In the description of the present application, it should be noted that if the terms "upper", "lower", "inner", "outer", etc. are used to indicate an orientation or positional relationship based on that shown in the drawings or that the application product is usually placed in use, the description is merely for convenience and simplicity, and it is not intended to indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore should not be construed as limiting the present application.
It should be noted that the features of the embodiments of the present application may be combined with each other without conflict.
Referring to fig. 1, a flowchart of a projection implementation method provided in an embodiment of the present application is shown, where the method may be performed by a projection device. It should be understood that, in other embodiments, the order of some steps in the projection implementation method described in this embodiment may be interchanged according to actual needs, or some steps may be omitted or deleted. The detailed steps of the projection implementation method are described as follows.
Step S110, for a projection picture to be projected, determining a target projection frame corresponding to the projection picture from a plurality of pre-stored projection frames.
And step S120, forming a projection image by using the target projection frame and the projection picture, wherein the target projection frame in the projection image surrounds the periphery of the projection picture.
Step S130, projecting the projection image onto a projection surface.
When projection equipment commonly used at present projects pictures, the projection pictures generally do not have frames, and compared with some users who are used to traditional televisions for a long time, the projection equipment is difficult to adapt to the projection pictures without frames compared with the traditional television pictures with frames. In addition, in some application scenarios, for example, when a presentation is explained by projection, the existing projection screen only contains the content of the presentation itself, and some settings cannot be made to enrich the projected projection screen.
Therefore, in this embodiment, a projection implementation method is provided, in which a projection frame may be arranged at the periphery of a projection picture, so that the projection picture may have a boundary feeling, which meets the requirements of some users watching traditional television pictures with frames, and the form of the projection picture may be enriched, so that the projection picture is more various.
Optionally, a plurality of alternative projection frames may be preset, and the plurality of projection frames may include projection frames with different colors and different shapes. The preset multiple projection frames are stored in a local database or other databases in communication with the projection device, which is not limited specifically.
The projection device may obtain content information to be projected according to a user instruction, for example, the content information may be a movie, a document, or the like stored in a storage device of the projection device, or the content information may be obtained by the projection device from another system or another device through a network.
Before projection of the picture, the projection equipment can determine a target projection frame from a plurality of pre-stored projection frames for the projection picture to be projected. The target projection frame is disposed at the periphery of the projection screen to constitute a projection image, and the projection image is projected onto the projection surface, as shown in fig. 2. In this way, the projection image presented on the projection surface is an image having a projection frame on the periphery of the projection screen. The method can play the purpose of enriching the presentation form of the projection image and can aim at meeting some specific requirements of users in a targeted manner.
In this embodiment, in order to further enrich the rendering effect of the projected image, the preset projection frame may include a plurality of different frame shapes, for example, the edge of the projection frame may be flat (as shown in fig. 2), or the edge of the projection frame may be wavy (as shown in fig. 3), or the edge of the projection frame may be jagged (as shown in fig. 4). In addition, various shapes can be set according to requirements, and the embodiment is not listed.
When a target projection frame corresponding to the projection picture is determined from a plurality of pre-stored projection frames, selection information input by a user may be acquired, the selection information indicating a frame shape of the projection frame required by the user. In this way, according to the received selection information of the user, the projection frame having the frame shape indicated by the selection information can be determined from the plurality of pre-stored projection frames as the target projection frame corresponding to the projection picture.
For example, when a user wants to project an animation, the edge of the projection frame may be selected to have a wavy frame shape so that the projected image of the projected animation has a boundary feeling and the projected image has a more vivid effect. Therefore, the projection frame with wavy edge is arranged on the periphery of the projection picture, so that the projected cartoon has active presentation effect.
For another example, when the user wants to project a presentation document, the edge of the projection frame may be selected to be a flat frame shape so that the projection screen can be as concise as possible while having a sense of boundary.
In addition, besides determining the frame shape according to the selection information of the user, the projection device can automatically select the corresponding frame shape according to the content information of the projection picture to be projected.
In this embodiment, by setting the projection frame having various different frame shapes, the user can select a corresponding frame shape according to the user's own needs, and the user's diversified needs are satisfied.
In this embodiment, the purpose of providing the projection frame on the periphery of the projection screen is to make the projection screen have a boundary feeling, and if the color of the projection frame is the same as the color of the projection screen, the projection frame cannot be distinguished from the projection screen when being displayed, and the boundary feeling cannot be reflected.
Therefore, in the present embodiment, when determining the target projection frame corresponding to the projection picture from the plurality of pre-stored projection frames, in an implementation manner, the background color of the obtained projection picture may be identified, and the target projection frame corresponding to the projection picture is determined from the plurality of projection frames according to the color of each of the plurality of pre-stored projection frames.
Alternatively, the background color of the projection picture may be determined based on the pixel values of the respective pixel points by obtaining the pixel values of the respective pixel points in the projection picture. For example, the pixel values of a plurality of pixel points in the projection picture are averaged, and the color represented by the obtained pixel average is used as the background color of the projection picture.
