Detailed ways

The photographing parameter adjustment method of the embodiment of the present invention is applied to photographing by a smart terminal. For example, when a user takes a photograph with his/her own smartphone, the photographing parameter adjustment method can be used.

First of all, before explaining the method, briefly describe the basic principle of taking pictures with the camera: usually, the faster the moving speed of the target object to be photographed, the faster the corresponding shutter speed; and the way to increase the shutter speed, In the camera application of smart terminals, it can be realized by increasing the ISO value. Under the same conditions, ISO (ISO is the abbreviation of International Organization for Standardization, which is the English abbreviation of the International Sensitivity of sensor) to brightness The Chinese name of ISO can be understood as: the higher the value of sensitivity, the faster the corresponding shutter speed; the lower the ISO value, the slower the corresponding shutter speed. Therefore, you can obtain a fast shutter speed by increasing the ISO value to capture fast-moving subjects.

The process of how to improve the ISO value in the photographing parameter adjustment method of the embodiment of the present invention will be described in detail as follows, as shown in FIG. 1 , including:

101. It is detected that the camera mode is started, and the ISO adjustment trigger operation information is received in the camera mode;

102. Increase the ISO value of the camera from the current first value to a second value, so that the camera takes pictures according to the second value.

Specifically, in step 101, the smart terminal detects that the camera mode is activated, and the camera mode activation means that, for example, the user uses his smart phone and clicks the "camera" icon on the mobile phone, and the camera mode corresponding to the icon is activated. , a mode that is taking pictures will appear on the user's phone screen.

In this embodiment, the smart terminal may also receive the ISO adjustment trigger operation information in the photographing mode. Wherein, the function of the ISO adjustment trigger operation information is that as long as the smart terminal detects this information, it indicates that the value of ISO needs to be increased (ISO is one of the parameters when the smart terminal takes pictures), and the subsequent step 102 is executed. Therefore, this information is equivalent to an instruction information to adjust the ISO value, and is information indicating to increase the ISO value.

An optional form of the ISO adjustment trigger operation information is enumerated as follows: the information may be, for example, sliding operation information on the screen. Referring to the example in FIG. 2 , FIG. 2 shows that in the camera mode of the smartphone, the user performs a sliding operation on the screen of the smartphone. The sliding operation can be detected by the sensor on the screen of the mobile phone, and the information is transmitted to the control layer of the smart phone. An ISO adjustment trigger operation message was detected. Of course, in actual implementation, the operation that can trigger the adjustment of the ISO value is not necessarily the above-mentioned sliding operation on the screen, but also other operation forms, which can be flexibly set.

Even if it is a sliding operation, you can define a specific type of sliding operation as the trigger operation information for ISO adjustment. For example, you can set a sliding operation in a specific area on the mobile phone screen as the trigger operation information, or set a sliding operation in a specific direction as the trigger operation Information, etc., will not be listed in detail. Figure 3 also illustrates an example of a user performing a sliding operation on the mobile phone screen. In Figure 3, after the user enters the preview mode, when the user clicks the "photograph" icon to take a photo, it is equivalent to the photo icon being selected and clicked, indicating that The user wants to take pictures of the scene. At this time, the user presses and holds the photo icon and slides it directly; when the smart terminal detects the above-mentioned sliding operation information when the photo icon is selected, it adjusts the ISO value according to the sliding moment, and takes a picture immediately , which is equivalent to quickly adjusting the shooting and ISO value. In the example in Figure 2, the user is still in the preview mode and has not yet determined the scene to be shot. After the sliding operation, the ISO value is adjusted first, and then the user clicks the camera icon to take pictures according to the adjusted ISO value. , both ways are possible.

In step 102, when the smart terminal detects the ISO adjustment trigger operation information, the ISO value of the camera is increased from the current first value to the second value, such as from 100 (first value) to 400 (second value). ; It is equivalent to modifying the value of the parameter ISO based on which the camera takes photos, and the subsequent cameras will take photos according to the second value. As the value of ISO is increased, the shutter speed of the camera will be accelerated, which will significantly improve the clarity of photos in moving scenes compared to before the adjustment.

It should be noted that the ISO adjustment trigger operation information is actively executed by the user of the smart terminal, because only the user knows the photo in which scene he is currently taking. For example, if the user takes a static photo (such as a sculpture or an environmental scene), then there is no need to perform ISO adjustment trigger operation information, such as no need to swipe on the screen, and the smart terminal will use the default ISO automatic adjustment Mode, you can take a photo with a relatively low ISO value; if the user is shooting a moving scene, for example, the user wants to shoot a running animal, then the user knows that what he wants to shoot is a very fast object, then Execute ISO adjustment trigger operation information, such as clicking the camera icon and then sliding on the screen, thereby triggering the smart terminal to increase the ISO value and speed up the shutter speed, and the photos of running animals taken at this time will be clear.

