Detailed Description
In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating a method for adjusting power consumption of a camera according to an exemplary embodiment, and as shown in fig. 1, the method for adjusting power consumption of a camera according to an embodiment of the disclosure may include the following steps:
s101, acquiring the power consumption level of the camera.
It should be noted that, the execution body of the method for adjusting the power consumption of the camera according to the embodiments of the present disclosure is the device for adjusting the power consumption of the camera according to the embodiments of the present disclosure, and the device may be disposed in an electronic device, for example, a mobile phone, a single-lens reflex, a digital camera, and other terminal devices, so as to execute the method for adjusting the power consumption of the camera according to the embodiments of the present disclosure.
In the embodiment of the disclosure, the camera may be understood as an image pickup device in a terminal device such as a mobile phone, a single-lens reflex and a digital camera, and after the camera is turned on, power consumption is detected to obtain power consumption parameter data of the camera, for example, by continuously obtaining data of a battery node of the camera device, a power consumption value after the camera is turned on is determined according to the data, so as to determine a power consumption level corresponding to the power consumption value after the camera is turned on.
Here, it should be noted that a correspondence relationship between the power consumption level of the camera and the power consumption value of the camera may be preset, for example, dividing different power consumption intervals respectively corresponds to three levels of high power consumption, medium power consumption and low power consumption. The present disclosure is not limited as to the number of divisions of the power consumption level.
S102, acquiring a target state of a flash lamp of the camera.
The target states of the flash lamp of the camera include two states, namely a flash lamp on state and a flash lamp off state, so that the flash lamp of the camera can be turned off under the condition that the set condition is met in order to reduce the power consumption of the camera, and the purpose of reducing the power consumption of the camera is achieved.
For example, when the electric quantity of the camera device is too low, in order to ensure the endurance of the camera device, the flash lamp may be turned off directly when photographing. Optionally, in order to obtain a brighter image effect, the defect of turning off the flash can be compensated by increasing the exposure time, so as to ensure the endurance of the camera device.
For example, when the current ambient light in which the camera device is located is sufficiently bright, the flash may be turned off directly when taking a picture in order to reduce the power consumption of the camera. Alternatively, in order to obtain a brighter image effect, the defect of turning off the flash can be compensated by increasing the exposure time.
And S103, responding to the target state as an on state, and adjusting the power of the flash lamp according to the power consumption level.
If the target state of the flash lamp of the camera is in an on state, the power of the flash lamp can be adjusted according to the power consumption level of the camera so as to reduce the power consumption of the flash lamp, thereby reducing the power consumption of the camera.
For example, when the power consumption level of the camera is high, the power of the flash is reduced to reduce the power consumption of the flash, thereby reducing the power consumption of the camera.
According to the method for adjusting the power consumption of the camera, the power consumption level of the camera is obtained; acquiring a target state of a flash lamp of a camera; and adjusting the power of the flash lamp according to the power consumption level in response to the target state being the on state. According to the embodiment of the disclosure, the on or off of the flash lamp is determined according to the power consumption level of the camera, and the power of the flash lamp is further adjusted according to the power consumption level in the on state of the flash lamp, so that the power consumption of the camera can be efficiently adjusted, and the power consumption of the camera is reduced.
Fig. 2 is a flowchart illustrating a method for adjusting power consumption of a camera according to an exemplary embodiment, and as shown in fig. 2, based on the above embodiment, obtaining a target state of a flash of the camera may include the following steps:
s201, obtaining a continuous voyage electric quantity value and/or an environment brightness value of the camera.
And obtaining the current continuous voyage electric quantity value of the camera equipment. The cruising power of the camera device can be directly displayed on a screen, for example, the current cruising power value of the camera is 68%.
And acquiring an environment brightness value of the current environment of the camera. For example, the ambient brightness value of the current environment of the camera is 500lx.
S202, determining a target state of the flash lamp based on the continuous voyage electric quantity value and/or the environment brightness value.
And determining whether the target state of the flash lamp is an on state or an off state according to the obtained continuous voyage electric quantity value and/or the obtained environment brightness value.
