Example Embodiment

[0046] The basic idea of ​​the present invention is to obtain the movement direction and acceleration of the camera during the shooting process, and calculate the offset of the camera on the shooting plane according to the obtained acceleration; A filter matrix for filtering the captured image; use the selected filter matrix to filter the captured image and save the filtered image.

[0047] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to embodiments and drawings.

[0048] figure 2 Shows the flow of the filter matrix construction method, such as figure 2 As shown, the method includes the following steps:

[0049] Step S201, determining the direction and order of the filter matrix to be constructed;

[0050] In this step, the order of the filter matrix is ​​generally an odd number greater than or equal to 3, and the direction of the filter matrix is ...

Abstract

The invention provides an anti-shaking method and an anti-shaking device for a mobile terminal camera. The method comprises the following steps of: acquiring motion direction and acceleration of the camera during shooting, and calculating the offset of the camera in a shooting plane according to the acceleration; selecting a filter matrix for filtering images shot by the camera according to the motion direction and the offset; and filtering the images by using the filter matrix, and storing the filtered images. By constructing the filter matrix and enhancing the images in the normal direction of the image matrix with pertinence, the anti-shaking method and the anti-shaking device for the mobile terminal camera can effectively remove the noise of the images due to shaking of the camera, well optimize the anti-shaking function of the mobile terminal camera, and are easier to implement.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an anti-shake method and device for a camera of a mobile terminal. Background technique [0002] The exposure time of the mobile terminal camera is inversely proportional to the speed of the shooting object, and in the shooting process, light collection and equalization take time, and the exposure time cannot be reduced to a very short time. Therefore, the exposure time is affected by various external factors. The mobile terminal camera usually shakes, and the shaking will have a serious impact on the shooting effect, but in a small time slice (such as the exposure time of the camera), it can be considered that the movement direction of the mobile terminal camera is a single . Such as figure 1 As shown, during the exposure time of the camera, camera shaking will cause: the superposition of multiple images in one direction, such as figure 1 As shown, it is the image capt...