It can be seen that the camera parameter adjustment device of the control layer of the smart phone can first judge whether the ISO adjustment trigger operation information is detected after detecting that the camera mode is activated. Then increase the ISO value; if no screen sliding is detected, just take a picture normally, that is, take a picture according to the usual default automatic mode.

Further, when the smart terminal increases the ISO value, there may be multiple specific ways of how to increase the ISO value. Two optional ISO adjustment methods are listed below:

For example, when the camera of a smart terminal takes a photo, it needs to use the ISO parameter, and the preset value range of the ISO has been stored in the smart terminal, such as from 100 to 1000, and usually the default value of the smart terminal is ISO Automatic adjustment mode, such as automatically selecting the ISO value to be used according to the intensity of the external light. Then in this embodiment, after the smart terminal detects the ISO adjustment trigger operation information, it will increase the ISO value, and can automatically increase the ISO value to the maximum value in the above preset value range, and automatically use the maximum ISO value to take pictures .

For another example, the smart terminal may not use the maximum value of the ISO preset range, but a value in the middle of the preset range; and, it may be set to, according to the size of the sliding speed when the user slides on the screen, to adjust the ISO value. For example, when the smart terminal detects a sliding operation on the screen, it also obtains the sliding speed of the sliding operation at the same time, so that the camera parameter adjustment device at the control layer adjusts the ISO according to the sliding speed. binary value) is higher. Optionally, a method that can also be adopted is to establish a preset corresponding relationship between the sliding speed and the ISO value, and determine the adopted ISO value according to the corresponding relationship and the detected sliding speed value.

The above method of adjusting the ISO according to the sliding speed of the sliding operation can be applied to the situation where the preset value range of the ISO in the smart terminal is relatively large, and of course other situations can also be applied. The advantage of this method is that the user can choose the corresponding ISO parameter value according to the scene he wants to shoot. For example, if the user wants to shoot a moving car, but the speed of the car is relatively slow, the user will The sliding speed can be slightly slower when sliding, because the ISO value can be shot clearly without increasing too much; if the user wants to shoot a fast-running animal, the speed is very fast, then the user can slide quickly when sliding, so that The smart terminal increases the ISO value to a very high value and greatly increases the shutter speed to capture clear photos.

Furthermore, in the method of the embodiment of the present invention, after the smart terminal detects that the photographing mode of this photo shooting ends, it still adjusts the ISO value to the first value, and returns to the automatic adjustment mode. That is to say, the behavior of increasing the ISO according to this method is temporary, and it can only be effective for this photo shoot. After the photo is taken this time, the ISO setting can be restored to the usual automatic mode, so that the user can shoot as he likes The photos in the mobile scene can not affect the default settings in the common state.

In order to realize the above photographing parameter adjustment method, an embodiment of the present invention also provides a photographing parameter adjustment device, the structure of which is shown in Figure 5, including: a detection module 41 and an adjustment module 42; wherein,

The detection module 41 is configured to detect that the photographing mode is started, and receive sensitivity ISO adjustment trigger operation information in the photograph mode; wherein, the function of the sensitivity ISO adjustment trigger operation information is to indicate to increase the value of ISO, so that The target object in the moving scene can be captured clearly, because the shutter speed is also accelerated when the ISO value is increased, and the clearer the moving object is.

The adjustment module 42 is configured to increase the ISO value of the camera from the current first value to a second value, so that the camera can take pictures according to the second value. For example, the first value is 100 and the second value is 400.

Further, the sensitivity ISO adjustment trigger operation information detected by the detection module 41 includes: sliding operation information on the screen. For example, the sliding operation information may be sliding on the camera preview area of the smart phone, or it may be when the user clicks and holds the camera icon of the smart phone (in a mobile phone with a touch screen, selecting this icon means that the user indicates to start taking the current picture) , you can keep pressing the icon and then slide it to trigger the adjustment of the ISO value, and you can shoot quickly in one go.

For example, the sliding operation information on the screen includes: a sliding speed of the sliding operation. The adjustment module 42, when adjusting the ISO value, the faster the sliding speed, the higher the second value.

Further, the second value is the maximum value in the preset value range. For example, if the preset value range in a smartphone is 100-1000, you can directly adjust the current ISO value to the maximum value of 1000.

Further, the adjustment module 42 is also configured to adjust the ISO value to the first value and return to the automatic adjustment mode after the detection module detects that the photographing mode of this photo shooting ends.
