[0061] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described below by way of example do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0062] With the development of mobile phone imaging technology, users increasingly rely on mobile phones to capture images of various scenes, such as the moon. In actual applications, when photographing the moon, users need to use high-power zoom to make the moon large enough in the image. However, in an unstable state such as high-position zoom, a slight shake of the user's hand will cause the moon to move out of the preview interface, making it impossible to obtain a satisfactory moon image.

[0063] In the process of implementing the embodiment of the present disclosure, after careful analysis, the inventors found that: the image processor will cut out an image P1 of a corresponding size from the original image P0 (whose size is the same as the size of the image sensor) collected by the image sensor according to the magnification N of the camera module, and then display it on the display to achieve the effect of magnification N times. Figure 1 Then, during the above-mentioned cutting process, the image processor will always use the preset position of the original image (such as the center position O) as the center position of the displayed image, so that the alignment area does not match the display area. In addition, due to the shaking of the user's hand, the moon is often moved out of the display area. Figure 1 As shown in FIG. 1 , when the magnification is increased from N times to N1 times, the moon M is moved out of the cropping area and cannot be displayed on the preview image, which reduces the shooting experience.

[0064] In order to solve the above technical problems, the disclosed embodiment provides a method for obtaining a moon image, the inventive concept of which is to obtain the position data of the moon in the original image; taking the position data as the center position, combined with the current actual zoom factor of the camera module, the moon image is cut out from the original image, wherein the center area of ​​the moon image contains the moon. In this way, in this embodiment, the alignment area can be matched with the display area to prevent the moon from being moved out of the display area, which is conducive to improving the user's shooting experience.

[0065] Figure 2 1 is a flow chart of a method for obtaining a moon image according to an exemplary embodiment, which is applicable to an electronic device, which may include a smart phone, a personal computer, or a server. Figure 2 , a method for obtaining a moon image, comprising steps 21 to 22:

[0066] In step 21, the position data of the moon in the original image is obtained.

[0067] In this embodiment, a camera module is provided on the electronic device. When a user triggers a "camera" APP on the system interface of the electronic device, the camera module can be turned on and controlled to be in a shooting state.

[0068] During the shooting process, the user can operate the lens of the camera module, for example, by rotating it clockwise or counterclockwise to enlarge or reduce the zoom factor of the camera module. Combined with the preview image on the display screen of the electronic device, the user can determine whether the size of the moon meets the user's expected size at the current actual zoom factor, and stop adjusting until it meets the expected size.

[0069] In one embodiment, a preset image recognition algorithm may be stored in the electronic device, such as a recognition algorithm based on machine learning, such as a convolutional neural network, or a recognition algorithm based on feature matching, such as a feature extraction algorithm ORB (Oriented Fast and Rotated Brief), a scale-invariant feature transform SIFT (Scale-invariant feature transform), etc., and a suitable image recognition algorithm may be selected according to the specific scenario, which is not limited here. When it is detected that the user triggers the shooting operation, the electronic device may use the above-mentioned preset image recognition algorithm to identify the objects contained in the original image, such as people, scenery or the moon. In this way, when the moon is included in the original image, the position data of the moon can be obtained. The above-mentioned position data may include the horizontal and vertical coordinates of the center position of the moon in the original image, and may also include data such as the width and length of the moon, which are not limited here.

[0070] In one embodiment, the electronic device may also determine whether the camera module meets a preset condition before determining the position data, and then execute step 21 after the preset condition is met. The preset condition includes any one of the following: 1) the current shooting mode is the moon mode, 2) in the moon mode and the current zoom factor of the camera module exceeds the preset factor threshold.

[0071] In one example, when the preset condition is that the current shooting mode is the moon mode, the electronic device determines whether the camera module meets the preset condition, including: the electronic device can obtain the current shooting mode of the camera module. Figure 3In step 31, the electronic device can use a preset image recognition algorithm to identify the original image and obtain the object contained in the original image; in step 32, when there is a moon among the objects contained in the original image, it is determined that the current shooting mode of the camera module is the moon mode; when there is no moon in the original image, the current shooting mode can be determined according to the light of the current shooting scene or the historical shooting mode before the camera module is turned on. The electronic device can determine that the preset conditions are met when the current shooting mode of the camera module is the moon mode; otherwise, if the preset conditions are not met, shooting can be performed according to the existing shooting mode. For example, the acquisition method can be to read a shooting mode identifier with a value of 1 and use the corresponding shooting mode as the current shooting mode. The above-mentioned shooting modes may include moon mode, portrait mode, night scene mode, etc. When the user adjusts the shooting mode of the camera module to a certain mode, the shooting mode identifier is set to 1.

