detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

first embodiment

The first embodiment of the present invention discloses an image resolution adjustment method. The method is applied to a mobile terminal with a camera. As shown in FIG. 1 , it is a flowchart of an image resolution adjustment method according to a first embodiment of the present invention. The method specifically includes the following steps:

Step S101: Obtain the image captured by the camera and the first resolution of the image.

The camera can be a front camera or a rear camera. Since the camera can be used for taking pictures and taking pictures, the image collected by the camera can be an image in a picture taking mode or an image in a video recording mode.

The first resolution of the image is the default resolution of the image when the camera is turned on.

Step S102: Obtain the current battery level and current temperature of the mobile terminal.

Specifically, the current electric quantity can be obtained by detecting the battery voltage of the mobile terminal. The current temperature can be obtained by detecting the temperature of an NTC (Negative Temperature Coefficient, negative temperature coefficient) resistor on the main board of the mobile terminal.

Step S103: Obtain the second resolution corresponding to the current temperature.

The second resolution is the resolution at a specific temperature, which is preset by the mobile terminal system or the mobile terminal user.

Step S104: Determine whether the current power is lower than a preset threshold.

The preset threshold can be specifically set by the mobile terminal system or the mobile terminal user, and is generally the power level of the low battery warning of the mobile terminal. If the current power of the mobile terminal is higher than the preset threshold, it indicates that the power of the mobile terminal is sufficient; otherwise, the power of the mobile terminal is low and needs to be charged in time.

Step S105: If the current power level is not lower than the preset threshold, compare the first resolution and the second resolution.

If the current power of the mobile terminal is not lower than the preset threshold, the power of the mobile terminal is sufficient. At this time, it is only necessary to consider the influence of the current temperature on the mobile terminal. Therefore, it is only necessary to compare the second resolution corresponding to the current temperature with the first resolution. rate size.

Step S106: If the second resolution is smaller than the first resolution, adjust the resolution of the image to the second resolution.

The second resolution is smaller than the first resolution, and when the resolution of the image is the second resolution, compared with the first resolution, the CPU of the mobile terminal processes less data, which can reduce the power consumption of the mobile terminal. Lower the temperature of the mobile terminal, therefore, adjust the resolution of the image to the second resolution. Otherwise, keep the resolution of the image as the first resolution.

Through the above-mentioned process, the embodiment of the present invention can adjust the resolution of the image according to the temperature of the mobile terminal when the power is sufficient, so as to avoid the large power consumption and high temperature of the mobile terminal.

Preferably, as shown in Figure 2, step S103 specifically includes the following process:

Step S1031: Compare the current temperature with the preset temperature standard.

The preset temperature standard may be multiple temperature ranges or multiple temperature values. For example, when the preset temperature standard is measured in temperature ranges, it is determined which temperature range the current temperature is in.

Step S1032: If the current temperature matches the preset temperature standard, then obtain the second resolution corresponding to the preset temperature standard.

For example, the preset temperature standard is measured by a temperature range, and the current temperature is within the temperature range of a certain preset temperature standard, and the current temperature matches the preset temperature standard. Each preset temperature standard corresponds to a second resolution, and a second resolution can be obtained by matching the current temperature to the temperature standard. The corresponding second resolution can be set by the mobile terminal system or the mobile terminal user.

Preferably, the relationship between the size of the second resolution corresponding to the preset temperature standard and the temperature of the preset temperature standard is negatively correlated, that is, the higher the temperature of the preset temperature standard, the smaller the corresponding second resolution, Therefore, it is beneficial to reduce the power consumption of the mobile terminal, thereby reducing the temperature of the mobile terminal.

Through the above process, the second resolution corresponding to the current temperature can be obtained.

To sum up, in the image resolution adjustment method of the first embodiment of the present invention, when the power of the mobile terminal is sufficient, the relationship between the second resolution corresponding to the current temperature and the default first resolution of the image captured by the camera is compared, if If the second resolution is smaller, the resolution of the image can be adjusted to a smaller second resolution, thereby avoiding that the mobile terminal processes more data and consumes more power because the first resolution of the image is larger. This causes a problem that the temperature of the mobile terminal is high.

second embodiment

The second embodiment of the present invention discloses an image resolution adjustment method. The method is applied to a mobile terminal with a camera. As shown in FIG. 3 , it is a flowchart of an image resolution adjustment method according to a second embodiment of the present invention. The method specifically includes the following steps:

Step S301: Obtain the image captured by the camera and the first resolution of the image.

The camera can be a front camera or a rear camera. Since the camera can be used for taking pictures and taking pictures, the image collected by the camera can be an image in a picture taking mode or an image in a video recording mode.

The first resolution of the image is the default resolution of the image when the camera is turned on.

Step S302: Obtain the current battery level and current temperature of the mobile terminal.

