Abstract

An image processing system and an imaging device are provided. The image processing system includes a circuit board, an ambient light sensor, a light guide, a camera sensor and a camera lens. The ambient light sensor is integrated on the circuit board. An output end of the light guide is connected to the ambient light sensor to guide light to a detecting part of the ambient light sensor. The camera sensor is integrated on the circuit board. The camera lens is connected to the camera sensor. In the present disclosure, light guide is optically coupled with the ambient light sensor, such that a field of view of the ambient light sensor can be controlled to enhance color performance. Further, the light guide can provide spatial selectivity for the ambient light sensor while improving system integration and minimizing impact on appearance of the imaging device.

Claims (22)

1. An image processing system, comprising:

a circuit board;

an ambient light sensor integrated on the circuit board;

a light guide, an output end of the light guide being connected to the ambient light sensor to guide light to a detecting part of the ambient light sensor;

a camera sensor integrated on the circuit board; and

a camera lens connected to the camera sensor;

wherein the light guide is a periscope structure;

the light guide is an optical fiber bundle.

2. The image processing system as described in claim 1 , further comprising:

a lens connected to an input end of the light guide,

wherein the camera lens is arranged at a side of the lens facing away from the ambient light sensor.

3. The image processing system as described in claim 1 , wherein the light guide is made of glass.

4. The image processing system as described in claim 1 , wherein the light guide is made of plastic.

5. The image processing system as described in claim 1 , wherein the camera lens is arranged at a side of an input end of the light guide, and the input end of the light guide is spaced apart from the camera lens.

6. An imaging device, comprising an image processing system, the image processing system comprising:

a circuit board;

an ambient light sensor integrated on the circuit board;

a light guide, an output end of the light guide being connected to the ambient light sensor to guide light to a detecting part of the ambient light sensor;

a camera sensor integrated on the circuit board; and

a camera lens connected to the camera sensor;

wherein the light guide is a periscope structure;

a cover formed with an opening, wherein an input end of the light guide is aligned with the opening.
