Embodiment Construction

[0027] The embodiment of the present invention provides an image scaling processing method, which can solve the problem that the source image cannot be scaled because the pixel parameters are too small. The embodiment of the present invention also provides a related image scaling processing device. The details will be described respectively below.

[0028] For the basic flow of the image scaling processing method in the embodiment of the present invention, please refer to figure 1 , mainly including steps:

[0029] 101. The image processing device acquires pixel parameters of the first source image;

[0030] When the first source image is to be scaled, the image processing device first obtains pixel parameters of the first source image, the pixel parameters including: the number of horizontal pixels and the number of vertical pixels.

[0031] 102. The image processing device determines the minimum pixel parameter;

[0032] In the current image scaling algorithm, due to the...

Abstract

The embodiment of the invention discloses an image scaling processing method, which is used for scaling an image. The method in this embodiment of the present invention includes: the image processing device acquires the pixel parameter of the first source image; the image processing device determines the minimum pixel parameter; Padding a source image to obtain a second source image whose pixel parameter is not less than a minimum pixel parameter; the image processing device scales the second source image to obtain a first target image. The embodiment of the present invention solves the problem that the first source image cannot be scaled because the pixel parameter is too small by filling the first source image smaller than the minimum pixel parameter with the second source image not smaller than the minimum pixel parameter, and obtaining The first target image conforms to the desired scaling. The present invention also provides an image scaling processing device capable of realizing the above method.

Description

technical field [0001] The present invention relates to the technical field of image scaling processing, in particular to an image scaling processing method and a related device. Background technique [0002] Image scaling technology is one of common technologies in image processing, through which a source image can be scaled according to a scaling ratio to obtain a target image, and the target image can be presented on different terminal devices. In some image scaling algorithms at this stage, the image input or output to the algorithm must meet a condition, that is, the pixel parameter of the image cannot be smaller than a preset pixel parameter, for example, it cannot be smaller than 4×4 pixels. If the pixel parameter of the image input or output to the algorithm is smaller than the preset pixel parameter, the image scaling algorithm cannot be applied, and the image scaling performed by the algorithm cannot be realized. However, in some image processing processes, the pi...
