[0078] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the embodiments described in the text are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

For the purpose of simplifying the present application, the components and settings of specific examples are described in the text below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0080] In order to solve the technical problem that the area adjusted by the method for adjusting the brightness of a monitoring picture in the prior art does not match the area of user interest, thereby resulting in an unsatisfactory adjustment effect on the area of user interest and affecting user experience, the present application provides a method, device, electronic device and system for adjusting the brightness of a monitoring picture, which can determine the target area of user interest according to the triggering operation of the user on the monitoring picture, and then adjust the brightness of the target area according to the current brightness of the target area after the current brightness of the target area is collected, so as to separately adjust the monitoring area of user interest, thereby realizing the targeted brightness adjustment on the monitoring area of user interest, improving the brightness adjustment effect on the monitoring picture, and improving user experience.

[0081] The brightness adjustment method of a monitoring picture provided by the present application will be further explained and described below with reference to the drawings and specific embodiments, and the embodiments do not constitute a limitation on the embodiments of the present application.

[0082] Referring to FIG. 1, an embodiment flowchart of a brightness adjustment method of a monitoring picture is provided in the present application. As an embodiment, the flowchart shown in FIG. 1 can be applied to a terminal device, which can be connected to a monitoring device (for example, a camera), and the monitoring device can be used to monitor a preset area. As shown in FIG. 1, the flowchart can include the following steps:

[0083] Step 101: Obtain a monitoring picture of a preset area by a monitoring device, and display the monitoring picture.

[0084] Step 102: In a case where a triggering operation for the monitoring picture is received, determine a corresponding triggering position of the triggering operation in the monitoring picture.

[0085] The following describes steps 101 and 102:

[0086] The monitoring device refers to a device with a monitoring function, that is, a device capable of collecting images of a preset area in real time, for example, a camera.

[0087] The monitoring picture refers to a picture of a preset area collected by the monitoring device.

[0088] In an embodiment, the execution subject of the present application can be a terminal device, which can be connected to a monitoring device. Based on this, the terminal device can obtain a monitoring picture of a preset area by a monitoring device in real time, and display the monitoring picture through a visual interface. The terminal device can be a mobile terminal, for example, a mobile phone, or a computer display terminal, for example, a desktop computer, and the present application does not limit this.

[0089] On this basis, a user can remotely monitor a preset area through the monitoring picture displayed by the terminal device. In actual application, when there is uneven distribution of light, brightness, etc. in the preset area (for example, at night, due to the position of the lighting device, there can be a situation that part of the area is dark or part of the area is too bright in the preset area), it is easy to cause part of the monitoring picture to be unclear. At this time, if the user wants to view the situation in the area, the user cannot understand the part of the area through the monitoring picture.

[0090] To this end, when a user views a monitoring picture, if the user wants to view a specific area in the monitoring picture, the user can trigger an operation on a focus point of the area, and the triggering operation can include clicking, double-clicking, or long pressing, etc. Further, in order to prevent misoperation, the triggering operation can be a long pressing operation and the long pressing time is longer than a preset time length.

[0091] Based on this, when the execution subject of the present application detects a triggering operation for the monitoring picture, the corresponding triggering position of the triggering operation in the monitoring picture can be determined.

[0092] Step 103, determining a target area in the preset area according to the trigger position.

[0093] The target area refers to the actual area corresponding to the screen area focused by the user in the monitoring screen in the preset area. Further, the screen area focused by the user in the monitoring screen is determined according to the trigger position of the user on the monitoring screen.

[0094] In an embodiment, after determining the trigger position of the user in the monitoring screen, the execution subject of the embodiment can take the trigger position as the focus point of the user watching the monitoring screen, so as to determine the target area in the preset area that the user wants to focus on according to the trigger position.

[0095] As an optional implementation, the target screen area in the monitoring screen can be determined according to the trigger position. The target screen area is the screen area focused by the user in the monitoring screen.

[0096] As an exemplary embodiment, when determining the target screen area, the coordinate information of the trigger position in the monitoring screen can be obtained. Then, the target screen area in the monitoring screen can be determined with the coordinate point corresponding to the coordinate information as the center and a preset pixel as the radius. The preset pixel is a pixel value set in advance, for example, 50 pixels.

