[0002] Currently, the image resolution outputted by the three-dimensional (3D) surgery image generation device is only supported to full high definition (FHD), and the manufacturers of image signal scaling integrated circuits (Scaler ICs) also do not provide ultra high definition (UHD) support. If a frame buffer is used as a memory to scale the three-dimensional surgery image, there is a risk of surgery delay.

[0003] In addition, the resolution of the current display panel is UHD or higher. How to avoid three-dimensional (3D) image fragmentation, improve the high definition / full high definition three-dimensional surgery image to be outputted to a 4k UHD panel, reduce the hardware circuit cost of multiple image signal Scaler ICs and field programmable logic gate array (FPGA) support due to different image formats, and reduce the surgery risk caused by picture delay due to multiple integrated circuits is an important issue to be solved in the field.

Only a single Scaler IC and FPGA are needed to scale and arrange the three-dimensional image, which can avoid image fragmentation, reduce the risk of surgery delay, and improve the output to a 4k UHD panel, where 4k UHD represents a horizontal resolution of the panel reaching a level of more than four thousand pixels.

[0005] The three-dimensional data format conversion method provided by the present application is suitable for a polarized three-dimensional display system, wherein the polarized three-dimensional display system is used to output a three-dimensional image having a display image format and a display image resolution.

The signal scaling module is used to scale the three-dimensional image. The image arrangement module is connected to the signal scaling module and is used to arrange the three-dimensional image. The control module is connected to and controls the signal scaling module and the image arrangement module, and is used to perform a three-dimensional data format conversion method of the three-dimensional image. The control module acquires a first image resolution of a first three-dimensional image to determine whether the first image resolution is not the display image resolution. When the first image resolution is not the display image resolution, the signal scaling module is controlled to scale the pixel images of the first three-dimensional image to become a second three-dimensional image having a second image resolution, and the image arrangement module is controlled to arrange the pixel images of the second three-dimensional image to become a third three-dimensional image having the display image resolution and the display image format. The display image format is a row interlaced arrangement format.

[0010] In an embodiment of the present application, the control module determines that the first image resolution is the display image resolution and the first image format is the display image format, and outputs the first three-dimensional image. When the control module determines that the first image resolution is the display image resolution and determines that the first image format is not the display image format, the pixel images of the first three-dimensional image are arranged to become a fourth three-dimensional image having the display image resolution and the display image format.

[0011] In an embodiment of the present application, when the first image format is the row interlaced arrangement format, each pixel image of the first three-dimensional image is copied adjacent in the row direction, and each odd and even row pixel image after the adjacent copying is interlaced copied in the column direction to arrange the third three-dimensional image.

[0013] In an embodiment of the present application, when the first image format is the left-right arrangement format, each pixel image of the left image and the right image of the first three-dimensional image is adjacent copied in the row direction and adjacent copied in the column direction, and each row of pixel images of the adjacent copied left image and each row of pixel images of the adjacent copied right image are adjacent interleaved in the column direction to arrange the third three-dimensional image.

[0014] In an embodiment of the present application, the first three-dimensional image is divided into the left image and the right image.

[0015] In an embodiment of the present application, when the first image format is the left-right arrangement format, each pixel image of the even rows of the left image and each pixel image of the odd rows of the right image of the first three-dimensional image is adjacent copied in the row direction, and each row of pixel images of the adjacent copied left image and each row of pixel images of the adjacent copied right image are adjacent interleaved in the column direction to arrange the third three-dimensional image.

[0036] Please refer to Figure 1Fig. 1 shows a schematic diagram of a polarization type three-dimensional display system according to an embodiment of the present application. The polarization type three-dimensional display system 1 according to the present application comprises a signal scaling module 2, an image arrangement module 3, and a control module 4. The image arrangement module 3 is connected to the signal scaling module 2, and the control module 4 is connected to the signal scaling module 2 and the image arrangement module 3. In addition, the polarization type three-dimensional display system 1 according to the present application is used to output a three-dimensional image having a display image format and a display image resolution. The signal scaling module 2 is used to scale the three-dimensional image, the image arrangement module 3 is used to arrange the three-dimensional image, and the control module 4 is used to perform a three-dimensional data format conversion method of the three-dimensional image. It should be noted that the display image format has, for example, a line by line format, a side by side format, and a top and bottom format, and the display image resolution has, for example, a high definition (HD), a full high definition (FHD), a 4k ultra high definition (4k UHD), and an 8k ultra high definition (8k UHD). In the present embodiment, the three-dimensional image output by the polarization type three-dimensional display system 1 is viewed by a user wearing a polarization type glasses. Therefore, the polarization type three-dimensional display system 1 outputting a three-dimensional image having a display image format such as a line by line format and a display image resolution such as a 4k ultra high definition is taken as an example.