In one implementation, each pre-stored projection frame may have a single color, for example, for a certain projection frame, each pixel point included in the projection frame is a black pixel point, or is a white pixel point. In this case, the pixel values of the pixel points of the projection frames can be directly obtained.
In order to avoid that the color of the projection frame is too close to the color of the whole projection picture and is difficult to distinguish, the projection frame with the largest difference value between the pixel value and the pixel mean value of the projection picture is selected as the target projection frame from a plurality of pre-stored projection frames based on the background color of the projection picture. In this way, the determined color of the target projection frame is greatly different from the overall color of the projection picture, and can be well distinguished.
Or screening projection frames of which the difference value between the pixel value and the pixel mean value of the projection picture is greater than a preset threshold value from the plurality of projection frames, and randomly selecting one of the screened projection frames as a target projection frame. In this way, the determined color of the target projection frame and the color of the projection picture have a large difference, and the target projection frame and the projection picture can be well distinguished.
In another implementation manner, each pre-stored projection frame may have multiple colors, for example, for a certain projection frame, the projection frame may be formed by multiple pixel points with different pixel values, that is, the projection frame is a colored projection frame. Therefore, the display effect of the projection picture can be further enriched by utilizing the colorful projection frame.
In this case, after the pixel average value of the projection picture is obtained through calculation, the pixel average value of the projection frame can be obtained through calculation according to the pixel values corresponding to the pixel points included in the projection frame for each pre-stored projection frame. And selecting the projection frame with the largest difference value between the pixel mean value and the pixel mean value of the projection picture from the plurality of projection frames as a target projection frame. Or selecting a projection frame with the difference value between the pixel mean value and the pixel mean value of the projection picture exceeding a preset threshold value from the plurality of projection frames, and randomly determining a target projection frame from the screened projection frames.
In addition, when it is considered that the background color of the adjacent projection pictures may change greatly during implementation, if color matching is performed on each frame of projection picture, the color of the projection frame changes frequently, which may affect the viewing experience. Therefore, in this embodiment, in an implementation manner, processing may be performed on a multi-frame projection picture, which is performed in the following manner with reference to fig. 5:
and step S210, identifying and obtaining the picture color of each frame of the projection picture.
Step S220, obtaining a picture color with the largest ratio of the same picture color in the multi-frame projection pictures as a background color of the multi-frame projection pictures.
In this embodiment, the determination of the projection frame may be performed by taking the multi-frame projection pictures within a period of time as a whole, and the determined projection frame is taken as a common target projection frame of the multi-frame projection pictures. The period of time may be, for example, one minute, five minutes, or the like, and the multi-frame projection picture may be, for example, 30 frames, 50 frames, or the like, and may be specifically set according to actual requirements.
In this embodiment, for each frame of the multi-frame projection picture, the picture color of the projection picture can be calculated according to the pixel values of the pixel points included in the projection picture in the above manner. Then, the color ratio of the same picture in the multiple frames of pictures is obtained, for example, for 30 frames of projection pictures, if the above processing is performed, it is determined that the pixel mean of 20 frames of projection pictures is 200, wherein the pixel mean of 5 frames of projection pictures is 150, and wherein the pixel mean of 5 frames of projection pictures is 100. The largest picture color may be used as the background color of the multi-frame projection picture, for example, the picture color represented by the pixel mean 200 is used as the background color.
On the basis, the target projection frame is determined from the plurality of pre-stored projection frames according to the background colors of the plurality of frames of projection pictures. When the projection is performed, the target projection frame may be arranged at the periphery of each of the plurality of frames of projection pictures to form a corresponding projection image, and then the projection is performed.
Therefore, by determining the target projection frame as a whole aiming at the multi-frame continuous projection pictures, the problem that the actual viewing experience is influenced due to frequent change of the projection frame during projection can be avoided.
In this embodiment, besides the color and the shape of the projection frame, the size of the projection frame may be adjusted according to requirements, for example, the width of the projection frame is adjusted. Can be great with the width adjustment of projection frame, so, can strengthen the border between projection frame and the projection picture and feel, also can be less with the width adjustment of projection frame, so, can avoid the projection frame to occupy the more position of projection picture, lead to the final area of projection picture less, influence the problem of watching the effect.
Optionally, the user may send an adjustment instruction according to a need of the user, and the projection device may adjust a size of a target projection frame and/or a projection picture included in the projection image in response to the obtained adjustment instruction.
In a possible embodiment, if the size of the projection image formed by the projection picture and the projection frame has reached the maximum size allowed, the maximum size allowed may be the maximum size of the image that can be projected by the projection device, for example, an image size corresponding to a pixel resolution of 1920 × 1080. In this case, if the size of the projection frame is to be adjusted, the size of the projection screen needs to be adjusted accordingly.
For example, when the size of the projected image has reached the maximum size allowed, the obtained adjustment instruction may be responded to increase the size of the target projection frame contained in the projected image and decrease the size of the projected picture. The size adjustment of the projection frame mainly refers to the adjustment of the width of the projection frame, and the size adjustment of the projection picture mainly refers to the adjustment of the area of the projection picture.
