Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.

Currently, users often take pictures with a camera on an electronic device. In some scenarios, the user is required to move the mirror to move the camera up, down, left or right in parallel to obtain a better effect. However, during the process of moving the mirror, the shaking of the hand of the user can cause the picture to shake, which affects the video viewing.

Therefore, the embodiment of the disclosure provides an image shooting method, which is conceived to be characterized in that a mirror-moving key is arranged on an electronic device, and if the mirror-moving key is triggered, the electronic device adjusts a cutting position to move a cut target image after adjustment towards a direction corresponding to the mirror-moving key compared with the cut target image before adjustment, so as to achieve an effect of virtually moving the electronic device towards the direction corresponding to the mirror-moving key. In the embodiment, the user does not need to move the electronic equipment, so that the shaking of the picture caused by shaking can be avoided, and the improvement of the quality of the image and the shooting experience are facilitated.

Fig. 1 is a diagram illustrating an application scenario according to an exemplary embodiment, and referring to fig. 1, a camera (not shown) is disposed on an electronic device 10, and the camera may have a display interface 11 and a non-display interface 12 outside the display interface 11 during operation. The display interface 11 may be provided with a mirror shift key 13, where the mirror shift key 13 may include at least one of the following: a first move mirror button 131 representing an upward pan, a second move mirror button 132 representing a downward pan, a third move mirror button 133 representing a leftward pan, and a fourth move mirror button 134 representing a rightward pan. Certainly, in an embodiment, the mirror shift key may be set as a physical or virtual key such as a knob, a rocker, and the like, and in the case that the translation direction can be determined, the corresponding scheme falls into the protection scope of the present application.

In addition, some other function keys may be set in the non-display interface 12, for example, a front/back lens switching key, a photo album browsing key, a video recording key, a shooting key, etc., and a technician may set the function keys according to a specific scene, which is not limited herein.

The user can trigger the mirror shift key, and the triggering mode can include single-clicking or long-time pressing, for example, the electronic device can execute one image shooting method, and if the electronic device is pressed for a long time, the electronic device can execute one image shooting method for multiple times, and the direct mirror shift key is released. Of course, the triggering mode and the electronic device executing one image shooting method may be adjusted according to a specific scene, and the corresponding schemes all fall within the scope of the present application.

Fig. 2 is a flowchart illustrating an image capturing method according to an exemplary embodiment, which may be applied to the application scenario illustrated in fig. 1. Referring to fig. 2, an image capturing method includes steps 201 and 202, in which:

in step 201, in response to a mirror shifting key on the electronic device being triggered, acquiring an original image with a preset first size; the first size is larger than a second size crop box on the electronic device.

In this embodiment, the processor in the electronic device may monitor whether the mirror shift key is triggered. The monitoring mode can include: for example, the mirror shift key may correspond to a thread, and the processor may obtain the state (triggered or not triggered) of the mirror shift key by communicating with the thread. For another example, the mirror shift key may correspond to an interrupt instruction, and when triggered, the interrupt instruction may be generated and sent to the processor, so that the processor may determine to monitor that the mirror shift key is triggered.

In one embodiment, the shift keys may include a first shift key 131 to indicate an upward shift, a second shift key 132 to indicate a downward shift, a third shift key 133 to indicate a leftward shift, and a fourth shift key 134 to indicate a rightward shift, with the effect as shown in fig. 1.

It should be noted that, in this embodiment, the first mirror shift key 131, the second mirror shift key 132, the third mirror shift key 133, and the fourth mirror shift key 134 may respectively correspond to different threads or different interrupt instructions, that is, the processor may determine the first mirror shift key 131, the second mirror shift key 132, the third mirror shift key 133, or the fourth mirror shift key 134 when receiving the signal. Of course, the first mirror shift key 131, the second mirror shift key 132, the third mirror shift key 133, and the fourth mirror shift key 134 may also correspond to the same thread or the same interrupt instruction, that is, the processor needs to analyze the signal when receiving the signal, and then determines the first mirror shift key 131, the second mirror shift key 132, the third mirror shift key 133, or the fourth mirror shift key 134 according to the analysis result. In the case that the processor can identify the mirror shift key, the corresponding scheme falls into the protection scope of the application.

In this embodiment, the image in the crop box can be displayed as an image taken each time by the display interface in consideration that the size of the image sensor in the camera is larger than the second size of the crop box on the electronic device, and the size of the crop box is completely matched with the size of the display interface 11.

It should be noted that, in this embodiment, the crop box may be set in advance, and the size of the crop box is completely the same as the size of the display interface of the electronic device, that is, the size of the crop box is the second size. It should be noted that, the crop box in this embodiment is only used for exemplary illustration, and in practical applications, the crop box may be a rectangle formed by only four anchor points, or a rectangle formed by one anchor point, a width line and a length line, or the crop box is a minimum rectangle containing the width line and the length line whose center points are overlapped. In addition, in this embodiment, the crop box may be displayed in the display interface, or may not be displayed in the display interface, which may achieve corresponding effects, and the corresponding solutions fall within the scope of protection of the present application.

For this reason, the processor in this embodiment may control the image sensor in the camera to acquire the original image of the first size first, and the effect is as shown in fig. 3.

