Before the embodiments of the present application are specifically described, application scenarios of the present application are described.

In order to solve the problem, embodiments of the present application provide a projection control method, apparatus, electronic device, and computer readable storage medium, which can automatically adjust the brightness of the environment according to the content type played by the projector, so as to improve the continuity of the viewing process and the viewing experience of the user.

It should be noted that, the projection control method provided in the embodiment of the present application is mainly applied to a controller of a projection system, that is, each step in the projection control method is implemented by the controller.

Referring to fig. 1, the projection system includes: projector 101, intelligent curtain 102, lighting device 103 and controller 104, controller 104 is connected with projector 101, lighting device 103 and intelligent curtain 102 communication.

The intelligent curtain 102 is usually installed at a window of a room, and can automatically adjust the opening and closing degree according to an instruction sent by the controller 104, if the current time is daytime or the brightness of light outside the window is higher, the change of the opening and closing degree of the intelligent curtain 102 can change the brightness of the environment in the room on the premise that other factors influencing the brightness of the environment in the room are unchanged. For example, the brightness of the light outside the window is high, and increasing the opening and closing degree of the smart curtain 102 increases the ambient light brightness in the room.

In this embodiment of the present application, increasing the opening and closing degree of the intelligent curtain 102 specifically refers to reducing the shielding area of the intelligent curtain 102 to the window, and decreasing the opening and closing degree of the intelligent curtain 102 specifically refers to increasing the shielding area of the intelligent curtain 102 to the window.

The lighting device 103 is typically installed in a room and can automatically adjust the brightness according to instructions sent by the controller 104. The brightness of the light fixture 103 can change the ambient light level in the room without changing other factors that affect the ambient light level in the room. For example, increasing the brightness of the light 103 may increase the ambient light level in the room. The number of the light devices 103 may be plural, and the brightness of the environment in the room may be changed by adjusting the brightness of a part of the light devices 103, or the brightness of all the light devices 103 may be adjusted, which is not limited in this application.

The lighting device 103 in this embodiment of the present application may be integrated or partially integrated on the projector 101, as shown in fig. 2, that is, the projector 101 is also a ceiling lamp, the top of the ceiling lamp is fixed on the roof of the house, the side is the projector 101, and the bottom is the lighting device 103.

Referring to fig. 3, the present application provides a projection control method, which includes:

S301: the method comprises the steps of detecting a current working mode of the projector, wherein the current working mode of the projector is used for indicating the type of the current playing content of the projector.

Specifically, the projector may preset a plurality of operation modes for different types of play contents. The type of the playing content is mainly used for indicating the category to which the playing content belongs, for example, the type of the playing content may include a movie, a game, music, work, etc., a working mode corresponding to the movie may be a movie viewing mode, a working mode corresponding to the game may be a game mode, a working mode corresponding to the music may be a music mode, and a mode corresponding to the work may be an office mode. Of course, the operation mode may also include an atmosphere mode, a singing mode, etc., which are only exemplary, and the present application is not limited thereto.

S302: and determining a current target brightness interval corresponding to the current working mode of the projector according to the preset corresponding relation between the working mode of the projector and the brightness interval.

Alternatively, the correspondence relationship between the operation mode of the projector and the brightness interval may be preset. For example, referring to fig. 4, a first mapping table may be preset, where the first mapping table includes a plurality of operation modes and a plurality of brightnesses of the projector, and the first mapping table is used to indicate a correspondence between the operation modes and brightness intervals of the projector, and each brightness interval may overlap, which is not limited.

On this basis, step S302 may specifically be: and determining a current target brightness interval corresponding to the current working mode of the projector according to the first mapping table. Of course, the correspondence between the operation mode of the projector and the brightness interval may be preset by other means, and the present application is not limited thereto.

In addition, it should be specifically noted that, in the embodiment of the present application, the luminance interval may be a value, and then, step S302 may specifically be: and determining the current brightness value corresponding to the current working mode of the projector according to the preset corresponding relation between the working mode of the projector and the brightness value.

