接著請參閱圖2，本發明的影像投射裝置D產生的第一投影光束P1與第二投影光束P2可沿著相同的方向移動且同步投射在一微鏡模組3上，以形成並列的多個掃描點31，其中每一個掃描點31就是一個畫素所涵蓋的區域。為了解釋方便，將微鏡模組3劃分成多行與多列，舉例來說，本案的微鏡模組3可在X方向上劃分n列，在Y方向上劃分n行(如圖2所示)，且每一個(X,Y)單位表示一個掃描點31。第一光源模組1以及第二光源模組2在單位時間內，分別通過投出單一的第一投影光束P1以及第二投影光束P2以形成兩個掃描點31。換句話說，每一個掃描點31一次僅接受一第一投影光束P1或一第二投影光束P2。除此之外，在本實施例中，影像投射裝置D的第一發光群組13所產生的第一投影光束P1，以及第二發光群組23所產生的第二投影光束P2，是同步地投射在Y方向的兩相鄰掃描點31(畫素所涵蓋的區域)上，並以X方向移動，使得微鏡模組3的兩相鄰X方向(橫列)逐步接受第一投影光束P1或第二投影光束P2，以形成兩橫列的多個掃描點31。 2, the first projection beam P1 and the second projection beam P2 generated by the image projection device D of the present invention can be moved in the same direction and simultaneously projected onto a micromirror module 3 to form a plurality of juxtapositions. Scan points 31, each of which is an area covered by a pixel. For convenience of explanation, the micromirror module 3 is divided into a plurality of rows and a plurality of columns. For example, the micromirror module 3 of the present invention can divide n columns in the X direction and divide n rows in the Y direction (as shown in FIG. 2). Shown, and each (X, Y) unit represents a scan point 31. The first light source module 1 and the second light source module 2 respectively form a single scanning point 31 by projecting a single first projection beam P1 and a second projection beam P2 per unit time. In other words, each scanning point 31 receives only one first projection beam P1 or a second projection beam P2 at a time. In addition, in this embodiment, the first projection beam P1 generated by the first illumination group 13 of the image projection device D and the second projection beam P2 generated by the second illumination group 23 are synchronously Projected in two adjacent scanning points 31 (areas covered by the pixels) in the Y direction, and moved in the X direction, so that the two adjacent X directions (rows) of the micromirror module 3 gradually receive the first projection beam P1 Or the second projection beam P2 to form a plurality of scan points 31 of two courses.
接著，當完成Y方向上的同一橫列的多個掃描點31的掃描之後，例如根據圖2，完成(X1,Y1)至(Xn,Y1)，以及(X1,Y2)至(Xn,Y2)的掃描之後，影像投射裝置D便沿著X方向移動至接續的兩橫列(在本實施例中，是Y3及Y4的橫列)，再次同步地投射在Y方向的兩相鄰掃描點31上，並以X方向逆向移動，完成次兩橫列的掃描。由於光束的速度遠遠超過人眼可辨識的每秒單位幀數，因此單一光束分別依序投射至微鏡模組3的時間差無法被人眼察覺。影像投射裝置D藉由第一光源模組1以及第二光源模組2的設置，並利用前述方式，於單位時間內同時提供第一投影光束P1以及第二 投影光束P2至微鏡模組3，並以X方向往復移動，在Y方向上逐漸完成微鏡模組3的掃描，最終可形成一完整的影像。 Next, after the scanning of the plurality of scanning points 31 of the same course in the Y direction is completed, for example, according to FIG. 2, (X 1 , Y 1 ) to (X n , Y 1 ), and (X 1 , Y 2 are completed). After the scanning to (X n , Y 2 ), the image projecting device D moves in the X direction to the next two courses (in the present embodiment, the course of Y 3 and Y 4 ), again synchronously It is projected on two adjacent scanning points 31 in the Y direction, and is reversely moved in the X direction to complete the scanning of the next two courses. Since the speed of the beam far exceeds the number of unit frames per second recognizable by the human eye, the time difference in which the single beams are sequentially projected to the micromirror module 3 cannot be perceived by the human eye. The image projection device D is provided by the first light source module 1 and the second light source module 2, and simultaneously supplies the first projection beam P1 and the second projection beam P2 to the micromirror module 3 in a unit time. And reciprocating in the X direction, gradually completing the scanning of the micromirror module 3 in the Y direction, and finally forming a complete image.