It should be noted that the first size in this embodiment may be preset, for example, the second size is increased to the first size while the aspect ratio is kept unchanged. As another example, the size of the image sensor is directly taken as the first size. For another example, after the mirror shifting key is determined, the width of a certain distance is increased on the second size according to the direction corresponding to the mirror shifting key, and then the first size is obtained; wherein the increased width is at least greater than the distance that the subsequent translation is required. All the above modes fall into the protection scope of the present application.

In step 202, after the cropping frame is translated in the direction corresponding to the mirror-moving key, determining a partial image of the original image in the cropping frame as a target image obtained by the current shooting.

In this embodiment, after the mirror shift key is triggered, under the condition that the user clicks or presses the mirror shift key for a short time, that is, under the scene where the clipping box translation distance is small, the processor may translate the clipping box on the original image, and determine a partial image of the original image located in the clipping box as the target image obtained by the current shooting.

In this embodiment, when the user presses the mirror-moving key for a long time, the electronic device may continue to move the cropping frame based on the previous cropping position, so that the position translation distance between the current position of the cropping frame and the triggered time is longer. It should be noted that, when the mirror-moving key is triggered for a long time, the electronic device may perform a translation on the crop box every a period of time (e.g., 33.3ms) from when the mirror-moving key is triggered, where an initial position of the translation is a last cropping position, and a distance of each translation of the crop box may be a set value (e.g., several centimeters, which is adjustable), so that the electronic device may perform the translation multiple times continuously within the triggered time period, and may acquire one image at each time. For the user, the effect of uniform mirror shift can be obtained.

Referring to fig. 4, after the mirror shift key is triggered, or after the mirror shift key is triggered for a certain period of time, or after the mirror shift key is translated for a certain number of times, the processor may translate the cropping frame on the original image, and then determine whether the cropping frame is shifted out of the original image (corresponding to step 401 in fig. 4). If not, the processor may determine that a partial image of the original image within the crop box is a target image obtained by the current shooting (corresponding to step 402 in fig. 4). Taking the first mirror-moving key 131 as an example, referring to fig. 5, after cropping, the target object "a" is displayed in the box, and after cropping, the target object "a" is displayed below the box, so as to achieve the effect of virtually translating the electronic device upward.

Referring to fig. 6, if the cropping frame moves out of the original image, the processor may control the lens to adjust the current focal length to the target focal length (corresponding to step 601 in fig. 6). Then, when the lens is located at the target focal length, the step of acquiring the original image of the preset first size (corresponding to step 602 in fig. 6) is performed again, i.e., the step 201 is returned. In the embodiment, whether the cutting frame exceeds the original image or not is judged, so that the target image obtained every time does not contain a pure white or pure black invalid area, and the effect of shooting every time is improved. The pure white or pure black invalid area is a partial image obtained by pixel supplementation of the exceeding area after the cutting frame exceeds the original image.

It should be noted that, in this embodiment, the focal length variation of the lens from the current focal length to the target focal length may be determined according to the translation distance of the cropping frame, and the determination manner may refer to the related content of the focal length and the imaging area in the related art, which is not described herein again. In practical application, a translation distance and target focal length correspondence table may be preset, and the processor may query the target focal length from the translation distance and target focal length correspondence table according to the translation distance of the crop box.

In this embodiment, when the mirror shift key is pressed for a long time, wherein the long press is longer than a set time period, for example, 33.3ms, referring to fig. 7, the processor may iterate step 201 and step 202 in response to the mirror shift key being continuously triggered until the mirror shift key is released (corresponding to step 701 in fig. 7). In this embodiment, by pressing the mirror-moving key for a long time, images in the display interface can be translated in a linked manner (the direction is opposite to the moving direction of the electronic device), so that the effect of taking images by moving the mirror is achieved.

In this embodiment, referring to fig. 8, the processor further monitors whether the mirror shift key is released, and after monitoring that the mirror shift key is released, returns the crop box to the default position in the original image in response to the mirror shift key being released (corresponding to step 801 in fig. 8). For example, when the mirror shift key is released, the processor may keep the current position of the cropping frame in the current frame image, and then adjust the focal length or angle of the lens so that the default position of the cropping frame in the next frame image corresponds to the current position in the current frame. If the cropping frame is at the default position, the central point of the cropping frame is overlapped with the central point of the original image, and the cropping frame is translated when the mirror is moved, and the central point of the cropping frame is offset from the central point of the original image. After the lens shifting key is released, the central point of the next frame image needs to be aligned and overlapped with the central point of the cutting frame, and the alignment mode can be used for adjusting the focal length or angle of the lens. In this embodiment, the cropping frame is restored to the default position in the original image, which can facilitate the next mirror-shifting operation.

To this end, in the embodiment of the present disclosure, an original image of a preset first size is acquired by responding to a trigger of a mirror shift key on an electronic device; wherein the first size is larger than a second size of a crop box on the electronic device; then, after the cropping frame is translated in the direction corresponding to the mirror shifting key, the partial image of the original image in the cropping frame is determined as the target image obtained by the shooting. It is obvious that, in this embodiment, the target image is obtained by moving the cropping frame in the original image, and the effect that the target image moves relative to the image before the mirror moving key is triggered is achieved, that is, the mirror moving effect can be achieved without moving the electronic device by the user in this embodiment, the problem of picture shaking caused by hand shaking of the user does not occur, and the shooting experience is favorably improved.
