Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In the following description, the terms "first" and "second" are used for descriptive purposes only and are not intended to indicate or imply relative importance. The following description provides embodiments of the present application, where different embodiments may be substituted or combined, and thus the present application is intended to include all possible combinations of the same and/or different embodiments described. Thus, if one embodiment includes feature A, B, C and another embodiment includes feature B, D, then this application should also be considered to include an embodiment that includes one or more of all other possible combinations of A, B, C, D, even though this embodiment may not be explicitly recited in text below.

With the development of the information age, no matter the electronic equipment is used more and more commonly in life or work, people in life need to operate the corresponding equipment when using the electronic equipment, so that the ambient illumination is necessary, and in an indoor complex work environment, workers need to process paper files and other matters besides reading graphic image information on a screen of the electronic equipment, so the ambient illumination is also necessary. For example, in the use process of a computer, the change of ambient light may cause visual fatigue, decrease of work efficiency, and the like when viewing the content on the computer screen, and it is necessary to adapt the user to the change of ambient light by manually adjusting the brightness of the screen so as to more efficiently read the content displayed on the screen, and the manual adjustment operation is cumbersome. At present, when people use electronic equipment, a display screen of the electronic equipment is a self-luminous device, visual fatigue is easily caused by too low ambient light according to visual characteristics of human eyes, and the reduction of screen display contrast is caused by the reflection phenomenon generated by the display screen due to too high ambient light, so that the identification degree of screen display content is reduced. Therefore, too high or too low ambient light intensity may increase reading and recognition difficulty, resulting in poor eyesight.

Based on this, an embodiment of the present application provides an ambient illumination intensity adjusting method, which includes obtaining reaction times of a test user for color matching images of different character colors under different background colors under preset different ambient illumination intensities, determining an ambient illumination intensity set with a shortest reaction time after the test user has sufficient visual adaptation for the different background colors and the different character colors among the preset different ambient illumination intensities based on the reaction times, determining a target ambient illumination intensity matched with a current background color and the current character color in the ambient illumination intensity set, and adjusting the current ambient illumination intensity received by a display device to the target ambient illumination intensity. According to the reaction time of the color matching images with different character colors under different background colors under different preset environment illumination intensities, the target environment illumination intensities of the color matching images with different background colors and different character colors are determined, the current environment illumination intensity is adjusted to the target environment illumination intensity according to the current background color and the current character color of the display device, the recognition degree of the display content in the screen of the display device is improved, the visual fatigue is relieved, the working efficiency is improved, and the like.

Fig. 1 is a schematic view of an architecture of an ambient light intensity adjusting system according to an embodiment of the present disclosure.

The system includes a terminal, which may include, but is not limited to, a personal computer, a desktop computer, a tablet computer, a palmtop computer, a smart phone, a smart interactive tablet, a laptop computer, a personal computer, a vehicle multimedia, etc. The method comprises the steps of obtaining the correct reaction time of at least one test user for each color matching image under preset different environment illumination intensities, if the correct reaction time is in a threshold range, calculating the average reaction time of each color matching image under the preset different environment illumination intensities based on the correct reaction time, taking the average reaction time as the reaction time of each color matching image under the preset different environment illumination intensities, determining the environment illumination intensity set with the shortest reaction time after the test user has sufficient visual adaptation for different background colors and different character colors from the preset different environment illumination intensities based on each reaction time, determining the environment illumination intensity corresponding to the shortest reaction time of each color matching pattern from the environment illumination intensity sets, and determining the environment illumination intensity corresponding to the shortest reaction time of each color matching pattern as a target environment illumination intensity set, and determining the target environment illumination intensity matched with the current background color and the current character color in the target environment illumination intensity set, and adjusting the current environment illumination intensity received by the display equipment to the target illumination intensity. According to the response time of at least one test user to the images with different character colors under different background colors under the preset different environment illumination intensities, determining an environment illumination intensity set of the response time of each color matching in the preset different environment illumination intensities, determining the environment illumination intensity matched with the current background color and the current character color in the environment illumination intensity set as the target environment illumination intensity, adjusting the current environment illumination intensity to the target illumination intensity, improving the identification degree of display contents in the display equipment, relieving visual fatigue, improving the working efficiency and the like.

Referring to fig. 2, a flow chart of an ambient light intensity adjusting method is provided in the present embodiment. As shown in fig. 2, the method for adjusting the ambient light intensity may include the following steps:

s101, obtaining the reaction time of a test user to each color matching image under preset different environment illumination intensities, wherein each color matching image is an image with different character colors under different background colors, and the reaction time is the time for the test user to react to each color matching image;

specifically, on the premise that the display screen is self-luminous, images with different background colors and different character colors are used as tested objects, the different background colors and the different character colors are subjected to color matching to form a plurality of color matching images, and the reaction time of at least one test user on each color matching image under the preset ambient illumination intensity is obtained.

