Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

In one embodiment, as shown in FIG. 1 , an image display method is provided. This embodiment uses the application of this method to electronic equipment for illustration. Electronic equipment can be, but not limited to, various personal computers, notebook computers, smart Mobile phones, tablets and portable wearables. In this embodiment, the method includes the following steps:

Step 102, under the condition that the zoom ratio of the control image enters the preset ratio interval, the original image taken by the original camera and the relay image taken by the relay camera are acquired; the preset ratio interval includes the corresponding zoom ratio of the original camera and the relay camera corresponding magnification.

The zoom ratio (zoom) refers to the zoom ratio of the image in the display interface. When the zoom ratio increases, it means that the image is enlarged, and the field of view (FOV) of the image in the display interface becomes smaller, and the focal length of the camera increases; when the zoom ratio decreases, it means that the image is zoomed out, and the field of view of the image in the display interface is displayed. Larger, the focal length of the camera decreases. For example, if the image content XX in the display interface is enlarged, that is, the zoom ratio of the image is increased, the field of view of the image in the display interface becomes smaller, and the scale of the image content XX displayed in the display interface also becomes larger. The display interface is an interface for display on the screen of the electronic device.

The electronic device includes at least two cameras, and the at least two cameras include an original camera and a relay camera. Both the original camera and the relay camera are set up on the same side of the electronic device and capture the same scene. The original camera is the camera that captures images before the zoom ratio enters the preset ratio range and is used for display in the display interface. The relay camera is a camera that takes images for display in the display interface after the zoom ratio passes the preset ratio range. That is to say, before the zoom ratio enters the preset ratio range, the display interface displays images captured by the original camera, and after the zoom ratio passes the preset ratio range, the display interface displays images captured by the relay camera. The target image displayed with the magnification within the preset magnification range is the transition image between the image captured by the original camera and the image captured by the relay camera.

The original image is the image captured by the original camera when the zoom ratio enters the preset ratio range. The relay image is the image captured by the relay camera when the zoom ratio enters the preset ratio range. The original image may be an image taken before the original camera is zoomed, or an image taken after the original camera is zoomed. Similarly, the relay image may be an image captured before the relay camera zooms, or an image captured after the relay camera zooms.

In the case that the magnification range of the original camera or the magnification range of the relay camera does not have the zoom magnification of the image, the image captured by the original camera or the image captured by the relay camera can be digitally zoomed to obtain the original image or relay image corresponding to the zoom magnification.

The preset magnification range is a preset magnification range for generating the target image. The preset magnification interval can be set as required, and the preset magnification interval includes the zoom ratio corresponding to the original camera and the zoom ratio corresponding to the relay camera.

Understandably, each camera has a corresponding zoom ratio. For example, the zoom ratio corresponding to the super wide-angle camera is 0.6X-1X, the zoom ratio corresponding to the wide-angle camera is 1X-5X, and the zoom ratio corresponding to the telephoto camera is 5X-60X, then the preset between the super wide-angle camera and the wide-angle camera The magnification range can be 0.8X-1.2X, and the preset magnification range between the wide-angle camera and the telephoto camera can be 4.8X-5.2X. For another example, if the zoom ratio corresponding to camera A is 0.6X-2X, and the zoom ratio corresponding to camera B is 1X-5X, then the preset ratio range may be 1X-2X. Among them, 0.6X means that the ratio of the size of the actual subject to the size in the image is 1:0.6, and 1X means that the ratio of the size of the actual subject to the size in the image is 1:1.

In one embodiment, the electronic device may determine the overlapping magnification range of the original magnification range and the relay magnification range according to the original magnification range of the original camera and the relay magnification range of the relay camera, and determine the preset magnification interval based on the overlapping magnification range.

The original magnification range is the magnification range corresponding to the focal length of the original camera. The relay magnification range is the magnification range corresponding to the focal length of the relay camera. The focal length refers to the range of the focal length of the camera.

Optionally, the electronic device may directly use the overlapping magnification range as the preset magnification interval, or may determine a preset magnification interval including the overlapping magnification range, or may determine a part of the overlapping magnification range as the preset magnification interval, and is not limited thereto. .

