Detailed Description
The structural and operational principles of the present invention are described in detail below with reference to the accompanying drawings:
referring to FIG. 1, a block diagram of a corner display device 10 according to some embodiments of the present invention is shown. The angle display device 10 includes an angle display 11, a memory 13, and a processor 15. The processor 15 is coupled to the memory 13 and the bevel display 11. The memory 13 is used for storing one or more commands. The processor 15 is used to access and execute one or more commands of the memory 13 to perform the image compensation method of the present invention. The processor 15 may obtain a first image signal (hereinafter referred to as an original image) from an input/output device (e.g., a camera, a scanner, or a device with a universal serial bus (Universal serial bus, USB)) built in or external to the corner display device 10 (not shown), and output a second image signal (hereinafter referred to as a display image 115) to the corner display 11 after performing an image compensation method on the original image, so that the corner display 11 presents the display image 115.
In some embodiments, memory 13 is such as, but not limited to, a conventional hard disk, a solid state disk, flash memory, an optical disk, and the like. In some embodiments, the processor 15 is an arithmetic circuit such as, but not limited to, a central processing unit, a microprocessor, an Application-specific integrated circuit (ASIC), or a System-on-a-Chip (SOC).
Reference is made to fig. 2 and 3. Fig. 2 is a schematic perspective view of a corner display 11 according to some embodiments of the invention. Fig. 3 is a schematic front view of a corner display 11 according to some embodiments of the invention. The corner display 11 includes a first display surface 110, a second display surface 111, and a back plate 113. The first display surface 110 is not coplanar with the second display surface 111. For example, a corner 112 is formed between the first display surface 110 and the second display surface 111. Specifically, as shown in fig. 2 and 3, one side of the first display surface 110 is connected to one side of the second display surface 111, so that the display surface formed by the first display surface 110 and the second display surface 111 is convex. I.e. the angle 112 between the first display surface 110 and the second display surface 111 is larger than 180 degrees. In some embodiments, the first display surface 110 and the second display surface 111 may be the same shape or different shapes. The back plate 113 is located at the other side of the light emitting surfaces of the first display surface 110 and the second display surface 111, and is used for supporting the first display surface 110 and the second display surface 111.
Referring to fig. 2, 4 to 9. FIG. 4 is a flow chart of an image compensation method according to some embodiments of the invention. Fig. 5 is a schematic perspective view of the first simulation surface 20, the second simulation surface 21, and the projection surface 24 in the three-dimensional space 100 according to some embodiments of the present invention. Fig. 6 is a schematic front view of the first simulation surface 20, the second simulation surface 21, and the projection surface 24 in the three-dimensional space 100 according to some embodiments of the present invention. Fig. 7 is a schematic rear view of the first simulation surface 20, the second simulation surface 21, and the projection surface 24 in the three-dimensional space 100 according to some embodiments of the present invention. Fig. 8 is a schematic perspective view of the first simulation surface 20, the second simulation surface 21, and the projection surface 24 in the three-dimensional space 100 according to some embodiments of the present invention. Fig. 9 is a schematic front view of the first simulation surface 20, the second simulation surface 21, and the projection surface 24 in the three-dimensional space 100 according to some embodiments of the present invention. In some embodiments, the one or more commands executed by the processor 15 include steps S601 to S609 to implement the image compensation method. First, the processor 15 simulates the first display surface 110 and the second display surface 111 to respectively create the first simulation surface 20 and the second simulation surface 21 in the three-dimensional space 100 (step S601). Since the first simulation surface 20 and the second simulation surface 21 simulate the first display surface 110 and the second display surface 111, the first simulation surface 20 and the second simulation surface 21 are not coplanar. For example, the processor 15 may define a three-dimensional coordinate system (e.g., rectangular coordinate system) of the three-dimensional space 100 by using a certain portion of the angular display 11 as a reference point. The processor 15 obtains a first three-dimensional coordinate parameter set of the three-dimensional coordinate system according to the relative positions between the reference point and the first display surface 110 (e.g., four boundary points thereof), and obtains a second three-dimensional coordinate parameter set of the three-dimensional coordinate system according to the relative positions between the reference point and the second display surface 111 (e.g., four boundary points thereof). The first three-dimensional coordinate parameter set and the second three-dimensional coordinate parameter set may respectively include a plurality of three-dimensional coordinate parameters. In some embodiments, the three-dimensional coordinate parameters may be expressed in terms of (x, y, z), where x is the horizontal axis value of the three-dimensional coordinate system, y is the vertical axis value of the three-dimensional coordinate system, and z is the vertical axis value of the three-dimensional coordinate system. The processor 15 can respectively create the first simulation surface 20 and the second simulation surface 21 in the three-dimensional space 100 according to the first three-dimensional coordinate parameter set and the second three-dimensional coordinate parameter set.
