Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, the present disclosure will be described in further detail below with reference to specific embodiments and the accompanying drawings.
It is to be noted that technical terms or scientific terms used in the embodiments of the present disclosure should have a general meaning as understood by one having ordinary skill in the art to which the present disclosure belongs, unless otherwise defined. The use of "first," "second," and similar terms in the embodiments of the disclosure is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
Before specifically describing the method, the system and the display device for identifying and repairing the residual image of the spliced screen provided by the application, an application scenario and an inventive concept of the application are described first.
With an LCD display screen, if it is found that the screen is switched, the previous picture does not disappear immediately, but gradually disappears. This phenomenon is known in the industry as the "afterimage" phenomenon of the display screen; ghosting is a significant residue of the previous picture, which some technicians will also describe as "screen burn". Is the result of driving one point and the other continuously for a long time. The occurrence of the afterimage is caused by the situation that the first picture should disappear and the second picture should appear, but the first picture does not disappear or completely, which affects the visual effect and appearance of the second picture, thereby causing the phenomenon of abnormal display, i.e. afterimage.
The Liquid Crystal (LC) in a TFT (thin film transistor) in a liquid crystal panel is a polar crystalline material that can be twisted by an electric field. The liquid crystal in the thin film transistor must be driven by alternating current. If DC drive is used, the polarity of the crystal will be destroyed. In fact, there is no absolutely symmetrical alternating current; when TFT pixels are driven successively, the associated slight imbalance attracts free ions to the inner electrode, and ions attracted to the inner electrode cause a DC + ac like drive effect. The existing liquid crystal screen usually uses a screen saver when solving the problem of image retention, namely, pixels of the screen display different contents, namely, a mobile screen saver or contents switched at random, thereby avoiding displaying a static picture for more than a certain time.
The scheme provided by the application is based on the technology, and in consideration of the difference between the traditional full screen and the spliced screen, the residual image problem of the spliced screen cannot be eliminated by applying the residual image on the full screen, so that the inventor takes the residual image as the original purpose of the invention and provides the residual image identification and restoration method for the split screen, which is accurate and intelligent, and the realization main body of the residual image identification and restoration method.
In order to solve the problem, an afterimage identification and repair method provided by the embodiment of the disclosure is provided. Fig. 1 shows an exemplary flowchart of an afterimage identification and repair method provided by an embodiment of the present disclosure.
The afterimage identification and restoration method comprises the following steps,
s1: acquiring image information of a display picture of a splicing screen in real time;
as shown in fig. 2, the steps specifically include:
s101: the splicing screen receives and displays actual image information preset by the host;
s102: acquiring each frame of image information displayed by the spliced screen in real time through a camera device; wherein the image information is generated based on the actual image information.
In the step, each frame of image information is acquired and captured in real time through a host camera device and uploaded to a host for recording, the image information is preset on a splicing screen based on the host, the splicing screen displays the image information after receiving actual image information preset by the host, the host carries out trimming and cutting processing on the acquired frame of image information based on the preset actual image information and each frame of image information displayed on the splicing screen at the corresponding moment, and then the splicing screen displays the image information in real time; and acquiring image information displayed by the splicing screen in real time, and comparing the image information with actual image information preset by the host.
S2: identifying sub-image information in each split screen in the image information;
as shown in fig. 3, this step specifically includes,
s201: acquiring a split screen splicing mode of a spliced screen;
s202: based on a split screen splicing mode, cutting image information of a display picture of a splicing screen;
s203: and generating sub-image information by corresponding the clipped image information to each split screen.
In step S201, the host computer presets a split screen connection manner according to specific parameters and specifications of the spliced screen, and if the splicing scheme is preset as 5*5, the number of split screens is 25;
in step S202, the mosaic screen is clipped and trimmed based on the above steps, and a seamless mosaic screen image is obtained.
And the image information is cut according to an image recognition algorithm to be cut, and the sub-image information actually displayed in the split screen of each spliced screen is obtained.
In step S203, the sub-image information displayed by each sub-screen is obtained, and image information composed of sub-screens is generated, where the sub-image information constitutes image information of the mosaic screen, and the sub-image information corresponds to the picture displayed by each sub-screen and jointly constitutes complete mosaic screen image information.
Between the steps S4 and S2, a step S3 may be further included: generating a corresponding image identifier corresponding to each sub-image information;
the steps specifically comprise the steps of,
s301: acquiring a split screen mode of the spliced screen;
s302: generating image identification for the sub-image information of the split screen according to the split screen mode;
and the image identification and the split screen correspond to each other in sequence.
In the above steps, a corresponding identifier is generated for the sub-image information in a split screen mode of the split screen, the identifier may be a number according to a split screen arrangement sequence, the identifier may be an image ID, the split screen is uniquely identified and numbered, the image identifier corresponds to the sub-image information of the split screen one to one, and a split scene is displayed, and the identifier is used for being connected with the host.
S4: comparing the subimage information with preset actual image information;
as shown in fig. 4, this step specifically includes,
s401: acquiring actual image information preset by a host;
s402: acquiring sub-image information displayed in each split screen;
s403: comparing the information of each sub-image with the actual image information of the corresponding position;
s404: generating a primary comparison result;
wherein, the comparison results are the same or different;
in the step 401, the actual image information is the image information preset to the mosaic screen by the host, and is also the real image information to be displayed by the mosaic screen; in step 402, the sub-image information in the split screen is the image information displayed on the split screen, and the sub-image information and the image information should be the same as the actual image information under the condition that the afterimage problem does not occur normally; and then, the comparison step of step 403 is performed to determine whether the sub-image information is the same as the actual image information, if the comparison result is the same, the sub-image information displayed on the split screen represents that the image information to be actually displayed is, then it is determined that the image displayed on the split screen does not have the afterimage phenomenon, otherwise, if the comparison result of the sub-image information is different from the actual image information, the sub-image information displayed on the split screen represents that the image information to be actually displayed is not, then it is determined that the image displayed on the split screen has the afterimage phenomenon and needs to be subjected to afterimage restoration, and the generated primary comparison result is transmitted to the host computer for other processing.
