(A)
In order to achieve the above object, an embodiment of the present invention provides an ultra-wide frame fusion display method, which includes: cutting the ultra-wide multimedia source into a plurality of picture blocks; and in the display size range of the display device, taking the width value of the resolution of the ultra-wide multimedia source as a picture block cutting width value; in the multimedia interface display size range, equally dividing the length value of the resolution of the ultra-wide multimedia source as the picture block cutting length value; sequentially layering the drawing blocks to recombine into an output drawing source which accords with the display size range of the multimedia interface; and each display device acquires the output drawing source, respectively displays the drawing block areas corresponding to the display device in the output drawing source, and splices the drawing block areas into a fusion display.
The display device in the invention is preferably a projector, but can also be a display screen or various prior art display devices which can be spliced.
Furthermore, in this embodiment, the ultra-wide multimedia source is preferably designed to match the range of the screen size that can be output by the multimedia interface during the manufacturing process, that is, in this embodiment, under the condition that the fusion tape is not considered, the width value of the range of the screen size that can be output by the multimedia interface and the width value of the ultra-wide multimedia source are preferably in an integral multiple relationship, and meanwhile, the length value of the ultra-wide multimedia source can also be in an integral multiple relationship with the length value of the range of the screen size that can be output by the multimedia interface, for example, when the HDMI interface is adapted (the maximum 4K resolution supported by HDMI is 3840x2160) and the ultra-wide multimedia source is 5760x1080 resolution, the width value, that is, 1080 size of the ultra-wide multimedia source can be used as the cutting width value of the picture block, and at most two layers of picture blocks can be set, and the cutting length value of the block is adjusted according to the maximum supported size of the current adapted multimedia interface, for example, in the HDMI interface, the length value of the cut block of the block needs to be smaller than 3840, and the length value can be distributed evenly or freely according to the number of the devices shown, for example, in this embodiment, the cut block is preferably cut evenly, i.e. the cut block is cut into 2880x1080 and two layers are stacked as in fig. 1, so that the 2880x2160 output frame source 3 can be obtained to be displayed in the full resolution range supported by the HDMI interface.
Therefore, after the 2 cut Picture blocks are matched with the two corresponding projectors, the intercepting window is opened preferably through the PIP function (Picture In Picture In Picture) of the projectors, so that the Picture blocks corresponding to the projectors In the output Picture source are positioned and spliced, and fusion display can be completed.
In addition, on the other hand, if the maximum display size range of the projector is smaller than that of the picture block, if the length value is not enough, the projected picture block area can be filled in by adding the number of projectors, for example, 2 projectors simultaneously project the picture block a, so that the two projectors are spliced into a fusion display.
It should be noted, however, that at least one of the positions/sequences of the ultra-wide multimedia source picture where the picture block is located can be recorded during cutting of the cut picture blocks, so that the picture blocks are marked, and the projector can debug the picture blocks in the corresponding positions according to the projection area set by the projector, so that the picture blocks can be conveniently spliced into a fusion display.
In the preferred embodiment, the mark of each drawing block may be a visual label printed on the screen, such as the drawing block a shown in fig. 1 and the drawing block B shown in fig. 1, for manual or software automatic identification and projection of the corresponding position to form a fusion display.
(II)
In addition, in another preferred embodiment, in order to further facilitate the fusion of the images for linking, in this embodiment, the method for fusion and display of ultra-wide images includes the steps of: cutting the ultra-wide multimedia source into a plurality of picture blocks; and in the multimedia interface display size range, taking the width value of the resolution of the ultra-wide multimedia source as a picture block cutting width value; the cutting length value of the single block of the picture is smaller than the length value of the display size range of the multimedia interface; sequentially layering the drawing blocks to recombine into an output drawing source which accords with the display size range of the multimedia interface; and each display device acquires an output picture source, respectively displays the picture block areas corresponding to the display devices in the output picture source in a PIP (picture in picture) mode, and splices the picture block areas into a fusion display.
It should be noted that, because the supported display size range of the projector is very wide according to different performance, but the scheme of the present invention can be appropriately adjusted according to the display size range of the projector, as shown in fig. 2, this embodiment is described by taking 4 projectors 11, 12, 13, 14 with a resolution of 1920 × 1080 as an example, in order to solve the problem of joining of the merged picture and facilitate the projection and layout of the device in the picture merging area, where the picture block may be set to different picture block types during the splitting, for example, including: the direct display block and the fusion block are because when the projector displays each layer of block area on the output source, a part of the block area close to the boundary of the output source is inevitably exposed to the interruption/missing display, and if a projector is specially arranged for the small block area, the projector is not wasted too much and uneconomical, so that a fusion block needs to be set to copy the block arranged at the boundary of the output source and is arranged again in the next layer, so that another projector can be connected to perform the fusion display.
