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 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. 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 the quantum efficiency 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.

Abstract: Various embodiments include systems and methods to provide selectable variable gain to signals in measurements using incident radiation. The selectable variable gain may be used to normalize signals modulated in measurements using incident radiation. The selectable variable gain may be attained using a number of different techniques or various combinations of these techniques. These techniques may include modulating a modulator having modulating elements in which at least one modulating element acts on incident radiation differently from another modulating element of the modulator, modulating the use of electronic components in electronic circuitry of a detector, modulating a source of radiation or combinations thereof.
