Description

  The present invention relates to a program and an electronic apparatus for displaying a plurality of display information according to various display position change rules.

  In recent years, browsing and editing of contents such as still images and moving images have been performed in various electronic devices. As the storage capacity of storage devices such as nonvolatile memories and hard disk drives provided in these electronic devices increases, the number of contents stored in the storage devices has become enormous. In addition to content already stored in the storage device, information on content such as videos, music, broadcast programs, books, etc. is acquired via a network such as the Internet, and the acquired information is displayed in a list. Yes.

  In such an environment, it is necessary to devise how to display information related to content so that the user can efficiently find desired content from a vast amount of information. For example, in Patent Document 1, thumbnail images of content are displayed side by side in a grid shape or an annular shape, and the display position of the thumbnail image is changed according to the user's scroll operation, so that the user can select desired content. ing.

JP 2009-205327 A

  However, in order to make the display position of the display information such as the thumbnail image of the content correspond to various change rules such as a lattice shape or an annular shape, each display is performed in an application that draws the display information as an image on the display of the electronic device. The process of calculating the coordinate value and size of information must be implemented for each change rule. Therefore, since the number of man-hours for developing a drawing application increases with an increase in the types of change rules, it is difficult to efficiently cope with many change rules.

  Therefore, an object of the present invention is to efficiently increase the types of display information display position change rules while suppressing an increase in the number of man-hours for developing a drawing application.

  A program according to one aspect of the present invention includes a change rule storage function for storing a plurality of types of change rules for the display position of each display information for a plurality of display information to be displayed on a display device on a computer; A reception function that accepts the number of display information and change rule specifying information for specifying one of a plurality of change rules from a drawing processing unit that controls drawing, the number of display information, and a change corresponding to the change rule specifying information Based on the rules, a position information output function for outputting position information indicating at least some display positions of the plurality of display information to the drawing processing unit is realized.

  Here, the computer is an electronic device that can realize various functions by executing a program, such as a mobile phone, a portable information terminal, or a personal computer. The display device is a device on which various visually recognizable information such as a still image, a moving image, and text is drawn as an image, such as a liquid crystal display. Note that the display device may be integrated with an electronic device such as a mobile phone or a personal digital assistant, or separate from the electronic device such as a desktop personal computer. It may be. The display information is information to be drawn on the display device, such as a still image, a moving image, and text. The drawing processing unit controls drawing on the display device, and is realized by a program different from the program according to the present invention. The display position is a position displayed in the display area of the display device, and is represented by a coordinate value, for example. The coordinates may be absolute coordinates or relative coordinates. The display position change rule is a rule for controlling the display position of display information. As a simple example, the display information is displayed in a list form arranged in a line in the vertical direction. It is a rule for scrolling information up and down.

  According to such a configuration, by specifying the number of display information and the change rule, the position information indicating the display position of at least a part of the plurality of display information is calculated according to the specified change rule. Is output. Therefore, the drawing processing unit does not need to calculate the display position of the display information by itself for various change rules, and simply draws the target display information at the presented display position. That is, it is possible to efficiently increase the types of display position change rules while suppressing an increase in the number of man-hours for developing a program for realizing the drawing processing unit.

  Further, the position information may include information indicating the size of an area where each display information is displayed on the display device.

  Note that the size of the display area is, for example, the vertical and horizontal sizes. The size may be an absolute value such as a pixel or a value indicating a relative size in the display area.

  According to such a configuration, when displaying a plurality of display information, the size of the display area of each display information can be changed.

  The position information output function updates position information indicating at least some of the display positions of the plurality of display information in accordance with user operation information for changing the display position of the display information displayed on the display device. May be output.

  Here, the user operation information is information that is output in response to the user's operation. For example, information indicating that the user has moved the finger upwards by touching the touch panel, or input by the user in the left direction. Information indicating that the key has been pressed.

  According to such a configuration, it is possible to change the display position of the display information according to the user operation information based on each change rule.

