Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

Example 1

FIG. 1 is a flow chart of a photographing method based on image adjustment provided in Embodiment 1 of the present invention. This embodiment can be applied to a situation where an intelligent terminal is used to take a photograph. The method can be executed by an intelligent terminal such as a smartphone and a tablet computer. It includes the following steps:

Step 110: Acquire the target image area from the target frame picture.

Wherein, the target image area is an image area corresponding to the target object in the target frame picture.

The frames captured by the camera are displayed on the display screen in real time. The target frame picture can be the current frame picture displayed on the display screen. Since the frame images acquired by the camera may change at any time, the target frame images may also be the frame images corresponding to the moment selected by the photographer at a certain moment. For example, if the user adjusts a certain target image area of the frame displayed on the display screen at 12:00, it is determined that the user chooses to determine the frame displayed on the display screen at 12:00 as the target frame at 12:00 .

First, the contour lines of each object are found from the target frame picture through image analysis, and the closed area formed by the contour lines forms the first image area. During image analysis, the boundary of different color blocks can be identified by the boundary tracking algorithm, and then the outline of the object can be obtained. Further, after the first image area is determined, the obtained first image area is screened according to the category of the target object. The categories of target objects such as people, animals, furniture, cars, airplanes, etc. Secondly, the user selects one or more first image regions as target image regions in the obtained first image regions.

Step 120: Adjust the target image area according to the user's instruction.

Adjustments include movement, rotation. If the target image area is a human body image area, the adjustment also includes adjustment of the posture of the human body. When there are multiple target image areas, the multiple target image areas can be adjusted according to the same displacement vector input by the user, and the user can also adjust the individual target image areas by dragging and dropping individually.

Exemplarily, after the user selects N (N is a positive integer greater than 1) target image areas, the N target image areas are adjusted uniformly by default. For example, the user keeps his finger on a target image area a displayed on the touch screen, and then drags the target image area a from the current position a-1 to another position a-2. Then, the displacement vector is determined according to the coordinates a-1 and a-2, and the remaining N-1 target image areas in the N target image areas are moved according to the displacement vector. The user can cancel the unified adjustment of each target image area by clicking buttons such as "ungroup", and then the user can adjust a single target image area.

Step 130: If the actual position of the target object matches the adjustment result, take a photo.

If there are multiple target image areas, when there are corresponding target objects in all the adjusted target image areas, take a picture.

In this embodiment, the target image area in the target frame picture can be adjusted according to the user's instruction, and the photo is taken when the actual position of the target object matches the adjustment result. In the prior art, the entity of the target object needs to be moved to determine the photographing effect after the movement, and the photographing efficiency is low. This embodiment can realize the virtual adjustment of the target object in the target frame by adjusting the target image area, thereby eliminating the need to move the target object entity, saving time and effort, and achieving the effects of improving user experience and saving adjustment costs. At the same time, the target object is virtually adjusted in the target frame picture, so that the photographer can quickly obtain the adjustment effect and improve the photographing efficiency.

Embodiment 2

FIG. 2 is a flowchart of a photographing method based on image adjustment provided by Embodiment 2 of the present invention. As a further description of Embodiment 1, step 110, acquiring a target image area from a target frame picture, can be implemented in the following manner:

Step 110a, acquiring a human body image area from the target frame picture.

The human body image area is an image area corresponding to the human body contour in the target frame picture. Due to the special adjustment of the human body contour, the feature vector of the human body contour can be obtained through machine learning and other methods, and the human image area can be found from the image areas of various objects according to the feature vector of the human body contour.

Exemplarily, as shown in the left side of FIG. 3 , in step 120a, three human body image regions are acquired, and the three human body image regions correspond to one taller and two lower tall people respectively, and the two figures are from left to right. A taller person and a taller person. The user finds that the photos taken by such a position are not good-looking, so the user can move the three human body image areas by dragging and other methods to obtain the position that the user thinks is better for taking pictures, as shown on the right side of Figure 3. The taller characters are in the middle, and the lower reviewers are on either side of the taller characters.

