[Information processing device]
In FIG. 1, the information processing apparatus 100 stores a CPU 101 that controls the whole, a boot ROM 104 that stores a program for starting the information processing apparatus 100, an image generation program executed by the CPU 101, and other programs and data. The system memory 102 is applied to a game information processing device such as a computer that executes a general information processing program, a personal computer that can execute a program such as a golf game, a game device, and a communication device such as a mobile phone. ing.

  The image generation program and data executed by the CPU 101 include a program and data for generating and controlling an image to be displayed in addition to a program and data for controlling a game.

  In order to generate an image to be displayed, polygon data (vertex data) and NURBS data (curved surface and control point data) having 3D local coordinate data constituting an object to be displayed are stored in the system memory. This is arranged in the world coordinate system of the three-dimensional virtual space by a CPU or a geometry processor (not shown) to convert the local coordinates into the world coordinate system.

  Furthermore, a viewpoint coordinate generated as a player's operation or a game progresses is set in the world coordinate system, and an object in a visual field range viewed from the viewpoint in a predetermined viewing direction and angle of view is set as a viewpoint coordinate. Conversion to the viewpoint coordinate system with the origin is performed, and the converted coordinates of the object are transmitted to the rendering processor 107.

  The rendering processor 107 first applies interpolation processing such as light source processing or the texture data stored in the graphic memory 108 to the object to detail the surface of the object with respect to the received object coordinates. Further, the rendering processor 107 projects an object (polygon) from a three-dimensional solid object onto a two-dimensional plane (screen) for display on the display means 112 and converts it into two-dimensional coordinate data (screen coordinate system). A two-dimensional image is generated so as to display preferentially from a polygon having a shallow coordinate depth, that is, a polygon close to the viewpoint coordinate, and this is output to the display means 112 such as a CRT or a liquid crystal display device.

  That is, the CPU 101 and the rendering processor 107 are controlled by the image generation program and function as the image generation unit 117.

  The information processing apparatus 100 is provided with input means such as an operation input switch 105, a golf club controller 115, and a touch panel 116, and the golf club 1092 (FIGS. 2 and 3) is operated by the golf club controller 115.

  The touch panel 116 is provided along the display surface of the display unit 112. The touch panel 116 makes a variety of inputs possible by changing the contact information of the indicator by bringing a pointer such as a finger into contact with the touch panel 116 and changing the pressure that the indicator contacts or by appropriately moving the contact position. Yes. That is, the touch panel 116 functions as a contact detection unit. Further, the contact detection means is not limited to detecting contact of an indicator such as a touch panel, but the display surface of the display means is irradiated with light (infrared rays) by sensors such as a plurality of infrared sensors provided along the edge of the display means. ) And ultrasound, and the indicator coordinates (position) on the display surface are specified by identifying the light (infrared rays) or the sensor corresponding to the ultrasound that is blocked by the indicator regardless of whether the indicator touches the display means. ), And the display surface scanning lines detected by the indicator such as a light gun, and the display surface scanning coordinates are detected, and light (infrared rays) and ultrasonic waves emitted from the indicator are applied to the corners of the display surface. Some sensors detect the detected coordinates (position) on the display surface based on the amount of detected light and ultrasonic waves or the detected timing (time difference). It is referred to as a detection means.

  The information processing apparatus 100 is provided with a sound processor 109 that generates sound and a sound memory 110 that stores data of the generated sound. The sound processor 109 stores sound based on the data stored in the sound memory 110. A digital signal is generated, and sound is output through a speaker 113 and headphones (not shown).

  The information processing apparatus 100 is provided with a program data storage device and a storage medium 103, and game programs and data stored in the storage medium 103 are read into the system memory 102, the graphic memory 108, and the sound memory 110.

  The data stored in the storage medium 103 includes information regarding the game.

  These storage media include optically readable media such as CD-ROM and DVD-ROM, and electrically readable media such as mask ROM and flash memory.

  The information processing apparatus 100 includes a communication interface 111 and a modem 114, and is connected to the network IN via the LAN and the modem 114.

