Description

  The present invention relates to an astrophotography support apparatus, an astrophotography support method, and a program technique.

  In recent years, a photograph is taken by a device such as a digital camera at a predetermined interval time (hereinafter referred to as a shooting interval), and the movement of a moving subject is multiplexed by composing the taken still images. A technique of superimposing on one image is used. Such a photographing method is called interval photographing.

  When performing interval shooting, a camera using a silver salt film continuously captures the movement of the subject on this film by performing multiple exposures on a single film (one film area) at a predetermined shooting interval. be able to. With digital cameras, it is easy to process image data, so it is not common to perform multiple exposures on a single film (single data) like a silver salt film, and multiple images were taken. It is common to multiplex image data in image processing.

  In interval shooting, it is common to perform camera shooting for a long time by fixing a camera device or a smartphone on a tripod or the like (Patent Document 1). In interval shooting, for example, amateur astronomers and camera enthusiasts can capture a celestial body as a moving subject while keeping a landmark object as a fixed subject within the angle of view. It has become popular.

  Hereinafter, an example in which the present invention is applied to a portable information terminal device as an astronomical photography support device will be described. Note that the astrophotography support device in the present invention is not limited to the portable information terminal device, and it is needless to say that a wide variety of terminal devices having functions necessary for the present invention are included.

[Network configuration]
First, a portable information terminal device will be briefly described with reference to FIG. The terminal device 10 has a communication function, and is connected to various server devices 30 via a wireless or wired network 20 such as the Internet. As shown in FIG. 1, a plurality of terminal devices 10 such as terminal devices 10 a, 10 b,..., 10 c can be connected to the server device 30 via the network 20. Hereinafter, the terminal devices 10a, 10b,..., 10c will be described as the terminal device 10 as a single device for convenience.

  The terminal device 10 receives various services and application programs from the server device 30 and can download data and programs. In the following, when describing an example of the present invention, an application program is downloaded to the terminal device 10 and the description is executed in such a manner that the application program is executed. However, the application program is not limited to the downloaded application program, and is stored in the terminal device 10 in advance. Needless to say, it may be executed by a program that is implemented, or may be realized by hardware processing.

[Hardware configuration]
Next, the external appearance of the terminal device 10 will be briefly described with reference to FIG. As shown in FIG. 2, the terminal device 10 includes a housing 11, a display 12, a touch panel 13, a hardware key 14, a camera 15, and the like.

  Next, the internal configuration of the terminal device 10 will be briefly described with reference to FIG. As shown in FIG. 3, the terminal device 10 includes a CPU (Central Processing Unit) 51, an internal memory 52, an external memory 53, an orientation sensor 54, a GPS (Global Positioning System) sensor 55, an acceleration sensor 56, and the like. The wireless communication unit 57, the display 12, the touch panel 13, the hardware key 14, the camera 15, and the atmospheric pressure sensor 16 described in FIG. 2 are connected through a system bus.

  Next, each part of the terminal device 10 will be described in detail.

  The casing 11 is a case that constitutes an outer shell of the terminal device 10 and incorporates each part, and is formed of various members such as resin, metal, and carbon fiber.

  The display 12 constitutes a display unit of the terminal device 10 and can display characters and images. As the display 12, a liquid crystal display, an organic EL (Electro Luminescence) display, etc. can be used. It goes without saying that various devices suitable for displaying a later-described celestial sphere image can be used for the display 12.

  The touch panel 13 constitutes one of the input units of the terminal device 10 and is formed so as to overlap with the display 12 so as to receive an input operation from the user. The touch panel 13 has a structure in which matrix-shaped transparent electrodes are superposed, and the display can be performed by a user's pressing operation, tapping operation, hovering operation (non-contact operation) or the like based on the electric resistance or capacitance between the electrodes. By performing an operation of tracing the image displayed in FIG. 12 with a user's finger or the like, an input operation from the user can be detected.

  Note that various touch operations such as a tap operation, a slide operation, a flick operation, a pinch-in / out operation, and a multi-touch operation can be used as touch panel operations. Although details will be described later as operations in this embodiment, a tap operation is used for a selection operation, a slide operation is used for a time and position change operation, and a pinch-in / out operation is used for an enlargement / reduction operation. Shall. Note that the operation method can be set as appropriate, but the above-described operation example is most preferable in order to enable the user's intuitive operation. Since the operation method is a general-purpose technique, a detailed description is omitted.

  The hardware key 14 constitutes one of the input units of the terminal device 10 and can accept an input operation from the user such as a pressing operation. The hardware key 14 is used in an input operation mode different from that of the touch panel 13, and functions are assigned to a single operation such as a mode switching operation and a power operation, and are used for each application program.

  The camera 15 constitutes one of the input units of the terminal device 10 and can take a picture. The camera 15 includes an image sensor such as an arrayed CCD (Charge Coupled Device) sensor and a CMOS (Complementary Metal Oxide Semiconductor) sensor, and a lens, but is not described in detail because it is a general-purpose technology. The camera 15 can also accept a user's input operation by so-called motion capture technology that captures the user's actions by photographing the user himself / herself. The camera 15 may have an interval shooting function that is controlled by the CPU 51 in accordance with an input operation from the user. In this case, interval shooting can be performed also by the terminal device 10 without using an interval shooting function by the camera device, which will be described later.

  The atmospheric pressure sensor 16 measures atmospheric pressure, and for example, an electrostatic device or a vibration type electronic device can be used. It is also possible to calculate the altitude by measuring the pressure difference based on the altitude difference of the terminal device 10.

