. Specifically, the CPU 101 determines a display area for three-dimensional display based on the display control data and the pressing force P. That is, the CPU 101 three-dimensionally displays a display area wider than the three-dimensional display area shown in FIG. Further, based on the display control data and the pressing force P, the CPU 101 maximizes the amount of projection of the image at the specified pointer position (that is, the maximum when the amount of projection is medium), and moves away from the position. Decrease the pop-out amount.

  Referring to FIG. 9D, when CPU 101 determines that pressing force P equal to or greater than threshold ThP3 has been applied to touch pad 110, CPU 101 sets the pop-out amount to “large” based on display control data, and at least displays 105 on display 105. A part of the display area is displayed in three dimensions. Specifically, the CPU 101 determines a display area for three-dimensional display based on the display control data and the pressing force P. That is, the CPU 101 three-dimensionally displays a display area wider than the three-dimensional display area shown in FIG. Further, based on the display control data and the pressing force P, the CPU 101 maximizes the amount of projection of the image at the specified pointer position (that is, the maximum when the amount of projection is large), and moves away from the position. Decrease the pop-out amount.

  FIG. 10 is a diagram simulating the relationship between the display area displayed in three dimensions and the pop-out amount in FIGS. 9B, 9C, and 9D. FIG. 10A is a side view showing the fifth surface 10E side of the electronic apparatus 1A. FIG. 10B is a side view showing the fourth surface 10D side of the electronic apparatus 1A.

  Referring to FIGS. 10A and 10B, the curve C1 is three-dimensionally displayed when a pressing force P not less than the threshold ThP1 and less than the threshold ThP2 is applied to the touch pad 110 (in the case of FIG. 9B). 5 is a graph for explaining the relationship between the display area and the pop-out amount. A curve C2 is for explaining the relationship between the display area and the pop-out amount displayed three-dimensionally when a pressing force P not less than the threshold ThP2 and less than the threshold ThP3 is applied to the touch pad 110 (in the case of FIG. 9C). It is a graph of. A curve C3 is a graph for explaining the relationship between the display area displayed three-dimensionally and the pop-out amount when the pressing force P equal to or greater than the threshold ThP3 is applied to the touch pad 110 (in the case of FIG. 9C). is there.

  As shown by the curves C1, C2, and C3, the CPU 101 increases the pop-up amount of the display area to be displayed three-dimensionally as the pressing force P increases. In addition, as indicated by the curves C1, C2, and C3, the CPU 101 maximizes the amount of jumping out of the image at the specified pointer position, and decreases the amount of popping away from the position. When a certain pressing force is applied, the pop-out amount at the position equidistant from the coordinates (Xa, Ya) is the same.

  In addition, when a pressing force P not less than the threshold ThP1 and less than the threshold ThP2 is applied to the touch pad 110 (in the case of FIG. 9B), the CPU 101 displays a circle region having a diameter R1 in a three-dimensional manner. When the pressing force P not less than the threshold value ThP2 and less than the threshold value ThP3 is applied to the touch pad 110 (in the case of FIG. 9C), the CPU 101 displays a circle region having a diameter R2 (R2> R1) three-dimensionally. When the pressing force P equal to or greater than the threshold ThP3 is applied to the touch pad 110 (in the case of FIG. 9D), the CPU 101 displays a circle region having a diameter R3 (R3> R2) in a three-dimensional manner.

  In the flash memory 104, as the display control data, as shown by the curves C1, C2, and C3, data indicating the pop-out amount displacement and the area size to be displayed in three dimensions is stored in advance. The CPU 101 refers to the data to determine the pop-out amount and the display area range to be displayed three-dimensionally. Note that the display control data may include an arithmetic expression.

  As described above, the electronic device 1A increases the pop-out amount at the position of the pointer, and decreases the pop-out amount as the distance from the position increases. Also, the electronic device 1A sets a wider display area for three-dimensional display as the pressing force P is larger. Furthermore, as with the electronic device 1, the electronic device 1 </ b> A increases the amount of image pop-out as the pressing force P increases.

