Description

Technical Field

[0001] The present invention relates to an image display device and an operation control method thereof, and more particularly to a game device for displaying game images and an operation control method thereof.

Background Art

[0002] In order to suppress power consumption when displaying an image on a display, a technique for adjusting the brightness of a part of the displayed image is known. For example, in a portable terminal device that scrolls a content image by a flick operation, when an image other than the image displayed on the display scrolls the display after the flick operation, a technique for suppressing power consumption by reducing the brightness of the image is known (Patent Document 1).

[0003] Also, in order to improve the visibility of a display image regardless of the brightness around the display, a technique for adjusting the brightness of the display image according to the brightness around the display is known. For example, in a liquid crystal television device provided with a light receiving element on the front side of a liquid crystal display element panel, a technique for changing the voltage applied to the liquid crystal layer of the liquid crystal display element according to the ambient brightness detected by the light receiving element and changing the brightness of the entire display image is known (Patent Document 2).

[0004] In recent years, further diversification of image display methods has been demanded, and an image display device in which a plurality of regions capable of independently displaying images are provided in an image display region of a display has been studied. In this image display device, a method for improving the visibility of the display image in each region is required. However, with the above conventional image display technology, it has been difficult to sufficiently enhance the visibility of the display image in each region.

FIG. 14 is a perspective view schematically showing a game device according to the first embodiment of the present invention.

[0027] 1. Overview of the game First, the game executed by the game device 1 of the present embodiment will be described. The game device 1 can execute, for example, a battle game or a role-playing game using the recording medium 11. Specifically, the game device 1 acquires character information (hereinafter referred to as "character information") recorded on the recording medium 11 by scanning the recording medium 11. Thereafter, the game device 1 displays an image of the character on the display unit 6. Thereby, the game device 1 can execute a battle game in which the character battles against an enemy (opponent) character. After the game ends, a new recording medium 11 is dispensed from the game device 1. Note that the game executed by the game device 1 is not limited to the above-described game.

[0028] 2. Recording medium The recording medium 11 used in the game device 1 of this embodiment is not particularly limited as long as it can store character information. Such a recording medium 11 is formed in a card shape, for example, as shown in FIG. 2. This recording medium 11 has a two-dimensional code 111 on its surface. Character information, item information, etc. are recorded in this two-dimensional code 111. Examples of the two-dimensional code 111 include QR Code (registered trademark) and Zcode (registered trademark). In the case of Zcode, the information is recorded so that it can be identified under invisible light (infrared rays). Note that the recording medium 11 may be a game IC card that stores player information and character information. Also, the recording medium 11 may be formed in the shape of a gold coin, a circle, a square, etc.

[0029] 3. Game device Next, the game device will be described. As shown in FIG. 1, the game device 1 of this embodiment includes two game devices (the first sub-game device 1A and the second sub-game device 1B) provided adjacent to each other. This game device 1 has one display unit 6 and is controlled by one control unit 8. Therefore, the size of the entire game device 1 can be reduced. Thereby, the cost of the entire game device 1 can be reduced. The game device 1 of this embodiment is not limited to the configuration in which two game devices are provided adjacent to each other (2-in-1 configuration), and may have a configuration in which three or more game devices are provided adjacent to each other.

[0030] At first glance, the game device 1 of this embodiment appears to have two game devices arranged adjacent to each other. However, the game device 1 is such that these two game devices are connected to form one game device 1. Therefore, each player (user) can execute play on each sub-game device, or can also execute one game play in cooperation. Such a game device 1 has a housing 2, an operation unit 3, a reading unit 4, a speaker 5, a display unit 6, an illuminance detection unit S, a storage unit 7, a control unit 8, and a communication unit 9, as shown in FIGS. 1 and 3. Hereinafter, the configuration of each unit will be described.

[0031] Note that the housing 2, operation unit 3, reading unit 4, and speaker 5 of the game device 1 are the same as the sub-housing 2A, first sub-operation unit 3A, sub-reading unit 4A, and sub-speaker 5A for the first sub-game device 1A, and the sub-housing 2B, second sub-operation unit 3B, sub-reading unit 4B, and sub-speaker 5B for the second sub-game device 1B. Therefore, hereinafter, only each part of the game device 1 will be described as a representative.

[0032] <Housing> The housing 2 has a function of installing or storing each member of the game device 1. As shown in FIG. 1, the housing 2 is formed in a substantially rectangular parallelepiped shape, but is not limited thereto. The housing 2 may be composed of one housing (twin housing), or may be configured by connecting sub-housings for each sub-game device. In the case of a twin housing, the housing 2 is formed symmetrically left and right, and the central portion (especially the front surface) of the housing 2 may be recessed inward. Thereby, it can be made to look like there are two game devices at a glance to the player.

[0033] The housing 2 has a maintenance door 21 for a game administrator to maintain and manage the operation rate of the game device 1, the distribution rate of the recording medium 11, etc. The door 21 is provided on the front surface of the housing 2. The door 21 has a function of accessing a maintenance panel 22 housed in the housing 2. As shown in FIG. 14, a maintenance panel (electronic device) 22 is arranged on the back surface of the door 21. The maintenance panel 22 is composed of buttons for a game administrator to test and manage the game device 1. With such a configuration, for example, when it is desired to reset the game of the first sub-game device 1A, the game of the first sub-game device 1A can be independently managed without interrupting the play in the second sub-game device 1B. Note that the door 21 is not an essential element of the game device 1.

