Detailed Description
In order to solve the technical problems that the supervision mode adopted by the prior art for preventing candid shooting is too complicated and has poor effect, the invention provides a shooting function control method and a shooting function control device, and the invention is further described in detail with reference to the attached drawings and the embodiment. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
The inventor considers that if the camera shooting function of the terminal is completely closed in a special place, the problem of shooting or camera shooting can be effectively avoided.
Therefore, the appointed light source can be identified through the terminal camera, meanwhile, after the light source intensity reaches a certain threshold value, the terminal is triggered to automatically disable the shooting function, and a user is prompted to 'the shooting is forbidden in the area', the shooting terminal cannot be used in a specific place or special objects are shot, and therefore management is simplified.
As shown in fig. 1, there is provided a photographing function control method in this example, which may include the steps of:
step 101: determining whether a preset light wave is identified;
that is, a light source may be preset, in order not to affect normal viewing, invisible light may be selected as a preset light source, and when the terminal camera device is turned on, a preset light wave emitted by the light source may enter through a lens of the camera terminal. Whether the preset light wave exists or not can be determined in a certain identification mode.
Step 102: if so, determining whether the light wave intensity of the preset light wave is greater than a preset threshold value;
further, after the light wave is identified, because there are many waves in the natural light, in order to avoid the hardness of the light wave in the natural light, the threshold value of the light wave emitted by the light source and the intensity of the light wave can be judged through the preset parameter, whether the intensity of the light wave exceeds the threshold value is determined, and if the intensity of the light wave exceeds the threshold value, the light wave is determined to be detected.
Step 103: and if the current value is larger than the preset value, controlling the shooting function of the terminal to be in a closed state.
After the determination, the photographing function may be controlled to be in an off state, thereby achieving the purpose of area prohibition photographing. In order to make the user aware of the prompt, "the area prohibited from shooting" may be displayed on the terminal display interface to remind the user.
In order to realize the control of the camera shooting, the control can be carried out in a plug-in mode, namely, a plug-in is loaded for the terminal, the plug-in is used for activating the operation of determining whether the preset light wave is identified, and the preset light wave and the preset threshold value are preset in the plug-in.
Specifically, the terminal may load the plug-in, but not limited to, in one of the following ways:
1) loading the plug-in by scanning the two-dimensional code;
2) automatically loading the plug-in when the AP is connected;
3) and automatically loading the plug-in through NFC induction.
For example, the mobile phone supports the NFC function, when the mobile phone passes through a place entrance, NFC is automatically induced, a terminal background automatically downloads a plug-in, the function is activated, and prefabricated parameters are loaded; when the terminal passes through a place outlet, NFC automatic induction is carried out, and the plug-in is automatically deleted, so that the deactivation function and the deletion of the prefabricated parameters are realized.
The preset light wave may include: the first light wave and the second light wave can preset two or more than two preset light waves. Accordingly, determining whether the first and second light waves are identified; determining whether the light wave intensity of the first light wave is greater than a first light wave threshold value and whether the light wave intensity of the second light wave is greater than a second light wave threshold value; and under the condition that the light wave intensity of the first light wave is determined to be greater than the first light wave threshold value, and the light wave intensity of the second light wave is determined to be greater than the second light wave threshold value, controlling the shooting function of the terminal to be in a closed state.
In order to further improve the accuracy of the determination, a preset frequency may be set, that is, it is determined whether the frequency of the preset light wave is the preset frequency, and if so, it is determined whether the light wave intensity of the preset light wave is greater than a preset threshold.
When the light wave intensity and the frequency of the light wave are judged, the identified preset light wave can be converted into an electric signal; converting the electrical signal into a digital signal; and then determining whether the light wave intensity of the preset light wave is greater than a preset threshold value according to the digital signal.
