Description

[Technical field]

[0001] The present invention relates to a light emitting device and a method for controlling the light emission thereof. [Background technology]

[0002] Recently, there has been a portable light that changes the emitted color to one associated with a swinging motion of the light body in a specific direction in response to a displacement caused by the swinging motion in that direction (see Patent Document 1).

[0003] On the other hand, there is also a rod-shaped light in which the color displayed on the color display button changes each time the color selection buttons are pressed in a specified order, and when the color display button is pressed, the light source unit emits light in the color displayed on the color display button (see Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-4690 A [Patent Document 2] JP 2015-204246 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the case of the portable light in Patent Document 1, the color cannot be changed to the desired color unless a specific swinging motion is performed, and the correspondence between the specific swinging motion and the emitted color must be memorized in order to change the emitted color to the desired color, which is problematic for users, as it makes the light inconvenient for them.

[0006] Furthermore, in the case of the rod-shaped light shown in Patent Document 2, there was a problem that in some cases the color selection button had to be pressed multiple times until the desired color displayed on the color display button was reached, before the light could be emitted in the desired color.

[0007] The present invention has been made in view of the above problems, and has an object to provide a light emitting device which can emit light of a desired color more easily than ever before. [Means for solving the problem]

[0008] In order to solve the above problem, a light-emitting device according to one embodiment of the present invention includes a light-emitting unit, a memory unit that stores information indicating a predetermined order that determines the order in which the light-emitting unit will emit light of multiple colors, a first button that switches between the multiple colors that the light-emitting unit will emit light of in the predetermined order, a setting unit that sets one color from the multiple colors as a recommended color, a second button that accepts input for making the light-emitting unit emit light in the recommended color, and a light-emitting control unit that causes the light-emitting unit to emit light in one of the multiple colors according to a predetermined order in response to a first predetermined input from a user to the first button, and causes the light-emitting unit to emit light in the recommended color regardless of the predetermined order in response to a first predetermined input from the user to the second button.

[0009] In order to solve the above problem, a light-emitting control method according to one embodiment of the present invention is a light-emitting control method for a light-emitting device including a light-emitting unit, a memory unit that stores information indicating a predetermined order that determines the order in which the light-emitting unit emits light of multiple colors, a first button, and a second button, and includes a setting step of setting one color from the multiple colors as a recommended color, a first light-emitting control step of causing the light-emitting unit to emit light in one of the multiple colors according to a predetermined order in response to a first predetermined input from a user to the first button, and a second light-emitting control step of causing the light-emitting unit to emit light in the recommended color regardless of the predetermined order in response to a first predetermined input from the user to the second button.

[0010] In the above device, a third button may be provided for switching between the multiple colors that the light-emitting unit emits in a reverse order to a predetermined order, and the light-emitting control unit may be configured to cause the light-emitting unit to emit one of the multiple colors in a reverse order to the predetermined order in response to a first predetermined input from the user to the second button.

[0011] In the above device, the setting unit may further set a light-emitting pattern indicating a light-emitting sequence desired by the user from among the plurality of colors, the memory unit may further store information indicating the light-emitting pattern, and the light-emitting device may further include a selection unit which selects either the light-emitting pattern or a predetermined sequence, and the light-emitting control unit may cause the light-emitting unit to emit light in one of the plurality of colors in accordance with an input from the user to the first button or a first predetermined input from the user to the second button, in accordance with either the light-emitting sequence indicated by the light-emitting pattern selected in the selection unit or the predetermined sequence.

[0012] In the above device, the memory unit stores information indicating the light emitting colors indicating each of the light emitting patterns and the predetermined sequence, and the selection unit, when the light emitting unit is not emitting light and a second predetermined input is made to the third button or to both the first button and the third button, starts selecting the light emitting sequence from the light emitting sequence indicated by the light emitting pattern or the light emitting sequence indicated by the predetermined sequence, and the light emitting control unit, during the selection of the light emitting sequence, causes the light emitting unit to emit a light emitting color indicating either the light emitting pattern or the predetermined sequence, and switches the light emitting color indicating either the light emitting pattern or the predetermined sequence in accordance with the user's input to the first button, and when a second predetermined input is made by the user to the first button or the third button during the selection of the light emitting sequence, selects the light emitting pattern or the predetermined sequence corresponding to the light emitting color being emitted by the light emitting unit at that time as the light emitting sequence for light emitting control.

