The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0046] The image display method, device, electronic device, chip, and storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.

[0047] Figure 1 A schematic diagram of an image display process provided in an embodiment of the present application.

[0048] As an implementation manner, the image display method of the embodiment of the present application can be configured in an image display device, and the image display device can be applied to any electronic device so that the electronic device can perform an image display function.

The mobile terminal can be, for example, a mobile phone, tablet computer, personal digital assistant, wearable device, or other hardware device with various operating systems, touch screens and / or display screens.

[0051] It should be noted that the collection of user-related data in this application is carried out with the user's authorization and strictly abides by relevant laws and regulations such as privacy and security.

[0052] like Figure 1 As shown, the method may include the following steps:

[0053] Step 101, determining pixels to be adjusted based on the tone parameters of pixels in the image;

[0054] Step 102: reducing the first brightness parameter of the pixel to be adjusted to a second brightness parameter;

[0055] Step 103: Display the image according to the adjusted second brightness parameter.

[0056] In this embodiment, the method disclosed herein is used in an electronic device including an organic light-emitting display panel, or in a semiconductor chip that drives the display of the organic light-emitting display panel.

[0057] In this embodiment, based on the hue parameters of each pixel in the image, specific judgment rules and algorithms are first used to accurately screen and determine the pixels that need to be adjusted for brightness adjustment. This process involves a detailed analysis of the color composition of the image, and by interpreting the hue information of the pixels, the pixels that have a key impact on the overall visual experience of the image are identified.

[0058] Next, for each pixel identified for adjustment, its initial first brightness parameter is reduced according to a pre-set adjustment strategy, transforming it into a second brightness parameter. This reduction process is an optimization adjustment based on a comprehensive consideration of multiple factors, including image display requirements and color balance, ensuring that the brightness reduction does not adversely affect the overall image display quality.

[0059] Finally, the image is displayed based on the adjusted second brightness parameter. At this time, the image will be more in line with the expected display effect in terms of visual presentation because the brightness of the pixels to be adjusted has been reasonably optimized.

[0060] In one possible embodiment, the pixel to be adjusted emits blue light. During display operation, for a given current density, blue luminescent materials have a shorter lifetime than red or green luminescent materials. Based on the human eye's visual perception, blue sub-pixels provide the least brightness and spatial detail compared to red and green light. Reducing blue brightness can reduce power consumption without significantly degrading perceived display quality. Reducing blue light can effectively minimize eye damage when viewing the screen.

[0061] Optionally, the hue parameters of the pixels in the image are parameters in the HSV color space. The parameters in the HSV color space include hue (H), saturation (S), and brightness (V). The hue H represents color information, that is, the position of the spectral color. Based on the hue H, it can be determined whether the color of the pixel is blue.

[0062] This embodiment adjusts the brightness parameter of the pixel to be adjusted, reducing the first brightness parameter of the pixel to be adjusted to the second brightness parameter to reduce the display brightness of the pixel to be adjusted, thereby reducing the energy consumption of displaying the image without affecting the overall display effect of the image.

[0063] In one embodiment of the present disclosure, the adjustment parameter includes a first adjustment parameter and a second adjustment parameter, and reducing the first brightness parameter of the pixel to be adjusted to the second brightness parameter includes:

[0064] determining a brightness retention ratio according to the first adjustment parameter and the second adjustment parameter; the first adjustment parameter is used to control an upper limit of an adjustment degree, and the second adjustment parameter is used to control a lower limit of an adjustment degree; the brightness retention ratio is used to control a retention degree of the first brightness parameter;

[0065] The first brightness parameter is adjusted according to the brightness retention ratio to obtain the second brightness parameter.

[0066] In this embodiment, the clear adjustment parameters include a first adjustment parameter K and a second adjustment parameter L. These two parameters play a core control role in the brightness adjustment process and are used to limit the upper and lower limits of the adjustment degree respectively, ensuring that the brightness adjustment is carried out within a reasonable and controllable range.

[0067] In the crucial step of reducing the first luminance parameter of the pixel to be adjusted to the second luminance parameter, the luminance retention ratio D must first be determined based on the first adjustment parameter K and the second adjustment parameter L. Specifically, this determination involves in-depth analysis and calculation of the numerical relationship between the two adjustment parameters and their functional positioning in the luminance adjustment system. Using a specific mathematical model or algorithm, the luminance retention ratio D is accurately calculated based on the values ​​of K and L. This ratio directly determines the degree of luminance retention of the pixel to be adjusted after the luminance is reduced, thereby affecting the final image display effect.

[0068] Then, the first luminance parameter V1 of the pixel to be adjusted is adjusted based on the determined luminance retention ratio D, thereby obtaining a second luminance parameter V2 that meets the desired display effect. This adjustment process is a targeted numerical transformation of the original luminance parameter based on the luminance retention ratio to achieve fine-tuning of the pixel luminance, resulting in a more ideal light-dark contrast and color gradation when the image is displayed.

[0069] Optionally, the first adjustment parameter is greater than the second adjustment parameter, and determining the brightness retention ratio according to the first adjustment parameter and the second adjustment parameter includes:

[0070] Calculating a first difference between the first adjustment parameter and the second adjustment parameter, and calculating a second difference between the upper limit of brightness and the second adjustment parameter, and determining the adjustment coefficient according to a ratio of the first difference to the second difference;

[0071] The brightness retention ratio is determined according to the adjustment coefficient, the first brightness parameter of the pixel to be adjusted, and the second adjustment parameter.

[0072] In this embodiment, the numerical relationship between the first adjustment parameter K and the second adjustment parameter L is clarified, that is, the first adjustment parameter K is greater than the second adjustment parameter L. This setting provides a basic numerical premise for the subsequent brightness retention ratio calculation, ensuring the rationality and feasibility of the brightness adjustment process.

[0073] In the step of determining the brightness retention ratio according to the first adjustment parameter and the second adjustment parameter, the specific steps are as follows:

[0074] First, a first difference between the first adjustment parameter and the second adjustment parameter is calculated, that is, K minus L to obtain (KL). The difference reflects the numerical span between the two adjustment parameters and embodies the adjustable range of the adjustment degree.

[0075] At the same time, the second difference between the upper limit of brightness (usually 1, representing the highest brightness level) and the second adjustment parameter L is calculated, that is, 1 minus L to obtain (1-L). This difference is related to the potential variable space of the brightness parameter during the adjustment process.

[0076] Next, the adjustment coefficient M = (KL) / (1-L) is determined based on the ratio of the first difference (KL) to the second difference (1-L). The adjustment coefficient M, as a key intermediate parameter, directly affects the subsequent calculation of the brightness retention ratio. By calculating the ratio of the two differences, the adjustment parameter and the brightness upper limit are organically combined, allowing the adjustment coefficient to fully reflect the adjustment parameter's impact on brightness adjustment and the relative degree of brightness change.

[0077] Finally, the brightness retention ratio is comprehensively determined based on the determined adjustment coefficient M, the first brightness parameter of the pixel to be adjusted, and the second adjustment parameter L.

[0078] In a possible embodiment, the value range of K and L is [0, 1], and K> L. It should be noted that when implementing the solution in this application, the values ​​of K and L can be adjusted according to needs.

[0079] This comprehensive calculation process fully integrates all relevant factors, fully considering the original brightness characteristics of the pixel itself, the control intention of the adjustment parameters, and the extreme range of brightness change, so as to obtain an accurate and reasonable brightness retention ratio, providing a key basis for subsequent brightness adjustments, ensuring that the image display effect can achieve the expected optimization goals and realize high-quality visual presentation.

[0080] Optionally, determining the brightness retention ratio according to the adjustment coefficient, the first brightness parameter of the pixel to be adjusted, and the second adjustment parameter includes:

[0081] performing normalization processing on the first brightness parameter, and obtaining a third difference between the first brightness parameter after normalization processing and the second adjustment parameter;

[0082] The third difference is weighted according to the adjustment coefficient, and the weighted third difference is added to the second adjustment parameter to obtain the brightness retention ratio.

[0083] In this embodiment, the first luminance parameter is first normalized, i.e., the first luminance parameter V1 is divided by 255 to obtain the normalized first luminance parameter (V1 / 255). The purpose of this normalization operation is to standardize the value range of the luminance parameter to the interval [0,1], facilitating subsequent mathematical operations and ratio calculations. It also enables the luminance parameters of different pixels to be compared and processed at the same scale, thereby improving the accuracy and reliability of the calculation.