[0034] <Operation unit> The operation unit 3 has a function of receiving operation inputs made by the player to execute the game. The operation unit 3 is composed of four push buttons 31 and two rectangular operation fields 32. The push buttons 31 are provided symmetrically on the front side of the upper surface of the housing 2. The operation fields 32 are provided on the upper surface of the housing 2, on the back side of the push buttons 31. The shape and position of the operation fields 32 are not particularly limited, and each may be in the shape of a rod, a circle, at a position between the push buttons 31, or in front of the push buttons 31. Such an operation field 32 is a field where the player can install and move the recording medium 11. The operation field 32 is configured such that the reading unit 4 described later can read the recording medium 11.

[0035] The operation unit 3 includes a first sub-operation unit (first operation unit) 3A for the first sub-game device 1A and a second sub-operation unit (second operation unit) 3B for the second sub-game device 1B. The first sub-operation unit 3A and the second sub-operation unit 3B can be operated independently and can receive different operation inputs simultaneously. Thereby, different operations can be executed by the first sub-game device 1A and the second sub-game device 1B.

[0036] <Reading unit> The reading unit 4 has a function of reading information on the recording medium 11 installed on the operation field 32. The reading unit 4 is provided inside the housing 2, below the operation field 32. Such a reading unit 4 is composed of, for example, an imaging device (camera) and an infrared light source. The infrared light source of the reading unit 4 irradiates infrared light on the two-dimensional code 111 of the recording medium 11 from below the operation field 32. In this state, by the imaging device imaging the two-dimensional code 111 of the recording medium 11, the information recorded in the two-dimensional code 111 of the recording medium 11 can be read. Note that the reading unit 4 may be arranged anywhere inside the housing 2 as long as the imaging device can image the operation field 32. Also, the reading unit 4 may be composed of only the imaging device.

[0037] <Speaker> The speaker 5 has a function of outputting various sounds. The speaker 5 is provided under the display unit 6 at the back of the upper surface of the housing 2. The number of speakers 5 is not particularly limited and may be one or a plurality of two or more. In the present embodiment, two speakers 5 are provided on both sides of the back of the upper surface of the housing 2 corresponding to each sub-game device. The sounds output by the speaker 5 include music and sound effects stored in the storage unit 7.

[0038] <Display unit> The display unit 6 has a function of displaying a game image (a predetermined image). As shown in FIG. 1, the display unit 6 is provided on the speaker 5 on the upper surface of the housing 2. The display unit 6 is composed of a single display panel, but may be a touch panel. Further, as shown in FIG. 1, the display unit 6 is formed in a rectangular shape, but is not limited thereto and may be formed in a circular shape or a triangular shape.

[0039] The display unit 6 has a full-screen area 61 for displaying a game image and a frame 62 provided along the outer edge of the full-screen area 61. The full-screen area 61 includes an individual area 611 and a partition area 612. As shown in FIG. 5, the full-screen area 61 has a function of displaying a game image on the entire display unit 6. When the player of the first sub-game device 1A and the player of the second sub-game device 1B cooperate or play a battle game, the game image is displayed in the full-screen area 61.

[0040] The individual area 611 includes an area (first area) 611A for displaying a game image for the first sub-game device 1A and an area (second area) 611B for displaying a game image for the second sub-game device 1B. As shown in FIGS. 4 and 6, these areas 611A and 611B are configured to have the same area as each other via a partition area 612. Thereby, it can be made to appear to the player that there are two game devices at a glance. However, the area of either one of the areas may be configured to be smaller than the area of the other area. For example, when a battle game is being executed between the first sub-game device 1A and the second sub-game device 1B, if the area of the area 611A for the first sub-game device 1A is large, the game image for the first sub-game device 1A will be displayed large. In such a case, an impression that the player of the first sub-game device 1A is dominant can be given to the player.

[0041] The first area 611A is provided corresponding to the first sub-operation unit 3A of the first sub-game device 1A. The first area 611A is formed in a rectangular shape, but is not limited thereto. The second area 611B is provided corresponding to the second sub-operation unit 3B of the second sub-game device 1B. The second area 611B is formed in a rectangular shape, but is not limited thereto. The first area 611A may display the same image as the image displayed in the second area 611B, or may display a different image. Also, the first area 611A and the second area 611B can each independently display an image.

[0042] The partition area (third area) 612 has a function of partitioning the first area 611A and the second area 611B. Therefore, the partition area 612 is provided between the first area 611A and the second area 611B. The shape of the partition area 612 is not particularly limited, and may be a long shape (FIG. 4), a rectangular shape, a substantially trapezoidal shape (FIG. 6), or the like. The area of the partition area 612 is not particularly limited, and may be larger or smaller than the area of the first area 611A or the second area 611B. The partition area 612 may be further divided into a plurality of areas.

[0043] For example, as shown in FIG. 4, the partition region 612 may be divided along its short side direction and have two partition regions. That is, the partition region 612 may have a first partition region 612A for the first region 611A and a second partition region 612B for the second region 611B. Also, as shown in FIG. 6, the partition region 612 may be divided along its long side direction and have two partition regions. That is, the partition region 612 may have a third partition region 612C for game images and a fourth partition region 612D for character images. By doing so, a plurality of images, different from each other, can be displayed in the partition region 612.

[0044] The frame body 62 is provided on the speaker 5 or the housing 2. The frame body 62 is formed in a rectangular shape, but is not limited thereto. For example, the frame body 62 may be formed in any shape such as a circular shape or an elliptical shape. The frame body 62 has a joint portion 621 formed so as to be recessed inward at the center of its long side. Due to this joint portion 621, the frame body is formed symmetrically about the left and right. Therefore, the display portion 6 can be shown as two display portions, such as the sub-display portion 6A for the first sub-game device 1A and the sub-display portion 6B for the second sub-game device 1B.