The testing user is a person with normal vision or normal corrected vision, and the testing user can correctly judge the content in the color matching image.

For example, the background color may include, but is not limited to, black, blue, green, etc., the character color may include, but is not limited to, red, yellow, white, etc., and color-matching the background color with the character color may form 9 different color-matched images.

The preset ambient light intensity may include, but is not limited to, 0lx, 100lx, 300lx, 500lx, 700lx, 1000lx, and the like.

The reaction time may be the reaction time of at least one test user to the formed 9 color patterns under the preset ambient light intensities of 0lx, 100lx, 300lx, 500lx, 700lx and 1000 lx.

S102, determining a target environment illumination intensity set of each color matching image in the preset different environment illumination intensities based on each reaction time, wherein the environment illumination intensity set is the environment illumination intensity with the shortest reaction time after the test user has sufficient visual adaptation to different background colors and different character colors;

specifically, as in step S101, the reaction time of at least one test user for color matching images with different background colors and different character colors under different preset ambient light intensities is obtained, the ambient light intensity corresponding to the reaction time of each color matching image is used as an ambient light intensity set, and the ambient light intensity corresponding to the shortest reaction time of each color matching image is determined from the ambient light intensity set and used as a target ambient light intensity set.

The shortest reaction time is the reaction time corresponding to the environment illumination intensity with the highest watching comfort level of at least one test user on each color matching image under the preset different illumination intensities.

For example, the following table shows the reaction times of at least one test user for images with black background color and white character color under different illumination intensities.

TABLE 1 reaction time of images of white characters under black background at different illumination intensities

Illumination intensity (lx)	0	100	300	500	700	1000
							Reaction time（ms）	626	510	447	500	492	501

According to table 1, the reaction time of the image of the black background white character under different illumination intensities can be obtained, the ambient illumination intensity corresponding to the shortest reaction time of the image of the black background white character is 300lx, when the background of the display screen is black and the color of the character is white, the ambient illumination intensity of 300lx is the ambient illumination intensity most suitable for reading the display content on the display screen, and 300lx is taken as the target illumination intensity of the white character under the black background.

The reaction time in table 1 is an average reaction time of at least one test user for a white character image on a black background, for example, there are 4 test users, the background color is black, the character color is white, the ambient light intensity is 300lx, the reaction time of the 4 test users is divided into 450ms, 454ms, 420ms and 438ms, then the ambient light intensity is 300lx, and the reaction time of the black-white color image is (450 +454+436+ 448)/4 =447 ms.

S103, determining the target environment illumination intensity matched with the current background color and the current character color in the target environment illumination intensity set, and adjusting the current environment illumination intensity received by the display equipment to the target environment illumination intensity;

specifically, according to the target environment illumination intensity set corresponding to each color-matched image obtained in step S102, the target environment illumination intensity matched with the current background color and the character color is determined in the target environment illumination intensity set according to the display background color and the color matching of the character color in the current display screen, whether the current environment illumination intensity is consistent with the target environment illumination intensity is detected, and if the current environment illumination intensity received by the display device is inconsistent with the target illumination intensity, the current environment illumination intensity is adjusted to the target illumination intensity.

The current ambient light intensity may be detected by means including, but not limited to, measurement using a light meter, monitoring using a light sensor, and the like.

For example, the following table shows the target ambient light intensity sets corresponding to different color characters on a black background when the preset ambient light intensities are 0lx, 100lx, 300lx, 500lx, 700lx and 1000 lx.

TABLE 2 set of target ambient light intensities corresponding to different color characters under a black background

Character color	White colour	Red colour	Blue color	Green colour	Yellow colour
						Shortest reaction time (ms)	447	478	517	565	448
Target ambient light intensity (lx)	300	300	300	300	300

According to the table 2, the target environment illumination intensity sets corresponding to different character colors under the black background can be obtained, the target illumination intensities corresponding to different character colors under the black background are all 300lx, and the shortest reaction time of the white character and the yellow character under the black background is the smallest, so that when the background of the display screen is black, the color of the white character or the yellow character is most suitable for selection.

If the current display screen is a white character under a black background, and the current ambient light intensity measured by the illuminometer is 500lx, it is indicated that the current ambient light intensity is not the optimal ambient light intensity for the user to read the display content on the display screen, and the current ambient light intensity of 500lx needs to be adjusted to the target ambient light intensity of 300lx, so that the user can read the display content on the display screen more quickly and comfortably.

