Camera assembly and electronic device

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.
