Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The terms "first," "second," and the like in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
First, a projection method is proposed in the present application, fig. 1 is a schematic flow chart of a first embodiment of the projection method in the present application, and as shown in fig. 1, the projection method may include:
step S11: the projection picture has a viewing obstacle, and the current playing time node on the progress bar is obtained to obtain a first time node.
The projection picture may be a picture projected by the projection device based on the received image signal, and the image signal may be a video signal or another type of play signal, which is not limited herein. The progress bar is a playing progress bar corresponding to the image signal, and the first time node is a time node on the progress bar corresponding to the situation that the projection picture of the image signal is monitored to have a viewing obstacle, namely, the first time node is a time node for describing the playing progress of the image signal.
When the projection picture has a viewing obstacle, the user cannot normally view the normal image corresponding to the image signal from the projection picture, that is, the projection picture which the user views at the moment is not the projection picture which is normally projected based on the image signal.
The projection method can be applied to projection equipment, and the state of a projection picture can be monitored by a preset monitoring mode. When the projection picture is monitored to have a viewing obstacle, a current playing time node corresponding to the playing progress of the image signal at the moment in a playing progress bar corresponding to the image signal can be obtained, and the current playing time node is determined to be a first time node.
Optionally, the projection method may further include:
and when the projection picture is abnormal or the projection equipment corresponding to the projection picture receives a system operation instruction, judging that the projection picture has a viewing obstacle.
Specifically, when an abnormality occurs in a projection screen of an image signal, there may be a distortion, a loss, a frame loss, or the like of the screen on the projection screen that the user views, so that the user cannot view the projection screen that the user would normally view based on the image signal. When the projection device corresponding to the projection picture receives the system operation instruction, a system menu corresponding to the system operation instruction may appear on the projection picture, where the system menu is used for the user to perform related system operation, and at the same time, the user cannot watch the corresponding projection picture that should be seen based on the image signal under normal conditions. Based on the analysis, when the projection picture of the image signal is abnormal and/or the projection equipment corresponding to the projection picture receives the system operation instruction, the user cannot normally observe the image, so that it can be determined that the image is in disorder on the projection picture of the image signal.
Further, the projection method further includes a step of determining that an abnormality occurs in the projection screen, and when it is determined that the projection screen has a viewing obstacle, the projection method further includes:
and the projection picture is restored to be normal, and the film watching obstacle is eliminated.
The projection method further comprises the step that the projection equipment corresponding to the projection picture receives a system operation instruction, and when the projection picture is judged to have a viewing obstacle, the projection method further comprises the following steps:
and finishing the system operation corresponding to the system operation instruction, and judging that the film watching barrier is eliminated.
If an abnormality occurs in the projection screen, and the projection device corresponding to the projection screen receives the system operation instruction, the projection screen is restored to be normal, and the system operation corresponding to the system operation instruction is completed, so that it is determined that the viewing obstacle is eliminated.
Specifically, based on the above manner, whether there is an abnormality caused by the non-subjective intention of the user or a system menu shielding phenomenon caused by the subjective intention of the user exists on the projection picture, it is determined that the projection picture has a viewing obstacle, and further it is determined when the viewing obstacle is eliminated, so that the step S12 is triggered to perform corresponding processing, and the possibility that the user misses useful information in the projection picture is further reduced by the determination logic of whether the viewing obstacle exists, thereby improving the user experience.
Optionally, step S11 may specifically include:
the projection picture has a viewing obstacle, the current playing time node on the progress bar is obtained to obtain a first time node, and the projection picture is stopped from being played.
Specifically, based on the mode, the user can avoid watching the projection picture with any viewing obstacle, and the overall viewing quality of the user is further improved.
Optionally, step S11 may specifically include:
the projection picture has a viewing obstacle, the current playing time node on the progress bar is obtained to obtain a first time node, and the projection picture is continuously played.
Specifically, based on the above manner, when the projection picture has a viewing obstacle, the projection picture can be continuously played. The projection picture is provided with a viewing obstacle, but the viewing obstacle does not always lead to the total loss of useful information corresponding to the projection picture, so that based on the mode, when the projection picture is abnormal, a user can continuously watch the projection picture, and further, the user can acquire part or all of useful information before the viewing obstacle in the projection picture is eliminated, the timeliness of the useful information acquired by the user is ensured, and the experience of the user is improved.
Step S12: the viewing obstacle is eliminated, and the projection picture is played from the second time node on the progress bar.
The second time node is the first time node or the time node before the first time node, and similarly, the second time node is also the time node for describing the playing progress of the projection picture.
When the above-mentioned preset monitoring mode detects that the viewing obstacle in the projection picture has been eliminated, the projection picture corresponding to the second time node in the playing progress bar can be played, so that the user can watch the projection picture which cannot be watched before because of the existence of the viewing obstacle, and the user can acquire all information in the projection picture, and the user experience is improved.
