Detailed Description
In the embodiment of the invention, the picture display mode of the display device in the shutter type 3D picture display system is improved, a pure-color picture is inserted between two monocular frame pictures, and the gray scale value corresponding to the average brightness of the pure-color picture is the same as or similar to the gray scale value corresponding to the average brightness of the previous monocular frame picture, so that a pure-color gray scale picture with smaller brightness contrast and more acceptable human eyes is inserted between the left and right monocular frame pictures, the double image of the left and right monocular frame pictures is eliminated, the crosstalk of the pictures is improved, and the picture quality is enhanced.
In the shutter type 3D picture display system, a display device needs to communicate with shutter glasses and appoint a frame frequency signal of a picture to be displayed, so that the switching frequency of a left switch and a right switch of the shutter glasses is consistent with the frequency of the display device for displaying a left eye list frame picture and a right eye list frame picture, wherein the shutter glasses and the display device can communicate in an infrared or Bluetooth mode. In the embodiment of the present invention, the shutter glasses and the display device communicate with each other through WI-FI, and the specific process is as shown in fig. 1, and includes:
step 101: the shutter glasses transmit a device identification signal to the display apparatus through the WI-FI.
Generally, after the shutter glasses are opened, the shutter glasses send a device identification signal to the display device through WI-FI to inform that the display device is ready to start working. For example: the shutter glasses may transmit a device-identifying signal "1" to the display apparatus through WI-FI.
Step 102: the display device pairs with the shutter glasses according to the received device identification signal.
The display device starts to pair with the shutter glasses after receiving the device identification signal, and continues to detect the external signal if not receiving the device identification signal. For example: when the display device receives the device identification signal "1", it starts to pair with the shutter glasses, and if "1" is not received, it continues to detect the external signal.
Step 103: the display device transmits the acquired frame rate signal to the shutter glasses through WI-FI.
The display apparatus has acquired in advance a frame frequency signal that acquires a picture to be displayed. Generally, a receiving system sends slice source information of a picture to be displayed, and then determines a frame frequency signal of one frame frequency mode from a plurality of preset frame frequency modes as a frame frequency signal of the picture to be displayed according to the received slice source information.
The frame rate signal may be selected from one of frame rate signals of a preset frame rate mode, for example: the default values of the frame frequency signals of the frame frequency modes preset in advance are a plurality of: such as 80Hz, 100Hz, 120Hz, 140Hz, 160Hz, etc. From these, a frame rate signal for the picture to be displayed can be selected, i.e. a frame rate signal with a set frame rate mode is determined as the frame rate signal for the picture to be displayed. The preset selectable frame frequency mode greatly saves the transmission data amount and reduces the error rate in the transmission process. Alternatively, if default values of the frame frequency signals of the frame frequency modes preset in advance are 80Hz, 100Hz, 120Hz, 140Hz and 160Hz, that is, 5 frame frequency modes in total, then the transmission of the frame frequency signals can be realized by using 3-bit. A truth table can be created, and the number of 3-bits is 8, such as 000, 001, 010, 011, 100, 101, 110, 111, each of which corresponds to a default frame rate signal, for example: the 000 corresponds to the default value of the frame frequency signal of 80Hz, and the 001 corresponds to the default value of the frame frequency signal of 100Hz, so that the 000 can be sent to the shutter glasses through WI-FI if the acquired frame frequency signal of the picture to be displayed is the default value of 80 Hz. If the acquired frame frequency signal of the picture to be displayed is a default frame frequency signal of 100Hz, 001 can be sent to the shutter glasses through WI-FI. By analogy, the classification is not performed.
Of course, the embodiments of the invention are not limited thereto, and other frame rate signals can be set as the frame rate signals of the frame to be displayed.
Also, the display device and the shutter glasses transmit through WI-FI.
Step 104: the shutter glasses extract a frame frequency signal and control switching of left and right switches of the shutter glasses according to the extracted frame frequency signal.
Therefore, the shutter glasses and the display device agree on the frame frequency signal of the picture to be displayed, so that the shutter glasses are matched with the display device to display the frequency of the left and right eye single frame pictures, and the viewer can quickly receive two different pictures, thereby forming a 3D effect.
In the embodiment of the invention, the shutter glasses and the display device communicate through the WI-FI, and the WI-FI network has the advantages of wide coverage and high transmission speed, so that the data transmission speed between the shutter glasses and the display device is increased, and the transmission accuracy is improved.
In the embodiment of the invention, the display device acquires the frame frequency signal of the picture to be displayed, and after the display device is successfully communicated with the shutter glasses and sends the frame frequency signal of the picture to be displayed to the shutter glasses in a WI-FI (wireless fidelity), infrared or Bluetooth mode and the like, the display device can display the picture in a left eye single frame scanning display mode and a right eye single frame scanning display mode. Therefore, the display process of each frame of picture is consistent by the display device, and referring to fig. 2, the display device specifically includes:
step 201: the display device receives current monocular frame picture data of a picture to be displayed.
