[Embodiment] The optical system of the present invention integrates the optical system of the digital camera with the optical system of the projector, so that the integrated optical system has a camera function and a projection function. The detailed integration method can be referred to the following three specific implementation methods. For the first embodiment of the optical system of the present invention, please refer to the first A, the first B, and the first c. The optical system of the first embodiment of the present invention includes a beam generating module 1 and an image forming. The module 20 and an image capturing module 30, wherein the beam generating module 1 is used to provide an illumination beam required for projection; the image forming module 20 receives the illumination beam from the beam generating module 1〇, and The image capturing module 30 is formed by the display component 22 and the image capturing module is projected by the zooming lens 24 . The image capturing module 30 can share the zoom lens 24 with the image forming module 2 , and capture the zoom lens 24 . Light outside of the optical system i, and an image is formed by an imager 32. In the example of the actual thin example, the aperture generating module 10 includes a light source (not shown, but may be, for example, a laser light source), a lens 12, a dichroic mirror 14, a lens array 16, and a polarization converter (not shown). An optical member such as the mirror 18 and the reproducing lens 19, whereby unpolarized light from the light source can be converted into desired linearly polarized light (for example, S-polarized light), and the irradiation beam can be uniformly emitted. The image forming module 20 is reached. In the first embodiment, the display element 22 in the image forming module 20 is a LCOS 'Liquid Crystal on Silicon panel. Therefore, the image forming module 2 〇 also needs a 201234096 polarization polarization beam splitter 26 To provide linearly polarized light to the LCOS panel, the polarizing beam splitter 26 is located between the display element 22 and the zoom lens 24 for receiving linearly polarized light from the beam generating module 10.

In the first embodiment, the imager 32 of the image capturing module 30 is a CCD 'Charge-Coupled Device'. The imager 32 is vertically arranged with the display element 22 and is respectively disposed on the polarization beam splitter. In the vicinity of the two adjacent vertical sides of the 26, the polarizing beam splitter 26 can receive the light outside the optical system 1 captured by the zoom lens 24 and reflect the light to the imager 32 for the image capturing mode. The specific optical transmission path of the group 3 is: the light drawn by the zoom lens 24 (ie, the mixed light of the S polarized light and the p polarized light) enters the optical system 本 of the present invention, and the light (S polarized light) passes through the polarizing beam splitter 26 After reflection, the imager 32 is entered to form an image on the imager 32. 4, referring to the first mode of operation of the optical system 1 of the first embodiment of the present invention shown in FIG. 1A, in which the optical system i has an autofocus function, enabling the image forming module 2G to be simultaneously enabled. The film is taken from the module 3, and the execution order and the camera instruction are executed at the time of closing to obtain the most (four) projection effect. For example, the Dana image is projected onto the glory outside the optical system 1 via the image axis 2Q, and can be captured by the image capturing module, such as by capturing the projected image, and then transmitting through the image signal processor (not shown). Whether the projected image is clear or not, so that the optimal projection focal length is selected by the first projection of the 201234096 moving circuit (not _), the image forming module 20 can project the highest quality image. That is, in this mode of operation, the optical system 1 can be employed by a highly accurate projector. The second mode of operation of the optical system 1 of the first embodiment of the present invention shown in the first figure of the present invention is in which only the image forming module 2 in the optical system 1 is activated but not activated.
