As can be seen from the above, when the scheme provided by this embodiment is applied to image display, at least two target images to be displayed are generated according to an original image to be displayed, and each target image to be displayed is sequentially displayed according to a preset image display interval. The target image to be displayed comprises the content of the first image area and the content of the second image area, and the content of the first image area is as follows: the content of the second image area is: the processed image content contained in the corresponding area in the original image, that is, only part of the content in the original image is reserved in the target image to be displayed.

In addition, the content of the image contained in the original image can be obtained due to the content superposition of the first image area in the target image to be displayed. Therefore, when the target images to be displayed are sequentially displayed according to the preset image display interval, the user can visually think that the original images are displayed currently, and the user can see the original images.
The following describes an image display method according to an embodiment of the present invention.
First, the execution subject of the embodiment of the present invention may be a terminal device, for example: mobile phones, tablet computers, and the like.
Then, the concept related to the embodiment of the present invention is explained.
1. The screen refreshing interval refers to an interval for refreshing the screen of the terminal equipment. The screen refresh interval is the minimum interval at which the images of the terminal device are switched. For example: when the screen refresh interval of the terminal device is 1/60 second, the minimum interval of image switching is 1/60 second.
2. The human eye visual reaction time length refers to the minimum reaction time of the human eye from image acquisition to image information processing, that is, the minimum time length for which the human eye can perceive image switching. The typical human visual response time is about 1/16 of a second. Based on the principle of persistence of vision, when the duration of image switching is shorter than the duration of human eye visual reaction, a person is hard to perceive that multiple images are being switched, and the current image is considered to be displayed; when the image switching duration is longer than the human eye visual reaction duration, a human can perceive that multiple images are being switched, and the current display is considered to be multiple images. Taking an animation film as an example, each frame of image of the animation film describes an action, and when the continuous image frames are played in sequence within a certain time period, the effect of moving the images can be achieved, so that a human eye can see a video, which is a typical application of the persistence of vision principle.
Referring to fig. 1, fig. 1 is a schematic flowchart of a first image display method according to an embodiment of the present invention, where the method includes S101 to S103.
S101: and acquiring an original image to be displayed.
When the original image to be displayed is acquired, a storage address of the original image to be displayed in a server may be acquired first, and then the storage address may be searched for from a server providing the image, so as to acquire the image. For example: the storage address may be a URL (Uniform Resource Locator) address.
Specifically, the storage address of the original image of the image to be displayed in the server may be determined according to a click operation or an input operation of the user on the operation interface, and the original image may be downloaded based on the determined storage address.
S102: and generating at least two target images to be displayed according to the original image.
The actual number of the target images to be displayed may be set by a worker based on experience. The method can also be determined according to the screen refreshing interval and the human eye visual reaction time length. Specific determination manners can be found in the following embodiments, and detailed descriptions thereof are omitted.
The target image to be displayed includes the content of a first image area and the content of a second image area, and the content of the first image area is as follows: the content of the second image area is: and processing the processed image content contained in the corresponding area in the original image.
The content of the first image area in each target image to be displayed is superposed to obtain the image content contained in the original image. Specifically, the contents of the first image area in each target image to be displayed may have overlapped image contents, or may have non-overlapped image contents.
Taking fig. 2a, fig. 2b, and fig. 2c as examples, fig. 2a is a schematic diagram of an original image provided in an embodiment of the present invention, fig. 2b is a schematic diagram of an image to be displayed as a target provided in an embodiment of the present invention, and fig. 2c is a schematic diagram of another image to be displayed as a target provided in an embodiment of the present invention.
The target images to be displayed in fig. 2b and 2c are: the target image to be displayed is generated from the original image of fig. 2 a. The area marked 1 in fig. 2b and 2c is the first image area and the area marked 2 is the second image area.
Based on the comparison between fig. 2b, fig. 2c and fig. 2a, the contents of the first image region in fig. 2b and fig. 2c are: the content of the second image area in fig. 2b and 2c is: and processing the processed image content contained in the corresponding area in the original image. And the superposition of the contents of the first image area in fig. 2b and fig. 2c may result in the image contents contained in the original image.