For example, a second preset power threshold is preset, for example, the second preset power threshold may be set to 10%, if the obtained endurance power value of the camera device is smaller than or equal to the second preset power threshold, the endurance power value of the camera is considered to be too low, and in order to ensure the endurance capability of the camera device, the target state of the flash lamp is determined to be an off state, that is, the flash lamp is not turned on when the camera takes a photograph. Optionally, the defect of turning off the flash can be compensated by increasing the exposure time, so that the cruising ability of the camera device can be ensured under the condition that a brighter image effect is obtained.
For example, a second preset brightness threshold is preset, if the obtained ambient brightness value of the camera device is greater than or equal to the second preset brightness threshold, the environment where the camera is currently located is considered to be enough to enable the image shot by the camera to have a brighter image effect, and in order to reduce the power consumption value of the camera, the target state of the flash lamp is determined to be an off state, that is, the flash lamp is not turned on when the camera performs shooting. Optionally, the defect of turning off the flash can be compensated by increasing the exposure time, so that the cruising ability of the camera device can be ensured under the condition that a brighter image effect is obtained.
For example, a second preset power threshold is preset, for example, the second preset power threshold may be set to 10%, if the obtained endurance power value of the camera device is greater than the second preset power threshold, the endurance power value of the camera is considered to be sufficient to support the camera to take a picture, and then the target state of the flash lamp is determined to be an on state, that is, the flash lamp is turned on when the camera takes a picture.
For example, a second preset brightness threshold is preset, if the obtained ambient brightness value of the camera device is smaller than the second preset brightness threshold, the current environment of the camera is considered to be darker, the image shot by the camera cannot have a brighter image effect, and the target state of the flash lamp is determined to be an on state, namely the flash lamp is turned on when the camera takes a picture.
According to the method for adjusting the power consumption of the camera, provided by the embodiment of the disclosure, the target state of the flash lamp is determined in a targeted manner by combining the endurance capacity of the camera battery and the ambient brightness around the camera, so that the flash lamp is adjusted according to the target state of the flash lamp, when the endurance capacity value of the camera is too low or the ambient brightness value is high, the flash lamp is directly turned off, the defect that the flash lamp is not turned on for light filling is overcome by increasing the exposure time, the endurance capacity of a user is ensured, the power consumption of the camera can be effectively adjusted, and the power consumption of the camera is reduced.
When it is determined that the flash lamp is in the on state, further adjustment of the flash lamp power in the on state is required, fig. 3 is a flowchart illustrating a method for adjusting the power consumption of the camera according to an exemplary embodiment, and as shown in fig. 3, the method for adjusting the power consumption of the camera according to the embodiment of the disclosure may include the following steps:
s301, acquiring the power consumption level of the camera.
Regarding the implementation manner of step S301, the implementation manner of each embodiment in the present disclosure, for example, the implementation manner of step S101, will not be described herein.
S302, responding to the target state of the camera as an on state, and acquiring a power adjustment value of a flash lamp corresponding to the power consumption level according to the power consumption level.
And determining a power adjustment value of the flash lamp corresponding to the power consumption level of the camera according to the determined power consumption level of the camera.
For example, a correspondence between a power consumption level of the camera and a power adjustment value of a flash lamp of the camera may be preset, for example, when the power consumption level of the camera is divided into three power consumption levels of high power consumption, medium power consumption and low power consumption, the power adjustment value of the corresponding flash lamp may be set to be the first power adjustment value if the power consumption level of the camera is high power consumption; if the power consumption level of the camera is the medium power consumption, the power adjustment value of the corresponding flash lamp is a second power adjustment value; and if the power consumption level of the camera is low power consumption, the power adjustment value of the corresponding flash lamp is a third power adjustment value. The first power adjustment value of the flash lamp is larger than the second power adjustment value, and the second power adjustment value is larger than the third power adjustment value, namely the power consumption level and the power adjustment value of the flash lamp are positively correlated. It is understood that, after determining the power consumption level of the camera, the power adjustment value of the flash corresponding to the power consumption level may be determined according to the power consumption level of the camera. For example, the first power adjustment value of the flash may be set to 80mw, the second power adjustment value of the flash may be set to 40mw, and the third power adjustment value of the flash may be set to 20mw.