[0037] Referring to Fig. 1, the polarization type three-dimensional display system 1 according to the present application comprises the signal scaling module 2, the image arrangement module 3, and the control module 4. Figure 2 Fig. 2 shows a flowchart of a three-dimensional data format conversion method according to an embodiment of the present application. The three-dimensional data format conversion method according to the present application comprises the following steps.

[0038] Step S3: The control module 4 determines whether the input image resolution of the input three-dimensional image is the display image resolution of the three-dimensional image output by the polarization type three-dimensional display system 1. When the determination is no, the process proceeds to step S5. When the determination is yes, the process proceeds to step S9.

[0039] Step S5: When the control module 4 determines that the input image resolution of the input three-dimensional image is not the display image resolution of the three-dimensional image output by the polarization type three-dimensional display system 1, the control module 4 controls the signal scaling module 2 to scale the pixel image of the input three-dimensional image to become a scaled three-dimensional image having a scaled image resolution.

[0040] Step S7: The control module 4 controls the image arrangement module 3 to arrange the pixel image of the scaled three-dimensional image to become an output three-dimensional image having the same display image resolution and display image format as the polarization type three-dimensional display system 1.

[0041] Step S9: When the control module 4 determines that the input image resolution of the input three-dimensional image is the same as the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1, the control module 4 determines whether the input image format of the input three-dimensional image is the same as the display image format of the three-dimensional image output by the polarized three-dimensional display system 1.

[0042] Step S11: When the control module 4 determines that the input image format of the input three-dimensional image is not the display image format of the three-dimensional image output by the polarized three-dimensional display system 1, the control module 4 controls the image arrangement module 3 to arrange the pixel image of the input three-dimensional image to become an output three-dimensional image with the same display image resolution and display image format as the three-dimensional image output by the polarized three-dimensional display system 1.

[0043] Please refer to Figure 3 The diagram shown is a schematic of the scaling and arrangement of three-dimensional images provided in the first embodiment of the present invention. When the control module 4 determines that the input image format of the input three-dimensional image is the row-interlaced arrangement format output by the polarized three-dimensional display system 1, the control module 4 controls the scaling module 2 to copy each pixel image of the input three-dimensional image adjacently in the row direction, and the control module 4 controls the image arrangement module 3 to copy each odd-numbered row and even-numbered row pixel image after the above adjacent copying in the column direction to arrange them into an output three-dimensional image.

[0044] Please refer to Figure 4 The diagram shown is a schematic of the scaling and arrangement of three-dimensional images provided in the second embodiment of the present invention. When the control module 4 determines that the input image format of the input three-dimensional image is the row-interlaced arrangement format output by the polarized three-dimensional display system 1, the control module 4 controls the scaling module 2 to copy each row of pixels of the input three-dimensional image adjacently in the row direction, and each row of pixels of the input three-dimensional image copied adjacently in the row direction is copied adjacently in the column direction. The control module 4 controls the image arrangement module 3 to swap the odd-numbered row pixels of the adjacently copied even-numbered rows with the adjacent even-numbered row pixels of the odd-numbered rows to arrange them into an output three-dimensional image. In another embodiment, when the control module 4 determines that the input image format of the input three-dimensional image is the row-interlaced arrangement format output by the polarized three-dimensional display system 1, the control module 4 controls the scaling module 2 to copy each pixel image of the input three-dimensional image adjacently in a square matrix manner, and the control module 4 controls the image arrangement module 3 to swap the adjacent copied odd-row pixel images located in even-numbered rows with the adjacent even-row pixel images located in odd-numbered rows to arrange them into an output three-dimensional image.

[0045] Please refer to Figure 5Fig. 1 shows a schematic diagram of the three-dimensional data format conversion provided by an embodiment of the present application. For example, the input image format of the input three-dimensional image is a row interlaced arrangement format, and the input image resolution of the input three-dimensional image is ultra-high definition, such as 2160*3840. When the control module 4 judges that the input image format of the input three-dimensional image and the display image format of the three-dimensional image output by the polarized three-dimensional display system 1 are the same, and the input image resolution of the input three-dimensional image and the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1 are the same, then the signal scaling module 2 and the image arrangement module 3 do not scale and arrange the input three-dimensional image, but let the input three-dimensional image be directly output as the output three-dimensional image.