[0013] In the above device, the selection unit may, during selection of the light emission order, delete from the memory unit the light emission pattern corresponding to the light emission color currently being emitted by the light-emitting unit in accordance with a second specified input to both the first button and the third button.

[0014] In the above device, when the light-emitting device is not emitting light and a second predetermined input is received to the third button or to both the first button and the third button, the setting unit starts setting a light-emitting pattern, and while the light-emitting pattern is being set, the setting unit stores the light-emitting color that is making the light-emitting unit emit light as one of the light-emitting colors of the light-emitting pattern in accordance with the first predetermined input from the user to the first button, and while the light-emitting pattern is being set, the light-emitting control unit switches the light-emitting color that is making the light-emitting unit emit light in accordance with the first predetermined input from the user to the third button, and while the light-emitting pattern is being set, the setting unit stores in the memory unit a light-emitting pattern in which the light-emitting colors stored up to that point are stored in the order in which they are stored as the light-emitting order in accordance with the second predetermined input from the user to the first button or the third button.

[0015] In the above-mentioned device, the light emitting device may be a rod-shaped light. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, a light emitting device according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0019] <Embodiment> <Configuration> Fig. 1 is an external view showing the external appearance of a light emitting device 100. As shown in Fig. 1, the light emitting device 100 is, for example, a rod-shaped light, but the shape of the light emitting device 100 is not limited to a rod shape.

[0020] As shown in FIG. 1, the light emitting device 100 includes a light emitting section 120 and a gripping section 140 connected via a connecting section 130.

[0021] The light emitting unit 120 has a function of emitting light. The light emitting unit 120 may emit light by itself, or may have a light emitting body provided in the connection portion 130, and light projected from the light emitting body passes through the light emitting unit 120 to emit light. The light emitting unit 120 may have a configuration in which, for example, a decorative sheet that transmits and diffuses light is provided inside a cylindrical transparent plastic, and light from a light emitting body that emits light in various colors provided in the connection portion 130 is diffused and projected to the surroundings. The light emitting body may be a light emitting diode or an LED. Alternatively, the light emitting unit 120 may be realized by a configuration in which an LED sheet is provided inside a cylindrical transparent resin with its light emitting surface facing the outside.

[0022] The connecting unit 130 is a connecting member that connects the light-emitting unit 120 and the gripping unit 140. The connecting unit 130 may be configured to connect the light-emitting unit 120 and the gripping unit by, for example, a screw structure or a locking member. As a method for connecting the light-emitting unit 120 and the gripping unit 140, various conventional methods may be used.

[0023] The grip part 140 is a member with which a user grips the light emitting device 100. The grip part 140 may have any form as long as it is configured to enable a user to grip the light emitting device 100. The grip part 140 may be molded integrally with the connection part 130.

[0024] The gripping part 140 includes a first button 111, a second button 112, and a third button 113. The first button 111, the second button 112, and the third button 113 are made of, for example, resin such as plastic, and are configured to be depressible. Although not shown in FIG. 1, the first button 111, the second button 112, and the third button 113 each receive operations related to the emission of light from the light-emitting device 100 and the control of the emission of light. Here, each button is described as a push-type button, but this is not limited thereto, and each button may have a function of receiving an input from a user. For example, each button may be realized by a touch sensor.

[0025] The gripping part 140 has therein a power supply (not shown) for operating the light emitting device 100. The gripping part 140 is configured so that the power supply can be removed, and the power supply can be inserted or removed by removing the power supply cover 150. The power supply cover 150 is configured so that it can be freely attached to the gripping part 140. The power supply cover 150 may be attached to the gripping part 140 in any manner, and may be attached to the gripping part 140 by a screw, or may be engaged by a claw-shaped member, for example.

[0026] Fig. 2 is a block diagram showing an example of the configuration of light emitting device 100. As shown in Fig. 2, light emitting device 100 includes a first button 111, a second button 112, a third button 113, a light emitting unit 120, a light emission control unit 121, a setting unit 122, a selection unit 123, and a storage unit 124.

[0027] The first button 111 is a button that can be pressed by the user. The first button 111 is a button that can detect both a short press (a press that does not continue for a predetermined period of time or more) and a long press (a press that continues for a predetermined period of time or more).

[0028] The second button 112 is a button that can be pressed by the user. The second button 112 is a button that can detect both a short press (a press that does not continue for a predetermined period of time or more) and a long press (a press that continues for a predetermined period of time or more).

[0029] The third button 113 is a button that can be pressed by the user. The third button 113 is a button that can detect both a short press (a press that does not continue for a predetermined period of time or more) and a long press (a press that continues for a predetermined period of time or more).

[0030] The light emitting unit 120 emits light in a specified color from among a plurality of colors. The light emitting unit 120 is realized by, for example, a light emitting diode or an LED. The light emitting unit 120 emits light according to an instruction from a light emission control unit 121.

[0031] The light emission control unit 121 has a function of controlling the light emission of the light emitting unit 120. The light emission control unit 121 has a function of performing light emission processing of the light emitting unit 120 according to the pressing contents of the first button 111, the short pressing or long pressing of the second button 112, and the short pressing or long pressing of the third button 113 in various situations such as when the light emitting unit 120 is emitting light, when it is not emitting light, when a light emission pattern is being set, and when a light emission pattern is being selected. When the light emitting unit 120 is being caused to emit light, the light emission control unit 121 detects pressing of the second button 112 regardless of the selected light emission pattern, and causes the light emitting unit 120 to emit light in a recommended color set in the storage unit 124 by the setting unit 122. Details of the light emission processing by the light emission control unit 121 will be described later with reference to the flowcharts shown in FIG. 4 to FIG. 6.

[0032] Setting unit 122 has a function of setting a light emission pattern. When detecting a long press of first button 111 or both first button 111 and third button 113, setting unit 122 executes a light emission pattern setting process. Details of the light emission pattern setting process performed by setting unit 122 will be described later with reference to the flowchart shown in FIG.

[0033] Furthermore, the setting unit 122 has a function of setting a recommended color for emitting light in a color desired by the user regardless of the order of the light emission patterns while the light-emitting unit 120 is emitting light. When the setting unit 122 detects that the second button 112 has been pressed and held by the user while the light-emitting unit 120 is emitting light, the setting unit 122 stores in the memory unit 124 the light emission color emitted by the light-emitting unit 120 at that time as a recommended color.

[0034] Selection unit 123 has a function of selecting an illumination pattern to be used from the illumination patterns stored in storage unit 124. Selection unit 123 executes an illumination pattern selection process when it detects a long press of first button 111 or a long press of both first button 111 and third button 113. Details of the illumination pattern selection process performed by selection unit 123 will be described later with reference to the flowchart shown in FIG.

[0035] Each of the light emission control unit 121, the setting unit 122, and the selection unit 123 is realized by a processor, and the above-mentioned light emission control, setting process, and selection process are realized by the processor executing a program stored in the storage unit 124. Note that the light emission control unit 121, the setting unit 122, and the selection unit 123 may be realized by one processor or multiple processors.

[0036] The storage unit 124 is a storage medium having a function of storing various programs and data required for the operation of the light emitting device 100. The storage unit 124 is realized by, for example, an HDD, an SSD, a flash memory, a RAM, a ROM, etc. The storage unit 124 stores programs such as a light emission control program related to light emission control, a setting program related to setting a light emission pattern, and a selection program related to selecting a light emission pattern, as well as light emission pattern information 300 indicating the set light emission pattern, and a light emission color set as a recommended color. The light emitting device 100 has the above configuration.

[0037] <Data> FIG. 3 is a conceptual data diagram showing an example of the data structure of light emission pattern information 300 stored in the storage unit 124 of the light emitting device 100. As shown in FIG.

[0038] 3, the light emission pattern information 300 is information in which a pattern name 301 is associated with a light emission sequence 302. The light emission pattern information 300 is information that specifies the light emission color to be emitted by the light emitting unit 120 of the light emitting device 100.

[0039] Pattern name 301 is identification information that enables light emitting device 100 to uniquely identify a light emitting pattern. Here, pattern name 301 is shown as a name for ease of understanding, but pattern name 301 may be expressed as a number, a symbol, or the like as long as it can be distinguished from other light emitting patterns.