In this case, since the projected image has reached the maximum size allowed, when the width of the projection frame is increased, only the area of the projection screen from the inside of the projection frame can be expanded and increased, and therefore, it is necessary to reduce the area of the projection screen accordingly, as shown in fig. 6.
In addition, the size of a target projection frame contained in the projection image can be reduced and the size of the projection picture can be increased in response to the obtained adjustment instruction. In this case, when the width of the projection frame is reduced, the width can be reduced from the inside of the projection frame to the outside of the projection frame, and the area of the projection screen can be increased accordingly in order to allow the boundary of the projection screen and the boundary of the projection frame to be in contact with each other, as shown in fig. 7.
In addition, in the above case, when the width of the projection frame is reduced, the width of the projection frame may be reduced toward the outside of the projection frame, and the outside may be reduced toward the inside, so that the edge position of the inside of the projection frame does not change, and thus the area of the projection screen may be kept unchanged, as shown in fig. 8.
In another possible embodiment, if the size of the projection image formed by the projection picture and the projection frame is smaller than the maximum size allowed, in this case, the size of the target projection frame included in the projection image may be adjusted and the size of the projection picture may be kept unchanged in response to the obtained adjustment instruction.
For example, when the width of the projection frame needs to be increased in such a case, the size of the projected image does not reach the maximum allowable size, i.e., the outside of the projection frame has an expandable space. Therefore, the outer side of the projection frame can be expanded to the periphery to increase the width of the projection frame. Since the inner edge of the projection frame is not changed, the size of the projection screen can be maintained as shown in fig. 9.
In this case, when the width of the projection frame needs to be reduced, the outside or the inside of the projection frame is adjusted. For example, the outside of the projection frame can be adjusted to the inside, and in this case, the size of the projection screen can be kept unchanged, as shown in fig. 10. When the inner side of the projection frame is adjusted in the outer direction, the projection screen and the projection frame need to be in contact with each other at their boundaries, and therefore, the area of the projection screen needs to be increased, as shown in fig. 11.
In this embodiment, through the above manner, the projection frame can be adjusted in different application scenarios, and the projection picture can be correspondingly adjusted, so that the projection frame and the projection picture can be adapted in the adjusted projection picture.
In this embodiment, when the size of the projection frame or the projection screen is adjusted, the pixel points are substantially expanded based on their own pixel points.
Therefore, referring to fig. 12, in one implementation, the adjustment of the size of the target projection frame or the projection frame can be achieved by:
step S310, in response to the obtained adjustment instruction, obtains an adjusted size of the target projection frame and/or an adjusted size of the projection image, which are indicated by the adjustment instruction.
Step S320, for each pixel to be inserted determined based on the adjusted size of the target projection frame or the projection picture, calculating a pixel value of the pixel to be inserted according to a pixel value of an adjacent pixel adjacent to the pixel to be inserted, a coordinate value of each adjacent pixel, and a coordinate value of the pixel to be inserted, so as to obtain the size-adjusted target projection frame or the projection picture.
In this embodiment, the obtained adjustment instruction includes the adjusted size of the target projection frame specified by the user, or if the adjustment instruction is an adjustment instruction for the projection screen, the adjustment instruction may include the adjusted size of the projection screen. Based on the adjustment instruction, the pixel points of the target projection frame or the projection picture need to be adjusted, so that the finally adjusted target projection frame can meet the size indicated in the adjustment instruction, or the adjusted projection picture can meet the size indicated in the adjustment instruction.
In this embodiment, for the target projection frame, when adjusting the size, for example, when increasing the size of the target projection frame, a mode of additionally inserting pixel points is required, so that after the size of the target projection frame is increased, no blank pixel points appear in the image region. Therefore, based on the size to be achieved, the pixel points to be inserted can be determined, but each pixel point to be inserted is a blank pixel point. The pixel value of each pixel point to be inserted needs to be set, so that a pixel area with sudden change in the image is avoided.
For each pixel point to be inserted, adjacent pixel points of the pixel point to be inserted, for example, four adjacent pixel points of the pixel point to be inserted, namely, the upper left pixel point, the upper right pixel point, the lower left pixel point and the lower right pixel point, can be obtained. The pixel value and the coordinate value of each adjacent pixel point are known. In this case, the pixel value of the pixel point to be inserted can be calculated according to the calculation formula according to the position relationship between the pixel point to be inserted and the adjacent pixel point and the pixel value of the adjacent pixel point. Optionally, if the point to be inserted is Q (x, y), the four adjacent pixels are P1(x1, y1), P2(x1, y2), P3(x2, y1), and P4(x2, y2), respectively. The pixel values of the four adjacent pixels are known, and are f (P1), f (P2), f (P3) and f (P4). In this embodiment, the following calculation formula may be adopted to calculate the pixel value f (x, y) of the pixel point to be inserted:
