Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating an image acquisition method according to an exemplary embodiment, which is applied to a mobile terminal. Referring to fig. 1, the method comprises the steps of:
s11: displaying a first image acquired in a first mode;
s12: obtaining and displaying a first image after zooming according to the zooming instruction;
s13: switching from a first mode to a second mode according to a photographing instruction;
s14: in a second mode, acquiring a second image;
s15: and cutting the second image according to the first image after zooming treatment to obtain a third image.
The zoom instructions may include: an zoom-in instruction and/or a zoom-out instruction.
When the mobile terminal collects images in the first mode, zooming processing can be conducted on the collected and displayed first images according to zooming instructions. Namely, when the mobile terminal performs image acquisition in the first mode, the mobile terminal supports zooming and framing.
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 the zooming process cannot be obtained and displayed according to the zooming instruction. I.e. the mobile terminal does not support zoom framing when performing image acquisition in the second mode.
Taking zooming processing as an example, in the related art, when the mobile terminal adopts a mode of not supporting zooming and framing to collect an image, if the user needs to amplify the collected image, the user can only manually amplify the photographed image after photographing is completed, but can not amplify the displayed image in the framing process, which is not beneficial to the convenience of the user in image collection.
It is noted that when the user selects to perform image acquisition in the second mode, a second image acquired by the second mode acquisition may be displayed. When the user selects to collect the image in the second mode, the image collecting device can switch from the second mode to the first mode according to the zooming command, collect and obtain the first image, and obtain and display the first image after zooming.
In the image acquisition process of switching from the first mode to the second mode, the display screen of the mobile terminal can maintain to display the first image after zooming until the third image is acquired, and switch to display the third image, or maintain until the third image is acquired. It should be noted that the third image may not be displayed during the image acquisition. In S15, by comparing the content displayed in the first image after the zooming process with the content displayed in the second image, the content displayed in the first image after the zooming included in the second image is recognized, and the area including the content displayed in the first image after the zooming is 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 zoomed second image and the content displayed by the zoomed first image may be compared, and the area having the same content as the first image displayed by the zoomed second image may be identified as the third image.
In some embodiments, S15 comprises: and cutting out the image content contained in the first image after the zooming treatment 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 expected to be shot by a user 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 processing 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, the image stored in the mobile terminal after the mobile terminal photographs according to the photographing instruction is the third image. When the user views the image obtained by this photographing, the mobile terminal displays a third image as well.
Taking a mobile terminal as an example of a mobile phone, after the mobile phone collects images by applying the method provided by the embodiment of the disclosure, the images stored in the mobile phone album are third images.
Because the live-zoom framing cannot be performed in the second mode, the user requirement is difficult to meet, and the first mode supports the zoom framing, the first image after the zoom processing can be obtained and displayed according to the zoom instruction, so that the requirement of the user on the live-zoom framing function in the image acquisition process is 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 is acquired and displayed according to the zooming instruction, so that the mobile terminal can automatically select the mode supporting zooming to perform real-time zooming framing when the image acquisition is performed, manual selection of a user is not needed, and the user experience is improved.
And the second image is acquired in the second mode according to the second mode, and the second image is cut according to the first image after zooming processing, so that the mobile terminal can automatically cut the second image according to the first image after zooming processing under the condition that a user does not feel the second image, and the third image is obtained.
In some embodiments, the resolution of the first image is less than the resolution of the second image;
and/or the number of the groups of groups,
the resolution of the first image is smaller 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 ten thousand pixels, 6400 ten thousand 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 that is displayed after the image has been enlarged.
The second mode may include a high definition photographing mode. The resolution of the image acquired in the high-definition photographing mode is greater than or equal to 4800 ten thousand pixels. However, when the mobile terminal performs photographing in the high-definition photographing mode, zoom framing is not supported.
When a mobile terminal adopts a high-definition photographing mode to photograph a building far away from the mobile terminal, a user needs to zoom and view a view, and usually, a small-size word or structure on the building cannot be clearly seen when the user views the view. However, since the high-definition photographing mode does not support zooming and framing, in the related art, a user can only photograph the building in the high-definition photographing mode to obtain a photograph, and then enlarge and cut the obtained photograph, so that a small-sized word or structure on the building can be clearly seen from the cut photograph, and the displayed picture cannot be zoomed 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 higher resolution than the first image is acquired and obtained in the second mode, the second image is cut to obtain the third image, and the resolution of the third image is improved, so that a user can zoom and view in the first mode and obtain an image with better definition according to the photographing instruction when the user performs image acquisition, the problem that the high-definition photographing mode cannot perform zoom and view in the prior art is solved, and user experience is improved.
