Description

Technical Field

[0001] The present invention relates to the technical field of screen switching of electronic device display screens, and in particular to a screen switching transition method, device and medium of an electronic device display screen. Background Art

[0002] With the development of mobile internet technology, screen switching in electronic display devices has become one of the core operations of human-computer interaction. Current mainstream applications (such as short video platforms and e-book readers) generally use transition methods such as sliding switching, fading in and out, or direct jumps. These traditional methods have significant limitations in visual perception. Studies have shown that high-frequency instantaneous screen switching can cause lag in the visual system's accommodation, resulting in approximately 68% of users experiencing symptoms of visual fatigue after two hours of continuous use, specifically manifested as dry eyes and accommodation spasms.

[0003] In the field of visual perception training, Gabor patch stimulation has been shown to effectively improve the response characteristics of visual cortical neurons. However, existing training systems often use static or independent stimulus presentation modes, failing to fully integrate with everyday human-computer interaction scenarios, resulting in insufficient training compliance. Furthermore, traditional transition effects suffer from design flaws in the contrast modulation dimension: their linear luminance change curves do not match the logarithmic response characteristics of the human visual system, resulting in ineffective visual stimulation.

[0004] At present, users lack dynamic visual stimulation adjustment when using electronic devices, and long-term use can easily lead to visual fatigue, especially in high-frequency switching scenarios such as short videos and e-books. The existing transition method does not combine the visual perception function training mechanism, and cannot improve the user's contrast sensitivity and spatial frequency resolution ability through dynamic grating stimulation; the mainstream eye protection modes in the market (such as PWM dimming and color temperature adjustment) mainly focus on reducing blue light radiation, and have limited effect on alleviating dynamic visual load; existing solutions have obvious deficiencies in spatial frequency adaptability, and fail to achieve dynamic parameter adjustment based on the user's individual visual ability, which makes it difficult for patients with refractive errors to obtain effective visual adaptation support when using electronic products.

[0005] Existing patent technologies (such as the invention application with application number 202310870424.2) propose a method and device for adjusting video images. By determining the exposure value and / or white balance value and other parameter values of the target image after switching in advance before the video image switches, the corresponding adjustment can be applied to the video image according to the pre-determined parameter values at the same time as the video image switches, so that the switching of the video image and the adjustment of the corresponding parameters occur simultaneously, thereby maintaining the uniformity of the visual effect of the image when the video conference screen switches. However, its solution is not applicable to mobile electronic devices such as mobile phones and tablets, and does not involve an active training mechanism for visual perception functions.

[0006] Therefore, in reality, it is necessary to improve the existing screen switching transition method of electronic device display screens so that users can follow the screen switching transition when using the electronic device, assist in training visual perception functions and relieve visual fatigue. Summary of the Invention

[0007] In response to the above-mentioned problems, the purpose of the present invention is to provide a method, device and medium for switching transitions of screens on an electronic device display screen, which assist in training visual perception functions and relieve visual fatigue when the content screens on the electronic device display screen transition.

[0008] Embodiments of the present invention provide a method, device, and medium for transitioning screen switching of an electronic device display screen.

[0009] A first aspect: A method for switching screen transitions on a display screen of an electronic device, comprising:

[0010] When touching the touch screen of an electronic device and the screen switches, a gray sinusoidal grating stimulation image with continuously changing contrast is presented during the screen switching transition process, which is used for visual perception function training and / or relieving visual fatigue.

[0011] Optionally, the brightness of the pixel points of the gray sinusoidal grating stimulation image is constructed using a function represented by:

[0012]

[0013] Among them, l(x,y) represents the brightness of the point with coordinates (x,y) on the stimulus image, L mean is the average brightness of the grating, C l is the grating brightness contrast, f is the grating spatial frequency, DPD is the viewing angle occupied by each point in the image, θ is the grating orientation, is the grating phase.

[0014] Optionally, the gray sinusoidal grating stimulation image has grating lines of uniform thickness, which can be expressed as follows:

[0015]

[0016] Where f is the grating spatial frequency; DPD is the visual angle occupied by each point in the image;

[0017] The DPD formula is expressed as:

[0018]

[0019] Wherein, DotSize is the actual touch screen pixel size of each point in the stimulus image; distance is the distance between pixels.

