Description of the Invention: [Technical Field] The present invention relates to the field of image capture and image projection, and particularly to a portable electronic device having image capture and image projection functions. [Prior Art] In recent years, with the advancement of microelectronic technology, portable electronic devices, especially palm-sized electronic devices, have become more advanced and more functional. For example, a portable electronic device can have functions such as call, global positioning, photography, web browsing, and/or multimedia playback. The portable electronic devices widely used in the 1J include mobile phones (M〇biie phones), personal digital assistants (PDAs, Personal Digital Assistants), digital cameras (Digital Cameras), laptop computers, etc. Take the function. However, due to their small size, the portable electronic devices have a large limitation on the size of the screen for displaying images, thereby limiting the ability of the user to view or share pictures and/or videos together with others. When the user wants to share the image, the computer and the projection device can be used for the enlarged projection, and the image projection is required at a fixed position, so that the instantness and maneuverability are lacking, which causes the user to use. Therefore, for the user, if the function of image projection can be integrated into the portable electronic device, it can be used to enjoy the enjoyment of the electronic device, and the convenience and utility of the electronic device can be increased. At present, companies such as '3M, TI, Samsung, etc. have already launched mobile phones with built-in projection function. The technology uses the card reader as the source of information, and the optimal size of the weaving surface can reach 3G inches. Nikon's smart and innovative is the world's first digital camera with a built-in projector. It can share the static photos and dynamic movie projections of digital cameras. The projections can reach up to 10,000 inches. However, these designs mostly use a dual-lens architecture, one of which turns to static photography. This adds to the size and weight of the electronic device and complicates the design of the 201245846, deviating from the original design of the portable electronic device. The related art also has other related designs that integrate the image manipulation and image projection functions.

There is a transparent lens with a magnifying function to achieve the function of amplifying the information of the screen. However, in this simple design, since the display size of the transparent lens disposed on the body is still extremely limited, the amplification function of the screen portion information is extremely limited, and the definition is poor, and is not suitable for conference presentation, multi-person viewing, etc. . Therefore, in order to meet the above-mentioned needs of users to share images with multiple people, it is a new research and development direction to provide a portable electronic device that integrates image projection and image capture functions, and has a compact structure and complete functions.

As shown, in order to further reduce the size and cost of the portable electronic device of the present invention, in accordance with a preferred embodiment of the present invention, a reflective switching module 14 is employed to enable the portable electronic device 10 of the present invention to share a lens. The module 11 achieves switching between the image capturing mode and the image projection mode. The image sensor 12 and the micro-projection module 13 are fixed on the same side of the lens module n. The image sensor 12 is preferably disposed on the optical axis 15 of the lens module u. The micro-projection module 13 The optical axis 15 is offset from the optical axis 15 and located between the lens module u and the image sensor 12 . Preferably, the image sensor 12 is located on the imaging surface of the lens module n. Of course, it can be understood that the image sensor 12 may not be disposed on the imaging surface of the lens core group 11 as long as it is located within the maximum focal length range of the lens module 11. The reflection switching module 14 is also disposed between the lens module u and the image sensor 12, and the optical axis 15 of the lens module 11 is located on the opposite side of the micro-projection module 13. The reflection switching unit can be moved between the -first position and the second position, so that the electronic device (7) of the present invention can be switched between the two-like mode and the image projection mode. The reflection switching module Μ can include a reflective single mirror or a reflective prism, and the illustration shows a reflective single mirror. The portable electronic device 10 of the present invention can be in an image capturing mode (refer to the first figure) and an image projection mode (refer to the second figure) by the positional change between the first position and the second position of the reflection switching module 14. ) Switch between. In the image mode shown in the first figure, the reflection switching game is rotated at a first position offset from the optical axis 15 of the lens module η, preferably perpendicular to the image sensor to achieve the lens The module u and the image sensor 12 are directly optically transmitted. In the first position, the center of the element array connecting the image sensor 12 and the dashed line of the lens module 11 constitute the photographic optical axis 15 of the image capturing system. The photographic optical axis is aligned with the object 201245846 and coincides with the optical axis 15 of the lens module 11 such that the reflected light beam from the subject is along the photographic optical axis 15 and the first optical path A indicated by the arrow. An image of the subject is formed on the sensor 12. In the image projection mode shown in the second embodiment, the reflection switching module 14 is rotated to a second position on the optical axis I5 of the lens module 11. In the second position, the reflection switching module 14 is tilted at an angle (for example, a 45 degree angle) on the optical axis 15 of the lens module u to achieve between the lens module 11 and the micro projection module 13. The light path turns. At this time, the image light of the primitive from the micro-projection module 13 can be transmitted to the reflective switching module 14 ′ along the second optical path C parallel to the image sensor 12 , and the image light is then passed by the reflection switching module 14 . The reflection is transmitted along the third optical path B to the lens module 11 to project the image onto the screen by the lens module u. The third optical path B and the first optical path A coincide with each other, but the directions are opposite. The reflection switching module 14 further includes a rotating mechanism (not shown) such that it can rotate about a rotation axis perpendicular to the optical axis 15 of the lens module 11 to deviate or be located at the optical axis of the lens module n. 15. The conversion between the image capture mode and the image projection mode of the portable electronic device of the present invention is achieved. In the image capturing mode shown in the first figure, the reflection switching module 14 is rotated to deviate from the optical axis 15 of the lens module 11 and the first position of the vertical image sensor 12 to move the image sensor 12 The light path exposed to the mirror group u is focused, and the image of the input of the thief is focused and captured and stored by the image sensor I2#. In the image mode of the second ride, the reflection switching module is rotated to a second position in which the mirror group 11 is noisy 15 ± and the collimating group 13 is inclined to allow light from the fine light to pass through the reflection. The 鸠 module Μ is deflected and focused by the lens module 11 and projected onto the screen. The reversal of the reconciliation of the group can be achieved by the rotating mechanism. This part can be easily reached by a person skilled in the art, and the related description is omitted here. The preferred embodiment of the present invention is provided with an image sensor disposed on the optical axis of the module 11 and the micro-projection module 13 is biased on the lens module U and the image sensor. 12 is described as an example, but the present invention is not limited thereto, and other 201245846 embodiments that can achieve function switching can also be implemented. For example, the micro-sensitive sensor 13 can also be disposed on the optical axis 15 of the module u, and the image sensor 12_ is disposed between the mirror display group n and the micro-projection module a. At this time, the rotation switching mode of the reflection switching module 14 and the position of the mirror group: ι are the same, but the directions of the optical paths A, B, and C are opposite. The above-described portable electronic device of the present invention integrates image manipulation and image projection functions into a body to simultaneously have photography and projection. When the manufacturer needs to watch or share the electronic device _ video content with others - the projection zoom function of the electronic device can be directly enabled by means of the cut-off type, without using a computer or other equipment, and is convenient to use, and is not limited The screen size of the electronic device itself. Furthermore, the image capturing system and the image projection system of the portable electronic device of the present invention share a lens module, which can reduce the size, weight and cost of the electronic device, and is compatible with the current portable electronic device, which is light, thin, and versatile. Development trends such as cost reduction.
