Description

  The present invention relates to an electronic device and a display control program.

  Many people are interested in sunrise and sunset in outdoor activities such as mountaineering. Even now, a smartphone application or the like that presents the sunrise time and direction on a map has been proposed. In addition, cameras that display the time and direction of celestial bodies have been proposed (see Patent Document 1).

JP 2011-172102 A

  Since outdoor devices are basically desired to be used hands-free, the direction of sunrise is also displayed on a wearable portable device (so-called wrist device) like a watch rather than a handheld portable device such as a smartphone or camera. It is more convenient to let it go. However, since the size of the display screen of the list device is smaller than that of a smartphone or a camera, the amount of information that can be displayed is limited.

  The present invention has been made in view of the above problems, and some aspects of the present invention provide an electronic device that can intuitively and easily display the orientation of a celestial body such as the sun even in a small display space. An object is to provide a device and a display control program.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following aspects or application examples.

[Application Example 1]
The electronic apparatus according to this application example displays the outgoing direction and the incoming direction of the celestial body using an arc-shaped scale.

  In this way, if an arc-shaped scale is used instead of text to indicate the azimuth, the azimuth's outgoing azimuth and celestial body are similar to general azimuth magnets (those having a cylindrical case, dial and hands). It is possible to inform the user of the direction of the entrance sensuously. Even if a detailed scale is not given to the arc-shaped scale, the user can recognize the azimuth direction and the celestial direction. Accordingly, the space required for displaying the azimuth exit direction and the entry direction of the celestial body can be kept small. Here, the “arc-shaped scale” refers to an arc-shaped coordinate axis. However, this coordinate axis is not limited to the coordinate axis to which the scale is given, and includes the coordinate axis to which the scale is not given and the non-display coordinate axis (transparent coordinate axis).

[Application Example 2]
The electronic device according to this application example performs the display so that the displayed orientation matches the actual orientation.

  Therefore, no matter what direction the user is facing, the outgoing direction of the celestial body and the incoming direction of the celestial body indicate the actual direction. Therefore, for example, even when the user changes the posture in various ways when determining the composition for taking a picture, the user can easily recognize the azimuth direction and the entry of the celestial body.

[Application Example 3]
The electronic apparatus according to this application example displays the direction of the celestial body at the current time together with the outgoing direction and the incoming direction.

  Therefore, the user can grasp the rough movement of the celestial body in the past, the current time, and the future. Also, the user can estimate the approximate time from the current time to the departure time or the entry time by this display.

[Application Example 4]
The electronic apparatus according to this application example displays at least one of the outgoing time and the incoming time together with the outgoing direction and the incoming direction.

  Therefore, the user can accurately know the departure time or the entry time together with the exit direction and the entry direction.

[Application Example 5]
The electronic device according to this application example displays the departure time or the remaining time until the entry time together with the exit direction and the entrance direction.

  In this case, the user can accurately know the time from the current time to the departure time or the entry time.

[Application Example 6]
In the electronic device according to this application example, the angle range from the outgoing azimuth to the incoming azimuth is represented by a partial ring-shaped image.

  Therefore, the user can intuitively know the azimuth angle from the outgoing azimuth to the incoming azimuth. The user can also grasp the approximate length of time that the celestial object can be observed and the approximate length of time that the celestial object cannot be observed.

[Application Example 7]
The electronic device according to this application example obtains the incoming direction and the outgoing direction based on information indicating a position of the electronic device on the earth and information indicating a relative positional relationship of the celestial body with respect to the earth. .

  Accordingly, since the incoming direction and outgoing direction displayed on the electronic device are directions corresponding to the position of the electronic device on the earth, it is possible to present the appropriate incoming direction and outgoing direction for the user. Further, for example, if a table or the like is used as information indicating the relative positional relationship of the celestial body with respect to the earth, it is possible to reduce the amount of calculation for obtaining the incoming azimuth and outgoing azimuth.

[Application Example 8]
The electronic device according to this application example can be attached to a predetermined part of the user.

  Therefore, the user can confirm the azimuth direction and the azimuth direction in a hands-free state.

[Application Example 9]
The predetermined part of the electronic apparatus according to this application example is an arm or a wrist.

  Therefore, the user can use the electronic device with a sense similar to that of a wristwatch or the like.

[Application Example 10]
The electronic device according to this application example performs the display by regarding the 12 o'clock direction of the display screen as the front of the user.

  Therefore, the user can use the electronic device with a sense similar to that of a wristwatch or the like. In addition, even when the posture of the user's arm changes, it is possible to avoid a situation in which the content displayed on the electronic device is difficult to read. Here, the “12 o'clock direction of the display screen” refers to the 12 o'clock direction when the display screen is regarded as a dial of a 12-hour clock.