The present disclosure is not limited to the number of power consumption levels and is not intended as a limitation of the present disclosure.
S303, adjusting the current power of the flash lamp to a power target value based on the power adjustment value.
And adjusting the current power of the flash lamp according to the determined power adjustment value to obtain a power target value of the flash lamp. For example, if the determined power adjustment value is the second power adjustment value, in order to reduce the power consumption of the camera, the power of the flash is reduced according to the second power adjustment value based on the current power of the flash, and the power value obtained after the reduction is used as the power target value of the flash. For example, if the current power value of the flash lamp is a and the second power adjustment value is b, the power target value of the flash lamp is a-b.
According to the embodiment of the disclosure, according to the power consumption level of the camera, in the on state of the flash lamp, the power adjustment value of the flash lamp corresponding to the power consumption level is further obtained according to the power consumption level, so that the power of the flash lamp is adjusted, the power consumption of the camera can be efficiently adjusted, and the power consumption of the camera is reduced.
In addition to the above-described scheme, when it is determined that the flash is in the on state, further adjustment of the flash power in the on state is required, the following scheme may be adopted. Fig. 4 is a flowchart illustrating a method for adjusting power consumption of a camera according to an exemplary embodiment, and as shown in fig. 4, the method for adjusting power consumption of a camera according to an embodiment of the disclosure may include the following steps:
S401, acquiring an initial power consumption level of a camera.
In the above description, in order to fully consider multiple factors of the camera device, in order to enhance the experience of the user, the power consumption level corresponding to the power consumption value of the camera is not directly used as the final power consumption level, but the power consumption level corresponding to the power consumption value of the camera is used as the initial power consumption level.
Here, it should be noted that, similarly to the above, the correspondence relationship between the initial power consumption level of the camera and the power consumption value of the camera may be preset, for example, dividing different power consumption intervals into three initial levels corresponding to high power consumption, medium power consumption and low power consumption, respectively.
S402, obtaining a continuous voyage electric quantity value and/or an environment brightness value of the camera.
And obtaining the current continuous voyage electric quantity value of the camera equipment. The cruising power of the camera device can be directly displayed on a screen, for example, the current cruising power value of the camera is 68%.
And acquiring an environment brightness value of the current environment of the camera. For example, the ambient brightness value of the current environment of the camera is 500lx.
S403, correcting the initial power consumption level based on the continuous power consumption value and/or the environment brightness value to obtain the final power consumption level of the camera in response to the target state of the camera being the on state.
As an achievable way, the initial power consumption level obtained above may be corrected based on the endurance electric power value, to obtain the final power consumption level of the camera. Two implementation examples of correcting the obtained initial power consumption level based on the continuous power consumption value to obtain the final power consumption level of the camera are given below.
For example, a first preset power threshold is preset, and if the obtained cruising power value is greater than or equal to the first preset power threshold, the obtained initial power consumption level is determined to be a final power consumption level. For example, if the initial power consumption level is high power consumption, the first preset power threshold is set to 50%, and if the obtained cruising power value is 80%, the obtained initial power consumption level is high power consumption and is determined to be the final power consumption level, that is, the final power consumption level is high power consumption.
For example, a first preset power threshold is preset, and if the obtained cruising power value is smaller than the first preset power threshold, the next power consumption level adjacent to the initial power consumption level and smaller than the initial power consumption level is determined as the final power consumption level in consideration of the cruising capability of the device. For example, if the initial power consumption level is high power consumption, the first preset power threshold is set to 50%, and if the obtained cruising power value is 20%, the next power consumption level of the high power consumption is determined to be the final power consumption level, i.e. the middle power consumption is determined to be the final power consumption level. It should be noted that, if the initial power consumption level of the camera is low power consumption, since the low power consumption is already the lowest power consumption level, the low power consumption is not reduced when the continuous power value is smaller than the first preset power threshold.