  Further, a program according to one aspect of the present invention provides the computer with user operation information unique to the input device that is output from the input device to change a display position of display information displayed on the display device. The conversion input conversion function may be further realized by user operation information in a predetermined format that can be processed regardless of the input device in the position information output function.

  Here, the input device is, for example, a touch panel, various input keys, a keyboard, or the like. For example, when the user operates the input device to move the display information displayed on the display device upward, the format of the user operation information output from the input device varies depending on the type of the input device and the manufacturer. there is a possibility. The user operation information in a predetermined format is operation information in a common format that does not depend on the input device.

  According to such a configuration, it is possible to correspond to various input devices having different output formats of user operation information.

  The position information output function may update and output position information indicating at least some display positions of the plurality of display information as time elapses.

  According to such a configuration, the display position of the display information can be automatically changed even when no user operation is performed.

  Further, at least one change rule among the plurality of change rules may be generated based on another change rule among the plurality of change rules.

  According to such a configuration, for example, when there is a change rule for displaying a list in the vertical direction, the change rule linearly changes the display position of the display information. By applying this function, it is possible to provide a change rule in which the list of display information changes sinusoidally.

  The plurality of display information includes a plurality of types of display information, and the reception function receives the number of display information for each type and change rule specifying information for specifying a change rule for each type from the drawing processing unit, The position information output function may output position information for each type of display information based on a change rule for each type corresponding to the received change rule designation information.

  Here, the type of display information indicates the contents and attributes of the display information. For example, in the case of displaying a grid-like electronic program guide centered on a broadcasting station and broadcasting time, information on the broadcasting station is displayed. , Broadcasting time information, and information on each program.

  According to such a configuration, when a plurality of types of display information are displayed at the same time, different change rules can be applied for each type of display information. For example, in the case of an electronic program guide, a list format that can be scrolled vertically for broadcast station display information, a list format that can be scrolled horizontally for broadcast time display information, and display information for each program By applying a grid format that can be scrolled in the vertical and horizontal directions, it is possible to display a grid-like electronic program guide centered on the broadcasting station and the broadcasting time.

  The reception function further receives the size of the display area of the display device, and the position information output function outputs position information based on the number of display information, the change rule corresponding to the change rule designation information, and the screen size. It is good to do.

  With such a configuration, the display information can be displayed at an appropriate position in accordance with the size of the display area of the display device.

  The position information output function may output position information for only display information that can be drawn in the display area of the display device, out of a plurality of display information, based on the screen size.

  With such a configuration, the data amount of position information output to the drawing processing unit is reduced, and the processing load can be reduced. For example, when the number of display information to be displayed is 100, the number of display information that can be simultaneously displayed in the display area of the display device in a certain display position change rule is 10. At this time, if the position information for only 10 display information that can be displayed is output to the drawing processing unit, the data amount is reduced to 1/10 compared to the case where the position information for all display information is output. It becomes possible to do.

  In addition, the reception function receives change rule designation information for designating a change rule different from the current change rule from the drawing processing unit, and the position information output function displays at least some of the display positions of the plurality of display information. The position information may be updated and output so as to continuously change from the display position in the change rule to the display position in the change rule corresponding to the newly accepted change rule designation information.

  An information processing apparatus according to one aspect of the present invention includes a drawing processing unit that controls drawing on a display device, and a display rule for changing a display position of each display information for a plurality of display information to be displayed on the display device. A change rule storage unit that stores a plurality of types, a reception unit that receives the number of display information and change rule designation information that specifies one of the plurality of change rules from the drawing processing unit, the number of display information, and a change rule And a position information output unit that outputs position information indicating at least some display positions of the plurality of display information to the drawing processing unit based on the change rule corresponding to the designation information.

  The information processing apparatus according to one aspect of the present invention further includes an input unit that inputs user operation information for changing a display position of display information displayed on the display device, and the position information output unit includes The position information indicating the display positions of at least some of the plurality of display information may be updated and output in accordance with user operation information input from the unit.

  In the information processing apparatus according to one aspect of the present invention, the position information output unit continuously updates the position information based on the change rule and outputs the updated position information to the drawing processing unit. When no time is input, the output of the position information to the drawing processing unit may be stopped.