[0020] Optionally, the L meanTake 0.5, and θ take π / 4 or 3π / 4.

[0021] Optionally, the brightness contrast C of the grating l The grating spatial frequency f is determined based on the contrast sensitivity curve measured by the user's visual perception function.

[0022] Optionally, the gray sinusoidal grating stimulus image:

[0023] When used for visual perception function training, the grating spatial frequency is the spatial frequency corresponding to the user on the contrast sensitivity curve when the grating brightness contrast is 0.3; the grating brightness contrast is 0.3;

[0024] When used to relieve visual fatigue, the grating spatial frequency is the spatial frequency corresponding to the user on the contrast sensitivity curve when the grating brightness contrast is 0.2, and the grating brightness contrast is 0.2.

[0025] Optionally, the gray sinusoidal grating image display method includes:

[0026] The image edge changes gradually, the background is transparent, and it covers the background picture, or the background is gray with the average brightness of the grating, covering the background picture, where:

[0027] The edge gradient process is expressed as follows:

[0028]

[0029] Where x and y are pixel coordinates, the upper left corner of the image is the coordinate origin (0,0), centerX and centerY are the pixel coordinates of the center point of the image; alpha is the transparency; if alpha<0, alpha=0 is used; and imgSize is the image size.

[0030] Optionally, the gray sinusoidal grating image display mode includes:

[0031] As the screen slides, a fade-in and fade-out effect is formed. When the screen is switched to half, the grating image is fully displayed; or when the screen is cut in to a set degree, the grating flashes directly, and when the screen is cut out to a set degree, the grating disappears directly.

[0032] A second aspect: An electronic device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the method provided in the first aspect when executing the program.

[0033] A third aspect: A non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the method provided in the first aspect.

[0034] Beneficial effects of the present invention:

[0035] 1. This invention provides personalized visual stimulation by dynamically adjusting the brightness contrast and spatial frequency of a sinusoidal grating based on the user's contrast sensitivity curve. In training mode, the sinusoidal grating corresponding to the user's extreme spatial frequency at a specific contrast ratio is selected to specifically enhance the user's perception of detail, thereby improving visual perception.

[0036] 2. Targeted at alleviating visual fatigue, this technology combines low contrast with the highest spatial frequency discernible to the user, reducing the visual impact of screen switching through gentle brightness changes. The continuous transition of the sinusoidal grating, rather than a hard cut, reduces the sudden stress of retinal imaging, relieves ciliary muscle tension, and alleviates visual fatigue.

[0037] 3. The present invention is compatible with mainstream interactive modes such as short video sliding and e-book page turning, supports gradient overlay, and superimposes transparent edge grating on the original screen to maintain content visibility; background masking uses average brightness gray as the base to reduce the stimulation of light and dark differences when content switches, and cooperates with the display strategy of gradual entry and exit or flashing to adapt to different user operating habits and adapt to multi-scenario applications.

[0038] 4. The grating parameters of the present invention strictly follow the visual science indicators, spatial frequency quantization, and conform to the human eye perspective calculation model; the azimuth angle is optimized to enhance the grating recognition while avoiding orthogonal interference; the average brightness simulates the natural grayscale, reducing the risk of glare in dark environments, and has strong adaptability to visual physiological parameters.

[0039] 5. The transition effect of the present invention is linked to the user operation in real time, ensuring the temporal and spatial consistency of visual stimulation and action intention, strengthening the neural adaptability training of the perception-motor system, and achieving the dual goals of visual function training and eye health protection while ensuring a smooth user experience through scientifically designed visual stimulation parameters and dynamic interaction logic.

[0044] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0045] Currently, users lack dynamic visual stimulation adjustments when using electronic devices, and long-term use can easily lead to visual fatigue, especially in high-frequency switching scenarios such as short videos and e-books; existing transition methods do not combine visual perception function training mechanisms, and cannot improve users' contrast sensitivity and spatial frequency resolution capabilities through dynamic grating stimulation.