In some embodiments, in addition to the first display surface 110 and the second display surface 111, the processor 15 may simulate other elements of the angular display 11 or the whole of the angular display 11 to create a corresponding model in the three-dimensional space 100. For example, as shown in fig. 5 and 8, the processor 15 may also simulate the back plate 113 of the angled display 11 to create the back plate model 23 in the three-dimensional space 100.
Next, the processor 15 establishes a projection surface 24 in the three-dimensional space 100 (step S603). For example, as shown in fig. 5 and 7, the projection surface 24 is located on the rear side of the back plate model 23 as compared to the first simulation surface 20 and the second simulation surface 21 which are located on the front side of the back plate model 23. However, the present invention is not limited thereto, and for example, as shown in fig. 8 and 9, the projection surface 24, the first simulation surface 20, and the second simulation surface 21 are all located on the same side (front side) of the back plate model 23. In some embodiments, the projection surface 24 is planar or curved.
As shown in fig. 4 and 5, after the first simulation surface 20, the second simulation surface 21, and the projection surface 24 are established, the processor 15 projects the original image onto the projection surface 24 to form the first projection image 30 (step S605). For example, the processor 15 may align the center point of the original image with the center point of the projection surface 24, and project each pixel onto a corresponding three-dimensional coordinate parameter (hereinafter referred to as a projection surface coordinate parameter) of the projection surface 24 in the three-dimensional coordinate system of the three-dimensional space 100 according to the pixel coordinate parameter of each pixel of the original image, so as to form the first projection image 30. That is, the processor 15 may directly project the original image to the projection surface 24 to form the first projection image 30. Specifically, the processor 15 may convert the original image into the first projection image 30 according to a first conversion function, where the first conversion function may be represented as formula 1, pv is the first conversion function, vo is a matrix of pixel coordinate parameters of pixels of the original image, and Mvtran is a conversion matrix that converts the pixel coordinate parameters into projection plane coordinate parameters of the projection plane 24.
Pv=vo×mvtran (formula 1)
As shown in fig. 4 to 6, after forming the first projection image 30, the processor 15 projects (parallel projection) the first projection image 30 in parallel toward the viewing position 40 to the first analog surface 20 and the second analog surface 21 to form the second projection image 31 (step S607). For example, the processor 15 may convert the first projection image 30 into the second projection image 31 according to a second conversion function, where the second conversion function may be represented as formula 2, ps is the second conversion function, pv is the conversion function (e.g. the first conversion function or a third conversion function described later) performed in step S605, mob is a conversion matrix of parallel projection, and Mtran is a conversion matrix of parallel projection for converting the projection plane coordinate parameters after parallel projection processing into corresponding three-dimensional coordinate parameters (hereinafter referred to as analog plane coordinate parameters) of the first analog plane 20 and the second analog plane 21 in the three-dimensional coordinate system of the three-dimensional space 100.
Ps=pv×mob×mtran (formula 2)
In some embodiments, the parallel projections include orthographic projections (orthographic projection) and oblique projections (oblique projection). In some embodiments of step S607, the projection method for projecting the first projection image 30 onto the first analog surface 20 and the second analog surface 21 according to the different viewing positions 40 and the distribution positions of the first projection image 30 on the projection surface 24 may be one or both of front projection and oblique projection.
Reference is made to fig. 4, 6, 10 and 11. Fig. 10 is a schematic front view of a corner display 11 according to a comparative example of the present invention. Fig. 11 is a front view of a corner display 11 according to some embodiments of the invention. After forming the second projection image 31, the processor 15 forms a display image 115 on the first display surface 110 and the second display surface 111 according to the first analog surface 20, the second analog surface 21 and the second projection image 31 (step S609). For example, since the first simulation surface 20 and the second simulation surface 21 simulate the first display surface 110 and the second display surface 111, the processor 15 can control the first display surface 110 and the second display surface 111 to present the second projection image 31 as the display image 115 according to the simulation surface coordinate parameters and the pixels corresponding to the original image. In this way, compared to the case where the original image is presented as the display image 116 (as shown in fig. 10) on the first display surface 110 and the second display surface 111, the second projection image 31 is presented as the display image 115 (as shown in fig. 11) on the first display surface 110 and the second display surface 111, the pattern of the display image 115 can have a stereoscopic impression, and the pattern is not affected by the folding angle 112 but has continuity. In addition, the second projected image 31 as the display image 115 is not visually deformed by the different viewing positions 40 (for example, the viewer views the angled display 11 in a top view position or views the angled display 11 in a bottom view position).
