Abstract: There is provided an image sensor for exposing a plurality of pixel rows within a frame period using a rolling shutter. The image sensor includes a processor for calculating bright-dark distribution patterns of image frames. The processor further adjusts the frame period to be substantially identical to a predetermined period by changing a total number of exposed line times within the frame period when a difference between the bright-dark distribution patterns of two image frames is larger than a predetermined threshold.

Abstract: A direction control apparatus with a sensor, a method for determining a driver status using the driving control apparatus, and a system for determining the driver status are provided. The direction control apparatus includes at least a pressure sensor to sense a plurality of pressure values applied to multiple positions of the direction control apparatus. When the pressure values are received by a controller of the apparatus, the driver status can be determined according to a change of pressure values over time, or further a change of the positions where pressure is applied. The system can connect with an autopilot system and an alarm system of a vehicle via the controller. Therefore, the system incorporates an autopilot system and issues an alarm when the driver status is determined to be abnormal.

Abstract: There is provided a touch detection circuit including a charging circuit, a discharging circuit, a counter and a processor. The charging circuit charges a detection capacitor within a charging interval using different currents. The discharging circuit discharges the detection capacitor within a discharging interval using different currents. The counter counts the charging interval and the discharging interval. The processor subtracts a baseline time from a counted charging time and a counted discharging time to cancel the noise interference.