In some optional embodiments, step S4 further includes:
s405: when the primary comparison results are the same, decomposing the sub-image information into a certain number of sub-pictures;
s406: secondarily comparing each sub-picture with the actual image information of the corresponding position;
s407: and generating a secondary comparison result.
In the above steps, the sub-image information in the split screen may be decomposed again, for example, the image information of the first split screen may be decomposed into 16 sub-pictures of 4*4, and corresponding sub-identifiers may be generated, so that the sub-pictures are compared with the actual image information, the position where the afterimage phenomenon occurs may be more accurately located, and the determination is more accurate, and the generated secondary comparison result is transmitted to the host for other processing.
In some optional embodiments, step S4 may further include, on the basis of the foregoing embodiment:
s408: when the secondary comparison results are the same, repeatedly decomposing the sub-picture, and comparing the decomposed sub-picture with the actual image information of the corresponding position until the sub-picture is decomposed into a minimum picture unit;
s409: and after the sub-image information is decomposed into the minimum picture unit, judging that the sub-image information in the split screen has no residual image when the comparison result of the sub-image information and the actual image information is the same.
In this example, the host performs recursive decomposition on the sub-image information one by one according to a certain decomposition coefficient, performs image comparison once for each decomposition until the sub-image information is decomposed to a minimum picture unit, in this example, the minimum picture unit is 1 pixel unit, performs repeated recursive decomposition and compares the minimum picture unit with the image information, determines that the sub-image information in the sub-screen has no afterimage when the comparison result of the sub-image information and the actual image information is the same after the minimum picture unit, sends no afterimage information to the host, and sends the afterimage information to the host if the comparison result is different in the decomposition and comparison processes, and triggers an afterimage elimination command of the host.
S5: and in response to the fact that the sub-image information is different from the corresponding part of the actual image information, extracting the part, which is different from the sub-image information, in the actual image information, and covering the part with the corresponding sub-image information.
As shown in fig. 5, this step specifically includes,
s501: extracting sub-image information with a result different from the actual image information comparison result, and identifying the sub-image information as image information needing to be repaired;
s502: acquiring an identifier of the image information to be repaired;
s503: carrying out recursive decomposition on the identifier based on the sub-picture decomposed by the sub-picture information to generate a sub-identifier;
s504: and refreshing the actual image information to the image information to be repaired through the sub-identifier.
In the above steps, the host computer confirms the image information to be repaired, and extracts the corresponding identifier, if the identifier is in the sub-picture subjected to recursive decomposition, the sub-identifier is extracted, and the corresponding sub-image information identifier is brought out for recognition, and then the sub-identifier is used for refreshing the sub-screen of the image information to be repaired, thereby completing the residual image repairing process.
Example (c): when the split screen is 5 × 5=25, decomposing the whole picture into 25 pieces of sub-image information; then, comparing the picture with the picture cut by the camera in real time by using a picture similarity algorithm, and if complete matching is found, ignoring the picture; if a certain sub-image information identifier is found to be different (the identifier is used for uniquely identifying and numbering a split-screen device, for example, the identifier of the device 1 is the device unique physical address + the number 1, if the numbering continues to be split-screen, the identifier of the sub-screen is the device unique physical address + the number 01 (two digits) + the split-screen unique number (N digits), for example, the physical address +01+001+002+005 is numbered for 4 times of split-screen), recursive decomposition is performed on the identifier, and the decomposition coefficient is a.
Assume ID =3; a =10; that is, the 3 rd sub-picture information is decomposed into 4 × 4=16 sub-pictures, and the 3 rd sub-picture is decomposed into 16 sub-pictures, if some pictures in the 100 sub-pictures are found not to match, the identification of the sub-pictures is recorded, if 100 sub-pictures are found to match, the recursion is continued until the picture is decomposed into 1 pixel. In the process of recursive decomposition, if the comparison result of the arbitrarily appearing sub-pictures is different, namely, the host machine refreshes the image, and the ID picture with unmatched marks is refreshed and displayed in real time, because the afterimage left by the liquid crystal display is not permanent, the afterimage is caused because the window stays at a certain position for too long, the longer the display is opened, the longer the picture stays, and the higher the probability of the phenomenon is. Therefore, the problem of the residual image can be solved through a refreshing mechanism, namely the problem of the residual image can be solved in real time.
In summary, the method for identifying and repairing the residual image of the tiled screen provided by the embodiment can identify the split-screen image information of the tiled screen, and compare and identify the image information on the split-screen with the image information to be actually displayed, so that the residual image is eliminated for the sub-image information on the split-screen which is not in accordance with the actual display information, and the residual image of the tiled screen can be more accurately corresponding to the screen position where the residual image is to be eliminated when the residual image is eliminated.
It should be noted that the method of the embodiments of the present disclosure may be executed by a single device, such as a computer or a server. The method of the embodiment can also be applied to a distributed scene and completed by the mutual cooperation of a plurality of devices. In such a distributed scenario, one of the devices may only perform one or more steps of the method of the embodiments of the present disclosure, and the devices may interact with each other to complete the method.