Specifically, the current electric quantity can be obtained by detecting the battery voltage of the mobile terminal. The current temperature can be obtained by detecting the temperature of an NTC (Negative Temperature Coefficient, negative temperature coefficient) resistor on the main board of the mobile terminal.

Step S303: Obtain the second resolution corresponding to the current temperature.

The second resolution is the resolution at a specific temperature, which is preset by the mobile terminal system or the mobile terminal user.

The acquisition of the second resolution corresponding to the current temperature is the same as the steps S1031 to S1032 in the foregoing embodiment, and will not be repeated here.

Step S304: Determine whether the current power is lower than a preset threshold.

The preset threshold can be specifically set by the mobile terminal system or the mobile terminal user, and is generally the power level of the low battery warning of the mobile terminal. If the current power of the mobile terminal is higher than the preset threshold, it indicates that the power of the mobile terminal is sufficient; otherwise, the power of the mobile terminal is low and needs to be charged in time.

Step S305: If the current power level is lower than the preset threshold, obtain a third resolution corresponding to the current power level.

If the current power of the mobile terminal is lower than the preset threshold, the power of the mobile terminal is insufficient. When the mobile terminal is low in power, if it processes more data, the power will decrease faster, and in the case of low power, some mobile terminals will not be able to process some applications that process more data in order to save power. use. Therefore, in the case of low power, not only the influence of the current temperature on the mobile terminal needs to be considered, but also the influence of the current power on the mobile terminal. Therefore, the third resolution corresponding to the current power needs to be obtained.

Step S306: Compare the sizes of the first resolution, the second resolution and the third resolution.

In the case of low power, it is necessary to consider the impact of power on the mobile terminal. Therefore, it is necessary to compare the sizes of the first resolution, the second resolution and the third resolution together.

If the second resolution is the smallest, go to step S307; if the third resolution is the smallest, go to step S308.

Step S307: Adjust the resolution of the image to the second resolution.

If the second resolution is the smallest, it means that when the resolution of the image is the second resolution, the data processed by the mobile terminal is the least, the power consumption is the least, and the temperature of the mobile terminal can be reduced. Therefore, the resolution of the image is adjusted to the second resolution .

Step S308: Adjust the resolution of the image to the third resolution.

If the third resolution is the smallest, it means that when the resolution of the image is the third resolution, the data processed by the mobile terminal is the least, the power consumption is the least, and the temperature of the mobile terminal can be reduced. Therefore, the resolution of the image is adjusted to the third resolution .

It should be understood that if the first resolution is the smallest, the resolution of the image remains unchanged.

Through the above-mentioned process, the second embodiment of the present invention can fully consider the impact of power consumption and temperature on the power consumption and temperature of the mobile terminal when the power is insufficient, and adjust the resolution of the image to the relatively minimum resolution to avoid mobile terminals. The terminal consumes a lot of power and has a high temperature.

Preferably, as shown in Figure 4, step S305 specifically includes the following process:

Step S3051: Compare the current power level with the preset power level standard.

The preset power measurement standard may be multiple power ranges or multiple power values. For example, when the preset electric quantity standard is measured by electric quantity intervals, it is determined which electric quantity interval the current electric quantity is in.

Step S3052: If the current power level matches the preset power level standard, obtain the third resolution corresponding to the preset power level standard.

For example, the preset electric quantity standard is measured by electric quantity interval, then the current electric quantity is within the electric quantity interval of a certain predetermined electric quantity standard, and the current electric quantity matches the preset electric quantity standard. Each preset power level corresponds to a third resolution, and a third resolution can be obtained by matching the current power level to the power level. The corresponding third resolution can be set by the mobile terminal system or the mobile terminal user.

Preferably, the relationship between the size of the third resolution corresponding to the preset power standard and the power level of the preset power standard is negatively correlated, that is, the higher the power of the preset power standard, the smaller the corresponding third resolution, Therefore, it is beneficial to reduce the power consumption of the mobile terminal, thereby reducing the temperature of the mobile terminal.

Through the above process, the third resolution corresponding to the current power level can be obtained.

To sum up, the image resolution adjustment method in the second embodiment of the present invention compares the second resolution corresponding to the current temperature, the third resolution corresponding to the current power consumption, and the default resolution of the image captured by the camera when the battery of the mobile terminal is insufficient. The size relationship of the first resolution, if the second resolution is the smallest, the resolution of the image can be adjusted to the smallest second resolution, or, if the third resolution is the smallest, the resolution of the image can be adjusted to the smallest The third resolution, so as to avoid the problem that the mobile terminal processes more data and consumes more power due to the higher first resolution of the image, resulting in a higher temperature of the mobile terminal.

The mobile terminal may be, but not limited to, a mobile phone, a tablet computer, an MP3/MP4, a smart watch, a smart bracelet, a personal digital assistant (Personal Digital Assistant, PDA), a vehicle-mounted computer, and the like.

