Abstract

The invention discloses a photographing method and device based on image adjustment, and a terminal. A target image region is obtained from a target frame picture; the target image region is an image region corresponding to a target object in the target frame picture; the target image region is adjusted according to a user instruction; and photographing is carried out if the practical position of the target object is matched with the adjusting result. According to the embodiment of the invention, the target image region in the target frame picture can be adjusted according to the user instruction; photographing is carried out if the practical position of the target object is matched with the adjusting result; the target object is virtually adjusted in the target frame picture by adjusting the target image region; therefore, the target object entity does not need to move; the time and the power can be saved; therefore, the user experience is improved; the adjustment cost is reduced; simultaneously, the target object is virtually adjusted in the target frame picture; a photographer can rapidly obtain an adjusting effect; and thus, the photographing efficiency is increased.

Description

technical field

[0001] Embodiments of the present invention relate to photographing technology, and in particular, to a photographing method, device, and terminal based on image adjustment. Background technique

[0002] As the camera functions on smart terminals such as smart phones become more and more mature, users use smart phones and other smart terminals to take pictures more and more frequently.

[0003] The smart terminal displays the frame picture acquired by the camera through the display screen, and the user clicks the photo button to store the currently acquired frame picture as a photo.

[0004] When photographing a movable object, it is usually necessary to shift the object in order to achieve a better photo layout. However, when adjusting the displacement of the object, the user needs to move the entity of the object before knowing the layout effect of the displaced object, which is time-consuming and laborious, and the photographing efficiency is low.

Examples

Embodiment 1

[0029] figure 1 The flow chart of the image-adjusting-based photographing method provided by Embodiment 1 of the present invention, this embodiment is applicable to the situation where a smart terminal is used for photographing, and this method can be executed by smart terminals such as smart phones and tablet computers, specifically including the following step:

[0030] Step 110, acquiring the target image area from the target frame picture.

[0031] Wherein, the target image area is an image area corresponding to the target object in the target frame picture.

[0032] Display the frames captured by the camera on the display screen in real time. The target frame picture may be the current frame picture displayed on the display screen. Since the frame picture acquired by the camera may change at any time, the target frame picture may also be the frame picture corresponding to the moment selected by the photographer at a certain moment. For example, if the user adjusts a c...

Embodiment 2

[0041] figure 2 The flow chart of the image adjustment-based photographing method provided by Embodiment 2 of the present invention, as a further description of Embodiment 1, step 110, obtaining the target image area from the target frame picture, can be implemented in the following manner:

[0042] Step 110a, acquiring the human body image area from the target frame picture.

[0043] Wherein, the human body image area is an image area corresponding to the human body outline 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 by means of machine learning, etc., and the human body image area can be found from the image areas of various objects according to the feature vector of the human body contour.

[0044] Exemplary, such as image 3 As shown on the left, in step 120a, three human body image regions are obtained. The three human body image regions correspond to a taller person ...

Embodiment 3

[0053] Figure 5 The flow chart of the 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 user instructions, can be implemented in the following manner:

[0054] Step 120b, move the position of the target image area according to the displacement command input by the user. or,

[0055] Step 120c, rotate the target image area according to the rotation instruction input by the user.

[0056] When shooting still life, such as shooting multiple objects placed on the table, after the smartphone or tablet computer obtains 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 performing rotation, the preset coordinate point can be used as the rotation center point for rotation. The preset coordinate point can be any coordinate point...
