The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of a first embodiment of a control method provided by the present invention is shown, where the method may be applied to an electronic device, where the electronic device may be a mobile phone, a pad, or other terminal device that is provided with a projection module and has a projection function, and the electronic device may show projection content to a user on a projection area through the projection module of the electronic device. As shown in fig. 2a, the projection module of the electronic device has a direct projection effect, the electronic device is placed on a desktop in a flat manner, the projection module of the electronic device is close to or in contact with the desktop, and display content is projected on a wall surface perpendicular to the desktop through the projection module of the electronic device; as shown in fig. 2b, the projection module of the electronic device has an oblique projection effect, the electronic device has an angle with the desktop, the electronic device in fig. 2b is vertically placed and perpendicular to the desktop, the projection module thereof has a certain distance with the desktop, and the electronic device projects display content on the desktop through the projection module thereof.
The display content projected on the projection area by the projection module of the electronic device may be display content such as video or document, or display content such as a virtual keyboard, and the electronic device may respond to an operation of a user on the projection area.
In this embodiment, the method may include the following steps to achieve the object of the present invention:
step 101: when a projection module of the electronic equipment is in an open state, monitoring an operation body gesture of a projection area of the projection module.
Taking an oblique projection example as shown in fig. 2c as an example, a projection module y of the electronic device x is in an open state, display content w is projected on the projection area z, and the display content may be a virtual keyboard, video content, document content, or the like.
Step 102: when the gesture of the operation body does not appear in the projection area within a first preset time, the projection module is kept in an opening state, and the light source of the projection module is controlled to be switched from a first power consumption mode to a second power consumption mode.
Wherein a first power consumption value of the light source in the first power consumption mode is higher than a second power consumption value of the light source in the second power consumption mode.
It should be noted that the light source is a light source for the projection module to project display content in the projection area, a first power consumption mode of the light source is a working mode of the light source in a current state, at this time, the light source has a first power consumption value, and when an operation body gesture is not monitored in a first preset time period on the projection area in this embodiment, it indicates that a user has not operated the projection area for the first preset time period, at this time, the embodiment may control the light source to reduce its current power consumption while keeping the projection module in an on state, that is, the light source is switched from the first power consumption mode with the first power consumption value to a second power consumption mode with a second power consumption value, and the second power consumption mode is the working mode after the light source is switched.
In a specific implementation, the second power consumption mode may be a mode in which the light source is turned off, that is, the projection module is controlled to be in an off state while being in an on state, at this time, the second power consumption value of the light source is 0, that is, when the gesture of the operation body is not monitored on the projection area for the first preset time, the light source of the projection module is directly turned off in this embodiment, but the projection module is not turned off.
In addition, the second power consumption value may not be 0 but be a value smaller than the first power consumption value, for example, the second power consumption value is half of the first power consumption value, at this time, the scheme of this embodiment may be executed again on the electronic device, that is, the operator gesture in the projection area of the projection module is continuously monitored, and when the operator gesture still does not occur in the projection area within the first preset time or another preset time, the projection module may be selected to be continuously kept in the on state, but the projection module is directly controlled to be turned off, and the projection content is stopped being projected onto the projection area, so that the power consumption of the projection module is reduced to the maximum extent without turning off the projection module.
In view of the above, in the first embodiment of the control method provided by the present invention, when the projection module of the electronic device is in the on state, the gesture of the operation body on the corresponding projection area is monitored, and when the gesture of the operation body does not occur in the projection area for the first preset time, namely, the light source of the projection module is controlled to be switched from a first power consumption mode with high power consumption to a second power consumption mode with low power consumption while the projection module is kept in an opening state, in this scheme, the embodiment switches the power consumption mode of its projection light source without turning off the projection module, because the main power consumption of the electronic device in the projection mode is from the projection light source, the embodiment can reduce the power consumption of the projection module and even the electronic device on the premise of avoiding frequently turning off and starting the projection module, thereby achieving the purpose of the embodiment.
Based on the implementation scheme of the foregoing embodiment, since the power consumption of the light source of the projection module is directly related to the output current thereof, referring to fig. 3, there is provided a flowchart of a second embodiment of the control method provided by the present invention, wherein the step 102 may be implemented by the following steps:
step 121: when the gesture of the operation body appears in the projection area within a first preset time, the projection module is kept in an opening state, and the output current of the light source is controlled to be reduced from a first current value to a second current value.
When the light source output current is the first current value, the light source has a first power consumption value, and when the light source output current is the second current, the light source has a second power consumption value.
That is, in the present embodiment, the output current of the light source of the projection module is controlled to achieve the purpose of reducing the power consumption of the projection module.
It should be noted that the second current value may be 0, that is, in this embodiment, when the gesture of the operation body is not monitored on the projection area for the first preset time, the output current of the light source of the projection module is directly reduced to 0, and the light source is stopped from projecting the display content to the projection area by using the output current, so as to reduce the power consumption of the projection module to the maximum extent, but the projection module is not turned off.