For example, the zoom ratio of the original camera is 0.6X-2X, and the corresponding zoom ratio of the relay camera is 1X-5X. Then, the overlapping magnification range between the original camera and the relay camera is 1X-2X, and the preset magnification range can be 1X-2X, 1.2X-1.8X, or 0.8X-2.2X.

In another embodiment, the electronic device sets a specific number of sampling points for a specific magnification interval, obtains the corresponding relationship between the sampling points and the magnification, and has the same scaling relationship between every two adjacent sampling points; obtains the specified magnification , and the specified number of sampling points corresponding to the specified magnification; based on the specified number of sampling points corresponding to the specified magnification, determine the upper limit and lower limit of the preset magnification interval from the correspondence between the sampling points and the magnification, and generate Preset magnification range.

The following formula can ensure the same scaling relationship between every two adjacent sampling points:

zoom _max = zoom _min *(x) ^N formula (1)

Among them, zoom _max is the upper limit value of a specific magnification interval, zoom _min is the lower limit value of a specific magnification interval, x is the zoom ratio between adjacent sampling points, and N is a specific number set for a specific magnification interval.

The corresponding relationship between sampling points and magnification is as follows:

Among them, n is the nth sampling point corresponding to zoom, zoom _max is the upper limit value of a specific magnification range, zoom _min is the lower limit value of a specific magnification range, x is the scaling ratio between adjacent sampling points, and N is set for a specific magnification range a specific amount. From this formula, it can be known that for a given zoom, it can be mapped to the corresponding sampling point.

For example, the specified magnification is 1X, and the specified number of sampling points corresponding to the specified magnification is M sampling points, then the upper limit of the preset magnification range is the magnification of the Mth sampling point that is greater than the specified magnification, and the preset magnification range The lower limit of is the magnification at which the Mth sampling point is smaller than the specified magnification.

The preset magnification range includes the zoom magnification corresponding to the original camera and the zoom magnification corresponding to the relay camera, and when the zoom magnification enters the preset magnification range, the original image of the original camera and the relay image of the relay camera can be obtained.

Fig. 2 is a schematic diagram of a preset magnification interval in an embodiment. The zoom ratio corresponding to the super wide-angle camera is 0.6X-1X, the zoom ratio corresponding to the wide-angle camera is 1X-5X, and the zoom ratio corresponding to the telephoto camera is 5X-60X, then the preset ratio range between the super wide-angle camera and the wide-angle camera It is 0.8X-1.2X, and the preset magnification range between the wide-angle camera and the telephoto camera is 4.8X-5.2X.

Step 104, in the time domain, the original time domain weight of each pixel point in the original image and the relay time domain weight of each pixel point in the relay image are obtained.

The original time domain weight is the weight factor of the pixels in the original image in the time dimension. The relay time domain weight is the weight factor of the pixels in the relay image in the time dimension.

In one embodiment, the electronic device obtains the original time domain weight of each pixel in the original image, and determines the relay time domain weight of each pixel in the relay image based on the original time domain weight; wherein, the original time domain weight and the relay time domain The sum of the weights is 1.

For example, the original time-domain weight of each pixel in the original image is A, and the relay time-domain weight of the pixel in the relay image is (1-A).

The electronic device obtains the original time-domain weight of each pixel in the original image, including: obtaining the current zoom ratio of the image, determining the difference between the current zoom ratio and the lower limit value of the preset ratio range, and dividing the difference by the preset ratio. Set the range value of the magnification interval to obtain the original time domain weight of each pixel in the original image.

The lower limit value of the preset magnification range is the minimum value in the preset magnification range, and the upper limit value of the preset magnification range is the maximum value in the preset magnification range. For example, if the preset magnification range is (zoom_min, zoom_max), the lower limit of the preset magnification range is zoom_min, and the upper limit of the preset magnification range is zoom_max. For another example, if the preset magnification range is 1X-5X, then the lower limit of the preset magnification range is 1X, and the upper limit of the preset magnification range is 5X.