[Application Example 11]
In the electronic apparatus according to this application example, the celestial body is the sun or the moon.

  Therefore, the user can confirm the sun or moon entering direction and the outgoing direction with the electronic device. Therefore, for example, in photographing the sun, the electronic device can be used when the user determines the composition of the camera. In addition, for example, in observation or photographing of the moon, the display device can be used when the user determines the field of view of the telescope or the composition of the camera.

[Application Example 12]
The display control program according to this application example causes a computer to display the outgoing direction and the incoming direction of an astronomical object on an electronic device using an arc-shaped scale.

  In this way, if an arc-shaped scale is used instead of text to indicate the azimuth, the direction of the celestial body and the direction of the celestial body are similar to those of a general azimuth magnet (having a cylindrical case, dial and hands). The direction of entering can be sensibly notified to the user. Even if a detailed scale is not given to the arc-shaped scale, the user can recognize the azimuth direction and the celestial direction. Accordingly, the space required for displaying the azimuth exit direction and the entry direction of the celestial body can be kept small.

The processing by the processing unit 120 includes data processing for data generated by the GPS sensor 110 or the geomagnetic sensor 140, display control processing for displaying an image on the display unit 170, sound output control processing for outputting sound to the sound output unit 180, and the like. Included _.

  The storage unit 130 includes, for example, one or a plurality of IC memories, and stores data such as a display control program 132, an astronomical calculation table (an example of information indicating the relative positional relationship of celestial bodies with respect to the earth) 131, and the like. A ROM and a RAM serving as a work area for the processing unit 120 are included.

  The operation unit 150 includes, for example, a button, a key, a microphone, a touch panel, and the like, and performs a process of converting an instruction from the user into an appropriate signal and sending it to the processing unit 120.

  The sound output unit 180 includes, for example, a speaker, a buzzer, and a vibrator, and generates various sounds (or vibrations) in accordance with instructions from the processing unit 120.

[Basic operation of electronic devices]
The processing unit 120 operates as follows according to the display control program 132, for example.

  First, the processing unit 120 performs astronomical calculation according to time data (year, month, day, hour, minute, second) generated by the time measuring unit 160 and positioning data (latitude, longitude) generated by the GPS sensor 110. By referring to the table 131, (1) today's sunrise direction, (2) today's sunset direction, (3) today's (current time) day direction, (4) today's sunrise time, (5 ) Find the sunset time etc. for today.

  Further, the processing unit 120 obtains (6) the current attitude of the electronic device 1 (attitude with respect to the earth axis) based on the geomagnetic data generated by the geomagnetic sensor 140.

  Next, the processing unit 120 (1) Today's sunrise direction, (2) Today's sunset direction, (3) Current day's direction, (4) Today's sunrise time, (5) Today's sunset time (6) Image data indicating the current attitude of the electronic device 1 (attitude with respect to the ground axis) and (7) the current time are created.

  Next, the processing unit 120 sends the created image data to the display unit 170, so that (1) today's sunrise orientation, (2) today's sunset orientation, (3) current day orientation, ( 4) The display unit 170 displays an image showing the sunrise time on today, (5) the sunset time on today, (6) the attitude of the electronic device 1 (attitude with respect to the earth axis) at the present time, and (7) the current time.

  Here, in the astronomical calculation table 131, for example, for each combination of date and positioning position (latitude, longitude), (1) today's sunrise direction, (2) today's sunset direction, (3) The current day direction, (4) today's sunrise time, (5) today's sunset time, and the like are stored. In addition, the astronomical calculation table 131 stores (3) the azimuth of the current day for each combination of year / month / day time and positioning position (latitude, longitude), for example. The astronomical calculation table 131 stores similar information about celestial bodies other than the sun (such as the moon and Venus) for each celestial body.

  That is, the processing unit 120 sets the sunset based on the positioning data (an example of information indicating the position of the electronic device 1 on the earth), the astronomical calculation table 131 (an example of information indicating the relative positional relationship of the celestial body with respect to the earth), and the like. Azimuth, sunrise azimuth, etc.

  Here, the processing unit 120 uses the astronomical calculation table 131 in order to obtain the sunrise direction today, the sunset direction today, the current day direction, the sunrise time today, the sunset time today, and the like. However, the information used by the processing unit 120 may be a calculation formula instead of a table, or a combination of a table and a calculation formula. Since the contents of the calculation (astronomical calculation) for obtaining the azimuth of the sunrise, the sunset azimuth, the azimuth of the current day, and the like are well known, description thereof will be omitted.

