Mode for Carrying Out the Invention

[0010] (Background Leading to the Present Disclosure) For example, in an electronic device powered by a battery, such as a laptop computer or a tablet computer, the remaining time that the battery can drive the electronic device changes due to a predetermined operation. For example, the power consumption of a liquid crystal display accounts for a large proportion of the overall battery consumption of the electronic device. Therefore, when the brightness of the liquid crystal display is decreased, the remaining battery time becomes longer, and conversely, when the brightness of the liquid crystal display is increased, the remaining battery time becomes shorter.

[0028] With such a configuration, the usability of the user can be improved.

[0029] Hereinafter, embodiments will be described with reference to the drawings.

[0030] (Embodiment 1) [Overall Configuration] FIG. 1 is a perspective view showing the appearance of the electronic device 1 according to Embodiment 1. FIG. 2 is a block diagram showing the functional configuration of the electronic device 1 in FIG. 1.

[0031] As shown in FIGS. 1 and 2, the electronic device 1 includes a display unit 10 that displays an image and a control unit 20 that controls the display unit 10, and is an electronic device supplied with a driving power source from a battery 30. Further, as shown in FIG. 2, the electronic device 1 is a so-called laptop computer, and has a configuration in which the display unit 10 is rotatably attached to the main body 40.

[0032] The display unit 10 is a device capable of displaying an image such as a liquid crystal display or an organic EL display, for example.

[0033] The display unit 10 can change the luminance indicating the brightness of the screen by a user operation. For example, the luminance when the display unit 10 is in the brightest state is indicated as 100%, and the luminance when the display unit 10 is in the darkest state is indicated as 0%. The user can arbitrarily change the luminance of the display unit 10 between 0% and 100%.

[0034] The control unit 20 can be configured by, for example, a CPU, MPU, DSP, FPGA, ASIC, etc. The control unit 20 may be configured by hardware only, or may be realized by combining hardware and software. The control unit 20 realizes a predetermined function by reading data and programs stored in a storage area (not shown) in the control unit 20 and performing various arithmetic processes.

[0035] The control unit 20 can display on the display unit 10 the remaining time that the electronic device 1 can be driven by the battery 30. Further, when the control unit 20 detects a change operation on the electronic device 1, the control unit 20 can display on the display unit 10 how much the remaining time of the battery 30 has changed.

[0036] The change operation on the electronic device 1 means an operation of a device that affects the power consumption of the battery 30. In the present embodiment, as an example of the change operation, the change in the brightness of the display unit 10 will be described. For example, when the brightness of the display unit 10 is changed by the user, the control unit 20 can display on the display unit 10 how much the remaining time of the battery has increased or decreased, and notify the user.

[0037] In the present embodiment, as a functional configuration, the control unit 20 includes a change operation detection unit 21, a power consumption calculation unit 22, a battery remaining amount detection unit 23, and a remaining time calculation unit 24.

[0038] The change operation detection unit 21 detects a change operation on the electronic device 1 by the user. In the present embodiment, the change operation detection unit 21 detects, for example, the brightness of the display unit 10 set by the user's operation. The change operation detection unit 21 compares the set value of the brightness of the display unit 10 before the change operation with the set value after the change operation, and can detect a change in the brightness of the display unit 10 as a change operation when there is a change in the set value of the brightness of the display unit 10. Note that the change operation detection unit 21 may include a sensor that detects the brightness of the display unit 10, or may be configured to detect a change operation by detecting a change in the brightness of the display unit 10.

[0039] The power consumption calculation unit 22 calculates a first power consumption of the battery during a predetermined period before the change operation, a second power consumption of the device that is the target of the change operation during a predetermined period before the change operation, and a third power consumption of the device that is the target of the change operation during a predetermined period after the change operation. The power consumption calculation unit 22 can measure, for example, the value of current or voltage in the battery 30 and the device that is the target of the change operation, and calculate the power consumption based on the value of current or voltage.

[0040] The battery remaining amount detection unit 23 detects the remaining amount of the battery 30. The battery remaining amount detection unit 23 can detect the remaining amount of the battery 30 based on, for example, the voltage of the battery 30 during charging and the voltage of the battery 30 during discharging.

[0041] The remaining time calculation unit 24 calculates the change in the remaining time of the battery 30 due to the change operation based on the first power consumption, the second power consumption, the third power consumption, and the remaining amount of the battery. The remaining time calculation unit 24 can calculate how much the remaining time of the battery 30 has changed from the power consumption of the entire electronic device 1 (the first power consumption) and the power consumption before and after the change operation (the second power consumption and the third power consumption).