The original time domain weight of each pixel in the original image can be calculated by the following formula:

Among them, α is the original time-domain weight of each pixel in the original image, zoom is the current zoom ratio, zoom _min is the lower limit value of the preset ratio range, and zoom _max is the upper limit value of the preset ratio range. Then the original time domain weight of each pixel in the relay image is (1-α).

In another embodiment, the electronic device obtains the relay time domain weight of each pixel in the relay image, and determines the original time domain weight of each pixel in the original image based on the relay time domain weight; wherein, the original time domain weight and the relay time The domain weights sum to 1.

In another embodiment, the electronic device acquires the original time-domain weight of each pixel in the input original image, and the relay time-domain weight of each pixel in the relay image.

It should be noted that in the time domain, the time coefficient or the zoom factor coefficient needs to be derived to ensure that the zoom factor will not change suddenly with time or zoom. For example, the original time-domain weight and the relay time-domain weight are related to time. It can be considered that the original time-domain weight α and the relay time-domain weight (1-α) are both time coefficients, then the original time-domain weight α and the relay time-domain weight (1 -α) can be derived.

Step 106, in the space domain, the original space domain weight of each pixel point in the original image and the relay space domain weight of each pixel point in the relay image are obtained.

The original spatial domain weight is the weight factor of the pixel in the original image in the spatial dimension. The relay spatial weight is the weight factor of the pixels in the relay image in the spatial dimension.

In one embodiment, the electronic device acquires the original spatial domain weight of each pixel in the input original image, and the relay spatial domain weight of each pixel in the relay image.

It can be understood that the original image is taken by the original camera, and the relay image is taken by the relay camera, and different cameras may have different fields of view. When the fields of view of the original image and the relay image are inconsistent, only the weight factors of the original image and the relay image in the time domain are obtained, then in the subsequent image obtained by fusing the original image and the relay image based on the weight factor, it is easy to appear The very obvious rectangular outline makes the displayed image unnatural when the zoom ratio enters the preset ratio range.

Therefore, this embodiment not only obtains the weights of the original image and the relay image in the time domain, but also obtains the weights of the original image and the relay image in the space domain, and subsequently fuses the images with inconsistent fields of view to obtain the target image, as shown The target image can eliminate the rectangular outline from the spatial dimension, making the displayed target image more natural when the magnification enters the preset magnification range.

Step 108, based on the pixel value, original time domain weight and original space domain weight of each pixel point in the original image, and the pixel value, relay time domain weight and relay space domain weight of each pixel point in the relay image, determine each pixel in the target image The pixel value of the target pixel.

The target image is the image obtained by fusing the original image and the relay image. The target pixel is the pixel in the target image.

The pixel value of each pixel in the target image can be calculated according to the following formula:

I(x,y)=(α _t +α _s (x,y)-α _t α _s (x,y))I _A (x,y)+(1-α _t -α _s (x,y) +α _t α _s (x,y))I _B (x,y) Formula (4)

Among them, I(x, y) is the pixel value of the pixel point whose coordinates are (x, y) in the target image, and I _A (x, y) is the pixel value of the pixel point whose coordinates are (x, y) in the original image , I _B (x, y) is the pixel value of the pixel with coordinates (x, y) in the relay image, α _t is the original time domain weight of each pixel in the original image, (1-α _t ) is the relay image The relay time-domain weight of each pixel in the original image, the original space-domain weight of the pixel with coordinates (x, y) in the original image is α _s (x, y), and the pixel with coordinates (x, y) in the relay image The relay space domain weight of is α _s (x,y).

It should be noted that when the size of the original image or the relay image is inconsistent, and some areas of the original image and the relay image overlap, and the other part does not overlap, then the non-overlapping area in the larger image will be taken as the smaller size. For non-overlapping areas in the image, the pixel value of each pixel in the target image is calculated by formula (4).