[0045] The frame body 62 may include a first frame member 62A for the first sub-game device 1A and a second frame member 62B for the second sub-game device 1B. As shown in FIGS. 4 to 6, the first frame member 62A and the second frame member 62B are formed in a substantially "C" shape. And one end and the other end of the first frame member 62A are in contact with one end and the other end of the second frame member 62B, respectively, to form the joint portion 621. With such a configuration, the first frame member 62A and the second frame member 62B are arranged symmetrically about the joint portion 621. Therefore, the display portion 6 can be shown as two display portions.

[0046] As shown in FIG. 4, one end and the other end of the first frame member 62A are provided facing each other. Therefore, an image (partition image) identical to the appearance of the short side of the frame body 62 can be displayed in the first partition region 612A from one end to the other end. As a result, the first frame member 62A and the partition image are connected to form an annular frame member (the first frame member 62A). That is, the partition image appears to be integrally formed with the first frame member 62A. Therefore, the player can be made to recognize that there are individual sub-display units 6A in the display unit 6.

[0047] On the other hand, one end and the other end of the second frame member 62B are provided facing each other. Therefore, an image (partition image) identical to the appearance of the short side of the frame body 62 can be displayed in the second partition region 612B from one end to the other end. As a result, the second frame member 62B and the partition image are connected to form an annular frame member (the second frame member 62B). That is, the partition image appears to be integrally formed with the second frame member 62B. Therefore, the player can be made to recognize that there are individual sub-display units 6B in the display unit 6.

[0048] In this way, the first frame member 62A and the partition image constitute the frame body 62 for the first sub-game device 1A. Also, the second frame member 62B and the partition image constitute the frame body 62 for the second sub-game device 1B. Thereby, one frame body 62 can be divided into two frame members 62A and 62B, and although it is one game device 1, an impression that there are two game devices can be given to the player. And the first frame member 62A (the first region 611A) and the first sub-operation unit 3A, and the second frame member 62B (the second region 611B) and the second sub-operation unit 3B are arranged symmetrically with respect to the partition image as the central axis. Therefore, an impression that there are two game devices can be given to the player.

[0049] <Illuminance detection unit> The illuminance detection unit S has a function of detecting the illuminance (luminance, chromaticity, etc.) around the display unit 6. The illuminance detection unit S is, for example, built into the upper long side of the frame body 62 of the display unit 6, and in the present embodiment, it is provided near the upper joint portion 621 of the first frame member 62A. As such an illuminance detection unit S, for example, an optical sensor, an imaging device, etc. are used, but in the present embodiment, an optical sensor is used. The optical sensor acquires the incident light as luminance / chromaticity signals such as three stimulus values X, Y, Z, etc., and provides this signal information to the storage unit 7 (Fig. 7). Note that a plurality of illuminance detection units S may be built into the frame body 62. In this case, based on the signal information from the plurality of illuminance detection units S, adjustment of predetermined parameters of the partition image is performed, so that more accurate adjustment becomes possible. Further, the illuminance detection unit S may be configured to be externally attached to the frame body 62. Furthermore, when an imaging device is used as the illuminance detection unit S, for example, it may be provided on the back side of the operation field 32 of the operation unit 3 to detect the illuminance of the frame body 62 of the display unit 6.

[0050] <Storage unit> Next, the storage unit 7 will be described. The storage unit 7 stores a game program and game data. The game program is a program for causing the game device 1 to execute a game, and is realized by cooperation with hardware. Also, the game data is data related to the game, and includes character data, music data, image data, sound effect data, etc.

[0051] The character data is data such as the name of the character, special move, weapon, strength, etc. The music data is music data flowing from the speaker 5. The music data includes, for example, a plurality of music data such as music by singers and music of the game. The image data is game image data. The game image data includes, for example, data such as character images, background images, and various effect images. The sound effect data is sound data reproduced during game play, and is different from the music data. The sound effect data includes, for example, evaluation sound data flowing according to the operation results of the player.

[0052] In the game device 1 of the present embodiment including the illuminance detection unit S, as shown in FIG. 7, the storage unit 7 stores data for adjusting predetermined parameters of the partition image. First, in advance, using an imaging device or the like, the chromaticity at various brightnesses (luminances) is measured for a plurality of types of frames 62 with different color variations, and is stored in the storage unit 7 as frame information (parameters of the frame). At this time, the location where the luminance and chromaticity are measured is the location where the illuminance detection unit S is provided. In the present embodiment, the luminance (luminance reflectance Y a ) and chromaticity (xy chromaticity coordinates (x a , y a )) based on the CIE XYZ color system are used to calculate the three color attributes (hue, lightness, and chroma) as the "predetermined parameters". However, the "predetermined parameters" may be luminance and chromaticity based on other color systems (for example, RGB color system, Yuv color system, etc.), information regarding other color systems, or signal information of either luminance or chromaticity. Note that the luminance (luminance reflectance Y a ) based on the CIE XYZ color system corresponds to the "lightness" among the three color attributes, and the chromaticity (xy chromaticity coordinates (x a , y a )) based on the CIE XYZ color system corresponds to the "hue" and "chroma" among the three color attributes.

[0053] In addition, the storage unit 7 stores a predetermined threshold value corresponding to each frame information (No. 1, 2, ···). The predetermined threshold value may be the same for all frame information, or may be changed according to the luminance value. For example, as shown in FIG. 7, when the luminance is high (70% of No. 2), the threshold values of luminance and chromaticity are set large, and when the luminance is low (5% of No. 6), it is preferable that the threshold values of luminance and chromaticity are set small. This is because the brighter the surrounding environment, the more the luminance and chromaticity of the objects to be compared may differ to some extent, but they still look the same. On the contrary, the darker the surrounding environment, the more the slight difference in the luminance and chromaticity of the objects to be compared makes them look different.

