Abstract

The invention is applicable to the technical field of image sensing, and provides an optical biosensor and a power-saving control method and system thereof, and the power-saving control method comprises the steps of controlling the optical biosensor to enter a sleep mode when the optical biosensor is in a standby state, and enabling the optical biosensor to stop scanning in the sleep mode; when the optical biosensor is in a wake-up state, controlling the optical biosensor to enter a touch detection mode, and enabling the optical biosensor performs intermittent scanning in the touch detection mode; judging whether a touch signal is detected in a preset area or not according to the scanning result; and if a touch signal is detected in a preset area, controlling the optical biosensor to enteran information acquisition mode, and enabling the optical biosensor to continuously scan the preset area in the information acquisition mode. According to the embodiment of the invention, the workingmode of the optical biosensor can be controlled according to different working states of the current terminal, and the power consumption of the optical biosensor is reduced.

Description

technical field [0001] The invention belongs to the technical field of image sensing, and in particular relates to an optical biosensor and its power saving control method and system. Background technique [0002] With the continuous development of science and technology, intelligent terminals such as smart phones and tablet computers are constantly updated. In recent years, biometric image sensing technologies such as fingerprint recognition and facial recognition have been widely used in various smart terminals, improving the security performance of smart terminals. [0003] However, the biometric image sensing function of the existing smart terminals is usually continuously turned on, and the power consumption is high, which greatly reduces the battery life of the smart terminal. Contents of the invention [0004] In view of this, an embodiment of the present invention provides an optical biosensor and its power-saving control method and system, so as to solve the prob...
