Embodiment Construction

[0017] The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with accompanying drawings.

[0018] The portable electronic device with image capture and image projection functions of the present invention can simultaneously achieve the two functions of image capture and image projection. The captured images can be static images or video images, and these images and other external images can be enlarged and projected for display through the image projection function.

[0019] The portable electronic device with image capture and image projection functions of the present invention adopts a shared lens module to reduce the overall size, weight and cost of the device. The lens module functions as an objective lens system in the image capture mode, and as a projection lens system in the image projection mode.

[0020] see figure 1 , which schematically shows...

Abstract

The invention relates to a portable electronic device with image capturing and image projection functions, comprising a lens module with an optical axis, an image sensor, a miniature projection module with a light valve, and a reflection switching module. The image sensor and the miniature projection module are arranged at the same side of the lens module, one of the image sensor and the miniature projection module is arranged at the optical axis of the lens module, and the other one of the image sensor and the miniature projection module is arranged between the lens module and one of the image sensor and the miniature projection module in a biased manner relative to the optical axis of the lens module. The reflection switching module is arranged between the lens module and one of the image sensor and the miniature projection module and can move between a first position and a second position, so that the portable electronic device can be switched between the image capturing mode and the image projection mode. In the first position, the reflection switching model deviates from the optical axis of the lens module, so that the light path direct transmission is realized between the lens module and one of the image sensor and the miniature projection module is realized. In the second position, the reflection switching module is obliquely positioned at the optical axis of the lens module, so that the light path indirect transmission is realized between the lens module and the other one of the image sensor and the miniature projection module.

Description

technical field [0001] The invention relates to the fields of image capture and image projection, in particular to a portable electronic device with image capture and image projection functions. Background technique [0002] In recent years, with the advancement of microelectronics technology, portable electronic devices, especially palm-sized electronic devices, have become more advanced and more functional. For example, a portable electronic device may simultaneously have the functions of calling, global positioning, photography, web browsing, and / or multimedia playback. Currently widely used portable electronic devices include mobile phones (Mobile Phone), personal digital assistant (PDA, Personal Digital Assistant), digital camera (Digital Camera), laptop computer (Laptop Computer), etc., all of which have the function of image capture . However, due to the small size of these portable electronic devices, the screen size for displaying images is relatively limited, the...
