Description
Technical Field
The invention relates to the technical field of mobile terminals, in particular to a screen brightness adjusting method, electronic equipment, a mobile terminal and a storage medium.
Background
Currently, a display screen of a mobile terminal includes: liquid Crystal Display (LCD) and Organic Light-Emitting Diode (OLED) Display, wherein the OLED Display realizes different gray scales corresponding to different screen brightness by adjusting Display parameter gamma (γ) voltages corresponding to different gray scales. The brightness of the existing screen is limited by luminescent materials, circuit design and the like, and can only achieve 430nit at most, while the requirement of the existing optical fingerprint on the brightness is higher and generally needs to achieve more than 600 nit. Therefore, the current main defects are as follows:
at present, when a High Brightness Mode (HBM) that a user opens an OLED screen of a mobile terminal is received, a circuit of a display module needs to be switched through a power-up and power-down sequence, so that the high brightness mode is opened, and at this time, the user is flashed in front of the eye; if the screen is maintained in the high brightness mode all the time, it is too dazzling for the user, resulting in poor user experience; and also increases the power consumption of the mobile terminal.
To solve this problem, in the related art, it is proposed to put the optical fingerprint area on the screen in a high brightness mode and the remaining area in a normal brightness mode. That is, a layer of mask is added on the rest area (i.e. non-fingerprint area) of the screen except the optical fingerprint area, and the gray scale of the display content is compressed by the mask to reduce the screen brightness, for example, a picture originally has 0-150 gray scale, but in order to reduce the brightness to 10nit, the gray scale may be compressed to 0-30 gray scale, so that the number information of gray scale that can be displayed is reduced, and the screen brightness of the non-fingerprint area is reduced. However, in the current technology, the screen brightness is reduced by compressing the gray scale information, if the required screen brightness is lower, the more the gray scale information is compressed, and when the gray scale information is compressed to a certain degree, the poor transition or the water ripple phenomenon is caused, which seriously affects the screen display effect.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a method for adjusting screen brightness according to an embodiment of the present invention; the method is applied to a mobile terminal of a full-screen, namely an Organic Light Emitting Diode (OLED) screen. The method may specifically comprise the steps of:
step 100: starting;
step 101: under the condition that a target image indicates an optical fingerprint identification scene, acquiring a first area and a second area of the target image to be displayed, wherein the first area is an optical fingerprint identification area, and the second area is an image area except the first area in the target image;
in the step, a current image to be displayed is obtained; when a user starts to use a mobile terminal (such as a mobile phone and the like), the system acquires a target image with a display on a screen of the mobile terminal, if the target image is a normally displayed target image, namely, no optical fingerprint identification scene exists in the target image, the system calculates gray scales (such as 0-X1) required for displaying all content details in the target image in a smooth transition mode, and outputs corresponding display contents with 0-X1 gray scales, namely, the contents of the target image are normally displayed.
The gray scale is the brightness variation between the brightest and darkest in the display screen, and is divided into several parts to facilitate the adjustment of the screen brightness. Each digital image is composed of a plurality of dots, also called pixels (pixels), each of which can usually represent a plurality of different colors, and is composed of three sub-pixels of red, green and blue (RGB). Each sub-pixel, the light source behind it, may exhibit a different brightness level. And the gray levels represent gradation levels of different brightness from the darkest to the brightest. The more the intermediate levels are, the more exquisite the picture effect can be presented.
If the target image comprises an optical fingerprint identification scene (namely under the condition that the target image indicates the optical fingerprint identification scene), acquiring a first area and a second area of the target image to be displayed, wherein the first area is an optical fingerprint identification area, and the second area is an image area except the first area in the target image; the first region is also called a highlight region, and the second region is also called a normal display region.
That is, the system determines whether the target image to be displayed includes an optical fingerprint recognition scene, and if so, marks a first region including the optical fingerprint recognition scene, that is, a highlight region, on the target image to be displayed, and other regions in the current image to be displayed are referred to as second regions, that is, normal display regions, that is, all regions except the highlight region in the image to be displayed. Wherein the optical fingerprinting scenario includes: an optical fingerprint payment scenario, an authentication scenario, an unlocking scenario, or the like, which is not limited to this, and other similar scenarios may also be included, and this embodiment is not limited to this.
