Referring to fig. 1, a flow of some embodiments of an image processing method according to the present disclosure is shown. As shown in fig. 1, the image processing method includes the steps of:

step 101, acquiring an initial cross-map acquired by using at least two transverse cameras.

In this embodiment, the vertical screen apparatus has at least two cameras that are vertical and horizontal. Wherein, the vertical screen may be a screen for vertically displaying contents. The at least two cameras arranged horizontally may be at least two cameras arranged horizontally.

The vertical or lateral direction may be a direction relative to a portion of the portrait screen device. As an example, if the vertical screen device is a learning desk lamp for a user to learn, the above-described vertical or lateral direction may be a direction relative to a lamp post of the learning desk lamp.

In this embodiment, the execution subject of the image processing method may acquire the initial cross-sectional view acquired by using the above-described at least two cameras.

The initial cross-map may be a cross-map taken with the at least two cameras described above. In some scenarios, the initial cross-plot may be a cross-plot taken for a book. Typically, an initial cross-plot with a wider field of view can be acquired with at least two cameras positioned in a landscape orientation.

Step 102, based on the current image display mode, the initial cross-map is converted into a first target display image suitable for being displayed in the vertical screen.

In this embodiment, the execution subject may transform the initial cross-map into the first target display image suitable for display in the vertical screen based on the current image display manner.

The image display method may be a method of displaying an image on the vertical screen. For example, the image display mode may be a landscape or portrait display mode.

The first target display image may be a cross-view or a vertical view suitable for display in the vertical screen described above.

Step 103, displaying a first target display image in the vertical screen.

In this embodiment, the execution body may display the first target display image in the vertical screen.

Thus, the initial transverse diagram acquired by at least two transverse cameras can be converted into a transverse diagram or a vertical diagram suitable for being displayed in the vertical screen and displayed.

In this embodiment, after the initial cross-image is acquired by using at least two cameras arranged horizontally, the acquired initial cross-image may be converted into a first target display image suitable for displaying on the vertical screen in combination with the current image display mode, and the first target display image may be displayed on the vertical screen. On the one hand, the flexibility of the vertical screen equipment for collecting images can be improved by using the at least two transverse cameras. On the other hand, by combining the current image display mode, the first target display image is displayed in the vertical screen, so that the flexibility of displaying the image to the user by the vertical screen equipment can be improved.

The scheme described in the embodiment can be applied to camera calling interfaces provided by systems of various versions. Therefore, the scheme described in the embodiment has higher compatibility.

In some embodiments, the image display mode indicates a landscape display image and/or a portrait display image.

By selecting different image display modes, the horizontal drawing or the vertical drawing can be displayed in the vertical screen.

If the current image display mode indicates a landscape display image, the obtained first target display image is still a landscape image with a wider field of view. At this time, the vertical screen device can display the target display image with a wider field of view.

If the current image display mode indicates a vertical display image, the obtained first target display image is a vertical image. At this time, in the case where the initial cross-plot is acquired, the portrait screen apparatus is still able to display the target display image in such a manner that the portrait plot is displayed.

In some embodiments, the execution subject may execute the image processing method according to the flow shown in fig. 2. Step 201 and step 204 are similar to step 101 and step 103 in the embodiment shown in fig. 1, and are not described herein.

Step 202, if the currently adopted image display mode indicates to display an image horizontally, scaling the initial horizontal drawing into a first horizontal drawing suitable for displaying on the vertical screen as a first target display image.

As an example, referring to fig. 3A, the above-described execution subject may zoom out the initial cross-plot 301 into a first cross-plot 302 suitable for display in the vertical screen 303 as the first target display image. Further, the execution subject may display the first target display image in the vertical screen 303.

Thus, by enlarging or reducing the initial cross-plot, a first cross-plot suitable for display in the above-described vertical screen is obtained, and the first cross-plot is displayed in the above-described vertical screen. At this time, the object display image with a wider visual field range can be displayed in the vertical screen by the vertical screen device.

In step 203, if the currently adopted image display mode indicates a portrait display image, the initial horizontal drawing is cut into a first portrait suitable for being displayed on the portrait screen, and the first portrait is used as a first target display image.

As an example, referring to fig. 3B, the above-described execution subject may crop the initial cross-plot 301 into a first vertical plot 304 suitable for display in the vertical screen 303 as a first target display image. Further, the execution subject may display the first target display image in the vertical screen 303.

Thus, by cropping the acquired initial cross-sectional view, a first vertical view suitable for display in the above vertical screen is obtained, and the first vertical view is displayed in the above vertical screen.

In some embodiments, the execution body may crop the initial cross-diagram into a first vertical diagram suitable for display in the vertical screen according to a flow shown in fig. 4, which includes the following steps.

Step 401, determining a vertical drawing clipping length and a vertical drawing clipping width based on the vertical drawing clipping condition.