  The CPU 51 constitutes one of the control units of the terminal device 10 and is a control unit that controls each component inside the terminal device 10 together with another controller (not shown). The CPU 51 is connected to the internal memory 52, the external memory 53, the azimuth sensor 54, the GPS sensor 55, the acceleration sensor 56, the wireless communication unit 57, the display 12, the touch panel 13, the hardware key 14, the camera 15, the atmospheric pressure sensor 16 and the like through the internal bus. Connected with.

  The CPU 51 can appropriately control each component based on an application program stored in the internal memory 52 or the external memory 53. In the example of the present invention, a process for generating and displaying a celestial sphere image can be performed.

  The internal memory 52 and the external memory 53 constitute a storage unit of the terminal device 10, and are constituted by, for example, a nonvolatile semiconductor memory, and can store various application programs and data. In particular, the internal memory 52 is a storage unit built in the terminal device 10 and stores an operating system and a core program. The external memory 53 is detachable from the terminal device 10, and an application program and data stored by the external device may be attached to the terminal device 10 and used. In the example of the present invention, the storage location of the application program and data is not particularly specified for the internal memory 52 and the external memory 53, but it goes without saying that they may be properly used according to the system.

  The direction sensor 54 is configured to detect the direction of the terminal device 10, and for example, a geomagnetic sensor or a gyro sensor can be used. As will be described later, the azimuth sensor 54 can add detected azimuth information when displaying a celestial sphere image on the display 12, or can be used for generating a celestial sphere image, calculating a trajectory of a celestial body, or the like.

  The GPS sensor 55 is configured to detect the current position of the terminal device 10 on the earth, and can perform triangulation by receiving a plurality of radio waves from GPS satellites to detect the latitude and longitude of the terminal device 10. As will be described later, the GPS sensor 55 can add detected position information when displaying a celestial sphere image on the display 12, or can be used for generating a celestial sphere image, calculating a trajectory of a celestial body, or the like.

  The acceleration sensor 56 is configured to detect the tilt of the terminal device 10 and can use various methods such as an optical method, a mechanical method, and a semiconductor method. In the example of the present invention, it is preferable to use a semiconductor type having a smaller and simpler configuration.

  The wireless communication unit 57 is configured to communicate with the terminal device 10 and a wireless base station (not shown), and includes a transmission / reception antenna, a modulation / demodulation circuit, and the like. The wireless communication unit 57 communicates with the wireless base station and enables communication between the terminal device 10 and the server device 30 via the network 20. Since the wireless communication unit 57 communicates with a wireless base station (not shown), the position of the terminal device 10 can be indirectly detected based on the position information or cell information of the wireless base station. When the information of the sensor 55 cannot be used, position information can be obtained as alternative information. In the example of the present invention, the configuration in which the GPS sensor 55 is omitted is not described, but it goes without saying that the GPS sensor 55 can be omitted.

  In this configuration, illustration and description are omitted, but the network connection method is not limited to the wireless method, and does not hinder the wired method for network connection. Therefore, it goes without saying that a configuration for performing network connection by direct cable connection other than the wireless communication unit 57 may be provided.

  The terminal device 10 can detect the azimuth, position, and tilt of the terminal device 10 based on information from the azimuth sensor 54, the GPS sensor 55, and the acceleration sensor 56. It can be used as current location information when calculating the celestial sphere image 100, and the accurate celestial sphere image 100 can be described and displayed.

[Display]
Next, each function and operation will be described based on an image displayed on the display 12 of the terminal device 10.

  The terminal device 10 starts a control application program under the control of the CPU 51 based on an input operation to the touch panel 13 or the like, and displays a celestial sphere image 100 on the display 12 as shown in FIG. The terminal device 10 can support interval shooting of astronomical photographs by a user performing an input operation on the touch panel 13 based on the displayed celestial sphere image 100.

  The celestial sphere image 100 includes a red meridian 101, a declination line 102, an interval image mode button 103, a parameter display image 104, an orientation auxiliary image 105, a camera field angle auxiliary frame 106, a constellation line 107, a constellation name 108, an astronomical name 109, and a Messier object. 110, camera view angle center target 111, building image 112, horizon 113, azimuth 114, moving celestial body 115, moving celestial orbit line 116, time slider button 130, slider line 131, time information 132, interval image display button 134, setting A button 145, a camera angle of view vertical / horizontal switching button 146, a large celestial body magnification setting button 147, a star, a planet, a Messier celestial body, and the like (not shown) are included.

  Here, in this embodiment, the celestial sphere refers to a virtual spherical surface at an infinite distance in order to represent the direction of the celestial body seen from the earth. In addition, ascension and declination indicate the latitude and longitude on the celestial sphere. The celestial sphere image 100 is an image obtained by developing a star map on which information such as each celestial body and the direction described above is displayed on the celestial sphere.

  The ecliptic meridian 101 and the declination meridian 102 have been defined above, but are lines for displaying the ecliptic and declination on the celestial sphere in an easy-to-understand manner, and may be switched between display and non-display as necessary.

  The interval image mode button 103 is displayed as a camera-type icon, and calls an interval image setting screen for inputting information necessary for performing interval shooting of astronomical photographs by a user's tap operation on the touch panel 13. It has a function.

  As shown in FIG. 5, the parameter display image 104 displays, for example, an interval shooting, a shooting location, a shooting altitude (° unit) indicating the camera tilt, and a shooting direction (° unit) indicating the camera direction. Information window.

