[0036] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0037] Existing electronic whiteboards are prone to visual fatigue during long-term use, especially high-brightness blue light radiation may cause damage to the user's eyes. At present, most electronic whiteboards have a low blue light mode. Although the blue light radiation can be reduced when the low blue light mode is turned on, the low blue light output is directly applied to the entire display screen, resulting in an overall decrease in the blue light component of the entire display screen, which seriously affects the display effect and color reproduction of the main object area in the display screen, making the user's visual experience very poor.

[0038] In order to solve the above problem, this embodiment proposes an asymmetric blue light suppression method, which can allow different image areas on the electronic whiteboard display screen to have different blue light outputs, thereby reducing blue light radiation while maintaining image quality.

[0039] like Figure 1 As shown, the asymmetric blue light suppression method of this embodiment specifically includes the following steps:

[0040] Step S1: Obtain image data of an image to be processed, perform pixel brightness analysis on the image data, determine the brightness distribution result of the image to be processed, divide the image to be processed into multiple image areas according to the brightness distribution result, and calculate the average brightness of each image area; wherein the brightness level corresponding to each image area is different.

[0041] Combination Figure 2 As shown, upon receiving a low blue light mode request, the system obtains image data of an image to be processed from the electronic whiteboard, wherein the image data includes image contents such as text and icons.

[0042] After receiving the low blue light mode request, the system's VBO (Visual Based Output) output module is pre-initialized and configured to the low blue light output mode; in the low blue light output mode, the blue light output of the image to be processed will be automatically adjusted to reduce the user's blue light exposure.

[0043] The system performs brightness analysis on the collected image data, generates a brightness histogram of the image to be processed, and divides the image to be processed into multiple image areas with different brightness levels based on the brightness histogram.

[0044] It should be noted that the brightness histogram is usually a bar graph, with the horizontal axis representing the brightness value (0-255) and the vertical axis representing the number of pixels of the brightness value; wherein the brightness value 0 represents black and 255 represents white. In this embodiment, the "brightness" referred to in the descriptions of "brightness value" and "brightness level" represents the grayscale of each pixel in the image to be processed. The brightness value of the brightness histogram is used to analyze the pixel value distribution of the image to be processed, which is a different concept from the "overall screen brightness" of the electronic whiteboard. The overall screen brightness is not only related to the pixel value of the image to be processed, but also to factors such as the backlight intensity and color calibration of the display screen.

[0045] In order to achieve image segmentation, according to the brightness histogram, a suitable threshold is pre-selected to define image areas of different brightness levels. For example, in this embodiment, the image area is divided into a high brightness area and a low brightness area, and the high brightness threshold of the high brightness area is pre-set to any value in the range of 180 to 200; similarly, the low brightness threshold of the low brightness area is pre-set, and the low brightness threshold can be set to any value in the range of 50 to 80.

[0046] The specific values ​​of the high brightness threshold and the low brightness threshold can be set according to the actual conditions such as the device and the environment, and the specific values ​​of the thresholds are not limited here.

[0047] In this embodiment, the number of pixels corresponding to different brightness values ​​is determined based on the brightness histogram;

[0048] Mark the pixels whose brightness value is higher than or equal to the preset high brightness threshold, and determine the high brightness area according to the position of the high brightness pixel;

[0049] Pixels whose brightness values ​​are lower than a preset low brightness threshold are marked, and the low brightness area is determined according to the position of the low brightness pixels.

[0050] It should be noted that the image area can also be divided into image areas with more brightness levels. It only needs to set the threshold corresponding to each brightness level in advance. When the threshold judgment is met, the image area can be divided into image areas with more brightness levels.

[0051] Step S2: Determine the suppression weight of each image area according to the brightness level corresponding to each image area, and calculate the blue light suppression coefficient of each image area through the suppression weight and the average brightness.

[0052] Pre-configure appropriate suppression weights for different brightness levels, and the suppression weights can be set by empirical values. Generally speaking, the high brightness suppression weights in high brightness areas can be set between 0.5 and 0.8, while the low brightness suppression weights in low brightness areas can be set between 0.2 and 0.5. This setting can reduce blue light radiation to a large extent while retaining appropriate color reproduction.

[0053] After distinguishing the high brightness area and the low brightness area, the brightness values ​​of all pixels in each image area are averaged to obtain the average brightness of each image area.

[0054] When the image area is a high brightness area, a high brightness suppression weight of the pre-configured high brightness area is obtained, and the product of the high brightness suppression weight and the average brightness of the image area is calculated to obtain a blue light suppression coefficient of the high brightness area;

[0055] When the image area is a low brightness area, obtain the pre-configured low brightness suppression weight of the low brightness area, calculate the product of the high brightness suppression weight and the average brightness of the image area, and obtain the blue light suppression coefficient of the low brightness area. The corresponding formula is as follows:

[0056] Chigh=Khigh*Lhigh;

[0057] Clow=Klow*Llow.

[0058] Where Chigh: blue light suppression coefficient in high brightness area;

[0059] khigh: suppression weight of high brightness area;

[0060] Lhigh: average brightness of high brightness area;

[0061] Clow: blue light suppression coefficient in low brightness area;

[0062] klow: suppression weight of low brightness area;

[0063] Llow: The average brightness of low brightness areas.