  The above components of the information processing apparatus 100 are connected to a bus, and the bus arbiter 106 controls input / output between the components of the program and data.

  2 and 3, the image displayed on the display unit 112 in relation to the golf game includes, for example, a golf course scene BG, an object such as a player 1000, a ball 1094, a cup 1090, and a mode. A switching button 1040, a cup position instruction object 1050, and a hit point setting icon 1060 are displayed. Further, a viewpoint left movement button 1010, a viewpoint right movement button 1020, a viewpoint switching button 1030, and the like are displayed as visual field range movement instruction objects. The cup position instruction object 1050 also has a function as a visual field range return instruction object. At this time, the viewpoint position in the three-dimensional virtual space is arranged in front of the player with respect to the depth direction of the three-dimensional virtual space on the vertical plane through which the straight line connecting the player or the ball and the cup passes. By doing so, on the screen immediately after the start of the game, the player can obtain an image in which the player is positioned in front of the cup as shown in FIG.

  Further, in the same image, each hole specification 1070, player name 1072, total score 1074, total point 1076, club display 1078, play time display 1080, shot display 1082, player energy display 1084, and explanation display 1086 do not overlap each other. Are displayed in front of the BG or the player 1000, that is, in front of the screen.

  The hit point setting icon 1060 sets the position of the ball 1094 to be hit by the club 1092, that is, the position where the ball 1094 is shifted from the center on the lower side, the right side, the left side, and the upper side.

  The cup position indicating object 1050 is displayed on the two-dimensional plane on a straight line connecting the ball 1094 and the cup 1090 on the two-dimensional plane of the display surface when the cup 1090 is displayed in front of the ball 1094. Even in the situation where the cup 1090 is not visible, the direction of the cup 1090 is shown.

  For example, as shown in FIG. 4, in a situation where the player 1000 hits a ball 1094 toward the cup 1090, when the player cannot see from the viewpoint EY (represented by the camera CM) due to the undulation of the ground BG, The cup position indicating object 1050 is arranged at a position sufficiently close to the viewpoint EY from the height of the approximate viewpoint EY (indicated by a broken line object 1050P).

  Thus, for example, even when an obstacle such as a tree 4000 higher than the height of the viewpoint EY exists on the ground BG, the cup position indicating object 1050 is visible.

  If the cup is not located directly in front of the ball, it is displayed on a straight line connecting the viewpoint and the cup. Further, it may be controlled to be displayed on a straight line connecting the viewpoint and the cup regardless of whether the cup 1090 is present in front of the ball 1094.

  Further, the cup position indicating object 1050 displays the X coordinate in common with the display position of the cup 1090 on the two-dimensional plane, and displays the Y coordinate at a position moved, for example, upward by a predetermined position, thereby changing the viewing direction. In this case, the cup position indicating object 1050 may be displayed without changing the display condition. That is, the cup position indicating object is not arranged in the three-dimensional virtual space, the position of the cup in the screen coordinate system is stored in advance, and after the coordinate conversion to the screen coordinates is completed, the cup position indicating object is directed upward. You may make it arrange | position in the position which shifted | deviated predetermined position. Furthermore, if a two-dimensional image of the object is generated so that the display of the cup position indicating object is closest to the front, and then synthesized on the image, an obstacle such as a tree 4000 higher than the height of the viewpoint EY. Even when an object is present, the cup position indicating object 1050 is visible.

  In the specification 1070 of each hole, the number of holes and the distance are displayed. For example, “NORMAL” is displayed on the shot display 1082, and the energy held by the player 1000 is indicated by the number of star marks in the player energy display 1084. Is displayed. This energy display is reduced by the player's play failure and the number of hits of the ball, and when the energy becomes zero, the game is over. The explanation display 1086 shows an operation method on the screen.

  FIG. 2 and FIG. 3 show the situation of putting a pat, and undulation is important. Therefore, the coordinate display object 2000 and the tilt display object 3000 are displayed on the screen in order to display the tilt of the ground.

