Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
The inventor of the present application has found that vertigo felt by a user during using an electronic device, such as a head-mounted electronic device, has a relationship with the quality of a picture displayed by the head-mounted electronic device. When the displayed picture quality is high, the head-mounted electronic device needs to spend more time processing images, so that the displayed images cannot be updated timely along with the movements of the head of the user, such as rotation, and the like, and vertigo is brought to the user. Therefore, the embodiment of the invention provides a display adjusting method, an electronic device and an apparatus, which are used for adjusting the picture quality displayed in a display area.
As shown in fig. 1, an embodiment of the present invention provides a display adjustment method, which may include:
s100, acquiring a first instruction, wherein the first instruction is used for instructing adjustment of the quality and the fluency of the picture displayed in a display area, for example, the quality and the fluency of the picture projected on a display screen of the head-mounted electronic device or the display area of the head-mounted electronic device are adjusted;
the first instruction may be issued by a user through an input device in the electronic device, or generated by the electronic device itself, for example: the first instruction is generated periodically. Taking the head-mounted electronic device as an example, the input device in the head-mounted electronic device may be a physical key, a physical knob, a touch screen, a voice input device, or the like. For example: the head-mounted electronic equipment is provided with the solid knob, and a user adjusts the picture quality of the head-mounted electronic equipment by rotating the solid knob, wherein the adjustment degree and the adjustment direction of the picture quality can be respectively related to the rotation angle and the rotation direction of the knob by the user. For example: the user rotates the entity knob clockwise, the picture quality is improved, and the more the user rotates, the more the picture quality is improved; accordingly, the picture quality is degraded as the user rotates the physical button counterclockwise, and the more the user rotates, the more the picture quality is degraded.
When the input device is an entity button, the user can press the entity button, so that a first instruction is issued, and the invention executes the subsequent steps according to the first instruction.
When the input device is a touch screen, an interface displayed by the touch screen may be displayed on a main display screen (display area) of the head-mounted electronic device. It is understood that the main display is disposed on the inner side of the head-mounted electronic device, and the user can see the image displayed on the main display when wearing the head-mounted electronic device with the eyes facing the main display. And the touch screen can be arranged on the outer side of the head-mounted electronic equipment so as to facilitate the operation of a user. Specifically, an image acquisition device is further arranged on the outer side of the head-mounted electronic device to acquire the position and the action of the finger of the user on the touch screen. Therefore, the head-mounted electronic equipment can execute corresponding operation according to the position and the action of the finger on the touch screen, which are acquired by the image acquisition equipment, and send a first instruction to the head-mounted electronic equipment when the executed corresponding operation is the preset operation for generating the first instruction. In order to facilitate the user to see the operation of the user on the touch screen, the virtual finger can be displayed on the interface of the touch screen displayed on the main display screen according to the position and the action of the finger on the touch screen acquired by the image acquisition equipment, and the position and the action of the virtual finger on the interface of the touch screen displayed on the main display screen are consistent with the position and the action of the actual finger of the user on the interface of the touch screen.
When the input device is a voice input device, the head-mounted electronic device can perform voice recognition on a voice signal acquired by the voice input device, so that a first instruction sent by a user is acquired.
In step S100, the first command may be only a start command of the picture quality adjusting function, or may be an adjusting command including an adjusting parameter (e.g., how much to adjust) for adjusting the picture quality.
As will be understood by those skilled in the art, display fluency and picture quality are two related picture parameters, and for a head-mounted electronic device whose hardware (e.g., a central processing unit CPU, a graphics processing unit GPU) does not change, the higher the picture quality of the display, the lower the display fluency; accordingly, the lower the picture quality of the display, the higher the fluency of the display. Therefore, the display fluency can be adjusted by adjusting the picture quality.
