Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Today, people and various terminal devices such as mobile phones, tablets, computers and televisions are surrounded by people and various terminal devices such as videos and videos in life. Terminal devices have slowly penetrated into the corners of people's lives. Among them, mobile terminal devices such as mobile phones are more essential for life of people. With the advance of technology, mobile terminal devices have no longer been used as mobile portable telephones or short message displays, and have become important tools for people to carry with them, such as communication devices, information centers, memories, navigators, clocks, perpetual calendars, cameras and the like. Particularly, with the rapid development of the digital technology, the camera of the mobile terminal has higher and higher photographing pixels, stronger and stronger photographing function, and better photographed image quality. The portable digital camera is convenient to carry, use, have high image quality and is convenient to show and share, and the middle-low grade digital camera is almost driven out of the market in short years, so that the portable digital camera becomes a preferred choice for photographing and persisting in daily life and during traveling, and provides convenience for people to record and share events nearby at any time. Because the camera function of the mobile terminal is widely used, the speed of saving photos by the mobile terminal is very quick, the photos often occupy a large storage space of the mobile terminal, the storage space of the mobile terminal is limited, and the normal use of the mobile terminal is affected when a large amount of storage space is occupied. It is necessary to control the speed of saving photos and reduce the occupied storage space of the mobile terminal. Among the photos accumulated by the mobile terminal, many photos are redundant photos taken during shooting, and the redundant photos occupy more storage space, so that the mobile terminal memory is excessively occupied inefficiently. How to reduce these redundant photos and further reduce the invalid occupation of the memory space of the mobile terminal becomes a problem to be solved.
In order to solve the problems in the prior art, the embodiment provides a method for reducing redundant photos of a mobile terminal, and by the method of the embodiment, a user does not need to manually search and delete the redundant photos and the like on the mobile terminal, so that convenience is provided for the user. In specific implementation, in this embodiment, first, when the mobile terminal takes a picture, a change of the taken picture is detected, when the taken picture does not change within a set time, power consumption data is acquired at set time intervals, when the power consumption data changes slightly within a set time period, a first threshold and a second threshold are set according to the acquired power consumption data, the power consumption data of the mobile terminal is monitored, when the power consumption data of the mobile terminal changes slightly, that is, the power consumption data is between the first threshold and the second threshold, the picture taking is resumed, and when the power consumption data of the mobile terminal changes greatly, that is, the power consumption data is greater than the first threshold or less than the second threshold, the picture taking is temporarily prohibited, so that redundant pictures are reduced.
Therefore, the method and the device have the advantages that the change of the shot image is detected when the mobile terminal shoots, the power consumption data is obtained at set time intervals, the first threshold value and the second threshold value are set according to the power consumption data, and whether the shooting is temporarily prohibited or resumed is determined according to the monitored power consumption data of the mobile terminal, so that redundant photos are automatically reduced, the redundant photos do not need to be manually searched and deleted, and convenience is brought to the use of a user.
For example, in home life, mobile terminals (smart phones, tablet computers, and the like) purchased by users are often used for shooting interesting or meaningful things in daily life, and when traveling outside, a large number of photos of landscape and people are shot, and in the shooting process, a large number of redundant photos are often shot, and are accumulated in the future, and occupy a large amount of storage space.
Exemplary method
The method for reducing redundant photos of a mobile terminal in this embodiment may be applied to a mobile terminal device, and specifically as shown in fig. 1, the method for reducing redundant photos of a mobile terminal includes the following steps:
and S100, when the mobile terminal takes a picture, the mobile terminal system detects the change of the shot image.
In order to enable redundant photos of the mobile terminal to be automatically reduced without manually searching and deleting the redundant photos in the memory by a user, in the embodiment, when the user uses the mobile terminal to shoot and reduce the redundant photos of the mobile terminal, the mobile terminal system is firstly required to detect the change of the shot images. In the embodiment, the mobile terminal system detects the change of the shot image when the mobile terminal takes a picture. When the mobile terminal takes a picture, the mobile terminal system detects the change of the taken picture and specifically comprises the following steps:
the mobile terminal system sets a data difference threshold value of pixels between the shot images;
the mobile terminal system detects continuous frame images, selects pixels of fixed pixel points from the continuous frame images for comparison, and judges whether the shot images change or not according to the relationship between the data difference values of the pixels and the data difference threshold.