In practical use, a smartphone or tablet is usually used to take pictures of people. When taking pictures of people, especially when taking pictures of people of multiple people, it is necessary to reasonably arrange the positions and shapes of the multiple people, so as to achieve better photographing effects. In this embodiment, by acquiring the person image area in the target frame picture, the photographer can adjust the person image area in the target frame picture, realize the virtual adjustment of the person's position, and improve the photographing efficiency of the person photographing.

Since the effect of different photographing poses (also known as poses) of the person taking pictures is quite different, the user needs to move the virtual image of the person being photographed (that is, the person image area) when taking pictures. The requirements for designing the virtual photo pose of the person being photographed. Therefore, only moving the human body image area cannot meet the above-mentioned requirements of the user. Correspondingly, further, in step 120, the target image area is adjusted according to the user's instruction, including:

Step 120a: Adjust the posture corresponding to the human body image area according to the posture adjustment instruction input by the user.

First, configure the human body image area with a human body model matching its area, which is a model with adjustable nodes. Then, by changing the position of the adjustable nodes, the configured human body model is fitted to the human body image area. Finally, the displacement command input by the user for the adjustable node is received. The adjustable nodes include neck nodes, left and right elbow joint nodes, left and right wrist joint nodes, left and right knee joint nodes, and left and right swap joint nodes. Further, the adjustable nodes also include nodes of each knuckle of the finger.

Further, if the human body image area does not include all areas of the human body model, such as only the upper body, the human body model corresponding to the human body image area is configured, such as only the own model is configured.

Exemplarily, as shown in FIG. 4 , a schematic diagram of a human body model before adjustment is shown on the left side of FIG. 4 , and the user can drag the adjustable nodes to realize the adjustment. In Figure 4, circles represent adjustable nodes. A schematic diagram of the adjusted human model is given on the right side of Figure 4. Further, the user can first drag the human body image area to determine the virtual position of the photographed object, and then push and adjust the adjustable nodes on the virtual human body model of the photographed object to realize the design of the photographed object. modeling.

In this embodiment, the virtual position and virtual posture of the person to be photographed can be designed (also referred to as adjustment) when taking a picture of a person, and then the picture can be taken according to the virtual position and virtual posture obtained by the design, which can avoid letting the real person of the person to be photographed arrive. On-site adjustments are made to greatly improve the efficiency of the layout design of photos and improve the user experience.

Embodiment 3

FIG. 5 is a flowchart of a photographing method based on image adjustment provided by Embodiment 3 of the present invention. As a further description of the above embodiment, step 120, adjusting the target image area according to a user instruction, can be performed in the following manner Implementation:

Step 120b, move the position of the target image area according to the displacement instruction input by the user. or,

Step 120c: Rotate the target image area according to the rotation instruction input by the user.

When shooting still life, such as shooting multiple objects placed on the desktop, after the smartphone or tablet has obtained the image area of each still life, the user can drag the target image area or rotate the target image area to achieve a better composition layout . When rotating, you can rotate with the preset coordinate point as the rotation center point. The preset coordinate point can be any coordinate point in the target area, preferably the geometric center point of the target area.

Exemplarily, as shown on the left side of Figure 6, there are two identical isosceles right triangle moulds, a square mould and a semicircle mould above the table top, wherein the side length of the true square is the same as the waist of the isosceles right triangle and The radius of the semi-circle is the same length, and the above four molds are scattered on the table. The images taken at this time are scattered and poorly composed. The user can obtain the placement mode shown on the right side of FIG. 6 by rotating and dragging the virtual image area of the above-mentioned molds, and rearrange the four molds according to the placement mode on the right side of FIG. 6 to achieve a better photographing effect.

This embodiment can adjust the target image area by moving or rotating, and is suitable for still life shooting, especially in top view or bottom view shooting, providing users with more abundant adjustment scenes and improving user experience.

Optionally, if the first image area includes both a human image area and a non-human image area (also known as a still image area), a first image area of the same type is recommended for the user according to the type of the target image area first selected by the user. For example, if the user selects a human body image region, other human body image regions are recommended for the user. The user can reject the recommendation and select the still life image area; he can also select the target area from the recommended human image areas.

This embodiment enables the user to select a target image area in the first image area, so that the user can actively select different types of image areas as the target image area, thereby improving usability and further improving user experience.
