Description

Image display method, device and terminal for naked-eye 3D display terminal

technical field

The present invention relates to the field of 3D system control, and in particular, to an image display method, device and terminal for a naked-eye 3D display terminal.

Background technique

The naked-eye 3D display technology can provide users with a very good 3D stereoscopic viewing experience. The naked-eye 3D display terminal generally includes a display panel and a light splitting device arranged oppositely. When the naked-eye 3D display is performed on the naked-eye 3D display terminal, the stereoscopic images are first arranged, that is, the left-eye image (referred to as the left image) and the right-eye image (referred to as the left image). The right picture) is arranged and displayed on the display panel according to certain rules, and at the same time, the left eye image is sent to the user's left eye, and the right eye image is sent to the user's right eye, so as to cooperate with the light splitting effect of the light splitting device arranged on the display panel. Allow users to watch 3D images.

At present, most naked-eye 3D display terminals on the market are compatible with a 3D display mode and a 2D display mode, and can switch between the 3D display mode and the 2D display mode according to the actual viewing needs of the user. However, for the same image source, such as the same movie, when displayed in 3D display mode, the left image is sent to the user's left eye, and the right image is sent to the user's right eye. When displayed in 2D display mode, The images sent to the user's left and right eyes are either left or right images. Therefore, when switching between the 3D display mode and the 2D display mode, the content sent to one of the user's eyes is suddenly changed, for example, from the 3D display mode. When switching to 2D display mode, the content sent to the user's left eye changes from the left image to the right image; while switching from 2D display mode to 3D display mode, the content sent to the user's left eye changes from the right image to the left image, which makes the user Eyes are uncomfortable, which in turn degrades the user's viewing experience.

That is, when the naked-eye 3D display terminal is in the 2D display mode, the 2D display mode can be directly adopted to achieve the 2D display effect, and the naked-eye stereoscopic display mode can also be adopted to achieve the 2D display effect. Wherein, when the naked-eye stereoscopic display method is used to achieve the 2D display effect, the views sent to the left eye and the right eye of the user need to be set to the same one, for example, both are left-eye views or both are right-eye views.

Step 102: Determine whether to switch the first display mode to the second display mode.

The first display mode is one of a 3D display mode and a 2D display mode, and the second display mode is another one of a 3D display mode and a 2D display mode. Therefore, in the embodiments of the present invention, it is possible to switch from the 2D display mode to the 3D display mode, and also to switch from the 3D display mode to the 2D display mode.

Preferably, step 102 includes:

acquiring first motion state information of the naked-eye 3D display terminal;

Determine whether to switch the first display mode to the second display mode according to the first motion state information;

or

Detect whether the naked-eye 3D display terminal receives a display mode switching instruction;

When it is detected that the naked-eye 3D display terminal receives a display mode switching instruction, it is determined to switch the first display mode to the second display mode.

That is, in the embodiment of the present invention, it is possible to automatically switch between the 2D display mode and the 3D display mode according to the motion state information indicating the motion state of the naked-eye 3D display terminal. For example, when the naked-eye 3D display terminal moves rapidly or moves violently When the 3D display mode is switched to the 2D display mode, when the naked-eye 3D display terminal moves violently and returns to stillness, the 2D display mode is switched to the 3D display mode. The switching between the 2D display mode and the 3D display mode can also be triggered according to the display mode instruction received by the naked-eye 3D display terminal. Among them, the user can issue a display mode switching instruction through various feasible methods such as touch and voice.

Among them, the automatic switching of the display mode according to the motion state information of the naked-eye 3D display terminal can make the naked-eye 3D display terminal automatically display in different display modes under different motion states, so that under different motion states of the naked-eye 3D display terminal , can also present an eye-friendly display effect.

In addition, the display mode switching instruction is an instruction input by the user in the naked-eye 3D display terminal, and the display mode is switched according to the display mode instruction received by the naked-eye 3D display terminal, so that the naked-eye 3D display terminal can display according to the actual viewing needs of the user. Mode switching to further meet the viewing requirements of different users.

Preferably, the first motion state information includes angular velocity information of the naked-eye 3D display terminal;

When the first display mode is a 3D display mode and the second display mode is a 2D display mode, the step of determining whether to switch the first display mode to the second display mode according to the first motion state information may include:

Determine the target angular velocity according to the angular velocity information of the naked-eye 3D display terminal;

determining whether the absolute value of the target angular velocity is greater than or equal to a first preset threshold;

When the absolute value of the target angular velocity is greater than or equal to the first preset threshold, it is determined to switch the first display mode to the second display mode.

When the first display mode is a 2D display mode and the second display mode is a 3D display mode, the step of determining whether to switch the first display mode to the second display mode according to the first motion state information may include:

Determine the target angular velocity according to the angular velocity information of the naked-eye 3D display terminal;

determining whether the absolute value of the target angular velocity is less than a second preset threshold;

When the absolute value of the target angular velocity is smaller than the second preset threshold, it is determined to switch the first display mode to the second display mode.

Further, in order to avoid errors, when it is determined that the absolute value of the target angular velocity is smaller than the second preset threshold, it is further determined whether the number of times the absolute value of the target angular velocity is continuously smaller than the second preset threshold has reached the preset threshold, when the absolute value of the target angular velocity is smaller than the second preset threshold. When the number of times the value is continuously smaller than the second preset threshold reaches the preset threshold, it is determined to switch the first display mode to the second display mode (ie, switch the 2D display mode to the 3D display mode).

It can be seen from the above that when the absolute value of the target speed determined according to the angle information of the naked-eye 3D display terminal is greater than or equal to the first preset threshold, it is determined to switch the 3D display mode to the 2D display mode; When the absolute value of the target angular velocity determined by the information is smaller than the second preset threshold, it is determined to switch the 2D display mode to the 3D display mode.

