Embodiments of the invention

In order to make the object, the features and the advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

Referring to FIG. 1, an embodiment of an image display method in an embodiment of the present application may include:

Step S101: Acquire a target image to be displayed.

The target image may be a photo or photography, a painting, or the like shared on the Internet.

Step S102, dividing the target image into two or more sub-images.

The sub-image is a partial image of the target image, and each sub-image is a part of the target image, and each sub-image may constitute a complete target image.

Establishing a Cartesian coordinate system, and the area of the target image in the coordinate system may be represented as Area (X _left , X _right , Y _top , Y _bottom ), wherein Xleft is the leftmost horizontal coordinate of the target image Xright is the abscissa of the rightmost side of the target image, Ytop is the ordinate of the top of the target image, and Ybottom is the ordinate of the bottom of the target image.

The manner in which the target image is divided can be various, and the following divisions are only examples:

Image division mode 1: The target image is vertically divided into N sub-images, wherein N≥2, then N sub-images can be respectively represented as:

SubArea _n (X _{left_n} , X _{right_n} , Y _top , Y _bottom ).

Wherein X _{left_n} = X _left + (n-1) * Δx, X _{right_n} = X _left + n * Δx, Δx = (X _right - X _left ) / N, 1 ≤ n ≤ N.

Image division mode 2: The target image is equally divided into N sub-images, wherein, if N≥2, the N sub-images can be respectively represented as:

SubArea _n (X _left , X _right , Y _{top_n} , Y _{bottom_n} ).

Wherein, Y _{bottom_n} = Y _bottom + (n - 1) * Δy, Y _{top_n} = Y _top + n * Δy, Δy = (Y _{top -} Y _bottom ) / N, 1 ≤ n ≤ N.

Image division mode 3: divide the target image into S*T=N sub-images, where N≥2, S is the number of points equally divided in the vertical direction, and T is the number equally divided in the horizontal direction, then N sub-images can be expressed as:

SubArea _st (X _{left_s} , X _{right_s} , Y _{top_t} , Y _{bottom_t} ).

Where X _{left_s} =X _left +(s-1)*Δx, X _{right_s} =X _left +s*Δx, Δx=(X _right -X _left )/S,Y _{bottom_t} =Y _bottom +(t-1)* Δy, Y _{top_t} = Y _top + t * Δy, Δy = (Y _{top -} Y _bottom ) / T, 1 ≤ s ≤ S, 1 ≤ t ≤ T.

It should be particularly noted that the above various division methods are only examples, and other division manners may be derived on the basis of this.

Step S103: Generate an image sequence including two or more transformed images according to the target image.

The transformed image is an image obtained by performing hidden processing on one or more sub-images in the target image. In a continuous two-frame transformed image, any one of the sub-images is not hidden in at least one transformed image. .

As shown in FIG. 2, step S103 may specifically include the following process:

Step S1031: Determine a first number of sub-images to be hidden in each transformed image.

The first number may be set according to an actual situation. For example, the first number may be set to be positively correlated with the total number of sub-images into which the target image is divided. The more the total number of sub-images, the more the first number of sub-images to be hidden.

Step S1032: Initialize a preset number of frame counts.

The frame count value can be represented by f, and the initialization process can be expressed as: f=0.

Step S1033: Select a first number of sub-images from the target image.

The specific selection methods can be various, and the following selection methods are only examples:

Selecting a method 1: first, obtaining the frame number count value, and then determining, according to the frame number count value and a preset first function relationship, a sequence number of the sub-image to be hidden, wherein the first function relationship is the frame The function relationship between the number count value and the sequence number of the sub-image to be hidden is processed, and finally, the sub-image corresponding to the determined serial number is selected.

For example, the first functional relationship can be:

Where N is the total number of sub-images into which the target image is divided, N ₁ is the first number, Mod is a remainder function, Floor is a downward value function, and SN _n is determined to be hidden. The serial number of the processed sub-image.

When N=100, N ₁ =10, and f=0, it can be obtained that: SN ₁ =1, SN ₂ =11, SN ₃ =21, ..., SN ₁₀ =91, that is, the first frame selection number is 1. Sub-images of 11, 21, ..., 91, when f = 1, can be obtained: SN ₁ = 2, SN ₂ = 12, SN ₃ = 22, ..., SN ₁₀ = 92, that is, the second frame is selected Sub-images with numbers 2, 12, 22, ..., 92, when f = 2, can be obtained: SN ₁ = 3, SN ₂ = 13, SN ₃ = 23, ..., SN ₁₀ = 93, that is, the first A sub-image with numbers 3, 13, 23, ..., 93 is selected in one frame, and so on.