The vertical drawing cutting condition is a condition set for cutting the above-described initial horizontal drawing into a vertical drawing. The vertical drawing clipping conditions include: the aspect ratio of the initial cross-sectional view is equal to the cut aspect ratio, and the width of the initial cross-sectional view is different from the cut length of the vertical view by a predetermined length.

The above-mentioned cut aspect ratio is the ratio of the vertical cut length to the vertical cut width. The predetermined length may be set according to actual requirements.

It will be appreciated that with the aid of the above described vertical view clipping conditions, the vertical view clipping length and vertical view clipping width can be determined on the basis of knowing the length and width of the above described initial horizontal view.

Step 402, determining a clipping start point.

The clipping start point is a start point of clipping the first vertical drawing from the above-described initial horizontal drawing.

Step 403, cutting the initial horizontal drawing into a first vertical drawing with length and width being the vertical drawing cutting length and vertical drawing cutting width respectively, with the cutting start point as a starting point.

In some cases, the execution body may select a point from a long side of the initial horizontal drawing as a clipping start point, and then clip the initial horizontal drawing into a first vertical drawing having a length and a width that are the vertical drawing clipping length and the vertical drawing clipping width, respectively, with the clipping start point as a starting point.

By setting the aspect ratio of the initial horizontal drawing to be equal to the clipping aspect ratio, the proportion of the clipped first vertical drawing to the image of the initial horizontal drawing can be consistent, so that the clipping first vertical drawing can not be stretched. Further, on the basis of the initial cross-plot being acquired, the first cross-plot, in which no image stretching has occurred, can still be displayed in the portrait of the portrait device. Thus, the effect of displaying the target display image by means of the vertical drawing can be improved.

In some embodiments, the predetermined length is 0.

It will be appreciated that a predetermined length of 0 means that the width of the initial cross-plot described above is equal to the cut length of the vertical plot.

As an example, referring to fig. 5, the initial cross-plot 501 has a length and width of L1 and W1, respectively, assuming a vertical plot cut length and vertical plot cut width of L2 and W2, respectively. If the aspect ratio of the initial cross-plot 501 is preset to be equal to the cropping aspect ratio (i.e., ) And the width of the initial cross-plot 501 is equal to the vertical-plot cut length (i.e., w1=l2), then the vertical-plot cut length l2=w1, the vertical-plot cut width +.>The execution body may determine a clipping start point 502 from the long side of the initial cross-diagram 501, and further clip the initial cross-diagram 501 into a first vertical diagram 503 having a length and a width L2 and W2, respectively, with the clipping start point 502 as a start point.

In some embodiments, the execution body may determine the clipping start point in the following manner.

First, the formula is usedAnd determining the coordinate value of the horizontal axis of the cutting start point. Wherein X represents a horizontal axis coordinate value of a cutting start point to be determined, p is a positive number greater than 0 and less than 1, L1 represents a length of the initial horizontal drawing, W2 represents a vertical drawing cutting width, and X0 represents a horizontal axis offset of the initial horizontal drawing.

The value of p can be set according to actual requirements. The horizontal axis offset is an image offset of the initial horizontal drawing on the horizontal axis.

Specifically, the execution body may determine the coordinate value of the horizontal axis of the clipping start point by substituting the values of the respective parameters into the formula.

In the second step, the vertical axis coordinate value of the clipping start point is determined by using the formula y=y0+q. Wherein Y represents the vertical axis coordinate value of the cutting start point to be determined, Y0 represents the vertical axis offset of the initial horizontal diagram, and Q represents the preset offset.

The preset offset may be set (e.g., set to 0) according to actual requirements. The vertical axis offset is an image offset of the initial horizontal drawing on the vertical axis.

Specifically, the execution body may determine the vertical axis coordinate value of the clipping start point by substituting the values of the respective parameters into the formula.

It will be appreciated that if the initial cross-plot does not have an image shift on the horizontal axis, the horizontal axis shift amount is 0. Similarly, if the initial horizontal drawing does not have an image shift on the vertical axis, the vertical axis shift amount is 0.

And thirdly, taking a point indicated by coordinates formed by the coordinate values of the horizontal axis and the coordinate values of the vertical axis as a cutting starting point.

As an example, if it is determined that the horizontal axis coordinate value and the vertical axis coordinate value are x and y, respectively, the point indicated by the coordinates (x, y) is a clipping start point.

Thus, the clipping start point is accurately determined by comprehensively considering the vertical clipping width, the length of the initial horizontal drawing, the image offset of the initial horizontal drawing, and the like. Thereby, the accuracy of cutting out the first vertical drawing from the above-described initial horizontal drawing is improved.

In some embodiments, the execution body may execute the instruction in the following manner, where p isAnd/or Q is 0.

