Referring to fig. 2, the present application provides a first embodiment of an image acquisition method, where the image acquisition method is applied to a terminal device with a camera, the terminal device includes at least two cameras, and focal segments captured by the cameras are different, and the image acquisition method includes:
step S10, when detecting the trigger operation of the camera, opening each camera, controlling each camera to pick up image information respectively, and forming a camera preview interface;
the terminal device in this embodiment may be a mobile phone, a tablet, a camera, or the like. The terminal equipment is provided with a camera application, and a user can trigger the camera application to carry out shooting work.
When a user triggers a camera application of the terminal equipment, the terminal equipment starts each camera and controls each camera to pick up image information respectively. The acquired image information is different because the focal sections shot by the cameras are different, and the cameras respectively transmit the acquired image information to different processing modules, and the image information is stored in different storage areas after being processed by the processing modules. And the same trigger operation is correspondingly associated with the acquired image data.
It should be noted that the terminal device in this embodiment includes, but is not limited to, a tele camera, a wide camera, and an ultra-wide camera, where a focal length shot by the tele camera is 3X to 30X, a focal length shot by the wide camera is 1X to 3X, and a focal length shot by the ultra-wide camera is 0.6X to 1X.
The terminal equipment is provided with a display interface, and after the camera application is triggered, image data collected by the cameras are displayed on the display interface in a preview mode.
It can be understood that, based on the embodiment that at least two cameras simultaneously pick up image information, and the picked-up image information is obtained based on different focal lengths and different coordinates, the camera preview interface may be formed based on a combination of multiple sets of the image information.
Specifically, in an embodiment, referring to fig. 3, the camera preview interface is formed in a manner including, but not limited to, one of the following:
step S11, determining a target camera according to a preset zoom value;
step S12, combining main preview image information and supplemental preview image information to form the camera preview interface, where the main preview image information is image information picked up by the target camera, and the supplemental preview image information is image information picked up by other cameras except the target camera.
Namely, the main preview image information is determined according to the preset zoom value, and then the main preview image information is corrected by using the image information of other cameras, so that the display effect of the shot image is improved.
Specifically, the preset zoom value may be a default zoom value of the terminal device, or the preset zoom value may be a set zoom value of a user. And if the user triggers the camera application, the terminal equipment controls each camera to be started, and each camera respectively picks up image information and transmits the image information back to each processing module. At this time, if the terminal device does not detect the user-set zoom value, the default zoom value of the terminal device is adopted as the preset zoom value. And if the terminal equipment detects that the user sets the zoom value of the current camera, the set zoom value of the user is adopted as the preset zoom value. It can be understood that, a zoom control is arranged on the terminal device, and a user can set a zoom value by triggering the zoom control.
When a camera application of the terminal device is triggered, the default of the camera preview interface is a default zoom value set by the system, and when it is detected that a user triggers a zoom control to adjust the zoom value of the preview interface, the default zoom value is adjusted to be the set zoom value. In the focusing process, since the present embodiment employs a plurality of cameras to pick up image information simultaneously, when the implied zoom value is adjusted to the set zoom value, the terminal device directly takes the image information picked up by the camera corresponding to the set zoom value as the main preview image information and the image information picked up by the other cameras as the supplementary preview image information, and combines and images without the need of the exemplary technique: when the default zoom value is adjusted to the set zoom value, the camera corresponding to the default zoom value is closed, the camera corresponding to the set zoom value is opened, and then image information is picked up. The embodiment omits the pick-up time of the image information after the zoom value is adjusted in the image pick-up process, and can avoid missed moment pictures caused by adjusting the zoom value to a certain extent.
It should be noted that, in this embodiment, a target camera is determined according to the preset zoom value, where the target camera is a camera corresponding to the preset zoom value, and if the preset zoom value is 1.0X, the corresponding target camera is a wide-angle camera; if the preset zoom value is 0.6X, the corresponding target camera is an ultra-wide-angle camera.
In this embodiment, after a target camera is determined according to a preset zoom value, image information picked up by the target camera is used as main preview image information, image information picked up by other cameras except the target camera is used as supplementary preview image information, and then the main preview image information is corrected by using the supplementary preview image information, so as to finally form a preview interface.