Further optionally, the angular velocity information includes the second angular velocity of the naked-eye 3D display terminal rotating around the Y direction, and the step of determining the target angular velocity according to the angular velocity information of the naked-eye 3D display terminal includes: determining the second angular velocity as the target angular velocity;

Further optionally, the angular velocity information includes the first angular velocity of the naked-eye 3D display terminal rotating around the X direction and the second angular velocity of the naked-eye 3D display terminal rotating around the Y direction, and the step of determining the target angular velocity according to the angular velocity information of the naked-eye 3D display terminal includes: The arithmetic square root of the sum of the squares of the first angular velocity and the second angular velocity is determined as the target angular velocity;

Further optionally, the angular velocity information includes the first angular velocity of the naked-eye 3D display terminal rotating around the X direction, the second angular velocity of rotating around the Y direction, and the third angular velocity of rotating around the Z direction. According to the angular velocity information of the naked-eye 3D display terminal, determine The step of the target angular velocity includes: performing weighted summation processing on the first angular velocity, the second angular velocity and the third angular velocity to obtain the target angular velocity;

The X direction is the direction parallel to the width direction of the naked eye 3D display terminal, the Y direction is the direction parallel to the length direction of the naked eye 3D display terminal, and the Z direction is the direction perpendicular to the screen of the naked eye 3D display terminal.

That is, in the embodiment of the present invention, the target angular velocity can be determined according to at least one of the first angular velocity of the naked-eye 3D display terminal rotating around the X direction, the second angular velocity of rotating around the Y direction, and the third angular velocity of rotating around the Z direction.

Wherein, specifically, the above-mentioned steps of performing weighted summation processing on the first angular velocity, the second angular velocity and the third angular velocity to obtain the target angular velocity include:

Get the screen status of the naked-eye 3D display terminal;

When the screen state is the landscape state, according to the first preset formula ω1=a1× _ωX +b1× _ωY +c1× _ωZ , obtain the target angular velocity ω1 in the landscape state;

When the screen state is the vertical screen state, obtain the target angular velocity ω2 in the vertical screen state according to the second preset formula ω2=a2× _ωX +b2× _ωY +c2× _ωZ ;

Among them, ω _X represents the first angular velocity, ω _Y represents the second angular velocity, and ω _Z represents the third angular velocity;

a1, b1, and c1 respectively represent the weight value of the first angular velocity, the weight value of the second angular velocity and the weight value of the third angular velocity in the horizontal screen state;

a2, b2, and c2 respectively represent the weight value of the first angular velocity, the weight value of the second angular velocity, and the weight value of the third angular velocity in the vertical screen state.

In different screen display orientations of the naked-eye 3D display terminal, that is, in the landscape state and the portrait state, the rotation in different directions has different effects on the display effect. Therefore, the above weight value can be set according to the screen display orientation, landscape orientation and portrait orientation. The weight value of each angular velocity in each direction may be different. For example, when displaying in landscape, a1:b1:c1=8:1:1, and when displaying in portrait, a2:b2:c2=1:8:1.

Step 103: When it is determined to switch the first display mode to the second display mode, display the image content in the gradient display mode, thereby switching the first display mode to the second display mode via the gradient display mode.

The gradient display mode is to gradually change the content seen by at least one of the left and right eyes of the user, so that the part of the content is gradually transformed from the content corresponding to the first display mode to the content corresponding to the second display mode. Therefore, the embodiments of the present invention can prevent the user's eyes from feeling uncomfortable when the naked-eye 3D display terminal switches between the 3D display mode and the 2D display mode due to the sudden change of the content sent to the user's eyes, thereby improving the user's viewing experience .

In addition, when the second display mode is the 2D display mode, when switching to the second display mode, displaying the image content in the second display mode; then displaying the image content in the second display mode includes:

Select one of the left eye view and right eye view in the image content for 2D display;

or

Select one of the left eye view and right eye view in the image content as the target left eye view and the target right eye view at the same time;

Naked-eye stereoscopic display is performed according to the target left eye view and the target right eye view.

Wherein, the target left eye view is used for feeding into the user's left eye, and the target right eye view is used for feeding into the user's right eye.

That is, when the naked-eye 3D display terminal is in the 2D display mode, the 2D display mode can be directly adopted to achieve the 2D display effect, and the naked-eye stereoscopic display mode can also be adopted to achieve the 2D display effect. Wherein, when the naked-eye stereoscopic display method is used to achieve the 2D display effect, the views sent to the left eye and the right eye of the user need to be set to the same one, for example, both are left-eye views or both are right-eye views.

Preferably, the above-mentioned displaying of the image content in a gradient display mode includes:

Get the mixed image of the left eye view and right eye view of the image content;

Use the mixed image as the target left eye view and the right eye view as the target right eye view, or, use the mixed image as the target right eye view and the left eye view as the target left eye view, according to the target left eye view and the target right eye view Perform naked-eye stereoscopic display.

That is, the mixed image of the left-eye view and the right-eye view may be sent to the user's left eye as the target left-eye view, or may be sent to the user's right eye as the right-eye view.

As is known to those skilled in the art, each frame of stereoscopic image of a 3D image source includes a left-eye view and a right-eye view. During conventional naked-eye 3D display, the left-eye view and the right-eye view are combined and arranged on the display panel according to certain rules. On the top (ie, the layout), with the light splitting effect of the light splitting device, the left eye view is sent to the user's left eye, and the right eye view is sent to the user's right eye. In this embodiment of the present invention, for the convenience of description and distinction, the 3D image source, that is, the left-eye view and the right-eye view in the image content, are respectively referred to as the left-eye view and the right-eye view, and the view during layout is the input The views of the user's left eye and right eye are referred to as the target left eye view and the target right eye view.