  In the following, the pop-up mode shown in the curve C1 of FIG. 9B and FIG. 10 is referred to as “first pop-up mode”, and the pop-up mode shown in the curve C2 of FIG. 9C and FIG. 2 ”and the pop-up mode shown by the curve C3 in FIG. 9D and FIG. 10 are referred to as“ third pop-out mode ”.

  FIG. 11 shows a screen in the case where the user gradually moves the finger 901 closer to the distance measuring sensor 112 from a state where the area centered on the position of the pointer is displayed in a three-dimensional manner with the pop-out mode being the “third pop-out mode”. It is a figure showing a transition. That is, FIG. 11 is a diagram showing screen transition from FIG.

It is in a state close to. More specifically, FIG. 11A shows a state where the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD3.

  11B, the user further brings the finger 901 closer to the distance measuring sensor 112 from the state of FIG. 11A, and the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD2 and less than the threshold ThD3. Shows the state. 11C, the user further brings the finger 901 closer to the distance measuring sensor 112 from the state of FIG. 11B, and the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD1 and less than the threshold ThD2. The state is shown. FIG. 11D shows a state in which the user further brings the finger 901 closer to the distance measuring sensor 112 from the state of FIG. 11C and the distance between the finger 901 and the distance measuring sensor 112 is less than the threshold ThD1. Show.

  Referring to FIG. 11A, when the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD3, the CPU 101 determines an area centered on the position of the pointer (a circular area having a diameter R3) as “ The three-dimensional display is continued in the “third pop-out mode”.

  Referring to FIG. 11B, when the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD2 and less than the threshold ThD3, the CPU 101 determines a region (a circle with a diameter R2) centered on the position of the pointer. Area) is displayed in a three-dimensional manner in the “second pop-up mode”. As long as the distance between the finger 901 and the distance measuring sensor 112 is not less than the threshold value ThD2, the CPU 101 continues to display the area in a three-dimensional manner in the “second pop-out mode”.

  Referring to FIG. 11C, when the distance between the finger 901 and the distance measuring sensor 112 is equal to or greater than the threshold ThD1 and less than the threshold ThD2, the CPU 101 determines an area centered on the position of the pointer (a circle with a diameter R1). Area) is displayed in a three-dimensional manner in the “first pop-out mode”. As long as the distance between the finger 901 and the distance measuring sensor 112 is not less than the threshold value ThD1, the CPU 101 continues to display the area in a three-dimensional manner in the “first pop-out manner”.

  With reference to FIG. 11D, when the distance between the finger 901 and the distance measuring sensor 112 is less than the threshold ThD1, the CPU 101 switches the three-dimensional display to the two-dimensional display. When returning to the two-dimensional display, the CPU 101 displays a pointer 309. The user can also determine that the three-dimensional display has been switched to the two-dimensional display by displaying the pointer 309.

  In FIG. 11, the screen transition from FIG. 9D has been described as an example, but the screen transition with FIG. 9C or FIG. The pop-out amount is controlled according to the distance from the distance measuring sensor 112.

  As described above, the user can three-dimensionally display the area centered on the position of the pointer on the display 105 with the pop-out amount corresponding to the pressing force P by applying the pressing force P to the touch pad 110. In addition, the user can reduce the pop-out amount of the three-dimensionally displayed area by bringing the finger 901 closer to the distance measuring sensor 112 in the three-dimensional display state.

  FIG. 12 is a flowchart showing a partial flow of processing in the electronic apparatus 1A. Referring to FIG. 12, in step S <b> 102, CPU 101 determines whether or not a finger touches touch pad 110. When CPU 101 determines that it has touched (YES in step S102), it performs a pointing process in step S104. That is, the CPU 101 performs a process for moving the pointer 309. When CPU 101 determines that it is not in contact (NO in step S102), the process proceeds to step S102.

  In step S <b> 106, the CPU 101 determines whether or not the finger has been removed from the touch pad 110. When CPU 101 determines that the user has left (YES in step S106), the process proceeds to step S102. If CPU 101 determines that it is not separated (NO in step S106), it determines in step S108 whether or not pressing force P is greater than or equal to threshold value ThP1.