[0054] The memory unit 7 stores the illuminance (detection value) detected by the illuminance detection unit S. The detected detection value, the above frame information, and the threshold information are provided to the parameter determination means 86 and the parameter adjustment means 87 described later.

[0055] As shown in FIG. 8, the memory unit 7 stores predetermined events. The predetermined events include, as shown in FIG. 8, boss character appearance events, bonus events, intrusion battle events, hit characters, etc. Such predetermined events are stored in association with the display area where the game image should be displayed and the partition image that partitions the display area. For example, the boss character appearance event A is associated such that the display area is only the full screen area 61 and there is no partition image. At this time, as shown in FIG. 5, the image is displayed in the full screen area 61. Also, the boss character appearance event B is associated such that the display areas are the individual area 611 and the partition area 612, and the partition image is the image of the boss character B and the character image of "Power 20%". At this time, as shown in FIG. 6, the partition image is displayed in the partition area 612.

[0056] Furthermore, for example, when one player is playing on the first sub-game device 1A in the full screen area 61 and another player is playing on the second sub-game device 1B, an event is triggered. That is, when the second sub-operation unit 3B of the second sub-game device 1B receives an operation input for an intrusion battle by another player, the event of intrusion battle B is triggered. At this time, the intrusion battle B is associated such that the display areas are the individual area 611 and the partition area 612, and the partition image is a bar image. At this time, as shown in FIG. 4, the partition area 612 displays the partition image.

[0057] Furthermore, when the play is executed on the first sub-game device 1A and the second sub-game device 1B with the recording medium 11 of the same hit character being distributed from the first sub-game device 1A and the second sub-game device 1B, an event is activated. That is, during the play on the first sub-game device 1A, when the player of the second sub-game device 1B executes an action, an event of the hit character is activated. At this time, for example, as shown in FIG. 5, an image is displayed in the entire screen area 61.

[0058] <Control Unit> Next, the control unit 8 will be described. The control unit 8 controls all functions related to the execution of the game. Such a control unit 8 includes, as shown in FIG. 3, an acquisition means 81, a game processing means 82, a display control means 83, a switching means 84, a partitioning means 85, a parameter determination means 86, a parameter adjustment means 87, and a sound output control means 88.

[0059] (Acquisition Means) The acquisition means 81 has a function of acquiring information on operation inputs by the player, character information and game information of the recording medium 11, etc. The acquisition means 81 acquires information on operation inputs by the pressing of the push button 31 by the player. This can receive information on operation inputs simultaneously from the first sub-operation unit 3A and the second sub-operation unit 3B. Such information on operation inputs includes, for example, information related to interrupt play and information related to character selection. In addition, the acquisition means 81 acquires character information etc. read by the reading unit 4. Further, it acquires various information acquired via the communication unit 9 described later.

[0060] (Game Processing Means) The game processing means 82 has a function of processing the information acquired by the acquisition means 81 and the progress of the game. For example, the game processing means 82 determines the information on the game image stored in the storage unit 7 and provides it to the display control means 83. The game processing means 82 determines the sound information and provides it to the sound output control means 88. In addition, the game processing means 82 determines and activates a predetermined event. In this way, the game processing means 82 processes the progress of the entire game.

[0061] Here, the determination of a predetermined event by the game processing means 82 may be performed randomly, periodically, by receiving an operation input from the player, or by the number (multiple sheets) of the winning recording media 11. Further, as shown in FIG. 7, the game processing means 82 specifies a specific partition image corresponding to a predetermined event, but can also be determined to display a predetermined image other than the partition image.

[0062] (Display control means) The display control means 83 has a function of controlling the display of all images related to the game. That is, the display control means 83 controls the display of the game image information provided by the game processing means 82 and the display of the partition image by the partition means 85. For example, as shown in FIG. 4, the display control means 83 independently controls the display of the game image in both the first region 611A and the second region 611B of the display unit 6. Further, as shown in FIG. 5, the display control means 83 controls the display of the game image in the entire screen region 61. Further, the display control means 83 controls the display of a linear partition image (FIG. 4), a partition image such as a game image or a character image (FIG. 6) in the partition region 612. Further, when information for adjusting a predetermined parameter (hue, brightness, and saturation) of the partition image is provided by the parameter adjustment means 87, the display of the partition image with the predetermined parameter adjusted is controlled. In this way, the display control means 83 can control to separately display a predetermined image in each region of the display unit 6.

[0063] (Switching means) The switching means 84 has a function of mutually switching between the full-screen area 61 and the individual area 611 when a predetermined event is triggered by the game processing means 82 or when the operation unit 3 receives predetermined input information. Specifically, when the game play is being executed, the switching means 84 switches the display area of the display unit 6 from the individual area 611 to the full-screen area 61, or from the full-screen area 61 to the individual area 611, upon the triggering of the predetermined event or the reception of the input information. That is, when there is a predetermined event, the switching means 84 refers to the event table in FIG. 8 and controls to switch the display area to the display area corresponding to the event.

[0064] Normally, the game device 1 is set such that each sub-game device executes a game individually. Therefore, a partition image is displayed in the partition area 612 between the first area 611A and the second area 611B. Thus, when a predetermined event is triggered, the switching means 84 can simultaneously execute switching the display area from the first area 611A to the full-screen area 61 and switching the display area from the second area 611B to the full-screen area 61.