Specifically, the wavelength and light source intensity parameters of the invisible light source can be prefabricated in different places according to the characteristics of the invisible light source, the function is activated and the prefabricated parameters are loaded through special means, for example:
1) scanning the two-dimensional code in and out of a place, automatically loading a plug-in, activating/deactivating the function and loading/deleting the prefabricated parameters;
2) connecting the AP of a place through a terminal, automatically loading a plug-in after the AP is successfully connected, activating the function and loading the prefabricated parameters; the terminal disconnects the site AP, reconnects a new AP (non-site AP), and automatically deletes the plug-in when the site AP cannot be detected, thereby realizing the deactivation function and deleting the prefabricated parameters;
3) the mobile phone supports an NFC function, when the mobile phone passes through a place entrance, NFC is automatically induced, a terminal background automatically downloads a plug-in, the function is activated, and prefabricated parameters are loaded; when the terminal passes through a place outlet, NFC automatic induction is carried out, and the plug-in is automatically deleted, so that the deactivation function and the deletion of the prefabricated parameters are realized.
Based on the same inventive concept, the embodiment of the present invention further provides a shooting function control apparatus, as described in the following embodiments. Because the principle of the shooting function control device for solving the problems is similar to the shooting function control method, the shooting function control device can be implemented by the shooting function control method, and repeated parts are not described again. As used hereinafter, the term "unit" or "module" may be a combination of software and/or hardware that implements a predetermined function. Although the means described in the embodiments below are preferably implemented in software, an implementation in hardware, or a combination of software and hardware is also possible and contemplated. Fig. 2 is a block diagram of a structure of a photographing function control apparatus according to an embodiment of the present invention, as shown in fig. 2, which may include: a first determination module 201, a second determination module 202, and a control module 203, the structure of which will be described below.
A first determining module 201, configured to determine whether a preset light wave is identified;
the second determining module 202 may be configured to determine whether the light wave intensity of the preset light wave is greater than a preset threshold value in the case of determining whether the preset light wave is reached;
the control module 203 may be configured to control the shooting function of the terminal to be in a closed state when it is determined that the light wave intensity of the preset light wave is greater than the preset threshold.
In one embodiment, the photographing function control apparatus may further include: the loading module is used for controlling the terminal to load a plug-in unit before detecting whether the preset light wave exists, wherein the plug-in unit is used for activating and determining whether the operation of the preset light wave is identified, and the preset light wave and the preset threshold value are preset in the plug-in unit.
In one embodiment, the loading module may be specifically configured to load the plug-in one of the following ways: loading the plug-in by scanning the two-dimensional code; automatically loading the plug-in when the AP is connected; or, the plug-in is automatically loaded through NFC induction.
In one embodiment, the second determining module 202 may include: a first determining unit for determining whether a frequency of the preset optical wave is a preset frequency; a second determining unit, configured to determine whether the light wave intensity of the preset light wave is greater than a preset threshold value, if it is determined that the frequency of the preset light wave is the preset frequency.
In one embodiment, the second determining module 202 may include: the first conversion unit is used for converting the identified preset light wave into an electric signal; a second conversion unit for converting the electric signal into a digital signal; and the third determining unit is used for determining whether the light wave intensity of the preset light wave is greater than a preset threshold value according to the digital signal.
The control method is described below with reference to an embodiment, but it should be noted that the embodiment is only for better describing the present invention and is not to be construed as limiting the present invention.
In this example, an invisible light source is preset, and a set of light wave and light intensity detection parameter plug-in is prefabricated, and the terminal can be automatically loaded. When the camera terminal is started, light waves emitted by the light source enter through a lens of the camera terminal, the judging device judges whether the light waves emitted by the corresponding light source and the light intensity of the light waves are compared with a threshold value set by a threshold value through the loaded prefabricated parameters, and the terminal automatically triggers the start or the disable of the camera function.
Light is an electromagnetic wave whose wavelength range is from a few nanometers (10-9 m at 1 nm) to about 1 millimeter (mm). Visible light is only one part of the visible light, namely visible light, the wavelength range of the visible light is 380 nm-780 nm, the visible light is divided into red light, orange light, yellow light, green light, cyan light, blue light and purple light from long to short, the visible light with the wavelength shorter than that of the purple light is called ultraviolet light, and the visible light with the wavelength longer than that of the red light is called infrared light. In this example, invisible light may be employed as the specified light source.
Light source: emitting a judging light wave, for example: 300nm ultraviolet light, 900nm infrared light, specifically choose which kind of wavelength's light source to choose for use, can select according to actual scene, and this application does not limit this.