For example, if a projection picture of a video with a total playing progress of 60 minutes can be played based on the image signal, in practice, when it is monitored that the projection picture has a viewing obstacle, the playing progress of the playing progress bar corresponding to the image signal may be at the 30 th minute and the 0 th second, that is, the current playing time node of the progress bar when the projection picture has the viewing obstacle is the 30 th minute and the 0 th second, and the current playing time node is recorded as the first time node.
The second time node may be the first time node, or may be a time node located before the first time node on the playing progress bar, where it is assumed that the second time node is 29 th minute and 59 th second, when it is detected that the viewing barrier of the projection image is eliminated, the video corresponding to the image signal may be played from the 29 th minute and 59 th second of the playing progress bar corresponding to the image signal, so as to avoid the user missing part of the projection image, and improve the user experience.
Optionally, the second time node is earlier than the first time node by a preset time period, wherein the preset time period is greater than or equal to 0.
Specifically, the preset time period may be any one of 1 second, 2 seconds, 3 seconds and other time periods, which may be specifically determined according to actual requirements.
It should be noted that, after the projection screen is in the viewing obstacle, the projection device or the related detection device on the projection device may take a certain period of time to detect the condition, so the obtained first time node may be later than the actual time node when the projection screen is in the viewing obstacle.
Thus, to compensate for the delay time period between the occurrence of the viewing disorder and the time node at which the viewing disorder is detected, the second time node may be set to a time node that is a preset time period earlier than the first time node, instead of directly setting the second time node to the first time node. Based on this, after the projection picture is played from the second time node on the progress bar, it is ensured that the projection picture actually played covers the target projection picture, wherein the target projection picture is all pictures which cannot be normally watched due to the existence of the viewing obstacle in the projection picture.
Based on the mode, the possibility that the user misses useful information in the projection picture can be further reduced, and the user experience is improved.
Further, step S12 may specifically include:
and eliminating the viewing obstacle, acquiring a first user instruction, and determining that the preset duration is 0 or a preset value based on the first user instruction.
Specifically, the user may be queried to obtain the first user instruction, and based on the first user instruction, it may be known whether the user needs to make up for the delay time period, and further it may be determined whether the preset time period is set to 0 or to a preset value, where the preset value may be any one of 1 second, 2 seconds, 3 seconds, and other time periods. Based on the above mode, whether the second time node is set as the first time node or the time node before the first time node can be determined according to the wish of the user, so that the experience of the user is improved.
Optionally, step S12 may specifically include:
and eliminating the viewing obstacle, acquiring a second user instruction, and determining whether the user needs to perform compensation playing or not based on the second user instruction.
The user needs to make compensation play, and the projection picture is played from the second time node on the progress bar
The user does not need to carry out compensation playing and continues to play the projection picture.
Specifically, the user can be queried to obtain the second user instruction, so that whether the user needs to perform compensation playing or not can be known, namely whether the user needs to watch the projection picture which cannot be normally watched due to the existence of the viewing obstacle in the projection picture or not, if the user does not need to be determined based on the second user instruction, the projection picture can be continuously played at the current time node on the progress bar at the moment, and the image does not need to be played from the second time node on the progress bar, so that the user experience is improved.
Compared with the prior art, when the projection picture has the viewing obstacle, the time node on the progress bar is recorded as the first time node, and when the viewing obstacle in the projection picture is eliminated, the projection picture starts to be played from the second time node on the progress bar, and as the second time node is the first time node or the time node before the first time node, the user can watch the projection picture after the first time node again, so that any useful information in the projection picture is prevented from being missed, and the experience of the user is improved.
The present application further provides a projection method, which includes steps S11-S12 described in the first embodiment, and will not be described herein.
Fig. 2 is one of flow diagrams of a second embodiment of the projection method of the present application, as shown in fig. 2, where the projection method further includes:
step S21: and (5) judging that the projection picture is abnormal and has a viewing obstacle.
Step S22: and the projection picture is restored to be normal, and the film watching obstacle is eliminated.
Fig. 3 is a second schematic flow chart of a second embodiment of the projection method of the present application, as shown in fig. 3, where the projection method further includes:
step S31: and at least one of the first preset condition, the second preset condition and the third preset condition is met, and the projection picture is judged to be abnormal.
The first preset condition comprises that an image signal corresponding to the projection picture of the projection equipment is normal and the projection picture is abnormal, the second preset condition comprises that the projection picture is abnormal due to the fact that the image signal is abnormal, and the third preset condition comprises that the projection picture is abnormal due to the fact that the projection equipment is faulty.
The following is a specific description of the abnormality of the projection screen caused by the normal operation of the projection device and the image signal, the abnormality of the projection screen caused by the abnormal operation of the image signal, and the abnormality of the projection screen caused by the failure of the projection device:
first, the projection device and the image signal are normal, and the projection screen is abnormal.
Under the condition that the projection equipment is normal and the image signal played by the projection equipment is normal, the projection picture can be obtained, the image information of the obtained projection picture is subjected to image analysis, whether the projection picture is abnormal or not is determined, and whether the projection picture is abnormal or not can be further determined through the image analysis.
For example, even if the projection device and the image signal are normal, if the projection device or the corresponding projection screen corresponding to the projection picture is displaced, or if a foreign object is present to block the projection device, the projection picture is abnormal, such as picture deformation, blurring, incompleteness, etc.
The light projected by the projection device is image light, and the image light needs to be projected on a carrier to form the projection picture, wherein the carrier can be a projection curtain, a wall, or other types of carriers, not limited herein, and the image light can be any type of light, specifically, the image light can be determined according to actual needs, and is not limited herein.
Such an abnormality of the projection screen can be detected by an image acquisition device and an image analysis device provided on the projection apparatus. When such an abnormality of the projection screen occurs on the projection screen, it is possible to determine that the projection device and the image signal are normal and the projection screen is abnormal.
Second, there is an abnormality in the image signal, which causes an abnormality in the projection screen.
The method can determine whether the image signal is complete or not by detecting the data integrity of the image signal received by the projection equipment, and further can judge whether the image signal is abnormal or not.
For example, after the data integrity of the image signal received by the projection device is detected, if the detection result is incomplete, it may be determined that the image signal is abnormal, and if the projection screen is detected to be abnormal, it may be determined that the image signal is abnormal, so that the projection screen is abnormal.
Third, there is a malfunction with respect to the projection apparatus, which causes an abnormality in the projection screen.
By detecting each component in the projection equipment, whether the projection equipment has a fault component or not can be determined, and whether the projection equipment has a fault or not can be further judged.
For example, after detecting each component in the projection device, when a faulty component exists, it may be determined that the projection device has a fault, and if an abnormality in the projection screen is detected at this time, it may be determined that the projection device has a fault, which results in an abnormality in the projection screen.
If the projection device has a fault, the projection picture of the corresponding projection picture is abnormal, and whether the projection picture is abnormal or not can be determined based on the projection picture and the image signal. However, in a case where there is a failure in the projection apparatus, an abnormality occurring in the projection screen may be relatively small, for example, the entire brightness of the projection screen is uneven, so that the brightness of a part of the screen is slightly high and the brightness of a part of the screen is slightly low, and in a case where the difference between the brightness of the two parts is small, it is difficult to detect the abnormality by detecting the projection screen of the projection screen. Therefore, fault detection is directly carried out on each component in the projection equipment to determine whether the projection picture is abnormal or not, and the method is accurate.
Step S32: and the projection picture is restored to be normal, and the film watching obstacle is eliminated.
After the projection picture is judged to be abnormal, maintenance personnel can be waited or informed to carry out maintenance processing, and the specific conditions are as follows:
firstly, if the first preset condition is detected to be met, that is, after the projection equipment and the image signal are judged to be normal and the projection picture is abnormal, the projection equipment can be controlled to automatically adjust projection parameters (such as parameters of focal length and the like) or related personnel can be informed to clear a shielding object blocking the projection equipment to project so as to enable the projection picture to be restored to be normal.
Optionally, the projection method may further include:
the projection device and the image signal are normal, and the projection picture has at least one of abnormality of picture defocus, picture deformation and picture deletion, and the projection picture is judged to be normal and abnormal due to the normal of the projection device and the image signal.
Specifically, when at least one of the projection screen is abnormal, such as out-of-focus, distortion, and missing, it may be determined that the projection screen is abnormal, that is, the first preset condition is satisfied at this time, and it may be further determined that the projection screen is abnormal. Then, the maintenance processing corresponding to the first preset condition is needed to restore the projected image to be normal.
In addition, the projection device and the image signal may be normal, and the projection image may have one or more of other types of image anomalies, so that it is determined that the projection device and the image signal are normal and the projection image is abnormal, which may be determined according to the actual requirement, and is not limited herein.
Secondly, if the condition that the image signal meets the second preset condition is detected, namely, after the condition that the image signal is abnormal and the projection picture is abnormal is judged, the projection equipment can be controlled to restore the data of the received image signal, or the communication connection with the image signal transmitting source is built again to receive the image signal, or related personnel are informed to conduct data checking, so that the projection picture is expected to be restored to be normal.
Optionally, the projection method may further include:
the image signal is incomplete in data and the projection picture is abnormal, and the image signal is judged to be abnormal, so that the projection picture is abnormal.