In addition, when the resolution of the third image is larger than that of the first image, the resolution of the third image is also larger 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 zooming 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 where the area of the display area of the mobile terminal is unchanged, the sharpness of the first image before the zoom processing displayed by the mobile terminal is higher than the sharpness of the first image after the zoom processing displayed.
The resolution of the first image after the zoom processing is smaller than the preset resolution, and the image quality of the first image after the zoom processing can be considered to be poor. If the first image after zooming is taken as a photo generated by shooting according to a shooting instruction, the photo is difficult to meet the requirement of a user. 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 zooming is smaller than the preset resolution, the mobile terminal is switched from the first mode to the second mode according to the photographing instruction, so that the image obtained by photographing according to the photographing instruction is ensured to be 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. When the mobile terminal enters the first mode, the mobile terminal displays the acquired image in the first mode again.
When the mobile terminal displays the acquired image in the first mode, the mobile terminal can be considered to successfully complete the 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 the second mode and enter the first mode, so that the mobile terminal can enter the next photographing operation, and under the first mode, the user can be allowed to continue zooming and framing in the next photographing operation, so that the mobile terminal can perform zooming and framing every time when photographing continuously for many times, and the user experience is improved.
In some embodiments, the method further comprises: and displaying the multimedia information when switching between the first mode and the second mode.
The multimedia information may include: preset still pictures or preset animations, etc. The preset still picture may include: scenic pictures or animal pictures, etc. The preset animation may include: a rotating circle or flashing text (e.g., "please wait").
By way of example, the mobile terminal may include an image acquisition component having the first mode and the second mode. The image acquisition assembly is switchable between a first mode and a second mode by moving an included lens or the like.
It will be appreciated that when the mobile terminal includes an image acquisition assembly and the image acquisition assembly is switched between the first mode and the second mode, it may take some time inside the image acquisition assembly to complete the switching. The user needs to wait for the switching to be completed before continuing to acquire the image. Thus, the time for completing the handoff may reduce the user experience.
In the embodiment of the disclosure, by displaying the multimedia information when switching between the first mode and the second mode, the reduction of user experience caused by the delay of switching between the first mode and the second mode can be reduced, and the better user experience is ensured.
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 adopt the high-definition mode to take pictures, and the picture quality of the pictures taken by the lens in the high-definition mode is higher and higher, and can reach 6400 ten thousand pixels, even 1 hundred million pixels. The photograph taken in the high definition mode is still very clear, even if magnified many times.
However, when taking a picture in the high-definition mode, the lens cannot perform zooming, and only a picture can be taken in the fixed-focus mode. If the lens photographed in the high-definition mode needs to be zoomed, the photograph photographed in the high-definition mode can be enlarged and cut only after the lens is photographed in the high-definition mode. When the camera lens taking the pictures in the high-definition mode takes the pictures, the obtained pictures can be cut only after the shooting is finished so as to achieve the amplifying effect, and zooming and framing can not be carried out when a user views the pictures, so that the user experience is not improved.
In some embodiments, the mobile terminal may include a first image acquisition component and a second image acquisition component, in a first mode, acquiring a first image by the first image acquisition component; in the second mode, a second image is acquired by a second image acquisition assembly. The resolution of the image acquired by the first image acquisition component is smaller than that of the image acquired by the second image acquisition component.
The first image acquisition component supports zoom framing. Namely, the first image acquisition component can obtain a first image after zooming according to the zooming instruction. The first image acquisition assembly may include: a tele lens. The focal length of the tele lens may be greater than 50 millimeters.
The resolving power of the second image acquisition component is higher than that of the first image acquisition component. The second image acquisition assembly may include: and (5) fixing the focus lens. It can be understood that the fixed focus lens is a lens with a fixed focal length.
The mobile terminal can switch between the first mode and the second mode by adopting different image acquisition components, so that the real-time zooming view finding can be carried out in the image acquisition process, the image obtained after the image acquisition is finished can be ensured to have higher image quality, and the requirement of a user on higher image quality is met. And 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, so that the compatibility with the related technology is strong and the hardware cost of the mobile terminal is low.
