Camera and photosensitive integrated optical device

The present invention relates to an optical device, and more particularly to an imaging and photosensitive integrated optical device having both an image capturing function and an inductive function.

In recent years, with the advancement of technology, various electronic devices have been designed to be lightweight and easy to carry, so that users can conduct business or entertainment activities by electronic devices anytime and anywhere. Taking image capture devices as an example, image capture devices have recently been widely used in various fields, such as portable electronic devices such as smart phones, tablet computers, and wearable devices, which have the advantages of small size and convenient portability. The image capture operation can be performed at any time as needed, and the image obtained by the shooting can be stored. Alternatively, it can be further uploaded to the Internet through a mobile network for data transmission.

On the other hand, sensing devices have also been developed to maximize user convenience and make the system operate more smoothly. However, the technology of the sensing device and the image capturing device is becoming more and more mature, so the overall structure is complicated and the volume is large. So how to integrate The image capturing device and the miniaturization with the sensing device have become important issues.

Please refer to FIG. 1 , which is a side cross-sectional view showing the structure of a conventional image capturing device. The conventional image capturing device 1 includes an optical lens 11 , an optical sensing element 12 , and a housing 13 , and the optical lens 11 is composed of a single lens sheet, which can pass the external light L and enter the conventional image capturing device 1 . internal. The optical sensing component 12 corresponds to the optical lens 11 , and can sense the corresponding optical signal L through the optical lens 11 to generate a corresponding image signal for display connected to the display of the image capturing device 1 (not shown). An image of an image signal. The housing 13 functions to accommodate the optical lens 11 and the optical sensing element 12, and is positioned such that the optical lens 11 and the optical sensing element 12 operate normally, and the housing 13 has an opening 131 for revealing optical The lens 11 is outside, and the external light L is passed through the optical lens 11. The optical lens 11 has an optical axis A and a field of view (FOV), the viewing angle θ of which determines the viewing area of the image capturing device 1 , and the optical lens 11 is a circular lens, and The diameter is 2. R. Wherein, the larger the size of the optical lens 11, the larger the viewing angle θ, and the larger the viewing area, and the size of the opening 131 is slightly larger than the effective optical size or optical aperture of the optical lens 11.

When the image capturing device 1 selects the optical sensing component 12 having a small pixel size, the external light L is not easily incident on the optical sensing component 12, so a light guiding component needs to be disposed between the optical lens 11 and the optical sensing component 12. (not shown) to direct external light L to the optical sensing element 12. In general, when the angle of view θ is larger, the position of the intersection point (defined as a turning point) of the external light L passing through the optical lens 11 is closer to the optical lens 11. In this case, the image capturing device 1 must be set. The long light guiding element can surely guide the external light L to the optical sensing element 12. However, longer light guiding elements are less efficient and costly, and The length of the casing 13 is made large.