S303: and adjusting the opening and closing degree of the intelligent curtain and/or the brightness of the lighting equipment according to the current ambient light brightness and the current target brightness interval until the adjusted ambient light brightness is matched with the current target brightness interval.

In this embodiment of the present application, the matching between the adjusted ambient light brightness and the current target brightness interval may specifically refer to: the adjusted ambient light brightness is within the current target brightness interval, i.e., the adjusted ambient light brightness is greater than or equal to the minimum value of the current target brightness interval and less than or equal to the maximum value of the current target brightness interval.

Optionally, the opening and closing degree of the intelligent curtain and/or the brightness of the lighting device may be adjusted according to the current ambient light brightness and the current target brightness interval, which specifically includes: detecting the current ambient light brightness; and if the current ambient light brightness is outside the current target brightness interval, adjusting the opening and closing degree of the intelligent curtain and/or the brightness of the light equipment.

According to the projection control method provided by the embodiment of the application, the current working mode of the projector is detected firstly, then the current target brightness interval corresponding to the current working mode of the projector is determined according to the corresponding relation between the preset working mode of the projector and the brightness interval, finally the opening and closing degree of the intelligent curtain and/or the brightness of the lighting equipment are adjusted according to the current environment brightness and the current target brightness interval until the adjusted environment brightness is matched with the current target brightness interval, so that the environment brightness is automatically adjusted according to the content type played by the projector, and the continuity and the watching experience of a user in the watching process are improved.

Referring to fig. 5, in an alternative embodiment, step S301, i.e. the specific step of detecting the current operation mode of the projector, may be step S501a or step S501b. Step S501a shows a method of determining a current operation mode according to a target operation instruction received by the projector, and step S502 shows a method of determining a current operation mode according to a current play frame of the projector.

The step S501a may specifically be: and acquiring a target operation instruction received by the projector, wherein the target operation instruction is the latest operation instruction for instructing the projector to start a target working mode or switch to the target working mode, and taking the target working mode as the current working mode of the projector.

Specifically, the projector can determine the operation mode, the play parameter, and the like by receiving the operation instruction. For example, the operation mode may include an on-viewing mode, the play parameter may include a play volume, and the operation instruction received by the projector may instruct to turn on the viewing mode and play at 50% of the volume. Of course, the description is merely illustrative and the present application is not limited thereto.

It should be noted that, the projector receives a plurality of operation instructions at a plurality of time points, and the latest operation instruction is the operation instruction corresponding to the time point closest to the current time point, that is, the operation instruction corresponding to the time point with the smallest absolute value of the difference value from the current time point, among all the time points for receiving the operation instructions.

Step S501a is described here by way of example. For example, three operation instructions are received by the projector, namely a first operation instruction received by a first time point, a second operation instruction received by a second time point and a third operation instruction received by a third time point, wherein the absolute value of the difference between the first time point and the current time point is minimum, the absolute value of the difference between the third time point and the current time point is maximum, the first operation instruction indicates that the playing volume is adjusted to 50%, the second operation instruction indicates that the working mode is switched to the film watching mode, and the third operation instruction indicates that the working mode is switched to the music mode. On the basis, although the first operation instruction is closest to the current time point, the first operation instruction does not instruct the projector to start a certain working mode or switch to a certain working mode, that is, the first operation instruction is not a target operation instruction, the second operation instruction instructs the projector to switch the working mode to the viewing mode, and the receiving time point is closer to the current time point than the receiving time point of the third operation instruction, that is, the second operation instruction is a target operation instruction, and step S501a may specifically be: and acquiring a second operation instruction received by the projector, and taking the film watching mode as the current working mode of the projector.

In addition, the step of determining the current operation mode of the projector through the current play image of the projector, that is, step S501b may specifically include: the method comprises the steps of obtaining a current playing picture of a projector, judging the type of playing content corresponding to the current playing picture, and taking a working mode corresponding to the type of the playing content corresponding to the current playing picture as the current working mode of the projector.