The light source equipment emits light waves which can be judged, when the terminal enters a light wave coverage area, the terminal function is started, and the preset wavelength and the threshold value a threshold value parameter are loaded successfully. When the terminal camera is opened, the light wave can be judged to enter the terminal camera and reach the sensor through the optical filter. The sensor identifies that the light wave can be judged, and converts the light signal into a corresponding electric signal; the electric Signal is converted into a Digital Signal through an A/D Digital-to-analog converter, a Digital Signal Processing (DSP) chip judges the light wave intensity, and when the light wave intensity is larger than a threshold value a, a terminal CPU automatically disables the shooting function. And displays "this area is prohibited from taking a picture" on the screen; if the value is less than or equal to the threshold value a, no operation is performed.
Namely, the light wave which can be judged is received, and if the light intensity a of the light wave which can be judged is greater than the threshold value a, the terminal automatically forbids the photographing function.
When the terminal leaves the light wave coverage area and the terminal camera is opened, the light wave capable of being judged also exists in the natural light, and when the light wave capable of being judged in the natural light enters the terminal camera, the light wave reaches the sensor through the optical filter. The sensor identifies light waves and converts light signals into corresponding electric signals; the electric signal is converted into a digital signal through an A/D digital-analog converter, the digital processing chip DSP judges the light wave intensity, and when the light wave intensity is larger than a threshold value a, the terminal CPU disables the shooting function.
That is, the terminal receives the light wave which can be judged in the natural light, and if the light intensity a of the light wave can be judged to be < a threshold, the terminal does not prohibit the photographing function.
The following description of the embodiments is made in connection with two specific examples of user applications.
Example 1
As shown in fig. 3, when the terminal function is turned on and the threshold parameter of the pre-defined wavelength and light intensity threshold value a is successfully loaded, the following steps are performed:
step 1: arranging light source equipment beside the article prohibited from taking a picture, wherein the light source equipment emits light with a light intensity of a 1;
step 2: the terminal starts a camera shooting function, shoots objects, and light waves enter the camera through the filter;
and step 3: the camera sensor identifies light which can judge light waves, otherwise, the CPU does not carry out any operation on the camera function;
and 4, step 4: converting the electric signal into a digital signal through A/D digital-to-analog conversion;
and 5: the DSP analyzes the digital signal and calculates to obtain the light wave intensity a 1;
step 6: the DSP compares the light intensity a threshold value and judges the magnitude relation between the light wave intensity a1 and the a threshold value;
and 7: if the light wave intensity a1 is judged to be larger than the a threshold value, the CPU indicates that the shooting function is stopped, and displays a prompt dialog box 'the shooting is forbidden in the area';
and 8: if the light wave intensity a1 can be judged to be < a threshold, the CPU does not terminate the shooting function.
Example 2
As shown in fig. 4, a group of invisible light sources is designated, whether the terminal shooting function is prohibited or not is judged by identifying whether the wavelength and the light intensity of the light sources are greater than a threshold value, and the colleague adds judgment conditions and judges based on 2 groups of judging light waves.
The judgment conditions are as follows:
1) the light wave 1 can be judged;
2) the light wave 2 can be judged;
3) the light intensity a1 of the light wave 1 is judged to be greater than a threshold value;
4) the light intensity a2 of the light wave 2 is judged to be greater than a threshold value;
when the above 4 conditions are simultaneously satisfied, the terminal automatically prohibits the shooting function, so that the accuracy of judgment is increased, and the flow chart is as follows:
example 3
As shown in fig. 5, a group of invisible light sources is specified, and by identifying whether the wavelength and the light intensity of the light sources are greater than a threshold value, a determination condition is added, specifically, the light emitting frequency f1 of the light sources is added for determination on the basis of determining whether the terminal shooting function is prohibited.
The judgment conditions are as follows:
1) the light wave 1 can be judged;
2) the light source emits light wave 1 with frequency f 1;
3) the light intensity a1 of the light wave 1 is judged to be greater than a threshold value;
if the above 3 conditions are simultaneously satisfied, the terminal automatically prohibits the shooting function, thereby increasing the accuracy of the judgment.
In the embodiment of the invention, on the basis of the existing camera, the light source emission intensity is calculated by receiving and processing the special light source, and compared with the prefabricated light wave wavelength and the light wave intensity parameter, the control terminal controls whether the shooting function is forbidden, so that the problem of illegal shooting of the forbidden objects is effectively prevented.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, and the scope of the invention should not be limited to the embodiments described above.