  When CPU 101 determines that it is less than threshold value ThP1 (NO in step S108), the process proceeds to step S104. When CPU 101 determines that it is equal to or greater than threshold value ThP1 (YES in step S108), it determines in step S110 whether or not pressing force P is equal to or greater than threshold value ThP3.

  When CPU 101 determines that the threshold value is ThP3 or more (YES in step S110), in step S112, the region centered on the position of the pointer (a circular region having a diameter R3) is three-dimensionally displayed in a third pop-up manner. When CPU 101 determines that it is less than threshold value ThP3 (NO in step S110), it determines in step S114 whether or not pressing force P is greater than or equal to threshold value ThP2.

  Note that step S110 may be performed after step S106, and step S108 may be performed when NO is determined in step S14. In this case, the CPU 101 may proceed to step S118 if YES in step S108.

  FIG. 13 is a flowchart showing the remaining flow of processing in the electronic apparatus 1A. Referring to FIG. 13, in step S <b> 120, CPU 101 determines whether or not the finger has been removed from touch pad 110. When CPU 101 determines that the finger has been released (YES in step S120), CPU 101 determines in step S122 whether distance D measured by distance measuring sensor 112 is less than threshold value ThD3. When CPU 101 determines that the finger has not been removed (NO in step S120), the process proceeds to step S120.

  When CPU 101 determines that distance D is less than threshold value ThD3 (YES in step S122), CPU 101 determines whether or not distance D is greater than or equal to threshold value ThD2. When CPU 101 determines that distance D is not less than threshold value ThD3 (NO in step S122), the process proceeds to step S122.

  If the CPU 101 determines that the distance D is equal to or greater than the threshold ThD2 (YES in step S124), in step S126, a region (circular region having a diameter R1) centered on the position of the pointer in the “first pop-out manner” is obtained. It is determined whether or not three-dimensional display is in progress. For example, the CPU 101 may determine whether or not the pop-up mode is the “first pop-out mode” based on the flag indicating the pop-out mode. When CPU 101 determines that distance D is less than threshold value ThD2 (NO in step S124), the process proceeds to step S130.

  If the CPU 101 determines that the area is not being three-dimensionally displayed in the “first pop-up mode” (NO in step S126), the area centered on the position of the pointer in the “second pop-out mode” in step S128. (Circle region of diameter R2) is displayed on the display 105 three-dimensionally. If CPU 101 determines that the three-dimensional display is not being performed in the “first pop-up mode” (NO in step S126), the process proceeds to step S130. Prior to step S128, if the area centered on the position of the pointer (circular area of diameter R2) is already displayed on the display 105 in the “second pop-up mode” on the display 105, in step S128. No screen transition occurs.

Prior to step S132, if the area centering on the position of the pointer (the circular area having the diameter R1) is already displayed on the display 105 in the “first pop-up mode” on the display 105, the process proceeds to step S132. No screen transition occurs. When CPU 101 determines that distance D is less than threshold value ThD1 (NO in step S130), CPU 101 switches the three-dimensional display to the two-dimensional display in step S134.

<Summary of electronic devices 1 and 1A>
(1) As described above, the electronic devices 1 and 1A are electronic devices capable of three-dimensional display of images. The electronic devices 1 and 1A measure the distance to the CPU 101, the flash memory 104 connected to the processor, the display 105 for displaying an image, the pressure sensor 121 for detecting the pressing force, and the object. The distance measuring sensor 112 is provided. The display 105 is provided on the first surface 10A of the housing 10 of the electronic device 1 or 1A. The pressure sensor 121 is provided on the second surface 10B of the housing 10 that is the back surface of the first surface 10A, and detects a pressing force toward the display 105. When the pressing force is detected, the CPU 101 causes the display 105 to display the image of at least a part of the display area on the display 105 in a three-dimensional manner in a manner of protruding from the display 105. The CPU 101 maintains the three-dimensional display of the image even if the pressing force is not detected after the image is displayed three-dimensionally. The CPU 101 determines whether the distance between the distance measuring sensor 112 and the finger 901 (object) is within a predetermined distance. When the CPU 101 determines that the distance is within the predetermined distance while maintaining the three-dimensional display of the image, the CPU 101 switches the display mode of the image from the three-dimensional display to the two-dimensional display.