  As shown in FIG. 4, the parameter display image 104 is displayed so that a celestial body or the like displayed on the back portion can be confirmed by the transmission process. The parameter display image 104 may not be subjected to the transparency process, but it is preferable that the camera view angle auxiliary frame 106 described later is displayed in an overlapping manner. The camera view angle auxiliary frame 106 is a mark that serves as a reference when determining the camera view angle to be shot, and is not preferably hidden.

  The azimuth auxiliary image 105 is an auxiliary image for explaining which part of the celestial sphere image 100 corresponds to the actual celestial sphere. As shown in FIG. , Zenith 302, horizon 303, and orientation 304. Since the size of the azimuth auxiliary image 105 is smaller than that of the celestial sphere image 100, the azimuth 304 is alphabetized because there is a possibility that it will be collapsed if it is represented in kanji. Needless to say, the azimuth 304 may use kanji characters or symbols as long as the resolution of the display panel 12 permits.

  As shown in FIG. 4, the direction auxiliary image 105 is displayed so that a celestial body or the like displayed on the back portion can be confirmed by the transmission process. Although the azimuth assist image 105 may not be subjected to the transmission process, it is preferable that the camera view angle assist frame 106 described later is displayed in an overlapping manner. The camera angle-of-view auxiliary frame 106 is a mark that serves as a reference when determining the angle of view for photographing, and is not preferably hidden.

  Here, since the display panel 12 has a finite physical size that can be displayed, it is difficult to represent the entire celestial sphere, and the celestial sphere image 100 displays a very small area of the celestial sphere. Stay. Therefore, the azimuth assistance image 105 is provided so as to provide azimuth information of a wider area and facilitate confirmation from the user which direction the celestial sphere image 100 indicates.

  Here, the zenith refers to a point on the celestial sphere that is directly above the observer. More precisely, it is a point indicating a position at an elevation angle of 90 degrees from the horizon. The zenith 302 is a mark indicating which position on the celestial sphere is the zenith based on the time information, and it is possible to easily visually recognize in which region the celestial sphere image 100 is located on a wide range of celestial spheres. Is displayed.

  In addition, the azimuth assist image 105 is displayed at a fixed position without moving in the celestial sphere image 100. In the example of the present invention, the display position of the direction auxiliary image 105 is fixed to the upper right of the celestial sphere image 100 in the drawing. The azimuth assist image 105 may be displayed in another area or may be moved to an arbitrary position of the user.

  The camera angle-of-view auxiliary frame 106 is a frame line indicating the angle of view on the celestial sphere according to the focal length of the lens of the camera device, and changes in size depending on the set focal length of the lens. That is, when a wide-angle lens is used, the focal length is set short, and the frame line shows a large range on the star chart. On the other hand, when a telephoto lens is used, the focal length is set long, and the frame line shows a small range on the star chart.

  In displaying the camera angle assist frame 106, it is known that the angle of view differs depending on the relationship between the focal length of the lens of the camera device and the size of the image sensor of the camera device. Therefore, the angle of view assuming a so-called full-size image sensor having a size equivalent to a 35 mm silver salt film is displayed as the camera angle-of-view auxiliary frame 106 by default. Note that image sensors of various sizes such as APS-C size, which is a smaller size, are also on the market. Accordingly, the manufacturer name, model, etc. of the camera device may be input and displayed as the camera field angle auxiliary frame 106 based on the size of the image sensor unique to the camera. In this case, even a user who does not know the size of the image sensor can know a more accurate angle of view.

  Here, the camera angle assist frame 106 displays only the four corners of the angle of view and the center of the four sides constituting the angle of view, and does not display all the frame lines. The solid line portion shown in FIG. 4 corresponds to this, and the portion indicated by a broken line is only shown for reference. This is a display method for preventing the contents of the celestial sphere image 100 from becoming difficult to see due to an increase in the number of drawn lines in the celestial sphere image 100 and displaying the field of view clearly. Needless to say, you can do it.

  In addition, a cross-shaped camera field angle center target 111 is displayed at the center of the camera field angle auxiliary frame 106. The camera angle-of-view center target 111 is a mark indicating the center of the angle of view and is not particularly limited to a cross shape. However, if the center of the angle of view can be easily described, the shape of the target may be changed as appropriate. Good.

  In FIG. 4 and subsequent figures, the shape of the camera view angle auxiliary frame 106 is not completely rectangular on the celestial sphere image 100 but is distorted in a pincushion shape when the celestial sphere information is developed into a planar image. It reproduces the distortion of the star chart and does not take into account various aberrations caused by the lens. However, it goes without saying that it is also possible to express a more precise camera angle of view in consideration of lens aberration by inputting lens characteristics.

  In FIG. 4, the camera angle-of-view auxiliary frame 106 displays the four corners and the central part of the four sides forming the angle of view as solid lines and the others as broken lines, but the celestial sphere image 100 is complicated. Therefore, only the solid line portion necessary for determining the camera angle of view is displayed, and the broken line portion is omitted in the following drawings. In addition, since the important part in actually determining the angle of view is the solid line part, the broken line part may not be displayed.

  By displaying the camera angle assist frame 106, the user can easily visually understand that each celestial body and the building image 112 displayed in the frame can be taken.

  The constellation line 107 is an image of a constellation in which the stars constituting the constellation displayed on the celestial sphere image 100 are connected and displayed, and a picture associated with the name of the constellation may be displayed. In the form, in order to give priority to the processing speed of the image calculation, a simple display is made by simply connecting the main stars in the constellation with straight lines.