The electronic device may use a transparency (alpha) fusion process to fuse the original image and the relay image to obtain the target image. It can be understood that when the magnification is in the preset magnification range, the image displayed on the display interface gradually changes from the image taken by the original camera to the image taken by the relay camera, that is, the transparency of the image taken by the original camera changes from opaque to transparent, and the image taken by the relay camera changes from opaque to transparent. The transparency of the captured image changes from transparent to opaque.

It should be noted that, in the process of the electronic device fusing the original image and the relay image to obtain the target image, the original image is continuous, that is, the changes of the pixels at the same position in adjacent original images are continuous. Similarly, The relay images are also continuous, that is, the changes of the pixels at the same position in adjacent relay images are continuous, which can ensure that the multi-frame target images obtained by fusion are coherent in display.

Step 110, obtain the target image according to the pixel value of each target pixel point, and display the target image.

In an implementation manner, the electronic device may directly generate the target image from the pixel values of each target pixel.

In another embodiment, the electronic device may filter the pixel values of each target pixel, filter out the noise in the pixel values of each target pixel, and generate the target image from the filtered pixel values .

The electronic device obtains the original image taken by the original camera in real time, and the relay image taken by the relay camera in real time. The original image and the relay image taken at the same time can be fused to obtain the target image, and the zoom ratio is within the preset ratio range. The multi-frame target image is fused, and the multi-frame target image is displayed. It is understandable that when the magnification is within the preset magnification range, the multi-frame target images displayed on the display interface constitute a transition animation, which can more naturally show the gradual transition from the picture taken by the original camera to the picture taken by the relay camera, which will be shown soon The image displayed on the interface switches from the image captured by the original camera to the image captured by the relay camera.

In the process of displaying the target image, an automatic white balance (AWB) technology may also be combined for color management, so that the color of the displayed target image is more natural and a better fusion effect is achieved.

The above image display method obtains the original image taken by the original camera and the relay image taken by the relay camera under the condition that the zoom ratio of the image is controlled to enter the preset ratio range; The weight of each pixel, and the weight of each pixel in the relay image, then the original image and the target image can be fused from the time domain and the space domain to obtain the transition target image between the original image and the relay image, and display the The target image avoids the problem of sudden changes in the image (content, color) caused by directly switching the original image to the relay image during the process of switching from the original camera to the relay camera, and can smoothly transition from the image captured by the original camera to the relay camera , making the displayed images more natural.

In one embodiment, when the size of the original image is inconsistent with the size of the relay image, the original image and the relay image with the same size can be obtained by adjusting (resize) the size of the image, or performing interpolation processing on an image with a smaller size, Then, based on the pixel value of each pixel in the original image, the original time domain weight and the original space domain weight, and the pixel value of each pixel in the relay image, the relay time domain weight and the relay space domain weight, determine each target in the target image The step of the pixel value of the pixel point.

In one embodiment, as shown in FIG. 3 , in the spatial domain, the original spatial domain weights of each pixel in the original image and the relay spatial domain weights of each pixel in the relay image are acquired, including:

Step 302, content alignment is performed on the original image and the relay image, and an image with a smaller field of view and an image with a larger field of view are determined.

The field of view refers to the range observed by the camera. It can be understood that the original image is taken by the original camera, and the relay image is taken by the relay camera, and the observation ranges of the original camera and the relay camera are usually different, so the field of view of the original image and the field of view of the relay image are also different. Usually different.

Specifically, the electronic device can align the content of the original image and the relay image by means of translation, rotation, deformation, center positioning, and content matching. As an image with a smaller field of view, another image is used as an image with a larger field of view.

The original image can be an image with a small field of view or an image with a large field of view. Similarly, the relay image may be an image with a smaller field of view, or an image with a larger field of view.

In the case that the original image is an image with a smaller field of view and the relay image is an image with a larger field of view, the image displayed on the display interface will gradually change from the image with a smaller field of view to the image with a larger field of view, that is, the displayed zoom out on the screen. In the case that the original image is an image with a larger field of view and the relay image is an image with a smaller field of view, the image displayed on the display interface gradually changes from the image with a larger field of view to the image with a smaller field of view, that is, the displayed to zoom in on the screen.

Step 304, perform region division on the image with a smaller field of view.