In an optional implementation manner, before determining the type of the play content corresponding to the current play frame, the method may further include: and acquiring the play pictures in the play contents of the preset number and different types, and training an initial model by taking the play pictures of the preset number and the corresponding types as training data to obtain a classification model.

On this basis, the judging of the type of the play content corresponding to the current play picture may include: and inputting the current playing picture into a classification model, and taking the output result of the classification model aiming at the current playing picture as the type of the playing content corresponding to the current playing picture.

In another optional implementation manner, before determining the type of the play content corresponding to the current play frame, the method may further include: a database is pre-established, and the database can comprise lyrics, video lines, game lines, working data and the like.

On this basis, the judging of the type of the play content corresponding to the current play picture may include: extracting text information in a current playing picture; searching data corresponding to the text information in the database, if the corresponding data is lyrics, determining that the type of the playing content corresponding to the current playing picture is music, and taking a music mode as the current working mode of the projector; if the corresponding data is a movie and television line, the type of the playing content corresponding to the current playing picture can be determined to be a movie, and the film watching mode can be used as the current working mode of the projector; if the corresponding data is a game word, determining that the type of the playing content corresponding to the current playing picture is a game, and taking the game mode as the current working mode of the projector; if the corresponding data is working data, the type of the playing content corresponding to the current playing picture can be determined to be working, and the office mode can be used as the current working mode of the projector.

Referring to fig. 6, in an alternative embodiment, before adjusting the opening and closing degree of the intelligent curtain and/or the brightness of the lighting device according to the current ambient light brightness and the current target brightness interval in step S303, the method further includes:

S601: under different environmental parameters, a first conversion relation between the unit change amount of the ambient light brightness and the unit change amount of the opening and closing degree of the intelligent curtain and a second conversion relation between the unit change amount of the ambient light brightness and the unit change amount of the brightness of the light equipment are established, and the environmental parameters comprise at least one of time and weather.

In general, the relationship between the unit change amount of the ambient light brightness and the unit change amount of the opening and closing degree of the intelligent curtain and the unit change amount of the brightness of the lighting equipment can be influenced at different time points and in different weather in one day. According to the embodiment of the application, the conversion relation among the unit variable quantities is established under different environment parameters, so that the intelligent curtain and/or the lighting equipment can be regulated more accurately.

The unit change amount of the opening and closing degree means a change amount of one opening and closing degree unit, for example, if the unit of the opening and closing degree is cm, the unit change amount of the opening and closing degree means 1 cm; the luminance unit variation is a variation of one luminance unit.

For example, if the environment parameters include T ₁ ,T ₂ ,T ₃ ,T ₄ The unit brightness change of the ambient light is DeltaLux, the unit change of the opening and closing degree of the intelligent curtain is DeltaL, and the unit brightness change of the lighting equipment is DeltaX, then T can be the same as the unit brightness change of the intelligent curtain ₁ Then, a first conversion relation delta Lux-S1×DeltaL is established, wherein the first conversion relation represents that the opening and closing degree of the intelligent curtain changes by S1×DeltaL, and the first conversion relation can cause the change of the ambient light brightness by one unit, the second conversion relation delta Lux-C1×DeltaX represents that the brightness of the light equipment changes by C1×DeltaX, and the second conversion relation represents that the ambient light brightness changes by one unit; at T ₂ Then, a first conversion relation delta Lux-S2×DeltaL is established, wherein the first conversion relation represents that the opening and closing degree of the intelligent curtain changes by S2×DeltaL, and the first conversion relation can cause the change of the ambient light brightness by one unit, the second conversion relation delta Lux-C2×DeltaX represents that the brightness of the light equipment changes by C2×DeltaX, and the second conversion relation represents that the ambient light brightness changes by one unit; at T ₃ Then, a first conversion relation delta Lux-S3×DeltaL is established, wherein the first conversion relation represents that the opening and closing degree of the intelligent curtain changes by S3×DeltaL, and the first conversion relation can cause the change of the ambient light brightness by one unit, the second conversion relation delta Lux-C3×DeltaX represents that the brightness of the light equipment changes by one unit, and the second conversion relation represents that the brightness of the light equipment changes by C3×DeltaX; at T ₄ Then, a first conversion relation DeltaLux-S4×DeltaL is established, wherein the first conversion relation represents that the opening and closing degree of the intelligent curtain changes by S4×DeltaL, and the environmental light brightness changes by one unit, and a second conversion relation DeltaLux-C4×DeltaX represents that the brightness of the light equipment changes by one unit. Wherein, S1, S2, S3, S4, C1, C2, C3 and C4 are all larger than 0.

