Abstract

A camera assembly includes an infrared laser system, a camera, a flicker detector, and a light-filtering piece. The infrared laser system has an out-light surface. Infrared emitted by the infrared laser system propagates outside of the camera assembly through the out-light surface. The out-light surface of the infrared laser system, an in-light surface of the camera, and an in-light surface of the flicker detector face a same direction and are staggered from each other. The light-filtering piece covers the in-light surface of the flicker detector and is configured to filter out infrared. The flicker detector is configured to detect a frequency of visible light in external light filtered by the light-filtering piece. When the camera assembly is applied to an electronic device, photographing performance of the electronic device is good.

Claims (39)

1 . A camera assembly, comprising

an infrared laser system comprising an out-light surface and configured to emit infrared light that propagates outside of the camera assembly through the out-light surface;

a camera comprising a first in-light surface;

a flicker detector comprising a second in-light surface, wherein the out-light surface, the first in-light surface, and the second in-light surface face a same direction and are staggered from each other such that the out-light surface, the first in-light surface, and the second in-light surface do not overlap;

a mounting bracket comprising a first through hole, wherein the flicker detector is partially disposed in the first through hole such that the second in-light surface of the flicker detector is located inside the first through hole; and

a light-filtering piece comprising:

a light-filtering substrate comprising:

a first surface; and

a second surface disposed opposite to the first surface;

a light-filtering layer disposed on each of the first surface and the second surface of the light-filtering substrate and configured to filter out the infrared light having a wavelength ranging from 800 nanometers to 1600 nanometers; and

a base configured to:

enclose and connect to a peripheral side surface of the light-filtering substrate;

cover the second in-light surface of the flicker detector; and

filter out the infrared light from external light, wherein the flicker detector is configured to detect a frequency of visible light in the external light.

2 . The camera assembly of claim 1 , wherein the light-filtering layer comprises a plurality of sequentially stacked film-coated layers, and wherein a material of the film-coated layers comprises titanium dioxide.

3 . The camera assembly of claim 1 , wherein the light-filtering layer comprises a plurality of sequentially stacked film-coated layers, and wherein a material of the film-coated layers comprises silicon dioxide.

4 . The camera assembly of claim 1 , wherein a material of the light-filtering substrate comprises resin, and wherein a thickness of the light-filtering substrate ranges from 0.05 millimeters to 0.15 millimeters.

5 . The camera assembly of claim 1 , wherein the base is a frame-shaped structure.

6 . The camera assembly of claim 1 , wherein the camera assembly further comprises an ambient light sensor configured to detect a color temperature of the external light, and wherein the ambient light sensor and the flicker detector are a two-in-one component.

7 . The camera assembly of claim 1 , wherein the camera assembly further comprises the mounting bracket having an accommodation space, wherein the infrared laser system is disposed in the accommodation space, wherein the mounting bracket is provided with a second through hole, and wherein the second through hole communicates with the accommodation space and is configured to allow the infrared light to pass through.

8 . The camera assembly of claim 1 , wherein the mounting bracket comprises an accommodation space, wherein the mounting bracket is provided with the first through hole and a second through hole that are spaced and communicate with the accommodation space, wherein the infrared laser system and the flicker detector are located in the accommodation space, wherein the first through hole is configured to allow the external light to pass through to irradiate the flicker detector, and wherein the second through hole is configured to allow the infrared light to pass through.

9 . The camera assembly of claim 8 , wherein the flicker detector is entirely disposed in the first through hole.

10 . The camera assembly of claim 8 , wherein the mounting bracket comprises a top wall, wherein an opening of the first through hole and an opening of the second through hole are located in the top wall, and wherein the light-filtering piece is mounted on the top wall and covers a part of the first through hole.

11 .