After the mixed image is acquired, the mixed image will be used for naked-eye 3D display. For example, the mixed image is used as the target left-eye view, and the right-eye view is used as the target right-eye view. The image is sent to the left eye of the user, and the view of the right eye is sent to the right eye of the user, so as to realize the naked-eye stereoscopic display based on the mixed image and the right eye view. Of course, the mixed image can also be used as the target right eye view, and the left eye view can be used as the target left eye view, and the layout display can be performed according to the mixed image and the left eye view, that is, the mixed image is sent to the user's right eye, and the left eye view is sent to The user's left eye, so as to realize the naked-eye stereoscopic display according to the mixed image and the left eye view.

Preferably, the above-mentioned step of obtaining the mixed image of the left-eye view and the right-eye view of the image content includes:

Determine the image gradient blending coefficient;

Obtain the mixed image of the left-eye view and the right-eye view in the image content according to the following formula: f(x,y)=g(x,y)×(1-α)+h(x,y)×α;

Among them, f(x, y) represents the pixel value of the pixel whose coordinates are (x, y) in the mixed image, and g(x, y) represents one of the left eye view and the right eye view whose coordinates are (x, y) ), h(x, y) represents the pixel value of the pixel whose coordinates are (x, y) in the other of the left-eye view and the right-eye view, α represents the image gradient blending coefficient, 0≤α≤ 1.

Among them, when g(x, y) represents the pixel value of the pixel whose coordinates are (x, y) in the left eye view, and h(x, y) represents the pixel value of the pixel whose coordinates are (x, y) in the right eye view , the image gradient mixing coefficient represents the ratio of the right eye view in the mixed image; when g(x, y) represents the pixel value of the pixel whose right eye view coordinate is (x, y), h(x, y) represents the left eye view. When the pixel value of the pixel whose coordinates are (x, y) in the eye view, the image gradient blending coefficient represents the ratio of the left eye view in the blended image.

In addition, the pixel value is the RGB value. Wherein, the RGB value includes the R value, the G value and the B value. When the pixel value at each coordinate position in the mixed image is calculated, the R value, the G value and the B value are calculated respectively.

Further, the above-mentioned step of determining the gradient mixing coefficient of the image includes:

acquiring second motion state information of the naked-eye 3D display terminal, and determining an image gradient mixing coefficient according to the second motion state information;

or

Determine the image gradient blending coefficient according to the preset time interval and gradient step size.

That is, in the embodiment of the present invention, the image gradient mixing coefficient has the following two determination methods:

The first type: determine according to the motion state information of the naked-eye 3D display terminal;

The second: Determined according to the preset time interval and gradient step size.

In addition, in the embodiment of the present invention, there are two ways to determine whether the naked-eye 3D display terminal is switched from the first display mode to the second display mode:

The first type: determine according to the motion state information of the naked-eye 3D display terminal;

The second type: determine according to the display mode switching instruction received by the naked-eye 3D display terminal.

It can be seen from the above that the above two methods of whether the naked-eye 3D display terminal is switched from the first display mode to the second display mode and the two methods of determining the image gradient mixing coefficient can be freely combined to obtain different implementation solutions. Two of the preferred combinations are as follows:

Scheme 1: Determine whether to switch the first display mode to the second display mode according to the motion state information of the naked-eye 3D display terminal, and when it is determined to switch the first display mode to the second display mode, according to the motion state of the naked-eye 3D display terminal information to determine the image gradient mixing coefficient, so as to obtain a mixed image of the left-eye view and the right-eye view according to the determined image gradient mixing coefficient, and then perform the naked-eye stereoscopic display of the mixed image and the right-eye view together, or the mixed image Naked eye stereoscopic display together with left eye view.

Option 2: Detect whether the naked-eye 3D display terminal has received a display mode switching instruction, and when it is detected that the naked-eye 3D display terminal has received a display mode switching instruction, determine the image gradient mixing coefficient according to the preset time interval and gradient step, so as to According to the determined image gradient mixing coefficient, a mixed image of the left-eye view and the right-eye view is obtained, and then the mixed image and the right-eye view are displayed together with naked-eye stereoscopic display, or the mixed image and the left-eye view are displayed together with naked-eye stereoscopic .

In addition, the first aspect: the specific process of determining the image gradient mixing coefficient according to the motion state information of the naked-eye 3D display terminal is as follows:

The second motion state information includes the angular velocity information of the naked-eye 3D display terminal; the above-mentioned steps of acquiring the second motion state information of the naked-eye 3D display terminal and determining the image gradient mixing coefficient according to the second motion state information include:

Acquire the angular velocity information of the naked-eye 3D display terminal every preset time interval;

Determine the comparison parameters according to the angular velocity information of the naked-eye 3D display terminal;

If the first display mode is a 3D display mode and the second display mode is a 2D display mode, when the comparison parameter is between the third preset threshold and the fourth preset threshold, the image gradient mixing coefficient is obtained according to the comparison parameter, Until the obtained comparison parameter is greater than or equal to the fourth preset threshold, and/or, if the first display mode is a 2D display mode and the second display mode is a 3D display mode, when the comparison parameter is between the third preset threshold and the first When it is between four preset thresholds, the image gradient mixing coefficient is obtained according to the comparison parameter, until the number of times that the obtained comparison parameter is continuously smaller than the third preset threshold reaches a preset number of times.

Among them, in the process of switching from the 3D display mode to the 2D display mode, the angular velocity information of the naked-eye 3D display terminal is acquired at preset time intervals, and a comparison parameter is determined according to the angular velocity information acquired this time. If the comparison parameter is between the third preset threshold and the fourth preset threshold, the image gradient mixing coefficient can be obtained according to the comparison parameter, and the calculation of the image gradient mixing coefficient is stopped until the obtained comparison parameter is greater than or equal to the fourth preset threshold. , that is, it starts to display in 2D display mode.