As shown in FIG. 5 , it is a structural block diagram of a mobile terminal according to a third embodiment of the present invention. The mobile terminal 500 specifically includes the following structures: a camera 507 , a first acquisition module 501 , a second acquisition module 502 , a third acquisition module 503 , a judgment module 504 , a first comparison module 505 and a first adjustment module 506 .

Wherein, the camera 507 may be a front camera or a rear camera.

The first acquiring module 501 is configured to acquire an image captured by the camera 507 and a first resolution of the image.

Since the camera 507 can be used to take pictures and record videos, the images collected by the camera 507 can be images in the camera mode or images in the camera mode.

The first resolution of the image is the default resolution of the image when the camera 507 is turned on.

The second acquiring module 502 is configured to acquire the current battery level and current temperature of the mobile terminal 500 .

Specifically, the second acquiring module 502 can acquire the current battery capacity by detecting the battery voltage of the mobile terminal 500 . The second obtaining module 502 may obtain the current temperature by detecting the temperature of an NTC (Negative Temperature Coefficient, negative temperature coefficient) resistor on the main board of the mobile terminal 500 .

The third acquiring module 503 is configured to acquire the second resolution corresponding to the current temperature.

The second resolution is the resolution at a specific temperature, which is preset by the mobile terminal 500 system or the mobile terminal 500 user.

The judging module 504 is used to judge whether the current power is lower than a preset threshold.

The preset threshold can be specifically set by the mobile terminal 500 system or the mobile terminal 500 user, and is generally the power level of the low battery warning of the mobile terminal 500 . If the current power of the mobile terminal 500 is higher than the preset threshold, it indicates that the power of the mobile terminal 500 is sufficient; otherwise, the power of the mobile terminal 500 is low and needs to be charged in time.

The first comparison module 505 is used for comparing the size of the first resolution and the second resolution if the current power is not lower than the preset threshold.

If the current power of the mobile terminal 500 is not lower than the preset threshold, the power of the mobile terminal 500 is sufficient. At this time, it is only necessary to consider the influence of the current temperature on the mobile terminal 500. Therefore, it is only necessary to compare the second resolution corresponding to the current temperature with the The size of the first resolution.

The first adjustment module 506 is configured to adjust the resolution of the image to the second resolution if the second resolution is smaller than the first resolution.

The second resolution is smaller than the first resolution, and when the resolution of the image is the second resolution, compared with the first resolution, the CPU of the mobile terminal 500 processes less data, which can make the power consumption of the mobile terminal 500 lower. Small, reduce the temperature of the mobile terminal 500, and therefore adjust the resolution of the image to the second resolution. Otherwise, keep the resolution of the image as the first resolution.

To sum up, the mobile terminal 500 in the third embodiment of the present invention compares the relationship between the second resolution corresponding to the current temperature and the default first resolution of the image captured by the camera 507 when the mobile terminal 500 has sufficient power. If the second resolution is smaller, the resolution of the image can be adjusted to a smaller second resolution, thereby avoiding that the mobile terminal 500 processes more data and consumes more power because the first resolution of the image is larger. , resulting in a problem that the temperature of the mobile terminal 500 is high.

Fourth embodiment

The fourth embodiment of the present invention discloses a mobile terminal, which can realize the details of the method for adjusting the image resolution in the above embodiments, and achieve the same effect. The mobile terminal may be, but not limited to, a mobile phone, a tablet computer, an MP3/MP4, a smart watch, a smart bracelet, a personal digital assistant (Personal Digital Assistant, PDA), a vehicle-mounted computer, and the like.

As shown in FIG. 6 , it is a structural block diagram of a mobile terminal according to a fourth embodiment of the present invention. The mobile terminal 600 specifically includes the following structures: a camera 607 , a first acquisition module 601 , a second acquisition module 602 , a third acquisition module 603 , a judgment module 604 , a first comparison module 605 and a first adjustment module 606 . The functions of the modules mentioned above are the same as those of the modules in the foregoing embodiments, and will not be repeated here.

Preferably, the third acquisition module 603 of the fourth embodiment specifically includes the following structure:

The first comparison sub-module 6031 is used to compare the current temperature with the preset temperature standard.

The preset temperature standard may be multiple temperature ranges or multiple temperature values. For example, when the preset temperature standard is measured in temperature ranges, the first comparison sub-module 6031 determines which temperature range the current temperature is in.

The first acquiring sub-module 6032 is configured to acquire the second resolution corresponding to the preset temperature standard if the current temperature matches the preset temperature standard.

For example, the preset temperature standard is measured by a temperature range, and the current temperature is within the temperature range of a certain preset temperature standard, and the current temperature matches the preset temperature standard. Each preset temperature standard corresponds to a second resolution, and the first obtaining submodule 6032 can obtain a second resolution by matching the current temperature to the temperature standard. The corresponding second resolution can be set by the mobile terminal 600 system or the mobile terminal 600 user.

