All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to solve the problem of the prior art that the displacement is generated between the head of the viewer and the display device, so that the displayed ultra-high definition image is visually dithered, according to a first aspect of the present invention, there is provided an ultra-high definition image display dithering compensation method, as shown in fig. 1, comprising the steps of:
in step 100, acquiring first position information of a display device and second position information of a head of a viewer, and determining anchoring information between the display device and the head of the viewer;
in step 200, obtaining display parameter information of a display device and image information of an ultra-high definition image, and displaying the ultra-high definition image on the display device based on the anchoring information;
in step 300, first jitter offset data of a display device in a first time and second jitter offset data of a head of a viewer are acquired, and offset difference data is determined based on the first jitter offset data and the second jitter offset data;
in step 400, a dither compensation is performed on an ultra-high definition image displayed on a display device based on offset difference data.
Based on the specific step 100 of the above embodiment, it should be noted that: anchoring information between the display device and the head of the viewer is determined by determining the coordinate position of the display device and the coordinate position of the head of the viewer, while based on the relative displacement between the display device and the head of the viewer. By determining the anchor information, the display device can set the display parameters of the ultra-high definition image on the display device based on the anchor information, and at the same time, when the relative shake is generated between the display device and the head of the viewer, the display device can compensate the shake generated by the ultra-high definition image in the display process based on the relevant parameters determined by the anchor information. The method comprises the following steps:
as shown in fig. 2, in step 100, the first position information of the display device and the second position information of the head of the viewer are acquired, and the anchoring information between the display device and the head of the viewer is determined, which includes the following specific steps:
step 101, acquiring first position information of a display device, wherein the first position information comprises X-axis and Y-axis data of the display device; the display device in the embodiment of the application may be a portable intelligent display device such as a smart phone, a smart tablet, a smart watch, or a non-portable display device such as a projector. When the first position information of the display device is acquired, a coordinate system is established by using a display plane of the display device, a center point of the display device is used as a coordinate origin, and the transverse direction of a display picture is an X axis and the longitudinal direction of the display picture is a Y axis, so that in an initial state, X-axis data and Y-axis data of the display device, namely, data of the transverse width, the longitudinal width and the like of the display device can be determined.
Step 102, obtaining second position information of the head of the viewer, wherein the second position information comprises X-axis, Y-axis and angle data relative to the first position information; in this step, it should be noted that, in general, the head of the viewer is viewed toward the display device, taking the axis perpendicular to the display device as the Z axis, and projecting the X axis and Y axis data of the head of the viewer into the coordinate system through the mapping relationship, and the face of the viewer is not completely parallel to the display plane of the display device, so that the face of the viewer forms a certain angle with the coordinate system, and is recorded as the initial angle data α. Meanwhile, based on the noted X-axis, Y-axis and angle data α, the difference value is compared with the X-axis and Y-axis data of the display device, so as to obtain second position information of the head of the viewer, and in the second position information, the X-axis data is as follows:
；
wherein,for X-axis data in the first position information, < >>X-axis data for a viewer's head;
the Y-axis data are as follows:
；
wherein,for Y-axis data in the first position information, < >>Y-axis data for the viewer's head;
therefore, the second position information of the head of the viewer in the coordinate system with respect to the first position information, that is, the X-axis, Y-axis, and angle data α in the second position information is obtained by the above calculation formula.
Step 103, determining initial distance information between the display device and the head of the viewer; as noted in step 102 above, with the axis perpendicular to the display device as the Z-axis, the distance of the viewer's head from the display device may be monitored by a camera or other sensor (e.g., an infrared sensor) on the display device, thus yielding Z-axis data in the second location information as the initial distance information.
Step 104, determining anchor information between the display device and the viewer's head based on the initial distance information and the second position information. Therefore, after the above steps 102 and 103, a plurality of data information of the head of the viewer with respect to the display device, specifically, X-axis data, Y-axis data, and angle data α in the second position information, and initial distance information of the head of the viewer with respect to the display device in the Z-axis are obtained, and these information are summarized as initial anchor information.