承上所述，根據本發明第一實施例，影像投射裝置D在Y方向上相鄰的兩橫列同步提供第一投影光束P1與第二投影光束P2，以形成多個掃描點31，單位時間內可完成兩橫列的投影掃描程序。如此一來，本發明的影像投射裝置可在單位時間內完成較大面積的微鏡模組3的掃描。相較於現有的單橫列掃描程序，本發明提供的影像投射裝置D是以雙橫列掃描，故可以在一預定時間內完成更高畫質或者更高畫素的影像投射。 As described above, according to the first embodiment of the present invention, the image projecting device D synchronously provides the first projection beam P1 and the second projection beam P2 in two adjacent rows in the Y direction to form a plurality of scanning points 31, A two-row projection scan program can be completed in time.

需注意的是，本實例提供的控制模組D與第一實施例提供的控制模組D的差別在於，本實施例的第一光源模組1包括至少兩個第一驅動單元11，且第二光源模組2亦包括至少兩個第二驅動單元21。至少兩個第一驅動單元11的每一個均分別電性連接於一第一發光群組13，且至少兩個第二驅動單元21的每一個亦分別電性連接至一第二發光群組23。 It should be noted that the difference between the control module D and the control module D provided in the first embodiment is that the first light source module 1 of the embodiment includes at least two first driving units 11 and The two light source modules 2 also include at least two second driving units 21. Each of the at least two first driving units 11 is electrically connected to a first lighting group 13 , and each of the at least two second driving units 21 is also electrically connected to a second lighting group 23 . .
詳言之，控制模組C所提供的第一影像信號S1是通過至少兩個第一驅動單元11而傳送到第一發光群組13，且第二影像信號S2是通過至少兩個第二驅動單元21而傳送到第二發光群組23。第一影像信號S1可以同時通過至少兩個第一驅動單元11，第二影像信號S2亦可同時通過至少兩個第二驅動單元21。在本實施例中，是以兩個第一驅動單元11以及兩個第二驅動單元21做為例示，如圖3及圖4所示。然而，本實施例對應的圖式僅為例示，並非對本發明的第一驅動單元11以及第二驅動單元21的數量加以限制。換句話說，本發明的影像投射裝置可包括兩個以上的第一驅動單元11以及第二驅動單元21，例如三個。 In detail, the first image signal S1 provided by the control module C is transmitted to the first lighting group 13 through the at least two first driving units 11, and the second image signal S2 is passed through at least two second driving units. The unit 21 is transferred to the second lighting group 23. The first image signal S1 can pass through at least two first driving units 11 at the same time, and the second image signal S2 can also pass through at least two second driving units 21 at the same time. In the present embodiment, the two first driving units 11 and the two second driving units 21 are taken as an example, as shown in FIGS. 3 and 4. However, the drawings corresponding to the present embodiment are merely examples, and the number of the first driving unit 11 and the second driving unit 21 of the present invention is not limited. In other words, the image projecting device of the present invention may include two or more first driving units 11 and second driving units 21, for example three.
再者，第一影像信號S1的其中一部分通過其中一個第一驅動單元11a而傳送到第一發光群組13，且第一影像信號S1的另外一部分是通過另外的第一驅動單元11b而傳送到第一發光群組13。同樣地，第二影像信號S2的其中一部分通過其中一第二驅動單元21a而傳送到第二發光群組23，且第二影像信號S2的另外一部分通過另外一第二驅動單元21b而傳送到第二發光群組23。 Furthermore, a part of the first image signal S1 is transmitted to the first light-emitting group 13 through one of the first driving units 11a, and another part of the first image signal S1 is transmitted to the other first driving unit 11b. The first lighting group 13. Similarly, a part of the second image signal S2 is transmitted to the second lighting group 23 through one of the second driving units 21a, and another part of the second image signal S2 is transmitted to the second driving unit 21b. Two illumination groups 23.
接著，第一發光群組13根據來自其中一個第一驅動單元11a的部分第一影像信號S1以及來自另一個第一驅動單元11b的另外一部分第一影像信號S1，產生第一投影光束P1。第二發光群組23是根據來自其中一個第二驅動單元21a的部分第二影像信號S2，以及來自另一個第二驅動單元21b的另外一部分第二影像信號S2，以產生第二投影光束P2。 Next, the first lighting group 13 generates a first projection light beam P1 based on a portion of the first image signal S1 from one of the first driving units 11a and another portion of the first image signal S1 from the other first driving unit 11b. The second lighting group 23 is based on a portion of the second image signal S2 from one of the second driving units 21a and another portion of the second image signal S2 from the other second driving unit 21b to generate a second projection beam P2.
