[ First embodiment ]
In the existing display control device, when a user plays a video source sent by an upper computer such as a PC or a front-end video processor, there are two main possibilities that the display screen cannot display a 3D effect, on the one hand, the display control device is normal, but the setting of the upper computer is improper or other abnormal conditions occur, so that the input video source is problematic, and therefore, even if the display control device is normal, the problematic video source cannot be displayed as a normal 3D display screen; on the other hand, the video source sent by the upper computer is normal, but the display control device is abnormal, so that the normal video source cannot be processed correctly, and cannot be displayed into a normal 3D display picture. However, when such a problem occurs, it is difficult for the user to judge the failure caused by the above-described case in particular, and it is very inconvenient for the technician to check. Therefore, in order to improve the human efficiency and reduce the scope of troubleshooting problems to quickly troubleshoot the fault location, a first embodiment of the present invention provides a 3D picture display test method, as shown in fig. 1, including:
step S1: responding to user operation to obtain a test signal;
Step S3: acquiring a local 3D test picture according to the test signal;
Step S5: and processing and outputting the 3D test picture for testing the correctness of the 3D picture display based on human eye vision.
The above-mentioned 3D picture display test method is executed in a display control device, for example, where the display control device includes a normal mode and a test mode, where the display control device normally processes a video source sent by an upper computer to control an LED display screen to display a video source picture, and the test mode executes the 3D picture display test method provided in this embodiment. The test signal in step S1 is generated, for example, after the user operates a test mode switch on the display control device, where the test mode switch may be a mechanical key or a touch screen switch. Specifically, for example, the user outputs a test signal once each time he presses the test mode switch, and the display control apparatus switches from the normal mode to the test mode, for example, after acquiring the test signal.
In one embodiment, step S3 is preceded by, for example, further comprising:
step S2: and generating the 3D test picture according to preset picture parameters.
Step S2 may be, for example, after step S1, generating a 3D test frame according to the received test signal. Or, before step S1, for example, the display control device may be powered on or the 3D test device may first generate a 3D test screen no matter whether it is in the test mode or not after entering the 3D mode, and then, for example, perform an operation such as buffering, so that the 3D test screen may be directly acquired when needed. Fig. 2 is a schematic flow chart of a 3D screen display testing method according to another embodiment of the present invention, and step S2 is performed between step S1 and step S3 based on the 3D screen display testing method shown in fig. 1. The preset frame parameters include, for example, a resolution, a frame rate, mode information, a frame start coordinate, and frame pattern information of the 3D test frame, for example, a resolution of 1920×1080, which means a 3D test frame Width (Width) of 1920 and a Height (Height) of 1080. For example, a frame rate of 60Hz indicates that 60 frames of images are produced per second. The mode information corresponds to a video mode of the 3D test picture, the video mode is selected from a left-right mode, an up-down mode or a continuous frame mode, wherein the video mode refers to a storage mode of the 3D image, for example, a picture width of final display of the left-right mode (Side by Side) is half of an original picture, for example, a 3D picture with a resolution of 1920×1080, a picture width of final display is 960×1080, and a left half picture corresponding to a left eye and a right half picture corresponding to a right eye are sequentially played; the final display of the Top-down mode (Top-and-Botton) has half the height of the original 3D picture, for example, the resolution is 960 x 1080, the final display has a picture width of 960 and a height of 540, and the upper half picture corresponding to the left eye and the lower half picture corresponding to the right eye are sequentially played; the width and the height of the final display of the continuous frame mode are unchanged, and two adjacent frames are played alternately corresponding to left eyes and right eyes. The picture pattern information corresponds to the pattern information and includes left and right pattern information, up and down pattern information, and adjacent frame pattern information, the pattern information of the picture is used to represent a pattern displayed in a specific area of the picture (or content to be displayed for each pixel), for example, a solid color pattern or a gray scale, a diagonal line, a square, a 3D picture pattern, for example, a left half picture is displayed as a solid red color, a right half picture is displayed as a solid blue color, and the picture pattern information may be stored in the form of RGB values for each pixel, or the like. For example, in the picture parameters preset for a certain 3D test picture, the video information corresponds to a left-right mode, and the picture pattern information includes left-right pattern information (for example, left-right blue, pure color); the video information corresponds to the up-down mode, and the picture pattern information includes up-down pattern information (e.g., up-red, down-blue, solid color); the video information corresponds to a continuous frame mode and the picture pattern information includes adjacent frame pattern information (e.g., red-blue alternating, solid color for adjacent frames). Of course, what is included in the pattern information is presented here in a text form for easier understanding, and is not intended as a condition for limiting understanding of the present embodiment.
The following is a description of the relation between the parameters of the preset frame and the generated 3D test frame in text form, for example, the preset parameter a corresponding to a certain 3D test frame a is expressed as follows:
a: resolution: 1920×1080, frame rate: 60Hz, mode information: left-right mode, left eye starting coordinates: (0, 0), right eye starting coordinates: (960,0) screen pattern information: left dark gray, right light gray, solid color)
Referring to fig. 3, which is a schematic diagram of a 3D test frame a, according to the preset frame parameters, the process of generating the 3D test frame a is as follows: 60 frames of images are generated per second, each frame of images is 1920 times higher, the starting coordinates of the left eye are default (0, 0), the starting coordinates of the right eye are default (960,0), the picture pattern information is left and right pattern information (pure-color pictures of left dark gray and right light gray) corresponding to a left and right mode, after final display, the left eye of the picture seen by the 3D glasses sees dark gray areas of 960 times 1080 on the left, and the right eye sees light gray areas of 960 times 1080 on the right. It should be noted that, after the 3D test frame is generated according to the preset frame parameters, the 3D test frame itself includes the data contents of the parameters, and the parameters can still be stored and read in the subsequent processing process.
The preset frame parameters are not limited by the video source parameters sent by the upper computer, and may be, for example, the display control device leaves the factory and is self-contained, for example, may also be selected or set by a user according to actual requirements, and in one embodiment, the 3D frame display test method further includes, for example:
Step S4: and responding to the parameter input operation of the user, and acquiring the preset picture parameters.
Step S4 may be performed at any position before step S2, and step S4 may be further performed after step S4. Referring to fig. 2, step S4 is performed, for example, before step S1.
Or in another embodiment, step S2 further comprises, for example:
Step S21: and selecting target picture parameters from a plurality of groups of preset picture parameters according to the parameter selection control signals to generate a target 3D test picture. Examples of the plurality of predetermined picture parameters include:
b: resolution 1920×1080, frame rate 60HZ, mode information: left-right mode, left eye starting coordinates: (0, 0), right eye starting coordinates: (960,0) screen pattern information: left red, right blue, solid color ];
c: resolution 1080×1920, frame rate 60HZ, mode information: up and down mode, left eye starting coordinates: (0, 0), right eye starting coordinates: (0, 960), screen pattern information: upper red and lower yellow, solid color ].
The parameter selection control signal is generated, for example, by a user operating a selection button of the display control device, where, for example, a "test B" button and a "test C" button are provided on the control device, and when the user presses the "test B" button, the user selects B as a target picture parameter to generate a 3D test picture B of a left-right mode corresponding to the B group, and when the user presses the "test C" button, the user selects C as a target picture parameter to generate a 3D test picture C of an up-down mode corresponding to the C group, or, for example, the "test B" button and the "test C" button are used for switching between the two, and the embodiment is not limited in specific form, or, for example, there may be more buttons such as the "test D" button corresponding to more different groups of preset picture parameters, or not limited in specific content of a plurality of different preset picture parameters, where, the preset picture parameters of two different groups may be different in terms of only mode information, may be different in terms of only picture pattern information, or different in terms of a plurality of parameters, and the embodiment is not limited.