The current monocular frame picture data is left-eye monocular frame picture data or right-eye monocular frame picture data. After the display device and the shutter glasses are successfully communicated, the display device can sequentially receive single-frame image data of an image to be displayed, for example: first left-eye single-frame picture data, first right-eye single-frame picture data, second left-eye single-frame picture data, and second right-eye single-frame picture data. Thus, the current single-eye frame picture data may be the first left-eye single-frame picture data, or the first right-eye single-frame picture data, or the second left-eye single-frame picture data, or the second right-eye single-frame picture data, or other single-frame picture data.
Step 202: the display device displays according to the current monocular frame picture data and determines a first gray-scale value corresponding to the average brightness of the current monocular frame picture.
Illustratively, the 3D display device performs picture display in a progressive scanning manner. As shown in fig. 3, the control of lines G1, G2, G3, and-Gn is turned on in sequence to display the current monocular frame picture data. And in the process of carrying out progressive scanning display, calculating a first gray-scale value corresponding to the average brightness of the current monocular frame picture, namely determining the first gray-scale value corresponding to the average brightness of the current monocular frame picture.
Step 203: the display device displays a first pure color picture matched with the determined first gray scale value before displaying next monocular frame picture data.
In the embodiment of the invention, a plurality of pure color pictures can be preset, and a set interval is reserved between the gray-scale values corresponding to the average brightness of each pure color picture. For example: the signal types are divided into standard data signals and pure-color gray scale signals, if the standard data signals are 8-bit data, namely 256 gray scales, a pure-color gray scale picture can be selected as a selectable insertion picture every 16 gray scale values, namely the difference 16 between the gray scale values corresponding to the set average brightness of the pure-color picture.
In this way, the first gray scale value corresponding to the average brightness of the current monocular frame picture is determined in the above step, so that the gray scale value corresponding to the average brightness of each set pure color picture can be compared with the first gray scale value, and when the difference value between the gray scale value corresponding to the average brightness of one set pure color picture and the first gray scale value is within the set threshold range, the set pure color picture is determined as the first pure color picture. For example: if the difference 16 between the gray levels corresponding to the average brightness of the pure color frames is set, the threshold range may be ± 8, so that when the first gray level is 30, the corresponding pure color frame with the gray level of 32 may be determined as the first pure color frame. When the first gray scale value is 65, the corresponding pure color frame with the gray scale value of 64 may be determined as the first pure color frame. Of course, if the gray scale value is 24, the pure color frame corresponding to the gray scale value of 16 may be determined as the first pure color frame, or the pure color frame corresponding to the gray scale value of 32 may be determined as the first pure color frame.
And after the first pure color picture is determined, opening all the line controls and displaying the first pure color picture. For the display of pure color pictures, a progressive scanning method is not adopted, but all the lines are controlled to be displayed simultaneously. As shown in fig. 3, the control of G1, G2, G3, and-Gn lines are all turned on, and a first pure color picture is displayed. Thus, the time for displaying the pure color picture is shorter than the progressive scanning time, i.e. the time for inserting the picture is shorter.
After the pure color picture is inserted and displayed, the display device displays the next frame picture according to the mode, namely before the next monocular frame picture data is received, the display device displays the first pure color picture matched with the determined first gray scale value, then the next monocular frame picture data is used as the current monocular frame picture data, and the display device displays the current monocular frame picture according to the mode until the last frame picture data is displayed.
By the 3D picture display method, a pure-color gray scale picture which has small brightness contrast and can be accepted by human eyes is inserted between the left and right eye single frame pictures, double images of the left and right eye single frame pictures are eliminated, crosstalk of the pictures is improved, picture quality is enhanced, meanwhile, a viewer cannot see the double-image pictures, and the viewer cannot be injured.
As can be seen from the above process of displaying a 3D screen, the display device, as shown in fig. 4, includes: a receiving unit 410, a scanning display unit 420, and a matching display unit 430. Wherein,
the receiving unit 410 is configured to receive current monocular frame picture data of a picture to be displayed.
The scanning display unit 420 is configured to perform display according to the current monocular frame picture data, and determine a first gray scale value corresponding to the average brightness of the current monocular frame picture.
And a matching display unit 430 for displaying the first pure color picture matched with the determined first gray scale value before displaying the next monocular frame picture data.
Of course, the display device further includes: the communication unit is used for receiving the equipment identification signal of the shutter glasses through the WI-FI, transmitting the acquired frame frequency signal to the shutter glasses through the WI-FI after the equipment identification signal is successfully matched with the shutter glasses, and enabling the shutter glasses to control the switching of a left switch and a right switch of the shutter glasses according to the frame frequency signal
The device also includes: and the acquisition unit is specifically configured to determine, according to the received film source information of the picture to be displayed, a frame frequency signal of one frame frequency mode from a plurality of preset frame frequency modes as the frame frequency signal of the picture to be displayed.
The matching display unit 430 is specifically configured to determine the set pure color picture as the first pure color picture when a difference value between a gray scale value corresponding to the average brightness of the set pure color picture and the first gray scale is within a set threshold range, open all the rows for control, and display the first pure color picture.