In addition, in the process of switching from the 2D display mode to the 3D display mode, the angular velocity information of the naked-eye 3D display terminal is obtained every preset time interval, and a comparison parameter is determined according to the angular velocity information obtained this time. If the comparison parameter is between the third preset threshold and the fourth preset threshold, the image gradient mixing coefficient can be obtained according to the comparison parameter, until the comparison parameter obtained by consecutive preset times is smaller than the third preset threshold, then stop calculating the image gradient mixing coefficient , that is, it starts to display in 3D display mode.

Preferably, the step of determining the comparison parameter according to the angular velocity information of the naked-eye 3D display terminal includes:

Determine the target angular velocity according to the angular velocity information of the naked-eye 3D display terminal obtained each time;

Determine the absolute value of the target angular velocity as the comparison parameter, or perform a weighted summation process on the first preset number of target angular velocities obtained recently, and determine the absolute value of the value obtained after the weighted summation process as the comparison parameter.

That is, in the embodiment of the present invention, there are the following two ways for determining the comparison parameter:

The first type: the absolute value of the target angular velocity determined by the angular velocity information of the naked-eye 3D display terminal obtained every preset time interval is directly used as a comparison parameter;

The second type: Determine the absolute value of the weighted and summed value of the target angular velocity obtained many times recently as the comparison parameter.

Among them, since the subsequent image gradient mixing coefficient is determined according to the comparison parameter, the above-mentioned second method of determining the comparison parameter can avoid the sudden change of angular velocity information causing a large deviation of the image gradient mixing coefficient, thereby avoiding the image gradient mixing. Coefficient of mutation of the resulting blended image.

Further, the angular velocity information includes the second angular velocity of the naked-eye 3D display terminal rotating around the Y direction, and the above-mentioned step of determining the target angular velocity according to the angular velocity information of the naked-eye 3D display terminal obtained each time includes: The angular velocity is determined as the target angular velocity;

or

The angular velocity information includes the first angular velocity of the naked-eye 3D display terminal rotating around the X direction and the second angular velocity of the naked-eye 3D display terminal rotating around the Y direction. The arithmetic square root of the sum of the squares of the first angular velocity and the second angular velocity obtained at one time is determined as the target angular velocity;

or

The angular velocity information includes the angular velocity information including the first angular velocity of the naked-eye 3D display terminal rotating around the X direction, the second angular velocity of rotating around the Y direction, and the third angular velocity of rotating around the Z direction. The above-mentioned angular velocity of the naked-eye 3D display terminal obtained every time information, the steps to determine the target angular velocity include:

Perform a weighted summation process on the first angular velocity, the second angular velocity and the third angular velocity obtained each time to obtain the target angular velocity;

The X direction is the direction parallel to the width direction of the naked eye 3D display terminal, the Y direction is the direction parallel to the length direction of the naked eye 3D display terminal, and the Z direction is the direction perpendicular to the screen of the naked eye 3D display terminal.

That is, in the embodiment of the present invention, the target angular velocity can be determined according to at least one of the first angular velocity of the naked-eye 3D display terminal rotating around the X direction, the second angular velocity of rotating around the Y direction, and the third angular velocity of rotating around the Z direction.

Specifically, the above-mentioned steps of performing a weighted summation process on the first angular velocity, the second angular velocity and the third angular velocity obtained each time to obtain the target angular velocity include:

Get the screen status of the naked-eye 3D display terminal;

When the screen state is the landscape state, according to the first preset formula ω1=a1× _ωX +b1× _ωY +c1× _ωZ , obtain the target angular velocity ω1 in the landscape state;

When the screen state is the vertical screen state, obtain the target angular velocity ω2 in the vertical screen state according to the second preset formula ω2=a2× _ωX +b2× _ωY +c2× _ωZ ;

Among them, ω _X represents the first angular velocity, ω _Y represents the second angular velocity, and ω _Z represents the third angular velocity;

a1, b1, and c1 respectively represent the weight value of the first angular velocity, the weight value of the second angular velocity and the weight value of the third angular velocity in the horizontal screen state;

a2, b2, and c2 respectively represent the weight value of the first angular velocity, the weight value of the second angular velocity, and the weight value of the third angular velocity in the vertical screen state.

In addition, it can be seen from the above that in the process of determining the image gradient mixing coefficient according to the second motion state information, there is a process of "determining the target angular velocity according to the angular velocity information of the naked-eye 3D display terminal included in the second motion state information". In the process of determining whether to switch the first display mode to the second display mode in step 102, there is a process of determining the target angular velocity according to "the first motion state information includes the angular velocity information of the naked-eye 3D display terminal". Wherein, the two specific processes for determining the target angular velocity may be the same or different, and the target angular velocity may be acquired only once, which can be used in step 102 and step 103 . That is, the target angular velocity applied in the process of determining the image gradient mixing coefficient can be the target angular velocity applied when "determining whether to switch the first display mode to the second display mode", or it can be based on the angular velocity information of the naked-eye 3D display terminal. , recalculated using the same or a different algorithm.

Preferably, the above-mentioned step of obtaining the image gradient mixing coefficient according to the comparison parameter includes:

得到参考系数，并将参考系数确定为本次获得的图像渐变混合系数；According to the preset formula

Obtain the reference coefficient, and determine the reference coefficient as the image gradient mixing coefficient obtained this time;

or,

得到参考系数，并将参考系数与上一次获得的图像渐变混合系数中的较大者作为本次获得的图像渐变混合系数；According to the preset formula

Obtain the reference coefficient, and use the larger of the reference coefficient and the image gradient mixing coefficient obtained last time as the image gradient mixing coefficient obtained this time;

Wherein, β represents a reference coefficient, γ represents a comparison parameter, and Δx represents a first preset value.