Because the picture is all by the object through the equal proportion formation of image and present on the photosensitive element of camera, and each photosensitive element all comprises different plane pixel, because the position coordinate of each camera has relative position, a plurality of cameras shoot same when the object of shooing, there are the visual angle of a plurality of differences, if merge into a picture with the data at a plurality of different visual angles, the little stereoeffect of the object of shooing is stronger, also can be stronger on the reduction degree of visual angle impression, simultaneously because the difference of focus section formation of image, make at the composite picture, the fore-and-aft scene of picture also has the promotion by a wide margin in the definition.
Based on the camera preview interface in the embodiment, the image information picked up by the multiple cameras is combined to form the camera preview interface, and the multiple cameras form images, so that the camera preview interface in the embodiment has a good imaging effect.
Step S20, when the photographing triggering operation is detected, generating a picture according to the camera preview interface;
and step S30, saving the picture.
And the display interface of the terminal equipment is provided with a photographing determining control, when a user triggers the photographing determining control, the terminal equipment is judged to detect photographing triggering operation, and the terminal equipment generates a picture according to the image information currently displayed on the camera preview interface, stores the picture and finishes photographing.
In this embodiment, when the terminal device detects a camera trigger operation, the terminal device starts each camera, controls each camera to respectively pick up image information, generates a camera preview interface according to the image information picked up by each camera, and generates and stores a picture according to the camera preview interface when the terminal device detects a photographing trigger operation. Because the picture is formed by combining the image information of different focal segments acquired by a plurality of cameras simultaneously, the front and back scene definition of the picture and the stereo effect of the image in the picture are improved, and the imaging effect of the camera is good.
Further, referring to fig. 4, the present application provides a second embodiment of an image obtaining method, and based on the first embodiment, the step of combining the main preview image information and the supplemental preview image information to form the camera preview interface includes:
step S121, acquiring an area overlapping with the main preview image information in the supplemental preview image information;
step S122, merging the region overlapping with the main preview image information in the supplemental preview image information into the main preview image information, and forming the camera preview interface.
At least two cameras pick up the image information of the same object from different angles, so that an overlapping area and a non-overlapping area are necessary between each image information, the depth information of the edge position of the formed picture is increased through the combination of the overlapping areas in the embodiment, and the transparency of the picture content can be improved qualitatively. And based on multi-focus segment fusion, the edge of the picture can be supplemented and corrected through the supplementary preview image information of other focus segments, and compared with a single shot picture, the edge of the shot picture cannot be distorted.
In this embodiment, the supplementary preview data is converted to the plane where the main preview data is located by coordinate conversion, so that the supplementary preview data is calibrated on one plane, and thus, under the condition that a pixel point is not changed, four-axis scattering extension may exist by taking the point as a center.
The coordinate conversion mode is that the coordinate of the main preview image data is used as a central coordinate, and the supplementary preview information is converted to the central coordinate based on the relative relation between the central coordinate and the coordinate of the supplementary preview image information, so as to complete the coordinate conversion.
Specifically, the step of combining the region overlapping with the main preview image information in the supplemental preview image information into the main preview image information to form the camera preview interface includes:
acquiring coordinates of the target camera and relative position parameters of the other cameras and the target camera;
calculating the coordinate position of the pixel of the region overlapped with the main preview image information in each supplementary preview image information according to the coordinate of the target camera and the relative position parameter;
and converting each pixel into a pixel plane corresponding to the main preview image information according to the coordinate position to form the camera preview interface.
It should be noted that the target camera is located as the central coordinate, and the phase position parameter refers to a relative position of the coordinate positions of the other cameras with respect to the coordinate of the target camera. After the coordinates of the target camera and the relative position parameters are acquired, calculating the coordinate position of the pixel of the area, which is overlapped with the main preview image information, of the supplementary preview image information at the coordinates of the target camera, and specifically converting the coordinates of the pixel at the corresponding camera to the coordinates of the target camera based on the relative position parameters, so that each pixel point is converted to the pixel plane of the main preview image information to complete the combination with the main preview image information, and further displaying the combined image in the camera preview interface.
In the embodiment of the invention, the edge depth information of a single photo is increased through multi-path fusion imaging, so that the transparency of the photo content can be qualitatively improved; the problem of poor edge resolution is optimized, so that edge noise of the picture is generated, the picture is indirectly changed into a large pixel through multi-pixel splicing and proofreading, and the light sensitivity and the color restoration degree of the camera are improved.
If the user needs to adjust the zoom value first in the shooting process of the terminal device and then takes a picture, the process of adjusting the zoom value needs time, and the user may miss an instant picture due to adjustment of the zoom value.
