BACKGROUND OF THE INVENTION
The present invention relates to a screen saver control device, and more particularly to a screen saver control device that controls a screen saver execution waiting time. The present invention also relates to a recording medium storing a program for causing a computer to perform such processing in the screen saver control device.
[0002]
[Prior art]
When a display unit such as a display used in a computer apparatus displays the same screen for a long time, a trace of the same screen may remain even if the display unit is turned off. This phenomenon is called “burn-in”. In order to prevent the display unit from being burned in, the computer device has a screen saver function that automatically darkens the screen or continuously moves the graphic on the screen when no operation signal is input to the computer device for a certain period of time.
[0003]
Currently, the screen saver function is often provided in an operating system used for a computer device. This screen saver function is displayed when an operation signal is not input from the input unit of the computer device, such as a keyboard or a mouse, during the screen saver execution wait time by setting the screen saver execution wait time on the operating system. The screen of the unit is switched from the processing corresponding screen corresponding to the processing in the computer device to the screen saver screen.
[0004]
The screen saver function immediately switches the screen of the display unit from the screen saver screen to the processing-compatible screen when an operation signal is input to the input unit of the computer device while the screen of the display unit is switched to the screen saver screen. Such a screen saver function is an important function for preventing screen burn-in.
[0005]
[Problems to be solved by the invention]
However, conventionally, the screen saver function needs to set a screen saver execution waiting time in advance on the operating system. For example, when a program is being developed and the think time is long and the input of operation signals to the computer device is small, the screen saver execution waiting time that has been set in advance has elapsed and the screen saver function is not required. There was a problem of switching from the processing support screen to the screen saver screen.
[0006]
In this case, the user of the computer apparatus has to input an operation signal to the input unit in order to switch the screen of the display unit from the screen saver screen to the processing-compatible screen, resulting in a decrease in work efficiency. .
The present invention has been made in view of the above points, and a first object of the present invention is to provide a screen saver control device capable of variably controlling the waiting time until the screen saver is executed in accordance with the user's work state. That is.
[0007]
A second object of the present invention is to provide a recording medium storing a program for causing a computer to perform the processing in such a screen saver control device.
[0008]
[Means for Solving the Problems]
Therefore, in order to solve the first problem, the present invention is set in a state in which a processing corresponding screen corresponding to processing in a computer device is displayed on a display unit, as described in claim 1. When an operation signal is not input to the computer device during a screen saver execution waiting time, the display unit screen is switched from a processing-compatible screen to a screen saver screen, and then the display unit is input when the operation signal is input to the computer device. In the screen saver control device that restores the screen from the screen saver screen to the processing-compatible screen, the time saver that measures the time during which the screen saver screen is maintained, and the screen saver based on the time measured by the time measurer A waiting time control means for controlling the execution waiting time of Configured so that.
[0009]
In such a screen saver control device, when an operation signal is not input to the computer device during the set screen saver execution waiting time while the processing-compatible screen is displayed on the display unit, the screen of the display unit is changed from the display-compatible screen to the screen saver. Switch to the screen. Thereafter, when the user performs some operation requiring the processing-compatible screen and an operation signal based on the operation is input to the computer apparatus, the screen of the display unit is restored from the screen saver screen to the processing-compatible screen.
[0010]
At this time, the time during which the screen saver screen is maintained (the screen saver screen maintenance time) is measured. The screen saver execution waiting time is changed based on the measured screen saver screen maintenance time. As described above, if the operation signal is not input to the computer device after the screen of the display unit is restored to the processing-compatible screen and the screen saver execution time is changed, the screen is again switched from the processing-compatible screen to the screen saver screen. .
[0011]
The time from when the screen saver screen is switched to when the operation signal based on the user's operation is input to the computer device is the screen saver screen maintenance time. If the maintenance time of the screen saver screen is extremely short, it can be considered that the user originally did not need the screen saver screen and wanted to continue the operation while viewing the processing corresponding screen. On the other hand, when the maintenance time of the screen saver screen is long, it can be considered that the user's work while viewing the processing-compatible screen is small.
