Abstract
Provided are a method for fingerprint collection and related products. The method includes the following. In response to a receipt of a fingerprint collection instruction, an intensity of each of ambient lights having at least two different frequencies at a current time point is determined via an optical sensor of the terminal. A target frequency is determined, where the target frequency is a frequency of one ambient light having a lowest ambient light intensity among the ambient lights having the at least two different frequencies. Control light emission of an internal light source of an optical fingerprint sensor of the terminal at least according to the target frequency so as to collect fingerprint data via the optical fingerprint sensor.
Claims20
A method for fingerprint collection, comprising:
- determining, in response to receiving a fingerprint collection instruction, an intensity of each of ambient lights having at least two different frequencies at a current time point via an optical sensor of a terminal;
- determining a target frequency, the target frequency being a frequency of one ambient light having a lowest ambient light intensity among the ambient lights having the at least two different frequencies;
- and
- controlling light emission of an internal light source of an optical fingerprint sensor of the terminal at least according to the target frequency so as to collect fingerprint data via the optical fingerprint sensor.
A terminal, comprising:
- an optical sensor configured to detect, in response to receiving a fingerprint collection instruction, an intensity of each of ambient lights having at least two different frequencies at a current time point;
- an application processor (AP), configured to determine a target frequency, the target frequency being a frequency of one ambient light having a lowest ambient light intensity among the ambient lights having the at least two different frequencies;
- and
- an optical fingerprint sensor comprising an internal light source and configured to collect fingerprint data when the internal light source is controlled by the AP to emit lights at least according to the target frequency.
A non-transitory computer readable storage medium, configured to store executable program codes, wherein the executable program codes, when executed, are operable with a processor to:
- determine, in response to a receipt of a fingerprint collection instruction, an intensity of each of ambient lights having at least two different frequencies at a current time point via an optical sensor of the terminal;
- determine a target frequency, the target frequency being a frequency of one ambient light having a lowest ambient light intensity among the ambient lights having the at least two different frequencies;
- and
- control light emission of an internal light source of an optical fingerprint sensor of the terminal at least according to the target frequency so as to collect fingerprint data via an optical fingerprint sensor.