[Display screen]
FIG. 3 is an example of a screen (display screen) that the processing unit 120 displays on the display unit 170. Here, it is assumed that the outline of the display screen is circular, and basically a binary monochrome screen (a combination of white and black, a combination of gray and black, a combination of gray and white, two different brightnesses) Assume that the display screen is composed of a combination of gray, etc.). However, in each figure, the color of the relatively bright portion and the color of the relatively dark portion may be reversed. In addition, the luminance value of each part on the display screen does not always completely match the brightness (luminance value) of each part shown in the figure.

  First, as illustrated in FIG. 3A, the processing unit 120 displays the sunrise direction and the sunset direction using an arc-shaped scale. When the display screen is small, it may be desirable that the arc-shaped scale is not graduated to avoid complicated screen design. Therefore, the processing unit 120 of the present embodiment uses the contour of the circular display screen and displays the contour as an arc-shaped scale without a scale.

  In the example of FIG. 3A, an image (north needle image) 17A indicating the north direction is displayed together with the sunrise direction and the sunset direction. That is, the sunrise direction, sunset direction, and north needle image 17A are displayed on one screen. Also, in FIG. 3A, reference numeral 17C denotes a text image “0 °” indicating the azimuth angle of the 12 o'clock direction of the display screen. That is, the example shown in FIG. 3A is an example when the 12 o'clock direction of the display screen matches the north hand.

  Here, the “12 o'clock direction of the display screen” refers to the 12 o'clock direction when the display screen is regarded as a dial of a 12-hour clock.

  Further, the partial ring-shaped image indicated by reference numeral 17B in FIG. 3A represents an angle range (azimuth angle range) from the azimuth of sunrise to the azimuth of sunset with an arc-shaped scale. One end 17B-1 of the partial ring-shaped image 17B indicates the sunrise direction, and the other end 17B-2 of the partial ring-shaped image 17B indicates the sunset direction.

  In addition, when the attitude of the electronic device 1 with respect to the ground axis changes, the processing unit 120 rotates the display direction as shown in FIG. 3B, for example, so that the displayed orientation always matches the actual orientation. Let The example shown in FIG. 3A is an example when the azimuth angle in the 12 o'clock direction of the display screen is 0 °, whereas the example shown in FIG. 3B is the 12 o'clock direction of the display screen. This is an example when the azimuth angle is 260 °. That is, the processing unit 120 always matches the displayed orientation with the actual orientation. Note that the “match” here is not limited to a perfect match, and may be due to, for example, an error derived from the geomagnetic sensor 110, an error generated in the process of calculating the attitude of the electronic device 1 with respect to the earth axis, or display restrictions on the display unit 170. Display deviation is allowed.

  Further, the processing unit 120 displays the azimuth of the day at the present time (current time) as shown in FIGS. 4A and 4B together with the partial annular image 17B (that is, the direction of sunrise and the direction of sunset). You can also. In the example of FIGS. 4A and 4B, a notch part (non-display part, missing part) 17G is provided in a part of the partial ring-shaped image 17B, and the notch part 17G in the arc-shaped scale is provided. Indicates the azimuth of the current day. In this case, the user can simultaneously confirm the three directions of the sunrise direction, the sunset direction, and the current day direction.

  Further, as shown in FIGS. 3A and 3B, the processing unit 120, for example, “14:20” text image 17F indicating the current time, and “5:17” text indicating the sunrise time, for example. An image 17E and a text image 17D of “18:22” indicating the sunset time, for example, are displayed together with the partial ring-shaped image 17B (that is, the sunrise direction and the sunset direction).

  Therefore, the user can recognize the remaining time from the present time to sunrise or sunset. Although not shown, the processing unit 120 calculates the remaining time until the sunrise time or sunset time, and generates a text image (not shown) indicating the time as the partial annular image 17B (that is, the sunrise direction and sunset). May be displayed together. That is, the processing unit 120 may perform a countdown display until sunrise or sunset.

  Further, the processing unit 120 performs display by regarding the 12 o'clock direction of the display screen as the front of the user. For example, even when the posture of the electronic device 1 is changed as shown in FIGS. 3A and 3B, the processing unit 120 displays the text so that the user can always see the correct posture. .

1-2. Note that the display screen is not limited to the one shown in FIG. 3 or FIG. 4. For example, FIG. 5 (A), FIG. 5 (B), FIG. 5 (C), FIG. D), FIG. 5 (E), FIG. 5 (F), and FIG. 6 may be modified.