As described above, in the embodiment of the present application, the display device displays the ultra-high definition image to be displayed on the screen according to the original data of the ultra-high definition image, and the state of the anchor information is determined as the initial viewing state of the viewer. When a relative displacement occurs between the head of the viewer and the display device, a shake compensation display is performed on the ultra-high definition image on the display device based on the change of the anchor information.
Based on the specific step 100 of the above embodiment, further, in step 200, display parameter information of the display device and image information of the ultra-high definition image are acquired, and the ultra-high definition image is displayed on the display device based on the anchor information, as shown in fig. 3, including the steps of:
step 201, obtaining display parameter information of a display device; in this step, the display parameters of the display device include parameter information such as a display color gamut, a display resolution, and a display brightness, so as to facilitate adjustment of the display parameters according to the characteristics of the ultra-high definition image.
Step 202, obtaining display pixel value information of an ultra-high definition image, and determining the optimal resolution of the display device based on the display pixel value information of the ultra-high definition image; specifically, first, image data information of the ultra-high definition image, such as pixel value information to be displayed, is acquired, display parameter information of the display device has been determined in step 201, and based on the display parameter information and the information of the ultra-high definition image, the ultra-high definition image is displayed with an optimal resolution, so as to improve viewing experience of a viewer.
And step 203, adjusting the display size of the ultra-high definition image on the display device based on the anchoring information. In the above step, in the case where the initial anchor information has been determined, the ultra-high definition image is initially displayed in the display screen size of the display device, and the display size of the ultra-high definition image is adjusted when a shake displacement occurs between the head of the viewer and the display device, particularly when the distance between the head of the viewer and the display device in the Z-axis varies. Illustratively, when the distance between the head of the viewer and the display device becomes large and exceeds the initial distance information, the ultra-high definition image becomes large to be displayed; and the ultra-high definition image is displayed smaller when the distance between the head of the viewer and the display device becomes smaller and smaller than the initial distance information.
In step 203, adjusting a display size of the ultra high definition image on the display device based on the anchor information, comprising:
acquiring the original display size of the ultra-high definition image on the display device; in the present embodiment, the ultra high definition image is displayed on the display device with the optimal display resolution, and in general, the display size of the ultra high definition image is adapted to the display screen size of the display device.
Determining a display adjustment factor based on the anchor information; in this step, the X-axis data, Y-axis data, Z-axis data, and angle data α in the initial anchor information, at this time, the ultra-high definition image is adapted to the size of the display screen of the display device for display, and the display adjustment coefficient is determined by the above anchor information as follows:
wherein ρ is a display adjustment coefficient,weight of X-axis data in the second position information, < >>Weight of Y-axis data in the second position information, +.>Is the weight of the Z-axis data in the second position information.
Wherein the angle data α is used to define an angular change between the head of the viewer and the display device, and no adjustment of the display is made, regardless of the change in the second position information, when the angular change between the head of the viewer and the display device exceeds a threshold value. Illustratively, the initial angle data α is 30 °, the threshold value is set to 60 °, and when the angle of the head of the viewer to the display device is 60 ° or more, the ultra-high definition image in the display device displays the initial size regardless of the change in the X-axis data, the Y-axis data, and the Z-axis data in the second position information.
Further, an adjusted display size of the adjusted ultra-high definition image on the display device is determined based on the display adjustment factor and the original display size. Based on the above embodiment, the anchoring information determines the display adjustment coefficient, and when the distance between the head of the viewer and the display device in the Z-axis is changed, the adjustment is performed according to the display adjustment coefficient and the original display size of the ultra-high definition image, specifically:
wherein,for a change in distance between the viewer's head and the display device, ρ is a display adjustment factor,for the original display size of the ultra high definition image, < >>The display size is adjusted for the ultra-high definition image.
In step 300, where first jitter offset data of a display device at a first time and second jitter offset data of a viewer's head are acquired, offset difference data is determined based on the first jitter offset data and the second jitter offset data, as shown in fig. 4, comprising the steps of:
step 301, obtaining first jitter offset data of a display device relative to first position information in a first time; in this embodiment of the present application, the first time is limited in a short time, for example, 0.3S, so that the jitter compensation can have a faster response speed, and the compensation effect is improved. Specifically, when the display device is dithered, it is offset with respect to the first position information in the established coordinate system, including X-axis offset data and Y-axis offset data, denoted as first dithered offset data.