[0046] To address the above issues, the present invention provides a method for transitioning screen switching on a display screen of an electronic device. The method is applicable to electronic devices including mobile phones, e-book devices, and tablet computers. The method comprises:

[0047] When touching the touch screen of an electronic device and the screen switches, a gray sinusoidal grating stimulation image with continuously changing contrast is presented during the screen switching transition process, which is used for visual perception function training and / or relieving visual fatigue.

[0048] This method can be applied to screen transitions when swiping up and down in short video apps, when turning pages in e-books, and when other electronic display content is continuously moved or directly switched in block areas. The method uses gray sinusoidal grating images to form patches as stimulus images to train users' visual perception functions or relieve visual fatigue.

[0049] The brightness construction function of each pixel of the gray sinusoidal grating image is expressed as:

[0050]

[0051] Among them, l(x,y) represents the brightness of the point with coordinates (x,y) on the image, L mean is the average brightness of the grating, C l is the grating brightness contrast, f is the grating spatial frequency, DPD is the visual angle occupied by each point in the image (unit: "degrees / point"), θ is the grating orientation (i.e., the auxiliary feature used for stimulus identification), is the grating phase.

[0052] Preferably, L mean Take 0.5, and θ take π / 4 or 3π / 4.

[0053] The gray sinusoidal grating stimulus image has uniform grating line thickness, and the formula is:

[0054]

[0055] Where f is the grating spatial frequency; DPD is the visual angle occupied by each point in the image;

[0056] The DPD formula is expressed as:

[0057]

[0058] Where DPD is the visual angle occupied by each point in the image, DotSize is the actual pixel size of the touch screen for each point in the stimulus image, and distance is the pixel distance.

[0059] In the gray sinusoidal grating image, the brightness contrast C of the grating l The grating spatial frequency f is determined based on the contrast sensitivity curve measured by the user's visual perception function.

[0060] like Figure 3 As shown, the contrast sensitivity curve can be obtained by using existing mature equipment such as the contrast sensitivity tester CSV-1000 to evaluate the user's contrast sensitivity curve, establish a user visual profile, record the user's discernible frequency, and form a corresponding contrast sensitivity curve.

[0061] Further, such as Figure 3 As shown, according to the user's usage, when used for visual perception function training, the contrast on the contrast sensitivity curve is 20 (corresponding to C l =0.3), the spatial frequency of the sinusoidal grating that can be distinguished by both eyes is denoted as f t , the grating brightness contrast is 0.3, and θ randomly takes 0, π / 4, π / 2 or 3π / 4 gratings as stimulus images to cover more users.

[0062] When used to relieve visual fatigue, take the contrast of 5 on the contrast sensitivity curve (corresponding to C l =0.2), the spatial frequency of the sinusoidal grating that can be distinguished by both eyes is denoted as f r , the grating brightness contrast is set to 0.2, and θ randomly takes 0, π / 4, π / 2 or 3π / 4 gratings as stimulus images to cover more users.

[0063] For a better understanding, the brightness contrast C of the grating stimulus is l The acquisition principle is introduced;

[0064] Brightness contrast C l , the formula is expressed as:

[0065]

[0066] Among them, l(max) represents the maximum brightness of the grating stimulus, and l(min) represents the minimum brightness of the grating stimulus;

[0067] Regarding the luminance l of the grating stimulus image, it's important to note that due to the variability of display device hardware settings (for example, the "brightness," "color," "color temperature," and "eye protection mode" settings on mobile devices) and the effects of display device hardware aging over time, the luminance distribution of the display device at different hardware brightness levels will continuously change during use. Therefore, regular measurement of the display device is essential to ensure the accuracy of visual stimulus presentation.

[0068] The hardware brightness level of a display device is usually determined by the display bit depth. When the display bit depth is 8 bits, the hardware brightness level of the display device is divided into 2^8 = 256 levels; when the display bit depth is 10 bits, the hardware brightness level of the display device is divided into 2^10 = 1024 levels. To put it more intuitively, when the display bit depth is 8 bits, the 256 hardware brightness levels correspond to the brightness of the 256 cases in the color palette "r = 0, g = 0, b = 0", "r = 1, g = 1, b = 1" to "r = 255, g = 255, b = 255"; when the display bit depth is 10 bits, the 1024 hardware brightness levels correspond to the brightness of the 1024 cases in the color palette "r = 0, g = 0, b = 0", "r = 1, g = 1, b = 1" to "r = 1023, g = 1023, b = 1023".