It is assumed that the key area of the image in fig. 2a is the area where each five sense organs in the cat face are located, such as the area where the eyes, the nose, and the mouth are located, and the non-key area of the image is the remaining area of the image except the key area, so that, in fig. 2b, the content of the first image area includes the image content included in the non-key area in the original image, and the content of the second image area includes the image content included in the key area in the original image.
When the target to-be-displayed image is obtained, the original image may be copied to obtain at least two copied images, a first image area and a second image area in each copied image are determined, and the content of the second image area in each copied image is processed, for example, the pixel value of the image content may be adjusted, so that each target to-be-displayed image may be obtained, and the content of the original image may be obtained by overlapping the content of the first image area in each target to-be-displayed image.
The method for specifically generating at least two target images to be displayed can be seen in the following embodiments, and details thereof are not described herein.
And S103, sequentially displaying the target images to be displayed according to a preset image display interval.
The image display interval can be determined according to the number of the target images to be displayed, the screen refreshing interval and the human eye visual reaction time length.
The target images to be displayed are sequentially displayed according to a preset image display interval, the image display interval is determined according to the number of the target images to be displayed, a screen refreshing interval and human eye visual reaction time, the human eye visual reaction time is the minimum reaction time of human eyes in the process of acquiring images and processing image information, and when the image display interval is smaller than the human eye visual reaction time, the process of displaying each target image to be displayed can be difficultly perceived by human eyes. And the content of the image contained in the original image can be obtained due to the content superposition of the first image area in the target image to be displayed. Therefore, when the target images to be displayed are sequentially displayed according to the preset image display interval, the user can visually think that the original images are displayed currently, and the user can see the original images.
Specifically, when the image display interval duration is determined, an image display interval range may be determined according to the number of target images to be displayed, a screen refresh interval, and a human eye visual reaction duration, and then one duration may be selected from the determined range as the image display interval.
When the image display interval range is determined, that is, the minimum value and the maximum value of the image display interval are calculated.
In calculating the minimum value of the image display interval, in one embodiment of the present invention, the screen refresh interval may be a minimum interval value of the image display interval, and thus, the minimum value of the image display interval is the screen refresh interval.
When the maximum value of the image display interval is calculated, the human eye visual response time length can be the maximum value of the image display time length, and the image display time length is the product of the number of the target images to be displayed and the image display interval, so that the maximum value of the image display interval is the ratio of the human eye visual response time length to the number of the target images to be displayed. Therefore, the image display interval ranges are [ screen refresh interval, human visual reaction time length/number of target images to be displayed ].
For example: assuming that the screen refresh interval is 1/60 second, the human visual reaction time is 1/16 second, and the number of target images to be displayed is 2, the image display interval range can be calculated as [1/60 second, 1/32 second ], and one image display interval of 1/60 second can be selected from the above range as the image display interval.
In one embodiment of the present invention, the image display interval needs to satisfy the following condition:
the screen refreshing interval is less than the image display time length and less than the human eye visual reaction time length.
The image display duration is equal to the product of the image display interval and the number of the target images to be displayed.
Specifically, since the human eye visual reaction duration is the minimum duration for the human eye to perceive the image switching, in order to make it difficult for the user to perceive the image switching process, the display duration of each image needs to be less than the human eye visual reaction duration; in addition, since the screen refresh interval is the minimum value of the image switching interval, the above-described image display time period needs to be longer than the screen refresh interval.
Based on the above, when the image display interval is determined, the range of the image display time length can be determined according to the screen refreshing interval and the human eye visual reaction time length, and the image display interval is determined according to the determined range and the number of the target images to be displayed.
Specifically, when displaying each image to be displayed, the display order of the target images to be displayed may be determined first, and then each target image to be displayed may be displayed in a cycle in sequence according to the determined display order and the image display interval. The target images to be displayed can be displayed in sequence within a preset time period according to the determined display sequence and the image display interval.
When the display order of each target image to be displayed is determined, the display order of each target image to be displayed may be randomly determined. Or the position sequence of the corresponding area of the first image area in the original image in each target image to be displayed.
When the target images to be displayed are sequentially displayed according to the preset image display interval, when the number of the target images to be displayed is larger, the frame rate of the video playing the target images to be displayed is higher.