  The coordinate display object 2000 has a cross shape, and is arranged between the ball 1094 and the cup 1090 in correspondence with the arrangement at equal intervals in the horizontal plane. In the virtual three-dimensional space, the X axis is set in the horizontal direction of the screen, the Y axis is set in the vertical direction, and the Z axis is set in the depth direction. The coordinate display object 2000 is in the height direction of the surface of an object such as the ground on the X and Z coordinate planes. Are arranged in a grid pattern at the Y coordinate position.

  The tilt display object 3000 descends between the pair of coordinate display objects 2000 at a speed set based on the tilt of the pair of coordinate display objects 2000 adjacent in the X-axis direction or the Z-axis direction, that is, the difference between the Y coordinates. Move in the direction.

[Image generation program: Non-returnable view range processing]

  In the image of FIG. 2, the viewpoint is set in the direction in which the player 1000 hits the ball 1094 toward the back of the screen. By pressing the viewpoint switching button 1030, as shown in FIG. You can change the viewpoint to face.

  The visual field range left movement button 1010 includes a rapid movement button 1012 and a slow movement button 1014. When the sudden move button 1012 is pressed, the field of view BG moves to the right by moving the field of view to the left at a relatively high speed, and the scenes hidden on the left are sequentially displayed. When the slow movement button 1014 is pressed, the visual field range moves to the left at a relatively slow speed.

  The visual field range right movement button 1020 includes a rapid movement button 1022 and a slow movement button 1024. When the quick move button 1022 is pressed, the field of view BG moves to the right at a relatively fast speed, so that the scene BG moves to the left and the scenes hidden on the right are sequentially displayed. When the slow movement button 1024 is pressed, the visual field range moves to the right at a relatively slow speed.

  After the visual field range is moved by the visual field range left move button 1010 or the visual field range right move button 1020, when the cup position instruction object (visual field range return instruction object) 1050 is pressed, the viewing direction returns to the state before the movement.

  Note that the visual field range is moved when the viewing direction rotates around the viewpoint, the viewpoint position moves, or both move.

  As described above, since the slow movement button 1014 and the slow movement button 1024 are arranged in proximity to the sudden movement button 1012 and the sudden movement button 1022, respectively, the visual field range can be moved slowly and rapidly.

  When moving the visual field range, the cup position indicating object 1050 is also moved to the right or left together with the scene BG. However, when reaching the right end or the left end, the cup position indicating object 1050 is controlled so as not to move any more and stay in the screen. As a result, the visual field range can always be returned. This control differs in control method depending on whether the cup position indicating object is arranged in the three-dimensional virtual space, or is set on screen coordinates or a two-dimensional image.

  When it is arranged in the 3D virtual space, it is determined whether it has moved to the right end or the left end according to the amount of movement of the visual field range with respect to the reference visual field range. , It is determined whether the cup position indicating object has moved to the right end or the left end according to the amount of movement of the cup position indicating object with respect to the reference arrangement position, and by these determinations, the display position of the cup position indicating object is fixed regardless of the movement of the visual field range. To do.

  The visual field range left moving button 1010 is arranged on the left side from the center of the display screen, and the visual field range right moving button 1020 is arranged on the right side from the center of the display screen. In general, an object important for the progress of the game, such as the player 1000, is arranged at the center of the screen, and a visual field range left moving button 1010 and a visual field range right moving button 1020 (the “visual field range moving instruction object” is a general term for these). By arranging them close to the left and right, the display of important objects is not hindered.

  Also, as shown in FIG. 3B, the visual field range movement instruction object arranges the left movement button 1010 and the right movement button 1020 side by side with respect to the center of the display screen (for example, right-justified). Anyway.

  That is, the visual field range movement instructing object can be prevented from obstructing object display by being distributed to the left or right while avoiding the central portion, or arranged to be moved to the left or right.

  Further, similarly to the visual field range return instruction object, the visual field range movement instruction object is displayed sufficiently close to the viewpoint in the three-dimensional virtual space so that the display is not obstructed by the obstacle. Alternatively, as in the case of the cup position indicating object, the object may be arranged at a fixed position in the screen coordinate system after the coordinate conversion to the screen coordinates is completed without being arranged in the three-dimensional virtual space. Further, at this time, when a two-dimensional image of the object is generated so that the visual field range movement instruction object is displayed closest to the front, it is synthesized on the image, as in FIG. It is also visible when there are obstacles such as tall trees 4000.

  The visual field range movement instruction object and the visual field range return instruction object are set by the CPU 101 and the rendering processor 107. Therefore, the CPU 101 and the rendering processor 107 function as instruction object setting means such as the visual field range movement instruction object and the visual field range return instruction object. To do.

  In FIG. 15, the principle of the viewing direction movement of FIGS. 2 and 3 will be described.

  If the viewpoint EY is represented by the camera and the line of sight P is represented by the optical axis of the camera, when the camera CM1 is rotated to the state of CM2 and CM3, the screens that project the three-dimensional virtual space WC such as a golf course are displayed from SC1 to SC2, SC3. It changes as follows. The camera CM2 rotates the optical axis (line of sight P) of the camera CM1 to the lower right, and the camera CM3 rotates the optical axis (line of sight P) of the camera CM1 to the upper left.

  Instead of the above-described viewing direction movement (line of sight rotation) processing, the viewpoint movement processing shown in FIG. 16 or both may be employed.

  In FIG. 16, when the optical axis P of the camera CM1 is translated to the state of CM2 and CM3, the screen for projecting the three-dimensional virtual space WC such as a golf course changes from SC1 to SC2 and SC3 as in FIG. To do. Camera CM2 translates the optical axis (line of sight P) of camera CM1 to the lower right, and camera CM3 translates the optical axis (line of sight P) of camera CM1 to the upper left.

  The changes in the viewpoint and viewing direction and the viewpoint movement in FIGS. 15 and 16 can be defined by a “view range” determined by the viewpoint position and viewing direction. The “view range” is set by the CPU 101 and the rendering processor 107, and thus the CPU 101 and the rendering processor 107 function as a view range setting means. Similarly, return of the visual field range by the visual field range return instruction object is executed by the CPU 101 and the rendering processor 107, and thus the CPU 101 and the rendering processor 107 function as visual field range return means.

  In FIG. 5, the process of moving and returning the visual field range (viewpoint or line of sight) is executed by the following steps.

  Step S501: First, in the coordinate system of the touch sensor such as the touch panel 116, contact positions with the visual field range movement instruction objects 1010 and 1020 and the visual field range return instruction object 1050 are set. Accordingly, it is possible to detect an instruction to the visual field range movement instruction objects 1010 and 1020 or the visual field range return instruction object 1050 by the indicator 1200.

  Step S502: The visual field range movement instruction objects 1010 and 1020 and the visual field range return instruction object 1050 are displayed on the display unit 112 at the contact positions set in Step S501.

  Step S503: Following step S502, information such as the current viewpoint position and line-of-sight direction is stored and used as information for returning the visual field range. Information on the viewpoint position and the line-of-sight direction is stored in the system memory 102 in the information processing apparatus 100. That is, the system memory 102 functions as viewpoint storage means.

  Step S504: Following step S503, it is determined whether or not the indicator 1200 is in contact with the touch panel 116. When the indicator 1200 is in contact with the touch panel 116, the process proceeds to step S505, and when it is not in contact, the process jumps to step S510.

  Step S505: The contact position of the indicator 1200 is detected, and it is determined which object is indicated.

  When the rapid movement button 1012 in the visual field range left movement button 1010 is pressed, the process proceeds to step S506. When the slow movement button 1014 is pressed, the process proceeds to step S507, and the rapid movement button 1022 in the visual field range right movement button 1020 is pressed. If YES in step S509, the flow advances to step S509. If the slow movement button 1024 is pressed, the flow advances to step S508.

  If the visual field range return instruction object 1050 is pressed, the process proceeds to step S512, and if no object is specified, the process proceeds to step S513.

  Step S506: The visual field range is moved to the left at a relatively high speed, and the process proceeds to Step S510.

  Step S507: The visual field range is moved to the left at a relatively low speed, and the process proceeds to Step S510.

  Step S508: Move the visual field range to the right at a relatively low speed, and proceed to Step S510.

  Step S509: Move the visual field range to the right at a relatively high speed, and proceed to Step S510.

  Step S510: In response to the visual field range set in steps S506 to S509, display positions of the visual field range movement instruction objects 1010 and 1020 and the visual field range return instruction object 1050 are set, and the process proceeds to step S511.

  Step S511: An image is generated and displayed in accordance with the visual field range set in steps S506 to S510. Next, the process returns to step S504.

  Step S512: When the visual field range return instruction object 1050 is pressed, the information on the viewpoint position and the line-of-sight direction stored in step S503 is read out, and the visual field range is returned based on this information, and then the process ends.

  Step S513: When no object is instructed, the process proceeds to a visual field range return type process to be described later.

  The image generation programs of FIGS. 2, 3, and 5 are referred to as a visual field range non-returning process because the visual field range return processing is not executed until the cup position instruction object 1050 is pressed.

  In the field-of-view range non-return type processing, since a movement button that moves only in a predetermined direction (single direction) is provided, it is possible to set the viewpoint and viewing direction according to the player's preference. In addition, since the game can be shifted to the game while maintaining the set state, it is possible to play with an advantageous viewpoint and viewing direction.

  The visual field range movement instruction objects 1010 and 1020 are not limited to the above configuration. For example, as shown in FIG. 6, the movement instruction object 1010 includes a left direction rapid movement button 1012 and a slow movement button 1014. A slow movement button 1016 in the right direction may be provided, and the movement direction object 1020 may be provided with a slow movement button 1026 in the left direction in addition to the sudden movement button 1022 and the gentle movement button 1024 in the right direction.

  For example, when the visual field range is moved to the left by the rapid movement button 1012 and the slow movement button 1014 to precisely set the visual field range, it may be necessary to move the visual field range too much by using the rapid movement button to return the visual field range. There is. At this time, if the operation shifts to the operation of the visual field range movement instruction object 1020, the movement amount of the indicator in the left-right direction becomes large and the operation becomes difficult. On the other hand, if the rightward movement is executed by the slow movement button 1016 provided in the visual field range movement instruction object 1010, the amount of movement of the indicator is small and fine adjustment is possible. It is easy to return to the operation.

  Similarly, when the visual field range is precisely set by moving the visual field range to the right by the sudden movement button 1022 and the slow movement button 1024, the slow movement button 1026 provided in the visual field range movement instruction object 1020 is used to move the left direction. If movement is executed, precise setting is easy.

Next, a second embodiment of the information processing apparatus and the image generation program according to the present invention will be described with reference to the drawings. In the second embodiment, the visual field range return type process is executed. The information processing apparatus of FIG. 1 in the embodiment has the same configuration as that of the embodiment 1, and FIGS. 2 and 3 showing the screen configuration of the game and the description thereof, FIGS. 15 and 16 relating to the movement of the viewpoint and the movement of the viewing direction and the Since the description is the same as that of the first embodiment, the description is omitted.
[Image generation program: Field-of-view range return processing]
The image generation program according to the second embodiment is a process for moving the visual field return type viewpoint or viewing direction, and the visual field range is moved on the premise that the visual point is always restored.

  In the visual field range return type processing, the visual field range is temporarily moved to automatically return, and an operation such as pressing the cup position indicating object 1050 is not necessary for the return of the visual field range.

  The operation of the visual field range return type processing will be described with reference to FIGS.

  In FIG. 7, an arbitrary line of sight movement is possible by moving the indicator 1200 as shown in FIG. 8 while bringing the indicator 1200 such as a finger into contact with the touch panel 116.

  In FIG. 7, the player 1000 is taking a shot, and a display 1300 showing the entire course is provided on the screen.