[0046] Please refer to Figure 6 Fig. 1 shows a schematic diagram of the three-dimensional data format conversion provided by an embodiment of the present application. For example, the input image format of the input three-dimensional image is a row interlaced arrangement format, and the input image resolution of the input three-dimensional image is ultra-high definition, such as 2160*3840. When the control module 4 judges that the input image format of the input three-dimensional image and the display image format of the three-dimensional image output by the polarized three-dimensional display system 1 are the same, and the input image resolution of the input three-dimensional image and the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1 are the same, then the signal scaling module 2 and the image arrangement module 3 do not scale and arrange the input three-dimensional image, but let the input three-dimensional image be directly output as the output three-dimensional image.

[0047] Please refer to Figure 7As shown in FIG. 1, it is a schematic diagram of the three-dimensional data format conversion provided by the embodiment of the present application. For example, the input image format of the input three-dimensional image is the row interlaced arrangement format, and the input image resolution is high definition such as 720*960. When the control module 4 judges that the input image format of the input three-dimensional image is the same as the display image format of the three-dimensional image output by the polarized three-dimensional display system 1, but the input image resolution of the input three-dimensional image is different from the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1 and is high definition, the signal scaling module 2 copies each row of pixel images of the input three-dimensional image in the row direction (such as the input three-dimensional image resolution becomes 720*3840) and copies each row of pixel images of the input three-dimensional image after the row direction adjacent copying in the column direction (such as the input three-dimensional image resolution becomes 2160*3840), and then the image arrangement module 3 arranges each row of pixel images of the input three-dimensional image after the adjacent copying into the output three-dimensional image (such as the output three-dimensional image resolution becomes 2160*3840). In addition, in another embodiment, when the control module 4 judges that the input image format of the input three-dimensional image is the same as the display image format of the three-dimensional image output by the polarized three-dimensional display system 1, but the input image resolution of the input three-dimensional image is different from the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1 and is high definition, the signal scaling module 2 copies each pixel image of the input three-dimensional image in the square matrix manner (such as the input three-dimensional image resolution becomes 2160*3840), and the control module 4 controls the image arrangement module 3 to arrange the odd row pixel images of the even rows after the above adjacent copying and the even row pixel images of the adjacent odd rows to form the output three-dimensional image.

[0048] Please refer to Figure 8 As shown in FIG. 1, it is a schematic diagram of the three-dimensional data format conversion provided by the embodiment of the present application. For example, the input image format of the input three-dimensional image is the row interlaced arrangement format, and the input image resolution is high definition such as 720*960. When the control module 4 judges that the input image format of the input three-dimensional image is the same as the display image format of the three-dimensional image output by the polarized three-dimensional display system 1, but the input image resolution of the input three-dimensional image is different from the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1 and is high definition, the signal scaling module 2 copies each row of pixel images of the input three-dimensional image in the row direction (such as the input three-dimensional image resolution becomes 720*3840) and copies each row of pixel images of the input three-dimensional image after the row direction adjacent copying in the column direction (such as the input three-dimensional image resolution becomes 2160*3840), and then the image arrangement module 3 arranges each row of pixel images of the input three-dimensional image after the adjacent copying into the output three-dimensional image (such as the output three-dimensional image resolution becomes 2160*3840). In addition, in another embodiment, when the control module 4 judges that the input image format of the input three-dimensional image is the same as the display image format of the three-dimensional image output by the polarized three-dimensional display system 1, but the input image resolution of the input three-dimensional image is different from the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1 and is high definition, the signal scaling module 2 copies each pixel image of the input three-dimensional image in the square matrix manner (such as the input three-dimensional image resolution becomes 2160*3840), and the control module 4 controls the image arrangement module 3 to arrange the odd row pixel images of the even rows after the above adjacent copying and the even row pixel images of the adjacent odd rows to form the output three-dimensional image. Figure 8As shown, for example, to convert a full high-definition input three-dimensional image with a resolution of 1080*1920 into a 4K output three-dimensional image with a resolution of 2160*3840, the signal scaling module 2 can expand the row resolution (including the left image and the right image) from 1920 to 7680 by copying each pixel image of the left image and the right image of the input three-dimensional image adjacent in the row direction, and then arrange the expanded left image and the right image adjacent in the column direction to form the 4K output three-dimensional image with a resolution of 2160*3840. In another embodiment, when the control module 4 determines that the input image format of the input three-dimensional image is the left-right arrangement format, the control module 4 controls the signal scaling module 2 to copy each pixel image of the left image and the right image of the input three-dimensional image adjacent in a square manner, and the control module 4 controls the image arrangement module 3 to arrange each row of pixel images of the left image adjacent in the row direction and each row of pixel images of the right image adjacent in the row direction adjacent in the column direction to form the output three-dimensional image.