That is, no matter in the process of switching from 3D display mode to 2D display mode, or in the process of switching from 2D display mode to 3D display mode, the following two methods can be used to determine the image gradient mixing coefficient:

The first type: the reference coefficient obtained at every preset time interval is reduced by the first preset value as the current image gradient mixing coefficient;

The second: after reducing the reference coefficient obtained at every preset time interval by the first preset value, compare it with the image gradient mixing coefficient obtained last time, and use the larger of the two as the current image gradient mixing. coefficient.

Wherein, adopting the above-mentioned second method to determine the image gradation mixing coefficient can avoid the occurrence of picture jitter in the process of the gradation display mode.

Specifically, when the image gradient blending coefficient is determined in the above-mentioned second manner, for example, the first preset value is set to 0.2, and in the process of switching from the 3D display mode to the 2D display mode, for example:

The comparison parameter obtained for the first time is 0.8, then the gradient blending coefficient of this image is 0.6;

The comparison parameter obtained for the second time is 0.85, then the larger of the image gradient mixing coefficient of this time is 0.85-0.2 and the last image gradient mixing coefficient 0.6, which is 0.65;

The comparison parameter obtained for the third time is 0.7, then the image gradient blending coefficient of this time is 0.7-0.2 and the previous image gradient blending coefficient of 0.65, whichever is greater, which is 0.65;

If the comparison parameter obtained for the fourth time is 0.85, the current image gradient blending coefficient is 0.85-0.2 and the previous image gradient blending coefficient of 0.65, whichever is greater, which is 0.65.

Therefore, during the switching process from the 3D display mode to the 2D display mode, even if the motion of the naked-eye 3D display terminal fluctuates, resulting in fluctuations in the obtained comparison parameters, the image gradient mixing coefficient determined by the second method above will not be affected. Influence, thus effectively preventing the shaking of the picture.

Of course, in the process of switching from the 3D display mode to the 2D display mode, the above two methods of determining the image blending gradient coefficient according to the comparison parameters are described by taking the example that the image gradient blending coefficient gradually increases with the angular velocity of the naked-eye 3D display terminal. , but it can be understood that the present invention is not limited to this. During the switching process from the 3D display mode to the 2D display mode, the image gradient blending coefficient can be gradually reduced, that is, no matter how the image gradient blending coefficient changes, the general principle is: The target left-eye view and the target right-eye view for naked-eye stereo display are made closer and closer. Assuming that the mixed image is used as the target left-eye view, the gradient of the image gradient mixing coefficient needs to make the mixed image closer to the right-eye view.

In addition, during the switching process from the 3D display mode to the 2D display mode, the motion of the naked-eye 3D display terminal may gradually become violent, and during this period, the gradient blending coefficient of the image tends to increase or decrease, so that the left eye in the blended image tends to increase or decrease. The proportion of one of the views and the right eye view is increased. Specifically, when the mixed image is used as the target right-eye view, and the image gradient blending coefficient represents the proportion of the left-eye view in the mixed image, during the transition from 3D display mode to 2D display mode, the left-eye view in the mixed image occupies the proportion of the left-eye view. The proportion gradually increases, and the mixed image is getting closer and closer to the left eye view. When switching to 2D display mode, the images sent to the user's left eye and right eye are both left eye views; when the mixed image is used as the target right eye view, the images are gradually mixed. When the coefficient represents the proportion of the right eye view in the mixed image, during the transition from 3D display mode to 2D display mode, the proportion of the right eye view in the mixed image gradually decreases, and the mixed image gets closer and closer to the left eye view. When switching to 2D display mode, the images sent to the user's left and right eyes are both left-eye views; when the mixed image is used as the target left-eye view, and the image gradient blending coefficient indicates the proportion of the right-eye view in the mixed image, During the transition from 3D display mode to 2D display mode, the proportion of the right eye view in the mixed image gradually increases, and the mixed image is getting closer and closer to the right eye view. The images of the eyes are all right eye views. When the mixed image is used as the target left-eye view, and the image gradient blending coefficient indicates the proportion of the left-eye view in the mixed image, the proportion of the left-eye view in the mixed image gradually decreases during the transition from 3D display mode to 2D display mode. small, the mixed image is getting closer and closer to the right eye view, then when switching to 2D display mode, the images sent to the user's left eye and right eye are both the right eye view. It can be seen that, in the transition process from the 3D display mode to the 2D display mode, the transition is performed according to the trend that the proportion of the final 2D displayed view in the mixed image gradually increases, thereby making the human eye feel comfortable.

In addition, specifically, when the image gradient blending coefficient is determined in the above-mentioned second manner, for example, the first preset value is set to 0.2, then in the process of switching from the 2D display mode to the 3D display mode, for example:

The comparison parameter obtained for the first time is 0.8, then the gradient blending coefficient of this image is 0.6;

If the comparison parameter obtained for the second time is 0.7, the larger of the gradient blending coefficient of the current image is 0.7-0.2 and the gradient blending coefficient of the previous image 0.6, which is 0.6;

The comparison parameter obtained for the third time is 0.72, then the larger of the image gradient mixing coefficient of this time is 0.72-0.2 and the last image gradient mixing coefficient 0.6, which is 0.6;

If the comparison parameter obtained for the fourth time is 0.7, the image gradient mixing coefficient of this time is 0.7-0.2 and the larger of the previous image gradient mixing coefficient 0.6, which is 0.6.

Therefore, during the switching process from the 2D display mode to the 3D display mode, even if the motion of the naked-eye 3D display terminal fluctuates, resulting in fluctuations in the obtained comparison parameters, the image gradient mixing coefficient determined by the second method above will not be affected. Influence, thus effectively preventing the shaking of the picture.