[0012]
Thus, the maintenance time of the screen saver screen reflects the work status of the user using the computer device. Therefore, by controlling the screen saver execution waiting time based on the maintenance time of the screen saver screen, the screen saver execution waiting time reflects the work state of the user.
When it can be considered that the user originally did not need the screen saver screen, from the viewpoint of increasing the display time of the processing compatible screen as much as possible, the present invention provides the screen saver control device as described in claim 2 The waiting time control means may comprise waiting time extension means for increasing the waiting time for executing the screen saver when the measured time is shorter than a predetermined first reference time.
[0013]
According to such a screen saver control device, when the measured time (screen saver screen maintenance time) is shorter than the first reference time, the screen saver execution waiting time is lengthened. As a result, the display time of the process corresponding screen becomes longer. The first reference time is determined based on a maintenance time (slight maintenance time) of the screen saver screen that can be considered that the user did not need the screen saver screen.
[0014]
On the other hand, when the user is not working, it is desirable to switch to the screen saver screen as much as possible from the viewpoint of preventing the burn-in of the display unit. In the case where it can be considered that there is little work while looking at the user's processing-corresponding screen, from the viewpoint of enabling switching to the screen saver screen as soon as possible, the present invention provides, as described in claim 3, In each of the screen saver control devices, the waiting time control means includes a waiting time shortening means for shortening the waiting time for executing the screen saver when the measured time is longer than a predetermined second reference time. can do.
[0015]
In such a screen saver control device, when the maintenance time of the measured screen saver screen is longer than the second reference time, the screen saver execution waiting time is shortened. As a result, when the operation signal is not input to the computer device, the screen saver screen is switched relatively quickly. The second reference time is appropriately determined as a time longer than the maintenance time of the screen saver screen that can be considered that the user did not need the screen saver screen.
[0016]
From the viewpoint of simply configuring a time measuring means for measuring the maintenance time of the screen saver screen using a clock function provided in the computer device, the present invention provides the screen saver control device according to claim 4, The time measuring means acquires a first time obtaining means for obtaining a first time when the process corresponding screen is switched to a screen saver screen, and a second time obtaining a second time when the screen saver screen is returned to the process corresponding screen. Time acquisition means, and time calculation means for calculating the time that the screen saver screen was maintained from the first and second times acquired by the first time acquisition means and the second time acquisition means, respectively. It can comprise so that it may be provided.
[0017]
According to such a screen saver control device, the maintenance time of the screen saver screen is measured by the clock function provided in the computer device from the beginning. As a result, the time measuring means is easily configured.
Further, in order to solve the second problem, the present invention is set in a state in which a processing corresponding screen corresponding to processing in a computer device is displayed on a display unit, as described in claim 5. When an operation signal is not input to the computer device during a screen saver execution waiting time, the display unit screen is switched from a processing-compatible screen to a screen saver screen, and then the display unit is input when the operation signal is input to the computer device. Measuring the time during which the screen saver screen is maintained in a recording medium storing a program for causing the computer device to perform the processing in the screen saver control device that returns the screen from the screen saver screen to the processing-compatible screen. Based on the timing procedure and the time measured in the timing procedure. There are configured to store a program and a wait time control step of controlling the execution waiting time of the screen saver.
[0018]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a hardware configuration diagram of a computer device that realizes a screen saver control device according to an embodiment of the present invention.
A screen saver is a function that prevents the display unit from burning after the same screen is displayed on a display unit such as a display used in a computer device for a long time, even if the display unit is turned off. is there.
[0020]
The screen saver function sets a screen saver execution waiting time in advance, and automatically darkens the screen or intermittently displays a predetermined graphic if there is no input to the computer device during the screen saver execution waiting time. The display unit is prevented from being burned by switching to a screen saver screen that can be moved up.
[0021]
In FIG. 1, the computer apparatus 10 includes an input unit 20, a display unit 30, a drive unit 40, a recording medium 50, an auxiliary storage unit 60, a memory unit 70, which are mutually connected by a bus B. And an arithmetic processing unit 80.
The input unit 20 includes a keyboard and a mouse that are operated by a user of the computer apparatus 10, and is used to input various operation signals to the computer apparatus 10.