  In FIG. 8, the indicator 1200 is moved to the right of the position in FIG. 7 (indicated by reference numeral 1201). Accordingly, the visual field range moves to the right, while the virtual space entering the field of view moves to the left.

  In FIG. 9, the indicator 1200 is moved further to the right (indicated by reference numeral 1202) than the position of FIG. Accordingly, the visual field range is greatly moved to the right, and the virtual space entering the field of view is greatly moved to the left.

  In FIG. 10, it moves upward (reference numeral 1203) from the position of the indicator 1200 of FIG. Along with this, the visual field range moves upward, and the virtual space that enters the visual field moves downward.

  In FIG. 11, the indicator 1200 is further moved upward (indicated by reference numeral 1204) from the position of FIG. Along with this, the visual field range is greatly moved upward, and the virtual space entering the field of view is greatly moved downward.

  In the above description, the indicator 1200 gives the line of sight movement (rotation) in the X direction (around the Y axis) or the Y direction (around the X axis).

  In FIG. 12, the indicator 1200 moves diagonally to the upper right (indicated by reference numeral 1205) from the position of FIG. Along with this, the visual field range moves diagonally to the upper right, while the virtual space entering the field of view moves in the lower left direction.

  When the indicator 1200 is moved away from the touch panel 116 after the operation of moving the visual field range as shown in FIGS. 8 to 12, the screen returns to the state of FIG. 7 where the indicator 1200 is first contacted as shown in FIG. .

  The movement of the visual field range can be performed without losing sight of the initial state.

  In addition, since the visual field range can be restored simply by separating the indicator 1200 from the touch panel 116, it is extremely effective for temporarily moving the visual field range.

  FIG. 14 shows a second embodiment of the image generation program. The process in FIG. 14 corresponds to step S513 in FIG. 5. In order to clarify the flow of the process, steps S503, S504, and S512 similar to those in the first embodiment are also displayed in FIG. Subsequent to step S504, the following processing is executed.

  Step S1401: The contact position of the indicator 1200 is detected, and either the visual field range movement instruction object (the visual field range left movement button 1010 or the visual field range right movement button 1020) or the visual field range return instruction object 1050 is designated. Judge whether or not. When any one of these objects has been instructed, the process proceeds to step S1407, and when any object has not been instructed, the process proceeds to step S1402.

  Step S1402: The coordinate value of the touch panel 116 at the position where the indicator 1200 is in contact is acquired and stored, and the process proceeds to Step S1403.

  Step S1403: It is determined whether there is any stored coordinate value of the position where the last time the indicator 1200 touched the touch panel 116. If the stored coordinate value exists, the process proceeds to step S1404. If the coordinate value is not stored, the process returns to step S504 (touch sensor contact determination).

  Step S1404: Based on the difference between the coordinate value stored this time and the coordinate value stored last time, the movement amount and the movement direction are calculated, and the process proceeds to step S1405.

  The movement amount is detected by the touch panel 116 and the CPU 101. Accordingly, the touch panel 116 and the CPU 101 function as a movement amount detection unit.

  Step S1405: Based on the movement amount and movement direction calculated in step S1404, the movement direction of the visual field range is calculated, and a visual field range including a new viewpoint position or line-of-sight direction is set. Thereafter, the process proceeds to step S1406.

  Step S1406: An image corresponding to the visual field range calculated in step S1405 is generated and displayed. Thereafter, the process returns to step S504.

  Step S1407: The process proceeds to the visual field range non-return type process.

  In the above visual field range return type processing, the visual field range on the two-dimensional plane can be set by a single operation to move the indicated position of the touch panel according to the player's preference, and the course outside the display area of the screen is to be looked over You can quickly move to the approximate field of view you want to see. When such a temporary observation is completed, it is generally preferable to return the viewpoint. However, since the visual field range is automatically restored when the indicator 1200 is released from the touch panel 116, another operation is performed to return the visual field range. Is not required. Therefore, extremely delicate operation performance is realized.

  Next, a third embodiment of the information processing apparatus and the image generation program will be described with reference to the drawings.