[0049] Please refer to Figure 9 As shown, for example, to convert a full high-definition input three-dimensional image with a resolution of 1080*1920 into a 4K output three-dimensional image with a resolution of 2160*3840, the signal scaling module 2 can expand the row resolution (including the left image and the right image) from 1920 to 7680 by copying each pixel image of the left image and the right image of the input three-dimensional image adjacent in the row direction, and then arrange the expanded left image and the right image adjacent in the column direction to form the 4K output three-dimensional image with a resolution of 2160*3840. In another embodiment, when the control module 4 determines that the input image format of the input three-dimensional image is the left-right arrangement format, the control module 4 controls the signal scaling module 2 to copy each pixel image of the left image and the right image of the input three-dimensional image adjacent in a square manner, and the control module 4 controls the image arrangement module 3 to arrange each row of pixel images of the left image adjacent in the row direction and each row of pixel images of the right image adjacent in the row direction adjacent in the column direction to form the output three-dimensional image.

[0050] Please refer to Figure 10 As shown, for example, to convert a full high-definition input three-dimensional image with a resolution of 1080*1920 into a 4K output three-dimensional image with a resolution of 2160*3840, the signal scaling module 2 can expand the row resolution (including the left image and the right image) from 1920 to 7680 by copying each pixel image of the left image and the right image of the input three-dimensional image adjacent in the row direction, and then arrange the expanded left image and the right image adjacent in the column direction to form the 4K output three-dimensional image with a resolution of 2160*3840. In another embodiment, when the control module 4 determines that the input image format of the input three-dimensional image is the left-right arrangement format, the control module 4 controls the signal scaling module 2 to copy each pixel image of the left image and the right image of the input three-dimensional image adjacent in a square manner, and the control module 4 controls the image arrangement module 3 to arrange each row of pixel images of the left image adjacent in the row direction and each row of pixel images of the right image adjacent in the row direction adjacent in the column direction to form the output three-dimensional image.

[0051] Please refer to Figure 11Fig. 1 shows a schematic diagram of the three-dimensional data format conversion provided by an embodiment of the present application. For example, the input image format of the input three-dimensional image is the left-right arrangement format, and the input image resolution is the ultra-high definition, such as 2160*3840. When the control module 4 judges that the input image resolution of the input three-dimensional image is the same as the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1, but judges that the input image format of the input three-dimensional image is different from the display image format of the three-dimensional image output by the polarized three-dimensional display system 1 and is the left-right arrangement format, then the signal scaling module 2 copies each pixel image of the even rows of the left image and each pixel image of the odd rows of the right image of the input three-dimensional image in the row direction (for example, the input three-dimensional image resolution becomes 2160*7680, the left image resolution becomes 2160*3840, and the right image resolution becomes 2160*3840), and the image arrangement module 3 arranges the even row pixel images of the left image and the odd row pixel images of the right image in the column direction to arrange the output three-dimensional image (for example, the output three-dimensional image resolution becomes 2160*3840).

[0052] Please refer to Figure 12 Fig. 1 shows a schematic diagram of the three-dimensional data format conversion provided by an embodiment of the present application. For example, the input image format of the input three-dimensional image is the left-right arrangement format, and the input image resolution is the ultra-high definition, such as 2160*3840. When the control module 4 judges that the input image resolution of the input three-dimensional image is the same as the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1, but judges that the input image format of the input three-dimensional image is different from the display image format of the three-dimensional image output by the polarized three-dimensional display system 1 and is the left-right arrangement format, then the signal scaling module 2 copies each pixel image of the even rows of the left image and each pixel image of the odd rows of the right image of the input three-dimensional image in the row direction (for example, the input three-dimensional image resolution becomes 2160*7680, the left image resolution becomes 2160*3840, and the right image resolution becomes 2160*3840), and the image arrangement module 3 arranges the even row pixel images of the left image and the odd row pixel images of the right image in the column direction to arrange the output three-dimensional image (for example, the output three-dimensional image resolution becomes 2160*3840).