[0022]
The display unit 30 displays various windows, data, and the like necessary for operating the computer device 10 during the processing-compatible screen, and displays a screen saver screen when there is no input operation on the computer device 10 for a predetermined time.
A program related to the screen saver control device is provided by a recording medium 50 such as a CD-ROM, for example. The recording medium 50 storing the program related to the screen saver control device is set in the drive unit 40, and the program is installed in the auxiliary storage unit 60 from the recording medium 50 via the drive unit 40.
[0023]
The auxiliary storage unit 60 stores a program related to the installed screen saver control device, and stores necessary files, data, graphic data of the screen saver, and the like.
The memory unit 70 reads and stores a program related to the screen saver control device from the auxiliary storage unit 60 when the computer device 10 is activated.
[0024]
The arithmetic processing unit 80 executes processing related to the screen saver control device in accordance with a program related to the screen saver control device read and stored in the memory unit 70.
The program related to the screen saver control device includes a screen saver start time when the user of the computer device 10 does not input operation data from the input unit 20 during the screen saver execution waiting time, and the screen corresponding to the screen saver screen is switched from the process corresponding screen. Thereafter, the user of the computer device 10 inputs operation data from the input unit 20, and the screen saver release time when the screen saver screen is switched to the processing-compatible screen is supplied from the operating system or hardware.
[0025]
Based on the time when the processing-compatible screen is switched to the screen-saver screen and the time when the screen-saver screen is switched to the processing-compatible screen, the maintenance time of the screen saver screen is measured. The working state of the user is determined.
For example, if the maintenance time of the screen saver screen is extremely short, the user is working while looking at the processing support screen, and in order to continue working while looking at the processing support screen, the user can input an operation signal and process from the screen saver screen. It can be regarded as having returned to the screen. In short, it can be considered that the user did not need the screen saver, and the execution waiting time of the screen saver is set to be long. On the other hand, when the maintenance time of the screen saver screen is long, it can be considered that there is little work to be performed while looking at the processing corresponding screen of the user. In short, the screen-saver execution waiting time is set short in order to switch from the processing-compatible screen to the screen saver to prevent the display unit 30 from burning.
[0026]
As described above, it is determined whether the user of the computer apparatus 10 needs the screen saver function, and the screen saver execution waiting time is appropriately set.
The processing of the screen saver control device for setting the screen saver execution waiting time is, for example, a program related to the screen saver control device installed in the auxiliary storage unit 60 is read into the memory unit 70, and the procedure shown in FIG. Executed according to
[0027]
In FIG. 2, if no operation data is input from the input unit 20 during the screen saver execution waiting time, the arithmetic processing unit 80 switches the display unit 30 from the process corresponding screen to the screen saver screen, and is supplied from the hardware or operating system. The time t1 when the screen saver is started is stored in the memory unit 70 (S1).
[0028]
When the operation data is input from the input unit 20 of the computer device 10 after the screen saver is started, the arithmetic processing unit 80 switches the display unit 30 from the screen saver screen to the processing corresponding screen, and is supplied from the hardware or the operating system. The time t2 when the screen saver is released is stored in the memory 70 (S2).
[0029]
Subsequently, the arithmetic processing unit 80 reads the time t1 when the screen saver is started and the time t2 when the screen saver is released from the memory unit 70, and calculates the maintenance time t of the screen saver screen by the following equation (1). (S3)
t = t2-t1 (1)
Next, the state of the flag F indicating whether or not to use the function of making the screen saver execution waiting time variable is determined (S4). This flag F is set when, for example, various system conditions are set. For example, the flag F is set to “1” when the function is used, and the flag F is set to “0” when the function is not used.
[0030]
If it is determined that the flag F is set to “1” (YES in S4), the screen saver screen maintenance time t (= t2−t1) calculated as described above is longer than a predetermined time b. It is determined whether or not (S5). The predetermined time b is determined from the following viewpoint.
When a user is working using a computer device, the user may be examining the display contents without performing any particular operation while looking at the processing-compatible screen. Even in such a case, when the screen saver execution waiting time elapses, the process corresponding screen is switched to the screen saver screen. At that time, since the user is working, the user performs an appropriate input operation (such as a mouse operation) in order to immediately return from the switched screen saver screen to the processing-compatible screen.