  In the example shown in FIG. 5A, a plurality of marks arranged along an arc-shaped scale are used instead of the partial annular pattern. In FIG. 5A, the symbol a indicates the sunset direction, the symbol b indicates the sunrise direction, and the symbol c indicates the current day direction. That is, in the example shown in FIG. 5A, the angle range from the sunrise direction to the sunset direction is shown by the plurality of mark arrangement ranges a to b, and the mark is not displayed in a part c of the arrangement ranges a to b. To indicate the current direction of the day. It should be noted that a similar function may be obtained by giving a color different from other marks to some marks instead of hiding some marks. Various shapes such as a circle and a polygon can be adopted as the shape of each mark.

  In the example shown in FIG. 5B, a plurality of marks scattered on the arc-shaped scale are used instead of the partial ring-shaped pattern. In FIG. 5B, the mark indicated by the symbol a indicates the sunset direction, the mark indicated by the symbol b indicates the sunrise direction, and the mark indicated by the symbol c indicates the current direction of the day. ing. In other words, in the example shown in FIG. 5B, the azimuth of sunrise, the azimuth of sunset, and the azimuth of the current day are indicated by three scattered marks. It should be noted that a color different from that of other marks may be given to the mark indicating the azimuth of the current day. Various shapes such as a circle and a polygon can be adopted as the shape of each mark.

  In the example shown in FIG. 5C, a pair of curved teardrop-shaped images and one dot mark are used instead of the partial annular image. In FIG. 5C, the end a of one teardrop-shaped image indicates the sunset direction, the end b of the other teardrop-shaped image indicates the direction of sunrise, and the dot mark c indicates the current time. Shows the direction of the day. In addition, you may give the color different from a pair of teardrop type image with respect to the dot mark c which shows the azimuth | direction of the present day.

  In the example shown in FIG. 5D, a fan-shaped image is used instead of the partial ring-shaped image. In FIG. 5D, one end portion a in the circumferential direction of the fan-shaped image indicates the sunset direction, and the other end b indicates the sunrise direction. Moreover, a notch c is provided in a part of the fan-shaped image, and the notch c indicates the azimuth of the current day. In the example shown in FIG. 5D, the depth of the notch c in the radial direction is not limited to the depth shown in FIG.

  The example shown in FIG. 5E uses a triangular symbol instead of a mark in the example shown in FIG. 5B. The direction of the apex of the triangle symbol faces the arc-shaped scale side (that is, the contour side of the circular display screen). In FIG. 5E, the triangle symbol indicated by symbol a indicates the sunset direction, the triangle symbol indicated by symbol b indicates the sunrise direction, and the triangle symbol indicated by symbol c indicates the current day. Pointing to direction. In addition, you may give the different color from the other triangular symbols with respect to the triangular symbol which shows the azimuth | direction of the present day.

  The example shown in FIG. 5 (F) uses a text image instead of a mark in the example shown in FIG. 5 (B). In the example shown in FIG. 5F, a text image representing the time is used instead of the mark. In the example shown in FIG. 5B, a text image representing the azimuth angle may be used instead of the text image representing the time. Moreover, you may give the color different from another text image with respect to the text image which shows the azimuth | direction of the present day.

  In the above description, it is assumed that the contour of the display screen is circular, and the outermost periphery of the display screen is used as an arc-shaped scale. However, the contour of the display screen of the display unit 170 is also rectangular or square. A similar screen design can be employed.

  For example, when the display screen is rectangular as shown in FIG. 6, a circular display area A1 is provided in the display screen, and the display area A1 is shown in any of FIG. 3, FIG. 4, and FIG. The same display as that of the image may be performed. Further, when the display screen is rectangular, a gap is formed between the circular display area A1 and the outline of the display screen. For example, as shown in FIG. It is good. Thus, if the display destination of some text images is removed from the display area A1, the contents of the display area A1 can be simplified. In FIG. 6, reference numeral 1000 indicates an electronic device, reference numeral 1170 indicates a display screen of a display unit mounted on the electronic device 1000, and reference numeral 1300 indicates the electronic device 1000. A wearing tool (for example, a watch belt) to be worn on the user's wrist, and reference numeral 1200 denotes an operation unit (for example, a crown-shaped operation unit) mounted on the electronic apparatus 1000.

  In addition, the electronic device 1 of the present embodiment may allow the user to select a screen design and display items. For example, the processing unit 120 may display the sunset direction and the sunrise direction according to a design selected in advance by the user among the plurality of screen designs illustrated in FIGS. 3, 4, and 5. In addition, the processing unit 120 has several predetermined display items such as (1) current time, (2) sunset time, (3) sunrise time, (4) remaining time, and (5) 12:00 direction. Items that are not selected by the user among the azimuth angles may be hidden. The design or item selection by the user is performed via the operation unit.