[0053] Please refer to Figure 13Fig. 1 shows a schematic diagram of the three-dimensional data format conversion provided by an embodiment of the present application. For example, the input image format of the input three-dimensional image is the left-right arrangement format, and the input image resolution of the input three-dimensional image is high definition, such as 800*1600 (e.g., the left image resolution becomes 800*800, and the right image resolution becomes 800*800). When the control module 4 judges that the input image format and the input image resolution of the input three-dimensional image are different from the display image format and the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1, and are respectively high definition, left-right arrangement format, and resolution that is not an integer multiple of each other, the signal scaling module 2 makes the input three-dimensional image resolution become 960*1920 (e.g., the left image resolution becomes 960*960, and the right image resolution becomes 960*960) in a manner of copying part of the pixels or equal proportion scaling, and then makes each pixel image of the left image and the right image of the input three-dimensional image adjacent to each other in a square matrix manner (e.g., the input three-dimensional image resolution becomes 1920*3840, the left image resolution becomes 1920*1920, and the right image resolution becomes 1920*1920), and the image arrangement module 3 arranges the even-numbered row pixel images of the left image and the odd-numbered row pixel images of the right image adjacent to each other in the column direction to arrange the output three-dimensional image (e.g., the output three-dimensional image resolution becomes 1920*1920). However, it can be noted that the resolution of the output three-dimensional image is not ultra-high definition, and therefore the control module 4 makes the output three-dimensional image resolution become 2160*3840 in a manner of adding black pixels (e.g., the diagonal area) around the output three-dimensional image to conform to the output of ultra-high definition. In addition, the manner of copying part of the pixels is to make the input image resolution and the display image resolution present a multiple or equal proportion relationship on the basis of the image not being broken, for example, ten percent of the pixels of the input image are copied, twenty percent of the pixels are copied, or thirty percent of the pixels are copied, but the present application does not limit the manner of copying the pixels, the number of the copied pixels, and the area of the copied pixels.

[0054] Please refer to Figure 14 Fig. 6 shows a schematic diagram of the three-dimensional image scaling and arrangement provided by the sixth embodiment of the present application. When the control module 4 judges that the input image format of the input three-dimensional image is the up-down arrangement format, the control module 4 controls the signal scaling module 2 to make each pixel image of the upper image and the lower image of the input three-dimensional image adjacent to each other in a square matrix manner, and the control module 4 controls the image arrangement module 3 to arrange each row pixel image of the upper image adjacent to each other in the column direction after the square matrix adjacent copying and each row pixel image of the lower image adjacent to each other in the column direction after the square matrix adjacent copying to arrange the output three-dimensional image.

[0055] Please refer to Figure 15Fig. 1 shows a schematic diagram of the three-dimensional data format conversion provided by an embodiment of the present application. For example, the input image format of the input three-dimensional image is the up-down arrangement format, and the input image resolution is the ultra-high definition, such as 2160*3840. When the control module 4 judges that the input image resolution of the input three-dimensional image is the same as the display image resolution of the three-dimensional image output by the polarized three-dimensional display system 1, but judges that the input image format of the input three-dimensional image is not the same as the display image format of the three-dimensional image output by the polarized three-dimensional display system 1 and is the up-down arrangement format, the image arrangement module 3 arranges each row of pixel images of the upper image and each row of pixel images of the lower image in the column direction to arrange the output three-dimensional image.

[0056] Please refer to Figure 16 Fig. 2 shows a schematic diagram of the three-dimensional data format conversion provided by an embodiment of the present application. For example, the input image format of the input three-dimensional image is the up-down arrangement format, and the input image resolution is the full high definition, such as 1080*1920. When the control module 4 judges that the input image resolution and the input image format of the input three-dimensional image are not the same as the display image resolution and the display image format of the three-dimensional image output by the polarized three-dimensional display system 1 and are respectively the full high definition and the up-down arrangement format, the signal scaling module 2 copies each pixel image of the upper image and the lower image of the input three-dimensional image in the square matrix manner (for example, the input three-dimensional image resolution becomes 2160*3840, the upper image resolution becomes 1080*3840, and the lower image resolution becomes 1080*3840), and the image arrangement module 3 arranges each row of pixel images of the upper image and each row of pixel images of the lower image in the column direction to arrange the output three-dimensional image (for example, the output three-dimensional image resolution becomes 2160*3840).

[0057] Please refer to Figure 17 Fig. 3 shows a schematic diagram of the three-dimensional data format conversion provided by an embodiment of the present application. For example, the input image format of the input three-dimensional image is the up-down arrangement format, and the input image resolution is the high definition, such as 720*960. When the control module 4 judges that the input image resolution and the input image format of the input three-dimensional image are not the same as the display image resolution and the display image format of the three-dimensional image output by the polarized three-dimensional display system 1 and are respectively the high definition and the up-down arrangement format, the signal scaling module 2 copies each pixel image of the upper image and the lower image of the input three-dimensional image in the square matrix manner (for example, the input three-dimensional image resolution becomes 2160*3840, the upper image resolution becomes 1080*3840, and the lower image resolution becomes 1080*3840), and the image arrangement module 3 arranges each row of pixel images of the upper image and each row of pixel images of the lower image in the column direction to arrange the output three-dimensional image (for example, the output three-dimensional image resolution becomes 2160*3840).