Therefore, under different environmental parameters, a first conversion relation between the unit change amount of the ambient light brightness and the unit change amount of the opening and closing degree of the intelligent curtain and a second conversion relation between the unit change amount of the ambient light brightness and the unit change amount of the brightness of the light equipment are established, so that different adjustment strategies are adopted under different environmental parameters, and the accuracy and precision of projection control are improved.

Of course, in the embodiment of the present application, the first conversion relationship between the unit change amount of the ambient light brightness and the unit change amount of the openable window curtain, and the second conversion relationship between the unit change amount of the ambient light brightness and the unit change amount of the brightness of the lighting device may be directly established without considering the environmental parameters.

Referring to fig. 7, in an alternative embodiment, in step S303, adjusting the opening and closing degree of the intelligent curtain and/or the brightness of the lighting device according to the current ambient light brightness and the current target brightness interval specifically includes:

s701: and calculating the difference value between the current ambient light brightness and any value in the current target brightness interval.

S702: and acquiring the current environmental parameter, and calculating the opening and closing degree to-be-adjusted quantity of the intelligent curtain according to the first conversion relation and the difference value corresponding to the current environmental parameter.

S703: judging whether the intelligent curtain is in an invalid control mode according to a first conversion relation corresponding to the current environmental parameters or the opening and closing degree to-be-adjusted quantity of the intelligent curtain.

S704a: if yes, the brightness of the lighting equipment is adjusted according to the current environmental parameters and the difference value.

S704b: if not, the opening and closing degree of the intelligent curtain is adjusted according to the opening and closing degree to be adjusted of the intelligent curtain, or the brightness of the lighting equipment and the opening and closing degree of the intelligent curtain are adjusted according to the current environment parameters and the difference value.

Taking the example in step S601, if the current ambient light level is Lux, the current target brightness interval is [ a, b ]]Any value m is taken in the current target brightness interval, and the current environment parameter is T ₁ The first conversion relation corresponding to the current environmental parameter is DeltaLux-S1×DeltaL, the first conversion relation represents that when the opening and closing degree of the intelligent curtain changes S1×DeltaL, the change of the environmental light brightness is caused by one unit, and as can be known from Lux and m, the total change of the environmental light brightness under the current environmental parameter is Lux-m units, so that the opening and closing degree of the intelligent curtain can be further determinedFor example, if the first conversion relationship is Δlux=s1×Δl, the amount to be adjusted of the opening/closing degree of the smart curtain is (Lux-m) ×s1×Δl.

The amount of to-be-adjusted opening and closing degree of the intelligent curtain can be positive or negative, if Lux-m is larger than 0, the amount of to-be-adjusted opening and closing degree of the intelligent curtain is positive, which means that the shielding area of the intelligent curtain to the window needs to be increased, the intelligent curtain can be adjusted towards the direction of increasing the shielding area of the window, and if Lux-m is smaller than 0, the amount of to-be-adjusted opening and closing degree of the intelligent curtain is negative, which means that the shielding area of the intelligent curtain to the window needs to be reduced, and the intelligent curtain can be adjusted towards the direction of reducing the shielding area of the window.

If the intelligent curtain is in the invalid control mode, the fact that the current ambient light brightness cannot be adjusted to the current target brightness interval by adjusting the intelligent curtain is indicated, and when the intelligent curtain is in the invalid control mode, the brightness of the light equipment is adjusted, so that the adjusting process is simplified, and the adjusting efficiency is improved.