Step 102: determining a first gray scale range of the first region and a second gray scale range of the second region;
in this step, the system calculates gray scale values and maximum gray scale values required by details of all contents in the target image to be displayed (the gray scale values are usually multiple, and the more the number of gray scales is, the finer and clearer the displayed picture is), for example, 0 to X1 gray scale values are required when the target image is normally displayed, and X1 represents the maximum gray scale value for normally displaying the target image; by the calculated gray-scale value, all contents in the target image can be displayed in a smooth transition. Then, taking the gray scale range formed by the calculated gray scale values as a second gray scale range of the image content to be drawn in the second area (namely the normal display area); and determining a gray scale range composed of gray scale values with values larger than the maximum gray scale value and smaller than or equal to 255 as a first gray scale range of the first area (namely, a highlight display area) for drawing the target image. That is, the normal display area uses the gray scale range of 0 to X1 (such as 0 to 250 gray scales) to draw the image content, and the highlight display area uses the gray scale range greater than X1 (such as 251 to 255 gray scales) to draw the image content, so as to dynamically adjust the gray scale ratio of different areas according to the content of the output image to be displayed, thereby covering different display pictures and scenes.
Step 103: displaying the target image, and adjusting the screen brightness of the first area and the second area according to the first gray scale range and the second gray scale range respectively in the process of displaying the target image;
in this step, the brightness level corresponding to each gray scale in the first gray scale range and the second gray scale range may be obtained from a preset correspondence between the gray scale and the brightness level. That is, the brightness level corresponding to the first gray scale range in which the first region (i.e., the highlight display region) draws the target image and the brightness level corresponding to the second gray scale range in which the second region (i.e., the normal display region) draws the target image are found from the corresponding relationship; and then, displaying the target image, and in the process of displaying the target image, adjusting the screen brightness of the first area (namely, a highlight display area) and the normal display area (namely, a second area) according to the searched brightness level corresponding to the first gray scale range and the brightness level corresponding to the second gray scale range. For example, the second gray scale range (i.e., 0-250) corresponding to the normal display area is defined, the highest gray scale 250 corresponds to the display brightness of 430nit (i.e., the highest brightness in the normal mode), and the 251-255 gray scales (i.e., the first gray scale range) correspond to different HBM brightness levels such as 480, 510, 540, 570, 600 nit.
Step 104: and (6) ending.
In the embodiment of the present invention, when a target image indicates an optical fingerprint recognition scene, a first region and a second region of the target image are obtained, where the first region is an optical fingerprint recognition region, and the second region is an image region of the target image except the first region, then a first grayscale range of the first region and a second grayscale range of the second region are determined, and finally, when the target image is displayed, screen brightness of the first region and the screen brightness of the second region are respectively adjusted according to the first grayscale range and the second grayscale range. That is to say, in the embodiment of the present invention, the gray scales of different areas are determined according to the content of the target image, and when the target image is displayed, the screen brightness is adjusted according to the brightness levels corresponding to the gray scale ranges corresponding to the different areas, so that the requirements for different brightness in different scenes in the same display screen are met. Meanwhile, for a highlight display area comprising an optical fingerprint identification scene, the integrity of data is reserved because the gray-scale value of the area is not reduced, so that the display effect of the image is improved.
Optionally, in another embodiment, on the basis of the above embodiment, before acquiring the first region and the second region of the target image, the method may further include: and establishing a corresponding relation between each gray scale value of the first area and the second area and the brightness level, wherein the lowest gray scale of the first area is higher than the highest gray scale of the second area. That is, the corresponding relation between each gray scale value and the brightness level of the normal display area and the highlight display area is established in advance; the lowest gray scale of the highlight display area is higher than the highest gray scale of the normal display area. Specifically, as shown in fig. 2, fig. 2 is a schematic diagram illustrating a corresponding relationship between gray scales and brightness levels according to an embodiment of the present invention.
As shown in fig. 2, the horizontal axis represents different gray levels, the vertical axis represents the luminance levels (which may also be referred to as luminance) corresponding to the gray levels, and the luminance level corresponding to a certain gray level X is defined, for example, the display luminance level corresponding to a gray level of 250 is defined as 430nit (i.e., the highest luminance in the normal mode). In the embodiment of the invention, the brightness level corresponding to the gray scale of 0-250 is defined as 0-430, and the corresponding area formed by the gray scale is called as the brightness level 201 of the normal display area; and defining that each gray scale of 251-255 corresponds to different HBM brightness levels of 480, 510, 540, 570, 600nit and the like, and the corresponding area formed by the gray scales is called as the brightness level 202 of the high-brightness display area. When the system outputs a target image, 251-255 gray scale contents can be output aiming at a special highlight display area such as a highlight fingerprint icon area, so that the requirement on brightness can be met, and a certain gray scale transition change can be realized; aiming at the normal display area without fingerprints, the maximum brightness of the normal display area meets the maximum brightness level 430nit of a normal mode, meanwhile, the display content in the gray scale range of 0-250 is reserved, and the quality and the effect of the displayed target image are good because the number of the gray scales is not compressed.