In this embodiment, when the mobile terminal takes a picture, the mobile terminal system detects a change of the taken picture, for example: when the mobile terminal takes a picture, the mobile terminal system detects continuous frame images, selects pixels of fixed pixel points from the continuous frame images for comparison, and if the data difference value of the pixels of the continuous frame images is smaller than a set data difference threshold value, the images are considered to be unchanged.
Specifically, first, in the mobile terminal system, a data difference threshold is set for the pixel difference between images, and when the pixel difference between the captured images is lower than the set data difference threshold, it is considered that the captured images are not changed. Because the image quality of the shot image is fine and the pixel is high, if the pixel difference of the whole image is compared comprehensively, the calculation data amount of the system is large, and the requirement on equipment hardware is high. In the embodiment, there is no method for comparing the pixel difference of the whole image in a sampling manner. In specific implementation, in order to reduce the calculation amount of the system, increase the operation speed, and reduce the requirement on the hardware of the device, only a part of fixed pixel points need to be selected for pixel comparison, for example: one pixel point is selected for pixel comparison every 100 pixels, so that the calculation data amount during pixel comparison can be greatly reduced, the requirement on equipment hardware is reduced, the mobile terminal system can quickly perform pixel comparison, and meanwhile, the correctness of the comparison result is not influenced.
And step S200, when the shot image is not changed within the set time, the mobile terminal system acquires the power consumption data of the mobile terminal at set time intervals.
In this embodiment, a power consumption detection function is first set in the mobile terminal, and is used to monitor power consumption data of the mobile terminal.
It is known that when a mobile terminal system is located at different points on the earth, power consumption data of the mobile terminal are different. Based on such a principle, when the image has not changed within the set time, it means that the mobile terminal is almost in a static state, in which the mobile terminal system monitors and acquires the power consumption data of the mobile terminal at set time intervals, generally, in this embodiment, the set time interval is 2 seconds.
Specifically, in this embodiment, for the power consumption monitoring mode of the mobile terminal, this embodiment provides two different embodiments, and the specific steps of the two modes include:
the first implementation mode is that a resistor is connected in series with the output end of the battery of the mobile terminal, the resistance value of the resistor can adopt a smaller resistor, the voltage difference between the two ends of the resistor is obtained, and the power consumption data of the mobile terminal is obtained after conversion is performed by a mathematical method in the prior art, that is, the power consumption of the mobile terminal monitored by the mobile terminal system is actually obtained by monitoring the voltage difference between the two ends of the smaller resistor connected in series with the output end of the battery of the mobile terminal.
The second implementation mode is that a resistor is connected in series at the baseband power supply position of the mobile terminal, the resistance value of the resistor can adopt a smaller resistor, the voltage difference between two ends of the resistor is obtained, and the power consumption data of the mobile terminal is obtained after conversion is carried out through a mathematical method in the prior art. Different from the first embodiment, power is obtained from the output end of the battery, but the voltage difference between two ends of the resistor is obtained by connecting a smaller resistor in series, and power consumption data of the mobile terminal is obtained after conversion is carried out through a mathematical method. The advantage of this approach is that it can still be implemented in case the user uses a network (e.g., WIFI), etc.
Step S300, when the obtained power consumption data changes slightly in a set time period, obtaining current power consumption data, and setting a first threshold value and a second threshold value according to the obtained current power consumption data.
Considering the change of the power consumption data of the mobile terminal, an index serving as a reference is required, and a threshold value is required to be set, so that the power consumption data of the mobile terminal needs to be acquired when the power consumption change of the mobile terminal is minimum, namely when the mobile terminal is almost still, the power consumption of the mobile terminal is acquired, and the threshold value is set according to the acquired power consumption value. In this embodiment, two threshold values, i.e., a first threshold value and a second threshold value, are set as required.
Specifically, when a shot image is not changed within a set time, the mobile terminal system acquires power consumption data of the mobile terminal at set time intervals, and when the acquired power consumption data changes slightly within a set time period, the mobile terminal system acquires the power consumption data of the current mobile terminal;
setting a first threshold value: setting a first threshold value by 1.1 times of the current power consumption data according to the acquired current power consumption data of the mobile terminal;
setting a second threshold value: setting a second threshold value by 0.9 times of the current power consumption data according to the acquired current power consumption data of the mobile terminal;
the power consumption data is set in a set time period, which is set to 60 seconds in the present embodiment.
Step S400, the mobile terminal system monitors power consumption data of the mobile terminal, and when the power consumption data is larger than the first threshold value or smaller than the second threshold value, photographing is forbidden; and when the power consumption data is between the first threshold value and the second threshold value, the photographing is resumed.
In this embodiment, the mobile terminal system continuously monitors the power consumption change of the mobile terminal, and acquires the power consumption data of the mobile terminal at regular intervals, in this embodiment, the mobile terminal system samples the power consumption data of the mobile terminal at intervals of 2 seconds, and compares the sampled power consumption data with the set first threshold value and the set second threshold value.
Specifically, the mobile terminal system monitors the power consumption of the mobile terminal, acquires power consumption data of the mobile terminal every 2 seconds, compares the power consumption data with a set first threshold value and a set second threshold value respectively, and generates an interrupt signal when the power consumption data of the mobile terminal is greater than the first threshold value; an interrupt signal is also generated when the power consumption data of the mobile terminal is less than the second threshold value. In this embodiment, the interrupt signal is a level signal that changes from low level to high level for a detection pin, or changes from high level to low level for a detection pin. The central processing unit in the mobile terminal is connected with an interruption pin for power consumption monitoring, the detection pin for the interruption pin for power consumption monitoring is changed from a low level to a high level, or is changed from the high level to a level signal of the low level, and the central processing unit makes a corresponding response according to the level of the detection pin.
The mobile terminal system monitors the power consumption of the mobile terminal, compares the power consumption data of the mobile terminal acquired every 2 seconds with a set first threshold value and a set second threshold value respectively, generates an interrupt signal when the power consumption data of the mobile terminal is larger than the first threshold value or smaller than the second threshold value, and temporarily prohibits the mobile terminal from taking pictures according to the interrupt signal. And when the mobile terminal system monitors the power consumption of the mobile terminal, comparing the power consumption data of the mobile terminal acquired every 2 seconds with a set first threshold value and a set second threshold value respectively, and when the power consumption data is smaller than the first threshold value and larger than the second threshold value, namely the power consumption data is between the first threshold value and the second threshold value, at the moment, the mobile terminal system does not generate an interrupt signal, and the mobile terminal system resumes photographing.
Specifically, it is known that when a camera of a mobile terminal device is used to photograph a picture, power consumption data of the mobile terminal differs for each different point on the earth. When the acquired power consumption data is between the first threshold and the second threshold, that is, the power consumption data is smaller than the first threshold and larger than the second threshold, it indicates that the power consumption data of the mobile terminal at this time changes very slightly, and the mobile terminal device is in a static state, that is, the user does not use the mobile terminal temporarily, and the user can use the mobile terminal to resume taking pictures.
In summary, the present embodiment provides a method for reducing redundant photos of a mobile terminal, where the change of a shot image is detected when the mobile terminal takes a photo, when the shot image does not change within a set time, power consumption data is obtained at set time intervals, a first threshold and a second threshold are set according to the power consumption data, the power consumption data of the mobile terminal is monitored, the power consumption data is compared with the first threshold and the second threshold, and whether the mobile terminal takes a photo or prohibits a photo according to a comparison result, so that redundant photos are reduced, a problem that precious storage space in the mobile terminal is occupied by a large number of redundant photos is avoided, and user experience is greatly improved.
Exemplary device
As shown in fig. 2, an embodiment of the present invention provides an apparatus for reducing redundant photos of a mobile terminal, the apparatus including: the system comprises an image detection module 10, a power consumption data acquisition module 20, a power consumption data monitoring module 30 and a photographing control module 40.