Specifically, as shown in fig. 2, when the ultra-wide multimedia source has a resolution of 5760x1080, the width value, i.e. 1080 size, of the ultra-wide multimedia source may be used as the cutting width value of the block, and meanwhile, according to the size of the ultra-wide multimedia source, within the HDMI display range, two layers of blocks may be set and projected by the 4 projectors, and the cutting length value of the block is adjusted according to the maximum support size of the currently adapted multimedia interface, and meanwhile, the display size range of the projector may also be considered, for example, in the present HDMI interface, the single cutting length value of the block needs to be smaller than 3840, and the length value may also be allocated according to the number of the display devices, for example, in the present embodiment, it is preferable that the length value of the direct display block is the same as the length value of the fusion block, so that 3 blocks of blocks are cut into x1080, and copies the B tile and combines the two layers in the stack as in fig. 2, so that 2880 × 2160 output picture source can be obtained for full display in the resolution range supported by the HDMI interface.
Thus, as shown in fig. 2, the projector 12 and the projector 13 select different picture areas by the PIP method to simultaneously show part of the B picture blocks and perform fusion display, thereby avoiding missing display, and simultaneously facilitating adjustment in actual use, thereby saving the number of projectors and forming the maximum utilization efficiency.
(III)
In another embodiment, if the ultra-wide multimedia source has a resolution of 6720X1080 and the projector has a resolution of 960X1080, the length of the direct-display block is preferably a multiple of the length of the fusion block, so as to be divided and recombined into an output image source conforming to the display range of the HDMI interface, as shown in fig. 3, the ultra-wide multimedia source is preferably divided into 3 blocks of two sizes, namely a direct-display block a, a direct-display block C2880X 1080 and a fusion block B960X 1080, and the B and C image blocks are copied and connected to recombine the two layers of the stack, so that the output image source of 3840X2160 can be obtained to be displayed in the resolution range supported by the HDMI interface, and the corresponding image block areas in the output image source are respectively displayed in a PIP mode of the display device to be spliced into a fusion display.
(IV)
In another embodiment, if the ultra-wide multimedia source is 8960X720 resolution, and the projector resolution is 1280X720, the length of the direct display block is preferably greater than or equal to 1 time of the length of the fused block, so as to be divided and recombined into an output image source conforming to the HDMI display range, as shown in fig. 4, the ultra-wide multimedia source is preferably divided into 5 blocks of two sizes, i.e., a direct display block a, an E2560X 720, a C1280X 720 and a fused block B, and a D1280X 720, and simultaneously copies the two blocks B, D and a, C, and E, to be joined to recombine into three layers, so as to obtain an output image source of 3840X2160, to be displayed in the resolution range supported by the HDMI interface, and to respectively show the corresponding image blocks in the output image source by the PIP mode of the display device, and to be spliced into the fused display.
In addition, in the embodiments of the present invention, when the showing device shows the fused picture block, the edge feathering is performed on the fused band of the fused picture block. Also in various embodiments of the present invention, the ultra-wide multimedia source preferably comprises: at least one of a video source or a pattern source.
It should be noted, however, that at least one of the positions/sequences of the ultra-wide multimedia source picture where the picture block is located can be recorded during cutting of the cut picture blocks, so that the picture blocks are marked, and the projector can debug the picture blocks in the corresponding positions according to the projection area set by the projector, so that the picture blocks can be conveniently spliced into a fusion display.
In a preferred embodiment, the mark of each picture block may be a visual label printed on the picture, as shown in fig. 2 a, B, C and fig. 3 a, B, C, D, E, for manual or software automatic identification and projection of the corresponding position to form a fusion display, and in this embodiment, after the mark is printed on the screen of the display area by a projector, the display picture blocks are spliced and adjusted by manual visualization, so that the manual fusion of the picture and adjustment can be facilitated, and the problem of inserting a wrong picture block can be avoided.
(V)
In addition, the invention also provides an ultra-wide picture fusion display system, which comprises: the multimedia source processing device processes the ultra-wide multimedia source according to the ultra-wide multimedia source fusion display method to obtain output picture sources, each display device is in networking communication with the multimedia source processing device, the display devices are sequentially arranged in display areas according to the picture block cutting sequence, the display devices display the corresponding picture block areas in the output picture sources in a PIP mode and are spliced into fusion display in the display areas, and in the preferred embodiment, when the display devices display the fusion picture blocks, the multimedia source processing device performs edge feather processing on fusion bands of the fusion picture blocks.