If the intelligent curtain is not in an invalid control mode, the intelligent curtain is only adjusted to adjust the current ambient light brightness to a current target brightness interval, and on the basis, the embodiment of the application can not only adjust the opening and closing degree of the intelligent curtain, but also can be comprehensively adjusted by combining the brightness of the lighting equipment and the opening and closing degree of the intelligent curtain.

Optionally, step S703, that is, determining whether the intelligent curtain is in the invalid control mode according to the first conversion relationship corresponding to the current environmental parameter, may specifically include: if the first conversion relation corresponding to the current environment parameter indicates that the unit change amount of the ambient light brightness is smaller than or equal to a first preset threshold value, judging that the intelligent curtain is in an invalid control mode, otherwise, judging that the intelligent curtain is not in the invalid control mode.

The first preset threshold may be set according to actual requirements, which is not limited in this application.

For example, when the brightness of the light outside the window is low, for example, the time point in the environmental parameter is night, the opening and closing degree of the intelligent curtain is adjusted anyway, the unit change amount of the environmental light is 0 or very small, and then the intelligent curtain can be judged to be in the ineffective control mode.

Optionally, step S703, namely, determining whether the intelligent curtain is in the invalid control mode according to the to-be-adjusted opening/closing degree of the intelligent curtain may further specifically include: acquiring the opening and closing degree adjustable quantity of the intelligent curtain; if the opening and closing degree adjustable quantity is smaller than the opening and closing degree to-be-adjusted quantity, judging that the intelligent curtain is in an invalid control mode, otherwise, judging that the intelligent curtain is not in the invalid control mode.

The adjustable opening and closing degree of the intelligent curtain has a determined value range, the minimum value is 0, the maximum opening and closing degree of the intelligent curtain can be only equal to the maximum opening and closing degree of the intelligent curtain, and the adjustable opening and closing degree of the intelligent curtain can specifically comprise an adjustment amount for adjusting the current opening and closing degree of the intelligent curtain to 0 and an adjustment amount for adjusting the current opening and closing degree of the intelligent curtain to the maximum opening and closing degree. If the opening and closing degree adjustable quantity is smaller than the opening and closing degree to-be-adjusted quantity, the current ambient light brightness cannot be adjusted to the current target brightness interval no matter how the opening and closing degree of the intelligent curtain is adjusted, for example, the curtain is fully opened or fully closed, the current ambient light brightness cannot be adjusted to the current target brightness interval, and the intelligent curtain can be judged to be in an invalid control mode.

Referring to fig. 8, in an alternative embodiment, the adjusting the brightness of the light device in step S704a specifically includes:

s801: and calculating the brightness to-be-adjusted quantity of the light equipment according to the second conversion relation and the difference value corresponding to the current environment parameters.

S802: and adjusting the brightness of the light equipment according to the brightness to-be-adjusted quantity of the light equipment.

Still using the example in step S601, if the current ambient light level is Lux, the current target brightness interval is [ a, b ] ]Any value m is taken in the current target brightness interval, and the current environment parameter is T ₁ The second conversion relation corresponding to the current environmental parameter is Δlux=c1×Δl, and the difference value is Lux-m, and the luminance to be adjusted of the lighting device is:

optionally, the luminance to-be-adjusted amount of the light device may be a positive number or a negative number, if Lux-m is greater than 0, the luminance to-be-adjusted amount of the light device is a positive number, which indicates that the luminance of the light device needs to be reduced, and if Lux-m is less than 0, the luminance to-be-adjusted amount of the light device is a negative number, which indicates that the luminance of the light device needs to be increased.

Referring to fig. 9, in an alternative embodiment, step S802, that is, adjusting the brightness of the light device according to the brightness to-be-adjusted amount of the light device specifically includes:

s901: and obtaining the brightness parameters of the lighting equipment, and determining the target lighting equipment with the brightness parameters matched with the brightness to-be-adjusted quantity.

S902a: and if the current ambient light brightness is smaller than any value of the current target brightness interval and the target lighting equipment is in the off state, starting the target lighting equipment.

S902b: and if the current ambient light brightness is larger than any value of the current target brightness interval and the target lighting equipment is in an on state, the target lighting equipment is turned off.

