Abstract: A method for measuring an intensity of ambient light at an electronic device, and a electronic device and a chip are provided. The electronic device includes a screen, and the screen is configured to be deemed at a dimming frequency. The method includes the following. Mixed light including the ambient light and screen leakage light is collected. A DC mean value of the mixed light is obtained. A DC mean value of the screen leakage light is obtained. A DC mean value of the ambient light is determined by subtracting the DC mean value of the screen leakage light from the DC mean value of the mixed light. The DC mean value of the ambient light is indicative of the intensity of the ambient light.

Abstract: Embodiments of the present disclosure provide methods and apparatuses for detecting an ambient light illuminance and for computing a correction coefficient, and an electronic device. The method for detecting an ambient light illuminance includes: filtering ambient light based on a monochromatic channel, such that a quantum effect 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. In solutions of the embodiments of the present disclosure, the photoelectric detection may be equivalent to obtaining an illuminance level of light by convolutional computation based on a spectral luminous efficiency curve, and therefore, when a quantum effect curve for a monochromatic waveband obtained by filtering ambient light based on a monochromatic channel matches the spectral luminous efficiency curve, a reliable spectral luminous efficiency curve can be obtained with a small computing workload.