In addition, when the naked-eye 3D display terminal is in motion, the human eye is more comfortable for viewing images close to 2D. Therefore, in the process of switching from 2D display mode to 3D display mode, the image gradient blending coefficient takes the maximum value obtained twice adjacently. Therefore, the mixed image is closer to the 2D image, which makes the human eye feel more comfortable.

In the second aspect, according to the preset time interval and gradient step, the specific process of determining the gradient blending coefficient of the image is as follows:

The above steps of determining the gradient blending coefficient of the image according to the preset time interval and gradient step include:

Start the image gradient blending coefficient from the initial value, and decrease the gradient step size every preset time interval. For example, start the image gradient blending coefficient from an initial value of 1, and reduce the gradient step size every preset time interval until the image gradient blending coefficient decreases to 0;

or

Start the image gradient blending coefficient from the initial value, and increase the gradient step size every preset time interval. For example, start the image gradient blending coefficient from an initial value of 0, and increase the gradient step size every preset time interval until the image gradient blending coefficient increases to 1.

The gradient step size for each decrease or increase can be the same or different.

When it is determined to switch from the gradient display mode back to the first display mode, the display of the image content in the first display mode is restored.

Wherein, the above-mentioned step of determining whether to switch from the gradient display mode to the first display mode specifically includes:

Obtain the third motion state information of the naked-eye 3D display terminal;

When the third motion state information satisfies the preset condition, it is determined to switch from the gradient display mode back to the first display mode.

That is, when the display mode of the naked-eye 3D display terminal is switched according to the motion state information of the naked-eye 3D display terminal, there are the following two situations:

Case 1: The naked-eye 3D display terminal enters the gradient display mode from the 2D display mode, and finally does not enter the 3D display mode, but returns to the 2D display mode;

Case 2: The naked-eye 3D display terminal enters the gradient display mode from the 3D display mode, and finally does not enter the 2D display mode, but returns to the 3D display mode.

At least one of the speeds, then according to the angular velocity information of the naked-eye 3D display terminal, a target angular velocity can be determined, and then it is judged whether the target angular velocity satisfies the preset condition, and when the target angular velocity satisfies the preset condition, it means that the naked-eye 3D display terminal It is required to return from the gradient display mode to the first display mode (ie 2D display mode or 3D display mode). The specific process of determining the target angular velocity according to the angular velocity information of the naked-eye 3D display terminal is as described above, and will not be repeated here.

Specifically, when the target angular velocity determined according to the angular velocity information of the naked-eye 3D display terminal is greater than the second preset threshold, the 2D display mode is returned; When the threshold is set, return to 3D display mode.

It can be seen from the above that the image display method for the naked-eye 3D display terminal according to the embodiment of the present invention, the specific implementation examples are as follows:

Embodiment 1. In this embodiment, a mixed image of the left-eye view and the right-eye view in the image content is obtained according to the following formula: f(x,y)=g(x,y)×(1-α)+h (x,y)×α; the mixed image is used as the target right-eye view, the left-eye view is used as the target left-eye view, h(x,y) represents the left-eye view, and g(x,y) represents the right-eye view, as shown in Figure 4 shown, including the following steps:

Step 401: Display in the current display mode, and detect whether a display mode switching instruction is received; the current display mode is a 3D display mode or a 2D display mode. Wherein, when a display mode switching instruction is received and the current display mode is a 3D display mode, step 402 is performed; when a display mode switching instruction is received and the current display mode is a 2D display mode, step 405 is performed.

Step 402 : the current is the 3D display mode, the image gradient blending coefficient is started from the initial value of 0, the gradient step is increased at every preset time interval, the blended image is determined according to the image gradient blending coefficient, and the blended image is used as The target right eye view, the left eye view is used as the target left eye view, so that the naked eye stereoscopic display is performed according to the target left eye view and the target right eye view, so that the mixed image is sent to the user's right eye, and the left eye view is sent to the user's left eye;

Step 403: Determine whether the image gradient mixing coefficient increases to 1, when the image gradient mixing coefficient increases to 1, execute step 404; otherwise, execute step 402;

Step 404: switch to a 2D display mode, wherein the left eye view is fed into both eyes of the user;

Step 405: The current is 2D display mode, and the left eye view is fed to both eyes of the user, then the image gradient mixing coefficient starts from an initial value of 1, and the gradient step size is reduced every preset time interval, according to the image The gradient blending coefficient determines the blended image, and uses the blended image as the target right-eye view and the left-eye view as the target left-eye view, so that the naked-eye stereoscopic display is performed according to the target left-eye view and the target right-eye view, so that the blended image is sent to the user's right eye , the left eye view is sent to the user's left eye;

Step 406: Determine whether the image gradient mixing coefficient is reduced to 0, when the image gradient mixing coefficient is reduced to 0, go to step 407, otherwise go to step 405;

Step 407: Switch to the 3D display mode.

It can be understood that, in the above-mentioned embodiments, the gradation method is adopted in the switching process from 2D to 3D and the switching process from 3D to 2D, but the present invention is not limited to this, and at least one of the two switching methods may be adopted. Gradient switching, considering the complexity of 3D display loading, the process from 2D to 3D display takes a certain amount of time. Therefore, it is preferable to use the above gradient method in the process of 3D to 2D, but in the process of 2D to 3D, it is not necessary to Gradient display is performed.

Embodiment 2: The process of switching from the 3D display mode to the 2D display mode in the process of changing the naked-eye 3D display terminal from the static state to the moving state.

In this embodiment, a mixed image of the left-eye view and the right-eye view in the image content is obtained according to the following formula: f(x,y)=g(x,y)×(1-α)+h(x,y )×α; the mixed image is used as the target right-eye view, the left-eye view is used as the target left-eye view, h(x, y) represents the left-eye view, and g(x, y) represents the right-eye view.

