After the processing unit 21 receives the original image data (such as the original two-dimensional image data or the original three-dimensional image data) from the endoscope system 3, it can provide image frames, and determine whether the original image data is original 3D image data according to the image frames. For example, Fig. 2 provides examples of effective display areas of various image data of the endoscope system 3, the effective display area of the image data provided by the endoscope system 3 may not be rectangular, and there may be various types of image data in these image data For effective display areas of different shapes (for example: trapezoid, parallelogram, pentagon, hexagon, circle, etc.), the processing unit 21 can determine the original two-dimensional display area according to the display range of the image display area in the original image data. In the image data, or the original 3D image data, whether the effective display area of the image data is a rectangle, if it is judged to be no, then a rectangular display area can be formed along the outer tangent according to the shape of the image display area, and the coordinates The plane is divided into a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant. In one of the embodiments, the processing unit 21 may divide the coordinate plane into a first quadrant, a second quadrant, a third quadrant, and the fourth quadrant. For example, the processing unit 21 can, for example, define the image center point C0 as the origin (0,0) of the X-Y coordinate plane corresponding to the shape of the image display area, and take the maximum and minimum values corresponding to the X-axis and Y-axis in the effective display range, respectively. When the display area in the original image data is not a rectangle, the processing unit 21 can correct the shape of the display area to be a rectangle, and provide the image data with a rectangular display area as an image frame. For example, when the effective display area is a circle with a radius of 50 pixels, the maximum and minimum point coordinates of the effective display area corresponding to the X-axis and Y-axis are (0,50), (50,0), (-50, 0), and (0,-50), in this case, the processing unit 21 can correct the shape of the display area to be a rectangle, and the four vertices of the corrected rectangle are (50,50), (-50, 50), (-50,-50), and (50,-50), whereby image frames are provided according to the image display area in the original 2D image data or the original 3D image data.

After obtaining the image frame, the processing unit 21 can analyze a single image frame (that is, a frame in the image data), and judge whether the original image data is the original three-dimensional image data according to the image frame, if the judgment result is If not, determine that the original image data is the original two-dimensional image data, and generate an image mask corresponding to the original two-dimensional image data in the image frame according to the center of gravity coordinates of multiple triangles in the coordinate plane, and generate the second image mask according to the image mask A three-dimensional image data. Please refer to Figure 3. In Figure 3, C0 refers to the center point of the image (such as the centroid of a rectangle), which is also the origin of the X-Y coordinate plane; o1, p1, q1, a, b, and c refer to the triangle The vertex coordinates of ; G0, G1, G2, G3, and G4 refer to the coordinates of the center of gravity of the triangle corresponding to different triangles; G0' refers to the coordinates obtained after adding G0 to the parallax correction value. Here, in order to be able to express more clearly The point coordinates of G0 and G0' are represented by boxes in the direction relation. For example, in a single image frame, the image center point C0 (that is, the centroid C0) of the image frame can be defined as the origin (0,0) of the X-Y coordinate plane, thereby dividing the X-Y coordinate plane into The first quadrant, the second quadrant, the third quadrant, and the fourth quadrant, and then take any point a in the image boundary of the image frame, and connect it with the opposite vertices b and c to form a triangle abc, and then take three pieces of the triangle abc The median line and get the intersection point G0, which is the center of gravity G0 of the triangle abc. Next, similarly, in the first quadrant, the second quadrant, the third quadrant, and the fourth quadrant, the center-of-gravity coordinates G1 , G2 , G3 , and G4 of a plurality of triangles are obtained respectively. Then, taking the center of gravity G0 of the triangle abc as an example, the parallax correction value (ΔX, ΔY) can be added to the center of gravity G0 to obtain the parallax correction coordinate G0'. For example, suppose the coordinates of the center of gravity G0 are G0 (0,-100), The parallax correction value is (Δ5, Δ5), and the parallax correction coordinate G0' is (0±5,-100±5), that is, G0'(-5,-105), G0'(5,-105), G0 '(-5,-95), and G0'(5,-95), and add the parallax correction value (ΔX, ΔY) to the center of gravity G1, G2, G3, and G4 in a similar way to obtain the parallax correction Coordinates G1', G2', G3', and G4'. After obtaining the coordinates of the center of gravity of the triangle (G1, G2, G3, G4) and parallax correction coordinates (G1', G2', G3', G4'), the pixel values corresponding to these coordinates can be obtained respectively. The status (pattern, such as: H band, or V band, etc.) can be extended to multi-pixel values in the X-axis direction or Y-axis direction according to the situation, and a pixel value sum judgment formula is executed. For example, when the judgment formula ΣG1=ΣG2', or ΣG1=ΣG4', or ΣG0=ΣG0', and ΣG1≠ΣG2'≠ΣG4'≠ΣG0' is not established, it is judged according to the image frame whether the original image data is the original three-dimensional If the judgment result of the image data is negative, it is determined that the original image data provided by the endoscope system 3 is a two-dimensional image data, and an image mask corresponding to the original two-dimensional image data is generated according to the center of gravity coordinates of a plurality of triangles, and according to the image The mask generates the first three-dimensional image data including the image mask; when the above-mentioned judgment formula is established, the judgment result of judging whether the original image data is the original three-dimensional image data according to the image frame is yes, and it is judged that the endoscope system 3 provides The original image data is 3D image data, and the data format of the original 3D image data is further determined according to the pixel values of the center of gravity coordinates of the triangles, and the first 3D image data including the data format is generated according to the data format.