Referring to fig. 3, a flowchart of an ambient light intensity adjusting method is provided in an embodiment of the present application. As shown in fig. 3, the method for adjusting the ambient light intensity may include the following steps:

s201, under the same ambient light intensity, color matching images of different character colors under different background colors are sequentially displayed in preset display duration according to a set switching sequence; collecting the correct reaction time of at least one test user to each displayed color matching image;

specifically, the method comprises the steps of determining one environmental illumination intensity from preset different environmental illumination intensities, combining different background colors and different character colors under the condition that the environmental illumination is not changed to form a plurality of images with different character colors under different background colors, sequentially switching and displaying each color matching image on a display screen according to preset display duration and a set switching sequence, and collecting correct reaction time of at least one test user on each color matching image within preset display time by using psychological experiment software.

The switching order may include, but is not limited to, a background color invariant switching character color, a character color invariant switching background color, a background color, and a character color random non-repetitive switching, etc.

There are no duplicate color-matching images in each color-matching image during the switching process.

The preset display time period for each color scheme image may include, but is not limited to, 1000 milliseconds, 1500 milliseconds, 2000 milliseconds, 2500 milliseconds, and the like.

The psychological experiment software can be E-prime2.0, which is an experiment platform applied to computerized behavior research, can test the reaction time to millisecond precision, and can comprehensively collect experimental process data and preliminarily analyze experimental data. The method includes various aspects of program design and editing, program generation, program operation, experimental data collection and preliminary analysis, and has strong operability and integration.

The correct reaction time is the reaction time for testing the correct selection of each color matching image by the user under different environment illumination intensities.

For example, the following table shows color matching images of different character colors under different background colors sequentially displayed for a preset display duration under the same ambient light intensity, and collects the correct response time of a test user to each color matching image.

Table 3 shows the correct response time of each color matching image when the preset display duration is 1000 milliseconds and the ambient light intensity is 500lx, and the correct response time in table 3 is the correct response time for a test user to make a correct selection on each color matching image within 2000 milliseconds, which is collected by the psychological experiment software E-prime 2.0.

S202, sequentially switching the environmental illumination intensity according to the same mode to obtain the correct reaction time of the user on each color matching image under the preset different environmental illumination intensities;

specifically, after all the color matching images are sequentially switched and displayed, the next environment illumination intensity is determined from the preset different environment illumination intensities, and in the step S201, the color matching images are sequentially switched according to the preset display duration and the set switching sequence, and the correct reaction time of at least one test user on each color matching image in the preset display time is acquired by using the psychological experiment software.

Wherein the ambient light intensity remains unchanged after the ambient light intensity is determined.

For example, in step S201, the ambient light intensity is 500lx, the color matching images are sequentially switched according to the preset display time length while the ambient light intensity is kept unchanged at 500lx, the ambient light intensity is adjusted after the psychology software finishes collecting the correct reaction time of each test user on each color matching image, the color matching images are sequentially switched according to the preset display time length, and the psychology software collects the correct reaction time of each test user on each color matching image after the psychology software adjusts the light intensity.

The switching order of the color images after the adjustment of the ambient light intensity may be different from the switching order before the switching of the ambient light intensity, or may be the same as the switching order before the switching of the ambient light intensity.

The following table shows that when the ambient light intensity is 100lx, color matching images of different character colors under different background colors are sequentially displayed according to preset display duration, and correct response time of a test user to each color matching image is acquired.

Table 4 shows the correct response time of each color matching image when the preset display duration is 1000 milliseconds and the ambient light intensity is 100lx, and the correct response time in table 3 is the correct response time for a test user to make a correct selection on each color matching image within 2000 milliseconds, which is collected by the psychological experiment software E-prime 2.0.

S203, if the correct reaction time is within the threshold value range, determining the correct reaction time as the reaction time of the test user on each color matching pattern under different environment illumination intensities;

specifically, if the correct time of each color matching image acquired by the psychological experiment software for each test user under different environmental illumination intensities is within the threshold range, the correct reaction time of the test user detected by the psychological experiment software is determined as the reaction time of the test user under different environmental illumination intensities for each color matching image.

When the preset display duration is 1000 milliseconds, the threshold range may include, but is not limited to, 0-800 milliseconds, 0-850 milliseconds, 0-900 milliseconds, and the like.

When the preset display duration is 1500 milliseconds, the threshold range may include, but is not limited to, 0-1200 milliseconds, 0-1250 milliseconds, 0-1300 milliseconds, and the like.

When the preset display duration is 2000 milliseconds, the threshold range may include, but is not limited to, 0-1500 milliseconds, 0-1600 milliseconds, 0-1700 milliseconds, and the like.

