Embodiment 1

[0036] image 3 It is a flow chart of an embodiment of the image scaling processing method provided by the present invention. The execution body of the method can be the above-mentioned business system, or various terminal devices with image processing functions, or can be integrated on these terminal devices. device or chip. like image 3 As shown, the image scaling processing method includes the following steps:

[0037] S301. Determine a zoom parameter to be adjusted for the picture according to the property of the picture.

[0038] In the embodiment of the present invention, according to different application scenarios, different scaling parameters to be adjusted may be determined according to the attributes of the picture. For example, in an application scenario where the size of the photo is adjusted according to the area of ​​the portrait in the portrait photo, the area of ​​the portrait is the scaling parameter of the picture to be adjusted. In this application sce...

Embodiment 2

[0046] Figure 4 It is a flow chart of another embodiment of the image scaling processing method provided by the present invention. like Figure 4 shown in the above image 3 On the basis of the illustrated embodiment, the image scaling processing method provided in this embodiment may further include the following steps:

[0047] S401. For each of the multiple pictures to be processed, according to the attributes of each picture, obtain a scaling parameter to be adjusted for each picture.

[0048] In the embodiment of the present invention, when there are multiple pictures to be processed, firstly, according to the attributes of each picture, the scaling parameters to be adjusted of each picture are acquired respectively. Specifically, the attributes of the picture may include but not limited to: pixel values ​​and / or transparency values ​​of each pixel in the picture.

[0049] S402. Among the multiple pictures to be processed, select a scaling parameter to be adjusted of...

[0059] Figure 5 It is a flow chart of another embodiment of the image scaling processing method provided by the present invention. like Figure 5 shown in the above image 3 and Figure 4 On the basis of the illustrated embodiment, the image scaling processing method provided in this embodiment may further include the following steps:

[0060] S501. According to the pixel value and transparency value of each pixel in the picture, determine the area of ​​the picture except for the white area and the fully transparent color area as the zoom parameter to be adjusted for the picture.

[0061] In the embodiment of the present invention, it can be applied to an application scenario where the image size is adjusted according to the visual area. First, for each picture to be processed, according to the pixel value and transparency value of each pixel point in the picture, the area of ​​the area (that is, the visual area) outside the white area and the fully transparent color area...

Abstract

The embodiment of the invention provides a picture scaling processing method and device and electronic equipment. The method comprises the following steps: determining a scaling parameter to be adjusted of a picture according to the attribute of the picture; determining a reference value used for scaling the picture; and zooming the picture according to the reference value, so as to enable a to-be-adjusted zooming parameter of the picture to conform to the reference value. According to the embodiment of the invention, the to-be-adjusted scaling parameter of the picture is accurately determinedthrough the attribute of the picture, and scaling adjustment can be automatically carried out on the picture according to a specific requirement (reference value), so that the defects caused by manual picture adjustment are avoided, the adjustment precision is improved, the labor cost is reduced, and the working efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for image zooming and processing, and electronic equipment. Background technique [0002] In the prior art, there are common practical applications of adjusting the size of an entire picture according to a specific area of ​​the picture for a specific purpose (eg, visual effect). [0003] For example, when displaying corporate logos on the logo wall, different corporate logos have different size ratios. Ideally, all logos look to have the same area (visually, not real area), which is not only beautiful, but also makes the brand on the wall more attractive. feel fair. [0004] In the process of implementing the present invention, the inventor found at least the following problems in the prior art: in the prior art, the adjustment of the image size according to the area of ​​a specific area is usually done manually. That is, observe with human...