Next, please refer to FIG. 4 . The processing unit 21 can determine the data format of the original 3D image data according to the pixel values of the center of gravity coordinates of multiple triangles in the coordinate plane in a single image frame. First, similarly, the image center point C0 of the image frame can be defined as the origin of the X-Y coordinate plane, thereby dividing the X-Y coordinate plane into the first quadrant, the second quadrant, the third quadrant, and the fourth quadrant, and then , divide the first quadrant, the second quadrant, the third quadrant, and the fourth quadrant into a plurality of regions to form a plurality of triangle vertex coordinates, and these regions are used to obtain pixels corresponding to the barycenter coordinates of a plurality of triangles value. For example, the X-Y coordinate plane can be divided into 2M*2N areas according to the first quadrant, the second quadrant, the third quadrant, and the fourth quadrant, and the barycentric coordinates of 2M*2N triangles corresponding to these areas can be obtained (such as J, J', J''), and the offset coordinates of the center of gravity (such as K, the offset coordinate K of the center of gravity corresponds to the coordinate J of the center of gravity, and the coordinate of the offset coordinate K of the center of gravity is the coordinate of the next pixel from the coordinate J of the center of gravity ( That is, the negative direction of the Y axis), and the center of gravity coordinates J, J', J'' of each triangle have corresponding center of gravity offset coordinates K, K', K'', in the figure only the center of gravity coordinates J, and The barycenter offset coordinate K is taken as an example), and obtain each barycenter coordinate and the pixel value of the barycenter offset coordinate. After obtaining the pixel values of the center of gravity coordinates and the center of gravity offset coordinates, a pixel value operation can be performed on these pixel values to determine the data format of the original 3D image data. For example, assuming that the sum of the pixel values corresponding to the center of gravity coordinates in the first quadrant is J1, the sum of the pixel values corresponding to the center of gravity offset coordinates is K1, and the sum of the pixel values corresponding to the center of gravity coordinates in the second quadrant is J2, The sum of the pixel values corresponding to the center of gravity offset coordinates is K2, the sum of the pixel values corresponding to the center of gravity coordinates in the third quadrant is J3, the sum of the pixel values corresponding to the center of gravity offset coordinates is K3, and the fourth quadrant corresponds to the center of gravity The sum of the pixel values of the coordinates is J4, and the sum of the pixel values corresponding to the offset coordinates of the center of gravity is K4; when the operation formula: ∣(J1+J2)-(J3+J4) ∣, the operation result is equal to 0, or equal to the parallax adjustment value T , it can be judged that the data format of the 3D image data is Top & Bottom, where the parallax adjustment value T can be set by the user according to the situation; when the calculation formula: |(J1+J4)-(J2+J3)| When the absolute value is equal to 0, or equal to the parallax adjustment value T', it can be judged that the data format of the 3D image data is Side by Side, wherein the parallax adjustment value T' can be set by the user according to the situation; when the calculation formula: |(J1 +J2+J3+J4)-(K1+K2+K3+K4)｜When the absolute value of the operation result is equal to 0, or equal to the parallax adjustment value T'', it can be judged that the data format of the 3D image data is Line by Line, Wherein, the parallax adjustment value T'' can be set by the user according to the situation. After the determination of the data format of the original 3D image data is completed, the user can confirm the parallax of the 3D image. If the data format is incorrect, another image frame can be taken and the above process repeated. In this embodiment, the first 3D image data includes the data format. By generating the first 3D image data including the data format, complicated specification settings can be avoided, so that the first 3D image data can be quickly and easily displayed by the 3D display device. 5, and the external device 4 utilizes.