[0042] Specifically, the remaining time calculation unit 24 calculates the remaining time of the battery 30 before the change operation based on the first power consumption and the remaining amount of the battery. Assuming the remaining amount of the battery is A and the first power consumption is B, the remaining time of the battery 30 before the change operation can be expressed by the formula A / (B / 60).

[0043] Next, the remaining time calculation unit 24 calculates the remaining time of the battery 30 after the change operation based on the first power consumption, the second power consumption, the third power consumption, and the remaining amount of the battery. Assuming the remaining amount of the battery is A, the first power consumption is B, the second power consumption is C, and the third power consumption is D, the remaining time of the battery 30 after the change operation can be expressed by the formula A / ((B - C + D) / 60).

[0044] The change in the remaining time of the battery 30 is calculated by calculating the difference between the remaining time of the battery 30 before the change operation and the remaining time of the battery 30 after the change operation. That is, assuming the remaining amount of the battery is A, the first power consumption is B, the second power consumption is C, and the third power consumption is D, the change in the remaining time of the battery 30 can be expressed by the formula A / ((B - C + D) / 60) - A / (B / 60).

[0045] [Operation] Referring to FIG. 3, the operation of displaying the change in the remaining time of the battery 30 due to a change operation will be described. FIG. 3 is a flowchart for explaining the operation of displaying the change in the remaining time of the battery 30 due to a change operation on the electronic device 1. Here, as the change operation, the change in the brightness of the display unit 10 by the user will be described as an example.

[0046] The control unit 20 determines whether a change operation on the electronic device 1 by the user has been detected by the change operation detection unit 21 (step S11). The change operation detection unit 21 detects a change operation, for example, when there is a change in the set value of the brightness of the display unit 10. The case where there is a change in the set value means, for example, that the change operation detection unit 21 receives a signal for changing the brightness of the display unit 10 through an input interface such as a mouse or a keyboard. Alternatively, the change in the brightness of the display unit 10 may be detected as a change operation by a brightness sensor or the like. If no change operation is detected (No in step S11), the control unit 20 waits until a change operation is detected.

[0047] When a change operation is detected (Yes in step S11), the power consumption calculation unit 22 calculates the first power consumption of the battery 30 for a predetermined period before the change operation (step S12). The power consumption calculation unit 22 calculates the first power consumption based on, for example, the value of the current or voltage of the battery 30 for a predetermined period before the change operation is detected. The predetermined period before the change operation refers to, for example, a few minutes before the change operation, with the time point when the change operation is detected as the reference. The predetermined period can be appropriately changed according to the type of change operation and the like. The first power consumption is the total power consumption consumed by the electronic device 1 during the predetermined period before the change operation.

[0048] Further, the power consumption calculation unit 22 calculates the second power consumption of the device to be the target of the change operation during a predetermined period before the change operation (step S13). The power consumption calculation unit 22 calculates the second power consumption based on, for example, the current or voltage value of the display unit 10 during a predetermined period before the change operation is detected. In the present embodiment, the device to be the target of the change operation refers to the display unit 10 whose brightness has been changed. In step S13, the power consumption (second power consumption) of the display unit 10 during a predetermined period before the change operation is calculated.

[0049] Also, the battery remaining amount detection unit 23 detects the remaining amount of the battery 30 when the change operation is detected (step S14). For example, the remaining amount of the current battery 30 is detected with the fully charged state being 100%.

[0050] Further, the power consumption calculation unit 22 calculates the third power consumption of the device to be the target of the change operation during a predetermined period after the change operation (step S15). The power consumption calculation unit 22 calculates the third power consumption based on, for example, the current or voltage value of the display unit 10 during a predetermined period after the change operation is detected. The predetermined period after the change operation refers to, for example, several seconds after the change operation, with the time point when the change operation is detected as the reference. The predetermined period can be appropriately changed according to the type of the change operation or the like. In step S15, the power consumption (third power consumption) of the display unit 10 during a predetermined period after the change operation is calculated.

[0051] In the electronic device 1, the first power consumption, the second power consumption, the battery remaining amount, and the third power consumption are calculated or detected triggered by the detection (step S11) of the change operation on the electronic device 1 by the user.