In addition, the second current value may not be 0, but may be a value smaller than the first current value, for example, the second current value is half of the first current value, for example, when an operation body gesture is not monitored on the projection region for the first preset time, the display brightness of the display content projected on the projection region by the projection module through the light source thereof is reduced, at this time, the scheme of this embodiment may be executed again on the electronic device, that is, the operation body gesture of the projection region of the projection module is continuously monitored, when the operation body gesture still does not occur on the projection region for the first preset time or another preset time, the projection module may be selected to be continuously maintained in the on state, but the output current of the light source of the projection module is directly controlled to be 0, that is, the light source is directly turned off, and stopping projecting the display content onto the projection area so as to reduce the power consumption of the projection module to the maximum extent without turning off the projection module.
Referring to fig. 4, a flowchart of a third embodiment of the control method provided by the present invention is shown, where after the step 102, the method may further include the following steps:
step 103: and generating a call-out instruction.
The evoking instruction may be triggered by a user or generated according to preset configuration information, for example, after the light source is in the second power consumption mode for a second preset time, the electronic device generates the evoking instruction.
Step 104: and controlling the light source to be switched from the second power consumption mode to the first power consumption mode based on the awakening instruction.
That is to say, in this embodiment, the generated call instruction is responded, and the recovery of the working state of the light source is controlled, that is, the light source is controlled to be switched from the second power consumption mode to the first power consumption mode.
In a specific implementation, the evoking instruction of step 103 may be that after the light source is controlled to be switched from the first power consumption mode to the second power consumption mode in step 102, the gesture of the operation body in the projection area is continuously monitored, and then if the gesture of the operation body is monitored in the projection area, the evoking instruction generated at this time indicates that the user operates the display content on the projection area at this time, so that the projection state of the projection mode needs to be restored, that is, the light source of the projection module is controlled to be restored to the first power consumption mode.
In addition, when the step 103 generates a call instruction, it may also be implemented by the steps shown in fig. 5:
step 131: and receiving operation data generated by the operation of an operation body on the electronic equipment, wherein the operation data points to the projection module.
Step 132: and generating a call-up instruction according to the operation data.
That is, after the light source of the projection module is in the second power consumption mode, the user can operate the electronic device through the operating body, for example, clicking a display screen on the electronic device corresponding to the display content on the projection area of the projection module or colliding with a lens of the projection module on the electronic device, and the like, at this time, the electronic device may generate corresponding operation data due to the operation of the user's operation body, the operation data points to the projection module, then the operation data is identified, whether the operation data is the operation data which reminds the projection function of the projection module again is judged, and further generates the evoking instruction when the operation data is the operation data for evoking the projection function of the projection module again, and controlling the light source of the projection module to be recovered from the second power consumption mode to the first power consumption mode.
Based on the foregoing embodiments, various sensors may be implemented when monitoring an operation gesture on the projection area. For example, the infrared sensor monitors whether the projection area has infrared imaging data corresponding to the operation body so as to monitor the gesture of the operation body on the projection area; or the self-capacitance sensor monitors the gesture of the operation body on the projection area by monitoring the capacitance change state of the self-capacitance sensor; or the image acquisition equipment such as a camera acquires the image data on the projection area, and then identifies the operation body imaging in the image data so as to monitor the gesture of the operation body on the projection area. In addition, the monitoring of the gesture of the operation body may also be implemented by a light output module on the electronic device, such as an infrared light source, at this time, referring to fig. 6, which is an implementation flowchart of step 101 in the fourth embodiment of the control method provided by the present invention, where step 101 may also be implemented by the following steps:
step 111: when a light output module of the electronic equipment emits light to the projection area, light state change information generated by the operation of the light on the projection area due to the operation of the operation body is collected.
As shown in fig. 2d, the light output module t may be an infrared light source, where the infrared light source emits a bundle of planar light s parallel to the desktop where the projection area is located, and when the operating body contacts the desktop where the projection area is located, the light path may be shielded, so that light state changes occur, for example, light spots are formed between fingers of the operating body.
Step 112: and monitoring the light state change information to monitor the gesture of the operation body.
That is to say, in this embodiment, the change monitoring is performed on the planar light on the projection area, when the light state of the planar light changes, it can be shown that an operation body appears on the projection area, so that the gesture of the operation body is monitored, and if the light state change does not appear in the projection area within a first preset time period, that is, it is shown that the gesture of the operation body does not appear, at this time, this embodiment keeps the projection module in an on state, and controls the light source of the projection module to be switched from the first power consumption mode to the second power consumption mode, so as to reduce the power consumption, thereby achieving the purpose of this embodiment.

And a gesture monitoring subunit 712, configured to monitor the light state change information to monitor the gesture of the operation body.
