Embodiment 1

[0024] see figure 1 , is a flow chart of an image processing method provided in Embodiment 1 of the present invention. The method in the embodiment of the present invention can be executed by a picture processing device implemented by hardware and / or software, and the realization device is typically configured in a camera or a smart phone that can provide picture shooting and picture processing services, or can be configured in a Cameras that provide picture taking and picture processing services or software applications related to taking pictures in smartphones.

[0025] The method includes: operation 110 - operation 130 .

[0026] In operation 110, during the shooting process, at least three photographed pictures are acquired.

[0027] Specifically, this operation may be that firstly, during the shooting process, the shutter is continuously pressed for several seconds, several pictures are continuously taken every fixed time (for example, 1 second), and then at least three...

Embodiment 2

[0057] On the basis of the above-mentioned embodiments, this embodiment provides a preset picture dynamic background filtering strategy to merge the at least three pictures to obtain a preferred solution for the operation of merging pictures. see figure 2 , is a flow chart of a method for merging processing in an image processing method provided in Embodiment 2 of the present invention. The method merges the at least three pictures based on a preset picture dynamic background filtering strategy to obtain a combined picture, specifically including: operation 210 - operation 220 .

[0058] In operation 210, count the pixel values ​​corresponding to the same pixel in the at least three pictures.

[0059] In this operation, you can traverse each pixel in each of the obtained pictures, and count the pixel value corresponding to each pixel in the picture; in each obtained picture, each pixel corresponds to After the pixel value of each picture, the pixel value corresponding to th...

Embodiment 3

[0066] On the basis of the first embodiment above, this embodiment provides a preset dynamic background filtering strategy for pictures to merge the at least three pictures to obtain another preferred solution for the operation of merging pictures.

[0067] see image 3 , is a flow chart of a method for merging pictures in a picture processing method provided in Embodiment 3 of the present invention. The method merges the at least three pictures based on a preset picture dynamic background filtering strategy to obtain a combined picture, specifically including: operation 310 - operation 340 .

[0068] In operation 310, count the pixel values ​​corresponding to the same pixel in the at least three pictures. This operation is similar to the above-mentioned operation 210 and will not be repeated here.

[0069] In operation 320, according to the statistical pixel values, the dynamic background area of ​​each picture in the at least three pictures is respectively determined, wher...

Abstract

The embodiment of the invention provides a picture processing method and device. The picture processing method comprises the steps that in a shooting process, at least three pictures obtained through shooting are obtained; the at least three pictures are merged based on a preset picture dynamic background filtering strategy, so that a merged picture is obtained, wherein the dynamic background filtering strategy is used for filtering out dynamic backgrounds in the at least three pictures; the merged picture is displayed. Due to the fact that a shot target is kept static in the shooting process, the shot target is located at the same position in the obtained at least three pictures; due to the fact that the dynamic backgrounds move dynamically relative to the shot target in the shooting process, the dynamic backgrounds appear at different positions in the obtained at least three pictures; in this way, the at least three pictures are merged based on the filtering strategy, then only the part kept static in the shooting process is shown in the obtained merged picture, the dynamic backgrounds are filtered out, a user can obtain a picture with a clean background, and photographing experience is improved for the user.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to an image processing method and device. Background technique [0002] Taking pictures is an indispensable activity in people's life, especially in tourist attractions, taking pictures is even more indispensable. Especially in places with the best views, the more people take pictures. [0003] But the better the view, the more people will visit, especially on holidays. If you want to take pictures in a place with a better view, you must wait until there is no one to take a photo with a clean background, otherwise there will always be something wrong in the photos you take. Desired person or thing (i.e. dynamic background). [0004] However, there is currently no technology for removing undesired people or objects in the background when taking pictures, so that the camera equipment cannot take pictures with a clean background in places where the...