As another implementation manner, the initial power consumption level may be corrected based on the obtained ambient brightness value, so as to obtain the final power consumption level of the camera. An example of an implementation of correcting the initial power consumption level based on the ambient brightness value to obtain the final power consumption level of the camera is given below.
For example, a first preset brightness threshold is preset, and if the ambient brightness value is smaller than the first preset brightness threshold, the next power consumption level adjacent to the initial power consumption level and smaller than the initial power consumption level is determined as the final power consumption level in consideration of the endurance capability of the device. For example, if the initial power consumption level is high power consumption, if the ambient brightness value is smaller than the first preset brightness threshold value, the next power consumption level of the high power consumption is determined as the final power consumption level, i.e. the middle power consumption is determined as the final power consumption level. It should be noted that, if the initial power consumption level of the camera is low power consumption, since the low power consumption is already the lowest power consumption level, the low power consumption is not reduced when the ambient brightness value is smaller than the first preset brightness threshold.
As another implementation manner, the initial power consumption level may be corrected by combining the obtained cruising electric power value and the environment brightness value, so as to obtain the final power consumption level of the camera. An implementation example of correcting the initial power consumption level to obtain the final power consumption level of the camera by combining the obtained continuous power consumption value and the obtained ambient brightness value is given below.
The initial power consumption level is modified based on the endurance electric quantity value, the modified power consumption level is obtained, and the modified power consumption level is modified again based on the environment brightness value, so that the final power consumption level is obtained. For example, a first preset power threshold and a first preset brightness threshold are preset, if the initial power consumption level is high power consumption, if the obtained cruising power value is smaller than the first preset power threshold, considering the cruising capability of the device, the next power consumption level adjacent to the initial power consumption level and smaller than the initial power consumption level is determined as a corrected power consumption level, after the corrected power consumption level is determined, the environment brightness value is compared with the first preset brightness threshold, and if the environment brightness value is smaller than the first preset brightness threshold, the next power consumption level of the middle power consumption is determined as a final power consumption level, namely, the low power consumption is determined as the final power consumption level.
S404, according to the power consumption level, acquiring a power adjustment value of the flash lamp corresponding to the power consumption level.
And determining a power adjustment value of the flash lamp corresponding to the final power consumption level of the camera according to the determined final power consumption level of the camera.
For example, a correspondence between a final power consumption level of the camera and a power adjustment value of a flash lamp of the camera may be preset, for example, when the power consumption level of the camera is divided into three power consumption levels of high power consumption, medium power consumption and low power consumption, the power adjustment value of the corresponding flash lamp may be set to be the first power adjustment value if the final power consumption level of the camera is high power consumption; if the final power consumption level of the camera is the medium power consumption, the power adjustment value of the corresponding flash lamp is a second power adjustment value; and if the final power consumption level of the camera is low power consumption, the power adjustment value of the corresponding flash lamp is a third power adjustment value. The first power adjustment value of the flash lamp is larger than the second power adjustment value, and the second power adjustment value is larger than the third power adjustment value, namely the power consumption level and the power adjustment value of the flash lamp are positively correlated. It will be appreciated that, after determining the final power consumption level of the camera, the power adjustment value of the flash corresponding to the final power consumption level of the camera may be determined according to the final power consumption level of the camera. For example, the first power adjustment value of the flash may be set to 80mw, the second power adjustment value of the flash may be set to 40mw, and the third power adjustment value of the flash may be set to 20mw.
The present disclosure is not limited to the number of power consumption levels and is not intended as a limitation of the present disclosure.
S405, based on the power adjustment value, the current power of the flash is adjusted to the power target value.
And adjusting the current power of the flash lamp according to the determined power adjustment value to obtain a power target value of the flash lamp. For example, if the determined power adjustment value is the second power adjustment value, in order to reduce the power consumption of the camera, the power of the flash is reduced according to the second power adjustment value based on the current power of the flash, and the power value obtained after the reduction is used as the power target value of the flash. For example, if the current power value of the flash lamp is a and the second power adjustment value is b, the power target value of the flash lamp is a-b.