[0052] Next, the remaining time calculation unit 24 calculates the change in the remaining time of the battery 30 based on the first power consumption, the second power consumption, the remaining amount of the battery 30, and the third power consumption (step S16). The change in the remaining time of the battery refers to how much the remaining time of the battery has increased or decreased due to the change operation, and hereinafter may also be referred to as the power saving effect. Specifically, the remaining time calculation unit 24 calculates the remaining time of the battery 30 before the change operation based on the first power consumption and the remaining amount of the battery. Next, the remaining time calculation unit 24 calculates the remaining time of the battery 30 after the change operation based on the first power consumption, the second power consumption, the third power consumption, and the remaining amount of the battery. The change in the remaining time of the battery 30 is calculated by calculating the difference between the remaining time of the battery 30 before the change operation and the remaining time of the battery 30 after the change operation.

[0053] The power saving effect is calculated based on the total power consumption of the electronic device 1 before the change operation (the first power consumption), how much the power consumption of the device to be changed has changed before and after the change operation (the second power consumption and the third power consumption), and the remaining amount of the battery 30 at the time when the change operation is detected. The power saving effect is indicated by the increase or decrease in the remaining time, for example, "the remaining time of the battery has increased by 90 minutes".

[0054] By calculating the power consumption of the display unit 10 before the change operation (the second power consumption) and the power consumption of the display unit 10 after the change (the third power consumption), the increase or decrease in the power consumption of the display unit 10 due to the change operation can be calculated. Based on the increase or decrease in the power consumption of the display unit 10 before and after the change operation, the increase or decrease in the remaining time of the battery 30 after the change operation is calculated as the power saving effect. In this case, the change in the remaining time of the battery 30 can be calculated, for example, within about several seconds after detecting the change operation.

[0055] Next, the control unit 20 displays the change in the remaining time of the battery 30 (power saving effect) on the display unit 10 (step S17), and ends the process. FIG. 4 is a diagram showing an example of the display of the change in the remaining time of the battery 30. As shown in FIG. 4, the display of the power saving effect can be performed, for example, by a pop-up 11 in a part of the display unit 10.

[0056] In this way, the power saving effect can be immediately notified by using the change operation of the user on the electronic device 1 as a trigger. Further, by displaying the power saving effect by the pop-up 11, the change in the remaining time can be immediately notified to the user from the change operation without disturbing the user's work.

[0057] FIG. 5 is an enlarged view of the pop-up 11 in FIG. 4. As shown in FIG. 5, when the brightness of the display unit 10 is changed, a notification such as "The remaining time has increased by 90 minutes due to the change in the brightness of the display compared to the last 15 minutes" can be displayed in the pop-up 11. If the remaining time does not change as a result of calculating the change in the remaining time of the battery 30, a display such as "The remaining time does not change due to the change in the brightness of the display" may be made.

[0058] Also, by clicking the button 12 in the pop-up 11, detailed information 13 regarding the change in the remaining time of the battery (see FIG. 6) may be displayed. Alternatively, the detailed information 13 can be displayed by launching an application that displays the power saving effect.

[0059] FIG. 6 is a diagram showing an example of detailed information 13 regarding changes in the remaining time of the battery. FIG. 7 is an enlarged view of the detailed information 13 in FIG. 6. When the button 12 in the pop-up 11 of FIGS. 4 and 5 is clicked, as shown in FIG. 6, the detailed information 13 is displayed on the display unit 10. As shown in FIG. 7, in the detailed information 13, for example, a graph showing time on the horizontal axis and the remaining amount of the battery on the vertical axis is displayed. In the detailed information 13 of FIG. 7, the remaining amount of the battery 30 at that time is indicated by the bar graph 13a, the remaining time of the battery 30 before the brightness of the display unit 10 is changed (before the change operation) is indicated by the dashed line 13b, and the remaining time of the battery 30 after the change operation is indicated by the solid line 13c. Note that the display method is not limited to a solid line and a dashed line, and any display that can distinguish between before the change operation and after the change operation may be used.

[0060] In the detailed information 13 of FIG. 7, the remaining time of the battery before the brightness of the display unit 10 is changed is indicated by the dashed line 13b, and the remaining time of the battery after the brightness of the display unit 10 is changed is indicated by the solid line 13c. That is, the remaining time of the battery before the change operation and the remaining time of the battery after the change operation are displayed superimposed. By using such a display, it is possible to visually and easily notify the user of how much the remaining time of the battery has increased or decreased due to the change in brightness.