  The constellation name 108 displays the constellation name in characters for a user who does not know what the constellation line 107 alone is. In particular, when the constellation line 107 only connects the main stars in the constellation with straight lines, it is difficult for the user to have an image of the constellation. Can be presented easily.

  The celestial name 109 displays the names of bright celestial bodies such as first-class stars and second-class stars as main stars, and these stars can be used as a guide when searching for stars in the actual night sky. Since it is often used, it becomes a reference when the user observes the starry sky. Therefore, by displaying the reference celestial body name, it becomes easy to grasp the position of the starry sky of the user.

  The Messier celestial body 110 is a catalog of major celestial bodies such as nebulae, star clusters, galaxies, etc., and indicates those numbered as M1,..., M10. In particular, the Messier celestial object is often a subject because it has a characteristic spread compared to other celestial objects, and whether or not the Messier celestial object is displayed in the celestial sphere image 100 to enter the camera angle of view during interval shooting. Can be known by the user.

  The Messier celestial body 110 is simplified and thinned out in FIG. 4, but it is not only the main Messier celestial body but also a nebula, galaxy, star cluster, etc. with NGC (New General Catalog) number. There may be. Any celestial body is a major target for astrophotography, and whether or not it enters the angle of view during interval shooting is a very important judgment material for the user.

[Interval image setting screen]
Here, the interval image setting screen will be described. When the user taps the interval mode button 103 shown in FIG. 4, an interval image setting screen 400 is displayed on the display 12 as shown in FIG. 7.

  The interval image setting screen 400 includes a slide button 401 for switching on / off of the interval image mode, a setting set selection menu 402 for selecting a setting set, a shooting date / time menu 403 for setting shooting date / time, and a shooting location as an observation location. A shooting location menu 404 to be set, an altitude menu 405 to set the altitude of the shooting location as the observation location, a focal length menu 406 to set the focal length of the lens of the camera device, and a shooting to set a time interval for performing interval shooting An interval menu 407, a shooting number menu 408 for setting the number of times to perform interval shooting, and returning to the display of the celestial sphere image 100 for the next setting without completing the interval image setting or changing the set parameters. And a back button 409 There.

  The slide button 401 is a slide-type button that determines whether or not to perform interval image setting. When the slide button 401 is turned on by a user's slide operation, the interval image setting becomes valid, and the interval image setting can be advanced thereafter. It becomes.

  The setting set selection menu 402 can be called by a user's tap operation by selecting and calling a sample preset setting, a user setting input in advance by the user, and the like. The input of parameters such as the altitude menu 405, the focal length menu 406, the shooting interval menu 407, and the shooting frequency menu 408 can be omitted, and the interval image can be set easily.

  In addition, as a sample setting, by preparing a shooting place with a wide field of view in order to take pictures of buildings such as landscapes and landmarks, the user can be presented with a place where they can easily take pictures. Can do. Further, it is preferable that the sample setting can be appropriately updated and added from the server device 30 via the network 20. Alternatively, the user settings may be stored in the server device 30 via a network and shared with other users via the network 20.

  The shooting date / time menu 403 allows the user to select the date / time for interval shooting when the user performs a tap operation.

  The shooting location menu 404 allows the user to select an observation location where interval shooting is performed when the user performs a tap operation. For example, as shown in FIG. 8, the map display menu is opened and an observation place is set on the map, an observation place is set by inputting a place name and an address, or information on the GPS sensor 55 of the terminal device 10 The observation location can be set by setting the observation location based on the above or by directly inputting the latitude and longitude of the observation location.

  The altitude menu 405 is used to set the altitude at the shooting location in units of meters (m) when the user performs a tap operation, and is used when displaying an interval image to be described later. Here, the altitude is the sum of the geographical altitude of the observation location plus the height of the building at the shooting location. In other words, simply inputting the geographical altitude will cause the celestial image of the celestial sphere image 100 at the time of shooting to deviate from the position of the landscape object that is the subject, making it impossible to accurately reproduce the interval image. is there.

  Here, although not described in FIG. 7, altitude data can be directly input numerically, but the altitude data is set based on the information of the GPS sensor 55 of the terminal device 10. However, since more accurate altitude data cannot be obtained with the accuracy of the GPS 55, the altitude data may be corrected based on atmospheric pressure fluctuations by the atmospheric pressure sensor 16 of the terminal device 10.

  The focal length menu 406 allows the user to set the focal length of the lens of the camera device in millimeters (mm) by a tap operation. Here, in the present embodiment, it is possible to set the focal length on the assumption that a full-size image sensor is used. For example, when a camera device including an APS-C size image sensor is used, a focal length obtained by converting the focal length of the lens to the equivalent of a full size image sensor may be input.

  Although not described in FIG. 7, a menu for setting the size of the image sensor may be prepared separately. In this case, the focal length menu 406 indicates the focal length described in the lens attached to the camera device. It is only necessary to input, and it is not necessary to perform conversion equivalent to a full-size image sensor.

  The shooting interval menu 407 can set a time interval for performing interval shooting in units of seconds (s), and is used when displaying an interval image to be described later. Specifically, it is set how far the moving celestial body is photographed within the camera angle of view.

  When shooting a celestial body with a large visual diameter, if the imaging interval is too short, the celestial images will overlap, so the minimum value may be limited according to the visual diameter of the target celestial body. Good. In addition, even in the case of a celestial body with a large visual diameter, it may not be preferable to limit the minimum value in the case of a celestial body that causes filling and loss in a short time, such as the moon during a lunar eclipse. It is preferable to be able to switch.

