Description

Technical Field

[0001] The present application relates to the technical field of controlling picture filtering functions, and in particular to an anti-shake display method, device, head-mounted display device and storage medium. Background Art

[0002] A head-mounted display device is an electronic display device that is directly worn on the user's head. When the head-mounted display device moves with the user's head, the angular velocity of the head-mounted display device can be collected to adjust the picture frame, so that the display picture of the head-mounted display device changes with the user's movement. However, when the user is in a stationary state, there will also be slight jitter, and the angular velocity caused by the slight jitter will cause an offset between the upper and lower picture frames. At this time, the display picture of the head-mounted display device will jitter due to the offset between the upper and lower picture frames, resulting in an unstable picture and causing picture drift. The existing related technology can set an offset threshold. When the offset between the two picture frames generated by the jitter is less than or equal to the offset threshold, it will be filtered out through the picture filtering function. However, when the amplitude of the jitter is large, the offset between the two picture frames generated by the jitter is greater than the offset threshold, the picture frame corresponding to the jitter will not be filtered, which will cause the display picture of the head-mounted display device to have obvious picture jitter and unstable display problems, affecting the user's viewing experience. Therefore, the anti-shake display method of the related technology has the technical defect of poor filtering effect. Summary of the invention

[0024] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0025] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present application.

In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. The singular forms of "a", "said" and "the" used in the present application and the appended claims are also intended to include the majority form, unless the context clearly indicates other meanings. The words "if" / "if" used herein can be interpreted as "at the time of" or "when" or "in response to determination".

[0027] In addition, in the description of this application, unless otherwise specified, "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0028] In order to better understand the technical solution of the present application, the relevant application scenarios of the present application are introduced below.

[0029] The application scenarios of this application include head-mounted display devices, which are electronic devices that send optical signals to the user's eyes by being worn on the user's head to display images to the user's eyes. Common head-mounted display devices include AR glasses, VR glasses, and MR glasses.

[0030] When the head-mounted display device moves with the user's head, the angular velocity of the head-mounted display device is collected to adjust the picture frame, so that the upper and lower picture frames in the display of the head-mounted display device are offset to show the effect that the display changes with the user's movement. However, the angular velocity caused by a small shake will cause the upper and lower picture frames to offset. At this time, the display of the head-mounted display device will shake due to the offset of the upper and lower picture frames, resulting in unstable picture.

[0031] The related technology can set an offset threshold. When the offset between two picture frames caused by the jitter is less than or equal to the offset threshold, it will be filtered out by the picture filtering function. However, when the amplitude of the jitter is large, the offset between the two picture frames caused by the jitter is greater than the offset threshold, the picture frame corresponding to the jitter will not be filtered by the picture filtering function. Therefore, the related technology has a technical defect of poor filtering effect.

[0032] For example, when the offset threshold is set to 0.05 pixels, the picture filtering function can be activated to filter out the picture frames whose offset from the previous picture frame is less than or equal to 0.05 pixels. However, for some picture frames generated by signal glitches or large amplitude jitters, their offset from the previous picture frame will be greater than 0.05 pixels. Therefore, these picture frames cannot be filtered out by the picture filtering function of the related technology. When the head-mounted display device displays these picture frames, there will be obvious picture jitter and unstable display, affecting the user's viewing experience.

[0033] The head-mounted display device of the application scenario of the present application has a picture filtering function. According to the offset of each picture frame in the second time relative to the previous picture frame of each picture frame, it is judged whether offset display is required when the offset is greater than a preset first offset threshold. This can improve the stability of the picture display and improve the user's viewing experience.

[0034] See also Figure 1 , which is an anti-shake display method of an embodiment of the present application, applied to a head-mounted display device, the method comprising:

[0035] S10: Determine the offset of the current head mounted display device; the offset represents the offset degree of the head mounted display device at the first time.

[0036] The first time can be set by the user, or the time interval between two picture frames can be directly used as the first time, for example, the time interval between the upper and lower picture frames is used as the first time, and the offset represents the offset degree between the upper and lower picture frames.

[0037] Specifically, S1: a step of determining an offset of a current head mounted display device, comprising:

[0038] S11: Acquire the time interval between two adjacent picture frames and the corresponding angular velocity.

[0039] S12: Obtain an offset according to the angular velocity and the time interval.

[0040] The offset is the product of the angular velocity and the time interval. The angular velocity can be obtained by an IMU (inertial measurement unit) set in the head-mounted display device. Specifically, the angular velocity is affected by the speed and / or acceleration of the head-mounted display device when it is active. According to the time interval between the adjacent upper and lower picture frames and the angular velocity of the head-mounted display device, the corresponding offset can be accurately calculated.