[0040] The light emission sequence 302 is information indicating the order of light emission colors for the light emitting unit 120 to emit light. The light emission sequence 302 indicates a number indicating the order of light emission and a color associated with the number. For example, in the case of a default pattern, which is one of the light emission patterns, the light emission device 100 emits light in the forward order of "red, navy blue, white, orange, green, purple, pink, ...". When emitting light in the forward order, the light emission device 100 emits light in the above-mentioned order in the case of the default pattern, and when emitting light in the reverse order, the light emission device 100 emits light in the order of "red, pink, purple, green, orange, white, navy blue, red, ..." since the default pattern does not set colors after pink. In addition, colors may not be set for numbers as the light emission sequence, and in that case, in the example of FIG. 3, it is indicated by "-". In this light emission sequence, the first color, which is the color No. 1, and the last color in the light emission sequence are looped. That is, as shown in FIG. 8, in the case of memory pattern 1, which is one of the light emission patterns, each time the first button 111 is pressed briefly while the light-emitting unit 120 is emitting light, the light color is changed in the following order: "white, green, blue, white, green, blue, white, ...".

[0041] The identification color 303 is information indicating a light emission color uniquely associated with each light emission pattern so that the user can recognize which light emission pattern he or she is about to select when selecting a light emission pattern. That is, when selecting a light emission pattern, for example, if red light is emitted, this indicates that memory turn 1 is in the selected state.

[0042] <Operation> Now, a description will be given of the operation of the light emitting device 100. Fig. 4 is a main flowchart showing an example of the operation of the light emitting device 100. The flowchart shown in Fig. 4 shows a process that starts from a state in which the light emitting device 100 is not emitting light.

[0043] Light emitting device 100 determines whether there is an input to at least one of first button 111, second button 112, and third button 113 depending on whether any of the buttons has been pressed by the user (step S401). If there is an input (YES in step S401), the process proceeds to step S402, and if there is no input (NO in step S401), the process waits until there is an input.

[0044] If the input is a long press of the first button 111 (YES in step S402), the light emission control unit 121 starts a light emission control process shown in step S403. Details of the light emission control process will be described later. When the light emission control unit 121 ends the light emission control process, the process returns to step S401.

[0045] If the input is not a long press of first button 111 (NO in step S402) but a long press of both first button 111 and third button 113 (YES in step S404), setting unit 122 or selection unit 123 starts a lighting pattern setting / selection process shown in step S406. Details of the lighting pattern setting / selection process will be described later. When the lighting pattern setting / selection process ends, the process returns to step S401.

[0046] Even if the input is not a long press of both the first button 111 and the third button 113 (NO in step S404), if the input is a long press of the third button 113 (YES in step S405), the setting unit 122 or the selection unit 123 starts the setting / selection process of the light emission pattern.

[0047] In other cases (NO in step S405), the input is not for performing any operation, so the process returns to step S401.

[0048] The above is an explanation of the main flowchart of the operation of the light emitting device 100.

[0049] Now, the light emission control process included in the main flow chart will be described.

[0050] FIG. 5 is a sub-flowchart showing details of the light emission control process indicated in step S403 in the main flow chart of FIG.

[0051] 5, in response to a long press of first button 111 of light-emitting device 100, light-emitting control unit 121 identifies the selected light-emitting pattern from information related to the selected light-emitting pattern stored in storage unit 124. Then, light-emitting control unit 121 causes light-emitting unit 120 to emit light in the leading color (the first light-emitting color in the light-emitting order) of the identified light-emitting pattern (step S501).

[0052] The setting unit 122 determines whether the second button 112 has been pressed and held down based on whether the second button 112 has been pressed down for a predetermined time (e.g., 3 seconds) or more (step S502). If the second button 112 has been pressed and held down (YES in step S502), the setting unit 122 sets the color of light emitted by the light-emitting unit 120 at that time as the recommended color in the storage unit 124 (step S503), and returns to step S502.

[0053] If the second button 112 has not been pressed long (NO in step S502), the light emission control unit 121 determines whether the first button 111 has been pressed shortly based on whether the first button 111 has been pressed and the pressing time has not exceeded a predetermined time (step S504). If the first button 111 has been pressed shortly (YES in step S504), the light emission control unit 121 switches the light color of the light emitting unit 120 to the next light color indicated in the light emission order of the selected light emission pattern (step S505), and returns to step S502.