本發明第二實施例的影像投射裝置所發出的第一投影光束P1與第二投影光束P2，與前述的第一實施例的第一投影光束P1與第二投影光束P2的移動路徑相同。詳細說明之，如圖4所示，為了解釋方便，微鏡模組3可被劃分成多行與多列。舉例來說，本案的微鏡模組3可在X方向上劃分n列，在Y方向上劃分n行(如圖4所示)。在本實施例中，影像投射裝置D的第一發光群組13所產生的第一投影光束P1，以及第二發光群組23所產生的第二投影光束P2，是同步地投射在Y方向的兩相鄰掃描點31上，並以X方向移動，使得兩相鄰的Y方向(橫列)上的每一個掃描點31逐步接受第一投影光束P1以及第二投影光束P2以完成整列的掃瞄。 The first projection beam P1 and the second projection beam P2 emitted by the image projecting device of the second embodiment of the present invention are the same as the moving paths of the first projection beam P1 and the second projection beam P2 of the first embodiment described above. In detail, as shown in FIG. 4, for convenience of explanation, the micromirror module 3 can be divided into a plurality of rows and a plurality of columns. For example, the micromirror module 3 of the present invention can divide n columns in the X direction and n rows in the Y direction (as shown in FIG. 4). In this embodiment, the first projection beam P1 generated by the first illumination group 13 of the image projection device D and the second projection beam P2 generated by the second illumination group 23 are synchronously projected in the Y direction. Two adjacent scanning points 31, and moving in the X direction, so that each scanning point 31 in two adjacent Y directions (horizontal) gradually receives the first projection beam P1 and the second projection beam P2 to complete the sweep of the entire column. aim.
與前述的第一實施例不同的是，由於第一光源模組1以及第二光源模組2均分別包括至少兩個第一驅動單元11以及至少兩個第二驅動單元12，如此一來，第一發光群組13可接受通過兩個第一驅動單元11而被區分成一部分與另一部分的第一影像信號S1。由於信號傳送速度相當快，藉由兩個獨立的第一驅動單元11a以及11b的設置，可使其中一個第一驅動單元11a與另一個第一驅動單元11b交互輪替地傳送第一影像信號S1至第一發光群組13。如此一來，若藉由調整單位時間內傳送至第一發光群組13的第一影像信號S1的次數，第一發光群組13就可以提高單位時間內所產生的第一投影光束P1的次數。同理可證，第二發光群組23亦接受通過兩個第二驅動單元21而被分成一部分與另一部分的第二影像信號S2。兩個獨立的第二驅動單元21a以及21b的設置，可使其中一個第二驅動單元21a與另一個第二驅動單元21b交互輪替地傳送第二影像信號S2至第二發光群組23。藉此，第二發光群組23就可以提高單位時間內所產生的第二投影光束P2的次數。 The difference between the first light source module 1 and the second light source module 2 includes at least two first driving units 11 and at least two second driving units 12, respectively. The first lighting group 13 can accept the first image signal S1 divided into a portion and another portion by the two first driving units 11. Since the signal transmission speed is relatively fast, one of the first driving units 11a and the other first driving unit 11b can alternately transmit the first image signal S1 by the arrangement of the two independent first driving units 11a and 11b. To the first lighting group 13. In this way, if the number of times of transmitting the first image signal S1 to the first light-emitting group 13 per unit time is adjusted, the first light-emitting group 13 can increase the number of times of the first projection light beam P1 generated per unit time. . Similarly, the second lighting group 23 also accepts the second image signal S2 divided into a portion and another portion by the two second driving units 21. The two independent second driving units 21a and 21b are arranged such that one of the second driving units 21a and the other second driving unit 21b alternately transmit the second image signal S2 to the second lighting group 23. Thereby, the second lighting group 23 can increase the number of times of the second projection light beam P2 generated per unit time.
回顧第一實施例，在單位時間內，每一個掃描點31是接受一個第一投影光束P1或是一個第二投影光束P2。然而，在本實施例中，由於第一光源模組1增加一個第一驅動單元11，第二光源 模組2增加一個第二驅動單元21，第一光源模組1以及第二光源模組2在單位時間內可分別提供兩個第一投影光束P1以及兩個第二投影光束P2至個別的單一畫素所涵蓋的區域。換句話說，每一個掃描點31一次是接受兩個第一投影光束P1或兩個第二投影光束P2。 Recalling the first embodiment, each scanning point 31 receives a first projection beam P1 or a second projection beam P2 per unit time. However, in the embodiment, the first light source module 1 adds a first driving unit 11, the second light source module 2 adds a second driving unit 21, the first light source module 1 and the second light source module 2 The two first projection beams P1 and the two second projection beams P2 may be respectively provided in a unit time to the area covered by the individual single pixels. In other words, each scanning point 31 receives two first projection beams P1 or two second projection beams P2 at a time.