  Therefore, when detecting the pressing force, the electronic devices 1 and 1A can display an image of at least a part of the display area on the display 105 in a three-dimensional manner. Therefore, the user can easily perform the switching operation from the two-dimensional display to the three-dimensional display by using the pressing force. Further, the electronic devices 1 and 1A can cause the image of at least a part of the display area on the display 105 to jump out in the direction in which the user has pressed. That is, in the electronic devices 1 and 1A, the direction in which the user applies pressure coincides with the direction in which the image protrudes. For this reason, the switching process to the three-dimensional display according to a user's intuition is realizable.

  Further, the electronic devices 1 and 1A can maintain the three-dimensional display of the image even if the pressing force is not detected after the image is three-dimensionally displayed. Furthermore, the electronic devices 1 and 1A change the display mode of the image to 3 by allowing the user to bring the finger 901 closer to the distance measuring sensor 112 to a predetermined distance while maintaining the three-dimensional display of the image. Switch from 2D display to 2D display. Therefore, the user can return the image displayed three-dimensionally to the two-dimensional display again by moving the finger in the direction of the distance measuring sensor 112.

  (2) The distance measuring sensor 112 is provided on the first surface 10A. Therefore, in a state where the electronic devices 1 and 1A maintain the three-dimensional display of the image, the user moves the finger 901 to a predetermined distance with respect to the distance measuring sensor 112 provided on the same surface as the display 105. By approaching, the three-dimensional display of the image is switched to the two-dimensional display.

  Therefore, the user can return the three-dimensionally displayed image to the two-dimensional image again by moving the finger in the direction opposite to that when the image is three-dimensionally displayed. In this way, when the three-dimensional display is performed and when the three-dimensional display is returned to the two-dimensional display, the direction in which the user moves the finger is opposite. Therefore, the electronic devices 1 and 1A can be intuitively operated by the user.

  (3) The pressure sensor 121 is realized by the touch pad 110 for designating the position of the pointer displayed on the display 105. When the position of the pointer is designated, the CPU 101 causes the image at the position of the pointer and an image around the position of the pointer to be displayed in a three-dimensional manner in a manner that pops out.

  Therefore, the user can designate an image desired to be displayed three-dimensionally with the pointer.

  (4) The flash memory 104 in the electronic device 1 further stores coordinate data representing the display area of the object included in the image. Based on the coordinate data, the CPU 101 determines whether or not the designated pointer position is included in the display area of the object. When the CPU 101 determines that the object is included in the display area of the object, the CPU 101 displays the object in a three-dimensional manner in the above-described manner.

  Therefore, the user can specify an object to be displayed three-dimensionally with the pointer. The object is not limited to the graphic shown in FIG. 5, and may be an icon indicating a file, a folder, or the like, a character string indicating a link destination, or an image.

  (5) The flash memory 104 in the electronic device 1 further stores a data table 41 in which the pressing force P and the popping amount are associated with each other so that the value of the popping amount of the image increases as the pressing force P increases. Yes. Based on the data table 41, the CPU 101 displays the projection amount corresponding to the pressing force P three-dimensionally.

  Therefore, the electronic device 1 increases the amount of protrusion of the object when the pressing force P increases. Thus, since the electronic device 1 increases the pop-out amount not only in the direction of the pressing force but in proportion to the magnitude of the pressure, the control of the pop-out amount according to the user's intuition can be realized. Therefore, the electronic device 1 is excellent in operability for the user.

  (6) As the distance between the distance measuring sensor 112 and the finger 901 becomes shorter, the CPU 101 reduces the amount of jumping out of the object displayed three-dimensionally. Therefore, the electronic device 1 can realize control of the pop-out amount according to the user's intuition.

  (7) The flash memory 104 in the electronic device 1A is used for display control that represents the amount of popping out of the image so that the amount of popping out of the image at the specified pointer position is maximized and the amount of popping out decreases as the distance from the position increases. Stores more data. Based on the display control data, the CPU 101 maximizes the pop-out amount of the image at the specified pointer position, and decreases the pop-out amount as the distance from the position increases.