It can be understood that the image with a larger field of view covers the image with a smaller field of view, and there is a part of extra area in the image with a larger field of view, which does not exist in the image with a smaller field of view. Therefore, in the process of changing the picture taken by the original camera to the picture taken by the relay camera, that is, when the zoom ratio enters the preset magnification range, the image with a smaller field of view can be completely faded to one with a larger field of view in the spatial dimension. Therefore, the image with a smaller field of view is divided into regions, and then the spatial domain weight of each pixel in the image is determined according to the image with a smaller field of view after region division.

Optionally, the electronic device may divide the field of view with a smaller field of view into nine grid areas, sixteen grid areas, or 10 areas. The specific area division method can be set as required, and is not limited here.

Step 306 , in the spatial domain, the spatial domain weights of the pixels in each region in the image with a smaller field of view and the spatial domain weights of each pixel in the image with a larger field of view are obtained.

The image with a smaller field of view is the original image or the relay image. Correspondingly, the image with a larger field of view is the relay image or the original image. In the spatial domain, the space of the pixels in each area of the image with the smaller field of view is obtained. domain weight, and the spatial domain weight of each pixel in the image with a larger field of view, that is, the original spatial domain weight of each pixel in the original image, and the relay spatial domain weight of each pixel in the relay image.

In this embodiment, the content of the original image and the relay image is aligned, the image with a smaller field of view is determined, and the image with a smaller field of view is divided into regions, so that the original spatial domain weight of each pixel in the original image can be accurately determined , and the relay spatial domain weights of each pixel in the relay image.

In one embodiment, in the spatial domain, obtaining the spatial domain weights of pixels in each region in an image with a smaller field of view and the spatial domain weights of each pixel in an image with a larger field of view includes: determining the field of view The gradient direction of each area in the smaller image; based on the gradient direction of each area, determine the spatial domain weight of the pixels in each area in the image with a smaller field of view; The spatial domain weight of the pixel point, and the spatial domain weight of each pixel point in the regions other than the corresponding regions.

The gradient direction is the direction in which a region in the original image fades to a corresponding region in the relay image. For example, the gradient direction of the upper left corner area in the original image may include a horizontal direction and a vertical direction, that is, the upper left corner area gradually changes from the horizontal direction and the vertical direction to the corresponding area in the relay image. As another example, the gradient direction of the edge middle area between the upper left corner area and the upper right corner area in the original image may include the longitudinal direction, that is, the edge middle area gradually changes from the longitudinal direction to the corresponding area in the relay image.

The image with a larger field of view includes regions overlapping with the image with a smaller field of view, and also includes regions other than the overlapping regions, that is, regions other than the corresponding regions.

Corresponding to each area in the image with a smaller field of view, the spatial domain weight of each pixel in each area corresponding to the image with a larger field of view may also be determined based on the same gradient direction. The spatial domain weight of each pixel in the area other than the corresponding area may be set to 1.

In this embodiment, the gradient direction of each region in the image with a smaller field of view is determined; based on the gradient direction of each region, the spatial domain weights of pixels in each region in the image with a smaller field of view can be accurately determined, and the obtained The spatial domain weights of each pixel point in each corresponding region in the image with a larger field of view, and the spatial domain weights of each pixel point in regions other than the corresponding regions.

In one embodiment, determining the gradient direction of each region in the image with a small field of view includes: in the image with a small field of view, the gradient directions of the corner regions at the four corners all include the horizontal direction and the vertical direction Direction, the gradient direction of the edge middle area between two adjacent corner areas includes the horizontal direction or the vertical direction; based on the gradient direction of each area, determine the spatial domain of the pixels in each area of the image with a smaller field of view Weight, including: for the corner area, obtain the area size data in the horizontal direction and the area size data in the vertical direction, and determine the spatial domain weight of each pixel in the corner area; for the middle area of the edge, obtain the area in the horizontal direction The size data or the area size data in the longitudinal direction determine the spatial domain weight of each pixel in the middle area of the edge.