接著進行掃描的方式如本發明第一實施例所述，第一投影光束P1與第二投影光束P2同步地投射在Y方向的兩相鄰行上，並以X方向移動，使得兩相鄰的X方向(橫列)上的每一個掃描點31逐步接受兩個第一投影光束P1或兩個第二投影光束P2。當完成X方向上的同一橫列的多個掃描點31的掃描之後，例如根據圖4，完成(X1,Y1)至(Xn,Y1)，以及(X1,Y2)至(Xn,Y2)掃描點31之後，影像投射裝置D便沿著Y方向移動至接續的兩橫列(在本實施例中，是Y3及Y4的橫列)，再次同步地投射在Y方向的兩相鄰橫列上，並以X方向逆向移動，完成次兩橫列的掃描。由於光束的速度遠遠超過人眼可辨識的每秒單位幀數，因此投影光束依序投射至微鏡模組3的時間差無法被人眼察覺。影像投射裝置D藉由第一光源模組1以及第二光源模組2的設置，並利用前述方式，於單位時間內同時提供第一投影光束P1以及第二投影光束P2至微鏡模組3，並以X方向往復移動，在Y方向上逐漸完成微鏡模組3的掃描，最終可形成一完整的影像。 The scanning is performed in the same manner as the first embodiment of the present invention. The first projection beam P1 is projected on two adjacent rows in the Y direction in synchronization with the second projection beam P2, and is moved in the X direction so that two adjacent ones are adjacent. Each of the scanning points 31 on the X direction (horizontal) gradually receives two first projection beams P1 or two second projection beams P2. After the scanning of the plurality of scanning points 31 of the same course in the X direction is completed, for example, according to FIG. 4, (X 1 , Y 1 ) to (X n , Y 1 ), and (X 1 , Y 2 ) are completed. (X n , Y 2 ) After the scanning point 31, the image projecting device D moves in the Y direction to the next two courses (in the present embodiment, the course of Y 3 and Y 4 ), and projects again in synchronization. On the two adjacent courses in the Y direction, and moving in the X direction, the scanning of the next two courses is completed. Since the speed of the beam far exceeds the number of unit frames per second recognizable by the human eye, the time difference in which the projection beam is sequentially projected to the micromirror module 3 cannot be perceived by the human eye. The image projection device D is provided by the first light source module 1 and the second light source module 2, and simultaneously supplies the first projection beam P1 and the second projection beam P2 to the micromirror module 3 in a unit time. And reciprocating in the X direction, gradually completing the scanning of the micromirror module 3 in the Y direction, and finally forming a complete image.
承上所述，根據本發明第二實施例，影像投射裝置D可在同一個Y方向上相鄰的兩行同步提供第一投影光束P1與第二投影光束P2，如此單位時間內可完成兩橫列的投影掃描程序。此外，微鏡模組3的每一個掃描點31可在單位面積以及單位時間內接受至少兩個第一投影光束P1或是第二投影光束P2。換句話說，X方向上的光束密集度會增加一倍以上。如此一來，本發明的影像投射裝置可在單位時間內完成較大面積的微鏡模組3的掃描。總結來說，本發明提供的影像投射裝置D是以雙橫列掃描，且每一畫素 所涵蓋的區域可接受兩個以上的投影光束，以形成並列的多個掃描點31。藉此，相較於現有的單橫列掃描程序，本發明的影像投射裝置在X方向以及Y方向都具有雙倍投影光束的密度，因而可完成較高畫質的影像投射，例如Full HD 1920×1080解析度的影像輸出裝置，因而大幅增加影像輸出的品質。 According to the second embodiment of the present invention, the image projecting device D can simultaneously provide the first projection beam P1 and the second projection beam P2 in two rows adjacent in the same Y direction, so that two units can be completed in one unit time. The projection scan program of the course. In addition, each of the scanning points 31 of the micromirror module 3 can receive at least two first projection beams P1 or a second projection beam P2 per unit area and unit time. In other words, the beam intensity in the X direction is more than doubled. In this way, the image projection apparatus of the present invention can complete the scanning of the micro-mirror module 3 of a large area in a unit time. In summary, the image projection device D provided by the present invention scans in a double course, and the area covered by each pixel can accept more than two projection beams to form a plurality of parallel scanning points 31. Thereby, the image projection device of the present invention has a double projection beam density in both the X direction and the Y direction compared to the conventional single course scanning program, thereby achieving higher image quality image projection, such as Full HD 1920. The image output device of ×1080 resolution greatly increases the quality of image output.