[0069] Without special processing, the default setting used by display devices when displaying images is "a linear relationship between RGB values and brightness." In other words, the actual brightness corresponding to the display device's default setting of "r=200, g=200, b=200" is twice the actual brightness corresponding to "r=100, g=100, b=100." However, this is not the case. For the vast majority of display devices, the actual brightness corresponding to "r=200, g=200, b=200" is more than twice the actual brightness corresponding to "r=100, g=100, b=100." The relationship between the actual display brightness value corresponding to the 256 hardware brightness levels and the RGB value is often a power function relationship. In a few cases, it is a more complex curve relationship, such as an S-shaped curve. Such a setting is conducive to highlighting more brightness levels when presenting images, but it is not conducive to accurately controlling the brightness of visual stimuli.

[0070] In order to improve the scope of application and accuracy, the default settings of the display device cannot be used to present visual stimuli. The present invention uses a piecewise power function to evaluate the correspondence between the hardware brightness level and the actual brightness.

[0071] After regular measurement and evaluation, the theoretical brightness value of the visual stimulus required to be presented (C l)" and the "hardware brightness level value that meets the requirements". On this basis, the brightness value required to be presented at each pixel of the visual stimulus generated by the visual stimulus generation module can be converted into the hardware brightness level value that meets the requirements and accurately presented.

[0072] The specific evaluation and conversion methods are as follows:

[0073] First, with the display device hardware settings fixed, measure and record the actual screen brightness at each hardware brightness level, according to the hardware brightness level indicated by the display device bit depth.

[0074] Then, use the formula to fit the evaluation data:

[0075]

[0076] Where l is the measured screen brightness, x is the hardware brightness level, a1, a2, b1, and BP are all fitting parameters, and min(·) is the minimum value function.

[0077] When presenting visual stimuli, the theoretical brightness value of the visual stimulus transmitted from the visual stimulus generation module is converted into the hardware brightness level that should be used in actual presentation according to the above formula.

[0078] It should be noted that the hardware brightness level calculated according to the above formula is often a non-integer, but the hardware brightness level actually used by the display device must be a positive integer. Therefore, in actual operation, rounding is usually used. From this perspective, there is often a certain deviation between the actual brightness presented and the theoretical calculated value. To effectively reduce this deviation, the display bit depth of the display device should be at least 10 bits, and the higher the better.

[0079] Further, such as Figure 1 As shown, there are two ways to display gray sinusoidal grating images: one is edge gradient, background transparency, and covering the background image. The process includes:

[0080] First, calculate the distance dist between each pixel of the image and the center point of the image

[0081]

[0082] Where x, y are pixel coordinates, the upper left corner of the image is the coordinate origin (0,0), centerX, centerY are the pixel coordinates of the center point of the image

[0083] Calculate the transparency value alpha of the pixel

[0084]

[0085] When alpha<0, alpha=0, and imgSize is the image size.

[0086] Get the transparency value alpha of the pixel and save it.

[0087] Another example Figure 2 As shown, the background is gray with an average brightness of the grating, for example, the background is "r=186, g=186, b=186", covering the background picture.

[0088] Furthermore, the gray sinusoidal grating image display method includes: forming a fade-in and fade-out effect as the picture slides, and when the picture is switched to half, the grating image is fully displayed; or when the picture is cut in to a set degree, the grating directly flashes, and when the picture is cut out to a set degree, the grating directly disappears. For example, when the switching range reaches 20% of the screen range, the grating directly flashes, and when the switching is about to be completed, for example, when the new picture has been displayed 80%, the grating directly disappears.

[0089] The present invention also provides an electronic device, Figure 4 A schematic diagram of the structure of an electronic device provided by an embodiment of the present invention, such as Figure 4 As shown, the electronic device may include: a processor, a communications interface, a memory, and a communication bus, wherein the processor, the communications interface, and the memory communicate with each other via the communication bus.
