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 multi-frame optimal method for handheld camera anti-shake disclosed in the first embodiment. figure 1 The illustrated multi-frame optimization method for handheld camera anti-shake is applied to smart mobile terminals equipped with cameras. The smart mobile terminals include, but are not limited to, mobile phones, notebook computers, tablet computers, handheld 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 handheld camera anti-shake specifically includes the following steps:

[0069] Step S101: Receive a photo preview instruction, collect a buffered image frame of the photographed scene through the camera and store it in an image buffer queue.

[0070] In specific applications, when a user wants to take a photo through a mobile ...

Embodiment 2

[0111] In order to provide an original intention of preventing the blurring of photos caused by jitter while making the anti-shake method with learning intelligence when taking pictures on the mobile terminal, this embodiment proposes a multi-frame optimal device for hand-held camera anti-shake. The previous prediction and the trend judgment after the photo are used to determine the current vibration of the terminal device, and then determine the optimal scheme of the image buffer frame, to ensure that the best quality buffer image frame is used as the photo image, and finally the output of the photo image in a certain format is The structure block diagram of a multi-frame preferred device for handheld camera anti-shake disclosed in the second embodiment is as follows: Figure 5 As shown, the device includes: a photographing storage module 201, a photographing instruction module 202, a first determining module 203, a second determining module 204, a strategy determining module 20...

Abstract

The invention discloses a multi-frame optimization method and device for handheld photographic shake prevention and a mobile terminal. The method comprises the following steps: receiving a photographic preview instruction, acquiring cached image frames of a photographed scene and storing the cached image frames into an image cache queue; receiving a photographic instruction; judging that the vibration trend from beginning to end rises or falls within a first threshold time period t1 and within a second threshold time period t2 by using the photographic instruction trigger time as an origin; searching a vibration trend mapping relation table to obtain a photographic optimization strategy; determining a photographed image according to the photographic optimization strategy and outputting the photographed image. By adopting the solution, the multi-frame optimization method has a dynamic cognitive learning function, has strong photographic environment adaptability, significantly improves the photographic success rate, avoids fuzzy photos caused by photographic shake, and brings better operation experience to the user of the mobile terminal.

Description

Technical field [0001] The present invention relates to the communication technology field of mobile terminals, and in particular to a multi-frame optimization method, device and mobile terminal for handheld camera anti-shake. Background technique [0002] With the development of terminal technology and digital camera technology, cameras have become the standard configuration of most terminal equipment, providing users with camera functions, bringing great fun and convenience to people’s lives and work, and the pixels of cameras are getting higher and higher. Designed to allow users to take better quality photos. [0003] Hand-held mobile terminals to take photos, captures, or self-portraits are scenes that users repeat every day, but when users use the terminal to take photos, they usually experience 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 algori...
