Embodiment 1

[0124] The embodiment of the present invention provides a method for image adjustment, which can be used for image reduction, such as figure 1 As shown, the image reduction method includes:

[0125] 101. Acquire a target adjustment value and redundant information of an image.

[0126] Wherein, the target adjustment value refers to a target reduction value of the image to be displayed.

[0127] Wherein, the redundant information in this step refers to the black border or white border of the image and other unimportant information. The unimportant information refers to information that has no significant effect on image display and will not cause image distortion or distortion after being removed. These unimportant information may be embodied in the form of pixels, pixel strips, or pixel blocks.

[0128]102. Determine a first gap of the image to be displayed according to the redundant information.

[0129] Wherein, the first seam is non-salient information of the image to be...

Embodiment 2

[0156] The present invention provides a method for image adjustment, and this embodiment is a method for shrinking pictures, such as image 3 As shown, the method includes:

[0157] 201. Acquire a target adjustment value of an image to be displayed, where the target adjustment value is a target reduction value of the image to be displayed.

[0158] Wherein, the target adjustment value refers to a target reduction value of the image to be displayed, that is, a value that needs to be reduced on the basis of the original size of the image to be displayed for the current multimedia playback device. The target adjustment value may be an adjustment value that the image to be displayed needs to satisfy the size constraint of the image to be displayed on the current multimedia playback device; it may also be an adjustment value customized by the user for the image to be displayed.

[0159] 202. Perform calculation according to the image information of the image to be displayed to obt...

Embodiment 3

[0201] The present invention provides a method for image adjustment, and this embodiment is a method for image enlargement, such as Figure 6 As shown, the method includes:

[0202] 301. Acquire a target adjustment value of an image to be displayed, where the target adjustment value is a target magnification value of the image to be displayed.

[0203] Wherein, the target adjustment value refers to a target magnification value of the picture to be displayed, that is, a value that needs to be magnified on the basis of the original size of the picture to be displayed for the current multimedia playback device. The target adjustment value may be an adjustment value that the image to be displayed needs to satisfy the size constraint of the image to be displayed on the current multimedia playback device; it may also be an adjustment value customized by the user for the image to be displayed.

[0204] 302. Perform calculation according to the image information of the image to be di...

Abstract

The embodiment of the invention provides a method, a device and a system for image adjustment, which relate to the technical field of multimedia, broaden the zooming range of multimedia resources and can prevent the problem that multimedia resources are distorted or deformed when the zooming range is wide. The embodiment of the invention includes the following steps: the target adjustment value of an image to be displayed is obtained, the seam carving algorithm is utilized to obtain the redundant information, an intermediate image and the like of the image to be displayed, and the shift map algorithm is utilized to zoom out the image to be displayed; in the process of zooming in the image, the intermediate image needs to be zoomed in first after being obtained, and the shift map algorithm is then used for zooming out the zoomed-in image. The invention is mainly applied in the process of zooming multimedia resources.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular to an image adjustment method, device and system. Background technique [0002] At present, the multimedia playing devices used by people are increasingly diversified, which puts forward higher requirements for displaying and playing multimedia resources on the multimedia playing devices. Usually, people hope that a multimedia playback device can play multimedia resources suitable for the resolution of its display component. The existing technology provides a content-aware-based adaptation technology, which can scale the currently displayed multimedia resource according to the structure and semantic information of the multimedia resource, thereby realizing the size adjustment of the currently displayed multimedia resource. Constraints, and can better maintain the visual effect of the multimedia and the integrity of the content. [0003] In the process of realizing the ...