[0097] As another exemplary embodiment, a preset shape area can be set in advance. Based on this, when determining the target screen area, the coordinate information of the trigger position in the monitoring screen can be obtained. Then, the coordinate point corresponding to the coordinate information can be taken as the midpoint of the preset shape area, and the screen area corresponding to the preset shape is determined as the target screen area.

[0098] Then, the area monitored by the target screen area in the preset area can be determined, and the area monitored by the target screen area is determined as the target area. The screen area of the monitoring screen and the preset area are in a mapping relationship, the target screen area is a partial area in the monitoring screen, and the target area is a partial area in the actual area. The actual area corresponding to the target screen area is the target area.

[0099] Step 104, collecting the current brightness of the target area.

[0100] Step 105, adjusting the brightness of the target area based on the current brightness.

[0101] The following is a unified description of steps 104 and 105:

[0102] The current brightness refers to the actual brightness of the target region at present, which can be the average brightness in the target region, or the maximum brightness or the minimum brightness of the target region, and the embodiments of the present application do not limit this.

[0103] In an embodiment, after the subject of the embodiments of the present application determines the target region according to the trigger position of the user in the monitoring picture, the current brightness of the target region can be acquired, so that the brightness of the target region is adjusted based on the current brightness, so that the brightness of the target region reaches the target brightness. When the brightness of the target region reaches the target brightness, the target picture region corresponding to the target region in the monitoring picture is clearer, so that the user can more clearly view the target region through the target picture region.

[0104] As an optional implementation, when the current brightness of the target region is collected, the initial brightness of a plurality of sub-regions in the current target region can be collected, and the collected plurality of initial brightnesses are weighted and averaged to obtain the current brightness of the target region.

[0105] As another optional implementation, when the current brightness of the target region is collected, a plurality of brightness values currently collected by the target region can be determined, and a target brightness value is selected from the plurality of brightness values as the current brightness of the target region. Among them, the brightness value with the highest frequency of occurrence in the plurality of brightness values can be determined as the current brightness of the target region.

[0106] As to how to adjust the brightness of the target region based on the current brightness, it can be explained by the flow shown in FIG. 2, which will not be described in detail here.

[0107] The technical scheme provided by the embodiments of the present application acquires the monitoring picture of the preset region by the monitoring device, and displays the monitoring picture. In the case that a trigger operation for the monitoring picture is received, the trigger position corresponding to the trigger operation in the monitoring picture is determined, the target region in the preset region is determined according to the trigger position, the current brightness of the target region is collected, and the brightness of the target region is adjusted based on the current brightness. This technical scheme determines the target region concerned by the user according to the trigger operation of the user for the monitoring picture, and adjusts the brightness of the target region according to the current brightness of the target region after collecting the current brightness of the target region, so that the monitoring region concerned by the user can be adjusted individually, the brightness of the monitoring region concerned by the user is adjusted with pertinence, the brightness adjustment effect of the monitoring picture is improved, and the user experience is improved.

[0108] Referring to FIG. 2, an embodiment flow chart of another method for adjusting the brightness of a monitoring picture according to an embodiment of the present application is shown. The flow chart shown in FIG. 2 describes how to adjust the brightness of the target region based on the current brightness of the target region, based on the flow chart shown in FIG. 1. As shown in FIG. 2, the flow chart can include the following steps:

[0109] Step 201: Determine whether the current brightness is within a preset brightness interval. If not, proceed to step 202; if yes, end the flow chart.

[0110] Step 202: Obtain the current light compensation brightness of the light compensation module.

[0111] The following describes steps 201 and 202:

[0112] The above-mentioned brightness interval refers to a preset brightness convergence interval for adjusting the brightness of the target region. Further, the above-mentioned brightness interval can be determined based on a preset target brightness and a convergence range. For example, the above-mentioned target brightness is 20, and the above-mentioned convergence range is 10, so the brightness interval is (10, 30).

