Title:
METHOD FOR DYNAMICALLY ADJUSTING EXPOSURE PARAMETER OF SPECTRAL SENSOR, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/267612
Kind Code:
A1
Abstract:
Provided in the present application are a method for dynamically adjusting an exposure parameter of a spectral sensor, and an electronic device. The method comprises: an electronic device determining whether a clear value is less than or equal to a first threshold value; if the clear value is less than or equal to the first threshold value, the electronic device determining whether an analog gain of a spectral sensor reaches a second threshold value, if so, the electronic device extending the exposure time of the spectral sensor, and if not, the electronic device increasing the analog gain of the spectral sensor; and if the clear value is greater than the first threshold value, the electronic device determining whether the exposure time of the spectral sensor reaches a fourth threshold value, which is a lower-limit threshold value of the exposure time of the spectral sensor, and if so, the electronic device decreasing the analog gain of the spectral sensor, and if not, the electronic device shortening the exposure time of the spectral sensor.