Specifically, as a third embodiment of the image obtaining method provided by the present application, referring to fig. 5 based on the first and/or second embodiment, the image obtaining method performs the step of saving the picture and also performs:
step S40, saving the image information picked up by each camera and associating the picture with each image information.
That is, after the user triggers the photographing operation, the terminal device generates a picture according to the camera preview interface, stores the picture, stores the image information picked up by each camera, and associates the picture with the image information picked up by each camera. Therefore, the pictures are correspondingly associated with the multi-path image information data, when the terminal equipment carries out zooming processing on the pictures, the multi-path image information can be called based on the association relation between the pictures and the image information data, and the data processing is carried out by adopting the originally picked image information, so that when the zooming processing is carried out on the pictures, the definition of the pictures can be always kept as same as that of the original pictures.
Based on the picture associated with the image information picked up by each camera, when the user edits the image, the image obtaining method of the embodiment of the application may perform the following processing on the picture:
referring to fig. 5 specifically, after the step of saving the image information picked up by each camera and associating the picture with each image information, the method further includes:
step S50, when the picture editing operation is detected, acquiring editing parameters corresponding to the editing operation;
step S60 of acquiring target image information corresponding to the editing parameter from each piece of image information associated with the picture;
and step S70, generating edited target picture preview data according to the target image information.
The method comprises the steps that a user can click the picture to edit the picture, when the terminal device detects that the user carries out editing operation triggered based on the picture, editing parameters corresponding to the editing operation are obtained, then target image information corresponding to the editing parameters is obtained from each piece of image information related to the picture, and edited target picture preview data are generated by adopting the target image information.
Wherein the editing operation comprises at least one of zooming in, zooming out and cropping, and the editing parameters comprise one or more of zooming in multiple, zooming out multiple and cropping size. When a user magnifies and edits a picture, target image information corresponding to the magnification factor is searched from each image information associated with the picture, and then the target image information is used as target picture preview data for the user to preview the display effect of the magnified picture. When the user triggers the zoom-out operation or the clipping operation, the terminal device processes the picture in the same manner as described above, which is not described herein again.
It is understood that, in this embodiment, the focal length of each camera is different, and the picked-up image information is also divided according to the zoom value, so as to facilitate reasonable invoking of the image information associated with the picture to generate the target image preview data, so that the edited picture display effect is optimal, in an embodiment, referring to fig. 6, the step of obtaining the target image information corresponding to the editing parameter from each image information associated with the picture includes:
step S61, determining the zoom value of the adjusted picture according to the editing parameters;
step S62, acquiring a focal length corresponding to the zoom value, and taking a camera matched with the focal length as a target camera;
step S63, regarding the image information picked up by the target camera as the target image information.
That is, in this embodiment, when the editing parameter corresponding to the editing operation is obtained, the editing parameter is converted into a zoom value, then a camera matched with a focal length where the zoom value is located is determined according to the zoom value, image information picked up by the camera is adopted as target image information, and then the target picture preview data is generated according to the target image information.
The image information picked up by each camera is different based on different focal sections of the cameras, the terminal equipment determines a target camera according to the zoom value of the picture adjusted by the editing parameters, the target image information corresponding to the target camera is adopted to generate target picture preview data, and the target image information is original information collected by the cameras and is the same as the image information of the focal section of the zoom value adjusted by the picture, and pixels of the target image information do not need to be changed, so that the image displayed by the adjusted target picture preview data is clear, and the problem that the definition can be reduced in a mode of achieving the purpose of focusing by changing the image pixels in the exemplary technology is solved. In contrast, the embodiment improves the clear effect of editing the picture.
In addition, in the embodiment, the image information which is most matched with the editing parameter is determined through the zoom value, and then the target picture preview data is generated by adopting the image information, so that the display effect of the convenient picture is optimized.
It should be noted that each focal length has an upper limit value and a lower limit value, the upper limit value or the lower limit value of two adjacent focal lengths is the same, and if the zoom value is between the upper limit value or the lower limit value, but does not belong to the upper limit value or the lower limit value, the target picture preview data is generated in the following two ways:
firstly, generating edited target picture preview data based on the target image information;
that is, the edited target picture preview data is generated by directly adopting the target image information, so that the adjusted target picture preview data meets the focal length.
Secondly, the target image information is adjusted according to the zoom value, and edited target picture preview data is generated based on the adjusted target image information.