[0061] In the detailed information 13 of FIG. 7, the change in the remaining amount of the battery 30 over time can be visually recognized by the bar graph. For example, in a time period when the remaining amount of the battery is less than 50%, by changing the color of the graph or the like, it is possible to visually and easily notify the user of which time period had a greater battery consumption.

[0062] [Effect] According to the above-described embodiment, it is possible to provide the electronic device 1 that improves the usability for the user. Triggered by a change operation on the electronic device 1 by the user, the change in the remaining time of the battery 30 can be immediately displayed. Therefore, the convenience of the electronic device 1 can be improved.

[0063] Since it is possible to immediately display the change in the remaining time of the battery 30 due to the user's change operation, it is useful when it is desired to know the remaining time of the battery 30, such as when the electronic device 1 cannot be externally powered.

[0064] In the above-described embodiment, the change in the brightness of the display unit 10 is described as an example of the change operation. However, the change operation is not limited to this. For example, the change operation may be the connection or disconnection of a peripheral device to the electronic device 1. For example, when a peripheral device is connected to or disconnected from the electronic device 1 via an input / output terminal such as a USB provided in the electronic device 1, the change in the remaining time of the battery 30 can be calculated.

[0065] In step S11 of FIG. 3, the change operation detection unit 21 can detect a change operation by detecting, for example, that a peripheral device is connected or disconnected to / from the input / output terminal. The connection or disconnection of the peripheral device can be detected, for example, by the presence or absence of physical contact with the input / output terminal, or by a change in current or voltage at the input / output terminal.

[0066] In this case, in step S13 of FIG. 3, the power consumption calculation unit 22 calculates (second power consumption calculation) the power consumption of the peripheral device during a predetermined period before the change operation (connection or disconnection of the peripheral device). In step S13, the power consumption calculation unit 22 calculates the second power consumption based on, for example, the current or voltage of the peripheral device. Also, in step S15 of FIG. 3, the power consumption calculation unit 22 calculates (third power consumption calculation) the power consumption of the peripheral device during a predetermined period after the change operation. In step S15, the power consumption calculation unit 22 calculates the third power consumption based on, for example, the current or voltage of the peripheral device.

[0067] When the change operation is the connection of a peripheral device to the electronic device 1, since the peripheral device is not connected before the change operation, no power is consumed, and the second power consumption is calculated as 0. On the other hand, when the change operation is the disconnection of a peripheral device from the electronic device 1, since the peripheral device is not connected after the change operation, no power is consumed, and the third power consumption is calculated as 0.

[0068] Alternatively, when the electronic device 1 includes a wireless communication unit that performs wireless communication with an external device, the change operation may be the turning on or off of the wireless communication unit. The wireless communication unit can communicate with an external device according to a wireless communication standard such as, for example, wireless LAN, wireless WAN, Bluetooth (registered trademark), or infrared rays. Based on the turning on or off of the wireless communication unit as a trigger, the change in the remaining time of the battery 30 can be calculated.

[0069] In step S11 of FIG. 3, the change operation detection unit 21 can detect a change operation by detecting, for example, a signal for turning on or off the wireless communication unit through an input interface such as a keyboard.

[0070] In this case, in step S13 of FIG. 3, the power consumption calculation unit 22 calculates (second power consumption calculation) the power consumption of the wireless communication unit for a predetermined period before the change operation (turning on or off of the wireless communication unit). In step S13, the power consumption calculation unit 22 calculates the second power consumption based on, for example, the current or voltage of the wireless communication unit. Also, in step S15 of FIG. 3, the power consumption calculation unit 22 calculates (third power consumption calculation) the power of the wireless communication unit for a predetermined period after the change operation. In step S15, the power consumption calculation unit 22 calculates the third power consumption based on, for example, the current or voltage of the wireless communication unit.

[0071] When the change operation is the turning on of the wireless communication unit, since the wireless communication unit is off before the change operation, no power is consumed, and the second power consumption is calculated as 0. On the other hand, when the change operation is the turning off of the wireless communication unit, since the wireless communication unit is off after the change operation, no power is consumed, and the third power consumption is calculated as 0.

[0072] Alternatively, the change operation may be the startup or termination of an application in the electronic device 1.