That is to say, in this embodiment, the change monitoring is performed on the planar light on the projection area, when the light state of the planar light changes, it can be shown that an operation body appears on the projection area, so that the gesture of the operation body is monitored, and if the light state change does not appear in the projection area within a first preset time period, that is, it is shown that the gesture of the operation body does not appear, at this time, this embodiment keeps the projection module in an on state, and controls the light source of the projection module to be switched from the first power consumption mode to the second power consumption mode, so as to reduce the power consumption, thereby achieving the purpose of this embodiment.
In addition, the present invention further provides an embodiment nine of an electronic device, where the electronic device may include a control device for a mobile phone, a pad, and other terminal devices that are provided with a projection module and have a projection function, and the electronic device may display projection content to a user on a projection area through the projection module of the electronic device. As shown in fig. 2a, the projection module of the electronic device has a direct projection effect, the electronic device is placed on a desktop in a flat manner, the projection module of the electronic device is close to or in contact with the desktop, and display content is projected on a wall surface perpendicular to the desktop through the projection module of the electronic device; as shown in fig. 2b, the projection module of the electronic device has an oblique projection effect, the electronic device has an angle with the desktop, the electronic device in fig. 2b is vertically placed and perpendicular to the desktop, the projection module thereof has a certain distance with the desktop, and the electronic device projects display content on the desktop through the projection module thereof.
The display content projected on the projection area by the projection module of the electronic device may be display content such as video or document, or display content such as a virtual keyboard, and the electronic device may respond to an operation of a user on the projection area.
Referring to fig. 12, a schematic structural diagram of the electronic device in the embodiment of the present invention is shown, where the electronic device may further include the following structure besides the projection module 1201:
a control device 1202, where the control device 1202 is configured to monitor an operation body gesture of a projection area of the projection module 1201 of the electronic device when the projection module 1201 is in an on state, and when the operation body gesture does not occur in the projection area within a first preset time period, keep the projection module 1201 in the on state, and control the light source 1203 of the projection module 1201 to be switched from the first power consumption mode to the second power consumption mode.
Wherein a first power consumption value of the light source in the first power consumption mode is higher than a second power consumption value of the light source in the second power consumption mode.
Taking an oblique projection example as shown in fig. 12 as an example, a projection module 1201 of the electronic device is in an open state, display content w is projected on the projection area z, where the display content may be a virtual keyboard, video content, document content, or the like, and the control device 1202 in this embodiment monitors whether an operation body gesture exists on the projection area, which is different from a gesture type that the operation body gesture is recognized to obtain the operation body gesture.
It should be noted that the light source 1203 is a light source for the projection module 1201 to project the display content in the projection area, the first power consumption mode of the light source 1203 is an operating mode of the light source 1203 in the current state, at this time, the light source 1203 has a first power consumption value, in this embodiment, when the control device 1202 does not monitor the gesture of the operation body on the projection area within the first preset time period, indicating that the user has not operated the projection area for the first preset time, at this time, the control device 1202 may control the light source 1203 to reduce its current power consumption while keeping the projection module 1201 in the on state, that is, the light source 1203 is switched from a first power consumption mode with a first power consumption value to a second power consumption mode with a second power consumption value, where the second power consumption mode is a working mode after the light source 1203 is switched.
In a specific implementation, the second power consumption mode may be a mode in which the light source 1203 is turned off, that is, the projection module 1201 is in an on state while controlling the light source 1203 to be in an off state, at this time, a second power consumption value of the light source 1203 is 0, that is, when the control device 1202 does not monitor the gesture of the operation body on the projection area for the first preset time, the light source 1203 of the projection module 1201 is directly turned off, but the projection module 1201 is not turned off.
In addition, the second power consumption value may not be 0, but may be a value smaller than the first power consumption value, for example, the second power consumption value is half of the first power consumption value, at this time, the control device 1202 of this embodiment may be run again on the electronic device, that is, the control device 1202 continues to monitor the operator gesture in the projection area of the projection module 1201, and when the operator gesture still does not occur in the projection area within the first preset time or another preset time, the projection module 1201 may be selected to continue to be kept in the on state, but directly control the projection module 1201 to be turned off, and stop projecting the display content onto the projection area, so as to reduce the power consumption of the projection module 1201 to the maximum extent without turning off the projection module 1201.
In view of the above, in the ninth embodiment of the electronic device, when the projection module of the electronic device is in the on state, the gesture of the operation body on the corresponding projection area is monitored, and when the gesture of the operation body does not occur in the projection area for the first preset time, namely, the light source of the projection module is controlled to be switched from a first power consumption mode with high power consumption to a second power consumption mode with low power consumption while the projection module is kept in an opening state, in this scheme, the embodiment switches the power consumption mode of its projection light source without turning off the projection module, because the main power consumption of the electronic device in the projection mode is from the projection light source, the embodiment can reduce the power consumption of the projection module and even the electronic device on the premise of avoiding frequently turning off and starting the projection module, thereby achieving the purpose of the embodiment.