Preferably, the relationship between the size of the second resolution corresponding to the preset temperature standard and the temperature of the preset temperature standard is negatively correlated, that is, the higher the temperature of the preset temperature standard, the smaller the corresponding second resolution, Therefore, it is beneficial to reduce the power consumption of the mobile terminal 600 , and further reduce the temperature of the mobile terminal 600 .

Through the above-mentioned module design, the second resolution corresponding to the current temperature can be obtained.

Preferably, the mobile terminal 600 of the fourth embodiment also includes:

The fourth obtaining module 608 is configured to acquire the third resolution corresponding to the current power after the step of judging whether the current power is lower than the preset threshold, if the current power is lower than the preset threshold.

If the current power of the mobile terminal 600 is lower than the preset threshold, the power of the mobile terminal 600 is insufficient. Because the mobile terminal 600 is in the case of low power, if the processed data is more, the power will be reduced faster, and in the case of low power, some mobile terminals 600, in order to save power, some applications that process more data will not be available. Therefore, in the case of low power, not only the impact of the current temperature on the mobile terminal 600 needs to be considered, but also the impact of the current power on the mobile terminal 600. Therefore, the fourth acquisition module 608 is required to obtain the third resolution corresponding to the current power.

The second comparison module 609 is configured to compare the sizes of the first resolution, the second resolution and the third resolution.

In the case of low power, the impact of power on the mobile terminal 600 needs to be considered, therefore, the second comparison module 609 is required to compare the sizes of the first resolution, the second resolution and the third resolution together.

The second adjustment module 610 is configured to adjust the resolution of the image to the second resolution if the second resolution is the smallest.

If the second resolution is the smallest, it means that when the resolution of the image is the second resolution, the data processed by the mobile terminal 600 is the least, the power consumption is the smallest, and the temperature of the mobile terminal 600 can be reduced. Therefore, the second adjustment module 610 adjusts the image resolution. The resolution is the second resolution.

The third adjustment module 611 is configured to adjust the resolution of the image to the third resolution if the third resolution is the smallest.

If the third resolution is the smallest, it means that when the resolution of the image is the third resolution, the data processed by the mobile terminal 600 is the least, the power consumption is the smallest, and the temperature of the mobile terminal 600 can be reduced. Therefore, the third adjustment module 611 adjusts the image resolution. The resolution is the third resolution.

It should be understood that if the first resolution is the smallest, the resolution of the image remains unchanged.

Preferably, the fourth obtaining module 608 includes:

The second comparison sub-module 6081 is used to compare the current electric quantity with the preset electric quantity standard.

The preset power measurement standard may be multiple power ranges or multiple power values. For example, when the preset electric quantity standard is measured by electric quantity intervals, the second comparison sub-module 6081 judges which electric quantity interval the current electric quantity is in.

The second obtaining sub-module 6082 is configured to obtain the third resolution corresponding to the preset electric quantity standard if the current electric quantity matches the preset electric quantity standard.

For example, the preset electric quantity standard is measured by electric quantity interval, then the current electric quantity is within the electric quantity interval of a certain predetermined electric quantity standard, and the current electric quantity matches the preset electric quantity standard. Each preset power level corresponds to a third resolution, and the second obtaining submodule 6082 can obtain a third resolution by matching the current power level with the power level. The corresponding third resolution can be set by the mobile terminal 600 system or the mobile terminal 600 user.

Preferably, the relationship between the size of the third resolution corresponding to the preset power standard and the power level of the preset power standard is negatively correlated, that is, the higher the power of the preset power standard, the smaller the corresponding third resolution, Therefore, it is beneficial to reduce the power consumption of the mobile terminal 600 , and further reduce the temperature of the mobile terminal 600 .

Through the above-mentioned module design, the third resolution corresponding to the current power level can be obtained.

To sum up, the mobile terminal 600 of the fourth embodiment of the present invention can not only compare the size relationship between the second resolution corresponding to the current temperature and the default first resolution of the image captured by the camera 607 when the battery is sufficient, if the second If the second resolution is smaller, you can adjust the resolution of the image to a smaller second resolution; you can also compare the second resolution corresponding to the current temperature and the third resolution corresponding to the current power when the battery is insufficient. The size relationship with the default first resolution of the image acquired by the camera 607, if the second resolution is the smallest, the resolution of the image can be adjusted to the smallest second resolution, or, if the third resolution is the smallest, then the The resolution of the image is adjusted to the smallest third resolution; thereby avoiding that the first resolution of the image is relatively large, the data processed by the mobile terminal 600 is large, the power consumption is large, and the temperature of the mobile terminal 600 is relatively high. question.