[0073] In the above-described embodiment, an example has been described in which the change in the remaining time of the battery 30 is calculated by using a change operation by the user as a trigger, but the present invention is not limited thereto. For example, the brightness of the display unit 10 may be changed according to the change in the brightness around the electronic device 1. In this case, the change in the brightness around the electronic device 1 serves as a trigger, and the change in the remaining time of the battery 30 is calculated.

[0074] In the above-described embodiment, an example in which the electronic device 1 is a laptop computer has been described, but the present invention is not limited thereto. The electronic device 1 may be an electronic device that is powered by a battery, such as a tablet PC or a smartphone.

[0075] In the above-described embodiment, an example in which the change in the remaining time of the battery 30 is displayed by a pop-up has been described, but the present invention is not limited thereto. For example, the change in the remaining time of the battery 30 may be notified by voice.

[0076] (Embodiment 2) Embodiment 2 will be described with reference to FIGS. 8 to 9B. In Embodiment 2, the same reference numerals are given to the same or equivalent configurations as those in Embodiment 1, and the description thereof will be omitted for the sake of brevity.

[0077] FIG. 8 is a block diagram showing the internal configuration of the electronic device 2 according to Embodiment 2. FIG. 9A is a graph showing the correlation between the brightness and the power consumption of the display unit 10. FIG. 9B is a diagram showing an example of the conversion table of the electronic device 2 in FIG. 8.

[0078] Embodiment 2 is different from Embodiment 1 in that it includes a conversion table 25 showing the relationship between the magnitude of the brightness of the display unit 10 and the magnitude of the third power consumption as shown in FIG. 8.

[0079] The conversion table 25 is, as shown in FIG. 9B, for example, a table that associates the luminance of the display unit 10 with the power consumption of the display unit 10, based on the correlation between the luminance and the power consumption of the display unit 10 shown in FIG. 9A. With the conversion table 25, the power consumption of the display unit 10 can be calculated according to the luminance of the display unit 10. For example, with the conversion table 25, when the luminance of the display unit 10 is 0% or more and 10% or less, the power consumption is A1, and when it is 11% or more and 20% or less, the power consumption is A2, and thus the power consumption corresponding to the luminance can be calculated. The conversion table 25 is stored, for example, in the storage unit of the electronic device 1.

[0080] Next, with reference to FIG. 10, an operation of displaying the change in the remaining time of the battery 30 due to the change operation in the second embodiment will be described. FIG. 10 is a flowchart for explaining an operation of displaying the change in the remaining time of the battery 30 due to a change operation on the electronic device 2. In FIG. 10, step S21 has the same content as step S11 in FIG. 3, steps S23 to S25 have the same content as steps S12 to S14 in FIG. 3, and steps S27 to S28 have the same content as steps S16 to S17 in FIG. 3, and thus the description thereof will be omitted.

[0081] When a change in the luminance of the display unit 10 is detected (step S21), the change operation detection unit 21 detects the luminance of the display unit 10 after the change operation (step S22). The luminance of the display unit 10 can be detected, for example, by reading the set value of the luminance of the display unit 10 after the detection of the change operation. Alternatively, the change operation detection unit 21 may include a luminance sensor and detect the luminance of the display unit 10.

[0082] In step S26, the power consumption calculation unit 22 calculates a third power consumption based on the conversion table 25 from the luminance of the display unit 10 detected in step S22. By calculating the third power consumption using the conversion table 25, the change in the remaining time of the battery 30 can be calculated more quickly.

[0083] The conversion table 25 may be designed, for example, in consideration of the characteristics of each individual electronic device 2. In this case, for each individual electronic device 2, the change in the remaining time of the battery 30 can be calculated more accurately.

[0084] [Effect] According to the above-described embodiment, by using the conversion table 25, the change in the remaining time of the battery 30 can be calculated more quickly. Therefore, the user can know the change in the remaining time immediately after the change in the brightness of the display unit 10 is detected, and the convenience is improved.

[0085] Note that, in the above-described embodiment, an example in which the electronic device 2 has one conversion table 25 has been described, but the present invention is not limited thereto. For example, the electronic device 2 may have two conversion tables: a conversion table for cold regions where the battery 30 is consumed severely, and another conversion table. In this case, the change in the remaining time of the battery 30 can be calculated more accurately according to the environment in which the electronic device 2 is used. Alternatively, the values of the conversion table may be updated due to the deterioration of the battery 30 over time. For example, the values of the conversion table can be updated based on the prediction from the usage status of the electronic device up to that point.