  The number of times of shooting 408 can set the number of times of interval shooting and is used when displaying an interval image to be described later. Specifically, it sets how many celestial bodies moving at the time interval set in the shooting interval setting menu 407 are displayed.

  The back button 409 is used to switch the display to the celestial sphere image 100 in order to complete the setting of each menu in the interval image setting screen 400 and make the next input for assisting interval shooting when the user performs a tap operation. .

[Shooting location setting menu screen]
Here, the shooting location setting menu in FIG. 8 will be briefly described. The shooting location setting menu screen 500 includes a time zone setting button 501, an observation location name display section 502, an observation location information setting button 503, a current location setting button 504, an observation location determination button 505, an observation location cancellation button 506, It consists of a map image 507, an observation location display pin 508 and the like.

  The time zone setting button 501 is used to change the time zone when the user taps the plus and minus buttons. For example, when the terminal device 10 is currently in Japan, a map in the zone of 9.0, that is, the world standard time + 9 hours is displayed, but when performing a simulation when performing interval shooting at an observation place other than Japan, This is used to set a time zone according to the observation location because problems such as inconsistent time information occur.

  The observation place name display unit 502 displays the observation place name that is currently set, and displays the place name input by the user's operation in the operation described later.

  The observation site information setting button 503 allows the user to add, select, delete, etc. the observation site information by performing a tap operation. Specifically, by operating the add button, information on the observation site display pin 508 can be added as observation site information. Although not shown in the figure, in the case of a newly added observation place, a menu for inputting the observation place name as a text is provided, and a specific place name, building name, and the like can be input by the user. As a result, the observation site name can be displayed on the observation site name display unit 502.

  The observation site information setting button 503 has an interface that allows the user to select an observation site from a preset sample or information previously added by the user by tapping the selection button. You can easily set the observation location.

  Furthermore, the observation location information setting button 503 is an observation that is no longer necessary by preparing an interface that allows the user to select an observation location from information previously added by the user by tapping the delete button. You can easily delete location information.

  The current location information setting button 504 can change the display area of the map image 507 based on the current position information of the terminal device 10 included in the terminal device 10 when the user performs a tap operation.

  When the user taps the decision button 505, the currently selected observation location can be validated and the shooting location setting menu screen 500 can be returned to the interval image setting screen 400.

  A cancel button 506 is tapped by the user to cancel the observation location selected on the current shooting location setting menu screen 500 and return to the interval image setting screen 400 from the shooting location setting menu screen 500. .

  A map image 507 is obtained by imaging the map information acquired by the terminal device 10 from the server device 30 or the like via the network 20 or stored in advance in the external memory 53 or the like, such as main roads, rivers, buildings, and the like. Contains information. Here, as a landscape object to be a subject, when performing interval shooting while a building such as a landmark is kept within the camera angle of view, the field of view of the shooting location must be open, and only simple map information can be used. If there is, it may be difficult to distinguish. In view of this, it is preferable that the map image 507 display information obtained by imaging a cityscape including a satellite photograph (a composite photograph of a ground photograph taken from the sky) in which a building such as a landmark is reflected.

  The observation location display pin 508 is a pin-shaped icon that represents the set shooting location on the map. If a plurality of observation locations are set within a range that can be displayed in the map image 507, a plurality of observation location display pins 508 may be displayed.

[Interval shooting angle setting]
The celestial sphere image 100 displayed after the user taps the return button 409 on the interval image setting screen 400 will be described with reference to FIG. In this embodiment, in order to facilitate understanding of the invention, the moving celestial body 116 that is a moving subject is a moon 160 with a lunar eclipse and a building image 112 that is a fixed subject as objects of interval shooting. Is assumed to be a high-rise observation tower.

  Note that the moving celestial body is not limited to the moon, and does not preclude targeting a plurality of celestial bodies. In addition, the building that is the fixed subject is not limited to the observation tower, and may include landscape objects such as landmark high-rise buildings, unique buildings, and non-buildings such as forests. It does not preclude targeting.

  As shown in FIG. 9, the celestial sphere image 100 displays the moon 160 and the orbit line 161 of the moon, and the parameter display image 104 displays parameters necessary for interval shooting. Further, compared with the celestial sphere image 100 described with reference to FIG. 4, unnecessary information for the description of the invention is omitted, but it is assumed that information equivalent to FIG. 4 is included. The same applies to the celestial sphere images 100 in FIG.

  The moon 160 is displayed so that its position is continuously changed along the orbit line 161 of the moon when the time information changes based on the operation input of the touch panel 13 of the user described later. Further, in the month 160, when the time information is changed based on the operation input of the touch panel 13 by the user, the state of eating, that is, the fullness is visually recognized while the position is continuously changed along the track line 161 during eating. Fullness is reflected as possible.

  Here, based on the time information, the display image of the month 160 may be calculated by reflecting the shadow state by calculating the food state in real time by the CPU 51 or the like, or may be generated by calculating the food state in advance. A plurality of stored image data may be prepared at predetermined time intervals and used. The former has an advantage that it is not necessary to secure a memory area for storing image data, and it is preferable to use the former in a portable information terminal device having a small memory area.

  Note that the apparent size of the moon 160 changes depending on the relative distance from the earth. Therefore, the display image of the moon 160 is displayed in the celestial sphere image 100 so that the size is calculated by the CPU 51 or the like and matches the actual apparent size. Note that if the size of a celestial body having a large visual diameter is calculated to be an actual size, the size of the celestial sphere may be difficult to see in the celestial sphere image 100 because the size of the celestial body is lost. In this case, a deformed size that does not reduce the size may be used.

  Here, the large celestial body magnification setting button 147 is a software button for changing the real size or the default size by a tap operation on the touch panel 13 by the user. It is preferable that the display of the large celestial body magnification setting button 147 is changed so that different graphics are displayed during real size display and during deformation size display. When the user determines that the month 160 is displayed in the default size by referring to the graphics of the large celestial body magnification setting button 147, the user may desire to display the real size in such a case. It becomes easy to determine the change of the display size. This can be said to be a function preferable for a user who wants to accurately confirm the finish of interval shooting using an interval image to be described later.

  Next, the trajectory line 161 is a line shown based on the trajectory calculation of the moon 160 and the like in order to make the trajectory of the moon 160 before and after the lunar eclipse easier to understand.

  The trajectory line 161 indicates a trajectory along which the moon 160 moves from a predetermined time before the start of the meal to a predetermined time after the end of the meal. The trajectory line corresponding to the meal is displayed with a thick line, and the front and back thereof are displayed with a line thinner than the thick line.

  Next, when the user slides up and down the celestial sphere image 100, the moon 160 and the building image 112 move up and down. The user can search for a suitable position for the camera angle of view so that the moon 160 and the building image 112 enter the camera angle-of-view auxiliary frame 106. FIG. 9 shows an adjustment in which the building image 112 is inserted into the camera angle assisting frame 106 by sliding upward with respect to FIG.

  Next, when the user slides the celestial sphere image 100 in the left-right direction, as shown in FIGS. 10 and 11, the moon 160 and the building image 112 move to the left and right. The user can search for a suitable position for the camera angle of view so that the moon 160 and the building image 112 enter the camera angle-of-view auxiliary frame 106.

  As described above, when the user slides the celestial sphere image 100 in the vertical and horizontal directions, the positional relationship between the moon 160, which is a moving celestial object, the building image 112, and the camera view angle auxiliary frame 106 is determined. In addition, while the positional relationship between the camera view angle auxiliary frame 106, the moon 160, and the building image 112 is changed by the slide operation, the shooting altitude and the shooting direction displayed in the parameter display image 104 are calculated in real time. The display is updated.

  The user can pinch in / pinch out the celestial sphere image 100 to enlarge or reduce the star map display range, but the relative relationship between the moon 160, the building image 112, and the camera view angle auxiliary frame 106 does not change. The explanation about the operation is omitted.

  Next, the time slider button 130 is a software button that moves when the user performs a sliding operation on the touch panel 13.

  The slide line 131 is a line indicating the moving range of the time slider button 130, and the time axis information corresponding to the trajectory line 161 is associated therewith.

  The time information 132 is a text display of time information corresponding to the position on the slide line 131 of the time slider button 130.

  The time information 132 is continuously changed by the sliding operation of the time slider button 130, and based on this time information, the orbit calculation including the position of the moon 160, the state of the eclipse, etc. is performed, and the celestial sphere image 100 is generated. It becomes the reference time.

  For example, in FIG. 12, the time slider button 130 is slid to the left by a minute amount, and the time information 132 is changed.

  The camera angle-of-view switch button 146 is a software button that changes the height and width of the camera angle of view by a user tap operation on the touch panel 13. When the camera angle-of-view switch button 146 is tapped, it can be said that the angle of view of the camera angle frame 106 is changed, that is, the camera angle of view rotated 90 degrees around the camera angle-of-view center target 111 is changed.

  In general, the angle of view of the camera is not the same length and width, but is a horizontally long rectangle according to the aspect ratio of the silver halide film or image sensor. The corner may be changed by 90 degrees. The camera angle-of-view switch button 146 changes the display of the camera angle-of-view auxiliary frame 106 so that the user can easily switch the direction in which the camera device is installed, assuming such a usage situation. Used for. FIG. 12 shows a state after the camera angle of view is changed to be a vertically long rectangle.

  A setting button 145 is a software button for calling up a menu for various settings of the program. The setting button 145 is a process in which the user performs a tap operation on the touch panel 13 to determine that these buttons have been pressed, and the setting menu or the help menu is replaced with the celestial sphere image 100 or superimposed on the display panel 12. Trigger. The setting menu and the help menu are omitted as they are applicable to each part of the present invention as appropriate.

[Interval image display processing]
The interval image display button 134 changes the month 160 in a state where the camera field angle auxiliary frame 106 is fixed based on the time information adjusted by the time slider 130, the set shooting interval (s) of the interval shooting, and the number of shootings. Is a button for starting the process of displaying multiple images. That is, as shown in FIG. 13, the month 160 that is multiplexed and displayed as the interval image 135 is displayed in the camera view angle auxiliary frame 106.

  In the interval image 135, the time of the time information 132 is set as the starting point, and the numerical value set in FIG. 7 is used, the interval is set to 420 seconds (s), the number of times of shooting is set to 30, and the interval shooting is performed. It is the simulation image which calculated.

  By confirming the interval image 135 by the user, it is possible to confirm a change in the position of the moon 160 and a change in the state of eating when the interval shooting is performed, which is useful for determining the camera angle of view of the camera device. be able to.

  Next, a case will be described in which the interval image mode button 103 is tapped to change the altitude while the interval image 135 is displayed. For example, when the observation site is a building, the appearance of a landscape object, which is a nearby subject, may vary greatly depending on the floor from which the image is taken.