[0065] On the other hand, when each sub-game device is set to execute a game in cooperation, a game image is displayed in the full-screen area 61. Therefore, when a predetermined event is triggered, the switching means 84 can switch the display area from the full-screen area 61 to the individual areas 611 (the first area 611A and the second area 611B) and the partition area 612.

[0066] (Partition means) The partition means 85 has a function of partitioning between the first area 611A and the second area 611B and is composed of a partition image. Specifically, when the switching means 84 switches the display area, the partition means 85 refers to the information table in FIG. 8 and specifies the partition area 612 and the partition image corresponding to the event. The partition means 85 provides the specified partition area 612 and the information of the partition image to the display control means 83.

[0067] The partition image is not particularly limited as long as it can partition the first region 611A and the second region 611B. Therefore, the partition image may be a long image (bar image), an annular image, a curved image, a game image, a predetermined character image, or the like. For example, as shown in FIG. 8, when the event of the intrusion battle B is activated, the partitioning means 85 specifies the bar image of the partition image and the display area. The partitioning means 85 provides this information to the display control means 83. In this case, as shown in FIG. 4, bar images are displayed in the first partition region 612A and the second partition region 612B, respectively. At this time, the bar image is composed of the same image as the appearance of the opposing frame member. Thereby, due to the first frame member 62A and the bar image, it is visually recognized that the first frame member 62A is formed in a frame shape. Also, due to the second frame member 62B and the bar image, it is visually recognized that the second frame member 62B is formed in a frame shape. Therefore, it is possible to make the player recognize that there are two game devices.

[0068] Also, as shown in FIG. 8, when the event of the appearance of the boss character A or the hit character is activated, the partitioning means 85 determines that there is no partition image to be displayed. Therefore, the partitioning means 85 provides the display control means 83 with information for erasing the displayed partition image. In this case, as shown in FIG. 5, the partition image is erased, and a game image is displayed in the entire screen area 61. Thereby, two players can enjoy the game simultaneously on one display unit 6.

[0069] Also, as shown in FIG. 8, when the event of the appearance of the boss character B is activated, the partitioning means 85 specifies the "boss character B" and "power 20%" of the partition image and the display area. The partitioning means 85 provides this information to the display control means 83. In this case, as shown in FIG. 6, the boss character B is displayed in the third partition region 612C, and the character image of "power 20%" is displayed in the fourth partition region 612D. Thereby, it is possible to inform the player of the power possessed by the boss character B. Note that the layout of the third partition region 612C and the fourth partition region 612D is not particularly limited, and the fourth partition region 612D may be located above the third partition region 612C.

[0070] (Parameter determination means) The parameter determination means 86 determines predetermined parameters (hue, lightness, and chroma) of the partition area 612 to be adjusted according to the illuminance detected by the illuminance detection unit S. Specifically, the parameter determination means 86 refers to the frame information and the detection value among the data tables for parameter adjustment (frame body information, threshold information, detection value) shown in FIG. 7, and determines the predetermined parameters of the partition area 612.

[0071] The parameter determination means 86 calculates the deviation amount (difference) between the frame information (luminance and chromaticity) stored in the storage unit 7 and the detection value (luminance and chromaticity) detected by the illuminance detection unit S based on the data table shown in FIG. 7. For example, referring to the frame information No. 1 in FIG. 7, the luminance Y a value is 50%, while the detected luminance Y b value is 55%. Therefore, the deviation amount of the luminance to be adjusted is 5% (= 55 - 50). Also, the xy chromaticity coordinates (x a , y a ) to be displayed are (0.46, 0.44), while the detected xy chromaticity coordinates (x b , y b ) are (0.52, 0.38). Therefore, the deviation amount of the xy chromaticity coordinates to be adjusted is 0.06 for the x coordinate (= 0.52 - 0.46) and -0.06 for the y coordinate (= 0.38 - 0.44).

[0072] The deviation amounts of hue, lightness, and chroma calculated based on the deviation amounts of luminance and chromaticity calculated in this way are determined as data of the predetermined parameters to be adjusted. The parameter determination means 86 provides the calculated deviation amount to the parameter adjustment means 87. In the above example, the deviation amount is determined so that the luminance and chromaticity of the partition image completely match the luminance and chromaticity of the frame information. However, within the range where the partition image and the frame body 62 are integrally visible, the predetermined parameters to be adjusted may include an error.

[0073] (Parameter adjustment means) The parameter adjustment means 87 has a function of adjusting predetermined parameters (hue, lightness, and chroma) of the partition image displayed in the partition area 612 based on the predetermined parameters determined by the parameter determination means 86. The parameter adjustment means 87 may always adjust the predetermined parameters of the partition image based on the deviation amounts of the hue, lightness, and chroma determined by the parameter determination means 86, or may adjust the predetermined parameters of the partition image only when the deviation amount exceeds the threshold range. In the case of (i) above, the parameter determination means 86 subtracts or adds the deviation amount of the luminance and chrominance (hue, lightness, and chroma) determined by the parameter determination means 86 from the luminance and chrominance of the display data of the currently displayed partition image, so that the luminance and chrominance of the partition image completely match the luminance and chrominance of the frame body information.