  Therefore, the user can specify the position with the pointer and press the touch pad 110, thereby maximizing the pop-out amount of the image at the specified position and reducing the pop-out amount as the distance from the position increases.

  (8) In the display control data stored in the electronic device 1A, the pressing force P and the pop-out amount are further associated with each other so that the value of the pop-out amount of the image increases as the pressing force P increases. . Based on the display control data and the pressing force P, the CPU 101 maximizes the pop-out amount of the image at the specified pointer position, and decreases the pop-out amount as the distance from the position increases.

  Therefore, the user can change the pop-out amount of the image displayed by popping out by changing the pressing force P.

  (9) In the display control data stored in the electronic device 1A, the pressing force P and the size of the display area to be displayed three-dimensionally so that the display area to be three-dimensionally displayed becomes wider as the pressing force P is higher. Are further associated. The CPU 101 determines a display area to be three-dimensionally displayed based on the display control data and the pressing force P.

  Therefore, the user can widen the range of the image displayed by popping up by increasing the pressing force P.

  (10) As the distance between the distance measuring sensor 112 and the finger 901 becomes shorter, the CPU 101 reduces the amount of projection of the image at each position in the display area to be displayed three-dimensionally. Therefore, the electronic device 1A can realize control of the pop-out amount according to the user's intuition.

  For example, it may be realized by an input device that has a contact surface for input to be touched by a finger or the like, and the position of the contact surface and the position of the display area of the display 105 correspond one-to-one. As the input device, a device that does not move the pointer, such as an input device constituting a touch panel, may be used. Alternatively, the pressure sensor 121 may be realized by a push button.

  When the pressure sensor 121 is realized by a device having the contact surface, the display area of the display 105 and the shape (shape and size) of the contact surface are preferably the same. Furthermore, it is preferable that the X coordinate value and the Y coordinate value of the display area and the contact surface are the same.

More specifically, when the position is designated by the device, the CPU 101 may display the image at the designated position and the image around the designated position in a three-dimensional manner as described above.

  (3) In the above description, a configuration in which three-dimensional display is performed when the threshold Th1 is provided and a pressing force equal to or greater than the threshold Th1 is applied to the pressure sensor 121 has been described as an example. However, the present invention is not limited to this. . A configuration may be adopted in which three-dimensional display is performed when the user's finger or the like touches the touch pad 110 without providing the threshold Th1.

  (4) In the above description, an example in which three thresholds are provided has been described, but the present invention is not limited to this. In the electronic devices 1 and 1A, it is only necessary to provide a threshold value used for determining switching from the two-dimensional display to the three-dimensional display. That is, the number of threshold values may be one or more. For example, when a plurality of threshold values are set, the pop-out amount may be increased every time the pressing force exceeds each threshold value.

  (5) The electronic devices 1 and 1A are configured so that the pop-out amount v continuously changes (increases) as the pressing force P increases without providing the threshold values Th1, Th2 and Th3 as described above. May be. The electronic devices 1 and 1A may control the pop-out amount v in relation to, for example, v = a × P + b (where a and b are coefficients).

  (6) As described above, only the threshold Th1 is provided without providing the thresholds Th2 and Th3, and the pop-out amount continuously changes (increases when the pressing force P is equal to or greater than the threshold Th1 as the pressing force P increases. ), The electronic devices 1 and 1A may be configured. The electronic devices 1 and 1A may control the pop-out amount v represented by the following expression, for example. Note that a and b are coefficients.

v = a × P + b (Th1 ≦ P)
v = 0 (0 ≦ P <Th1)
(7) The display area to be three-dimensionally displayed in the electronic device 1A is not limited to the circular area. For example, a configuration in which the shape of a display area to be three-dimensionally displayed according to a user input may be set. For example, it is good also as a structure which can be set to a polygon, an ellipse, a star shape, etc. In this case, a plurality of area data may be stored or the area data parameters may be changed.

  (8) In the electronic apparatus 1A, the configuration in which the display area to be displayed three-dimensionally as the pressing force P increases is given as an example. However, the size of the display area to be displayed in three dimensions even when the pressing force P increases. The electronic device 1A may be configured so that is constant.
