[0037] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0038] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0039] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0040] In order to solve the above technical problems, the embodiments of the present disclosure provide a screen correction method, device and projector for a projector. When a correction abnormality is detected in the projector, the user is guided to adjust the projector by displaying an abnormal guidance interface containing guidance information, and then the user is reminded to end the adjustment by displaying an adjustment success interface when the correction abnormality corresponding to the abnormal type is detected to have been resolved. According to the guidance of the abnormal guidance interface, the user can more intuitively and dynamically understand how to adjust the projector in the case of screen correction abnormality, so as to successfully implement automatic or manual screen correction in the future, avoiding the situation that the projector cannot be used due to the inability to implement screen correction, or the screen correction is completed under abnormal circumstances and the correction effect cannot be achieved, and also solving the situation that the user does not know how to solve the correction abnormality problem. In addition, corresponding abnormal guidance interfaces are provided for different abnormal types to make the guidance more targeted, and the adjustment success interface after the adjustment is completed provides the user with more direct adjustment feedback, so that the user has a stronger sense of feedback and certainty in operation, improves the efficiency of abnormality resolution, improves the usability of the product, and reduces the user's understanding cost. In addition, it can reduce the difficulty of setting the projector when it is turned on for the first time and after the state of the projector changes, reduce the probability of user debugging failure, and reduce the return rate.

[0041] like Figure 1 As shown, the image correction method for a projector provided by the embodiment of the present disclosure includes step S101 and step S102, and the method can be applied to a projector.

[0042] In step S101, when a calibration abnormality of the projector is detected, an abnormality guidance interface corresponding to the abnormality type is displayed, and the abnormality guidance interface displays guidance information for guiding the adjustment of the projector, and the guidance information includes at least one of a guidance animation, guidance text and guidance pattern.

[0043] In some embodiments, the guidance information may be used to indicate at least one of an adjustment object, an adjustment method, an adjustment direction, an adjustment amplitude, and an adjustment target. The adjustment object includes a projector, a projection screen, and the like. The adjustment method is used to indicate how to adjust the adjustment object, such as moving or rotating. The adjustment direction is used to indicate the direction in which the adjustment object needs to be moved. The adjustment amplitude may indicate the degree of adjustment. The adjustment target may indicate the target to be achieved after the adjustment.

[0044] Among them, the guiding animation can dynamically guide the user on how to adjust the projector in the form of animation, the guiding pattern can help the user understand how to adjust the projector in the form of a pattern, and the guiding text can guide the user on how to adjust the projector in the form of text. It guides the user by combining dynamic and static methods, with simple expression logic, which reduces the user's understanding cost and improves the usability of the projector.

[0045] In step S102, when it is detected that the correction abnormality corresponding to the abnormality type has been resolved, an adjustment success interface is displayed, in which a success prompt message for reminding the user that the adjustment is successful is displayed. The success prompt message can be text, pictures, etc., and the present disclosure does not limit this.

[0046] In this embodiment, the abnormal guidance interface, the adjustment success interface and the interfaces displayed to the user described below can be displayed to the user through a projection screen, a control screen of a projector, etc., and the present disclosure does not limit this.

[0047] In this embodiment, the projector can perform automatic picture correction after the first power-on or each subsequent power-on, or can also perform automatic picture correction during use under user operation. Among them, automatic picture correction can refer to the automatic detection and correction of geometric distortion and position deviation of the projected picture through the built-in sensors, algorithms and mechanical adjustment mechanisms of the projector, so as to ensure that the projected picture can maintain the correct proportion, clarity and alignment regardless of the installation environment or angle, thereby providing the best visual experience. Correction abnormality can be a correction failure during manual or automatic picture correction due to sensor error, algorithm failure or environmental interference, resulting in image distortion, misalignment or inability to align, that is, correction abnormality refers to the inability of the projector to complete picture correction (picture correction failure) due to abnormal conditions, and the user needs to intervene manually to adjust the projector.

[0048] In some embodiments, the method may include: during the automatic picture correction process, determining whether the projector has a correction abnormality according to the current state data of the projector, and if it is determined that the projector has a correction abnormality, further determining the abnormality type according to the current state data of the projector. Then, generating a corresponding abnormality guidance interface according to the abnormality type and the current state data of the projector, and then displaying the abnormality guidance interface to the user.

[0049] Among them, the current status data of the projector may include at least one of the following: the current projection distance, posture, projection angle of the projector, the projection screen image obtained by the camera of the projector shooting the projection screen, and the occlusion detection result obtained by the projector detecting the occlusion with the camera.

[0050] The projection distance is also called the transmission distance, which is the distance between the projector and the projection screen. The projection screen can be a wall, a curtain, etc. for projection, and the present disclosure does not limit this. The projection distance is within the distance range [s1, s2] set by the projector to ensure that the normal and undistorted picture is displayed to the user after automatic or manual correction of the picture. Different projectors have a pre-set distance range, for example, the distance range can be 1.5m to 3m.

[0051] The posture of the projector may be the posture of the projector relative to the horizontal direction, and may include a deflection angle θ1 relative to the horizontal direction, a deflection angle θ2 relative to the vertical direction, etc., which is not limited in the present disclosure. The posture of the projector is within the deflection angle range set by the projector to ensure that a normal and undistorted image is displayed to the user after automatic or manual correction of the image. Different projectors have a pre-set deflection angle range, which is not limited in the present disclosure.

[0052] The projection angle may be the angle between the camera of the projector and the projection screen, which includes a first angle α1 in the horizontal direction between the center line of the camera and the plane where the projection screen is located, and a second angle α2 in the vertical direction between the camera and the plane where the projection screen is located. The horizontal direction of the plane where the projection screen is located may be represented by: any straight line parallel to the straight line where the horizontal frame of a framed projection screen such as a curtain is located, and any straight line in the plane where the projection screen is located that is parallel to the ground. The vertical direction of the plane where the projection screen is located may be represented by any straight line perpendicular to the plane where the projection screen is located. The first angle and the second angle of the projector are respectively within the preset angle range to ensure that the picture of the projector can display a normal and undistorted picture to the user after automatic or manual correction of the picture. Different projectors have pre-set angle ranges corresponding to the first angle and the second angle, respectively, and the present disclosure does not limit this.

[0053] In some embodiments, the abnormality type of the correction abnormality may include any of the following: distance type, screen coverage type, projection angle type, horizontal tilt type, camera occlusion type. In this way, the user can more intuitively understand which aspects of the projector need to be adjusted through classification, which is convenient for the user to understand.

[0054] Among them, the calibration anomaly of the distance type may mean that the current projection distance s of the projector is too far or too close, that is, The projection distance can be detected by a device capable of distance detection, such as an infrared sensor or a ToF sensor (Time of Flight sensor, also called a time of flight sensor) provided in the projector.

[0055] The correction anomaly of the projection angle type may mean that at least one of the first angle α1 and the second angle α2 is not within the preset angle range, that is, and / or The projection angle may be determined based on detection data of devices such as a gyroscope and a distance detection device provided in the projector.

[0056] The correction anomaly of the horizontal tilt type may mean that the deflection angle θ1 of the projector relative to the horizontal direction is not within the corresponding angle range, that is, The deflection angle θ1 of the projector relative to the horizontal direction can be detected by a device such as a level meter provided in the projector.

[0057] The correction anomaly of the screen coverage class may refer to that the projection screen does not cover the four frames of the projection screen with detectable frames such as a curtain. The projector can control the camera to capture the image to determine whether the projection screen covers the projection screen according to the projection screen image obtained by the capture. Among them, for projection screens with frames such as curtains, it is necessary to detect the correction anomaly of the screen coverage class, while for projection screens without frames such as walls, it is not necessary to detect the correction anomaly of the screen coverage class. Therefore, the projector can first determine whether the current projection screen is a projection screen with a frame such as a curtain, and then determine whether to detect the correction anomaly of the screen coverage class. In some embodiments, the projector can determine that the current projection screen is a projection screen with a frame such as a curtain when it is detected that it has been paired and connected to the projection screen, and there is a partial frame in the projection screen image, and then determine that it is necessary to detect the correction anomaly of the screen coverage class. The projector can determine that the current projection screen is a projection screen without a frame such as a wall when it has not been detected that it has been paired and connected to the projection screen, and there is no frame in the projection screen image, and then determine that it is not necessary to detect the correction anomaly of the screen coverage class.

[0058] The calibration anomaly of camera occlusion may refer to stains on the camera of the projector or obstruction in front of the camera. The projector itself can determine whether the projector has a calibration anomaly of camera occlusion through the occlusion detection result obtained by the occlusion detection. Among them, the projector can detect the obstruction in at least one of the following ways to obtain the occlusion detection result: through the infrared sensor set by itself, the infrared sensor performs the obstruction detection on the projection field to obtain the occlusion detection result; controls the camera to shoot the projection screen to obtain the screen image, and then performs the obstruction detection on the screen image to obtain the occlusion detection result, etc., and the present disclosure does not limit this.

[0059] In this embodiment, under different abnormality types, the guidance information to be displayed in the abnormality guidance interface is different, so that the user can more intuitively understand how to adjust the projector. Figure 2-Figure 6The abnormal guidance interface shown is schematically illustrated.

[0060] like Figure 2 As shown, if the abnormality type is distance type and the projection distance s is greater than s2, the guidance text that can be displayed in the abnormal guidance interface is "Please move the projector closer to the wall" (adjustment object and adjustment method), "The correction effect is best within 1.5 to 3 meters" (adjustment target). Among them, the guidance pattern includes a depth or perspective schematic line (blue dotted line) located in the center of the interface, and the guidance animation includes a directional arrow animation (adjustment direction) that reminds the user to move the projector closer to the wall or other projection screens. On the contrary, if the abnormality type is distance type and the projection distance s is less than s1, the guidance text that can be displayed in the abnormal guidance interface is "Please move the projector farther from the wall" and "The correction effect is best within 1.5 to 3 meters". Among them, the guidance pattern includes a depth or perspective schematic line located in the center of the interface, and the guidance animation includes a directional arrow animation that reminds the user to move the projector away from the wall or other projection screens.

[0061] like Figure 3 As shown, if the abnormal type is screen coverage, the guidance text that can be displayed in the abnormal guidance interface is "Please move the device" (adjustment object and adjustment method), "Let the projected image completely cover the four borders of the screen" (adjustment target). Among them, the guidance animation can include a directional arrow animation that reminds the user to move the projector (adjustment direction).

[0062] like Figure 4 As shown, if the abnormality type is the projection angle type and the first angle α1 is greater than α12, the guidance text that can be displayed in the abnormal guidance interface is "Please adjust the projection angle to the left" (adjust the direction and adjust the object), "Try to straighten the projector" (adjust the target). Among them, the guidance pattern includes a center schematic line (blue dotted line) located in the center of the interface, and the guidance animation includes a direction arrow animation that reminds the user to move the projector to the left (adjust the direction). Conversely, if the abnormality type is the projection angle type and the first angle α1 is less than α11, the guidance text that can be displayed in the abnormal guidance interface is "Please adjust the projection angle to the right" and "Try to straighten the projector". Among them, the guidance pattern includes a center schematic line located in the center of the interface, and the guidance animation includes a direction arrow animation that reminds the user to move the projector to the right.

[0063] like Figure 5 As shown in the figure, if the abnormality type is horizontal tilt, the guidance text that can be displayed in the abnormality guidance interface is "Please adjust the horizontal angle" (adjustment object) and "The angle tilt is recommended not to exceed 15 degrees" (adjustment target). Among them, the guidance pattern includes the current horizontal center schematic line of the projector (red dotted line) and the horizontal center schematic line to which the projector needs to be adjusted (blue dotted line). The angle between the two center lines indicates the adjustment range, and the guidance animation includes a directional arrow animation to remind the user to turn the projector (adjustment direction).

[0064] like Figure 6 As shown, if the abnormal type is camera blocking, the guidance text that can be displayed in the abnormal guidance interface is "Is the camera blocked?", "Please check whether the front of the camera is blocked or has stains" (adjustment method). In some embodiments, such as Figure 6 As shown, the abnormal guidance interface may also include an unobstructed control, and the unobstructed control may also have a text prompt of "I have confirmed that the camera is unobstructed". When a trigger operation for the unobstructed control is detected, it is determined that the user has removed the camera obstruction, and the camera obstruction type abnormality no longer exists.

[0065] In some embodiments, the method may further include: adjusting the guidance information displayed in the abnormal guidance interface in response to the current status data of the projector. Since the user may over-adjust or adjust too little during the process of adjusting the projector based on the abnormal guidance interface, or may introduce other types of abnormalities during the adjustment process, it is possible to determine what kind of adjustments the projector needs to make after the user adjusts the projector in real time based on the current status data, and then adjust the guidance information displayed in the abnormal guidance interface. For example, displaying Figure 5 The abnormal guidance interface shown in the figure, but because the user adjusts too much to the left, the first angle α1 is smaller than α11, then the displayed Figure 5 The abnormal guidance interface shown is replaced by Figure 6 The abnormal guidance interface shown allows the user to adjust the projector in time.

[0066] In some embodiments, the method may further include: when a calibration anomaly is detected in the projector, issuing a guiding voice, wherein the content of the guiding voice matches the guiding information displayed in the abnormal guiding interface. In this way, the guiding voice can assist in guiding the user to move the projector. For example, the guiding voice may be a voice corresponding to the guiding text displayed in the abnormal guiding interface, and the present disclosure does not limit this.

[0067] In some embodiments, since the calibration anomaly detected by the projector may include at least one of the above-mentioned anomaly types, when it is detected that the projector has a calibration anomaly and there are multiple types of anomalies, one of the anomaly types may be selected to generate the guidance information required to be displayed on the anomaly guidance interface, and then the anomaly guidance interface is displayed to the user and the subsequent step S102 is executed, and after step S102, it is re-determined whether there is a calibration anomaly, and if there is a calibration anomaly, the above process is repeated until the projector is adjusted to meet the image calibration requirements.

[0068] In some embodiments, the content of the adjustment success interface displayed after the abnormal guidance interface may be correlated with the guidance information displayed in the abnormal guidance interface, so that it is convenient to remind the user that he has successfully completed the adjustment of which type of correction abnormality of the projector. In some embodiments, the interface features of the abnormal guidance interface and the adjustment success interface may be different; the interface features include at least one of the following: border, background. The different interface features can make it easier for the user to intuitively distinguish whether the displayed abnormal guidance interface is the adjustment success interface through the interface, and it is easier for the user to determine whether the adjustment is successful through the clear changes in the interface features after successfully adjusting the projector. Among them, the difference in interface features can be reflected in the following ways: different colors, shapes, etc. of the borders, different colors, patterns, etc. of the backgrounds, and the present disclosure does not limit this.

[0069] Correlation can be reflected in the fact that two interfaces contain the same display elements or interface features. Display elements include patterns, colors, text, etc. For example, Figure 2 The abnormal guidance interface shown and the adjustment success interface shown later both display blue schematic lines. Figure 4 The abnormal guidance interface shown in FIG. 5 and the adjustment success interface shown thereafter both display a center schematic line (blue dotted line), and the abnormal guidance interface shown in FIG. 5 and the adjustment success interface shown thereafter both display a horizontal center schematic line (blue dotted line), which reflect the correlation between the two interfaces. Figure 2 , Figure 3 The abnormal guidance interface shown has a red border, and the adjustment success interface shown later has a blue border. Figure 4 The abnormal guidance interface shown has a partial red area in the background, and the adjustment success interface displayed later has a partial blue area in the background, and the position of the area is the same as the red area in the abnormal guidance interface. The different border colors and background colors make it easy for users to determine whether the adjustment is successful through interface changes.

[0070] In some embodiments, the method may further include: when it is detected that the correction anomaly corresponding to the anomaly type has been resolved, issuing an adjustment success voice and / or adjustment success prompt tone. In this way, the user can be provided with an all-round visual and auditory reminder based on the adjustment success interface, adjustment success voice, and adjustment success prompt tone, so that the user can determine that the adjustment has been successful through the adjustment success voice and / or adjustment success prompt tone when the user cannot see the interface content in time (for example, when adjusting the projector with the back to the projection screen).

[0071] The successful adjustment voice may be a voice corresponding to the abnormal type that is successfully adjusted, for example, the successful adjustment voice may be a voice corresponding to the successful prompt information in the successful adjustment interface being displayed, and the present disclosure does not limit this. The successful adjustment prompt sound may be a pre-set sound effect, and the successful adjustment prompt sounds issued by different successful adjustment interfaces may be the same or different, and the present disclosure does not limit this.

[0072] In some embodiments, the method further includes: upon detecting that the projector is adjusted to meet the image correction requirement, Figure 2-Figure 5 As shown, an automatic correction prompt is displayed in the adjustment success interface, and the automatic correction prompt is used to remind the user to automatically calibrate the adjusted projector. Then, if it is determined that automatic correction is required according to the user's response to the automatic correction prompt, the picture is automatically corrected.

[0073] Among them, Figure 2-Figure 5 As shown, the automatic correction prompt may be a control, and if a trigger operation for the control is detected, it may be determined that automatic correction is required, and then the image is automatically corrected. Figure 2-Figure 5 As shown, the automatic correction prompt also displays a countdown for the automatic start of automatic correction. If no other operation issued by the user is detected before the countdown is completed, it can be determined that automatic correction is required, and then the picture is automatically corrected.

[0074] Among them, automatic image correction can refer to the automatic detection and correction of the geometric distortion and position deviation of the projected image through the projector's built-in sensors, algorithms and mechanical adjustment mechanisms, to ensure that the projected image maintains the correct proportion, clarity and alignment regardless of the installation environment or angle, thereby providing the best visual experience.

[0075] In some embodiments, Figure 7 As shown, the method may further include: in the case of determining that the automatic correction of the image fails, displaying an automatic correction failure interface, wherein the automatic correction failure interface displays at least one of the following: a prompt for automatic correction again, a prompt for manual correction, and a prompt for projector adjustment.

[0076] The projector adjustment prompt is used to remind the user to readjust the projector. For example, the projector adjustment prompt can be Figure 7 "Please adjust the projection distance, angle, and do not block the camera."

[0077] In some embodiments, after the automatic correction failure interface is displayed to the user, in response to the user performing an adjustment operation (e.g., moving the projector, adjusting the projector angle, removing obstructing objects, etc.), an abnormality guidance interface corresponding to the abnormality type may be displayed until the adjustment is successful. Alternatively, in response to the user triggering a control or button for displaying the abnormality guidance interface, or a user issuing a shortcut operation for displaying the abnormality guidance interface, the abnormality guidance interface may be displayed. Alternatively, the abnormality guidance interface may be automatically jumped to after a preset time period after the automatic correction fails.

[0078] The embodiment of the present disclosure also provides a screen correction device for a projector, the device comprising:

[0079] An abnormality guidance interface display module is used to display an abnormality guidance interface corresponding to the abnormality type when a calibration abnormality of the projector is detected, wherein the abnormality guidance interface displays guidance information for guiding the adjustment of the projector, and the guidance information includes at least one of a guidance animation, a guidance pattern, and a guidance text;