As shown in table 3, the correct response time corresponding to each color matching image is preset for a test user when the ambient light intensity is 500lx, and the display duration is 1000 milliseconds, and if the threshold range is set to be 0-800 milliseconds, the correct response times are all within the threshold range, so that the correct response time in table 3 is determined to be between the responses of the test user to each color matching image when the ambient light intensity is 500 lx.

As shown in table 4, if the threshold range is set to be 0-800 ms, as can be seen from the correct response time collected in table 4, the correct response time corresponding to the blue background red character and the green background yellow character is outside the threshold range, and therefore, the correct response time corresponding to the blue background red character and the green background yellow character is eliminated, and the correct response time corresponding to the remaining color matching images is determined as the response time of the test user when the ambient illumination intensity is 100 lx.

The method comprises the steps of collecting correct reaction time of at least one test user for each color matching image according to preset display duration and a set switching sequence, sequentially switching the correct reaction time under different preset environment illumination intensities according to the set switching sequence, if the collected correct reaction time is within a threshold range, determining the correct reaction time as the reaction time of the corresponding test user for each color matching image under different environment illumination intensities, determining the environment illumination intensity corresponding to the shortest reaction time of each color matching image as a target environment illumination intensity set in the reaction time, determining the matched target illumination environment intensity according to background colors and character colors displayed on a current display screen, adjusting the current environment illumination intensity to the target illumination intensity, and improving the identification degree of display contents in the display screen so as to relieve visual fatigue and improve working efficiency.

specifically, according to the correct reaction time of the at least one test user for each color matching image under different ambient light intensities collected in step S301, if the collected correct reaction time is within the time threshold range, the average reaction time of each color matching image under each ambient light intensity by all test users is calculated, and the average reaction time is taken as the reaction time of the corresponding color matching image under the corresponding ambient light intensity.

The threshold range of the correct response time is set according to a preset display duration of each image on the display screen, and the preset display duration may include, but is not limited to, 1000 milliseconds, 1500 milliseconds, and 2000 milliseconds.

When the preset display duration is 1000 milliseconds, the threshold range of the correct reaction time may include, but is not limited to, 0-800 milliseconds, 0-850 milliseconds, 0-900 milliseconds, and the like.

When the preset display duration is 1500 milliseconds, the threshold range of the correct reaction time may include, but is not limited to, 0-1200 milliseconds, 0-1250 milliseconds, 0-1300 milliseconds, etc.

The ambient light intensity set includes the reaction time and the ambient light intensity corresponding to the reaction time.

The target ambient light intensity is the ambient light intensity at which the reading comfort of the user is highest for different background colors and different character colors among different ambient light intensities.

It should be noted that the correct reaction time includes a reaction time that is selected correctly by the user for each color matching image and exceeds a correct reaction time corresponding to the threshold range, and the reaction time is calculated according to the correct reaction time within the threshold range and does not include the correct reaction time exceeding the threshold range.

For example, the following table shows the response times of color-matching images of white characters on a black background under different preset ambient light intensities.

TABLE 6 reaction time of black background white characters under different ambient light intensities

Ambient light intensity (lx)	0	100	300	500	700	1000
							Reaction time (ms))	469	510	447	500	492	501

As shown in table 6, the target ambient light intensity of the white character under the black background is determined to be 300lx according to the shortest response time of 447 milliseconds and the ambient light intensity of 447 milliseconds in the table, where the light intensity corresponding to the response time in the table is determined to be the ambient light intensity set corresponding to the color matching image of the white character under the black background, and the ambient light intensity set corresponding to the color matching image of the white character under the black background is determined to be 447 milliseconds and 300 lx.

For example, white characters under a black background are displayed on a current display screen, the target environment illumination intensity corresponding to the white characters under the black background is determined to be 300lx from the target environment illumination intensity set, and when the current environment illumination intensity is detected to be 450lx, the power of an environment illumination source needs to be reduced, and the current environment illumination intensity 450lx is adjusted to be 300 lx.

The method for detecting the current ambient light intensity may include, but is not limited to, measuring by a light meter, monitoring by a light sensor, and the like.

It should be noted that, when it is detected that the current ambient illumination intensity is not the current background color and the target illumination ambient intensity corresponding to the current character color, the current ambient illumination intensity may be adjusted to the target illumination intensity by changing the distance between the display device and the ambient illumination source.

For example, yellow characters under a black background are displayed on a current display screen, a target illumination intensity corresponding to the yellow characters under the black background is determined to be 300lx from a target environment illumination intensity set, and if the current environment illumination intensity is detected to be 350lx, then the distance between the display device and the environment illumination source needs to be increased, and the display device or the environment illumination source can be moved to adjust the current environment illumination intensity to be 350 lx.