[0054] If the first button 111 has not been pressed briefly (NO in step S504), the light emission control unit 121 determines whether or not the third button 113 has been pressed briefly (step S506). If the third button 113 has been pressed briefly (YES in step S506), the light emission control unit 121 switches the light color of the light emitting unit 120 to the next color in the reverse light emission order of the selected light emission pattern (the previous color in the forward direction) (step S507), and returns to step S502.

[0055] If the third button 113 has not been pressed briefly (NO in step S506), the light emission control unit 121 determines whether or not the second button 112 has been pressed briefly (step S508). If the second button 112 has been pressed briefly (YES in step S508), the light emission unit 120 is caused to emit light in the emission color set as the recommended color in the storage unit 124, and the process returns to step S502.

[0056] If the second button 112 has not been pressed briefly (NO in step S508), the light emission control unit 121 determines whether or not the first button 111 has been pressed and held (step S510). If the first button 111 has not been pressed and held (NO in step S510), the process returns to step S502, and if the first button 111 has been pressed and held (YES in step S510), the light emission control unit 121 stops the light emission by the light emission unit 120 (step S511) and ends the light emission control process.

[0057] The above is the process related to the light emission control of the light emitting device 100.

[0058] Finally, the operation of the setting and selection processing of the light emission pattern will be described with reference to Fig. 6, which is a sub-flowchart showing details of the light emission pattern setting / selection processing in step S406 in the main flow chart of Fig. 4.

[0059] When the process of setting / selecting the light emission pattern is started, the light emission control unit 121 causes the light emission unit 120 to flash in the light color associated with the pressed button (long press of the third button 113 (see FIG. 4, step S404), or long press of both the first button 111 and the third button 113 (see FIG. 4, step S405)) (step S601).

[0060] The selection unit 123 determines whether or not the second button 112 has been pressed briefly (step S602).

[0061] When the second button 112 is pressed briefly (YES in step S602), the selection unit 123 changes the selected illumination pattern to another illumination pattern. In response to the change, the illumination control unit 121 causes the illumination unit 120 to emit light in a color corresponding to the changed illumination pattern.

[0062] The selection unit 123 determines whether or not either the first button 111 or the third button 113 has been pressed and held (step S604).

[0063] If either the first button 111 or the third button 113 is pressed and held (YES in step S604), the illumination pattern corresponding to the illumination color emitted by the light-emitting unit 120 at that time is registered in the memory unit 124 as the selected illumination pattern (illumination pattern to be used) (step S605), and the processing ends.

[0064] If neither the first button 111 nor the third button 113 has been pressed long (NO in step S604), the setting unit 122 judges whether or not both the first button 111 and the third button 113 have been pressed long (step S606). If neither the first button 111 nor the third button 113 have been pressed long (NO in step S606), the process returns to step S602, and if both the first button 111 and the third button 113 have been pressed long (YES in step S606), the process deletes information on the light emission order of the light emission pattern corresponding to the light emission color emitted by the light-emitting unit 120 at that time from the light emission pattern information 300 in the storage unit 124 (step S607), and ends the process.

[0065] In step S602, if the second button has not been pressed briefly (NO in step S602), setting of the light emission pattern is started based on any one of the inputs of a short press of the first button, a short press of the third button, and a long press of the third button.

[0066] First, the light emission control unit 121 determines whether or not the third button 113 has been pressed briefly (step S608). If the third button 113 has been pressed briefly (YES in step S608), the light emission control unit 121 switches the light emission color emitted by the light emitting unit 120 according to the light emission order indicated by the default pattern of the light emission pattern information 300 (step S609), and returns to step S608.

[0067] If the third button 113 has not been short-pressed (step S608), the setting unit 122 determines whether or not the first button 111 has been short-pressed (step S610). If the first button 111 has been short-pressed (YES in step S610), the setting unit 122 stores the luminous color emitted by the light-emitting unit 120 in the storage unit 124 as the next luminous color in the luminous pattern (step S611), and returns to step 608.

[0068] If first button 111 has not been pressed briefly (NO in step S610), setting unit 122 determines whether or not third button 113 has been pressed for a long time (step S612).

[0069] If third button 113 is pressed and held (step S612), a new light emission pattern is registered in light emission pattern information 300 (step S613) in which the light emission colors registered in step S611 are lit in the same order as the registered order, and the process ends. If third button 113 is not pressed and held (NO in step S612), the process returns to step S608.