[0084] Next, a third difference between the normalized first brightness parameter and the second adjustment parameter L is calculated, i.e., (V1 / 255-L). This difference reflects the difference between the original brightness of the pixel to be adjusted and the lower limit adjustment parameter L under the normalized brightness scale. It provides a basic value for subsequent weighting operations and reflects the relative position of the pixel brightness within the adjustment range.

[0085] Next, the third difference (V1 / 255-L) is weighted according to the adjustment coefficient M. This weighted calculation multiplies the third difference by the adjustment coefficient M to obtain the weighted third difference. This weighting step fully accounts for the influence of the adjustment coefficient M on the brightness adjustment. By combining the difference with the adjustment coefficient, the subsequently calculated brightness retention ratio reflects the differential control of the adjustment parameter on the brightness adjustment of different pixels, further improving the accuracy and adaptability of brightness adjustment.

[0086] Finally, the weighted third difference is added to the second adjustment parameter L to obtain the final brightness retention ratio D = M * (V1 / 255 - L) + L. This step integrates the influence of the adjustment coefficient on the brightness difference by adding the weighted difference to the lower limit adjustment parameter. Combined with the lower limit adjustment parameter, this ensures that the value of the brightness retention ratio D not only meets the control requirements of the adjustment parameter but also reasonably reflects the original brightness characteristics of the pixel. This provides a scientific, accurate, and practical reference value for subsequent brightness adjustments, allowing the image to retain a certain amount of blue light during display without affecting the overall display effect.

[0087] Optionally, the adjusting the first brightness parameter according to the brightness retention ratio to obtain the second brightness parameter includes:

[0088] Obtaining a fourth difference between the first brightness parameter and the brightness retention ratio after normalization;

[0089] weighting the fourth difference according to the saturation parameter of the pixel to be adjusted to obtain a brightness reduction ratio;

[0090] The first brightness parameter is reduced according to the brightness reduction ratio to obtain the second brightness parameter.

[0091] In this embodiment, first, a fourth difference between the normalized first luminance parameter (V / 255) and the luminance retention ratio D is obtained, i.e., (V / 255-D) is calculated. This difference reflects the difference between the original luminance of the pixel to be adjusted and the ideal luminance determined by the retention ratio under the normalized scale. It provides a specific numerical basis for the subsequent luminance reduction operation and clarifies the magnitude of the luminance reduction to be performed.

[0092] Next, the fourth difference (V / 255-D) is weighted according to the saturation parameter of the pixel to be adjusted to obtain the brightness reduction ratio S*(V / 255-D). The introduction of the saturation parameter S as a weighting factor fully takes into account the correlation between saturation and brightness in color perception. Generally speaking, when the brightness of a highly saturated color changes, the sensitivity of the human eye to its brightness changes will be different. Therefore, weighting the brightness reduction ratio by the saturation parameter can make the brightness adjustment more in line with the visual characteristics of the human eye and achieve a more natural and realistic color display effect. Specifically, according to the saturation value S of the pixel to be adjusted, it is multiplied by the fourth difference to obtain a brightness reduction ratio after saturation adjustment. This ratio can comprehensively reflect the influence of the saturation characteristics of the pixel on the degree of brightness reduction, making the brightness adjustment more targeted and adaptable.

[0093] Finally, the first brightness parameter is reduced according to the obtained brightness reduction ratio, thereby obtaining a second brightness parameter V2 = V1-S*(V / 255-D)*255. This final brightness adjustment calculation process converts the normalized value back to the actual brightness value range (usually 0-255). By subtracting the weighted brightness reduction value from the original brightness parameter V1, a second brightness parameter V2 that meets the requirements is obtained. This parameter will directly determine the brightness presentation of the pixel to be adjusted in the image display. After this fine adjustment, the pixel brightness not only takes into account the control intention of the adjustment parameter and the brightness and saturation characteristics of the pixel itself, but also fully considers the overall color balance and visual coordination of the image, so that the final displayed image retains a good display effect while reducing the blue brightness.

[0094] Optionally, determining the pixel to be adjusted based on the color parameters of the pixel in the image includes:

[0095] In response to the tone parameter of the pixel being within a preset parameter range, the pixel is determined to be the pixel to be adjusted.

[0096] In this embodiment, a responsive determination mechanism is employed. When the hue parameter of a pixel in an image falls within a specific preset parameter range, the system or algorithm automatically responds and identifies the pixel as a target pixel for adjustment. This determination method relies on precise monitoring and comparison of hue parameters. By scanning and analyzing the hue of each pixel in the image, the system determines whether it falls within a pre-set hue range. The preset parameter range can be flexibly set based on different image types, display requirements, and color adjustment goals. For example, to enhance the display effect of a specific hue region in an image (such as the blue sky hue range), the parameter range corresponding to that hue can be set as a preset range. When the pixel hue falls within this range, the pixel for adjustment is triggered. This responsive determination method based on hue parameter ranges can quickly and accurately screen pixels that meet specific color adjustment requirements, providing a clear target set for subsequent brightness adjustment steps. This ensures that the image display method can optimize the target hue region in a targeted manner, thereby achieving refined control over the image's color composition, improving the quality and effect of the image's specific hue representation, and meeting the display requirements for harmonious hue and brightness in different scenarios.

[0097] Optionally, the method further includes:

[0098] Converting pixels in the image from a first color space to a second color space, wherein the second color space includes a first brightness parameter, a hue parameter, and a saturation parameter of the pixels;

[0099] The adjusted second brightness parameter of the pixel is converted from the second color space to the first color space, and the image is displayed according to the parameter of the pixel in the first color space.

[0100] In this embodiment, before the pixels in the image are conditioned, the pixels in the image are converted from the first color space to the second color space. This conversion process is an important prerequisite for achieving accurate adjustment of the pixel brightness parameters, because different color spaces have different color representation methods and parameter definitions. The selection of the second color space should be able to better support the independent adjustment of the brightness parameter and the coordinated processing with other color parameters such as hue and saturation. By converting the pixels from the original first color space (such as RGB color space) to a suitable second color space, the brightness parameter can be effectively decoupled or optimized with other color parameters, making subsequent brightness adjustment operations more convenient, efficient and accurate. At the same time, it also provides a controllable environment for the mutual influence between color parameters, which is conducive to achieving overall color balance and optimization. In a possible embodiment, the first color space is RGB space, and the second color space is HSV space.

[0101] After the brightness parameter adjustment of the pixel to be adjusted is completed, the second brightness parameter of the adjusted pixel is converted from the second color space back to the first color space. This inverse conversion process ensures that the final displayed image can be correctly presented in the original color space system, because the image display device usually interprets and displays image data based on a specific color space (such as RGB color space). By accurately converting the pixel parameters after brightness adjustment back to the first color space, the display result of the image can match the color requirements of the display device, thereby ensuring that the audience can see an image that meets expectations, is color-accurate, and has appropriate brightness and darkness. This color space conversion process provides a favorable operating environment for brightness adjustment, and also ensures the correct transmission and presentation of image data in different color space systems, greatly improving the quality and reliability of image display effects, and meeting the high standards for color accuracy and visual effects in the field of modern image processing and display. In a possible embodiment, the process of converting RGB to HSV is as follows: V = max(R, max(G, B))

[0102] a) If V is equal to 0, then S = 0; if V is not equal to 0, then

[0103]

[0104] b) If V equals min(R,min(G,B)), then H equals 0.

[0105] c) If V is equal to R and G is greater than or equal to B, then

[0106]

[0107] d) If V is equal to R and G is less than B, then

[0108]

[0109] e) If V is equal to G, then

[0110]

[0111] f) If none of the above is true,

[0112]

[0113] In one possible embodiment, the process of converting HSV to RGB color space is as follows:

[0114]

[0115] C=V*S

[0116]

[0117] M=VC

[0118] a) If H is greater than or equal to 0 and less than 60, then

[0119] R0=C,G0=X,B0=0

[0120] b) If H is greater than or equal to 60 and less than 120, then

[0121] R0=X,G0=C,B0=0

[0122] c) If H is greater than or equal to 120 and less than 180, then

[0123] R0=0,G0=C,B0=X

[0124] d) If H is greater than or equal to 180 and less than 240, then

[0125] R0=0,G0=X,B0=C

[0126] e) If H is greater than or equal to 240 and less than 300, then

[0127] R0=X,G0=0,B0=C

[0128] d) If H is other, then

[0129] R0=C,G0=0,B0=X

[0130] The power calculation formula for displaying a single pixel on a monitor is as follows:

[0131] Power=a*R 2 +b*G 2 +c*B 2 +d*(R+G+B)

[0132] As the brightness decreases, the values ​​of R, B, and G converted to RGB are all reduced, so the power of the display to display the image is reduced.

[0133] In order to implement the above embodiment, the present application also provides an image display device.
