Problems solved by technology

In order to solve this problem, the method of pixel segmentation of digital images is now commonly used, such as segmenting the image from top to bottom or from left to right, and transmitting the segmented image data one by one, and the receiving end decodes while receiving, and the displayed effect The image is gradually displayed from top to bottom or from left to right. Although this technology is slightly better than the traditional method, the user who receives the image cannot see the content of the image immediately, and feels that the image is forcibly divided, which affects the user experience.

Embodiment 1

[0037] figure 1 It is the flowchart of this embodiment. It includes the following steps:

[0038] S101. Divide the image data into N sets, the union of the sets is equal to the entire image data, and the image data density of the union of at least two sets is greater than the image data density of any one of the two sets;

[0039] The image data density here is defined as follows: if the pixels corresponding to this set form a single connected domain, the data density is equal to the amount of data contained in the set divided by the number of pixels, if it is a complex connected domain or not, then Data density can be defined as the amount of data contained in the collection divided by the number of pixels in the entire image. The so-called connected domain means that any two points in the area can be connected by a curve in the area. If any closed curve in the connected domain can be continuously shrunk to a point in the area without crossing the boundary of the area, the ...

Embodiment 2

[0044] In this embodiment, P Mod Q represents an operation of dividing an integer P by an integer Q to obtain a remainder.

[0045] Such as figure 2 As shown, in this embodiment, S101 in Embodiment 1 specifically includes:

[0046] S2101, performing an operation of dividing the row identifier or column identifier of the pixel in the image by N to obtain a remainder, and the image data corresponding to the pixels whose operation results are 0, 1, ..., N-1 are respectively the described One of N sets.

[0047] Here, the row ID and the column ID refer to the sequence numbers of the row and column respectively. The display effect of this embodiment at the receiving end is that rows or columns at a certain distance are displayed sequentially, like the effect of closing a shutter.

[0048] This embodiment can also be modified as follows, such as Figure 2a As shown, the aforementioned S2101 is specifically:

[0049] S21011, performing an operation of dividing the row identifie...

Embodiment 3

[0053] In this embodiment, image data is divided into sets according to color channels. Such as image 3 As shown, in this embodiment, S101 in Embodiment 1 is specifically:

[0054] S3101. Get the data of each color channel in the image into N sets respectively, where N is equal to the number of color channels.

[0055] Here, the color channels store the values ​​of each color component in the image respectively. Taking the common RGB image as an example, the image includes three color channels of red (R), green (G), and blue (B), which respectively store the red color of each pixel. , green and blue values. Classify the data of each color channel into N sets (N is equal to the number of color channels), and then send the image data included in the N sets respectively. The display effect at the receiving end is to gradually display an image from phantom color to true color. For example, when transmitting an RGB image, the data of the red, green, and blue channels are transm...

Abstract

The invention provides a method for transmitting digital images, which comprises the following steps: dividing image data into N sets, wherein the union of the sets is equal to the whole image data, and the image data density of the union of at least two sets is larger than that of any one set of the two sets; and transmitting the data contained in the N sets respectively. The invention also provides a digital image transmitting device.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a digital image sending method and device. Background technique [0002] Digital images are used more and more widely in people's lives today, and the transmission of digital images on the network is also more and more common. With the advancement of technology, digital images now have more and more pixels, and the storage volume occupied is correspondingly larger and larger. This makes the transmission of digital images in the network limited by the network bandwidth, and sometimes the transmission time will be longer. long. Under the traditional transmission method, it is only after receiving all the data of an image that it is decoded and displayed, and the user has to wait for a long time to see the image. In order to solve this problem, the method of pixel segmentation of digital images is now commonly used, such as segmenting the image from top to bottom or from left to ri...