The corner area refers to the area at the corner, such as the corner area of the upper left corner, the corner area of the upper right corner, the corner area of the lower left corner, and the corner area of the lower right corner. The middle area of the edge refers to the area between two adjacent corner areas, such as the area between the upper left corner area and the upper right corner area is the edge middle area, the upper left corner area and the lower left corner The area between the corner areas is the edge-middle area. The number of edge middle regions between two adjacent corner regions may be one or at least two.

Area-scale data includes the width and height of the area in which it is located.

Fig. 4 is a schematic diagram of performing region division on an image with a smaller field of view in an embodiment. 402 is an image with a larger field of view, and 404 is an image with a smaller field of view. The image with a smaller field of view is divided into regions, and the image with a smaller field of view is divided into nine square grid regions.

The spatial domain weight of each pixel in the corner area of an image with a small field of view can be calculated according to the following formula:

Among them, α(x, y) is the spatial domain weight of the pixel with coordinates (x, y) in the corner area, x is the abscissa of the pixel with coordinates (x, y), and y is the coordinates of (x ,y), the ordinate of the pixel point, band _h is the height of the corner area, and band _w is the width of the corner area.

The spatial domain weights of the pixels in the corresponding area in the image with a larger field of view can be calculated according to the above formula.

The spatial domain weight of each pixel in the middle area of the edge in the original image can be calculated according to the following formula:

Among them, α(x, y) is the spatial domain weight of the pixel with coordinates (x, y) in the middle area of the edge, y is the ordinate of the pixel with coordinates (x, y), and band _h is the middle area of the edge the height of.

The spatial domain weights of the pixels in the corresponding area in the image with a larger field of view can be calculated according to the above formula.

The spatial domain weights of the pixels in the regions other than the corresponding regions in the image with a larger field of view may be set as required, for example, set to 1.

In this embodiment, in an image with a small field of view, the gradient directions of the corner areas at the four corners all include the horizontal direction and the vertical direction, and the edge middle area between two adjacent corner areas The gradient direction includes horizontal or vertical direction; for the corner area, the area size data in the horizontal direction and the area size data in the vertical direction can be obtained to more accurately determine the spatial domain weight of each pixel in the corner area; For the middle edge region, the region size data in the horizontal direction or the region size data in the longitudinal direction can be obtained to more accurately determine the spatial domain weight of each pixel in the middle edge region.

In one embodiment, the above method further includes: when the zoom ratio is within the preset ratio range, and the number of image frames acquired continuously under the same zoom ratio is less than the preset number, sequentially displaying the target image; In the preset magnification range, and when the number of image frames acquired continuously at the same zoom magnification is greater than or equal to the preset number, adjust the zoom magnification until the zoom magnification exceeds the preset magnification range.

When the zoom ratio is within the preset ratio range, and the number of image frames acquired continuously at the same zoom ratio is less than the preset number, it means that the current zoom ratio is continuously adjusted, that is, continuously increased or continuously decreased, and the display interface shows The image is continuously zoomed in or out, and then the target image obtained by fusion of the original image and the relay image is displayed in sequence, so that the picture displayed on the display interface gradually changes from the picture taken by the original camera to the picture taken by the relay camera. Among them, the sequentially displayed target images are transition animations composed of multiple frames of target images, and the displayed transition animations can naturally gradually change from the pictures taken by the original camera to the pictures taken by the relay camera.

When the zoom ratio is within the preset ratio range, and the number of image frames acquired continuously at the same zoom ratio is greater than or equal to the preset number, it means that the current zoom ratio stays at a certain zoom ratio. It can be understood that, when the magnification is within the preset magnification range, and the number of image frames acquired continuously at the same magnification is less than the preset number, at this time the picture taken by the original camera is transitioning to the picture taken by the relay camera , if it stays at the current magnification, the target image displayed on the display interface is always the same fused image, and the fused image contains the ghost image of the original image and the relay image, and there is a problem of inaccurate image display.

