Embodiments of the present application provide a method for fingerprint identification, and electronic device. The method includes: acquiring a first image collected by a fingerprint sensor at a first exposure time; determining whether to acquire a second image collected by the fingerprint sensor at a second exposure time according to the first image, where the second exposure time is continuous with the first exposure time, and a length of the second exposure time is greater than or equal to a length of the first exposure time; performing fingerprint identification according to the first image, or, the first image and the second image. The method, and electronic device of the embodiments of the present application can take into account an unlocking rate and unlocking time, thereby improving unlocking experience of a user.

Method and apparatus for fingerprint identification, and electronic device

A method for fingerprint detection, which may more easily reduce an influence of a brightness change of a display screen on the fingerprint detection and improve performance of the fingerprint detection. The method for the fingerprint detection includes: receiving a synchronization signal of a display screen, the synchronization signal being configured to trigger a pixel array of a fingerprint sensor to expose, where a period of the synchronization signal is synchronized with a dimming period of the display screen, and the dimming period includes a bright period and a dark period; exposing each row of pixels in the pixel array in sequence based on triggering of the synchronization signal, so that a position of the pixel whose exposure time corresponding to the dark period in the pixel array is constant, where data of each row of the pixels after exposure is configured to obtain a fingerprint image.

Some embodiments of the present disclosure relate to biometric characteristic detection technology, which provide a method and chip for biometric characteristic acquisition, and a computer readable storage medium. The method for biometric characteristic acquisition includes: acquiring a plurality of configuration parameters, where the plurality of configuration parameters include a first exposure duration, parameters defining a first region and a target photosensitive value, where the first region is a local region in a photosensitive region of the chip for biometric characteristic acquisition; exposing the first region according to the first exposure duration, and acquiring a photosensitive value of the first region; determining a second exposure duration required to acquire the target photosensitive value in the photosensitive region according to the photosensitive value of the first region and the first exposure duration; and acquiring a biometric image according to the second exposure duration.

Method and chip for biometric characteristic acquisition, and computer readable storage medium

Provided are a power-on processing method and apparatus of a terminal device, and a terminal device, and the method includes: detecting whether a fingerprint input operation is performed on the fingerprint device, when the operating system of the terminal device is in a non-working state; controlling the fingerprint device to collect fingerprint data corresponding to the fingerprint input operation when it is detected that the fingerprint input operation is performed on the fingerprint device; detecting whether the fingerprint input operation triggers the power button, when it is detected that the fingerprint input operation is performed on the fingerprint device; and transmitting the fingerprint data collected by the fingerprint device to the operating system for security verification, when it is detected that the fingerprint input operation triggers the power button.

Power-on processing method and apparatus of terminal device, and terminal device

A one-button power-on processing method and a terminal thereof are provided. The method includes: judging whether pressing a power button at a current time triggers one-button power-on of a terminal when it is detected that the power button is pressed at the current time; and sending the biometric feature data acquired by the biometric feature identification module to an operating system of the terminal for one-button power-on processing if pressing the power button at the current time triggers one-button power-on of the terminal. In this way, the terminal is powered on by a user by performing the press operation once. This enhances convenience, and effectively improves user experience of the terminal.

One-button power-on processing method and terminal thereof

A fingerprint detection apparatus and a terminal device having a fingerprint identification function are disclosed. The terminal device includes: a glass cover, configured to provide a touch interface; a liquid crystal panel, located below the glass cover; a backlight module, located below the liquid crystal panel; and a light-emitting component, located below the glass cover, wherein the light-emitting component and the liquid crystal panel are staggered from each other, and the light-emitting component is configured to emit a light to illuminate the finger to generate a returned light, wherein the returned light is used for the terminal device to perform the fingerprint identification on the finger.