Reference is made to fig. 12 and 13. Fig. 12 is a schematic perspective view of the first simulation surface 20, the second simulation surface 21, and the projection surface 24 in the three-dimensional space 100 according to some embodiments of the present invention. FIG. 13 is a flowchart of an image compensation method according to some embodiments of the invention. In some embodiments of step S605, the processor 15 projects the original image onto the first analog surface 20 and the second analog surface 21 to form a third projection image 32 (step S6051), and orthographically projects the third projection image 32 onto the projection surface 24 to form the first projection image 30 (step S6052). Since the first simulation surface 20 and the second simulation surface 21 simulate the first display surface 110 and the second display surface 111, the processor 15 can simulate the case of directly presenting the original image as the display image 116 (as shown in fig. 10) on the first display surface 110 and the second display surface 111 through the third projection image 32 formed by projecting the original image onto the first simulation surface 20 and the second simulation surface 21. For example, the processor 15 may determine the original image based on the pixel coordinate parameters of each pixel of the original image at the positions of the first display surface 110 and the second display surface 111 when the original image is directly presented on the first display surface 110 and the second display surface 111The initial image is projected onto the simulated surface coordinate parameters of the first simulated surface 20 and the second simulated surface 21 to form a third projected image 32. Next, the processor 15 orthographically projects the third projection image 32 onto the projection surface 24 to form a first projection image 30. That is, the processor 15 may indirectly project the original image to the projection surface 24 to form the first projection image 30. Specifically, the processor 15 may convert the original image into the first projection image 30 according to a third conversion function, where the third conversion function may be represented as formula 3, P v Is a third transformation function, vo is a matrix of pixel coordinate parameters of pixels of the original image, mort is a transformation matrix of orthographic projection, M v tr a n is a conversion matrix for converting the pixel coordinate parameters after the orthographic projection process into projection plane coordinate parameters of the projection plane 24. In this way, the first projected image 30 formed by indirectly projecting the original image onto the projection surface 24 can be more similar to the actual display state of the first display surface 110 and the second display surface 111 of the angled display 11 than the case of directly projecting the original image onto the projection surface 24, so as to ensure that the second projected image 31 as the display image 115 is not visually deformed.
Pv=vo x Mort x Mvtran (formula 3)
In some embodiments, the size of the projection surface 24 may be determined according to the sizes of the first simulation surface 20 and the second simulation surface 21. For example, the size of the projection surface 24 is determined by two sides defined by the joint between the first simulation surface 20 and the second simulation surface 21 being displaced to two sides by a distance. The different projection surfaces 24 may be sized to provide different degrees of stereoscopic perception to the second projected image 31 as the display image 115. For example, when the distance by which the joining edge is displaced to both sides is small, the size of the projection surface 24 is small and the second projection image 31 has a visually far effect; when the distance by which the joint edge is displaced to both sides is large, the size of the projection surface 24 is large and the second projection image 31 has a visual close effect.
Reference is made to fig. 7 and 14. Fig. 14 is a schematic rear view of the first simulation surface 20, the second simulation surface 21, and the projection surface 24 in the three-dimensional space 100 according to some embodiments of the present invention. In some embodiments, two sides (i.e., a first side 241 and a second side 242) of the projection surface 24 are respectively connected to the first analog surface 20 and the second analog surface 21. As shown in fig. 7, in the first exemplary embodiment, one of the two sides (i.e., the first side 241) of the projection surface 24 is connected to the area between the two sides (i.e., the third side 201 and the fourth side 202) of the first analog surface 20, and the other one of the two sides (i.e., the second side 242) of the projection surface 24 is connected to the area between the two sides (i.e., the fifth side 211 and the sixth side 212) of the second analog surface 21. Wherein, the distance between the first side 241 and the third side 201 and the distance between the first side 241 and the fourth side 202 may be the same as or different from the distance between the second side 242 and the fifth side 211 and the distance between the second side 242 and the sixth side 212, respectively. As shown in fig. 14, in the second exemplary embodiment, one of the two sides (i.e., the first side 241) of the projection surface 24 is connected to one of the two sides (i.e., the third side 201) of the first analog surface 20, the other of the two sides (i.e., the second side 242) of the projection surface 24 is connected to one of the two sides (i.e., the fifth side 211) of the second analog surface 21, the other of the two sides (i.e., the fourth side 202) of the first analog surface 20 is connected to the other of the two sides (i.e., the sixth side 212) of the second analog surface 21, that is, the fourth side 202 and the sixth side 212 are joint edges. In the second example, the projection surface 24 is larger in size than in the first example.