  The third embodiment may execute a demo that reproduces the play of the player 1000. Further, the information processing apparatus of FIG. 1 in the third embodiment has the same configuration as that of the first embodiment, and FIGS. 2 and 3 showing the game screen configuration and the description thereof, and FIGS. Since the description is the same as that of the first embodiment, the description is omitted.

[Image generation program: Demo speed adjustment by indicator speed]
FIG. 17 shows a screen display when the demonstration is executed, and the player's play of the player 1000 can be observed from various viewpoints, such as reproducing the flight state of the ball 1094 by the immediately preceding shot with a bird's-eye view image. As a result, it is possible to appreciate the playing situation and to extract reflection materials.

  The play status is stored in the system memory 102 as a process of the image generation program, and the demo is reproduced as a moving image by sequentially displaying the two-dimensional images at predetermined time intervals by the image generation program. At this time, the system memory functions as a processing storage unit, and the image generation unit 117 functions as a moving image reproduction unit.

  The demonstration can be executed by operating the mode switching button 1040 shown in FIGS.

  FIG. 18 shows a third embodiment of the image generation program executed by the information processing apparatus of FIG. In the third embodiment, a golf game demo can be played at a desired speed.

  In FIG. 18, the demo reproduction is executed by the following steps.

  Step S1801: First, it is determined whether or not the indicator 1200 is in contact with the touch panel 116. If the indicator 1200 is in contact with the touch panel 116, the process proceeds to step S1802, and if not, the process jumps to step S1805.

  Step S1802: The contact position of the indicator 1200 is detected, and it is determined whether any one of the visual field range left moving button 1010, the visual field range right moving button 1020, or the visual field range return instruction object 1050 is instructed. When any one of these objects has been instructed, the process proceeds to step S513 (FIG. 5), and when any object has not been instructed, the process proceeds to step S1803.

  Step S1803: It is determined whether the current state is that a demonstration is being executed or a normal game operation input is being accepted. When the game operation input is being received, the process proceeds to step S1810, and when the demonstration is being executed, the process proceeds to step S1804.

  Step S1804: It is determined whether or not the current demo playback speed is maximum, that is, the number of playback frames is minimum. When the demo playback speed is maximum, the process proceeds to step S1807, and when it is not maximum, the process proceeds to step S1806.

  Step S1805: The demo is played back at a predetermined speed when the playback speed is not specified.

  Step S1806: The number of frames is coarsened so that the demo playback speed is increased by one step from that point, and the process proceeds to step S1808. That is, by repeating steps S1801 to 1806 during the demonstration reproduction, the reproduction speed increases according to the time for which the indicator 1200 is in contact with the touch panel 116.

  In a normal video game, an image is displayed every 1/60 seconds, and in the golf game, when the player 1000 shots the ball 1094 and then the ball 1094 flies, lands, and generates a video until it stops, Images in which the time from the shot until the ball stops are drawn every 1/60 seconds are sequentially displayed. When the indicator 1200 is not in contact with the touch panel 116, for example, such real-time video playback is executed (step S1805). On the other hand, when the indicator 1200 is in contact with the touch panel 116, an image having an interval longer than 1/60 seconds, for example, 1/30 seconds, 1/10 seconds, or the like is displayed every 1/60 seconds. Can increase the playback speed.

  When the indicator 1200 is continuously in contact with the touch panel 116, an image having a longer real time interval than that of the previous step S1806 is generated and displayed at an interval of 1/60 second, so that image reproduction is accelerated. Is done.

  Step S1807: The demo is reproduced while maintaining the current maximum reproduction speed, and the process proceeds to step S1808.

  Step S1808: The number of demo frames reproduced in steps S1805 to S1807 is stored, and the process proceeds to step S1808.

  Step S1809: It is determined whether or not the moving image to be reproduced in the demo has ended. When it is finished, the process is finished as it is, and when the demonstration reproduction is to be continued, the process returns to step S1801.

  Step S1810: The process shifts to the visual field range non-return type process of FIG.

