Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
It should be noted that, all actions of acquiring signals, information or data in the present application are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
As the frequency of using mobile phones increases, the probability of using mobile phones in different environments increases, for example, users moving from indoor to outdoor in the process of using mobile phones.
However, the subjective feeling of the human eyes on the same content displayed on the mobile phone is quite different under different environmental illumination, the human eyes can subjectively feel brighter and brighter color under the darkroom when viewing the same picture in the sunlight and in the darkroom, and the visual effect under the sunlight is opposite, so that the color of the picture can be perceived to be dull. Therefore, the pictures seen by the user in different environments are inconsistent in feeling, and the user experience is reduced.
In view of the above problems, embodiments of the present disclosure provide an image display method, an apparatus, an electronic device, and a storage medium, which can dynamically adjust color information of display content of a display device according to illumination intensity, thereby ensuring that a user experiences consistent subjective display effect on the display content of the display device when using the display device, avoiding situations of excessively light screen display color or excessively bright screen display in darkroom under sunlight, and further improving user experience.
Fig. 1 is a flowchart illustrating an image display method according to an exemplary embodiment, which may be used in a display device, as shown in fig. 1, and may include the steps of:
in step S11, the illumination intensity of the ambient light is acquired.
In some embodiments, a light sensor for detecting illumination intensity is configured on the display device, and the display device can detect the illumination intensity of the ambient light in the current environment through the light sensor, so as to obtain the illumination intensity of the ambient light.
Alternatively, the display device may include, but is not limited to: a mobile phone, a tablet device, a personal computer, an intelligent wearable device and other devices with display functions.
It will be appreciated that the ambient light in this embodiment may be considered as the ambient light of the environment in which the display device is located, for example, when the user is using the display device indoors, the ambient light is the ambient light detected in the indoor environment,
in step S12, a three-dimensional lookup table corresponding to the illumination intensity is determined.
In this embodiment, the LUT can play a role of color space conversion for the display, while the three-dimensional lookup Table (3D LUT) is composed of 3 one-dimensional lookup tables (1 DLUT), and the three input RGB channel color values are mapped according to the three lookup tables of the 3D LUT, so that the converted colors can be obtained, and color adjustment for the imaging result can be realized.
In some embodiments, the display device may determine a three-dimensional lookup table corresponding to the illumination intensity from a preset plurality of three-dimensional lookup tables. For example, a mapping relationship between a plurality of illumination intensities and a plurality of three-dimensional lookup tables may be pre-established, and when the display device determines the illumination intensity of the current ambient light, a corresponding target three-dimensional lookup table may be found from the plurality of illumination intensities according to the illumination intensity and the mapping relationship. As an example, the mapping relationship of the plurality of illumination intensities and the plurality of three-dimensional lookup tables may be as shown in table 1:
TABLE 1
| Intensity of illumination | Three-dimensional lookup table |
| Intensity of illumination a | Three-dimensional lookup table 1 |
| Intensity of illumination b | Three-dimensional lookup table 2 |
| Intensity of illumination c | Three-dimensional lookup table 3 |
It can be seen that a three-dimensional look-up table corresponding to the illumination intensity of the current ambient light can be found from table 1. For example, the illumination intensity is the illumination intensity b, the three-dimensional lookup table 2 may be determined as a three-dimensional lookup table corresponding to the illumination intensity b.
Alternatively, the light intensity corresponding to the three-dimensional lookup table in table 1 may have a certain error tolerance, for example, the light intensity a corresponding to the three-dimensional lookup table 1 is 100Lux, and the error tolerance is ±2Lux, and then all 98Lux to 102Lux can be regarded as the light intensity a. Alternatively, the error allowable range may be set according to actual conditions, and is not limited herein.
In step S13, fitting the three-dimensional lookup table with the target illumination intensity to obtain a target three-dimensional lookup table.
In some embodiments, a fitting function may be pre-established, where the fitting function may be capable of fitting the three-dimensional lookup table corresponding to the current illumination intensity with the target illumination intensity to obtain a target three-dimensional lookup table corresponding to the target illumination intensity, so as to ensure that H, S, V of the color in the HSV space of the fitted illumination intensity is consistent with H, S, V of the color in the HSV space of the target illumination intensity.
Among them, HSV color space is a color space created from visual characteristics of colors. H in HSV is Hue, S is Saturation, and V is Value.
In step S14, an image is displayed based on the target three-dimensional lookup table.
In some embodiments, the target three-dimensional lookup table stores a mapping relationship between the corresponding input RGB values and the corresponding output RGB values under the illumination intensity of the current ambient light. The display device may map the color information of the currently displayed image as input RGB values, the input RGB color values (i.e., input RGB values) according to three lookup tables of the 3D LUT, obtain converted colors (i.e., output RGB values), and display the image through the converted colors.
It can be seen that, in the present embodiment, the illumination intensity of the ambient light is obtained; determining a three-dimensional lookup table corresponding to the illumination intensity; fitting the three-dimensional lookup table with the target illumination intensity to obtain a target three-dimensional lookup table; and then displaying the image based on the target three-dimensional lookup table. Therefore, the three-dimensional lookup table of the display equipment can be dynamically adjusted according to different illumination intensities, the three-dimensional lookup table of the display equipment under different illumination intensities is fitted with the target illumination intensity, the target three-dimensional lookup table corresponding to the target illumination intensity is obtained, a user can feel a consistent display effect under the environment light with different illumination intensities, the conditions that the display color of the screen of the display equipment is too light or the screen of a darkroom is too bright under sunlight are avoided, and better use experience of the user is ensured.
Fig. 2 is a flowchart illustrating an image display method, which may be used in a display device, as shown in fig. 2, according to an exemplary embodiment, and may include the steps of:
in step S21, the illumination intensity of the ambient light is acquired.
The specific embodiment of step S21 can refer to step S11, and thus will not be described herein.
In step S22, the illumination intensity is input to a pre-established mapping model, and a three-dimensional lookup table output by the mapping model is obtained, wherein the mapping model is established based on a plurality of illumination intensity samples and the three-dimensional lookup table measured under the plurality of illumination intensity samples.
In some embodiments, the mapping model may be stored locally on the display device or in a cloud server communicatively coupled to the display device, from which the mapping model may be invoked when the display device needs to be used.
In some embodiments, before step S22, the image display method may further include:
respectively obtaining color coordinates corresponding to color nodes in a three-dimensional lookup table measured under a plurality of illumination intensity samples, and obtaining a three-dimensional lookup table corresponding to each illumination intensity sample;
and establishing the mapping model based on the plurality of illumination intensity samples and the three-dimensional lookup table corresponding to each illumination intensity sample.
For example, the ambient light of samples with different illumination intensities, for example, the ambient light with illumination intensities of 100Lux, 200Lux, 300Lux and … 1000Lux, may be set, and XYZ color coordinates corresponding to color nodes in the 3D LUT are measured by an optical instrument under the ambient light with different illumination intensities, so as to obtain the 3D LUT with different illumination intensities. For example, in an environment with an illumination intensity of 500Lux, XYZ color coordinates corresponding to color nodes in the 3D LUT may be measured by an optical instrument and used as the 3D LUT with an illumination intensity of 500Lux. Similarly, the 3D LUT corresponding to other illumination intensity samples such as 100Lux, 200Lux, 300Lux and the like can be obtained.
It is understood that the 3D LUT may be regarded as a cube of XYZ color coordinates corresponding to a plurality of color nodes.
In step S23, the three-dimensional lookup table is fitted to the target illumination intensity, so as to obtain a target three-dimensional lookup table.
In some embodiments, the specific embodiment of step S23 may include:
step S231, converting the color coordinates corresponding to the color nodes in the three-dimensional lookup table into an HSV color space to obtain first HSV information.
In some embodiments, the specific implementation of step S231 may include:
and converting the color coordinates corresponding to the color nodes in the three-dimensional lookup table into an RGB color space, and then converting the RGB color space into the HSV color space.
Among them, the RGB color space is the most commonly used color information expression method, in which colors are quantitatively expressed by using the brightness of the three primary colors of red, green and blue, and the color mixing method is realized by overlapping RGB three-color light. The three colors are different in proportion, and the obtained colors are different. By changing the mixing ratio, various mixing effects can be obtained.
Alternatively, the conversion between the RGB color space and the HSV color space may be performed using a conversion formula in the related art, or may be performed through a color comparison table of RGB and HSV, which is not limited herein.
For example, if the current measured illumination intensity is 300Lux, the color coordinates corresponding to the color nodes in the three-dimensional lookup table corresponding to the illumination intensity of 300Lux may be converted into an HSV color space, so as to obtain the first HSV information.
Step S232, determining second HSV information corresponding to the target illumination intensity according to the illumination intensity, the target illumination intensity and the first HSV information.
As an embodiment, the first HSV information includes a first hue, a first saturation, and a first brightness, and the specific embodiment of step S232 may include:
determining the first tone as a second tone; determining the product of the first saturation and a fitting proportion as second saturation, wherein the fitting proportion is the ratio of the illumination intensity to the target illumination intensity; determining a product of the first brightness and the fitting ratio as a second brightness; the second HSV information is obtained based on the second hue, the second saturation, and the second brightness.
Illustratively, for example, in the first HSV information corresponding to the current illumination intensity, the first hue may be represented by H 0 The first saturation may be represented by S 0 The first brightness may be represented by V 0 And (3) representing. In the second HSV information corresponding to the target illumination intensity, the second hue may be represented by H, the second saturation may be represented by S, and the second brightness may be represented by V. If the target illumination intensity is mLux and the current illumination intensity is LLux, the first HSV information may be converted to the second HSV information by a fitting function as follows:
H＝H 0 ；
S＝L*S 0 /m；
V＝L*V 0 /m。
wherein the fitting ratio is L/m.