The number of the target lighting devices may be one or plural, which is not limited in this application.

In this embodiment, the brightness parameter is used to indicate the maximum brightness of the light provided by the light device, and the brightness parameter and the brightness to-be-adjusted quantity are matched, which means that the maximum brightness indicated by the brightness parameter is equal to the brightness to-be-adjusted quantity, or the difference between the maximum brightness indicated by the brightness parameter and the brightness to-be-adjusted quantity is smaller than a preset value, where the preset value may be a value set according to actual needs, and is not limited herein. The target lighting device may be one or more, for example, the luminance to be adjusted is X Lux, and the sum of the maximum luminance when the lighting device 1, the lighting device 2, and the lighting device 3 are turned on is equal to X Lux, and then the lighting device 1, the lighting device 2, and the lighting device 3 may be determined as the target lighting device.

In particular, the luminance parameter of the light device is used to characterize the maximum luminance of the light device when it is turned on. If the current ambient light brightness is smaller than the current target brightness interval, the ambient light brightness needs to be increased, and the current ambient light brightness is adjusted to the current target brightness interval conveniently by starting the target light equipment with brightness parameters matched with the brightness to-be-adjusted quantity.

If the current ambient light brightness is larger than the current target brightness interval, the ambient light brightness needs to be reduced, and the current ambient light brightness is conveniently adjusted to the current target brightness interval by closing the target light equipment with brightness parameters matched with the brightness to-be-adjusted quantity.

Alternatively, the lighting device in steps S901, S902a, S902b may be replaced by a lighting module in the projector, and when the projector 101 is a ceiling lamp as shown in fig. 2, the lighting device may also be a lighting module in the ceiling lamp, which is not limited in this application.

Referring to fig. 10, in an alternative embodiment, in step S704b, adjusting the brightness of the lighting device and the opening/closing degree of the intelligent curtain according to the current environmental parameter and the difference value specifically includes:

s1001: and calculating a first opening and closing degree to-be-adjusted quantity of the intelligent curtain and a first brightness to-be-adjusted quantity of the lighting equipment according to the first conversion relation, the second conversion relation and the difference value corresponding to the current environmental parameters.

S1002: the opening and closing degree of the intelligent curtain is adjusted according to the first opening and closing degree to be adjusted of the intelligent curtain, and the brightness of the lighting equipment is adjusted according to the first brightness to be adjusted of the lighting equipment.

Specifically, the intelligent curtain and the lighting equipment can be combined and adjusted. For example, the difference value of any value in the current ambient light brightness and the current target brightness interval is split into a first difference value and a second difference value, wherein the first opening and closing degree adjustment amount of the intelligent curtain can be calculated based on the first difference value, and the first brightness to-be-adjusted amount of the light equipment can be calculated based on the second difference value.

It should be noted that, in the above-mentioned splitting process, if the to-be-adjusted opening/closing degree of the intelligent curtain is greater than the adjustable opening/closing degree, the change amount of the ambient light brightness corresponding to the adjustable opening/closing degree may be determined by a first conversion relationship corresponding to the current ambient parameter, the first difference value may be only smaller than or equal to the change amount of the ambient light brightness, and the second difference value may also be determined along with the determination of the first difference value. For example, the current ambient light level needs to be increased to the current target brightness interval, for example, the opening/closing degree to be adjusted is 1m, that is, the intelligent curtain needs to be opened by 1m, but the opening/closing degree adjustable is 0.5m, that is, the intelligent curtain is opened by 0.5, that is, in the fully opened state, if the opening/closing degree unit variable is 1m, the opening/closing degree adjustable is 0.5 opening/closing degree unit variable, the ambient light level variable corresponding to the 0.5 opening/closing degree unit variable can be obtained according to the first conversion relationship corresponding to the current ambient parameters, and the first difference value is only required to be less than or equal to the ambient light level variable corresponding to the 0.5 opening/closing degree unit variable. Of course, this is illustrative only and is not intended to be limiting.

The specific method for adjusting the opening and closing degree of the intelligent curtain according to the first opening and closing degree to be adjusted of the intelligent curtain and adjusting the brightness of the lighting equipment according to the first brightness to be adjusted of the lighting equipment can be referred to the foregoing embodiments, and will not be repeated herein.

As a possible way, during the operation of the projector, a real-time playing picture of the projector can be obtained; acquiring a real-time playing picture of a projection surface of a projector; counting the gray level of the real-time playing picture, and determining the brightness of the lighting equipment according to the gray level; on the premise that the ambient light brightness is matched with the current target brightness interval, when the brightness of the real-time playing picture is increased, the brightness of the light equipment is increased, and when the brightness of the real-time playing picture is reduced, the brightness of the light equipment is reduced.

For example, the gray scale from black to white may be defined as 0 to 255, 256 gray scales may be used, on the basis of which the gray scale of the real-time playing frame may be calculated, for example, the average value of the gray scales of each pixel point in the real-time playing frame is used as the gray scale of the real-time playing frame, and the gray scale of the real-time playing frame represents the brightness of the real-time playing frame, on the basis of which the brightness of the lighting device may be the product of the ratio of the brightness of the real-time playing frame to 255 and the maximum brightness of the lighting device. That is, when the real-time playing picture is completely black, the light equipment can be turned off, and when the brightness of the real-time playing picture is improved, the brightness of the light equipment can be improved on the premise that the ambient light brightness is matched with the current target brightness interval, so that on one hand, the ambient light can be kept better, and on the other hand, the more immersed ambient light atmosphere can be provided.

On the premise that the ambient light brightness is matched with the current target brightness interval, when the brightness of the real-time playing picture is increased, the brightness of the light equipment is increased, and when the brightness of the real-time playing picture is reduced, the brightness of the light equipment is reduced. Thus, the immersion and atmosphere of the user can be improved.

In a specific embodiment, the method further comprises: acquiring an image of a projection surface of a projector; determining color coordinates of each color gamut area of the projection surface according to the image of the projection surface, wherein the color coordinates are used for indicating color temperatures of the corresponding color gamut areas; and adjusting the projection color temperature of the projector according to the color coordinates of each color gamut area of the projection surface, so that the color temperature of each color gamut area is mixed with the projection color temperature of the projector to be a preset color temperature.

Color coordinates, i.e., coordinates of colors, can accurately represent colors and color temperatures. According to the method and the device for determining the color temperature of the projection, the projection color temperature of the projector is determined based on the preset color temperature and the color coordinates of each color gamut area of the projection surface, so that the color temperature of a projection picture is the preset color temperature, and the viewing experience of a user is improved.

The preset color temperature can be set according to actual needs, and the application is not limited herein.

In addition, in a specific embodiment, in step S303, the opening and closing degree of the intelligent curtain and/or the brightness of the lighting device are adjusted until the adjusted ambient light brightness matches the current target brightness interval, including:

And adjusting the opening and closing degree of the intelligent curtain and/or the brightness of the lighting equipment according to a preset stepping value, and detecting the current ambient light brightness in real time until the current ambient light brightness is within a current target brightness interval.

Optionally, in a specific embodiment, considering that the indoor environmental light brightness changes in real time, the projection control method can be executed at regular time, so that when the environmental light brightness changes in real time, the environmental light brightness can be adjusted to match with the current target brightness interval corresponding to the current working mode of the projector at regular time, thereby realizing automatic adjustment of the environmental light brightness according to the content type played by the projector, and improving the continuity and viewing experience of the user in the viewing process.

In addition, alternatively, the projector may be turned off by gradually decreasing the sound played by the projector within a preset countdown, and the light apparatus may be turned off by gradually decreasing the brightness of the light apparatus. The user can perform a countdown mode through a function button of the projector, the projector and the light equipment are completely turned off when the countdown is finished, and the preset countdown time length after the projector enters the countdown mode can be sent to the projector through a control button of the projector by the user, for example, the user presses the control button once for 10 minutes and presses the control button twice for two minutes. Of course, this is illustrative only and is not intended to be limiting.
