Further, if such a state is repeated, there is a risk of causing eye damage. is there. For example, a case where a home video game controller is used and a user plays while watching a video projected on a television is not an exception to this. In particular, when you are enthusiastic about playing, you may not notice that it has become dark, and even if you do, it is difficult to work on self-control to stop playing. Furthermore, the adverse effects on the eyes of children and the like during the development process are alarming, and in particular, playing in darkness can easily induce the attack of photosensitivity, which has recently been regarded as a problem.

[0003]

However, there has been no prior art in which at least the controller or the like is made to take into account the brightness (darkness) of a room or the like using the above controller. The present invention has been made in view of the above problems, and has as its object to provide a controller that takes into consideration the brightness of a room or the like to be used.

[0004]

According to the present invention, there is provided a controller for controlling an image on a display, comprising: a light detecting means for detecting brightness around the controller; and an output signal from the light detecting means. And control means for controlling the operation of the controller (the invention according to claim 1).

Accordingly, the operation of the controller can be appropriately controlled based on the output signal of the light detecting means, and the brightness of a room or the like where the controller is used can be considered. In this case, the control means is configured to interrupt the operation of the controller when the level of the output signal of the light detection means falls below a first predetermined value corresponding to a darkened state. The invention according to (2)), if it becomes dark irrespective of the operator's intention, the controller cannot be forcibly operated, and the effect of the present invention can be reliably achieved. Here, the first predetermined value can be appropriately set to an arbitrary value according to the age of the operator, the operating environment, and the like. In particular, the setting is made so that the operator does not feel dissatisfied with frequent interruptions due to minor changes in the operation environment or the like. The same applies to the following predetermined values. Further, as an aspect of interrupting the operation of the controller, for example, in the case of a video game machine, normally, the progress up to that point is stored in a memory, such as when the game is interrupted halfway, and the state before the interruption is performed when the game is operated again. It is preferable that play can be resumed from the beginning, but the present invention is not limited to this. For example, the power supply of the controller may be completely shut off.

[0006] In this case, the control means may further determine that the level of the output signal of the light detection means falls below the first predetermined value and then exceeds a second predetermined value corresponding to a bright state. If the operation of the controller is restarted from the state before the interruption (the invention according to claim 3), the operation of the controller can be smoothly continued without impairing the effect of the present invention. Here, the second

In this case, the control means is configured to interrupt the operation of the controller when the output of the solar cell falls below a fourth predetermined value corresponding to the darkened state (the invention according to claim 7). Accordingly, the same effect as that of the second aspect can be obtained. Here, the fourth predetermined value can be arbitrarily set as appropriate, and the same applies to other predetermined values described below. In this case, the fourth predetermined value is set to a level at which the controller can be driven stably. However, if the fourth predetermined value does not match the drivable level of the latter, for example, the solar cell Or the configuration is such that, apart from the fourth predetermined value, when the electromotive force of the solar cell falls below a level at which the controller can be driven stably, an alarm to that effect is issued. May be.

[0010] In this case, the control means may further control the operation of the controller when the output of the solar cell exceeds a fifth predetermined value corresponding to a bright state after the output falls below the fourth predetermined value. When configured to resume from the state before the interruption (the invention according to claim 8), claim 3
The same effect as that of the invention can be obtained. Here, the fifth predetermined value may be, for example, the same as the sixth predetermined value described below, and may be set to an arbitrary value as long as it is at least equal to or greater than the fourth predetermined value.

The controller according to the present invention further comprises a second alarm for notifying that the output of the solar cell is lower than a sixth predetermined value corresponding to a slightly darkened state which is larger than the fourth predetermined value. The invention further comprises means (the invention according to claim 9). Thus, the same effect as the fourth aspect of the invention can be obtained. Where the fourth,
The interval between the sixth predetermined values is, for example, between the time when the sixth predetermined value is reached and the time when the operator reaches the first predetermined value, the operator takes some action, switches the feeling, and the like. It can be set appropriately in consideration of giving a margin or the like.

In this case, it is preferable that the second alarm means is at least one of a sound and a display on a display (the invention according to claim 10). Further, the controller according to the present invention is further characterized by further comprising a releasing means capable of releasing the control of the control means (the invention according to claim 11). Thus, when the operation needs to be performed continuously, there is no problem that the operation is interrupted by a change in external brightness.

In this case, a detachable key for fixing the operation of the release means is further provided.
2) For example, by controlling the key of the controller of the video game machine by the parent, it is possible to prevent the inconvenience of the child using the release means without permission. Also,
The controller according to the present invention is characterized in that at least the light detection means and the control means are integrally formed and provided detachably with the controller (the invention according to claim 13).

Accordingly, when the operation is continuously performed in a bright place, it is preferable to remove the light detecting means and the like from the controller by one-touch operation, so that the weight of the controller is reduced. In addition, by making a simple modification to the existing controller, it is possible to attach a light detecting means as a separate component, which is compared with preparing a new controller in which the light detecting means and the like are integrally incorporated. It is cheap.

The control means is for controlling the operation of the controller 10 based on the output signal from the photodiode 22 and is housed inside the case 12. Further, a buzzer 24 is provided below the photodiode 22 as alarm means. The buzzer 24 is for generating a sound when the outside loses a certain level of brightness to warn the operator. Further, the release button 28 as the release means is provided when the photodiode 22 and the buzzer 2
4 is provided. The release button 28 is for releasing the control of the control means as needed.
Details of these control means, alarm means, and cancellation means will be described later. A keyhole 29 is provided at the upper left of the photodiode 22 in FIG. 1 to form a lock mechanism for fixing a release button 28 and preventing the release unit from operating. Reference numeral 26 indicates a start button. The controller 10
Is connected to a power supply for driving the controller 10 by a power cord, or a driving battery is mounted in the controller 10, while it is connected to the TV game machine main body by a connection cord, (Not shown).

FIG. 2 is a schematic block diagram of a circuit constituting the controller 10 and the video game machine main body 33 to which the controller is connected. Like the normal controller, the controller 10 includes an arithmetic unit 30 that processes a signal generated when the cross button 14 or the operation button 16 is pressed.
And calculate and input and display the coordinates on the display,
Alternatively, an interface 32 for transmitting a signal indicating a moving direction of the cursor on the display to the video game machine main body 33 is provided. On the other hand, the video game machine main body 33 has an interface 34 for receiving an instruction signal from the controller 10, an arithmetic unit 36 for processing the signal, an image processing unit 38 for receiving a signal from the arithmetic unit 36 and performing image processing, Interface 39 for sending image control signals to television 41 as a display
Are provided. The image control signal from the video game machine main body 33 is sent to the television 41, and the image is controlled by inputting and displaying coordinates on the screen or moving and displaying a cursor.

The controller 10 is further provided with an operational amplifier 40 for amplifying an output signal from the photodiode 22 and an A / D converter 42 for converting the amplified signal from analog to digital. Conversion unit 42
Is sent to the processing unit 30 for processing,
The buzzer 24 sounds according to predetermined conditions, or the operation of the controller 10 (hereinafter, sometimes referred to as play) is interrupted. The latter mechanism for interrupting the play is normally provided to interrupt the play after storing the progress of the game up to that point in the memory, and the illustration and description thereof are omitted here. These circuits constitute control means for controlling the operation of the controller 10 described above.

On the other hand, a signal generated when the release button 28 is pressed is sent to the arithmetic section 30 and the control of the control means is released. Here, the external brightness and the output signal (output voltage) from the photodiode 22 that changes according to the brightness.
FIG. 3 shows the relationship with the level. The level of the output signal is the output value of the photodiode 22 before being amplified by the operational amplifier 40.

When the external brightness is, for example, 30 lx (lux), the level of the output signal generated by the photoelectromotive force of the photodiode 22, that is, the output voltage is V1 (first predetermined value), and the external brightness is, for example, It is assumed that the output voltage at 110 lx is V2 (second predetermined value), and the output voltage when the external brightness is, for example, 100 lx is V3 (third predetermined value).

Here, the external brightness of 30 lx is considered to be too dark to continue play if the value is less than this value and adversely affect the eyes.
Falls below V1, the operation of the controller 10 is interrupted by the action of the control mechanism receiving this signal. As a mode in which the operation of the controller is interrupted, as described above, the progress up to that point is stored in the memory, and when the operation is performed again, the play can be resumed from the state before the interruption. However, the present invention is not limited to this, and for example, the power supply of the controller 10 may be completely shut down and forcedly terminated. In this case, besides the above-mentioned alarm means for notifying the interruption of the play, if the buzzer 24 issues an alarm for notifying the interruption immediately before the play is actually interrupted, the latter alarm causes the former alarm to be issued. The same effect as the alarm can be obtained, for example, when the change of the external brightness is slow and the play is interrupted after forgetting that the former alarm was issued after a long time elapses from the former alarm. , The interruption was not sudden due to other troubles,
It is preferable that the darkness can be confirmed by the interruption notice.

On the other hand, if the external brightness 110lx exceeds this value, it is considered that a sufficient brightness for continuing the play is secured. Therefore, the external brightness becomes dark and the external brightness becomes 30lx. Lower than one end controller 10
After the operation is interrupted, if the brightness increases again and the external brightness exceeds 110 lx, the output voltage exceeds V2, and the operation of the controller 10 is resumed by the action of the control mechanism receiving this signal, and the start button 26 is pressed. The play is restarted by turning on.