  As a display mode of the electronic apparatus 1 of the present embodiment, a compass mode may be provided in addition to the sunrise / sunset azimuth display mode and the moon rise / moon direction display mode. The compass mode is a mode that exhibits the same function as a general compass (having a cylindrical case, dial, and hands). The display screen in the compass mode corresponds to, for example, the display screen shown in FIG. 3 in which the partial annular image 17B is omitted.

2. As described above, the electronic apparatus 1 according to the embodiment has an arcuate scale for the sunrise azimuth (an example of the celestial body's outgoing azimuth) and the sunset azimuth (an example of the celestial body's incoming azimuth). (See FIGS. 3 and 4).

  In this way, if an arc-shaped scale is used instead of text to indicate the azimuth, the azimuth of sunrise (an example of the azimuth of the celestial body) and the sunset azimuth (the azimuth of the celestial body), as with a normal compass Example) to the user. Moreover, even if the detailed scale is not given to the arc-shaped scale, the user recognizes the sunrise direction (an example of the direction of the celestial object) and the sunset direction (an example of the direction of the celestial object). Is possible. Therefore, the space required for displaying the sunrise direction (the direction from which the celestial body emerges) and the sunset direction (the direction from which the celestial body has entered) can be kept small. In addition, when the arc-shaped scale is used, it is easier to understand than when the text is used. Therefore, even if the user omits the confirmation of the instruction manual of the electronic device 1, the display content of the electronic device 1 is displayed. It is unlikely to be mistaken. Therefore, the electronic device 1 is easy to use for users who are not accustomed to the operation of the electronic device 1, users who want to omit reading fine characters, users who want to omit reading instructions, and the like.

  In addition, the electronic apparatus 1 according to the embodiment performs display so that the displayed orientation matches the actual orientation (FIGS. 3A, 3B, 4A, and 4B). ).

  Therefore, no matter what direction the user goes, the sunrise direction (an example of the direction of the celestial object) and the sunset direction (an example of the direction of the celestial object) always indicate the actual direction. Thus, for example, when determining the composition of photography, even if the user changes the posture in various ways, the direction of sunrise (an example of the direction of the celestial body) and the direction of sunset (the direction of the celestial body) Can be easily recognized by the user (that is, it is considered that there is no possibility that the user mistakenly recognizes).

  Further, the electronic apparatus 1 according to the embodiment displays the azimuth of the day (an example of a celestial body) at the present time (current time) together with the outgoing azimuth and the incoming azimuth (see reference numeral 17G in FIG. 4).

  Therefore, the user can grasp the rough movement of the day (an example of a celestial body) in the past, the present, and the future. The user can also estimate the approximate time from the current time to the departure time or the entry time by this display.

  In addition, the electronic device 1 according to the embodiment displays at least one of the outgoing time and the incoming time together with the outgoing azimuth and the incoming azimuth (see symbols 17D and 17E in FIG. 3).

  Therefore, the user can accurately know the departure time or the entry time together with the exit direction and the entry direction.

  In addition, the electronic device 1 according to the embodiment can also display the departure time or the remaining time until the entry time together with the exit direction and the entrance direction (not shown).

  In this case, the user can accurately know the time from the current time to the departure time or the entry time.

  Moreover, the electronic device 1 according to the embodiment represents an angle range from the outgoing azimuth to the incoming azimuth by a partial ring-shaped image (see FIGS. 3 and 4).

  Therefore, the user can intuitively know the azimuth angle from the outgoing azimuth to the incoming azimuth. In addition, the user can grasp the approximate length of sunshine time (the length of time in which celestial bodies can be observed), the approximate length of night time (the length of time in which celestial bodies cannot be observed), and the like.

  In addition, the electronic device 1 according to the embodiment includes positioning data (an example of information indicating the position of the electronic device 1 on the earth) and an astronomical calculation table 131 (an example of information indicating a relative positional relationship of the celestial body with respect to the earth). Based on the above, the incoming direction and the outgoing direction are obtained.

  Accordingly, since the incoming direction and outgoing direction displayed on the electronic device 1 are directions corresponding to the position of the electronic device on the earth, the appropriate incoming direction and outgoing direction can be presented to the user. Further, if the astronomical calculation table 131 is used as information indicating the relative positional relationship of the celestial body with respect to the earth, the amount of calculation for obtaining the incoming azimuth and outgoing azimuth can be reduced.

  Moreover, the electronic device 1 according to the embodiment can be attached to a predetermined part of the user.