[0031]
As described above, when the screen returns to the processing-compatible screen in a short time after switching to the screen saver screen, the user can determine that the screen saver is not originally required. From this, the predetermined time b is a time (screen saver screen maintenance time) from when the user switches to a screen saver screen that can be regarded as not requiring a screen saver to return to the processing-compatible screen, for example, 1 second. Set to degree.
[0032]
When it is determined that the screen saver maintenance time t calculated as described above is shorter than the predetermined time b (NO in S5), it is assumed that the user does not want to switch to the screen saver screen, and the following equation (2) Thus, the waiting time W of the screen saver is increased by a time a (for example, 300 seconds) (S7).
W = W + a (2)
On the other hand, when it is determined that the maintenance time t of the screen saver screen is longer than the predetermined time b (YES in S5), it is further determined whether or not the maintenance time t is longer than the predetermined time s (S6). The predetermined value s is set to a value larger than the predetermined time b, and is used as a unit time for decreasing the screen saver execution waiting time W as described later, and is set to 60 seconds, for example.
[0033]
Here, if it is determined that the maintenance time t of the screen saver screen is longer than the predetermined time s (YES in S6), it is further determined whether or not the current screen saver execution waiting time W is longer than the predetermined time s. If it is determined that it is large (S8), the screen saver execution waiting time W is reduced by the time s according to the following equation (3) (S9).
[0034]
W = W-s (3)
After switching to the screen saver screen, the above process is repeated each time the user inputs an operation and returns from the screen saver screen to the process corresponding screen. In the process, when the maintenance time t of the measured screen saver screen is shorter than the predetermined time b, it is considered that the user does not need the screen saver screen, and the screen saver execution waiting time W is sequentially increased in units of time a. The In this case, the continuation time of the processing corresponding screen is sequentially increased.
[0035]
On the other hand, when the maintenance time t of the measured screen saver screen is longer than the predetermined time s, emphasis is placed on preventing the burn-in of the display unit, and the screen saver execution waiting time W is sequentially reduced in units of time s. In this case, the time for which the processing corresponding screen is continued is sequentially shortened.
In this way, when the screen saver execution waiting time is controlled, when it can be considered that the user does not need the screen saver, the display time of the processing-compatible screen becomes longer, and the user uses the computer device to perform more efficient work. It can be performed. Also, if the user does not necessarily consider that the screen saver screen is not necessary, that is, it can be considered that there is little work to be done while looking at the processing-compatible screen, an earlier timing is given so that priority is given to preventing the burn-in of the display unit. With this, switching from the processing support screen to the screen saver screen is performed.
[0036]
When the flag F is set to “0” (NO in S4), the measurement time t of the screen saver screen is not measured, assuming that the variable function of the screen saver execution waiting time is not used in the process. Although (S1 to S3), the subsequent processing is not performed. If the measured screen saver screen duration t is smaller than the predetermined time s (NO in S6), the process ends without changing the screen saver execution waiting time W in particular. Furthermore, when the screen saver execution waiting time W is smaller than the unit time s of decrease (NO in S8), no further subtraction processing is performed.
[0037]
In the above example, the auxiliary storage unit 60 shown in FIG. 1 corresponds to the storage means. Of the processes shown in FIG. 2, the process at step (S1) corresponds to the first time acquisition means, the process at step (S2) corresponds to the second time acquisition means, and the process at step (S3). The processing corresponds to time calculation means, the processing in step (S7) corresponds to waiting time extension means, the processing in step (S9) corresponds to waiting time reduction means, and the processing in steps (S4 to S9) Corresponds to the waiting time control means.
[0038]
【The invention's effect】
As described above, according to the first to fourth aspects of the present invention, it can be determined whether or not the user needs a screen saver based on the maintenance time of the screen saver screen. Therefore, based on the maintenance time of the screen saver screen. By controlling the timing of switching from the processing-compatible screen to the screen saver function, the screen saver execution waiting time reflects the user's work state.
[0039]
Further, according to the present invention described in claim 5, it is possible to provide a recording medium storing a program for causing a computer to perform the processing in the screen saver control device.