Specifically, as shown in FIG. 5 , this embodiment includes the following steps:

Step 501: Currently displaying in a 3D display mode, obtaining the angular velocity information of the naked-eye 3D display terminal once every preset time interval, and determining the target angular velocity according to the angular velocity information;

Step 502: determine whether the absolute value of the target angular velocity is greater than or equal to the first preset threshold, when the absolute value of the target angular velocity is greater than or equal to the first preset threshold, execute step 503, otherwise execute step 501; wherein, the absolute value of the target angular velocity The value is greater than or equal to the first preset threshold, indicating that the motion of the naked-eye 3D display terminal becomes violent. At this time, if the naked-eye 3D display terminal is still displayed in 3D display mode, problems such as crosstalk will occur, which will affect the user's viewing effect. Therefore, , in this embodiment, when the absolute value of the target angular velocity is greater than or equal to the first preset threshold, step 503 is performed, and then the 2D display mode can be switched;

Step 503: When the absolute value of the target angular velocity is greater than or equal to the first preset threshold, perform a weighted summation process on the first preset number of target angular velocities obtained recently, and calculate the absolute value of the value obtained after the weighted summation process. Determined as a comparison parameter.

The absolute value of the target angular velocity is greater than or equal to the first preset threshold, indicating that the motion state of the naked-eye 3D display terminal becomes severe, and steps 503 to 506 need to be executed to enter the gradient display mode. Among them, in the gradient display mode, since the image gradient mixing coefficient is determined according to the comparison parameter, the absolute value of the numerical value obtained after the weighted summation of the first preset number of target angular velocities obtained recently is used as the comparison parameter. Avoiding sudden change in angular velocity information leads to a large deviation of the image gradient mixing coefficient, thereby avoiding the sudden change of the mixed image obtained according to the image gradient mixing coefficient.

Step 504: Determine whether the comparison parameter is between the third preset threshold and the fourth preset threshold, when the comparison parameter is between the third preset threshold and the fourth preset threshold, perform step 505, when the comparison parameter is less than or When it is equal to the third preset threshold, go to step 501, and when the comparison parameter is greater than or equal to the fourth preset threshold, go to step 507; wherein, the third preset threshold may be greater than or equal to the first preset threshold.

Step 505: Decrease the comparison parameter by the first preset value (wherein, after reducing the first preset value, if it is less than or equal to 0, it is set to 0; The image gradient mixing coefficients are compared, and the larger of the two is taken as the current image gradient mixing coefficient.

Step 506: Determine the mixed image according to the image gradient mixing coefficient, and use the mixed image as the target right eye view and the left eye view as the target left eye view, so that the mixed image is sent to the user's right eye and the left eye view is sent to the user's left eye.

Step 507: Switch to the 2D display mode (wherein, the left eye view is fed to both eyes of the user). Wherein, when the naked-eye 3D display terminal enters the 2D display mode, one can be selected from the left-eye view and the right-eye view in the image content for 2D display, or one can be selected from the left-eye view and the right-eye view in the image content. The frame is used as the target left-eye view and the target right-eye view at the same time, and then the naked-eye stereoscopic display is performed according to the target left-eye view and the target right-eye view. Wherein, the case where the naked-eye stereoscopic display method is used to achieve the 2D display effect may be a special display case when the image gradient mixing coefficient is equal to 1 or 0 in the gradient display mode.

In this embodiment, switching to the 2D display mode may be to set the image gradient mixing coefficient to 1, then the mixed image is the left-eye view, which is the target right-eye view, and the left-eye view is the target left-eye view, and the target left-eye view is The view is the same as the right-eye view of the target, both are left-eye views. When the naked eye is displayed in 3D, it will present a 2D display effect.

It can be seen from the above that in this embodiment, it can be determined whether to switch the 3D display mode to the 2D display mode through steps 501 to 502, and when the absolute value of the target angular velocity is greater than or equal to the first preset threshold, it is determined that the 3D display mode needs to be converted into the 2D display mode. The display mode is switched to the 2D display mode, thereby entering the gradient display mode through steps 503 to 506 , and when the obtained comparison parameter is greater than or equal to the fourth preset threshold, the 2D display mode is switched. Wherein, in the process of changing the naked-eye 3D display terminal from a static state to a vigorous motion state, the obtained comparison parameter gradually becomes greater than or equal to the fourth preset threshold from between the third preset threshold and the fourth preset threshold Therefore, in the process of changing the naked-eye 3D display terminal from the static state to the vigorous motion state, it can be switched from the 3D display mode to the 2D display mode via the gradient display mode.

Real-time mode 3: In this embodiment, after the naked-eye 3D display terminal is switched to the 2D display mode after vigorous motion, the process of changing from the motion state to the static state gradually changes from the 2D display mode to the 3D display mode again. the process of.

Wherein, in this embodiment, the mixed image of the left-eye view and the right-eye view in the image content is obtained according to the following formula: f(x,y)=g(x,y)×(1-α)+h(x ,y)×α; the mixed image is used as the target right-eye view, the left-eye view is used as the target left-eye view, h(x,y) represents the left-eye view, and g(x,y) represents the right-eye view.

Specifically, as shown in Figure 6, this real-time mode includes the following steps:

Step 601: Currently displaying in a 2D display mode, obtaining the angular velocity information of the naked-eye 3D display terminal once every preset time interval, and determining the target angular velocity according to the angular velocity information;

Wherein, when the naked-eye 3D display terminal displays in 2D display mode, one of the left-eye view and right-eye view in the image content can be selected for 2D display, or one of the left-eye view and right-eye view in the image content can be selected for 2D display. Select one image as the target left-eye view and target right-eye view at the same time, and then perform naked-eye stereoscopic display according to the target left-eye view and the target right-eye view. Among them, the case where the naked-eye stereoscopic display method is used to achieve the 2D display effect is a special display case when the image gradient mixing coefficient is equal to 1 or 0 in the gradient display mode.