Specifically, when the data of the image signal is incomplete and the projection screen is abnormal, it can be determined that the projection screen is abnormal due to the presence of the abnormality of the image signal. Then, the maintenance processing corresponding to the second preset condition is needed to restore the projected image to be normal.
In addition, one or more of other types of signal anomalies may be used, and the projection image is abnormal, so that it is determined that the image signal is abnormal and the projection image is abnormal, which may be determined according to the actual requirement, and the method is not limited herein.
Thirdly, if the third preset condition is detected to be met, namely, after the projection equipment is judged to have faults and the projection picture is abnormal, the projection equipment can be controlled to carry out self-checking or related personnel are informed to detect the projection equipment, so that the reason of the fault of the projection equipment is checked and repaired, and the projection picture is expected to be recovered to be normal.
Optionally, the projection method may further include:
and judging that the projection equipment has faults and the projection picture is abnormal due to the fact that the fault component exists in the target class component and the projection picture is abnormal.
The target class component is a component which can influence the projection picture in the projection equipment corresponding to the projection picture. There are many components in the projection apparatus, and there are some components that do not affect the projection screen even if they fail, such as a time-on/off component, etc.
The target class component may include at least one of a light source, a processor, a signal receiving component, etc., without limitation herein.
Specifically, when there is a faulty component in the target class component and the projection screen is abnormal, it may be determined that the projection screen is abnormal due to the faulty projection apparatus. Then, the maintenance processing corresponding to the third preset condition is needed to restore the projected image to be normal.
Compared with the prior art, when the projection picture has the viewing obstacle, the time node on the progress bar is recorded as the first time node, and when the viewing obstacle in the projection picture is eliminated, the projection picture starts to be played from the second time node on the progress bar, and as the second time node is the first time node or the time node before the first time node, the user can watch the projection picture after the first time node again, so that any useful information in the projection picture is prevented from being missed, and the experience of the user is improved.
The present application further provides a projection method, which includes steps S11-S12 described in the first embodiment, and will not be described herein.
Fig. 4 is a schematic flow chart of a third embodiment of the projection method of the present application, as shown in fig. 4, where the projection method further includes:
step S41: and the projection equipment corresponding to the projection picture receives the system operation instruction and judges that the projection picture has a viewing obstacle.
The system operation instruction may be an information viewing instruction, a resolution adjustment instruction, or a signal menu instruction, where when the projection device receives the instruction, the projection device generally pops out a corresponding information picture in the projection picture, so that a user can perform relevant setting according to the corresponding information picture, at this time, the menu picture will block the projection picture that is being played originally, so that the user cannot view the normal projection picture, and therefore, it can be determined that the projection picture has a viewing obstacle, and normal viewing of the user is affected.
In addition, the system operation instructions may be other types of projection device control instructions, which are not limited herein.
Step S42: and finishing the system operation corresponding to the system operation instruction, and judging that the film watching barrier is eliminated.
When the system operation instruction is an information viewing instruction, after the projection equipment receives the information viewing instruction, an information picture related to the image signal is displayed on the projection picture so as to be used for viewing related information by a user. When the disappearance of the information picture is monitored and the content picture corresponding to the playing image signal is returned, the operation corresponding to the information viewing instruction can be considered to be completed, and the elimination of the viewing obstacle can be judged.
When the system operation instruction is a resolution adjustment instruction, after the projection equipment receives the resolution adjustment instruction, a setting menu screen for adjusting the resolution of the projection screen is displayed on the projection screen, so that a user can adjust the resolution. When the disappearance of the setting menu picture is monitored and the content picture corresponding to the playing image signal is returned, the operation corresponding to the resolution adjusting instruction can be considered to be completed, and the elimination of the viewing obstacle can be judged.
When the system operation instruction is a signal menu instruction, after the projection equipment receives the signal menu instruction, an image signal menu page is displayed on a projection picture so as to enable a user to perform relevant setting of image signals. When the disappearance of the menu page of the image signal is monitored and the content picture corresponding to the playing image signal is returned, the operation corresponding to the signal menu instruction can be considered to be completed, and the elimination of the viewing obstacle can be judged.
Based on the mode, the situation that the user misses part of the projection picture of the image signal due to related operation of the projection equipment can be avoided, and the user experience is improved.
Compared with the prior art, when the projection picture has the viewing obstacle, the time node on the progress bar is recorded as the first time node, and when the viewing obstacle in the projection picture is eliminated, the projection picture starts to be played from the second time node on the progress bar, and as the second time node is the first time node or the time node before the first time node, the user can watch the projection picture after the first time node again, so that any useful information in the projection picture is prevented from being missed, and the experience of the user is improved.
The present application further proposes a projection system, fig. 5 is a schematic structural diagram of an embodiment of the projection system of the present application, as shown in fig. 5, where the projection system 50 may include: a projection module 51, an identification module 52 and a control module 53.
