Problems solved by technology

[0003] Taking pictures, snapshots, or selfies with a mobile terminal is a scene that users repeat every day. However, when users use the terminal to take pictures, they usually cause strong or weak shaking due to various reasons.
[0004] In the prior art, the method of multi-frame optimization is usually used for anti-shake, but the conventional multi-frame algorithm does not consider the individual situation of the photographer. The usual method is to start from triggering the shutter, take multiple frames, and then select clear images from these frames. frame, but this method does not consider the state before the photo is taken, and it is also a rigid capture frame after the photo is taken, and the effect of anti-shake optimization is limited

Embodiment 1

[0067] See figure 1 , figure 1 It is a flow chart of a preferred multi-frame method for anti-shake in hand-held photography disclosed in the first embodiment. figure 1 The shown multi-frame optimization method for handheld photo stabilization is applied to smart mobile terminals equipped with cameras, including but not limited to mobile phones, notebook computers, tablet computers, palm Internet devices, and multimedia devices , streaming media devices, mobile internet devices (MID, mobileinternetdevice), wearable devices or other types of terminal devices.

[0068] as attached figure 1 As shown, a multi-frame optimization method for hand-held photo stabilization specifically includes the following steps:

[0069] Step S101 , receiving a camera preview command, collecting buffered image frames of the scene through the camera and storing them in the image buffer queue.

[0070] In a specific application, when the user wants to take a photo through the mobile terminal, he ca...

Embodiment 2

[0111] For the purpose of providing a way to prevent blurred photos caused by shaking when the mobile terminal takes pictures, and at the same time make the anti-shake method intelligent for learning, this embodiment proposes a multi-frame optimization device for hand-held photo stabilization. Pre-prediction and trend judgment after taking photos to judge the vibration of the current terminal equipment, and then determine the optimal scheme of the image cache frame to ensure that the cached image frame with the best quality is selected as the photo image, and finally the output of the photo image in a certain format. A preferred multi-frame device for handheld photo stabilization disclosed in Embodiment 2, its structural block diagram is as follows Figure 5 As shown, the device includes: a photographing storage module 201, a photographing instruction module 202, a first judgment module 203, a second judgment module 204, a policy determination module 205, and a photographing ou...

Abstract

The invention discloses a multi-frame optimization method, device and mobile terminal for hand-held photo stabilization. The method includes the following steps: receiving a photo preview instruction, collecting and storing buffered image frames of the scene through a camera and storing them in an image buffer queue; Receive the photographing instruction; take the triggering time of the photographing instruction as the origin, judge whether the vibration trend from the beginning to the end in the previous first threshold time period t1 is rising or falling and the vibration trend from the beginning to the end in the second threshold time period t2 afterwards Whether it is rising or falling; look up the vibration trend mapping relationship table to obtain the preferred photography strategy; determine the photographed image according to the photographed preferred strategy, and output the photographed image. This scheme enables the multi-frame optimization method to have a dynamic cognitive learning function, has a strong ability to adapt to the photographing environment, significantly improves the success rate of photographing, avoids blurred photos caused by camera shake, and brings better benefits to mobile terminal users. operating experience.

Description

technical field [0001] The present invention relates to the field of communication technology of mobile terminals, in particular to a multi-frame optimization method, device and mobile terminal for anti-shake in hand-held photography. Background technique [0002] With the development of terminal technology and digital camera technology, the camera has become the standard configuration of most terminal equipment, providing users with the camera function, bringing great fun and convenience to people's life and work, and the camera pixels are getting higher and higher, Designed to allow users to take better quality photos. [0003] Taking pictures, snapshots, or selfies with a mobile terminal is a scene that users repeat every day. However, when users use the terminal to take pictures, there are usually strong or weak shakes due to various reasons. [0004] In the prior art, the method of multi-frame optimization is usually used for anti-shake, but the conventional multi-fram...