Selecting method 2: obtaining the frame number count value, if the frame number count value is 0, randomly selecting the first number of sub-images from the target image according to a preset selection probability of each sub-image; If the frame number count value is not 0, the first number of sub-images are randomly selected from the candidate sub-image set according to the selection probability of each sub-image, and the candidate sub-image set is the selected sub-image set at the target A complement in the image, the selected set of sub-images being a set of sub-images selected during the generation of the transformed image of the previous frame.

The preset process of the selection probability of each sub-image may include:

First, the information entropy of each sub-image in the target image is separately calculated, and the specific calculation formula is:

Where H _n is the information entropy of the nth sub-image, and p _ni is the proportion of the pixel points whose gradation value is i in the nth sub-image.

The information entropy is then summed to obtain a total information entropy of the target image. If the total information entropy of the target image is represented by H, then:

Finally, the ratio of the information entropy of any sub-image to the total information entropy is calculated, and the ratio is determined as the probability of selection of the sub-image. If the selection probability of the nth sub-image is represented by p' _n , then:

The selection probability calculated by the above method is proportional to the size of the information entropy. The larger the information entropy of a sub-image is, the larger the probability of being selected. Conversely, the smaller the information entropy of a sub-image is selected. The lower the probability, the most extreme case, when a sub-image has only one gray value, its information entropy is 0, then the probability of its selection is also zero.

Step S1034: Perform hidden processing on the selected sub-image to generate a frame-converted image.

Specifically, the selected sub-image may be set to pure white, that is, the gray value of each pixel thereof is set to 255. Do not process any other sub-images and keep their original state.

Step S1035: Add the generated transformed image into the image sequence.

The sequence of images is arranged in the order in which the transformed images are generated, that is, the transformed images that are formed by the former are arranged at a previous position, and the transformed images that are generated later are arranged at a later position.

Step S1036, adding the frame count value to one count unit.

That is, f=f+1.

Step S1037: Determine whether the frame number count value is smaller than a preset total number of frames of the image sequence.

If the frame count value is smaller than the preset total number of frames of the image sequence, returning to step S1033 and subsequent steps.

If the frame count value is equal to the preset total number of frames of the image sequence, step S1038 is performed.

Step S1038, saving the image sequence.

That is, after there are enough transformed image frames in the image sequence, a new transformed image is no longer generated, and the existing image sequence can be directly saved.

Step S104: cyclically display the image sequence in sequence according to a preset display interval.

The display interval is less than the visual persistence time of the human body. For example, the display interval may be set to 0.01 seconds, 0.02 seconds, 0.04 seconds, and the like.

The persistence of vision is a phenomenon in which the light produced by the retina remains in the light after the light stops, and its specific application is the filming and screening of the film. The reason is caused by the reaction speed of the optic nerve. It is the basis for the formation and dissemination of visual media such as animation and movies. Vision is actually imaged by the lens of the eye, the photoreceptor cells are sensitive, and the light signal is converted into a nerve current, which is transmitted back to the brain to cause human vision. Photoreceptor cells rely on some photoreceptors, and the formation of photoreceptors takes a certain amount of time, which forms the mechanism of visual pause.

When the image sequence is cyclically displayed in accordance with the display interval, each time the displayed image displays only partial information instead of displaying all the information, but the visual persistence characteristic of the human eye can combine the information into one complete The picture information shows a complete picture in the eyes of the human eye, and the machine device does not have such characteristics. Therefore, the screen display intercepted at any time by any screen capture means only the partial picture data displayed at that moment, thereby achieving Protect the complete picture to be displayed without being copied and stolen.

In summary, the embodiment of the present application first acquires a target image to be displayed, divides the target image into two or more sub-images, and then generates an image sequence including two or more transformed images according to the target image, and finally according to the image sequence. The preset display interval sequentially displays the sequence of images cyclically. Since the transformed image is an image obtained by performing hidden processing on one or more sub-images in the target image, the images displayed in any one frame are incomplete, and the unlawful user obtains through downloading, screen capture, photographing, and the like. All are incomplete images, which effectively guarantee the legitimate rights and interests of the author. Meanwhile, since in any two consecutive frames of the transformed image, any one of the sub-images is not subjected to the concealing process in at least one of the transformed images, and the display interval is smaller than the visual persistence time of the human body, the user feels subjectively during normal viewing. Still a complete image, that is, while protecting the legitimate rights and interests of the author, it can also bring a better viewing experience to the user.

It should be understood that the size of the sequence of the steps in the above embodiments does not mean that the order of execution is performed. The order of execution of each process should be determined by its function and internal logic, and should not be construed as limiting the implementation process of the embodiments of the present application.