In this embodiment, the 2D display mode may be a special case of setting the image gradient blending coefficient to 1 in the gradient display mode.

Step 602: determine that the absolute value of the target angular velocity is less than the second preset threshold, when the absolute value of the target angular velocity is less than the second preset threshold, execute step 603, otherwise execute step 601;

The absolute value of the target angular velocity is less than the second preset threshold, indicating that the motion state of the naked-eye 3D display terminal becomes slow and tends to be stationary. At the second preset threshold, perform step 603, and then switch to the 3D display mode;

Step 603: When the absolute value of the target angular velocity is less than the second preset threshold, perform weighted summation processing on the first preset number of target angular velocities obtained recently, and determine the absolute value of the value obtained after the weighted summation processing as compare parameters;

The absolute value of the target angular velocity is greater than or equal to the first preset threshold, indicating that the motion state of the naked-eye 3D display terminal becomes slow, and steps 603 to 606 need to be executed to enter the gradient display mode. Among them, in the gradient display mode, since the image gradient mixing coefficient is determined according to the comparison parameter, the absolute value of the numerical value obtained after the weighted summation of the first preset number of target angular velocities obtained recently is used as the comparison parameter. Avoiding sudden change in angular velocity information leads to a large deviation of the image gradient mixing coefficient, thereby avoiding the sudden change of the mixed image obtained according to the image gradient mixing coefficient.

Step 604: Determine whether the comparison parameter is between the third preset threshold and the fourth preset threshold, when the comparison parameter is between the third preset threshold and the fourth preset threshold, perform step 605, when the comparison parameter is greater than or When it is equal to the fourth preset threshold, step 601 is performed, and when the number of times that the comparison parameter is less than or equal to the third preset threshold reaches the preset number of times, step 607 is performed.

Step 605: Decrease the comparison parameter by a first preset value (wherein, if the first preset value is reduced, if it is less than or equal to 0, it is set to 0; The image gradient mixing coefficients are compared, and the larger of the two is taken as the current image gradient mixing coefficient.

Step 606: Determine the mixed image according to the image gradient mixing coefficient, and use the mixed image as the target right eye view and the left eye view as the target left eye view, so that the mixed image is sent to the user's right eye and the left eye view is sent to the user's left eye.

Step 607: Switch to the 3D display mode.

It can be seen from the above that in this embodiment, it can be determined whether to switch the 2D display mode to the 3D display mode through steps 601 to 602, and when the absolute value of the target angular velocity is less than the second preset threshold, it is determined that the 2D display mode needs to be changed. Switch to the 3D display mode, thereby entering the gradient display mode through steps 603-606, and switch to the 3D display mode when the number of times the obtained comparison parameter is less than or equal to the third preset threshold reaches the preset number of times. Wherein, during the process of changing the naked-eye 3D display terminal from a violent motion state to a static motion state, the obtained comparison parameter gradually changes from being between the third preset threshold and the fourth preset threshold to a continuous preset number of times less than or equal to With the third preset threshold, the naked-eye 3D display terminal can be switched from the 2D display mode to the 3D display mode via the gradient display mode during the process of changing from a violent state to a static motion state.

It should be noted that, in the second embodiment, if between steps 505 to 506, the target angular velocity determined according to the angular velocity information of the naked-eye 3D display terminal is smaller than the first preset threshold for consecutive preset times, then return to the original 3D display mode. Similarly, in real-time mode 3, if the target angular velocity determined according to the angular velocity information of the naked-eye 3D display terminal is greater than the second preset threshold between steps 605-606, the original 2D display mode is returned.

In addition, assuming that the motion state of the naked-eye 3D display terminal is as shown in Figure 7, it can be seen from the above analysis that the naked-eye 3D display terminal is in the 3D display mode in the OA segment, in the gradient display mode in the AB segment, and in the BC segment and CD segment. In the 2D display mode, it is in the gradient display mode in the DE segment, and in the 3D display mode in the EF segment.

Among them, in the process of switching the naked-eye 3D display terminal from the 3D display mode to the 2D display mode via the gradient display mode of the AB segment, since the actual motion state of the naked-eye 3D display terminal cannot continue to show a trend of rapidity, that is, during this process, there are In the case of fluctuations, by setting the image gradient blending coefficient to take the larger of two consecutive times, it is possible to avoid the display screen shaking due to fluctuations in the motion state of the naked-eye 3D display terminal.

In the same way, during the process of switching from the 2D display mode to the 3D display mode of the naked-eye 3D display terminal via the gradient display mode of the DE segment, the actual motion state of the naked-eye 3D display terminal cannot continue to show a slowing trend, that is, during this process. There are fluctuations, and by setting the image gradient blending coefficient to take the larger of two consecutive times, it is also avoided that the display screen shakes due to fluctuations in the motion state of the naked-eye 3D display terminal.

To sum up, in the process of displaying the image content by the naked-eye 3D display terminal in either the 3D display mode or the 2D display mode, it can be determined that the display needs to be performed between the 3D display mode and the 2D display mode. When switching, the image content is displayed in a gradient display mode, thereby gradually changing the content seen by at least one of the left and right eyes of the user, and gradually transforming the part of the content from the content corresponding to the 3D display mode to the content corresponding to the 2D display mode, Or gradually change from the content corresponding to the 2D display mode to the content corresponding to the 3D display mode, so as to avoid the user's eyes being caused by the sudden change of the content sent to the user's eyes when the naked-eye 3D display terminal switches between the 3D display mode and the 2D display mode. Eyes feel uncomfortable, which improves the user's viewing experience.