  In the present invention, the term “unit” does not simply mean a physical means, but includes a case where the function of the unit is realized by software. Further, the functions of one unit or device may be realized by two or more physical means or devices, or the functions of two or more units or devices may be realized by one physical means or device.

  According to the present invention, it is possible to efficiently increase the types of display information display position change rules while suppressing an increase in the development man-hours of a drawing application.

== System configuration ==
FIG. 1 is a block diagram showing a functional configuration of an electronic device 10 according to an embodiment of the present invention. As shown in FIG. 1, the electronic device 10 includes a display unit 20, an input unit 22, a drawing processing unit 24, a display information storage unit 26, an input conversion unit 28, and a display position control unit 30. The display position control unit 30 includes a pattern storage unit 40, a reception unit 42, and a position information output unit 44.

  FIG. 2 shows an example of the hardware configuration of the electronic device 10. In the example illustrated in FIG. 2, the electronic device 10 includes a CPU (Central Processing Unit) 50, a memory 52, an HDD (Hard Disk Drive) 54, a display device 56, an input device 58, and a communication unit 60. .

  The display unit 20 displays various information as an image, and includes a display device 56 such as a liquid crystal display or an organic EL display, for example. In the present embodiment, the display device 56 is incorporated in the electronic device 10, but the display device 56 is provided separately from the electronic device 10 like a liquid crystal display connected to a desktop personal computer. It may be.

  The input unit 22 enables user operation information to be input, and includes, for example, an input device 58 such as a mobile phone input key, a touch panel, a touch pad, a keyboard, a mouse, and a voice recognition device. In the case where a touch panel is used as the input device 58, the input device 58 and the display device 56 may be integrally configured. The input device 58 may be configured separately from the electronic device 10.

  The drawing processing unit 24 is an application that draws information such as moving images, still images, and texts, which are various display information to be displayed on the display unit 20, on the display unit 20 as images that can be viewed by the user. In addition to the information already stored in the display information storage unit 26, the drawing processing unit 24 acquires various information from the Internet, for example, via the communication unit 60, and stores it in the display information storage unit 26 as display information. can do. The drawing processing unit 24 is realized by the CPU 50 executing a program stored in the memory 52.

  The display information storage unit 26 stores various display information to be displayed on the display unit 20 and includes a memory 52 and an HDD 54. The display information storage unit 26 may be configured separately from the electronic device 10 and connected to the electronic device 10 via a connection interface such as a memory card slot or a USB terminal.

  The input conversion unit 28 converts user operation information output from the input unit 22 into a predetermined format that does not depend on the specifications of the input unit 22 and outputs the converted information to the display position control unit 30. For example, if the information displayed on the display unit 20 is to be moved upward, the down arrow key is pressed if it is an input key of a mobile phone, and if it is a touch panel, it is flicked upward (with a finger on the touch panel). May be traced lightly). Therefore, regardless of which of the user operation information corresponding to the pressing of the down arrow key and the user operation information corresponding to the upward flick operation is output from the input unit 22, the input conversion unit 28 displays the display information in the upward direction. The user operation information in a predetermined format indicating that the user operation for moving the image is performed is output to the display position control unit 30. Not only the type of the input unit 22 but also the manufacturer of the input unit 22 may have different user operation information formats, and the input conversion unit 28 absorbs such a difference. In order to realize such a function, for example, the input conversion unit 28 holds a table indicating a correspondence relationship between user operation information output from various input units 22 and corresponding user operation information in a predetermined format. It may be configured to. The input conversion unit 28 is realized by the CPU 50 executing a program stored in the memory 52.

  The display position control unit 30 outputs position information for controlling the display position of various display information displayed on the display unit 20. The position information includes information on the coordinates and size of the display area where each display information is displayed on the display unit 20. In the present embodiment, the display area of each display information is referred to as a “frame”. The display position control unit 30 is not used only for the specific drawing processing unit 24 but is provided as a library that can be used in common by the drawing processing units of various electronic devices. The display position control unit 30 is realized by the CPU 50 executing a program stored in the memory 52.

  The pattern storage unit 40 stores a plurality of types of information indicating the change rule of the display position of the display information. Here, the display position change rule indicates a rule for controlling the display position of each display information frame, and is referred to as a pattern in the present embodiment. Specifically, the information indicating the change rule includes, for example, information indicating the arrangement position of each frame in the display area (display space) of the display unit, or when changing the display position of each frame according to a user operation. Information indicating a function, information indicating a function when the display position of each frame is changed over time, information for controlling the display positions of the plurality of frames in the display area of the display unit, and the like are included.

  FIG. 3 shows an example of a pattern. FIG. 3A shows a pattern called “list”, for example, and a plurality of frames 70 a to 70 e are arranged in a vertical line. In this list pattern, for example, the display position of each frame changes in the vertical direction according to a user operation or the passage of time. FIG. 3B shows a pattern called “circle”, for example, and a plurality of frames are arranged in an annular shape. In this circle pattern, for example, the display position of each frame changes so as to rotate clockwise or counterclockwise according to the user operation or the passage of time. FIG. 3C shows a pattern called “grid”, for example, in which a plurality of frames are arranged in a lattice pattern. In this grid pattern, for example, the display position of each frame changes in the vertical and horizontal directions according to user operations and the passage of time. Note that the pattern storage unit 40 stores the identifiers of these patterns and the rules for changing the display position of each frame in each pattern in association with each other. The pattern storage unit 40 may be stored in the memory 52 as an executable code for calculating position information according to a change rule for each pattern, or the memory 52 as data referred to by the position information output unit 44. May be stored.

  The receiving unit 42 receives change rule specifying information for specifying the number of display information to be displayed on the display unit 20, the size of the entire display area of the display unit 20, and a pattern for display.

  The position information output unit 44 outputs position information indicating the display position of each display information frame based on the pattern information specified by the change rule specifying information stored in the pattern storage unit 40. Here, the change rule designation information includes, for example, a pattern identifier. The position information output unit 44 updates and outputs the position information based on the user operation information in a predetermined format output from the input conversion unit 28. The position information output unit 44 is realized by the CPU 50 executing a program stored in the memory 52.

  Note that the pattern storage unit 40 and the position information output unit 44 may not be clearly separated, and may be integrally configured by a program that outputs position information according to a change rule for each pattern.

== Description of operation ==
Hereinafter, display position control processing by the display position control unit 30 will be described.

  FIG. 4 shows an overview of the display position control process. First, the drawing processing unit 24 displays information specifying the number of display information (the number of frames) to be displayed on the display unit 20, the size of the entire display area of the display unit 20, and the pattern, and the display position control unit 30. (S401). Here, the number of display information is not the number of display information displayed simultaneously on the display unit 20 but the total number of display information that may be displayed on the display unit 20. For example, if a thumbnail image of a still image stored in a certain folder in the display information storage unit 26 becomes display information, the number of display information is the total number of still images stored in that folder. It is.

  The display position control unit 30 continuously updates the position information of each frame based on the change rule in the designated pattern, the user operation information, and the time information. The update of the position information based on the time information is to change the display position of each frame as time passes regardless of whether or not a user operation is performed. For example, in the case of the list pattern shown in FIG. 3A, the frame can be scrolled upward little by little even when there is no user operation.

  The drawing processing unit 24 repeatedly executes an inquiry about the position information of each frame in a short cycle with respect to the display position control unit 30 (S402). In response to this inquiry, the display position control unit 30 outputs the position information of each frame to the drawing processing unit 24 (S403). The position information includes information on coordinates for displaying the frame and the size of the frame. For example, if the shape of the frame is a square, the position information about each frame can be expressed as (frame ID, X coordinate, Y coordinate, vertical size, horizontal size). Here, the frame ID is information for identifying each frame. For example, if the total number of frames is 100, numbers from 1 to 100 may be assigned according to the display order of the frames. Further, the coordinate value may be the coordinates of a point serving as a reference for the position for displaying the frame, and may be, for example, the coordinates of the center point or end point of the frame. In addition, the size of the frame may be specified by a pixel value or the like for the vertical and horizontal sizes, or by a relative value with respect to the size of the display unit 20. If the frame is a square, the display position of the frame may be specified by specifying the coordinates of two diagonal points among the four end points.

  In addition, the display position control unit 30 may output only position information regarding a frame that can be displayed on the display unit 20 among all the frames specified by the drawing processing unit 24. For example, when an inquiry is received for a frame with a frame ID of 1 to 100, if the frame with a frame ID of 10 to 15 is displayable in the display area of the display unit 20 at that time, Instead of outputting position information for all frames, only position information for frames with frame IDs 10 to 15 may be output.

  Then, the drawing processing unit 24 determines the coordinates and size of each frame based on the received position information, and draws the display unit 20 so that the corresponding display information is displayed as an image in each frame. Do. For example, when the display information is a thumbnail image of a still image or a moving image, the drawing processing unit 24 may display the thumbnail image in the frame by enlarging or reducing the thumbnail image according to the size of the frame. In addition, for example, when a part of the frame 70a, 70e in FIG. 3A is outside the display area of the display unit 20, the drawing processing unit 24 sets the coordinates of the frames 70a, 70e and The drawing process may be performed so that part of the display information is displayed according to the size.

  FIG. 5 is a flowchart illustrating a detailed example of the display position control process. First, the number of frames, the screen size, and the pattern are specified from the drawing processing unit 24 (S501). In the display position control unit 30, the reception unit 42 receives information specifying the number of frames, the screen size, and the pattern (S502), and the position information output unit 44 changes the target pattern stored in the pattern storage unit 40. According to the rule, the position information of each frame is calculated (S503).

  The drawing processing unit 24 monitors the presence / absence of a user operation via the input unit 22 (S504). If there is a user operation (S504: Y), the user operation information is output to the position information via the input conversion unit 28. The data is output to the unit 44 (S505). When receiving the user operation information (S506: Y), the position information output unit 44 updates the position information of each frame based on the user operation information (S507). For example, if the user operation information indicates an instruction to change the display position of the display information upward, the position information is updated so that the display position of each frame changes upward according to the change rule in the specified pattern. Is done. Even if the user operation is the same, the change in the display position according to the user operation differs depending on the pattern.

  Further, when the position information output unit 44 is a pattern (time interlocking pattern) in which the designated pattern is updated in conjunction with the passage of time regardless of the presence / absence of a user operation (S506: Y / N). (S508: Y), the position information of each frame is updated in conjunction with the passage of time (S509).

  Then, the drawing processing unit 24 inquires of the position information output unit 44 about the position information of each frame (S510). In response to this inquiry, the position information output unit 44 outputs the position information of each frame to the drawing processing unit 24 (S511). Then, the drawing processing unit 24 draws display information for each frame based on the received position information of each frame (S512). The position information output unit 44 may output the position information of each frame to the drawing processing unit 24 without receiving an inquiry from the drawing processing unit 24.

  As described above, the position information update process described above is performed in response to a user operation or the passage of time, and the drawing processing unit 24 sends a position information inquiry to the position information output unit 44 in a short cycle. By being repeatedly performed, a plurality of display information is displayed on the display unit 20 while their display positions change according to the user operation or the passage of time. Note that the short cycle is preferably a cycle in which the amount of change in the position information of each frame is sufficiently small so that the display information displayed in each frame moves visually smoothly.

  The position information output unit 44 outputs the position information of each frame when the designated pattern is not a time-linked pattern (S508: N) and there is no user operation for a predetermined time (S513: Y). (S511) is stopped until a new user operation is performed. Also, in the drawing processing unit 24, when it is not a time-linked pattern (S514: N) and there is no user operation for a predetermined time (S515: Y), a process for inquiring the position information of each frame (S510) is newly added. Until user operation is performed. That is, in the case of not being a time interlocking pattern, when there is no user operation for a predetermined time, position information inquiry and output repetition processing between the drawing processing unit 24 and the position information output unit 44 are stopped. As a result, the processing load on the electronic device 10 can be reduced.

  In the example of FIG. 5, the drawing processing unit 24 and the position information output unit 44 each determine whether or not an operation has been performed for a predetermined time, but either one determines and notifies the other. It is good to do. For example, when the drawing processing unit 24 detects that a user operation has not been performed for a predetermined time (S515: Y), the processing of the position information output unit 44 is stopped and a new user operation is performed. (S504: Y), the processing of the position information output unit 44 may be restarted.

  In the example of FIG. 5, the display information pattern can be changed midway. Specifically, the drawing processing unit 24 determines whether there is a pattern change (S516). If there is a pattern change (S516: Y), information about the changed pattern is output to the position information output unit 44. (S517). Then, in the display position control unit 30, the reception unit 42 receives information about the pattern after the change (S518), and the position information output unit 42 uses each of the pattern before the change and the pattern after the change. The frame position information is updated (S519).

  For example, when the pattern before the change is the grid format pattern shown in FIG. 6 and the pattern after the change is the list format pattern shown in FIG. 7, the position information output unit 44 first sets each pattern in the changed pattern. The display position of the frame is calculated. For example, in the grid pattern shown in FIG. 6, if the frame indicated by No. 6 is in focus, the position information output unit 44 uses the No. 6 pattern in the list format pattern shown in FIG. The display position of each frame is calculated so that the frame is the center of the display area of the display unit 20. Then, the position information output unit 44 changes each frame so that the display position of each frame in the grid pattern shown in FIG. 6 continuously changes to the display position of each frame in the list pattern shown in FIG. Update location information.

  For example, the position information may be updated so as to move on a straight line from the display position in the pattern before the change toward the display position in the pattern after the change. FIG. 8 shows an example of this, and frames Nos. 4, 6, and 8 move linearly from the display position (solid line) in the pattern before change to the display position (dashed line) in the pattern after change. It is shown. In addition, when the display position is changed, the moving speed of the frame may be changed according to time or distance. For example, the pattern change may appear smoother by updating the position information so that the frame moves slowly at the beginning and end.

  Further, the change in the display position of the frame at the time of pattern change is not limited to movement on a straight line, and any other form can be considered. For example, when the pattern before the change is the grid format pattern shown in FIG. 9 and the pattern after the change is the circle format pattern shown in FIG. 10, each frame after the change is displayed from the display position of each frame before the change. Instead of changing linearly to the display position, the display position of each frame may be changed non-linearly through a random state as shown in FIG. 11, for example. Such a change rule can be realized by using, for example, a non-linear function or a random number.

== Pattern application example ==
Next, application examples of patterns will be described. Although an example of a basic pattern is shown in FIG. 3, various other patterns can be stored in the pattern storage unit 40. Also, another pattern can be provided based on a certain pattern. For example, the list pattern change rule of FIG. 3A changes the display position of a plurality of frames along a straight line in the vertical direction. By changing this straight line to a sine wave, the change of FIG. It is also possible to provide a “sine curve” pattern shown in a). Also, as shown in FIG. 12B, a pattern in which the display positions of all the plurality of frames in the circle pattern of FIG. 3B are shifted to the right side can be provided as an “arch” pattern. Here, assuming that the frame in the circle pattern in FIG. 3B is captured by a certain camera and displayed in the display area of the display unit 20, the display unit 20 is shifted by shifting the position of the camera to the left side. The display position of the frame displayed in the display area is as shown in FIG. That is, a plurality of patterns can be provided by changing information for controlling the display positions (camera positions) of the entire plurality of frames in the display area of the display unit 20.

  Further, as shown in FIG. 13, it is possible to provide a pattern that artificially expresses three dimensions by changing the size of the frame little by little. In the pattern shown in FIG. 13, the second to fifth frames partially overlap other frames. In such a case, the drawing processing unit 24 executes the drawing process so that the display information is displayed in an area that does not overlap with other frames. In addition, when the display positions of a plurality of frames overlap, the display position control unit 30 may output information indicating the front-rear relationship in the depth direction of these frames in the position information.