As can be seen from the above, when the scheme provided by this embodiment is applied to image display, at least two target images to be displayed are generated according to an original image to be displayed, and the target images to be displayed are sequentially displayed according to a preset image display interval. The target image to be displayed comprises the content of the first image area and the content of the second image area, and the content of the first image area is as follows: the content of the second image area is: the processed image content contained in the corresponding area in the original image, that is, only part of the content in the original image is reserved in the target image to be displayed. Therefore, when the user performs operations such as screen capture and photographing, only partial image content in the original image can be obtained, and the complete image content of the original image cannot be obtained, so that the probability of image leakage is reduced.
In addition, the content of the image contained in the original image can be obtained due to the content superposition of the first image area in the target image to be displayed. Therefore, when the target images to be displayed are sequentially displayed according to the preset image display interval, the user can visually think that the original images are displayed currently, and the user can see the original images.
Referring to fig. 3, fig. 3 is a schematic flowchart of a second image display method according to an embodiment of the present invention. On the basis of the above embodiment, the above S102 may include S102a1-S102a 4.
S102a 1: and adjusting the pixel value of the original image to obtain an adjusted image.
In an embodiment of the present invention, the original image may be blurred to obtain an adjusted image.
Taking fig. 4 as an example, fig. 4 is a schematic diagram of adjusting an image according to an embodiment of the present invention. The image of fig. 4 is an adjusted image obtained by applying gaussian blur processing to the image of fig. 2 a.
Specifically, the blurring process may include a gaussian blurring process, a mosaic blurring process, or the like. When the original image is subjected to Gaussian blur processing to obtain the Gaussian blur image, and the target image to be displayed is obtained based on the obtained Gaussian blur image and the original image, the target image to be displayed can be smoother when the image is displayed, and therefore the display effect is closer to the original image.
In an embodiment of the present invention, transparency adjustment processing may be further performed on the original image to obtain an adjusted image.
Specifically, when transparency adjustment is performed, the pixel value of each pixel point in the original image can be adjusted, so that an adjusted image is obtained.
In adjusting the transparency, the transparency of the original image may be adjusted to 80%, 50%, or the like.
And S102A2, dividing the original image into a first preset number of original image areas according to a preset area division rule.
The preset region division rule may be set by a worker according to experience. For example: the preset region division rule may be horizontal division, longitudinal division, cross division, or division based on the region where the object is located in the original image.
The first preset number may be set by a worker according to experience, for example: the first predetermined number may be 2, 4, 8, etc.
S102a 3: and combining the image contents corresponding to each original image area in the original image to obtain a second preset number of original image contents.
The second predetermined number is greater than or equal to 2, and the first predetermined number may be greater than or equal to the second predetermined number. For example: when the second predetermined number is 4, the first predetermined number may be 4, 6, 8, etc. The second preset number may be the same as the number of the target images to be displayed.
Specifically, when the combination is performed, image contents corresponding to adjacent original image areas in the original image may be combined, image contents corresponding to the original image areas in the original image may also be combined according to a preset interval, and image contents corresponding to the original image areas in the original image may also be combined according to a random combination manner.
And S102A4, replacing the content of the first image area in the adjusted image with the original content to obtain a target image to be displayed aiming at each original content.
The first image area is: the area in the adjusted image that is in the same position in the original image as the original content.
Specifically, during replacement, the pixel values of the pixels of the original content in the original image may be obtained, and the pixel values are used as the pixel values of the pixels of the content of the first image region in the adjusted image, so as to obtain a target image to be displayed.
In this way, after the image contents corresponding to the original image areas are combined to obtain a preset number of original contents, the contents of the first image area in the adjusted image are replaced by the original contents for each original content, so that the obtained target image to be displayed comprises the contents of the first image area and the contents of the second image area, and the contents of the original image can be obtained by overlapping the contents of the first image area in each target image to be displayed.
In an embodiment of the present invention, when the target to-be-displayed image is generated, the original image may be copied to obtain at least two copied images, the first image area and the second image area in each copied image are determined, and the content of the second image area in each copied image is processed, so that each target to-be-displayed image may be obtained.
In determining the first image area and the second image area of each of the copied images, the determination may be made in the following manner. In the following description, the first position is a position of a first image area in the copied image or the original image, and the second position is a position of a second image area in the copied image or the original image.