  As described above, since the demonstration execution speed is set according to the contact time of the indicator 1200 with the touch panel 116, the adjusting operation is extremely easy. Further, if the indicator 1200 is kept touching while viewing the screen, the execution speed increases, so that the adjustment content matches the operating experience.

The demo speed adjustment method is not limited to the process of FIG. 18, and the playback speed is adjusted according to the amount of movement of the indicator 1200 on the touch panel 116 as shown in the flowchart of FIG. 19, and the touch panel as shown in the flowchart of FIG. When the pressing force to 116 can be measured, various modifications such as adjusting the reproduction speed by the contact pressure to the indicator 1200 are possible.
[Demo speed adjustment by the amount of indicator movement]

  In FIG. 19, the demonstration reproduction speed adjustment based on the pointer movement amount is executed by the following steps.

  Steps S1901 to S1905: Processing similar to that in steps S1801 to S1805 in FIG. 18 is executed. After the process of step S1905, the process proceeds to step S1910. In step S1904, the process proceeds to step S1907 when the demo playback speed is maximum, and the process proceeds to step S1906 when it is not maximum.

  Step S1906: It is determined whether or not there is a stored coordinate value of the position where the last time the indicator 1200 touched the touch panel 116. If the stored coordinate value exists, the process proceeds to step S1908. If the coordinate value is not stored, the process returns to step S1901 (touch sensor contact determination).

  Step S1907: The demo is reproduced while maintaining the current maximum reproduction speed, and the process proceeds to step S1910.

  Step S1908: Based on the difference between the coordinate value stored this time and the coordinate value stored last time, the movement amount and the movement direction are calculated, and the process proceeds to step S1909.

  Step S1909: Based on the movement amount and movement direction calculated in step S1908, the demo playback speed is calculated and the demo is played back. Thereafter, the process proceeds to step S1910.

  Step S1910: The number of demo frames reproduced in steps S1905 to S1909 is stored, and the process proceeds to step S1911.

  Step S1911: It is determined whether or not the moving image to be reproduced in the demo has ended. When it is finished, the process is finished as it is, and when the demo reproduction is to be continued, the process returns to step S1901.

Step S1912: Similar to step S1810 in FIG.
[Demo speed adjustment by indicator contact pressure]

  In FIG. 20, the demonstration reproduction speed adjustment by the indicator contact pressure is executed by the following steps.

  Steps S2001 to S2005: The same processing as steps S1801 to S1805 in FIG. 18 is executed. After the process of step S2005, the process proceeds to step S2009. In step S2004, the process proceeds to step S2007 when the demo playback speed is maximum, and the process proceeds to step S2006 when it is not maximum.

  Step S2006: The contact pressure of the indicator 1200 on the touch panel 116 is acquired, and the process proceeds to step S2008.

  Step S2007: The demo is reproduced while maintaining the current maximum reproduction speed, and the process proceeds to step S2009.

  Step S2008: The demonstration execution speed is calculated from the pressure acquired in step S2006, the demonstration is reproduced, and the process proceeds to step S2009.

  Step S2009: The number of demo frames reproduced in steps S2005 to S2008 is stored, and the process proceeds to step S2010.

  Step S2010: It is determined whether or not the moving image to be reproduced in the demo has ended. When it is finished, the process is finished as it is, and when the demo reproduction is to be continued, the process returns to step S2001.

  Step S2011: Similar to step S1810 in FIG.

  Since the demonstration execution speed is set by the pressure of the indicator 1200 on the touch panel as described above, the adjustment operation is extremely easy. Further, when the indicator 1200 is pressed strongly while looking at the screen, the execution speed increases, so that the adjustment content matches the operating experience.

  The present invention is not limited to the above-described embodiments, and can be applied to various games, image display devices, and systems that require moving and returning of the visual field range in the virtual space, and further, natural images are displayed as images to be displayed. Various images are included. For example, in a monitoring system in which the position and shooting direction of a monitoring camera can be moved, it is effective in moving the field of view, returning, reproducing, etc. of a shot or shot image.