  For example, when the altitude is changed to 100 m on the assumption that the image is taken from the roof of a high-rise building or near the observation room, the building image 112 falls downward within the angle of view as shown in FIG. However, the position of the horizon far from the observation site hardly changes, and the same applies to the moon 160.

[Display processing under the horizon]
In the present embodiment, in the celestial sphere image 100 and the interval image 135, the building image 112 is also displayed on a portion corresponding to the area below the horizon.

  In general, when describing landscapes based on advanced geographic information, for example, car navigation software and target buildings, as well as surrounding buildings and road information, the information below the horizon becomes extremely complicated. It is also difficult to confirm the horizon. In addition, with software that simulates a landscape such as a mountain based on advanced geographical information, the mountain information can be simulated with high accuracy, but the horizon cannot be seen, and the horizon is covered with a topographic image.

  In the present embodiment, as shown in FIG. 4, even if it is below the horizon, the celestial body can be displayed, and as shown in FIG. 14, the horizon upper portion 112 a and the horizon lower portion 112 b of the building image 112 are clearly distinguished. Display as you can.

  Thereby, even if the desired celestial body is buried under the horizon, it can be confirmed and is not hidden by other buildings or landscapes.

  As described above, based on the information displayed on the parameter display image 104, the user can use the shooting altitude and shooting direction of the camera device, the time for starting shooting displayed on the time information 132, and the interval image setting screen 400. Interval shooting can be performed with reference to the set shooting interval and shooting count. That is, it is possible to receive interval shooting support from the terminal device 10 with a simple operation.

  An image obtained by multiplexing interval shooting is usually difficult for the user to predict what the result will be unless it is completed, but by using the terminal device 10 of the present embodiment, an astronomical photograph is obtained. The interval image is easily simulated and displayed, and the user can easily predict the finish.

  The user can obtain various setting parameters for the best interval shooting by adjusting the camera device while checking the interval image displayed by the terminal device 10.

[Program processing]
As described above, the operation of the terminal device 10 has been described centering on the celestial sphere image 100 displayed on the display 12, but a specific processing program will be described with reference to FIGS. 15 to 18.

  The terminal device 10 has a function as a computer as described above, and the above function can be realized by the CPU 51 executing a program read from the internal memory 52 or the external memory 53.

[Interval image mode start processing]
Processing for starting various settings for performing interval shooting will be described.

  First, as shown in FIG. 15, the CPU 51 displays the celestial sphere image 100 on the display 12 based on the information read from the internal memory 52 or the external memory 53 or the information received from the server device 30 in step S101, and the user The celestial sphere image 100 is drawn while moving the star chart in a desired direction following the user's slide operation.

  Next, in step S <b> 102, the CPU 51 determines whether or not the interval image mode button 103 has been pressed by a user's tap operation on the touch panel 13. If the CPU 51 determines that the interval image mode button 103 has been pressed, the process proceeds to step S103. If the CPU 51 determines that the interval image mode button 103 has not been pressed, the process returns to step S101.

  Next, in step S103, the CPU 51 displays an interval image setting screen 400 on the display 12, as shown in FIG.

  Next, in step S <b> 104, the CPU 51 performs ON input of the slide button 401, selection input of the setting set selection menu 402, input of the shooting date / time to the shooting date / time menu 403, by the user's tap operation or slide operation on the touch panel 13. Input of shooting location in shooting location menu 404, input of elevation of observation location in altitude menu 405, input of focal length of lens in focal length menu 406, input of shooting interval in shooting interval menu 407, number of shooting in shooting count menu 408 The process which receives the input etc. of is performed.

  Next, in step S105, the CPU 51 determines whether or not the return button 409 has been pressed by a tap operation on the touch panel 13 by the user. If the CPU 51 determines that the return button 409 has been pressed, the process proceeds to step S106. If the CPU 51 determines that the return button 409 has not been pressed, the process returns to step S104.

  Next, in step S106, the CPU 51 displays the celestial sphere image 100 on the display 12 based on the items set on the interval image setting screen 400 as shown in FIG.

[Interval image display processing]
Next, processing for displaying an interval image will be described. This process is a process executed after the process described in FIG. 15 is completed.

  First, as shown in FIG. 16, the CPU 51 displays the celestial sphere image 100 on the display 12 based on the shooting date and time information set on the interval shooting setting screen in step S <b> 201.

  Next, in step S202, the CPU 51 moves the star map in a desired direction following the user's slide operation by the user's slide operation on the touch panel 13 with respect to the display area other than the various function buttons and the like. Describe. More specifically, an operation for aligning the camera field angle center target is performed so that a desired celestial body and a building image are placed in the camera field angle auxiliary frame 106 by a user operation.

  Next, in step S203, the CPU 52 moves the time slider button 130 following the user's slide operation by the user's slide operation on the touch panel 13, and adjusts the shooting start time. Specifically, an operation of adjusting the interval shooting start time and the center of the camera angle of view is performed so that a desired celestial body and a building image enter the camera angle-of-view auxiliary frame 106 by the user's operation.

  Next, when the interval image display button 134 is operated by the user's tap operation on the touch panel 13 in step S204, the CPU 51 advances the processing to step S205. On the other hand, when the CPU 51 determines that the interval image display button is not operated by a tap operation on the touch panel 13 by the user, the CPU 51 returns to the process of step S201.