Referring to fig. 3, another flowchart of a method for adjusting screen brightness according to an embodiment of the present invention is shown, where the method specifically includes:
step 300 begins;
step 301: acquiring a target image to be displayed;
step 302: judging whether the target image comprises an optical fingerprint identification scene or not, and if so, executing a step 303; otherwise, the feedback continues to step 302;
in the step, the system judges whether the content of the target image to be displayed has an optical fingerprint identification scene, wherein the optical fingerprint identification scene can comprise an optical fingerprint payment scene or an authentication scene and the like; if so, go to step 303; if not, go to step 308: i.e. the content of the second area image is normally displayed.
Step 303: acquiring a first area and a second area of the target image, wherein the first area is an optical fingerprint identification area, and the second area is an image area except the first area in the target image;
the first region in this embodiment is illustrated as a highlight display region and the second region is illustrated as a normal display region. Marking a highlight display area and a normal display area comprising the optical fingerprint identification scene on the target image to be displayed, wherein the normal display area is all areas except the highlight display area in the target image to be displayed;
in this step, the system marks different display areas on the target image to be displayed, such as a highlight display area including the optical fingerprint recognition scene as a1, a normal display area as a2, and so on.
The specific process of this step refers to step 101, which is described in detail above and will not be described herein again.
Step 304: determining a first gray scale range of the first region and a second gray scale range of the second region;
the step is the same as step 102, and is described in detail above, and will not be described herein again.
Step 305: displaying the target image, and adjusting the screen brightness of the first area and the second area according to the first gray scale range and the second gray scale range respectively in the process of displaying the target image;
for convenience of understanding, please refer to fig. 4 specifically, wherein fig. 4 is a schematic diagram of a display screen including a first area and a second area according to an embodiment of the present invention.
In this embodiment, fig. 4 takes as an example that a target image a to be displayed is output, where the target image a includes: when the system outputs the target image a, the system calculates that the target image needs 0 to X1 gray scales to smoothly and transitionally display all the details in the target image, and then allocates the gray scale value in the range of 0 to X1 to the normal display area a2, that is, the normal display area a2 uses the gray scale value in the range of 0 to X1 to perform drawing. For the highlight region a1, the system assigns the X1+1 gray scale values to 255 gray scale values to the highlight region a1, i.e., the X1+1 gray scale values to 255 gray scale values are used for drawing the target image in the highlight region a 1. Then, the brightness level corresponding to each gray scale value in the gray scale range of the highlight display area and the normal display area is found from the preset corresponding relation; and then, adjusting the screen brightness of the highlight display area and the normal display area according to the searched brightness level.
In summary, in this embodiment, the system can dynamically adjust the gray scale ratios of different areas according to the content of the target image to be output and displayed, so as to cover different display pictures and scenes in the same display screen, so that the display effects of the highlight area a1 and the normal display area a2 are smooth, the problem of poor transition or water ripple does not exist, and the requirements of different areas for different brightnesses are met.
Step 306: after the screen brightness is adjusted, carrying out optical fingerprint identification on the image of the first area;
in the step, optical fingerprint identification is carried out on the image of the highlight display area; the process of performing optical fingerprint identification in the highlight area is well known to those skilled in the art, and will not be described herein.
Step 307: and after the optical fingerprint identification, drawing the image content of the first area according to the second gray scale range of the second area.
In this step, after the optical fingerprint recognition, the contents of the optical fingerprint recognition area are restored to the mode of the normal display area. That is, since the high luminance gradation HBM mode is not required to be used again in the highlight display region a1, the gray scale used in the highlight display region a1 needs to be restored to the gray scale used in the normal mode, that is, the same gray scale as that used in the normal display region a 2.
Step 309: and (6) ending.