  Further, as shown in FIG. 14, by changing the boundary line of each frame to an angle different from the vertical and horizontal directions of the display unit 20, it is possible to provide a pattern that artificially represents an inclination of an arbitrary angle. it can. In this case, the display position control unit 30 can specify the coordinates and size of each frame by, for example, the coordinate values of the four points of each frame. Alternatively, the display position control unit 30 may output, for example, information indicating the inclination of each frame from the vertical or horizontal direction in the position information.

  Further, as shown in FIG. 15, patterns corresponding to a plurality of types of display information can be provided. For example, the pattern shown in FIG. 15 corresponds to an electronic program guide that includes display information about broadcast stations, display information about broadcast times, and display information about program information. Specifically, the pattern shown in FIG. 15 includes a vertical list format pattern 80 in which display information about a broadcasting station is displayed, a horizontal list format pattern 82 in which display information about a broadcast time is displayed, and a program. It is configured by a combination of grid format patterns 84 on which display information related to information is displayed. In this case, the drawing processing unit 24 notifies the display position control unit 30 of the number of frames for each type of display information. Then, the display position control unit 30 updates the position information according to the corresponding pattern change rule for each type of display information so that the display positions of these three types of display information change in conjunction with each other, and the drawing processing unit 24. Specifically, for example, in response to a user operation to move display information related to program information to the left side, the display position control unit 30 moves display information related to broadcast time to the left side in conjunction with display information related to program information. In addition, the position information related to the program information and the position information related to the broadcast time are updated and output. Further, for example, in response to a user operation for moving the display information related to the program information upward, the display position control unit 30 moves the display information related to the broadcasting station in association with the display information related to the program information so as to move upward. The position information related to the information and the position information related to the broadcasting station are updated and output.

  The embodiment of the present invention has been described above. According to the present embodiment, when the number of frames and the pattern are designated from the drawing processing unit 24, the display position control unit 30 obtains position information indicating the display position of each frame according to the change rule in the designated pattern. Calculated and output. Therefore, when it is desired to realize various display patterns, the drawing processing unit 24 does not need to calculate the display position of the display information in each pattern by itself, and simply displays the display position notified from the display position control unit 30. In addition, it is only necessary to draw the display information. For this reason, it is possible to efficiently cope with a plurality of patterns while suppressing an increase in the development man-hours of the program for realizing the drawing processing unit 24.

  Further, according to the present embodiment, the position information output from the display position control unit 30 includes information indicating the size of each frame. As a result, the size of each frame can be dynamically changed.

  Moreover, according to this embodiment, in each pattern, the display position of each frame can be changed according to user operation information. Even in the same user operation, the effect according to the operation is determined according to the pattern change rule. For example, when the user presses the down arrow key, the position information is updated so that the display information moves upward in one pattern, and the size of the display information is changed in another pattern. Location information may be updated.

  Further, according to the present embodiment, user operation information output from the input unit 22 can be converted into user operation information in a predetermined format and output. Thereby, it can respond to the various input parts from which the format of user operation information differs. That is, the drawing processing function can be ported to various electronic devices having different specifications of the input unit.

  Note that this embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention can be changed / improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

  For example, in the present embodiment, a pattern in which the shape of the frame is a square is illustrated, but the shape of the frame is not limited to a square, and may be an arbitrary shape. For example, a circular or oval frame may be used. In this case, the position information may include the diameter of the circle, the length of the major and minor axes of the ellipse, the angle of inclination of the major axis of the ellipse with respect to the horizontal direction, and the like. Further, the position information may include information indicating the shape of the frame.

  For example, in the present embodiment, the drawing processing unit 24 outputs information related to the size of the entire display area of the display unit 20 to the display position control unit 30, but the information related to the size of the display unit 20 is It is good also as not outputting. In this case, for example, the display position control unit 30 outputs position information indicating a relative position in the display area of the display unit 20, so that the coordinates and size of each frame are irrespective of the size of the display area of the display unit 20. Can be appropriately controlled.

  Further, for example, in the present embodiment, a two-dimensional coordinate value is output as position information, but a three-dimensional coordinate value may be output.