Therefore, when the zoom ratio is within the preset ratio range, and the number of image frames acquired continuously under the same zoom ratio is greater than or equal to the preset number, the zoom ratio is adjusted until the zoom ratio exceeds the preset ratio range. That is to say, when the current zoom ratio stays at a certain zoom ratio, adjust the zoom ratio and continue to control the zoom ratio to increase or decrease, so that the target image displayed on the display interface is more natural until the zoom ratio Exceeded the preset magnification range.

The adjusted zoom ratio can be calculated according to the following formula:

Among them, Zoom _ctrl is the automatic zoom magnification, zoom _max is the upper limit value of the preset magnification range, zoom _min is the lower limit value of the preset magnification range, n is the number of image frames acquired after staying at the zoom magnification, and N is preset The total number of image frames acquired in the preset magnification range. Wherein, the dwell zoom ratio is the same zoom ratio at which the number of continuously acquired image frames is greater than or equal to a preset number.

In this embodiment, when the magnification is within the preset magnification interval, and the number of image frames acquired continuously at the same zoom magnification is less than the preset number, the target images are displayed sequentially, which can make the target images displayed on the display interface more natural ; When the zoom ratio is within the preset ratio range, and the number of image frames acquired continuously under the same zoom ratio is greater than or equal to the preset number, adjust the zoom ratio and control the zoom ratio to continue to increase or decrease, which can avoid displaying The problem of ghosting caused by displaying the same target image for a long time in the interface can also make the displayed target image more natural.

Fig. 5 is a schematic diagram of adjusting zoom ratio in an embodiment. The preset magnification range is 0.8X-1.2X. When the zoom magnification is within the preset magnification range, and the number of image frames acquired continuously at the same zoom magnification is greater than or equal to the preset number, adjust the zoom magnification until the zoom magnification exceeds Preset magnification range.

In an embodiment, adjusting the zoom ratio includes: acquiring a zoom direction of the zoom ratio and a zoom speed of the zoom ratio; and adjusting the zoom ratio according to the zoom direction and the zoom speed.

The zoom direction is the direction of the zoom ratio during zooming. The zooming direction may be from large to small, or from small to large. When the zoom ratio of the image is zoomed in the direction from large to small, that is, the image is reduced, and the field of view of the image becomes larger. When the zoom ratio of the image is zoomed in a direction from small to large, that is, the image is enlarged, and the field of view of the image becomes smaller.

The electronic device obtains the historical zooming direction before the moment of determining the dwell zoom ratio, and takes the historical zoom direction as the zoom ratio zoom ratio; wherein, the dwell zoom ratio is the same zoom ratio at which the number of continuously acquired image frames is greater than or equal to a preset number .

The electronic device uses the historical zooming direction as the zooming direction when continuing to adjust the zooming ratio, so that the zooming ratio can be adjusted according to the trend of the historical zooming direction, and the displayed target image is more natural.

The zoom speed is the speed of the zoom factor during zooming. The larger the zoom speed, the faster the image will be zoomed in or zoomed out per unit time. Zoom speed can be set as needed. The zoom speed measures how quickly the transition animation formed by each target image disappears when the zoom ratio is within the preset ratio range.

The preset number of image frames acquired within the preset magnification range is obtained, and the zooming speed is determined through the corresponding relationship between the number of image frames and the zooming speed.

In this embodiment, the electronic device acquires the zooming direction of the zooming ratio and the zooming speed of the zooming ratio; according to the zooming direction and the zooming speed, the zooming ratio can be adjusted more accurately.

In one embodiment, as shown in Figure 6, the above method also includes:

Step 602, during the process of controlling the zoom ratio to continue adjusting, detect the current automatic zoom ratio in real time.

The automatic zoom ratio is a zoom ratio automatically adjusted by the electronic device when the zoom ratio is within a preset ratio range and the number of image frames acquired continuously at the same zoom ratio is greater than or equal to the preset number.

Step 604, if it is detected that the user controls the zoom ratio of the image, determine the user zoom ratio currently controlled by the user.

User magnification is a user-controlled magnification.

When the electronic device controls the zoom ratio and continues to adjust, the user may control the zoom ratio to zoom the image. In the event that the electronic device detects that the user controls the zoom ratio of the image, the electronic device determines the user zoom ratio currently controlled by the user.