In the embodiment of the invention, the gray scales of different areas are determined according to the content in the target image to be displayed, and the brightness of the screen is adjusted according to the brightness levels corresponding to the gray scale ranges of the different areas when the target image is displayed, so that the brightness requirements of the different areas in the same display screen are realized, the requirements of different scenes on different brightness are met, the problem of screen flickering caused by circuit switching is avoided by adopting the scheme of the embodiment, and the experience of a user in using optical fingerprint identification is improved. The number of gray scales of the highlight display area is not reduced, so that the integrity of data is kept, and the display effect of the image is improved. Furthermore, after the optical fingerprint identification, the highlight display area can be restored to the brightness mode of the normal display area, and the experience of the optical fingerprint identification scene and the image display effect are improved.
Referring to fig. 5, a flowchart of a method for adjusting screen brightness according to an embodiment of the present invention is shown, where the method includes:
step 500: starting;
step 501: acquiring a target image to be displayed;
step 502: judging whether the target image comprises an optical fingerprint identification scene, if so, executing step 503; otherwise, executing step 510, namely normally displaying the target image of the second area;
step 503: acquiring a first area and a second area of the target image, wherein the first area is an optical fingerprint identification area, and the second area is an image area except the first area in the target image;
step 504: determining a first gray scale range of the first region and a second gray scale range of the second region;
step 505: displaying the target image, and adjusting the screen brightness of the first area and the second area according to the first gray scale range and the second gray scale range respectively in the process of displaying the target image;
in this embodiment, the implementation processes of steps 501 to 505 are the same as those of steps 301 to 305, and are described in detail above, and are not described herein again.
Step 506: judging whether an adjusting instruction input by a user is received; if so, go to step 508 and step 509; otherwise, go to step 507;
in this step, the need for detail transition and brightness perception is different for different users, so that the user may need the brightness of the highlight area (such as the fingerprint area) to be lower or higher, or the detail transition of the normal display area to be lower or higher. If not, go to step 507; if so, steps 508 and 509 are performed.
Step 507: in response to the first input, adjusting a brightness level corresponding to at least one gray-scale value of the first area and/or the second area; thereafter, step 508 and step 509 are performed;
in this step, if the user thinks that the brightness of the highlight area (for example, the fingerprint display area) is too high and is a bit dazzling, the brightness ratio of the X +1 to 255 grayscales of the highlight area can be adjusted downward, for example, X is 250 grayscales, the brightness corresponding to the 251 to 255 grayscales default by the system is 480, 510, 540, 570, 600nit, respectively, and the user can adjust the brightness to 440, 470, 500, 530, 560 nit.
If the user considers that the transition effect of the normal picture in the normal display area is not good enough and more gray scales need to be allocated, the threshold of X can also be adaptively improved, for example, X is 230 gray scale, and the user can actively adjust the gray scale to 250 gray scale to satisfy the better transition effect. After this, the process proceeds to step 508 and step 509.
Step 508: after the screen brightness is adjusted, carrying out optical fingerprint identification on the image of the first area;
step 509: and after the optical fingerprint identification is finished, drawing the image content of the first area according to the second gray scale range of the second area.
The steps 508 and 509 are the same as the steps 306 and 307, and are described in detail above, and are not described herein again.
Step 511: and (6) ending.
In the embodiment of the invention, the content of an image to be displayed is acquired firstly, if the content comprises an optical fingerprint identification scene, a highlight display area and a normal display area comprising the optical fingerprint identification scene are marked on the image to be displayed, then the gray scales of the highlight display area and the normal display area are determined, and finally, when the content of the image to be displayed is displayed, the screen brightness of the highlight display area and the normal display area is adjusted according to the determined gray scales. And when the screen brightness is judged not to meet the use requirement, adjusting the gray scales of the highlight display area and the normal display area according to the requirement and the brightness levels corresponding to the gray scales, namely, in the embodiment of the invention, the gray scales of different areas are determined according to the content in the image to be displayed, and when the image is displayed, the screen brightness is adjusted according to the brightness levels of the gray scales corresponding to the different areas, so that the requirements of different users on different brightness in a scene in the same display screen are met aiming at the brightness requirements of the different areas, the problem of screen glare caused by circuit switching is avoided by adopting the scheme of the embodiment, and the experience of the users in using optical fingerprint identification is improved. Because the gray scale of the highlight display area is not reduced, the integrity of data is reserved, and the display effect of the image is improved. Furthermore, the user can provide more services for the effect according to the requirement of the user on the display effect, and the experience of the user is enriched. Furthermore, after optical fingerprint identification, the highlight display area can be restored to the brightness mode of the normal display area, so that the experience of optical fingerprint identification and payment is optimized, and the image display effect is optimized.