[0074] Also, in the case of (ii) above, when the deviation amount of the luminance and chrominance determined by the parameter determination means 86 exceeds the threshold range based on the data table shown in FIG. 7, the parameter determination means 87 adjusts the luminance and chrominance of the partition image in the same manner as in (i) so that they completely match the luminance and chrominance of the frame body information. On the other hand, when the deviation amount is within the threshold range, the predetermined parameters of the partition image are not adjusted. For example, in the case of frame body information No. 1, the deviation amount of the luminance to be adjusted (5%) does not exceed the threshold range, but the deviation amount of the xy chromaticity coordinates to be adjusted (x: 0.06, y: -0.06) exceeds the threshold range, so the parameters of the partition image are adjusted. Also, in the case of frame body information No. 2, although the deviation amount of the luminance to be adjusted (8%) is large, it does not exceed the threshold range, and the deviation amount of the xy chromaticity coordinates to be adjusted (x: -0.09, y: 0.05) also does not exceed the threshold range, so the parameters of the partition image are not adjusted.

[0075] In the game device 1 of the present embodiment, the illuminance detection unit S detects the illuminance around the display unit 6, and adjusts predetermined parameters (such as hue, lightness, and chroma) of the partition image according to the detected illuminance. Specifically, the display unit 6 displays the partition image so that the frame body 62 and the partition image appear integrally according to the detected illuminance. For example, if the game device 1 is installed in a relatively dark place, the brightness (reflectivity) of the frame 62 of the display unit 6 decreases. Therefore, if the partition image of the partition area 612 is displayed with the same brightness as the display image of the individual area 611, the partition image may be too bright, and the frame 62 and the partition image may not be seen as a whole. Also, depending on the color of the lighting in the place where the game device 1 is installed, the frame 62 and the partition image may not be seen as a whole.

[0076] On the other hand, in the game device 1 of the present embodiment, the display unit 6 displays the partition image so that the frame 62 and the partition image can be seen as a whole according to the detected illuminance. Therefore, regardless of the place where the game device 1 is installed, the player can be strongly given the impression that there are two game devices. Also, since the partition image and the frame 62 can be seen more integrally, the visibility of the display images of the individual areas 611A and 611B can be improved.

[0077] When a predetermined parameter of the partition image in the partition area 612 is adjusted at the start of the game, when switching from each individual area 611 to the full screen area 61 by the switching means 84, the parameter adjusting means 87 cancels the adjusted parameter. Also, when switching the display area from the full screen area 61 to the individual areas 611 and the partition area 612 by the switching means 84, the parameter adjusting means 87 adjusts the predetermined parameter of the partition image again.

[0078] (Sound output control means) The sound output control means 88 controls the output of all sounds and music related to the game. Specifically, the sound output control means 88 controls the output of the music and sounds determined by the game processing means 82. By providing the sound output means 88 with sound and music information to the speaker 5, the speaker 5 can output sound and music.

[0079] In addition to the above configuration, the control unit 8 of the present invention may include an appearance change means having a function of changing the appearance of the divider image. The appearance change means can change the appearance of the divider image by receiving an operational input or randomly. For example, if the frame 62 of the display unit 6 of the game device 1 shown in FIG. 1 is changed to another frame having a different appearance (design), the appearance change means can change the appearance of the divider image to match the appearance of the new frame member. The appearance change means can also change the color or design of the divider image identified by the divider means 85 and decorate the divider image with a pre-stored image. This allows the divider image to be changed to match the appearance of the frame member, regardless of its appearance.

[0080] The control unit 8 may also include a mode change means for changing the play mode. The modes include a solo play mode, a competitive play mode, a cooperative play mode, a tournament play mode, etc. The mode change means can change the play mode by receiving an operational input or randomly. The mode change means can execute this mode change at any time. When a mode change occurs, the control unit 8 executes the above-described processing to correspond to the mode change.

[0081] <Communications Department> The communication unit 9 has a function of communicating with an external network (such as a LAN, WAN, or the Internet) or device via a wired or wireless connection. The game device 1 of the present invention may communicate data with other devices, such as other game devices or information terminals, via the communication unit 9. For example, the communication unit 9 can communicate with other devices to obtain music data or game programs. This allows the game programs to be updated, making it possible to provide the latest games. Note that the game device 1 does not necessarily have to have the communication unit 9.

[0082] As described above, the image display device of the present invention has been described as the game device 1. In addition to the above-described respective parts, the game device 1 of the present embodiment also includes a coin insertion slot, a coin return slot, an outlet for the recording medium 11, etc. on the front surface of the housing 2.

[0083] B. Operation Control Method of Image Display Device Next, the operation control method of the image display device of the present embodiment will be described. Hereinafter, for ease of understanding, the case where the image display device is a game device will be described as an example. FIG. 9 is a flowchart showing the flow of game processing of the game device according to the first embodiment of the present invention. FIGS. 10(a) and (b) are flowcharts showing processing related to parameter adjustment of the partition image in the game processing shown in FIG. 9. FIG. 10(a) is a flowchart showing processing for adjusting parameters after displaying a game image on the display unit, and FIG. 10(b) is a flowchart showing processing for adjusting parameters before displaying a game image on the display unit.

[0084] First, the flow of game processing of the game device excluding the processing related to parameter adjustment of the partition image will be described. First, when the player inserts a coin, the display control means 83 controls the display of the game image. As a result, the display unit 6 displays the game image (S1). During the execution of the game by the player, the control unit 8 determines whether or not the game processing means 82 has activated a predetermined event (S2). If the predetermined event is not activated, the process proceeds to step S1, and steps S1 to S2 are repeated. On the other hand, if the predetermined event is activated, the process proceeds to step S3.

[0085] In step S3, the control unit 8 determines whether the game image is being displayed in the individual area 611 (S3). If the control unit 8 determines that the game image is being displayed in the individual area 611, it determines that the game image is being displayed in the first area 611A and the second area 611B, and that a partition image is being displayed in the partition area 612. At this time, the switching means 84 switches the display area of the display unit 6 from the individual area 611 to the full-screen area 61 (S4). Thereafter, the partition image is erased from the partition area 612 (S5). As a result, the display unit 6 displays the game image in the full-screen area 61 (S6), and the process ends.

[0086] On the other hand, in step S3, if the control unit 8 determines that the game image is not being displayed in the individual area 611, it determines that the game image is being displayed in the full-screen area 61. At this time, the process proceeds to step S7. Next, the control unit 8 determines whether to switch the full-screen area 61 to the individual area 611 (S7). If the control unit 8 determines not to switch the full-screen area 61 to the individual area 611, the process proceeds to step S6, and the game image continues to be displayed in the full-screen area 61 (S6). As a result, the process ends.

[0087] On the other hand, if the control unit 8 determines to switch the full-screen area 61 to the individual area 611, the switching means 84 switches the display area from the full-screen area 61 to the individual area 611 (S8). Then, the partitioning means 85 identifies the partition image, and the partition image is displayed (S9). Thereafter, the process proceeds to step S1. In this way, steps S1 to S9 are repeated.

[0088] Next, the process for adjusting the parameters of the partition image will be described. In the present embodiment, as a method for adjusting the parameters of the partition image, (i) a method of adjusting a predetermined parameter of the partition image according to the illuminance around the display unit 6 after or while displaying the game image on the display unit 6, and (ii) a method of adjusting a predetermined parameter of the partition image in advance according to the illuminance around the display unit 6 before displaying the game image on the display unit 6, are included.

[0089] In the method of (i) above, as shown in Fig. 10(a), with the display unit 6 displaying a game image (S1), the illuminance detection unit S detects the illuminance (luminance, chromaticity) around the display unit 6 (S11). The detected illuminance is provided to the storage unit 7, and a data table as shown in Fig. 7 is created. Next, the parameter determination means 86 refers to the data table and determines the deviation amount (predetermined parameter to be adjusted) between the frame information and the detected value (S12).

[0090] Next, the parameter adjustment means 87 refers to the data table and determines whether the deviation amount exceeds the threshold range (S13). When the parameter adjustment means 87 determines that the deviation amount exceeds the threshold range, it adjusts the deviation amount from the luminance and chromaticity of the image data of the partition image currently being displayed (S14). Thereafter, the display unit 6 displays the partition image with the adjusted hue, lightness, and saturation (S15). On the other hand, in step S13, when the parameter adjustment means 87 determines that the deviation amount does not exceed the threshold range, that is, the deviation amount is within the threshold range, the parameter adjustment means 87 does not adjust the hue, lightness, and saturation of the partition image of the display unit 6.

[0091] In the method of (ii) above, as shown in Fig. 10(b), when the player inserts a coin, before the display unit 6 displays a game image, the illuminance detection unit S detects the illuminance (luminance, chromaticity) around the display unit 6 (S11). The detected illuminance is provided to the storage unit 7, and a data table as shown in Fig. 7 is created. Next, the parameter determination means 86 refers to the data table and determines the deviation amount (predetermined parameter to be adjusted) between the frame information and the detected value (S12).

[0092] Next, the parameter adjustment means 87 refers to the data table and determines whether or not the deviation amount exceeds the threshold value (S13). When the parameter adjustment means 87 determines that the deviation amount exceeds the range of the threshold value, it adjusts the deviation amount from the luminance and chrominance of the image data of the partition image to be displayed (S14). Thereafter, the display unit 6 displays a game image including the partition image whose hue, lightness, and saturation have been adjusted (S15). Thereafter, the process proceeds to step S2. On the other hand, in step S13, when the parameter adjustment means 87 determines that the deviation amount does not exceed the range of the threshold value, that is, the deviation amount is within the range of the threshold value, the parameter adjustment means 87 does not adjust the hue, lightness, and saturation of the partition image of the display unit 6. Thereafter, the display unit 6 displays a normal game image (wherein the hue, lightness, and saturation of the partition image are not adjusted) (S1).

[0093] As described above, the foregoing processing method can be created by a program executed by a computer. Such a program is realized by a CPU (Central Processing Unit), a microprocessor, a GPU (Graphic Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like.

[0094] <<Second Embodiment>> Next, a second embodiment of the image display device of the present invention will be described with reference to the accompanying drawings.

[0095] FIG. 11 is a plan view schematically showing an image display device according to the second embodiment of the present invention. Hereinafter, the second embodiment will be described, centering on the differences from the first embodiment described above, and the description of the same matters will be omitted. Note that the same components as those in the first embodiment described above are denoted by the same reference numerals.

[0096] The image display device 100 of the present embodiment is different from the game device 1 of the image display device of the first embodiment in that the operation unit 3 is configured by a touch panel and does not have a reading unit 4. Specifically, as shown in FIG. 11, the image display device 100 of the present embodiment is configured by a smartphone. This image display device 100 includes a display unit 6 having a first area 611A and a second area 611B, a first sub-operation unit 3A corresponding to the first area 611A, and a second sub-operation unit 3B corresponding to the second area 611B. The processing of the image displayed in the first area 611A by the first sub-operation unit 3A and the processing of the image displayed in the second area 611B by the second sub-operation unit 3B can be executed simultaneously.

[0097] The image display device 100 of the present embodiment can display images in the first area 611A and the second area 611B, and can operate the image in the first area 611A with the first sub-operation unit 3A and the image in the second area 611B with the second sub-operation unit 3B. When a predetermined event is triggered, the switching means 84 switches the display area to the entire screen area 61 combining the first area 611A and the second area 611B. At the same time, the partitioning means 85 deletes the partition image. Thus, the image display device 100 of the present embodiment has the same effects as the image display device 1 of the first embodiment.