[0070] <Summary> According to the light emitting device 100, when the light emitting unit 120 emits light in a desired color, the user can register the color as a recommended color by simply pressing the second button 112 for a long time. After that, the light emitting unit 120 can emit light in the recommended color at any time at a timing desired by the user, regardless of the light emission sequence of the light emitting pattern being used, by simply pressing the second button 112 for a short time. In addition, the light emitting device 100 can easily re-register a new recommended color by simply pressing the second button 112 for a long time when the light emitting unit 120 emits light in a desired color. Furthermore, the light emitting device 100 can realize many functions with a small number of inputs (number of buttons), such as setting a light emitting pattern that emits light in a sequence desired by the user, switching the light emitting color in the light emitting pattern, and freely selecting the light emitting pattern to be used by registering multiple light emitting patterns.

[0071] <Supplementary Information> The device according to the above embodiment is not limited to the above embodiment, and may be realized by other methods. Various modifications will be described below.

[0072] (1) Although not specifically shown in the above embodiment, the light emission control unit 121 of the light emitting device 100 may cause the light emitting unit 120 to emit light in various modes, such as constant emission, gradation emission, blinking emission, etc. In this case, the light emitting device 100 may be configured to change the emission mode by pressing a combination of three buttons, etc.

[0073] (2) Although not specifically shown in the above embodiment, when first button 111 or third button 113 is pressed while emitting light in a recommended color, light emission control unit 121 may be configured to return to emitting light of the color before the recommended color.

[0074] (3) In the above embodiment, two types of inputs, a short press and a long press, are presented for each button (first button 111, second button 112, third button 113), but this is not limited to this. For example, two presses within a predetermined time may be detected, and the two presses may be used as a trigger to trigger any of the above-mentioned processes. Also, the short press and the long press shown in the above embodiment may be interchanged to achieve the same operation. That is, the above-mentioned first predetermined input may be a short press and the second predetermined input a long press, or the first predetermined input may be a long press and the second predetermined input a short press.

[0075] (4) In the above embodiment, an example in which only one color is set as the recommended color has been described, but the recommended color is not limited to one color. Any number of recommended colors may be set.

[0076] To achieve this configuration, the light emitting device 100 may be configured to include a second and a third second button 112. The second recommended color is set by pressing and holding the second second button 112, and the third recommended color is set by pressing and holding the third second button 112. The light emitting unit 120 may be configured to emit the associated recommended color in response to a short press of each of the pressed second buttons 112.

[0077] Alternatively, the second button 112 and the first button 111 may be pressed and held simultaneously to set the second recommended color, and the second button 112 and the third button 113 may be pressed and held simultaneously to set the third recommended color. Then, the light-emitting unit 120 may be made to emit light in the second recommended color by pressing the first button 111 and the second button 112 briefly simultaneously, and the light-emitting unit 120 may be made to emit light in the third recommended color by pressing the second button 112 and the third button 113 briefly simultaneously.

[0078] (5) In the above embodiment, the recommended color in the light emitting device is set by the processor of the device executing a light emission control program or the like, but this may be realized by a logic circuit (hardware) or a dedicated circuit formed in an integrated circuit (IC (Integrated Circuit) chip, LSI (Large Scale Integration)) or the like in the device. Furthermore, these circuits may be realized by one or more integrated circuits, and the functions of the multiple functional units shown in the above embodiment may be realized by one integrated circuit. LSIs are sometimes called VLSIs, super LSIs, ultra LSIs, etc., depending on the degree of integration.

[0079] The light-emission control program may be recorded on a processor-readable recording medium, and the recording medium may be a "non-transitory tangible medium," such as a tape, a disk, a card, a semiconductor memory, or a programmable logic circuit. The light-emission control program may be supplied to the processor via any transmission medium (such as a communication network or a broadcast wave) capable of transmitting the light-emission control program. The present invention may also be realized in the form of a data signal embedded in a carrier wave, in which the light-emission control program is embodied by electronic transmission.

[0080] The light emission control program can be implemented using, for example, a script language such as Action Script or JavaScript (registered trademark), an object-oriented programming language such as Objective-C or Java (registered trademark), or a markup language such as HTML5.

[0081] (6) The configurations described in the above embodiment and the configurations described in the supplementary notes may be implemented in appropriate combinations. [Explanation of symbols]