Optionally, p isQ is 0. It can be derived from this that->Y=y0. At this time, a cut-out start point may be determined from the long side of the initial cross-plot, and a first vertical plot, in which no image stretching occurs, may be cut out from the center region of the initial cross-plot.

Optionally, p isThe above Q is 0, and the predetermined length is set to 0. It can be derived from this that->Y=y0, l2=w1 (i.e., the vertical drawing cut length L2 is equal to the width W1 of the above-described initial horizontal drawing). In this case, the first vertical drawing, which is cut out from the center area of the initial horizontal drawing and has the same length as the width of the initial horizontal drawing and does not undergo image stretching, can be realized. As an example, referring to fig. 6, a first vertical drawing 503 having a length W1 and no image stretching occurs is cut out from a central area of an initial horizontal drawing 501 with a cut-out start point 502 as a start point.

In some embodiments, the first target display image is a first portrait. After displaying the first target display image in the vertical screen, the execution body may further execute the following steps.

Specifically, in response to a received image capturing request instruction to capture a cross-plot, the first target display image is rotated into a second cross-plot, and the second cross-plot is captured.

In some scenes, in response to an image capturing operation by a user, the image capturing application may transmit an image capturing request to the execution subject described above.

In some scenarios, the above-described execution subject may rotate the first target display image by a predetermined angle (e.g., 90 degrees) in a predetermined direction (clockwise or counterclockwise) to rotate the first target display image into the second cross-plot.

If the first target display image displayed on the vertical screen is the first vertical image, the horizontal image is directly shot, and the shot image may be distorted.

Therefore, the first target display image is rotated to be the second transverse diagram, and then the second transverse diagram is shot, so that the shot image is ensured not to be distorted. Thus, when the first target display image displayed on the above-described vertical screen is the first vertical image, even if the image capturing request instructs to capture the horizontal image, an image which does not suffer from distortion can be captured.

In some embodiments, the above-described execution subject may further execute the following steps after the second cross-diagram is taken.

Specifically, the second horizontal drawing is rotated to a first vertical drawing, and the first vertical drawing is stored as a target photographed image.

In some cases, the above-described execution body may rotate the second transverse chart by a predetermined angle in a direction opposite to the predetermined direction to rotate the photographed second transverse chart into the first vertical chart.

It is not difficult to find that the photographed second horizontal drawing does not coincide with the first target display image (i.e., the first vertical drawing) displayed in the vertical screen. Therefore, the shot second transverse diagram is rotated to be the first vertical diagram, and then the first vertical diagram is stored as the target shot image, so that the target shot image can be ensured to be consistent with the first vertical diagram displayed to a user through the vertical screen.

In a first step, in response to a received video recording request indicating that a recorded video frame is a video of a horizontal drawing, a first target display image is rotated into a second horizontal drawing, and the second horizontal drawing is recorded.

In some scenarios, in response to a video recording operation by a user, the video recording application may send a video recording request to the executing body.

The foregoing may be referred to as a manner of rotating the first object display image into the second horizontal drawing, and will not be described herein.

If the first target display image displayed by the vertical screen is the first vertical image, the horizontal image is directly recorded, which may cause distortion of the recorded video frame. Therefore, the first target display image is rotated into the second transverse diagram, and then the second transverse diagram is recorded, so that the recorded image is ensured not to be distorted. Thus, when the first target display image displayed on the vertical screen is the first vertical image, even if the video recording request indicates that the recorded video frame is the video of the horizontal image, the video frame which is not distorted can be recorded.

And a second step of rotating the second horizontal drawing into a first vertical drawing and storing the first vertical drawing as a video frame in the video.

The foregoing may be referred to as a manner of rotating the second horizontal drawing to the first vertical drawing, and will not be described herein.

It is not difficult to find that the recorded second horizontal drawing does not coincide with the first target display image (i.e., the first vertical drawing) displayed in the vertical screen. Therefore, the recorded second transverse diagram is rotated into the first vertical diagram, and then the first vertical diagram is stored into the video as the video frame, so that the video frame contained in the video can be ensured to be consistent with the first vertical diagram displayed to a user through the vertical screen.

In some embodiments, the executing body may further execute the following steps after displaying the first target display image in the vertical screen.

In the first step, in response to a switching operation of the image display mode, the initial horizontal drawing is converted into a second target display image suitable for display on the vertical screen based on the switched image display mode.

In some scenarios, the toggle operation may be a triggering operation of a toggle control presented in the portrait screen described above.

Note that, the manner of converting the target display image into the second target display image is similar to the manner of converting the target display image into the first target display image, and will not be described here again.

And a second step of switching to display a second target display image in the vertical screen.

It can be seen that the user can flexibly switch the mode of displaying the target display image by the vertical screen device. Therefore, the flexibility of viewing the target display image by the user can be improved.