As shown in fig. 5 and 7, in some embodiments, the viewing position 40 is calculated according to the distance between two sides (i.e., the third side 201 and the fourth side 202) of the first analog surface 20, the distance between two sides (i.e., the fifth side 211 and the sixth side 212) of the second analog surface 21, the viewing angle, and the angle of refraction 50 between the first analog surface 20 and the second analog surface 21. Here, the folded angle 50 is an angle formed by the other sides of the light-emitting surfaces of the first display surface 110 and the second display surface 111. The viewing angle is the line of sight of the eyes of the viewer. In some embodiments, the angle of refraction 50 between the first analog face 20 and the second analog face 21 is less than 180 degrees. In some embodiments, the viewing angle is between 20 degrees and 30 degrees. For example, assuming that the first simulation surface 20 and the second simulation surface 21 have the same size (i.e., the distance between the third side 201 and the fourth side 202 of the first simulation surface 20 is the same as the distance between the fifth side 211 and the sixth side 212 of the second simulation surface 21), the processor 15 may calculate the three-dimensional coordinate parameters of the viewing position 40 in the three-dimensional coordinate system of the three-dimensional space 100 according to the viewing position function. The viewing position function can be expressed as formula 4, where L1 is the distance between the viewing position 40 and the fourth side 202 (or the sixth side 212), L2 is the distance between the central axis between the third side 201 and the fifth side 211 and the fourth side 202 (or the sixth side 212), L3 is the distance between the third side 201 and the fourth side 202 of the first analog surface 20 (or the distance between the fifth side 211 and the sixth side 212 of the second analog surface 21), θa is the half value of the angle 50 between the first analog surface 20 and the second analog surface 21, and θb is the half value of the viewing angle.
Referring to fig. 15, a perspective view of a corner display 11 according to some embodiments of the invention is shown. In some embodiments, the corner display 11 further includes a third display surface 114 connected between the first display surface 110 and the second display surface 111. In some embodiments, the third display surface 114 is non-coplanar with the first display surface 110, and the third display surface 114 is non-coplanar with the second display surface 111. For example, the first display surface 110 and the third display surface 114 have a first folding angle 112A therebetween, and the second display surface 111 and the third display surface 114 have a second folding angle 112B therebetween. Specifically, two sides of the third display surface 114 are respectively connected to one side of the first display surface 110 and one side of the second display surface 111, so that the display surfaces formed by the first display surface 110, the second display surface 111 and the third display surface 114 are convex. That is, the first and second corners 112A and 112B are corners greater than 180 degrees. In some embodiments, the back plate 113 is located at the other side of the light emitting surfaces of the first display surface 110, the second display surface 111 and the third display surface 114, and is used for supporting the first display surface 110, the second display surface 111 and the third display surface 114.
Refer to fig. 16 and 17. Fig. 16 is a schematic perspective view of the first simulation surface 20, the second simulation surface 21, the third simulation surface 25, and the projection surface 24 in the three-dimensional space 100 according to some embodiments of the present invention. FIG. 17 is a flowchart of an image compensation method according to some embodiments of the invention. In some embodiments, the one or more commands executed by the processor 15 include steps S1601-S1609 to implement the image compensation method. Since steps S1601, S1603, S1605 are identical to steps S601, 603, 605, the description thereof will not be repeated here. In step S1602, the processor 15 simulates the third display surface 114 to create a third simulation surface 25 connected between the first simulation surface 20 and the second simulation surface 21 in the three-dimensional space 100. In some embodiments, since the first simulation surface 20, the second simulation surface 21, and the third simulation surface 25 are simulated from the first display surface 110, the second display surface 111, and the third display surface 114, the third simulation surface 25 is not coplanar with the first simulation surface 20, and the third simulation surface 25 is not coplanar with the second simulation surface 21. For example, the processor 15 obtains a third three-dimensional coordinate parameter set of the three-dimensional coordinate system of the three-dimensional space 100 according to the relative positions between the reference point and the third display surface 114 (e.g., four boundary points thereof). Wherein the third set of three-dimensional coordinate parameters may comprise a plurality of three-dimensional coordinate parameters. The processor 15 can create the third simulation surface 25 in the three-dimensional space 100 according to the third three-dimensional coordinate parameter set.
