Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating an image capturing method applied to a mobile terminal according to an exemplary embodiment. Referring to fig. 1, the method includes the steps of:
s11: displaying a first image acquired in a first mode;
s12: obtaining and displaying a first image after zooming processing according to the zooming instruction;
s13: switching from the first mode to the second mode according to the photographing instruction;
s14: acquiring and obtaining a second image in a second mode;
s15: and cutting the second image according to the first image after the zooming processing to obtain a third image.
The zoom instructions may include: a zoom-in instruction and/or a zoom-out instruction.
When the mobile terminal collects images in the first mode, zooming processing can be carried out on the collected and displayed first images according to the zooming instruction. Namely, the mobile terminal supports zooming and framing when the mobile terminal acquires images in the first mode.
And the mobile terminal performs fixed-focus shooting in the second mode. It should be noted that, when the mobile terminal performs image acquisition in the second mode, the second image after zoom processing cannot be obtained and displayed according to the zoom instruction. Namely, when the mobile terminal performs image acquisition in the second mode, zooming and framing are not supported.
Taking zoom processing as an example of magnification processing, in the related art, when the mobile terminal acquires an image in a mode that does not support zoom framing, if a user needs to magnify the acquired image, the user can only manually magnify the photographed image after photographing is completed, but cannot magnify the displayed image in the framing process, which is not favorable for the convenience of image acquisition of the user.
It is noted that when the user selects the image acquisition in the second mode, a second image acquired by the second mode acquisition may be displayed. And when the user selects to collect the image in the second mode, the second mode can be switched to the first mode according to the zoom instruction, the first image is collected and obtained, and the first image after the zoom processing is obtained and displayed.
In the image acquisition process of switching from the first mode to the second mode, the display screen of the mobile terminal may maintain to display the first image after the zoom processing until the third image is acquired, and switch to display the third image, or maintain to obtain the third image. It is noted that the third image may not be displayed during the image acquisition. In S15, the content of the zoomed first image display included in the second image may be recognized by comparing the content of the zoomed first image display with the content of the second image display, and the region including the content of the zoomed first image display may be cut out in the second image as the third image.
Alternatively, the zoom instruction may include a zoom magnification. In S15, the second image may be zoomed according to the zoom magnification, and then the content displayed by the zoom-processed second image and the content displayed by the zoom-processed first image may be compared, and a region in the zoom-processed second image where the content displayed by the zoom-processed first image is the same may be identified as the third image.
In some embodiments, S15 includes: and cutting out the image content contained in the first image after the zooming processing from the second image to obtain a third image.
The content displayed by the third image can be completely consistent with the content displayed by the first image after zooming, so that the third image obtained by the mobile terminal is the displayed first image after zooming, and the image content consistent with the image content which the user wants to shoot can be obtained by the image acquisition method, so that 'what you see is what you get' is realized.
It is understood that the first image after the zoom process is the image content that the user wishes to capture. The third image is an image finally obtained by the mobile terminal according to the photographing instruction, that is, after the mobile terminal performs photographing according to the photographing instruction, the image stored in the mobile terminal is the third image. When the user views the image obtained by the photographing, the mobile terminal displays a third image.
Taking the mobile terminal as a mobile phone as an example, after the mobile phone collects images by applying the method provided by the embodiment of the disclosure, the image stored in the mobile phone album is a third image.
Because the second mode can not carry out the real-time zooming view finding, the user requirement is difficult to meet, and the first mode supports the zooming view finding, the first image after the zooming processing can be obtained and displayed according to the zooming instruction, so that the requirement of the user on the real-time zooming view finding function in the image acquisition process can be met.
According to the scheme provided by the embodiment of the disclosure, the first image acquired in the first mode is displayed, and the first image after zooming processing is acquired and displayed according to the zooming instruction, so that the mobile terminal can automatically select the mode supporting zooming to zoom and view in real time when image acquisition is carried out, manual selection of a user is not needed, and the improvement of user experience is facilitated.
Moreover, the first mode is automatically switched to the second mode according to the photographing instruction, the second image is collected in the second mode, the second image is cut to obtain the third image according to the first image after zooming, and the mobile terminal can automatically cut the second image according to the first image after zooming under the condition that a user does not sense the third image.
In some embodiments, the resolution of the first image is less than the resolution of the second image;
and/or the presence of a gas in the gas,
the resolution of the first image is less than the resolution of the third image.
Illustratively, the resolution of the first image may be less than or equal to 1200 ten thousand pixels.
The resolution of the second image may include: 4800 million pixels, 6400 million pixels, or 1 hundred million pixels, etc.
It will be appreciated that the more pixels an image comprises, the higher the sharpness of the image and the higher the sharpness of the image displayed after the image has been enlarged.
The second mode may include a high-definition photographing mode. The resolution of the image collected in the high-definition photographing mode is larger than or equal to 4800 ten thousand pixels. However, when the mobile terminal performs shooting in the high-definition shooting mode, zoom framing is not supported.
When the mobile terminal is used for shooting a building far away from the mobile terminal in a high-definition shooting mode, characters or structures with small sizes on the building cannot be seen clearly during framing, and a user needs to perform zooming and framing. However, since the high-definition photographing mode does not support zoom framing, in the related art, a user can only photograph the building in the high-definition photographing mode to obtain a photo, and then enlarge and crop the obtained photo, so that a word or a structure with a smaller size on the building can be seen clearly from the cropped photo, and the displayed picture cannot be subjected to zoom processing during framing, which is difficult to meet the photographing requirement of the user.
According to the embodiment of the disclosure, the first mode is switched to the second mode according to the photographing instruction, the second image with the resolution higher than that of the first image is acquired in the second mode, the second image is cut to obtain the third image, and the improvement of the resolution of the third image is facilitated, so that a user can zoom and view in the first mode when acquiring the images, and can acquire the images with better definition according to the photographing instruction, thereby solving the problem that the high-definition photographing mode in the prior art cannot zoom and view, and improving the user experience.
In addition, when the resolution of the third image is greater than that of the first image, the resolution of the third image is also greater than that of the first image after zooming, so that the image obtained according to the photographing instruction can be ensured to have better definition, and the requirement of a user for obtaining a high-definition photo is met.
In some embodiments, the method further comprises: acquiring the resolution of the first image after zooming;
s13 may include: and when the resolution of the first image after the zooming processing is smaller than the preset resolution, switching from the first mode to the second mode according to the photographing instruction.
It can be understood that, in the case that the display area of the mobile terminal is not changed, the definition of the first image before the zoom process displayed by the mobile terminal is higher than that of the first image after the zoom process.
When the resolution of the first image after the zoom processing is smaller than the preset resolution, the image quality of the first image after the zoom processing may be considered to be poor. If the first image after the zooming processing is taken as the photo generated by shooting according to the shooting instruction, the photo is difficult to meet the user requirement. The preset resolution may include: 800 ten thousand pixels or 1200 ten thousand pixels, etc.
In the embodiment of the disclosure, when the resolution of the first image after the zooming processing is smaller than the preset resolution, the first mode is switched to the second mode according to the photographing instruction, so that it can be ensured that the image obtained by photographing by the mobile terminal according to the photographing instruction is a third image with higher resolution, and further, better user experience is ensured.
In some embodiments, the method further comprises: after the third image is obtained, the second mode is exited and the first mode is entered.
After the third image is obtained, the current photographing operation can be considered to be completed.
It is noted that the mobile terminal may display multimedia information during the exit from the second mode and entry into the first mode. And after the mobile terminal enters the first mode, the mobile terminal displays the image acquired in the first mode again.
When the mobile terminal displays the image acquired in the first mode, it may be considered that the mobile terminal has successfully completed switching from the second mode to the first mode. And when the mobile terminal is in the first mode, allowing the mobile terminal to zoom the displayed image according to the zoom instruction.
After the third image is obtained, the mobile terminal can automatically exit from the second mode and enter the first mode, so that the mobile terminal can enter the next photographing operation, and the user can be allowed to continue zooming and framing in the next photographing operation by entering the first mode, so that the mobile terminal can zoom and frame every time when continuously photographing for multiple times, and the user experience is improved.
In some embodiments, the method further comprises: when switching between the first mode and the second mode, the multimedia information is displayed.
The multimedia information may include: presetting a static picture or presetting animation and the like. The presetting of the still picture may include: landscape pictures or animal pictures, etc. The preset animation may include: a rotating circle or flashing text (e.g., "please wait a little more").
Illustratively, the mobile terminal may comprise an image capturing component having the first mode and the second mode. The image acquisition assembly may be switched between the first mode and the second mode by moving an included lens or the like.
It will be appreciated that when the mobile terminal includes an image capture assembly and the image capture assembly is switched between the first mode and the second mode, a certain amount of time may be required within the image capture assembly to complete the switch. The user needs to wait for the switching to be completed before continuing to acquire the image. Thus, the time for completing the handover may degrade the user experience.
In the embodiment of the disclosure, when the first mode and the second mode are switched, the multimedia information is displayed, so that the reduction of user experience caused by the switching delay between the first mode and the second mode can be reduced, and the user experience is ensured to be better.
In the related art, an electronic device capable of image acquisition may generally include a plurality of image acquisition components. Taking a mobile phone as an example, the mobile phone may include a plurality of lenses. The lens supporting the high-definition mode can be used for taking pictures in the high-definition mode, and the picture quality of pictures taken by the lens in the high-definition mode is higher and higher, and can reach 6400 ten thousand pixels or even 1 hundred million pixels. The photographs taken in high definition mode, even magnified many times, are still very clear.
However, when taking a picture in the high-definition mode, the lens cannot be zoomed, and only a picture can be taken in the fixed-focus mode. If the lens shot in the high-definition mode needs to be zoomed, the picture shot in the high-definition mode can be enlarged and cut only after the lens shot in the high-definition mode is shot. When the camera lens of shooing with high definition mode was shot promptly, can only cut out the photo that obtains after accomplishing to the shooting in order to realize the enlarged effect, and can not zoom when the user finds a view and find a view, be unfavorable for improving user experience.
In some embodiments, the mobile terminal may include a first image acquisition component and a second image acquisition component, and in the first mode, a first image is acquired through the first image acquisition component; in the second mode, a second image is acquired by the second image acquisition assembly. The resolution of the image collected by the first image collection assembly is smaller than the resolution of the image collected by the second image collection assembly.
The first image capturing assembly supports zoom framing. Namely, the first image acquisition assembly can obtain a first image after zooming processing according to the zooming instruction. The first image acquisition assembly may include: a telephoto lens. The focal length of the telephoto lens may be greater than 50 mm.
The analytic force of the second image acquisition assembly is higher than that of the first image acquisition assembly. The second image acquisition assembly may include: fixed focus lens. It is understood that a fixed focus lens is a lens with a fixed focal length.
The mobile terminal can be switched between the first mode and the second mode by adopting different image acquisition assemblies, so that the real-time zooming and framing can be performed in the image acquisition process, the image acquired after the image acquisition is finished can be ensured to have higher image quality, and the requirement of a user on the higher image quality is met. Moreover, the image acquisition assembly capable of supporting zooming and framing and the image acquisition assembly capable of performing high-definition photographing in the related technology can be continuously used, the compatibility with the related technology is strong, and the hardware cost of the mobile terminal is low.