[0041] S20: If the offset is greater than or equal to a preset first offset threshold, and the motion state of the current head mounted display device satisfies that the offset within the second time is greater than the preset first offset threshold, then the display content is controlled to be displayed offset along with the offset of the head mounted display device.

[0042] Among them, step S20 is executed when the picture filtering function of the head-mounted display device is in the startup state. The startup state refers to a period of time from starting the picture filtering function to turning off the picture filtering function. When the picture filtering function is in the startup state, the head-mounted display device can filter the picture frames that are less than the first offset threshold to control the display content to remain unchanged in the position of the head-mounted display device, thereby improving the stability of the display picture of the head-mounted display device.

[0043] Among them, the first offset threshold is used to determine whether the picture frame is caused by slight jitter when the picture filtering function is in the activated state. If the offset is less than the first offset threshold, it means that the corresponding picture frame to be judged is caused by slight jitter and should be filtered; if the first offset is greater than or equal to the offset threshold, it means that the corresponding picture frame to be judged is caused by large jitter or is generated by the user's active head-mounted display device, and it is necessary to combine the offsets of each picture frame within the second time before the picture frame to determine whether to retain or filter the picture frame to be judged. If the picture frame to be judged is retained, the display content is controlled to be displayed with an offset according to the offset of the head-mounted display device.

[0044] Offset display indicates that the screen filtering function is turned off. At this time, the screen filtering function will not filter the screen according to the offset size, so as to keep controlling the display content for offset display with the offset of the head-mounted display device until the preset unit duration of the offset display is reached. Then, it is determined whether to continue the offset display according to the unit duration, or to stop the offset display and restart the screen filtering function.

[0045] The second time refers to a time period before the picture frame to be judged, and the offset in the second time includes multiple offsets of the head-mounted display device in the time period. When the first time corresponding to the offset is the time interval between the upper and lower picture frames, the offset in the second time includes the offsets of all the upper and lower picture frames of the head-mounted display device in the time period. For example, the second time includes three picture frames, and the offset in the second time includes the offset of the second picture frame relative to the first picture frame and the offset of the third picture frame relative to the second picture frame. Specifically, the second time is set by the user, and its unit of measurement is seconds, which can be set to 0.1 seconds, 0.15 seconds, 0.2 seconds, 0.25 seconds, 0.3 seconds, 0.35 seconds, etc. For example, when the second time is set to 0.2 seconds, the offset of each picture frame relative to the previous picture frame of each picture frame within 0.2 seconds calculated forward from the time node of the picture frame to be judged is compared with the first offset threshold, and the comparison result is the motion state of the wearable display device in the second time.

[0046] S30: If the offset is less than a preset first offset threshold, or the offset is greater than the preset first offset threshold, but the duration of the continuous offset greater than the preset first offset threshold is shorter than a second time, the position of the displayed content on the head-mounted display device is controlled to remain unchanged.

[0047] Among them, the second time is longer than the first time.

[0048] Among them, if the offset is greater than a preset first offset threshold, but the duration of the continuous offset greater than the preset first offset threshold is shorter than the second time, it means that the picture frame to be judged corresponding to the offset and the picture frames within the previous second time are not picture frames generated by the user's active head-mounted display device. The picture frame to be judged is generated by a large jitter. Although it cannot be filtered through the first offset threshold, it is also a picture frame that needs to be filtered. Therefore, deletion filtering processing is required to control the position of the display content on the head-mounted display device to remain unchanged, thereby improving the stability of the picture frames displayed by the head-mounted display device.

[0049] Compared with the related art, in the present application, when the offset of the current head-mounted display device is greater than a preset first offset threshold, and the motion state of the current head-mounted display device satisfies that the offset within the second time is greater than the preset first offset threshold, the display content is controlled to be displayed offset with the offset of the head-mounted display device; when the offset is less than the preset first offset threshold, or the offset is greater than the preset first offset threshold, but the duration of the continuous offset greater than the preset first offset threshold is shorter than the second time, the position of the display content on the head-mounted display device is controlled to remain unchanged; in combination with the relationship between the offset of the head-mounted display device within the second time and the first offset threshold, it is determined whether to perform offset display, thereby preventing the offset display of picture frames with excessive jitter amplitude, which may cause obvious picture jitter and unstable display, thereby improving the accuracy of determining whether to perform offset display, increasing the stability of picture display, and improving the user's viewing experience.