[0064] Step S3: determining the original blue light component of each image area according to the image data, and adjusting the original blue light component of each image area based on the blue light suppression coefficient of each image area to obtain a display image with multiple blue light outputs. Specifically:

[0065] Step S31: determining the original blue light component of the image area according to the image data, calculating the product between the blue light suppression coefficient of the image area and the original blue light component of the image area, and obtaining the blue light suppression amount of the image area.

[0066] Step S32: Calculate the difference between the original blue light component of the image area and the blue light suppression amount of the image area, and adjust the blue light output of the image area according to the difference.

[0067] The original blue light component is obtained according to the image data of the image to be processed. The original blue light component is a basic component of the image to be processed. Together with the red and green components, it can produce various colors through different combinations and intensities.

[0068] When the image area is a high-brightness area, a higher blue light suppression coefficient is applied to the high-brightness area, so that the blue light suppression amount in the high-brightness area is relatively large. At this time, the blue light output in the high-brightness area can be relatively significantly reduced, thereby achieving the purpose of reducing blue light radiation; while a lower blue light suppression coefficient is applied to the low-brightness area, and the blue light suppression amount in the low-brightness area is relatively small. At this time, the blue light output in the low-brightness area can be adjusted relatively slightly, or even maintain the default or preset value of the blue light output to retain more blue light, thereby ensuring that the image to be processed maintains a good display effect and color reproduction, and maintains image quality.

[0069] In some embodiments, in order to ensure the display quality of the main object area in the image to be processed, an edge detection algorithm (such as the Canny edge detection algorithm) is used to process the image to be processed to identify the edge and main object area in the image to be processed. The area corresponding to the main object is accurately divided through the identified edge information to obtain the object area. The main object can be a display object such as text, graphics, etc. in the image to be processed.

[0070] After determining the object area in the image to be processed, determine whether the object area is in a high-brightness area or a low-brightness area based on the brightness distribution of the pixels in the object area; if the object area is a high-brightness area, apply the aforementioned blue light suppression method for high-brightness areas to perform blue light adjustment; if the object area is a low-brightness area, apply the aforementioned blue light suppression method for low-brightness areas to perform blue light adjustment; the suppression weight of the object area can even be pre-configured, and its suppression weight can be different from the suppression weight of the high-brightness area and the suppression weight of the low-brightness area. The corresponding blue light suppression coefficient is calculated based on the specific suppression weight of the object area, thereby adjusting the blue light component of the object area to make the display effect of the object area better.

[0071] Furthermore, different suppression weights can be pre-configured for object areas of different object types. When the object type of the object area is determined to be a graphic, since the graphic display needs to highlight its color reproduction, the graphic object area can be adjusted for blue light according to the blue light suppression method of the low-brightness area to retain more blue light and maintain the color reproduction of the image; if the object type is black and white text without color features, the text object area can be adjusted for blue light according to the blue light suppression method of the high-brightness area to reduce blue light radiation.

[0072] It should be noted that the suppression weights configured for different types of object areas and the corresponding blue light suppression strategies can be pre-configured to achieve different blue light outputs for different areas on the same display screen.

[0073] After processing blue light suppression, the system performs quality correction on the processed image to ensure the color reproduction and consistency of the overall image. Then, the VBO output module is used to output the final processed image data to ensure that the image still has a good display effect in low blue light mode.

[0074] In some embodiments, the PWM (Pulse Width Modulation) dimming module of the electronic whiteboard can also be initialized. This module is responsible for controlling the overall screen brightness of the electronic whiteboard. After receiving the dimming instruction generated according to the user operation, the dimming mode adjusts the duty cycle of the PWM signal according to the dimming instruction, thereby adjusting the overall screen brightness of the electronic whiteboard and achieving fine adjustment of the brightness.

[0075] In one embodiment, in the process of applying the blue light suppression coefficient, the color distortion of the displayed image is judged in real time. If it is found that the processed image has obvious color distortion, the system will dynamically adjust the blue light suppression coefficient until the distortion is eliminated to ensure that the image quality meets the expected standard. The adjustment ratio of the dynamic adjustment of the blue light suppression coefficient can be preset, that is, the adjustment amplitude of the blue light suppression coefficient corresponding to different degrees of color distortion is preset. When the distortion is detected, the system maps the corresponding adjustment amplitude and adjusts the blue light suppression coefficient according to the adjustment amplitude until the distortion is eliminated.

[0076] In addition, the system also provides a user interface for image display settings, through which users can adjust the intensity of the low blue light mode and the image brightness. The user's choice will directly affect the parameter settings of the VBO output and PWM dimming modules. The system processes and displays the adjusted image effects in real time, and users can choose the display mode that best suits long-term use according to their own needs.

[0077] The present invention can divide the content displayed by the electronic whiteboard into multiple image areas according to the pixel brightness distribution of the electronic whiteboard, and adjust the blue light component of each image area according to the blue light suppression coefficient of each image area, so that different image areas on the entire electronic white screen can have different blue light outputs, achieving an asymmetric blue light suppression effect, and maintaining image quality while reducing blue light radiation.