[0098] Also, in the present embodiment, the visibility of the display images of the respective areas 611A and 611B is improved by adjusting the predetermined parameters so that the partition image displayed in the partition area 612 appears integrally with the outer frame of the display unit 6 (the outer frame of the housing 2). Even though it is a small image display device such as a smartphone, it can give the player an impression that there are two game devices. Note that the parameters do not necessarily need to be adjusted so that the partition image displayed in the partition area 612 appears integrally with the outer frame of the display unit 6 (the housing 2). For example, in order to improve the sense of presence at the time of event occurrence, the hue, brightness, and saturation may be adjusted so as to be more prominent than the respective areas 611A and 611B temporarily.

[0099] In addition, since the image display device 100 of the present embodiment does not have the reading unit 4, the size of the device itself can be reduced. Further, in the image display device 100 of the present embodiment, since the operation unit 3 and the display unit 6 overlap, the size of the device itself can be further reduced. Therefore, the cost required for the device can be reduced.

[0100] Also, in the present embodiment, as shown in FIG. 11, the partition area 612 is a long area connected to the long side of the display unit 6 facing it, but it is not limited to this. For example, it may have various shapes such as a shape in which a part of it is cut out, a divided shape, and the like.

[0101] <<Third Embodiment>> Next, a third embodiment of the image display device of the present invention will be described with reference to the accompanying drawings.

[0102] FIG. 15 is a plan view schematically showing a game device according to the third embodiment of the present invention. FIG. 16 is an enlarged view schematically showing the configuration of the display unit of the game device according to the third embodiment of the present invention. Hereinafter, the third embodiment will be described, focusing on the differences from the first and second embodiments described above, and the description of the same matters will be omitted. Note that the same components as those in the first embodiment described above are denoted by the same reference numerals.

[0103] The game device 1 of the present embodiment, as shown in FIG. 15, does not have the illuminance detection unit S, and the parameter adjustment means 87 adjusts predetermined parameters (hue, lightness, and saturation) of the partition image displayed in the partition area 612 by direct operation input from the user. In this respect, it is different from the game device 1 of the image display device of the first embodiment. Also, in the game device 1 of the present embodiment, the control unit 8 does not include the parameter determination means 86. In the game device 1 of this embodiment, the parameter adjustment means 87 changes and adjusts predetermined parameters (hue, lightness, and saturation) of the partition image in the partition area 612 by receiving an operation input from the user. This parameter adjustment means 87 can change and adjust the predetermined parameters of the partition image in the first partition area 612A or the second partition area 612B for each sub-game device. In this case, the parameter adjustment means 87 can change and adjust the predetermined parameters of the partition images for the upper region, the middle region, and the lower region of the first partition area 612A respectively.

[0104] For example, as shown in FIG. 16, the predetermined parameters of the partition image in the upper region of the first partition area 612A are shown on the display unit 6 of the first sub-game device 1A. Adjacent to each parameter name, a bar representing the degree of the parameter and the current percentage value are displayed. For example, the higher the percentage value of the parameter "saturation", the higher the vividness of the color. The same applies to "hue" and "lightness". Note that the parameter adjustment means 87 can also change and adjust the color parameters of the partition images in the upper region, the middle region, and the lower region collectively. Therefore, also in the game device 1 having such a configuration, the predetermined parameters of the partition image can be adjusted so that the frame body 62 and the partition image appear integrally according to the illuminance around the display unit 6. Therefore, the same operational effects as those of the game device 1 of the first embodiment can be obtained.

[0105] Also, the operation control method of the image display device (game device) of this embodiment is the same as the operation control method of the image display device of the first embodiment described above, except that the process related to the parameter adjustment of the partition image is different. Specifically, the parameter adjustment processing method of the partition image of this embodiment includes: (i) a method of adjusting the predetermined parameters of the partition image by a direct operation input from the user after or while displaying the game image on the display unit 6; and (ii) a method of adjusting the predetermined parameters of the partition image in advance by a direct operation input from the user before displaying the game image on the display unit 6.

[0106] As described above, the image display device and its operation control method according to the present invention have been described based on preferred embodiments, but the present invention is not limited thereto. The configuration of each part can be replaced with any configuration having the same function. Further, any other means or components may be added to the present invention. Further, the present invention may be a combination of any two or more configurations (features) among the above embodiments.

[0107] Note that FIG. 12 is a front view, a plan view, and a bottom view schematically showing the game device according to the first embodiment of the present invention, and FIG. 13 is a rear view and a left side view schematically showing the game device according to the first embodiment of the present invention. The game device is composed of one game device, but can give an impression of being composed of two separate and independent game devices.

Industrial Applicability

[0108] According to the present invention, for example, in an image display device provided with two regions capable of independently displaying images in the display region of the display unit, a predetermined parameter of a part of the image displayed between the regions is adjusted, so that the visibility of the images displayed in the respective regions can be improved. Further, since the predetermined parameter can be adjusted according to the illuminance around the display unit, excellent image display with high visibility can always be performed regardless of the illuminance of the usage environment of the image display device. Furthermore, by adjusting a predetermined parameter of a part of the image, a part of the image and a part outside the display region of the display unit (for example, a frame portion) can be made to look integral, and the visibility of the image displayed in a predetermined region of the display region can also be improved. In this way, an image display device capable of performing image display with excellent visibility corresponding to various image display forms can be provided. Also, a method for controlling the operation of such an image display device can be provided. Therefore, the present invention has industrial applicability.
