Problems solved by technology

[0005] However, in the above-mentioned electronic anti-shake solution, when determining the position changes among the multiple images collected, if the current shooting environment of the camera is poor, the resolution of the collected images may be low, resulting in the The determined position changes between the images are not accurate enough, which makes it impossible to obtain a better anti-shake effect when performing electronic anti-shake processing according to the determined position changes

Embodiment 1

[0032] figure 2 Shown is a flow chart of the shooting anti-shake method provided in Embodiment 1 of the present invention, which specifically includes the following processing steps:

[0033] Step S201. After the first camera used for the current shooting is turned on, the first camera will collect images in real time and cache them. The shooting device to which the first camera belongs acquires the images captured by the first camera, specifically, it may periodically acquire the latest images currently captured, and the acquisition period may be determined according to the attributes, use experience and actual needs of the cameras.

[0034] Step S202 , judging whether the resolution of the image captured by the first camera is less than the set resolution threshold, if yes, proceed to step S203 , otherwise, proceed to step S207 .

[0035] Due to the influence of light in the shooting environment where the current shooting device is located, the clarity of the image capture...

Embodiment 2

[0065] Figure 5 Shown is a flow chart of the shooting anti-shake method provided in Embodiment 2 of the present invention, which specifically includes the following processing steps:

[0066] Step S501, after the first camera used for the current shooting is turned on, the first camera will collect images in real time and cache them. The shooting device to which the first camera belongs acquires the images captured by the first camera, specifically, it may periodically acquire the latest images currently captured, and the acquisition period may be determined according to the attributes, use experience and actual needs of the cameras.

[0067] Step S502 , when the first camera used for the current shooting is turned on, the second camera is turned on at the same time, and the second camera collects images in real time and caches them. The shooting device then acquires the image captured by the second camera, specifically, it may periodically acquire the latest image currently...

Embodiment 3

[0079] Based on the same inventive concept, according to the anti-shake method provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 3 of the present invention also provides an anti-shake device for shooting, which can be installed on In the shooting equipment of the two cameras, the schematic diagram of its structure is as follows Image 6 shown, including:

[0080] An acquisition unit 601, configured to acquire an image captured by a second camera whose lens direction is opposite to that of the first camera at the time when the first camera captures the image;

[0081] A parameter determining unit 602, configured to determine a first position change parameter required for electronic anti-shake processing according to the acquired image;

[0082] The processing unit 603 is configured to perform electronic anti-shake processing on the image captured by the first camera at the shooting moment based on the determined first position ch...

Abstract

The invention discloses an anti-shake method for shooting and an anti-shake device for shooting. The anti-shake method for shooting comprises the following steps: obtaining an image collected at the shooting moment of a first camera shot image by a second camera whose lens direction is opposite to the lens direction of the first camera; determining a first position change parameter required in the process of performing an electronic anti-shake treatment according to the obtained image; and performing the electronic anti-shake treatment on the image collected at the shooting moment by the first camera on the basis of the determined first position change parameter. By adopting the solution provided by the embodiment of the invention, under the condition that the shooting environment of the first camera is worse than that of the second camera, a better anti-shake effect can be obtained, so that the clearness degree of the shot image is improved.

Description

technical field [0001] The present invention relates to the technical field of image capture and processing, in particular to a method and device for image stabilization. Background technique [0002] In the existing shooting technology, when shooting with a shooting device, the photosensitive device will be used to detect light within the shooting time corresponding to one shooting, and all the images obtained by the light sensing during the shooting time will be superimposed into one image. However, since the user may shake the shooting device during the shooting process, there will be slight position changes between the photosensitized images at different times within a shooting time, including displacement changes and angle changes, so there will be changes in the position Multiple images are superimposed together to obtain blurred and ghosted images, which in turn leads to the problem of unclear captured images. [0003] In order to solve this technical problem, it is ...