Step 606, in the case that both the automatic zoom ratio and the user zoom ratio are greater than the stop zoom ratio, or both are smaller than the stop zoom ratio, determine the target zoom ratio with the larger difference from the user zoom ratio and the automatic zoom ratio as the target zoom ratio Magnification; the dwell zoom ratio is the same zoom ratio at which the number of image frames acquired continuously is greater than or equal to the preset number.

In the case that both the automatic zoom ratio and the user zoom ratio are greater than the stop zoom ratio, or both are smaller than the stay zoom ratio, it means that the direction of the electronic device to adjust the zoom ratio is consistent with the direction in which the user controls the zoom ratio. The larger difference is used as the target zoom ratio.

It can be understood that the purpose of the electronic device to determine the target zoom ratio with a larger difference from the dwell zoom ratio is to avoid the display of repeated images in the display interface when the target zoom ratio is determined to be smaller than the stay zoom ratio. Condition.

For example, the dwell zoom ratio of the electronic device is 1X. During the process of adjusting the zoom ratio, the electronic device detects in real time that the current automatic zoom ratio is 1.5X, and the user zoom ratio currently controlled by the user is 1.2X. Both the zoom ratio and the user zoom ratio are greater than the stop zoom ratio. If the difference between the zoom ratio and the stop zoom ratio is smaller, that is, the user zoom ratio of 1.2X is used as the target zoom ratio, then the zooming process of the screen displayed on the display interface is zoomed from 1X Going to 1.5X and back to 1.2X shows a repeating picture. If the larger difference from the stop zoom ratio is used as the target zoom ratio, that is, the automatic zoom ratio of 1.5X is used as the target zoom ratio, then the zoom process of the screen displayed on the display interface is zoomed from 1X to 1.5X, and 1.5X is used as the target The magnification continues to scale for a more natural image display.

The target zoom ratio can be calculated according to the following formula:

Wherein, Zoom _resilt is the target zoom ratio, Zoom _ctrl is the automatic zoom ratio, Zoom _usr is the user zoom ratio, Zoom is the dwell zoom ratio, A=(Zoom _ctrl -Zoom)(Zoom _usr -Zoom), at A>0 In this case, it means that both the automatic zoom ratio and the user zoom ratio are greater than the stop zoom ratio, or both are smaller than the stop zoom ratio, (Zoom _ctrl -Zoom)(Zoom _usr -Zoom)<0 means that the automatic zoom ratio and the user zoom ratio are in between, One of them is greater than the dwell magnification, and the other is smaller than the dwell magnification.

Step 608, performing image display based on the target zoom ratio.

In this embodiment, in the process of adjusting the zoom ratio, the current automatic zoom ratio is detected in real time; when the zoom ratio of the image controlled by the user is detected, the user zoom ratio currently controlled by the user is determined; When both the user zoom ratio and the user zoom ratio are greater than the stay zoom ratio, or both are smaller than the stay zoom ratio, from the user zoom ratio and the automatic zoom ratio, determine the larger difference from the stay zoom ratio as the target zoom ratio, which can make the image display more accurate. nature.

In one embodiment, the above method further includes: under the condition that one of the automatic zoom ratio and the user zoom ratio is larger than the dwell zoom ratio, and the other is smaller than the dock zoom ratio, performing image display based on the user zoom ratio.

In the case of the automatic zoom ratio and the user zoom ratio, one of which is greater than the stop zoom ratio and the other is smaller than the stop zoom ratio, it means that the zoom direction of the automatic zoom ratio is opposite to that of the user zoom ratio, and it is directly based on the user zoom ratio for image display.

For example, the dwell zoom ratio of the electronic device is 1X. During the process of adjusting the zoom ratio, the electronic device detects in real time that the current automatic zoom ratio is 1.5X, and the user zoom ratio currently controlled by the user is 0.8X, indicating that the user wants to zoom out. The image is displayed based on the user's zoom ratio, and the displayed image is more in line with the user's needs.