  Next, in step S205, the CPU 51 displays an interval image 135 that multiplexly displays the movement of the celestial sphere image 100 within the angle of view with time change based on the start time of interval shooting determined in step S203. Although not described in FIG. 14, the display of the interval image 135 can be canceled when the interval image display button 134 is operated again.

[Camera angle of view change processing]
Next, processing for changing the camera angle of view will be described. This processing is executed after the processing described with reference to FIG. 15 is completed, but can be appropriately performed even during the processing described with reference to FIG.

  First, as shown in FIG. 17, the CPU 51 displays the celestial sphere image 100 on the display 12 based on the shooting date / time information set on the interval shooting setting screen in step S <b> 301.

  Next, in step S302, when the camera angle-of-view switch button 146 is operated by a tap operation on the touch panel 13 by the user, the CPU 51 advances the process to step S303. On the other hand, if the CPU 51 determines that the camera angle-of-view switch button 146 is not operated by a tap operation on the touch panel 13 by the user, the process returns to step S301.

  Next, in step S303, the CPU 51 switches and displays the vertical and horizontal directions of the camera angle assist frame 106. Specifically, when the camera view angle auxiliary frame 106 is normal, that is, when it is horizontally long, the camera device is changed to a vertically long frame line installed 90 degrees sideways, and the camera angle of view has already been obtained. When the vertical / horizontal switching button 146 is operated to form a vertically long frame line, the normal horizontal frame line is changed.

[Display processing under the horizon]
Next, processing for displaying the building image 112 below the horizon will be described. This processing can be appropriately performed even during the processing described with reference to FIGS.

  First, as shown in FIG. 18, the CPU 51 displays the celestial sphere image 100 on the display 12 based on the information of the shooting date and time set on the interval shooting setting screen in step 401.

  Next, in step S402, when the CPU 51 determines that the building image 112 in the celestial sphere image 100 is below the horizon by a user's slide operation on the touch panel 13, the process proceeds to step S403. On the other hand, if the CPU 51 does not determine that the building image 112 in the celestial sphere image 100 is below the horizon, the CPU 51 returns to the process of step S401.

  Next, in step S403, the CPU 51 superimposes and displays the translucent mask image on the lower horizon 112b of the building image 112. Thereafter, as long as there is no change in the positional relationship between the horizon 113 and the building image 112, the process of superimposing and displaying the translucent mask image is continued.

  The same processing may be applied to various celestial bodies displayed under the horizon 113. For simpler image processing, the lower part of the horizon 113 is covered with a translucent mask image. Also good. When such processing is performed, a translucent mask image is always superimposed on the lower part of the horizon 113, so that determination based on the positional relationship between the building image 112 and the horizon 113 can be omitted, and processing is accelerated. It becomes possible.

  As described above, the program processing is executed by the processing of the CPU 51 in the terminal device 10. In addition to the processing described in the flowcharts of FIGS. 15 to 18, each processing described above is programmed. Needless to say, you can do it.

  The terminal device 10 configured as described above is a combination of various hardware configurations and software configurations to set the interval shooting start time, shooting interval, and shooting count by the user, and to set parameters necessary for interval shooting as parameters. By displaying on the display image 104, it is possible to support interval shooting, and it is possible to display and visually provide an interval image that is a multiplexed photograph even before interval shooting.

  In addition, as for an object such as a landscape or a landmark as an object, an observation tower is taken as an example to illustrate one building image 112. However, the present invention is not limited to this, and a plurality of buildings are displayed. Needless to say.

[Interval shooting system]
Finally, the interval shooting system will be briefly described with reference to FIG.

  As shown in FIG. 19, the interval photographing system 200 includes a camera device 201, a tripod 202 that supports the camera device 201, and a free camera platform 203 that connects the camera device 201 and the rotating frame 202.

  Here, although the terminal device 10 described in the example of the present invention may be used as the camera device 201, a case where the dedicated camera device 201 is used will be described.

  The camera device 201 includes a lens 201a and a shutter controller 201b. The lens 201a may be detachable from the camera device 201 or may be integrated. The shutter controller 201b is a device that sends a signal to release the shutter at a predetermined interval to the camera device 201. By simply setting the shooting interval and the number of shooting times, the camera device 201 automatically performs interval shooting. It can be carried out. The shutter controller 201b may be built in the camera device 201.

  The tripod 202 only needs to have sufficient strength to support the camera device 201 and can be stably installed on the ground.

  In the interval shooting system 200 as described above, the orientation, altitude, shooting interval, and number of shootings that the camera device 201 is directed to are parameters required for interval shooting. The terminal device 10 described in the present embodiment can easily obtain these parameters, can assist the user in interval shooting, and can set an advanced level when the user sets the interval shooting system 200. Interval shooting can be easily enjoyed without the need for detailed knowledge.

  Note that the shooting interval and the number of shootings need not be strictly input. This is because the storage capacity of digital cameras in recent years has dramatically improved, so it is possible to record photographic images that are substantially more than the number of shots that can be considered with a film camera. This is because it is possible to compose a desired interval image by storing 1000 times of shooting data at a shooting interval shorter than planned, thinning out and selecting necessary cuts, and performing image processing. In other words, it can be said that it is necessary to input strictly when a silver salt film having a finite number of shootings of several tens is used.

  In the above, it demonstrated based on the example of this invention. The present invention is not limited to the above-described embodiments and the contents of each embodiment, and various modifications can be made within the scope of the gist of the present invention. Those skilled in the art will understand that the above-described embodiments are exemplifications, and that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are also within the scope of the present invention. .