As can be seen from the above, the system for displaying 3D frames in a shutter mode according to the embodiment of the present invention is shown in fig. 5, and includes: a display device 100 and shutter glasses 200.
The display device 100 is configured to communicate with the shutter glasses 200, receive current monocular frame picture data of a picture to be displayed, perform display according to the current monocular frame picture data, determine a first gray scale value corresponding to an average brightness of the current monocular frame picture, and display a first pure color picture matched with the determined first gray scale value before displaying next monocular frame picture data.
The shutter glasses 200 are used for communicating with the display device 100, acquiring a frame frequency signal of a picture to be displayed, and controlling the switching of left and right switches of the shutter glasses according to the frame frequency signal.
The display device 100 is specifically configured to receive the device identification signal of the shutter glasses 200 through WI-FI, and after pairing with the shutter glasses 200 is successful, transmit the acquired frame frequency signal to the shutter glasses 200 through WI-FI.
The display apparatus 100 is further specifically configured to determine, according to the received film source information of the picture to be displayed, a frame frequency signal of one frame frequency mode from a plurality of preset frame frequency modes as the frame frequency signal of the picture to be displayed.
The display device 100 is specifically configured to determine a set pure color frame as a first pure color frame when a difference between a gray scale value corresponding to an average brightness of the set pure color frame and the first gray scale value is within a set threshold range, open all the rows, and display the first pure color frame.
In the system for displaying 3D images according to the embodiment of the present invention, the switching of the left and right switches of the shutter glasses may be controlled according to the frame frequency signal without any improvement, in accordance with the prior art. The control frame signal for the left and right eyes as shown before the improvement in fig. 6, in which the scanning time T1 of the monocular frame picture data, the settling time after scanning the monocular frame picture data is T2, and the period time determined according to the frame frequency signal is T, so that T1+ T2 is T. According to fig. 6, in the case where the first pure color picture is not inserted, there is a very small period of time during the time period T1 when the left and right eye single frame images are simultaneously present on the screen, and the picture enters the eyes of the viewer, so that image crosstalk occurs. Or, if the time of the inserted first pure color picture is not too long, there is a risk of crosstalk. Therefore, to further avoid the problem of picture crosstalk, in another embodiment of the present invention, the switching of the left and right switches of the shutter glasses is improved as follows:
the control frame signal for the left and right eyes as shown in fig. 6 after the modification, wherein the closing time of the one-sided glasses is T3, the opening time is T4, and T3 > T1, T3+ T4 ═ T. Therefore, the left and right glasses are closed within the time of T1, wherein image crosstalk may occur, that is, the effect of inserting black pictures is obtained, so that a viewer cannot see double images, and the problem of picture crosstalk is avoided. Therefore, in the system of 3D picture display, the shutter glasses set the closing time T3 and the opening time T4 of the one-sided glasses according to the frame frequency signal, the closing time T3 is greater than the scanning time T1 of the one-sided frame picture data, and the following formula is satisfied:
T3+T4＝T1+T2＝T
for example: assuming that 120Hz is used as the frame frequency signal, T is 8.3ms, T1 is the scanning time of the monocular frame picture data, i.e., the time from the first row of pixels to the last row of pixels, T2 is the stabilization time after the monocular frame picture data is scanned, i.e., the picture holding time (the blanking value except for the actual display pixels), and if the resolution of the display device is 1366 × 768 (actual display pixels), the Total value is 1688 × 806, so T1 is 8.3 × 768/806 is 7.68ms, and T2 is 8.3-7.68 ms. T3 is greater than T1, which may be 8ms, and T4 is 8.3-8 is 0.3 ms.
In the embodiment of the invention, the display device receives the current monocular frame picture data of the picture to be displayed, displays according to the current monocular frame picture data, determines the first gray scale value corresponding to the average brightness of the current monocular frame picture, and displays the first pure-color picture matched with the determined first gray scale value before displaying the next monocular frame picture data. Therefore, a pure-color gray scale picture which has small brightness contrast and can be accepted by human eyes is inserted between the left and right eye single frame pictures, the double images of the left and right eye single frame pictures are eliminated, the crosstalk of the pictures is improved, the picture quality is enhanced, and meanwhile, the double-image picture can not be seen by a viewer and cannot cause damage to the viewer.
In the embodiment of the invention, the display device and the shutter glasses are communicated through the WI-FI, and the WI-FI network has the advantages of wide coverage range and high transmission speed, so that the data transmission speed between the shutter glasses and the display device is increased, and the transmission accuracy is improved.
In addition, the shutter glasses can be improved, the closing time T3 of the single-side glasses is larger than the scanning time T1 of the single-eye frame picture data, meanwhile, the sum of the closing time T3 and the opening time T4 is equal to the period time T determined according to the frame frequency signal, therefore, the left and right glasses are closed within the time T1, wherein the image crosstalk possibly occurs, the effect of inserting the black picture is obtained, a viewer cannot see the double-image picture, and the picture crosstalk problem is avoided.
The display device 100 and the shutter glasses 200 provided in the embodiment of the present invention may be used in a pair, may be used alone, or may be used in a pair with other shutter glasses and display devices, respectively.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
