Abstract: The present disclosure relates to a multi-mode vehicle window control method and device. The method combines voice recognition and computer vision technologies, detects a user's voice wake-up word using a vehicle-mounted microphone, turns on the vehicle-mounted camera to detect the user's face and head, analyzes the user's gaze, face pose, and head posture to estimate the user's attention region, and aligns the attention region with a vehicle body coordinate system. Intelligent control of a vehicle window is realized according to specific coordinates of an attention area on the vehicle window. Even if the user's face or eyes are not detected, the vehicle window may be operated accurately by determining the user's intention through the face or head pose.

Abstract: An active pixel circuit, an image sensor and an electronic device are disclosed. The active pixel circuit has a photodiode and at least three MOS transistors. At least one of the MOS transistors serves as a transfer transistor, and at least another one of the MOS transistors serves as a reset transistor. Moreover, at least yet another one of the MOS transistors serves as other transistor(s). The transfer transistor has a higher threshold voltage and smaller off-state leakage current under operating voltage than each other MOS transistor. With this design, the high-threshold, low-leakage characteristics of the transfer transistor reduce storage distortion of the photodiode and signal readout distortion, resulting in less read noise and lower power consumption of the active pixel circuit. Meanwhile, the low-threshold, high-leakage (i.e., high-on-current) characteristics of the other MOS transistors impart an increased reading speed of the active pixel circuit.