Further, in this case, if the operation of the controller 10 is suddenly interrupted during the play, the operator may feel uncomfortable. Therefore, preferably, a step of giving an alarm prior to the interruption is provided. Allowance is given for taking action or switching feelings. For this reason, the buzzer 24 is sounded to give a warning when the outside becomes gradually dark and becomes lower than the output voltage V3 corresponding to the outside brightness of 100 lx. External brightness 100l at this time
As for x, it is considered that it is troublesome to continue playing for a long time while the value is below this value, but there is no problem if it is short. For example, the output voltage V3 may be equal to V2, or may be set to a desired value as long as it is at least V1. Further, instead of sounding the buzzer 24 or simultaneously with sounding the buzzer 24, a signal is sent from the controller 10 to send a signal to the display via the video game machine main body 33, and, for example, the message "Room becomes dark" May be displayed. "

FIG. 4 shows the operation of the controller 10 described above.
This will be described with reference to the flowchart of FIG. Controller 1
After turning on the power of 0, first, it is determined whether or not the release button 28 is turned on (S1). When the release button 28 is on, the control mechanism for interrupting the play is released, so that the controller 10 is used as usual regardless of the external brightness, the play is performed, and the release button It is determined whether or not 28 is turned on (S1). Therefore, when it is necessary to continuously perform the play, or when it is desired, there is no problem that the play is interrupted by a change in external brightness, which is preferable. On the other hand, when the release button 28 is off, the control mechanism operates to determine the level of the output voltage (S2).

The level of the output voltage is determined (S2). If the output voltage exceeds V2, then it is determined whether or not play is interrupted (S3). When the play is not interrupted, that is, during the play, since the predetermined brightness exceeding 110 lx is continuously secured, it is determined whether the play is continued and the release button 28 is continuously turned on. Is performed (S1). On the other hand, when the play is interrupted, the brightness temporarily increases and exceeds 110 lx after the play is interrupted, and the play can be resumed. Therefore, it is determined whether or not the start button 26 is turned on. When the start button 26 is turned on (S4), the play is resumed (S5), and it is determined whether the release button 28 is turned on (S1). When the start button 26 has not been turned on, the apparatus is in a standby state until the start button 26 is turned on. On the other hand, when the output voltage is equal to or lower than V2, the level of the output voltage is further determined (S6).

The output voltage level is determined (S6). If the output voltage is equal to or higher than V3, the external brightness is 100 lx.
If the brightness is in the range of ~ 110 lx and the brightness is decreasing during play, it has not yet reached the stage of issuing an alarm, while if the brightness is in the process of increasing brightness while play is suspended, the stage until the play is resumed. Therefore, it is determined whether or not the release button 28 is continuously turned on while each state is continued (S1).
On the other hand, when the output voltage is lower than V3, the output voltage level is further determined (S7).

The level of the output voltage is determined (S7). If the output voltage is equal to or higher than V1, then it is determined whether or not play is interrupted (S8). When play is suspended,
After darkening and suspending the play, the brightness is 100lx
However, since the play has not yet been resumed, it is determined whether or not the release button 28 is continuously turned on while continuing the suspended state (S1). . On the other hand, when the play is not interrupted, that is, during the play, since the brightness is insufficient for continuing the play for a long time, the buzzer 24 beeps and an alarm is issued, Is displayed (S9), and it is determined whether or not the release button 28 is turned on (S1).

Further, the level of the output voltage is determined (S
7) If the output voltage is lower than V1, then it is determined whether or not play is interrupted (S10). When the play is suspended, the external brightness is still below 30 lx, and the brightness has not been restored to a level where it becomes darker and the play can be resumed after the play has been interrupted,
While continuing the state in which the play is interrupted, it is determined whether or not the release button 28 is continuously turned on (S).
1). On the other hand, when the play is not interrupted, that is, during the play, the external brightness after the warning is further reduced to a level lower than 30 lx, and it is not preferable to continue the play. Playing is interrupted after sounding 24 to beep and giving a notice of interruption (S11). Then, it is determined whether or not the release button 28 is turned on (S1).

According to the controller 10 according to the first example of the present embodiment, an alarm is issued when the external brightness is insufficient, and when the external brightness is further reduced, the play is forcibly interrupted regardless of the intention of the operator. The operator's eyes are protected. Also,
When the brightness is restored, the play can be resumed from the state before the interruption, which is preferable. In addition, since the release means is provided, there is no problem that the operation is interrupted by a change in external brightness when the operation needs to be performed continuously. Further, since the lock mechanism for fixing the release means is further provided, the parent can manage the key 31 of the controller 10 of the video game machine, thereby preventing the inconvenience of the child from using the release means without permission. .