Specifically, the image detection module 10 is configured to detect a change of a shot image by the mobile terminal system when the mobile terminal takes a picture; a power consumption data obtaining module 20, configured to obtain, by the mobile terminal system, power consumption data of the mobile terminal at set time intervals; the power consumption data monitoring module 30 is configured to set a first threshold value and a second threshold value according to the acquired power consumption data, compare the first threshold value and the second threshold value with the acquired current power consumption data, generate an interrupt signal, and send an instruction for prohibiting photographing; the photographing control module 40 is configured to detect power consumption data of the mobile terminal detected by the power consumption detection module, and prohibit photographing when the power consumption data is greater than the first threshold or smaller than the second threshold; and when the power consumption data is between the first threshold value and the second threshold value, the photographing is resumed, and whether the camera action of the mobile terminal is photographing or is temporarily prohibited can be controlled.
In one implementation manner, when the image detection module 10 uses the mobile terminal device to take a picture, the mobile terminal first reads the continuous frame images and detects the continuous frame images;
specifically, pixels of fixed points are selected from the read continuous frame images for comparison, and the change size of the continuous frame images is confirmed; only when the pixel difference of the images of the successive frames is sufficiently small, the mobile terminal proceeds to next acquire power consumption data of the mobile terminal. In this embodiment, the mobile terminal system is provided with a data difference threshold value in advance, and if the pixel difference of the images of consecutive frames is sufficiently small, the data difference threshold value is compared with the pixel difference of the images of consecutive frames, and if the pixel difference of the images of consecutive frames is smaller than the data difference threshold value, the mobile terminal system assumes that the images of consecutive frames have not changed.
In one implementation, the power consumption data acquiring module 20 performs the operation of acquiring the power consumption data of the mobile terminal at set time intervals when it is determined that the consecutive frame images do not change, where the set time interval is 2 seconds.
In this implementation, there are two implementation means for power consumption data acquisition:
the first implementation means is to serially connect a resistor at the output end of the battery of the mobile terminal, the resistance value of the resistor can adopt a smaller resistance value, the voltage difference between the two ends of the resistor is obtained, and the power consumption data of the mobile terminal is obtained after conversion is carried out by a mathematical method in the prior art. That is, the power consumption of the mobile terminal system is actually obtained by monitoring the voltage difference across a small resistor connected in series with the output terminal of the battery of the mobile terminal.
The second implementation mode is that a resistor is connected in series at the baseband power supply position of the mobile terminal, the resistance value of the resistor can adopt a smaller resistor, the voltage difference between two ends of the resistor is obtained, and the power consumption data of the mobile terminal is obtained after conversion is carried out through a mathematical method in the prior art. Different from the first embodiment, power is obtained from the output end of the battery, but the voltage difference between two ends of the resistor is obtained by connecting a smaller resistor in series, and power consumption data of the mobile terminal is obtained after conversion is carried out through a mathematical method. The advantage of this approach is that it can still be implemented in case the user uses a network (e.g., WIFI), etc.
In one implementation, the power consumption data monitoring module 30 includes:
firstly, a first threshold value and a second threshold value are set according to the acquired power consumption data. Only when the shot image is not changed within the set time, the mobile terminal system monitors the power consumption data of the mobile terminal, and when the power consumption data of the mobile terminal is kept stable within a specified time period (set to 60 seconds in the implementation mode) and fluctuates slightly, the power consumption data of the mobile terminal is sampled, and a first threshold value and a second threshold value are set according to the power consumption data.
In the implementation mode, the mobile terminal system continuously monitors the power consumption data of the mobile terminal, acquires the power consumption data of one mobile terminal every 2 seconds, compares the acquired power consumption data with the first threshold value and the second threshold value, and sends out a command of forbidding photographing or not.
In one implementation, the photographing control module 40 includes:
when the acquired power consumption data is compared with the first threshold value and the second threshold value, and the power consumption data is larger than the first threshold value or smaller than the second threshold value, the mobile terminal system generates an interrupt signal, and the mobile terminal temporarily prohibits photographing. When the mobile terminal is ready to take a picture, the mobile terminal system detects the interrupt signal, activates the mobile terminal picture taking function and resumes the picture taking.
And when the acquired power consumption data is compared with the first threshold value and the second threshold value, the power consumption data is smaller than the first threshold value and larger than the second threshold value, the mobile terminal is in a static state, and when the mobile terminal is ready to take a picture, the picture taking is resumed.
