Problems solved by technology

However, for most users, it is more difficult to capture a moment in the process of movement. It is difficult for ordinary users to grasp the best timing for capturing, either the capture is too early or the capture is too late, and it is difficult to grasp the timing
In the prior art, it is more difficult to photograph moving objects

[0100] Based on the first embodiment, in this embodiment, because "Xiaomei" is locked after the initial focus, after the image of "Xiaomei" is captured, the foreground image of the captured image can be extracted, that is, "Xiaomei" can be extracted rough outline of the human body. Then you can call the relevant algorithm in OpenCV (Open Source Computer Vision Library, which is an open source cross-platform vision library that provides a variety of general algorithms for image processing and computer vision) to remove the holes and scattered white in the extracted human outline. point. Finally, extract the features of the human body contour, first select the reference point, and determine the leftmost point A, the rightmost point B, the highest point C, and the lowest point D in the human body contour. According to A, B, C, D four points, calculate the center point M of human body outline, present embodiment uses center point M as the calculation point of motion vector, rathe...

Abstract

The invention discloses a photographing device, the photographing device includes: an acquisition module, used to acquire a first motion vector of a target object within a preset time period, wherein the preset time period is two consecutive frames captured by a mobile terminal Interval time between images; a judging module, configured to judge whether the target object is still based on the acquired first motion vector and a preset threshold; a photographing module, configured to photograph the target object when the target object is stationary. The invention also discloses a photographing method. The invention can reduce the difficulty of photographing moving objects.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a photographing device and method. Background technique [0002] With the popularity of smart terminals and the continuous advancement of smart terminal technology, mobile terminals, mainly mobile phones, are more and more widely used in the field of photography. However, for most users, it is more difficult to capture a moment in the motion process, and it is difficult for ordinary users to grasp the best capture time, either the capture is too early or the capture is too late, and it is difficult to grasp the timing. In the prior art, it is quite difficult to photograph moving objects. Contents of the invention [0003] The main purpose of the present invention is to provide a photographing device and method, aiming at reducing the difficulty of photographing moving objects. [0004] To achieve the above object, the present invention provides a photogr...