Specifically, the second position S in the first copy image can be determined first1And for S in the first copy image1And adjusting the pixel value of the image content to obtain a first target image to be displayed.
And then based on the second position S in the first copy image1Determining a second position S in the second copy image2And for S in the second copy image2And adjusting the pixel value of the image content to obtain a second target image to be displayed.
According to the mode, the second position in each copy image is determined, and the pixel value of the image content at the second position in each copy image is adjusted to obtain each target image to be displayed.
More specifically, the second position S in the first copy image is determined1In one embodiment, the first copy image may be divided into areas, for example: the second position S can be a position where a part of the region is located1。
In another embodiment, the first copy image may be subject to object recognition, and the position of the object may be regarded as the second position S1Or taking the position of the key point in the object as the second position S1。
Determining a second location S in a second copy image2Due to the second position S2Based on a second position S in the first copy1Determining that the second position S can be divided by the second copy image1The position other than the corresponding position is taken as the second position S2. The second position S may be excluded from the second copy image1The position other than the corresponding position is taken as the second position S2. In this manner, the second positions in the respective copied images are determined in sequence.
Taking the number of the target images to be displayed as 2 examples, in an embodiment of the present invention, the target images to be displayed may be generated in the following manner.
Performing Gaussian blur processing on the original image to obtain a Gaussian blur image; acquiring the content of a partial area in an original image, acquiring the content of a Gaussian blur image except the partial area, and generating a first target image to be displayed based on the acquired content; and acquiring the content of the partial area in the Gaussian blur image, acquiring the content of the original image except the partial area, and generating a second target image to be displayed based on the acquired content.
Specifically, when the first target image to be displayed is generated, the original image and the gaussian blurred image may be divided into n × n image regions with uniform size, and the content of each region is alternately obtained from the original image and the gaussian blurred image with n as a step size. For example: the content of the area 1 may be obtained from the original image first, and then the content of the area 2 may be obtained from the gaussian-blurred image, where the area 2 is: next, the content of the area 3 is obtained from the original image in the area adjacent to the area 1, where the area 3 is: the position adjacent to the above-mentioned region 2, … … is in such a way that the content of the nth region is obtained from the original image or the gaussian-blurred image, and the first target image to be displayed is generated based on the obtained content.
When generating the second target image to be displayed, according to the similar method, firstly, the content of the region 1 is obtained from the gaussian blurred image, then the content of the region 2 is obtained from the original image, then the content of the region 3 is obtained from the original image, … … is according to the method, until the content of the nth region is obtained from the gaussian blurred image or the original image, and the second target image to be displayed is generated based on the obtained content.
Therefore, the two target images to be displayed are generated based on the original image and the Gaussian blurred image, so that when the target images to be displayed are switched, the target images to be displayed can be switched more smoothly, and the image display effect is more vivid.
In an embodiment of the present invention, when the first preset number is determined according to the screen refresh interval and the human visual reaction time in the above S103, the first preset number may be determined as follows:
and calculating the number range of the target images to be displayed based on the screen refreshing interval and the human eye visual reaction duration, and then selecting one number from the number range as the number of the target images to be displayed.

In an embodiment of the present invention, first, when calculating the maximum value of the number of target images to be displayed, it may be considered that the number of target images to be displayed is equal to the image display duration/image display interval, the screen refresh interval is a minimum interval value of the image display interval, and the human eye visual response duration is a maximum value of the image display duration.
For example: assuming that the screen refresh interval is 1/60 second and the human visual reaction time period is 1/16 second, the ratio of the two can be calculated as 60/16, and since 3 is the maximum integer less than 60/16, the maximum value of the number of images targeted to be displayed is 3.
In one embodiment of the present invention, when calculating the minimum value of the number of target images to be displayed, since the number of target images to be displayed is an integer greater than 1, the minimum value of the number of target images to be displayed may be 2. When the maximum value is calculated to be 2, since the minimum value of the number of the target images to be displayed is also 2, that is, the number range of the target images to be displayed includes only one integer.
For example: following the above example, assuming that the screen refresh interval is 1/60 second and the human visual reaction time period is 1/16 second, the number range of the target images to be displayed is calculated as [2,3], and a number 2 is randomly selected from the range as the number of the target images to be displayed.