S200, acquiring at least one adjusting parameter for adjusting the picture quality and the display fluency;
the adjustment parameter may be directly obtained from the first instruction, or may be automatically generated according to an image displayed in the display area, for example: when the display delay time of the image displayed by the head-mounted electronic equipment is determined to be too large according to the image displayed by the head-mounted electronic equipment, an adjusting parameter for reducing the delay time is generated. The adjustment parameter may be a display delay time or a resolution. Optionally, the display fluency is indicated by the display delay time, and the larger the display delay time is, the lower the display fluency is; the smaller the display delay time, the higher the display fluency. Optionally, the present invention indicates the picture quality by the resolution, and the higher the resolution is, the higher the picture quality is; the lower the resolution, the lower the picture quality.
Since the display delay time and the display fluency have the above relationship, the first command may only have the corresponding parameter of the display fluency, and step S200 of the present invention may determine the display delay time corresponding to the parameter according to the corresponding parameter of the display fluency. Similarly, the first command may only have a corresponding parameter of the picture quality, and step S200 of the present invention may determine the resolution corresponding to the parameter according to the corresponding parameter of the picture quality.
Of course, the adjustment parameter obtained in step S200 may also be a parameter of picture quality or a parameter of display fluency.
Step S200 may specifically include: and acquiring the display delay time or resolution which is carried in the first instruction and is used for adjusting the picture quality and the display fluency.
Wherein, adjusting the parameter may include: display latency and/or resolution. Of course, the adjustment parameter acquired in step S200 may be a plurality of display delay times and/or a plurality of resolutions acquired at different acquisition timings. For example: the display delay time and the resolution are acquired at 2 nd, 3 rd and 4 th seconds, respectively, and then the adjustment of the picture quality is performed based on these six acquired data.
And S300, dynamically adjusting the picture quality displayed in the display area according to the acquired adjustment parameters.
When the number of the obtained adjustment parameters is only 1, the picture quality can be dynamically adjusted directly according to the size relationship between the adjustment parameters and the corresponding preset parameters.
For example: when the adjustment parameter is the display delay time, step S300 may specifically include:
when the display delay time is greater than a preset delay time, reducing the resolution of the picture displayed in the display area;
and when the display delay time is not greater than the preset delay time, maintaining the resolution of the picture displayed in the display area.
Specifically, when the resolution of the picture displayed in the display area is reduced, the resolution may be reduced by one step at a time, for example: resolution of 2560 x 1600 was reduced to: 2560*1440. Of course, multiple resolution steps may be reduced, and the invention is not limited thereto. After the resolution is reduced, the invention can automatically or again acquire the first instruction and then execute steps S200 and S300 again to control the display area, especially for the head-mounted electronic device, so that the displayed picture quality reaches the degree that a user can see a clearer image without feeling dizzy.
Wherein, the delay time at which most users do not feel vertigo can be determined as the preset delay time by collecting the use feelings of a plurality of users under different delay times. Of course, a delay time range can also be determined where most users do not feel vertigo. Thus, when the adjustment parameter is the display delay time, step S300 may specifically include:
when the display delay time is out of a preset delay time range, reducing the resolution of the picture displayed in the display area;
and when the display delay time is within a preset delay time range, maintaining the resolution of the picture displayed in the display area.
When the number of the obtained adjustment parameters is only a plurality, the obtained adjustment parameters may be processed (e.g., averaged), and then the quality of the picture may be dynamically adjusted according to the size relationship between the processing result and the corresponding preset parameter. The process of dynamically adjusting the quality of the picture according to the magnitude relationship between the processing result and the corresponding preset parameter is similar to the principle of directly dynamically adjusting the quality of the picture according to the magnitude relationship between the adjustment parameter and the corresponding preset parameter, and is not described in detail.
Of course, the adjustment parameter may also be resolution, in this case, step S300 may specifically include:
when the resolution is larger than the preset resolution, reducing the resolution of the picture displayed in the display area;
and when the resolution is not greater than the preset resolution, maintaining the resolution of the picture displayed in the display area.
In practical applications, the steps S200 and S300 of the present invention may be executed multiple times to dynamically adjust the quality of the picture displayed by the display area according to the display parameters of the display area at different times. The display parameter may be a display delay time or a resolution.