[0113] The above-mentioned light compensation module refers to a device for compensating light for the preset region, such as a light compensation lamp. The type and installation position of the light compensation module are not limited in the embodiments of the present application.

[0114] The above-mentioned current light compensation brightness refers to the current brightness of the light compensation module.

[0115] In an embodiment, after the current brightness of the target region is obtained, it can be determined whether the current brightness is within the above-mentioned brightness interval.

[0116] Optionally, if the current brightness is within the above-mentioned brightness interval, it indicates that the current brightness of the target region at this time can make the definition of the corresponding target picture region in the monitoring picture meet the preset requirement, and therefore, the brightness of the target region can not be adjusted.

[0117] On the contrary, if the current brightness is outside the above-mentioned brightness interval, it indicates that the current brightness of the target region at this time is insufficient to make the definition of the corresponding target picture region in the monitoring picture meet the preset requirement, and therefore, the brightness of the target region needs to be adjusted.

[0118] Further, when adjusting the brightness of the target region, the brightness of the target region can be adjusted by adjusting the brightness of the light compensation module, and therefore, when it is determined that the current brightness is outside the brightness interval, the current light compensation brightness of the light compensation module can be obtained.

[0119] As an optional implementation, the execution subject of the embodiments of the present application can be connected to the above-mentioned light compensation module, and based on this, the execution subject of the embodiments of the present application can directly obtain the current brightness of the light compensation module.

[0120] Step 203, determining the first target light compensation brightness of the light compensation module according to the current brightness, the current light compensation brightness, and the preset target brightness.

[0121] Step 204, adjusting the brightness of the light compensation module from the current light compensation brightness to the first target light compensation brightness to adjust the brightness of the target region.

[0122] The following describes steps 203 and 204:

[0123] The target brightness refers to a preset brightness value. When the brightness value of the target region is the target brightness, the definition of the target picture region corresponding to the target region in the monitoring picture is best, that is, the user can clearly view the target region.

[0124] In the embodiment of the application, when the brightness of the target region is adjusted, the brightness of the target region can be adjusted by adjusting the brightness of the light compensation module. Based on this, the execution subject of the embodiment of the application can determine the target light compensation brightness (hereinafter referred to as the first target light compensation brightness) of the light compensation module according to the current brightness, the current light compensation brightness, and the preset target brightness. Then, the brightness of the light compensation module can be adjusted from the current light compensation brightness to the first target light compensation brightness to adjust the brightness of the target region to the target brightness.

[0125] As an optional implementation, the first target light compensation brightness of the light compensation module can be determined by the flow shown in FIG. 3.

[0126] Referring to FIG. 3, FIG. 3 is an embodiment flowchart of another method for adjusting the brightness of a monitoring picture provided by the application. The flow shown in FIG. 3 describes how to determine the first target light compensation brightness of the light compensation module based on the flow shown in FIG. 2. As shown in FIG. 3, the flow can include the following steps:

[0127] Step 301, determining whether the current light compensation brightness is less than a first preset value. If yes, step 302 is performed; if no, step 303 is performed.

[0128] Step 302, determining the first target light compensation brightness of the light compensation module according to the current brightness and the target brightness.

[0129] The following describes steps 301 and 302:

[0130] The first preset value is a preset brightness value. Further, the first preset value can be a small brightness value, for example, 1.

[0131] In the embodiment of the present application, when the first target light supplementing brightness of the light supplementing module is determined, the current light supplementing brightness of the light supplementing module can be compared with the first preset value first. Further, it can be determined whether the current light supplementing brightness is less than the first preset value.

[0132] Optionally, if the current light supplementing brightness is less than the first preset value, it indicates that the brightness value corresponding to the light supplementing module at this time is low, which can indicate that the current brightness value of the target region is high, and therefore the first target light supplementing brightness of the light supplementing module can be further determined according to the current brightness and the target brightness of the target region.

[0133] As an exemplary manner, when the first target light supplementing brightness of the light supplementing module is determined according to the current brightness and the target brightness of the target region, it can be determined whether the current brightness of the target region is less than the target brightness.

[0134] As an embodiment, when it is determined that the current brightness is less than the target brightness, it indicates that the brightness of the target region needs to be adjusted to be brighter, that is, the current light supplementing brightness of the light supplementing module needs to be increased, and therefore the minimum brightness value of the light supplementing module can be added to the first preset value to obtain the first target light supplementing brightness of the light supplementing module.

[0135] As another embodiment, when it is determined that the current brightness is greater than the target brightness, it indicates that the brightness of the target region needs to be adjusted to be lower, that is, the light supplementing brightness of the light supplementing module needs to be reduced, and therefore the minimum brightness value of the light supplementing module can be determined as the first target light supplementing brightness of the light supplementing module.

[0136] Optionally, if it is determined that the current light supplementing brightness is greater than or equal to the first preset value, it indicates that the current brightness of the target region at this time is low, and therefore the following step 303 can be further performed.

[0137] Step 303: determining whether the current brightness is equal to a second preset value, if yes, performing step 304; if no, performing step 305.

[0138] Step 304: determining the maximum brightness value of the light supplementing module as the first target light supplementing brightness of the light supplementing module.

[0139] Step 305: determining the ratio of the target brightness to the current brightness, and multiplying the current light supplementing brightness by the ratio to obtain the first target light supplementing brightness of the light supplementing module.

[0140] The following uniformly describes steps 303 to 305:

[0141] The second preset value can be a brightness value less than the first preset value, for example, 0.

[0142] In the embodiments of the present application, when it is determined that the current light supplement brightness of the light supplement module is greater than or equal to the first preset value, it indicates that the current brightness of the target region is low, and thus it can be determined whether the current brightness is equal to the second preset value.

[0143] Optionally, if the current brightness is equal to the second preset value, it indicates that the current brightness of the target region is extremely low, and thus, in order to improve the brightness of the target region, the maximum brightness value of the light supplement module can be determined as the first target light supplement brightness of the light supplement module.

[0144] On the contrary, if the current brightness is not equal to the second preset value, it indicates that the current brightness of the target region is low but not the lowest, and thus the first target light supplement brightness of the light supplement module can be further determined according to the current brightness and the target brightness.

[0145] As an exemplary embodiment, the ratio of the target brightness to the current brightness can be determined, and the first target light supplement brightness of the light supplement module can be obtained by multiplying the current light supplement brightness by the ratio.

[0146] Thus far, the description of the flow shown in FIG. 3 is completed.

[0147] In addition, in order to limit the first target light supplement brightness of the light supplement module, the subject performing the embodiments of the present application can compare the first target light supplement brightness with the maximum brightness value and the minimum brightness value of the light supplement module respectively after determining the first target light supplement brightness of the light supplement module.

[0148] Optionally, in the case that the first target light supplement brightness is greater than the maximum brightness value, the brightness value of the light supplement module cannot be adjusted to the first target light supplement brightness at this time, and thus the first target light supplement brightness can be updated to the maximum brightness value.

[0149] On the contrary, in the case that the first target light supplement brightness is less than the minimum brightness value, the brightness value of the light supplement module cannot be adjusted to the first target light supplement brightness at this time, and thus the first target light supplement brightness can be updated to the minimum brightness value.

[0150] In an embodiment, when the brightness of the light supplement module is adjusted from the current light supplement brightness to the first target light supplement brightness, in order to prevent the step of adjustment being too large and thus causing flickering, the step value of brightness adjustment of the light supplement module can be first determined based on the current light supplement brightness.

[0151] As an exemplary embodiment, when the step value of brightness adjustment of the light supplement module is determined, in order to reduce the number of adjustments, the maximum value of the step value can be first limited. Specifically, the current light supplement brightness can be multiplied by a preset ratio to obtain a first step value. The preset ratio is a smaller percentage of the current light supplement brightness, for example, 0.15.

[0152] Afterwards, the first step length value can be compared with a preset second step length value (for example, 5). Alternatively, if the first step length value is greater than or equal to the second step length value, the first step length value can be determined as the step length value for adjusting the brightness of the light compensation module. Conversely, if the first step length value is less than the second step length value, the second step length value can be determined as the step length value for adjusting the brightness of the light compensation module.

[0153] After the step length value is determined, it can be determined whether the first target light compensation brightness is greater than or equal to the sum of the current light compensation brightness and the step length value. Alternatively, if it is determined that the first target light compensation brightness is greater than or equal to the sum of the current light compensation brightness and the step length value, it indicates that the light compensation brightness of the light compensation module after adjustment according to the step length value will not exceed the first target light compensation brightness. Therefore, the light compensation brightness of the light compensation module can be sequentially increased according to the step length value until the first target light compensation brightness is reached.

[0154] Further, if the first target light compensation brightness is greater than the current light compensation brightness, and the first target light compensation brightness is less than the sum of the current light compensation brightness and the step length value, the difference between the first target light compensation brightness and the current light compensation brightness can be determined, and the light compensation brightness of the light compensation module can be increased according to the difference.

[0155] Alternatively, if it is determined that the first target light compensation brightness is less than the sum of the current light compensation brightness and the step length value, it is further determined whether the first target light compensation brightness is less than or equal to the difference between the current light compensation brightness and the step length value.

[0156] Alternatively, in the case where it is determined that the first target light compensation brightness is less than or equal to the difference between the current light compensation brightness and the step length value, it indicates that the light compensation brightness of the light compensation module will not be lower than the first target light compensation brightness after being reduced according to the step length value. Therefore, the light compensation brightness of the light compensation module can be sequentially reduced according to the step length value until the first target light compensation brightness is reached.

[0157] Further, if the first target light compensation brightness is greater than the difference between the current light compensation brightness and the step length value, and the first target light compensation brightness is less than the current light compensation brightness, the light compensation brightness of the light compensation module can be reduced according to the difference so that the light compensation module reaches the first target light compensation brightness.

[0158] In addition, after the light compensation brightness of the light compensation module is adjusted to the first target light compensation brightness, if the first target light compensation brightness has reached the maximum light compensation brightness of the light compensation module, but the target region has not reached the target brightness, at this time, the gain of the target region can be further adjusted according to the method of adjusting the light compensation brightness of the light compensation module, so as to increase the clarity of the target picture region corresponding to the target region.

[0159] In addition, in order to ensure that the target region corresponds to the picture effect of the target picture region, the execution subject of the embodiment of the present application can determine a light measurement frame centered on the trigger position and display the light measurement frame in the monitoring picture. Based on this, the light measurement frame can be subjected to AE (Automatic Exposure, automatic exposure control device) locking before the target region is subjected to brightness adjustment, and then the light compensation brightness of the light compensation module is adjusted in combination with the AE data corresponding to the AE locking in the process of adjusting the brightness of the target region.

[0160] In addition, if the trigger operation for the monitoring picture is not detected after a preset time period (for example, 30 s), the brightness of the light compensation module is restored to the previous current light compensation brightness, and the AE is unlocked.

[0161] The technical scheme provided by the embodiment of the present application determines whether the current brightness is located in the preset brightness interval. If not, the current light compensation brightness of the light compensation module is obtained, the first target light compensation brightness of the light compensation module is determined according to the current brightness, the current light compensation brightness, and the preset target brightness, and the brightness of the light compensation module is adjusted from the current light compensation brightness to the first target light compensation brightness, so as to adjust the brightness of the target region. If yes, the process is ended. This technical scheme adjusts the brightness of the target region by using the light compensation module, and further determines the target light compensation brightness of the light compensation module according to the current brightness and the target brightness of the target region and the current light compensation brightness of the light compensation module. The target light compensation brightness of the light compensation module determined by referring to multiple brightness values is more accurate, and the brightness of the target region is adjusted more accurately.

[0162] Referring to FIG. 4, an embodiment flowchart of another monitoring picture brightness adjustment method provided by the embodiment of the present application is shown. The flowchart shown in FIG. 4 is based on the flowcharts shown in FIG. 2 or FIG. 3, and describes further adjusting the brightness of the target region by human operation. As shown in FIG. 4, the flowchart can include the following steps:

[0163] Step 401: Obtain a monitoring picture of a preset region of a monitoring device, and display the monitoring picture.

[0164] Step 402: In the case where a trigger operation for the monitoring picture is received, determine the trigger position corresponding to the trigger operation in the monitoring picture.

[0165] For detailed descriptions of steps 401 and 402, refer to the descriptions in steps 101 and 103, which will not be described here.

[0166] Step 403: Obtain the current light compensation brightness of the light compensation module.

[0167] Step 404: outputting a light supplement adjustment control at the trigger position, the light supplement adjustment control being used to display the current light supplement brightness and adjust the light supplement brightness of the light supplement module.

[0168] The steps 403 and 404 are described as follows:

[0169] The light supplement adjustment control is a control output at the trigger position, which can be used to display the current light supplement brightness of the light supplement module and adjust the light supplement brightness of the light supplement module by dragging the progress bar and the like. Further, the light supplement adjustment control can include a progress bar, which can correspond to the light supplement brightness range of the light supplement module, that is, the maximum brightness value (for example, 100) and the minimum brightness value (for example, 0) of the light supplement module at both ends of the progress bar. Based on this, the user can adjust the progress bar to adjust the light supplement brightness of the light supplement module.

[0170] In the embodiments of the present application, when the trigger operation of the user on the monitoring picture is detected and the trigger position corresponding to the trigger operation is determined, the current light supplement brightness of the light supplement module can be collected, and a light supplement adjustment control can be output at the trigger position, and the current light supplement brightness can be displayed in the light supplement adjustment control.

[0171] Step 405: in the case that the dragging operation on the light supplement adjustment control is received, the second target light supplement brightness corresponding to the light supplement adjustment control after being dragged is acquired.

[0172] Step 406: adjusting the light supplement brightness of the light supplement module from the current light supplement brightness to the second target light supplement brightness.

[0173] The steps 405 and 406 are described as follows:

[0174] In the embodiments of the present application, when the light supplement adjustment control is output on the monitoring picture, when the user needs to adjust the brightness of the target region by himself, the light supplement brightness of the light supplement module can be adjusted by dragging the light supplement adjustment control. Based on this, the execution subject of the embodiments of the present application can acquire the second target light supplement brightness corresponding to the light supplement adjustment control after being dragged in the case that the dragging operation on the light supplement adjustment control is received.

[0175] Then, the light supplement brightness of the light supplement module can be adjusted from the current light supplement brightness to the second target light supplement brightness.

[0176] Further, when the light supplement brightness of the light supplement module is updated, the light supplement module can timely send the updated light supplement brightness to the execution subject of the embodiments of the present application, and the execution subject of the embodiments of the present application can update the current light supplement brightness of the light supplement module displayed in the light supplement adjustment control after receiving the light supplement brightness.

[0177] In addition, if the triggering operation for the monitoring picture is not detected after a preset time period (for example, 30 s), the brightness of the light compensation module is restored to the previous current light compensation brightness.

[0178] It should be noted that the flow shown in FIG. 4 can also occur in the process shown in FIG. 2, that is, in the process of automatically adjusting the brightness of the target region, if the user's drag operation on the light compensation adjustment control is detected, the light compensation brightness of the light compensation module is adjusted according to the determined second target light compensation brightness.

[0179] The technical scheme provided by the embodiments of the present application comprises the following steps: acquiring a monitoring picture of a preset region by a monitoring device, and displaying the monitoring picture; in the case that a triggering operation for the monitoring picture is received, determining a triggering position corresponding to the triggering operation in the monitoring picture, acquiring a current light compensation brightness of a light compensation module, outputting a light compensation adjustment control at the triggering position, the light compensation adjustment control being used to display the current light compensation brightness and adjust the light compensation brightness of the light compensation module; in the case that a drag operation for the light compensation adjustment control is received, acquiring a second target light compensation brightness corresponding to the light compensation adjustment control after being dragged, and adjusting the light compensation brightness of the light compensation module from the current light compensation brightness to the second target light compensation brightness. This technical scheme outputs the light compensation adjustment control, so that the user can adjust the brightness of the target region according to the light compensation adjustment control, realizes the flexibility of adjusting the brightness of the target region, and improves the user experience.