[0050] See also Figure 2 , in a feasible embodiment, further comprising:

[0051] S21: During the offset display process, detect multiple offsets of the head mounted display device at a third time; wherein the third time is longer than the first time.

[0052] The third time is set by the user, and the third time can use the same time value as the second time. The multiple offsets of the third time include multiple offsets of the head-mounted display device within the time period. When the first time corresponding to the offset is the time interval between the upper and lower picture frames, the offset of the third time includes all the offsets of the upper and lower picture frames of the head-mounted display device within the time period. For example, the third time includes three picture frames, and the offset of the third time includes the offset of the second picture frame relative to the first picture frame and the offset of the third picture frame relative to the second picture frame.

[0053] S22: If the multiple offsets are all greater than a preset second offset threshold, control the head mounted display device to maintain the offset display.

[0054] The second offset threshold is set by a user, and the second offset threshold may adopt the same value as the first offset threshold.

[0055] In this embodiment, when multiple offsets of the head mounted display device at the third time are all greater than a preset second offset threshold, the head mounted display device can be controlled to maintain the offset display and extend the duration of the offset display.

[0056] See also Figure 3 In a feasible embodiment, S21: in the offset display process, before the step of detecting multiple offsets of the head mounted display device at a third time, it also includes:

[0057] S201: Obtain the continuous display time of the offset display.

[0058] The continuous display time of the offset display refers to the duration from the start of the offset display to the current time.

[0059] S202: Whenever the continuous display time is an integer multiple of a preset fourth time, during the offset display process, a plurality of offsets of the head mounted display device at the third time are detected.

[0060] The fourth time is greater than the third time, and the fourth time is a unit duration of the offset display, and the unit duration is the minimum duration for performing or maintaining the offset display each time. For example, the unit duration is 1 second, and each offset display will be maintained for 1 second. After 1 second, if the head mounted display device is controlled to maintain the offset display in step S22, the offset display will be maintained for another 1 second. Step S22 is a step that can be repeatedly performed.

[0061] Whenever the continuous display time is an integer multiple of the preset fourth time, it means that the unit duration corresponding to the offset display has ended. At this time, it is necessary to obtain multiple offsets of the head-mounted display device at the third time to determine whether to continue to repeat step S22.

[0062] See also Figure 2 In a feasible embodiment, S202: whenever the continuous display time is an integer multiple of a preset fourth time, during the offset display process, the step of detecting a plurality of offsets of the head mounted display device at the third time comprises:

[0063] S2021: Determine a target time interval according to the latest time node of the continuously displayed time and the length of the fourth time.

[0064] The target time interval determined in step S2021 is the time interval corresponding to the last continuous display time of the currently ongoing or continuous offset display.

[0065] S2022: Determine a plurality of third times within the target time interval according to the length of the third time, to obtain a plurality of offsets of each third time.

[0066] Among them, multiple third times can be determined from the target time interval according to the preset time step and the time length of the third time. For example, the target time interval corresponds to 6-7 seconds, the time step is 0.1 seconds, and the time length of the third time is 0.2 seconds. At this time, the multiple third times determined from the target time interval include 6-6.2 seconds, 6.1-6.3 seconds, 6.2-6.4 seconds, 6.3-6.5 seconds...6.8-7.0 seconds.

[0067] In this embodiment, the target time interval can be determined according to the length of the fourth time, and multiple third times can be determined from the target time interval according to the length of the third time, so as to obtain multiple offsets in each third time in the target time interval.

[0068] In a feasible embodiment, after the step of obtaining multiple offsets of each third time, the method further includes:

[0069] If there is an offset less than a preset second offset threshold value among the multiple offsets at each third time, the position of the display content on the head mounted display device is controlled to remain unchanged.

[0070] When there is an offset less than the preset second offset threshold value among the multiple offsets of each third time, it means that the picture frames of each third time are all picture frames generated by slight jitter, that is, the user stops the head-mounted display device at this time, so the head-mounted display device generates corresponding picture frames according to the slight jitter of the user, so it is necessary to start picture filtering to control the position of the display content in the head-mounted display device to remain unchanged. Specifically, the picture filtering function can be started to start picture filtering to filter the picture frames generated by the head-mounted display device according to the slight jitter of the user, thereby improving the stability of the display picture of the head-mounted display device.

[0074] The second display execution module 103 is configured to control the position of the display content on the head mounted display device to remain unchanged if the offset is less than a preset first offset threshold, or if the offset is greater than the preset first offset threshold, but the duration of the consecutive offsets greater than the preset first offset threshold is shorter than a second time, wherein the second time is longer than the first time.