The display adjusting method provided by the invention can obtain at least one adjusting parameter, and dynamically adjust the picture quality displayed in the display area according to the obtained adjusting parameter, thereby effectively reducing the time required for processing the image, and enabling the image displayed in the display area to be updated in time.
As shown in fig. 2, in another display adjustment method provided in the embodiment of the present invention, step S200 in the embodiment shown in fig. 1 may specifically include:
s210, receiving a detection instruction, drawing an image by using a preset image element, and recording the starting time for starting drawing the image;
the image elements may be color tones, pattern shapes, and the like.
Wherein the start time of starting to draw the image may be a time when the CPU starts to process the image.
Specifically, step S210 may replace a frame of image that should be originally drawn and displayed in the display area with an image drawn by a predetermined image element. Thus, the image rendered with the predetermined image elements is inserted into the image to be displayed in the display area. And the replaced image is not drawn and displayed.
S220, detecting the image displayed in the display area through a detection unit;
the detection unit can be a light sensor or an image acquisition device; alternatively, the detection unit may be disposed in front of a main display screen of an electronic device, such as a head-mounted electronic device, so as to sufficiently acquire information of an image displayed on the main display screen.
Specifically, when the image element is a color tone (e.g., red, green, blue, and white), the detecting unit is a light sensor, and the light sensor can rapidly identify the color tone of the image displayed on the main display screen. In order to improve the recognition efficiency and accuracy of the light sensor, only a single-tone image can be displayed on the main display screen, such as: all display areas of the main display screen are displayed in white.
The step S210 of drawing the image with the predetermined image elements may include: the image is rendered in at least one tone detectable by the detection unit.
Since the light sensor is more sensitive to the four hues of red, green, blue, and white, the hue of the drawn image is preferably at least one of the four hues, and more preferably, only one of the four hues.
Of course, the light sensor can also detect and identify other tones, so the invention does not limit the specific tone of the drawn image, and only needs the detection unit to detect.
Further, the drawing the image in at least one tone detectable by the detection unit may include:
randomly selecting one tone from at least one tone detectable by the detection unit to draw the image;
or
After receiving a detection instruction, acquiring a main tone of a current picture to be drawn;
selecting a hue to render the image based on the dominant hue and at least one hue detectable by the detection unit.
It can be understood that the image with a certain color tone drawn by the present invention is greatly different from the image originally displayed in the display area, and therefore, inserting the image with a certain color tone drawn by the present invention into the displayed multi-frame image will bring a sharp feeling to the user. In order to reduce discomfort of a user as much as possible, the present invention may first acquire a dominant hue of a picture to be drawn in a display region (i.e., a current picture to be drawn) before drawing an image of a certain hue, and select a hue close to the color of the dominant hue from among hues detectable by the detection unit to perform drawing of an image having a single hue. Because the color tone of the frame image is close to the color tone of the main color tone of the current picture to be drawn, the frame image with the single color tone drawn by the invention has higher color tone similarity with the image displayed before, and the discomfort of the user is reduced.
When the image element is in a pattern shape, the detection unit is an image acquisition device; the image acquisition equipment can rapidly identify the pattern shape of the image displayed by the main display screen. In order to improve the recognition efficiency and accuracy of the image acquisition device, only simple pattern shapes can be displayed on the main display screen, such as: a circular pattern.
S230, when the detection unit detects that the image element of the image displayed in the display area is the preset image element, recording a first time when the detection unit detects that the image element is the image of the preset image element;
s240, obtaining the display delay time for adjusting the picture quality and the display fluency based on the starting time and the first time.
Specifically, the time interval between the start time and the first time may be directly determined as the display delay time. In practical applications, since it takes a certain time for the detecting unit to detect that the image element of the image displayed in the display area is the predetermined image element after the image is displayed in the display area, the invention may further set a time correction factor for a time interval between the start time and the first time to minimize or even eliminate an influence of the time taken for the detecting unit to detect on the time interval, and determine a product of the time interval and the time correction factor as the display delay time.
