1. A method for detecting an ambient light illuminance, comprising:
based on a monochromatic channel, filtering ambient light, such that a quantum efficiency curve of the filtered light matches a spectral luminous efficiency curve; and
performing photoelectric detection on the filtered light to obtain an illuminance level of the ambient light.
