Abstract: A biological data detection method and a biological data detection device are provided. The method determines a variation in light intensity in an ambient environment encompassing a sensing unit at a biological characteristic matching stage compared to a biological characteristic registration stage, the sensing unit having a first value of a parameter at the biological characteristic matching stage and a second value of the parameter at the biological characteristic registration stage; obtaining the first value relative to the second value based on the variation in light intensity in an ambient environment such that image clarity and/or image noise of the biological image generated at the biological characteristic matching stage approximates image clarity and image noise of a biological image generated at the biological characteristic registration stage. The parameter of the sensing unit includes an exposure time and/or an ADC gain coefficient.

Abstract: In keystroke recognition technologies, a method and a module for updating a keystroke reference, and a terminal device are provided. The method for updating a keystroke reference includes: receiving a pressing interrupt sent by a keystroke chip; obtaining a plurality of pressing capacitance values from the keystroke chip, where the plurality of pressing capacitance values include a capacitance value of the keystroke chip at a generation moment of the pressing interrupt and a capacitance value of the keystroke chip at a scanning moment next to the generation moment of the pressing interrupt; and setting a release reference of the keystroke chip according to the plurality of pressing capacitance values, to improve interchangeability and anti-interference of the keystroke chip with no extra burden on a main control chip.