Wherein, the time correction factor is <1, optionally, the value range of the time correction factor is: 0.7 to 0.9. Of course, when the detecting units are different devices, the time correction factors may also be different, for example: the time correction factor for a high performance detector unit may be large. The following steps are repeated: when the detection unit is an image acquisition device, the time correction factor is smaller than that when the detection unit is a light ray collector. This is because the light collector only needs to collect the hue, and needs less processing and takes less time.
For ease of understanding, the display delay time is explained below with reference to fig. 3:
as shown in fig. 3, before the display area displays the current frame of image, the CPU and the GPU in the electronic device need to respectively complete processing of the frame of image data, and then the display area can display the current frame of image. It is understood that the electronic device to which the embodiments of the present invention are applied may also have no GPU, and the GPU may be performed by the CPU. Specifically, the CPU may be responsible for sending image data to the GPU, which is responsible for rendering the image. As shown in fig. 3, the display delay time is a time interval from the time when the CPU starts processing the image data to the time when the image is displayed in the display area. Wherein, the time when the CPU starts to process the image data is the start time, and the time when the image is displayed in the display area is the first time.
In the process of creating the present invention, the inventor of the present application further finds that the image jamming in the prior art also further aggravates the vertigo feeling brought to the user, and particularly, for the head-mounted electronic device, the vertigo feeling of the user using the head-mounted electronic device is aggravated. After the research, the inventor of the present application finds that the reason for the problem is: the picture displayed in the display area has high quality, so that the display delay time is too long and exceeds the display time of one image frame.
Taking the head-mounted electronic device as an example, assuming that the head-mounted electronic device displays 24 frames of images per second and each frame of image displays 1/24 seconds in a normal case, a process of processing and displaying each frame of image by the head-mounted electronic device in a normal case where no jamming occurs will be described below by taking fig. 4 as an example. As shown in fig. 4, the processing of the image of the second frame by the CPU and the GPU is completed in the display process (1/24 seconds) of the image of the first frame, and at this time, the image of the second frame may be displayed in the head-mounted electronic device after the display of the image of the first frame is completed. The situation of the other frame images is similar and is not described again.
The following describes a process of processing and displaying each frame image by the head-mounted electronic device in an abnormal situation where a jam occurs, by taking fig. 5 as an example. As shown in fig. 5, the processing procedure of the second frame image by the CPU and the GPU cannot be completed in the displaying procedure (1/24 seconds) of the first frame image, and at this time, the first frame image is only displayed 1/24, and the second frame image cannot be displayed in the head-mounted electronic device until the second frame image is processed. The image is displayed for a prolonged period of time in the first frame of image, and therefore image sticking is caused.
The display adjusting method provided by the embodiment of the invention can also solve the problem of the image sticking because the picture quality of the displayed image is higher due to the sticking, and simultaneously reduces the dizzy feeling brought to the user.
While, for purposes of simplicity of explanation, the foregoing method embodiments have been described as a series of acts or combination of acts, it will be appreciated by those skilled in the art that the present invention is not limited by the illustrated ordering of acts, as some steps may occur in other orders or concurrently with other steps in accordance with the invention. Further, those skilled in the art should also appreciate that the embodiments described in the specification are preferred embodiments and that the acts and modules referred to are not necessarily required by the invention.

The first instruction may be issued by a user through an input device in the electronic device, or generated by the electronic device itself, for example: the first instruction is generated periodically.

For example: the head-mounted electronic equipment is provided with the solid knob, and a user adjusts the picture quality of the head-mounted electronic equipment by rotating the solid knob, wherein the adjustment degree and the adjustment direction of the picture quality can be respectively related to the rotation angle and the rotation direction of the knob by the user. For example: the user rotates the entity knob clockwise, the picture quality is improved, and the more the user rotates, the more the picture quality is improved; accordingly, the picture quality is degraded as the user rotates the physical button counterclockwise, and the more the user rotates, the more the picture quality is degraded.