In one embodiment, referring to fig. 2, step S5 further includes, for example:
step S51: processing and outputting the 3D test picture to a display screen for display;
Step S53: and outputting a frame synchronization signal corresponding to the 3D test picture to a 3D transmitter, so that the 3D transmitter controls the action of the 3D glasses to enable the picture effect when the 3D test picture is displayed on the display screen based on human vision to be watched, and judging the correctness of the 3D picture display according to the picture effect.
The step S51 and the step S53 are, for example, executed synchronously, and the 3D transmitter is used for controlling the 3D glasses (shutter type) to work, and the frame synchronization signal is used for realizing the synchronization effect of the 3D glasses and the display screen, for example, opening the left eye of the 3D glasses while displaying the left eye screen, closing the right eye, opening the right eye of the 3D glasses while displaying the right eye screen, closing the left eye, and generating the 3D effect by using the visual illusion of the left eye and the right eye.
The principle of the 3D picture display test method provided in the present embodiment is described in detail as follows:
In a normal working state, the display control device receives a video source sent by the upper computer, for example, decodes the video source, then performs 3D display processing according to a video mode, for example, a left-right mode, and outputs a 3D image to the receiving card after processing so as to control the display screen to display a 3D picture. The user can see the 3D effect through 3D glasses (either polarized or shutter type). When the 3D effect is not seen, the user presses the test mode switch, the display screen control device generates a test signal, and executes the steps S1, S3 and S5, wherein the picture pattern of the 3D test picture is, for example, red for the left eye and blue for the right eye (the user can obtain the information through the setting item of the display control device), when the 3D picture processed by the 3D test picture is displayed on the display screen, the user observes the display effect through the 3D glasses, covers the right eye, the picture observed by the left eye is red, covers the left eye, the picture observed by the right eye is blue, and the picture observed by both eyes is purple, so that the 3D test picture is normally displayed, the display control device is judged to be capable of normally controlling the display screen to display the 3D picture, the fault reason comes from the upper computer, and the technician focuses on checking the upper computer. If the 3D display effect cannot be observed, the display control device is indicated to have a fault, and the display control device needs to be checked. It should be noted, however, that if the colors observed by the left and right eyes are merely reversed, and cannot be regarded as "no 3D effect", the test can be repeated after the adjustment is made to the left and right.
The above example is a case when the video mode of the video source is the same as the video mode of the 3D test frame, further for example, the video of the video source is switched to an up-down mode, at this time, if the 3D test frame is still tested according to the left-right mode, if the 3D test frame can normally display the 3D effect, and the failure of the upper computer cannot be determined, the display screen control device may normally process the left-right mode and cannot normally process the up-down mode, at this time, for example, the user may modify the test parameters to adjust the video mode of the 3D test frame to the up-down mode, and if the 3D effect can still be normally displayed, the display control device is normal, and the upper computer is determined to be failed.
Or after the user starts the display control device, the user can directly enter a test mode to test 3D test pictures with video modes of a left mode, a right mode, an up mode, a down mode and a continuous frame mode, and the three modes can be normally displayed and then connected into the upper computer to control the video source sent by the upper computer to be displayed.
Of course, the above only exemplifies the process of manually judging the display effect of the 3D test screen by the user, and the judgment of the display effect of the 3D test screen may be completed by an intelligent device having an image acquisition and recognition function instead of the manual work, and the embodiment is not limited.
According to the embodiment, the local 3D test picture is processed and output for testing the display correctness of the 3D picture based on human eyes, whether the display effect of the 3D test picture is normal or not is judged based on human eyes, so that whether the display control equipment can normally process the 3D picture is judged, the 3D test picture is the local test picture and is not influenced by an upper computer, therefore, the upper computer and the display control equipment can be decoupled, the fault position can be conveniently and rapidly checked, and the efficiency is improved.