In some embodiments, the projection surface 24 is located on the rear side of the back plate model 23 as compared to the first, second and third simulation surfaces 20, 21 and 25 located on the front side of the back plate model 23. However, the present invention is not limited to this, and the projection surface 24, the first simulation surface 20, the second simulation surface 21, and the third simulation surface 25 are all located on the same side (front side) of the back plate model 23.
The difference from step S607 is that, in step S1607, the processor 15 projects the first projection image 30 to the third simulation surface 25 in parallel to the viewing position 40 in addition to the first simulation surface 20 and the second simulation surface 21 in parallel to the viewing position 40, that is, the processor 15 projects the first projection image 30 to the first simulation surface 20, the second simulation surface 21 and the third simulation surface 25 in parallel to the viewing position 40 to form the second projection image 31. For example, the processor 15 may convert the first projection image 30 into the second projection image 31 according to the aforementioned second conversion function. In the present embodiment, mtran converts the projection plane coordinate parameters after the parallel projection processing into three-dimensional coordinate parameters (i.e., simulated plane coordinate parameters) corresponding to the three-dimensional coordinate system of the first simulated plane 20, the second simulated plane 21, and the third simulated plane 25 in the three-dimensional space 100. In some embodiments, parallel projections include orthographic projections and oblique projections. Therefore, in some embodiments of step S1607, the projection method of the first projection image 30 onto the first analog surface 20, the second analog surface 21 and the third analog surface 25 may be one or both of front projection and oblique projection according to different viewing positions 40 and distribution positions of the first projection image 30 on the projection surface 24.
The difference from step S609 is that in step S1609, the processor 15 considers the third simulation surface 25 in addition to the first simulation surface 20, the second simulation surface 21 and the second projection image 31, that is, the processor 15 forms the display image 115 on the first display surface 110, the second display surface 111 and the third display surface 114 according to the first simulation surface 20, the second simulation surface 21, the third simulation surface 25 and the second projection image 31. For example, since the first analog surface 20, the second analog surface 21 and the third analog surface 25 are simulated from the first display surface 110, the second display surface 111 and the third display surface 114, the processor 15 can control the first display surface 110, the second display surface 111 and the third display surface 114 to present the second projection image 31 as the display image 115 according to the analog surface coordinate parameters of the first analog surface 20, the second analog surface 21 and the third analog surface 25 and the pixels corresponding to the original image. Thus, the pattern of the display image 115 can have a stereoscopic effect, and the pattern has continuity without being affected by the folded angle 112. In addition, the display image 115 is not visually distorted by the different viewing positions 40.
Referring to fig. 18, a flowchart of an image compensation method according to some embodiments of the invention is shown. In some embodiments of step S1605, the processor 15 projects the original image onto the first analog surface 20, the second analog surface 21 and the third analog surface 25 to form a third projected image 32 (step S16051), and orthographically projects the third projected image 32 onto the projection surface 24 to form the first projected image 30 (step S16052). For example, the processor 15 may project the original image onto the analog plane coordinate parameters of the first analog plane 20, the second analog plane 21 and the third analog plane 25 to form the third projection image 32 according to the pixel coordinate parameters of each pixel of the original image at the positions of the first display plane 110, the second display plane 111 and the third display plane 114 when the original image is directly presented on the first display plane 110, the second display plane 111 and the third display plane 114. Next, the processor 15 orthographically projects the third projection image 32 onto the projection surface 24 to form a first projection image 30. In particular, the processor 15 may convert the original image into the first projection image 30 according to the aforementioned third conversion function. In this way, the second projection image 31 as the display image 115 can be ensured to be similar to the actual display states of the first display surface 110, the second display surface 111, and the third display surface 114, and no visual distortion occurs.
In summary, according to the embodiments of the present invention, the display image of the folded angle display may have a stereoscopic effect. In addition, the invention can ensure that the display image of the folded angle display has continuity without being influenced by the folded angle.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