As a specific example, taking a target illumination intensity of 500Lux as an example, the first HSV information may be converted to the second HSV information by the following function:
H＝H 0 ；
S＝L*S 0 /500；
V＝L*V 0 /500。
as another specific example, at a target illumination intensity of 500Lux, the currently measured illumination intensity of 300Lux, the first HSV information may be converted to the second HSV information by the following function:
H＝H 0 ；
S＝300*S 0 /500；
V＝300*V 0 /500。
similarly, according to the fitting function, the first HSV information corresponding to different illumination intensities and the target illumination intensity can be fitted to obtain the second HSV information corresponding to the target illumination intensity. In addition, according to the fitting formula, after the color under the current illumination intensity is fitted, H, S, V in the HSV color space is consistent with H, S, V in the HSV color space under the target illumination intensity. Because the HSV color space can reflect the visual perception of the user on the color, the display effect perceived by the user under the current illumination intensity after fitting is consistent with the display effect perceived under the target illumination intensity.
Step S233, determining the target three-dimensional lookup table based on the second HSV information.
In some embodiments, the specific implementation of step S233 may include:
and converting the second HSV information into an RGB color space, and converting the RGB color space into color coordinates corresponding to color nodes in a three-dimensional lookup table to obtain the target three-dimensional lookup table.
In some embodiments, the fitting function may be set in the mapping model, after the mapping model determines the three-dimensional lookup table corresponding to the current illumination intensity, the three-dimensional lookup table corresponding to the current illumination intensity may be fitted with the target illumination intensity by using the fitting function, and after the target three-dimensional lookup table corresponding to the target illumination intensity is obtained, the target three-dimensional lookup table is output.
Illustratively, taking the target illumination intensity of 500Lux as an example, the working process of the mapping model may be as shown in fig. 3:
the display device can display the currently measured lightThe illumination intensity is input into a mapping model, after the mapping model determines a three-dimensional lookup table (such as the three-dimensional lookup table 1) according to the illumination intensity, the three-dimensional lookup table 1 can be converted into an HSV color space from an RGB color space, and then H corresponding to the three-dimensional lookup table 1 is respectively determined through a fitting formula 0 、S 0 、V 0 Fitting with the 500Lux illumination intensity to obtain corresponding H, S, V under the 500Lux illumination intensity, converting HSV information obtained after fitting into an RGB color space, and converting the RGB color space into color coordinates corresponding to color nodes in a three-dimensional lookup table to obtain the target three-dimensional lookup table.
Alternatively, the target illumination intensity may be set according to actual requirements, without limitation, and for example, the target illumination intensity may be set to be generally 500Lux indoor illumination intensity.
In step S24, an image is displayed based on the target three-dimensional lookup table.
In some embodiments, the specific implementation of step S24 may include:
acquiring color information of the current display content; adjusting the color information of the display content through the target three-dimensional lookup table; and displaying the regulated display content.
Wherein the color information may be information in an RGB color space.
For example, the display device may detect the 3D LUT corresponding to the current display mode, detect the illumination intensity of the current ambient light by using the light sensor, input the illumination intensity of the current ambient light to the mapping model, obtain the target 3DLUT corresponding to the illumination intensity of the current ambient light output by the mapping model, and then detect whether the 3D LUT corresponding to the current display mode is consistent with the target 3D LUT, and if so, may directly adjust the color information of the display content by using the 3D LUT corresponding to the current display mode, and display the adjusted display content. If the color information of the display content is inconsistent, the 3D LUT corresponding to the current display mode and the target illumination intensity can be fitted to obtain a target 3D LUT, the color information of the display content is regulated through the target 3D LUT, and finally the regulated display content is displayed.
Therefore, in this embodiment, the corresponding HSV value under the target illumination intensity (e.g., 500 lux) is obtained by fitting the HSV value of the color under each illumination intensity with the target illumination intensity, because the V (brightness) dimension is easily affected by the illumination intensity of the ambient light in the HSV color space. Based on the measured 3D LUT data under each light intensity and the characteristic that the change of the color V in the HSV space is influenced by the light intensity, mapping the current illumination intensity to 500Lux, constructing a mapping model, and guaranteeing consistency of the mapped color H, S and V in the HSV space and the color V under 500Lux, so that consistent display effects of the user on the color of display content under different illumination intensities are guaranteed, for example, the target illumination intensity is 500Lux, if the current illumination intensity is 200Lux, the color display effect corresponding to 200Lux is converted to the display effect corresponding to 500Lux, and if the current illumination intensity is 100Lux, the color display effect corresponding to 100Lux is also converted to the display effect corresponding to 500Lux, thereby achieving consistent display effects and further improving user experience.