[0072] In another example, when the preset condition is that the current shooting mode is the moon mode, the electronic device determines whether the camera module meets the preset condition, see Figure 4 , including: in step 41, the electronic device can obtain the current shooting mode of the camera module, and the method for determining the shooting mode can refer to the content in the previous paragraph. In step 42, when the current shooting mode is the moon mode, the current actual zoom multiple of the camera module is obtained. In step 43, when the actual zoom multiple exceeds the preset multiple threshold, it can be determined that the camera module meets the preset condition, and step 21 can be executed. Otherwise, the preset condition is not met, and shooting can be performed according to the existing shooting mode.

[0073] The above-mentioned preset magnification threshold can be determined according to the critical zoom magnification of at least two lenses in the camera module. For example, the magnification of the wide-angle lens is 1.0-3.0, and the magnification of the telephoto lens is 3.0-5.0, then the preset magnification threshold can be set to 3.0. Of course, the above-mentioned preset magnification threshold can also be determined in a big data manner. By counting the zoom magnifications of various camera modules and the corresponding effects when shooting the moon, the preset magnification threshold is determined. For example, the zoom magnification corresponding to the best shooting effect is used as the preset magnification threshold. It is understandable that various settings of the preset magnification threshold fall within the protection scope of the present disclosure as long as the quality of the moon image can be improved. In this example, the value range of the preset magnification threshold can be 3.0~5.0.

[0074] It should be noted that, in this embodiment, by setting a preset zoom factor threshold, it is possible to prevent the zoom factor from being too large or the user from shaking, which may affect the quality of the moon image, and it is also possible to reduce the amount of calculation required for data processing by the electronic device.

[0075] In one embodiment, see Figure 5In step 51, after acquiring the position data, the electronic device can cut out a preview image of a size corresponding to the actual zoom factor from the original image. In step 52, the electronic device can control the display screen to display the preview image, so that the user can see the captured image in time.

[0076] In step 22, a moon image is acquired based on the position data and the current actual zoom factor of the camera module, wherein the central area of ​​the moon image includes the moon.

[0077] In this embodiment, the electronic device can determine the moon image based on the moon position data and the current actual zoom factor of the camera module, see Figure 6 , including: in step 61, the electronic device can determine the area of ​​interest in the original image based on the position data and the current actual zoom multiple of the camera module, the effect is as follows Figure 7 The moon in the original image is located in the center of the region of interest, and the center position O1 of the moon coincides with the center position of the region of interest. In step 62, the electronic device may perform image post-processing, such as auto focus, auto white balance, auto exposure, etc., on the portion of the original image located in the region of interest, thereby obtaining a moon image.

[0078] At this point, by obtaining the position data of the moon in the original image in the embodiment of the present disclosure, the moon image can be obtained according to the position data and the current actual zoom factor of the camera module, and the moon is located in the central area of ​​the moon image, so that the alignment area is matched with the display area, avoiding the moon from being moved out of the display area in the case of high focal length, which is beneficial to improving the user's shooting experience.

[0079] The following describes the above-mentioned method for obtaining the moon image in conjunction with an embodiment in which a user uses a mobile phone to take a moon image, including:

[0080] When the user uses the phone's camera function and turns on the moon mode or automatically switches to the moon mode, the following functions can be enabled:

[0081] When it is detected that the actual zoom ratio of the camera module adjusted by the user exceeds the preset zoom threshold, the processor will no longer output images with higher zoom ratios. Any zoom ratio set by the user that exceeds this threshold will no longer cause the ISP to increase the output image ratio.

[0082] The original image is input into the preset moon mode algorithm, and the moon mode algorithm identifies the position data of the moon in the original image. At the same time, the moon mode algorithm cuts out an image (i.e., a preview image) that conforms to the current actual zoom ratio from the original image with the above position data as the center position, and controls the display screen to display the preview image.

[0083] The moon mode algorithm may also send the position data and the original image to a preset 3A algorithm, which is used to perform image post-processing on the input image, such as auto focus, auto white balance, and auto exposure.

[0084] The 3A algorithm defines a region of interest (ROI) in the original image based on the position data of the moon in the original image determined by the moon mode algorithm, and then performs 3A processing on part of the image in the ROI area to obtain a moon image with the moon in the center area. That is, in this example, the moon is always used as the ROI, so that the obtained parameters are stable and the image quality of the moon is high.