Step 302, obtaining second jitter offset data of the head of the viewer relative to second position information in a first time; likewise, in the embodiment of the present application, when the head of the viewer is dithered, the head of the viewer is offset with respect to the second position information in the established coordinate system, including X-axis offset data, Y-axis offset data, Z-axis offset data, and angle offset data, which are denoted as second dithering offset data.
In step 303, a difference between the first jitter offset data and the second jitter offset data is calculated as offset difference data. Based on the information described in the above steps 301 and 302, in which the first shake offset data of the first position information on the display device and the second shake offset data of the second position information on the head of the viewer have been described, the visual shake offset of the ultra-high definition image can be determined by calculating the difference data of the first shake offset data and the second shake offset data, and specifically further comprising the steps of:
in the step, first offset difference value of the head of the viewer relative to the display device in the X axis is obtained, first offset data of the first position information in the X axis is obtained, then offset data of the second position information in the X axis is obtained, and difference value operation is carried out to obtain the first offset difference value of the head of the viewer relative to the display device in the X axis.
And in the same way, in the step, firstly, the offset data of the first position information in the Y axis is acquired, then the offset data of the second position information in the Y axis is acquired, and then the difference operation is carried out, so that the second offset difference value of the head of the viewer in the Y axis relative to the display device is obtained.
Acquiring the angle change of the head of the viewer relative to the display device as a third offset difference value, wherein in the step, the angle between the display device and the face plane of the viewer can be recorded in real time through the camera, and the angle change difference value relative to the original angle data alpha is used as the third offset difference value; the third offset difference calculated in this step is primarily indicative of the angle between the viewer's head relative to the display device and no adjustment is made to the display of the ultra-high definition image when the threshold is exceeded.
Obtaining a fourth offset difference value of the head of the viewer relative to the display device in distance, and in the same way, firstly obtaining offset data of the second position information in the Z axis, and then carrying out difference value operation with the original distance data in the Z axis to obtain a fourth offset difference value of the head of the viewer relative to the display device in the Z axis;
determining offset difference data based on the first offset difference, the second offset difference, the third offset difference, and the fourth offset difference, specifically as follows:
acquiring a display adjustment coefficient; in the step in this embodiment, the adjustment coefficient is displayed as an initial determination value ρ;
determining first following compensation data of the ultra-high-definition image in the X-axis direction based on a first offset difference value, specifically, taking an absolute value of a product of the first offset difference value and a display adjustment coefficient rho as the first following compensation data, and adjusting the display position of the ultra-high-definition image on the X-axis of display equipment according to the first following compensation data;
determining second following compensation data of the ultra-high-definition image in the Y-axis direction based on a second offset difference value, wherein the absolute value of the product of the second offset difference value and a display adjustment coefficient rho is used as the second following compensation data, and then adjusting the display position of the ultra-high-definition image on the Y-axis of the display device according to the second following compensation data;
determining third follow-up compensation data of the ultra-high definition image in angle based on the third offset difference value; the third offset difference calculated in this step is primarily indicative of the angle between the viewer's head relative to the display device and no adjustment is made to the display of the ultra-high definition image when the threshold is exceeded.
Determining fourth following compensation data of the ultra-high definition image in distance based on a fourth offset difference value, specifically, taking an absolute value of a product of the fourth offset difference value, an original display size and a display adjustment coefficient rho as the fourth following compensation data, and adjusting the display size of the ultra-high definition image on a Z axis of display equipment according to the fourth following compensation data, specifically, when the fourth offset difference value is a negative number, reducing the ultra-high definition image, and when the fourth offset difference value is a positive number, increasing the ultra-high definition image;
in summary, the position or the size of the ultra-high definition image on the X-axis, the Y-axis, and the Z-axis may be adjusted by determining the shake compensation data based on the first, second, third, and fourth following compensation data, so as to implement shake compensation.
In the above steps, the shake compensation display of the ultra-high definition image on the display device is realized, but if the display boundary of the image exceeds the boundary of the display device, it is necessary to set to ensure that the display of the key information in the ultra-high definition image is not affected. Thus, it further comprises:
