[0004] During projector use, users can adjust parameters such as brightness, saturation, and color to achieve their preferred display effect. Currently, on the one hand, users typically use the default image mode; on the other hand, while some users may adjust the display parameters according to personal preferences, directly adjusting these parameters is too complex and not intuitive for the average user. Therefore, the current display effect cannot satisfy all user groups, resulting in a poor viewing experience and failing to create a personalized projection experience. Summary of the Invention

[0020] Hue, color temperature, screen brightness, gamma, contrast, sharpness, saturation, or color gamut;
[0021] The parameters for each group of images are different.
[0022] In one possible implementation, each group of images corresponds to at least two different parameter dimensions.
[0023] In one possible implementation, each image in each group of images has different content but the same style.
[0024] Accordingly, embodiments of this application also provide a projection device, which includes:
[0025] The application module is used to control the display module to display multiple sets of images. Any two sets of images in the multiple sets of images have different parameter dimensions. Each set of images includes at least two images with the same parameter dimensions but different parameters corresponding to those parameters.
[0026] The display module is used to display the multiple sets of images;

[0028] The display module is also used to display the user's preferred projection effect according to the parameters corresponding to the parameter dimensions of each image.
[0029] In one possible implementation, the projection device further includes a display frame module; the display module is used to display a user-preferred projection effect based on parameters corresponding to the parameter dimensions of each image, including:
[0030] The display frame module is used to determine the index value corresponding to each image;
[0031] The display framework module is also used to call the parameters of the corresponding effect according to the index value of each image;
[0032] The display module is used to display the projection effect preferred by the user according to the parameters.
[0033] In one possible implementation, the display frame module is used to determine the index value of each image, including:
[0034] The display frame module is used to determine the sequence of each image;

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0054] In the description of this application, it should be understood that the terms "a" and "an" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "a" or "an" may explicitly or implicitly include one or more features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0055] In this application, the term "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0056] Figure 1 is a flowchart illustrating an example of a projection method provided in an embodiment of this application. As shown in Figure 1, the method includes:
[0057] S110 controls the projection device to display multiple sets of images.
[0058] In this embodiment of the application, any two groups of images in the multiple groups of images have different parameter dimensions, and each group of images in the multiple groups of images includes at least two images with the same parameter dimensions but different parameters corresponding to the parameter dimensions.
[0059] In one possible implementation, the projection device can be controlled to display multiple sets of images simultaneously. This allows the user to directly select an image from the multiple sets of images displayed on the projection device, thus saving the user's time. In another possible implementation, the projection device can be controlled to display each set of images sequentially. This allows the user to select their preferred image from each set sequentially, without being disturbed by other sets of images, making the selected image more accurately reflect the user's preferences. Alternatively, for example, the projection device can be controlled to display two sets of images sequentially, or three sets of images sequentially, and so on. This application does not limit the implementation in this way. This solution can save the user's time as much as possible while ensuring that the selected image relatively accurately reflects the user's preferences.
[0060] In this embodiment, the parameter dimension may include at least one of the following: hue, color temperature, image brightness, gamma, contrast, sharpness, saturation, or color gamut. It should be understood that the parameter dimension may also include other dimensions, and this embodiment does not limit this. The parameters corresponding to the parameter dimension in this embodiment can be referred to in the following examples.
[0061] For example, the parameter dimension is hue, and the parameters corresponding to the parameter dimension can be hue normal, hue reddish, hue bluish, etc.
[0062] For example, the parameter dimension is color temperature, and the parameters corresponding to the parameter dimension can be color temperature standard, warm color temperature, cool color temperature, etc.
[0063] For example, the parameter dimension is screen brightness, and the parameter corresponding to the parameter dimension can be the screen brightness value, such as 40, 50, 60, etc.
[0064] For example, the parameter dimension is gamma, and the parameter corresponding to the parameter dimension can be a gamma value, such as 2.2, 2.6.1.8, etc.
[0065] For example, the parameter dimension is contrast, and the parameter corresponding to the parameter dimension can be the value of contrast, such as 45, 50, 60, etc.
[0066] For example, the parameter dimension is sharpness, and the parameter corresponding to the parameter dimension can be a sharpness value, such as 50, 35, 65, etc.
[0067] For example, the parameter dimension is saturation, and the parameter value corresponding to the parameter dimension is the saturation value, such as 50, 40, 60, etc.
[0068] For example, the parameter dimension is color gamut, and the parameters corresponding to the parameter dimension can be, for example, PCI-P3, BT.709, BT.2020, etc.
[0069] In this embodiment of the application, each group of images in the multiple groups of images may have only one parameter dimension that is different, or two parameter dimensions that are different, or more than two parameter dimensions that are different. This embodiment of the application does not limit this and will not list them one by one.
[0070] In one possible implementation, the content of each image in each group can be different, while the style can be the same. For example, each image in the first group could be a pencil, a pen, a brush, etc., meaning the first group of images has the same style (all are pen-related), but the content of each image differs, representing different types of pens. This approach avoids situations where users select images that don't accurately reflect their preferences due to guessing the projection device's intention.
[0071] In another possible implementation, each image in each group can have the same content and style; only the parameters corresponding to the parameter dimensions differ. For example, each image in the first group could be a pencil with a normal tone, a pencil with a bluish tone, and a pencil with a reddish tone, in that order. This approach reduces the difficulty of selection for users and saves them time.
[0072] Alternatively, as a possible implementation, the content and style of each image in each group of images can be different, and this application does not limit this.
[0073] S120: Confirm the multiple images selected by the user.
[0074] In this embodiment of the application, the multiple images selected by the user are one image from each of the multiple sets of images; that is, the user can select one image from each set of images.
[0075] Alternatively, as another possible implementation, the user can arbitrarily select multiple images from the multiple images included in the multiple sets of images; this application embodiment does not limit this.
[0076] S130 displays the user-preferred projection effect based on the parameters corresponding to the parameter dimensions of each of the multiple images selected by the user.
[0077] Optionally, as shown in Figure 2, step S130 involves displaying the user-preferred projection effect based on the parameters corresponding to the parameter dimensions of each of the multiple images selected by the user, including:
[0078] S131, determine the index value corresponding to each of the multiple images selected by the user.
[0079] Optionally, as shown in Figure 3, step S131 involves determining the index value of each image among the multiple images selected by the user, including:
[0080] S1311, Determine the sequence of each image among the multiple images selected by the user;
[0081] In this embodiment of the application, the sequence of each image can also be the label of each image, or the serial number of each image. This embodiment of the application does not limit this.
[0082] S1312, based on the sequence of each image among the multiple images selected by the user, determine the index value of each image using a preset algorithm.
[0083] The preset algorithm can be a logical algorithm or other algorithms, and this application embodiment does not limit it.
[0084] S132, call the parameters of the corresponding effect based on the index value of each of the multiple images selected by the user.
[0085] In this embodiment, a pre-defined correspondence between index values and corresponding effect parameters can be established, allowing the corresponding effect parameters to be called via the index value. For example, the index values and effect parameters can be mapped using a matrix, or other methods can be employed. The mapping can be one-to-one or one-to-many; this embodiment does not limit the specific mapping.
[0086] S133 displays the user's preferred projection effect based on parameters.
[0087] Specifically, the system displays the user's preferred projection effect based on the parameters corresponding to the desired effect.
[0088] The above steps will be fully explained below through a specific embodiment.
[0089] In this example, there can be four sets of images, with each set consisting of three images. Of course, the number of sets and the number of images in each set can be other values, and this embodiment does not limit this.
[0090] In this example, each group of images corresponds to two parameter dimensions, or in other words, each group of images has two strongly correlated parameter dimensions. The strong correlation between these two parameter dimensions is explained as follows: For the first group of images in Table 1, normal hue and standard color temperature are strongly correlated, reflecting neutral hue and color temperature; reddish hue and warm color temperature are strongly correlated, reflecting warm hue and warm color temperature; bluish hue and cool color temperature are strongly correlated, reflecting cool hue and cool color temperature. Similarly, for the second group of images in Table 1, a brightness of 50 and a gamma value of 2.2 are strongly correlated, reflecting comfortable brightness and gamma value; a brightness of 40 and a gamma value of 2.6 are strongly correlated, reflecting soft brightness and gamma value; and a brightness of 60 and a gamma value of 1.8 are strongly correlated, reflecting bright brightness and gamma value. Aamma value; for example, in the third group of images in Table 1, a contrast value of 50 and a sharpness value of 50 are strongly correlated, reflecting clear contrast and sharpness; a contrast value of 45 and a sharpness value of 35 are strongly correlated, reflecting transparent contrast and sharpness; a contrast value of 60 and a sharpness value of 65 are strongly correlated, reflecting sharp contrast and sharpness. For another example, in the fourth group of images, a saturation value of 50 and a color gamut of PCI-P3 are strongly correlated, reflecting natural saturation and color gamut; a saturation value of 40 and a color gamut of BT.709 are strongly correlated, reflecting standard saturation and color gamut; a saturation value of 60 and a color gamut of BT.2020 are strongly correlated, reflecting vibrant saturation and color gamut. In other words, the above effects can also be described as strong, medium, and weak effects, meaning that the final images presented in Table 1 have 3*3*3*3=81 effects.
[0091] The projection method includes:
[0092] Step 1: The projection device displays multiple sets of images in sequence.
[0093] Referring to Table 1, each group of images corresponds to two parameter dimensions. As shown in Table 1, the parameter dimensions for the first group of images are hue and color temperature. Image 1 in the first group has a normal hue and standard color temperature; Image 2 has a reddish hue and warm color temperature; and Image 3 has a bluish hue and cool color temperature. The parameter dimensions for the second group of images are brightness and gamma. Image 1 in the second group has a brightness of 50 and a gamma of 2.2; Image 2 has a brightness of 40 and a gamma of 2.6; and Image 3 has a brightness of 60 and a gamma of 1.8. The parameter dimensions for the third group of images are contrast and sharpness. Image 1 in the third group has a contrast of 50 and a sharpness of 50; Image 2 has a contrast of 45 and a sharpness of 35; and Image 3 has a contrast of 60 and a sharpness of 65. The parameter dimensions for the fourth group of images are saturation and color gamut. Image 1 in the fourth group has a saturation of 50 and a color gamut of DCI-P3; Image 2 has a saturation of 40 and a color gamut of BT.709; and Image 3 has a saturation of 60 and a color gamut of BT.2020.
[0094] Table 1
[0095] In this embodiment, the optical engine of the projection device can project four sets of images onto the display module of the projection device. The four sets of images have different styles and different content, as described in the above embodiments, and will not be repeated here.
[0096] Step 2: Determine the multiple images selected by the user.
[0097] For example, the user selected image 1 from the first group of images, image 2 from the second group of images, image 1 from the third group of images, and image 2 from the fourth group of images.
[0098] In this example, for instance, the second set of images will only be shown to the user after the user selects one image from the first set, and so on. The third set of images will only be shown to the user after the user selects one image from the second set, and so on, until the user has selected all four images in sequence.
[0099] In this embodiment, the application module of the projection device can record the sequence of images selected by the user throughout the process, and then send the sequence of images selected by the user back to the display frame module.
[0100] Step 3: Determine the sequence of each image selected by the user.
[0101] In this embodiment, the display frame module of the projection device determines the sequence of images selected by the user.
[0102] Step 4: Determine the index value of each image based on the sequence of images selected by the user using a preset algorithm.
[0103] In this embodiment, the display frame module of the projection device can determine the index value of each image based on the sequence of each image using a logical algorithm.
[0104] Step 5: Call the parameters of the corresponding effect based on the index value of each image.
[0105] In this embodiment, the application module of the projection device can call the parameters corresponding to the effect based on the index value calculated by the display frame module.
[0106] See Table 2 for the array of parameters and their calling relationships.
[0107] Table 2
[0108] In the embodiments of this application, taking the MTK chip as an example, the parameters in Table 2 above can be written into the effect file using the MTK chip. When the display frame module sends the index value to call the interface, the display effect can be achieved by calling the parameters debugged by the MTK according to the logic, resulting in a better display experience.
[0109] Step 6: Display the projection effect according to the user's preference based on the parameters.
[0110] Furthermore, the application module of the projection device can control the display module to display the projection effect preferred by the user according to the parameters of the corresponding effect.
[0111] The projection method provided in this application embodiment can control a projection device to display multiple sets of images. Any two sets of images in the multiple sets of images have different parameter dimensions, and each set of images includes at least two images with the same parameter dimensions but different corresponding parameters. Furthermore, the projection device can determine the multiple images selected by the user, which are the images selected by the user from each set of images. Then, the projection device can display the user-preferred projection effect or a user-specific projection effect based on the parameters corresponding to the parameter dimensions of each image selected by the user. In this solution, the user only needs to select their preferred image without complex parameter adjustments to enable the projection device to display the user-preferred effect. Therefore, this solution can improve the user experience, enhance the viewing experience of the projector, and create a user-specific display effect.
[0112] To facilitate better implementation of the projection method of this application, this application also provides a projection device based on the above projection method. The meanings of the terms used are the same as in the projection method described above, and specific implementation details can be found in the description of the method embodiments.
[0113] Please refer to Figure 4, which is a schematic diagram of the projection device provided in an embodiment of this application. The device can be specifically as follows:
[0114] Application module 410 is used to control display module 420 to display multiple sets of images, wherein any two sets of images in the multiple sets of images have different parameter dimensions, and each set of images in the multiple sets of images includes at least two images with the same parameter dimensions but different parameters corresponding to the parameter dimensions.
[0115] The display module 420 is used to display the multiple sets of images;
[0116] The application module 410 is also used to determine the multiple images selected by the user, wherein each image in the multiple images is one of the images in each group of multiple images;
[0117] The display module 420 is also used to display the user's preferred projection effect according to the parameters corresponding to the parameter dimensions of each image.
[0118] In one possible implementation, the projection device further includes a display frame module 430; the display module 420 is used to display a user-preferred projection effect according to the parameters corresponding to the parameter dimensions of each image, including:
[0119] The display frame module 430 is used to determine the index value corresponding to each image;
[0120] The display frame module 430 is also used to call the parameters of the corresponding effect according to the index value of each image;
[0121] The display module 420 is used to display the projection effect preferred by the user according to the parameters.
[0122] In one possible implementation, the display frame module 430 is used to determine the index value of each image, including:
[0123] The display frame module 430 is used to determine the sequence of each image;

[0126] The application module 410 is used to control the display module to sequentially display each of the multiple sets of images.
[0127] In one possible implementation, each of the multiple sets of images displayed sequentially by the display module 420 corresponds to at least one of the following parameter dimensions:
[0128] Hue, color temperature, screen brightness, gamma, contrast, sharpness, saturation, or color gamut;
[0129] The parameters for each group of images are different.
[0130] In one possible implementation, each group of images corresponds to at least two different parameter dimensions.
[0131] In one possible implementation, each image in each group of images has different content but the same style.
[0132] The projection device provided in this application embodiment allows the application module 410 to control the display module 420 to display multiple sets of images. Any two sets of images in these multiple sets have different parameter dimensions, and each set includes at least two images with the same parameter dimensions but different corresponding parameters. Furthermore, the application module 410 can determine the multiple images selected by the user, which are the images selected by the user from each set of images. Then, the display module 420 can display the user-preferred projection effect or a user-specific projection effect based on the parameters corresponding to the parameter dimensions of each image selected by the user. In this solution, the user only needs to select their preferred image without complex parameter adjustments to enable the display module 420 to display the user-preferred effect. Therefore, this solution can improve the user experience, enhance the viewing effect of the projector, and create a user-specific display effect.
