摘要: The present disclosure provides a time delay integration (TDI) sensor using a rolling shutter. The TDI sensor includes multiple pixel columns. Each pixel column includes multiple pixels arranged in an along-track direction, wherein two adjacent pixels or two adjacent pixel groups in every pixel column have a separation space therebetween. The separation space is equal to a pixel height multiplied by a time ratio of a line time difference of the rolling shutter and a frame period, or equal to a summation of at least one pixel height and a multiplication of the pixel height by the time ratio of the line time difference and the frame period. The TDI sensor further records defect pixels of a pixel array such that in integrating pixel data to integrators, the pixel data associated with the defect pixels is not integrated into corresponding integrators.

摘要: There is provided an optical sensor that acquires a first image frame corresponding to a first flicker period and acquires a second image frame corresponding to a second flicker period. The optical sensor adds the first image frame to the second image frame to generate a sum of image frames for the motion detection. Or, the optical sensor respectively adds pixel data of every two pixels in neighboring rows of the first image frame and the second image frame to generate a low-resolution image frame for the motion detection.

摘要: A steering wheel and a heat-conducting device are provided. The steering wheel includes a body, a handle, a heating device, an electronic control unit, a heat-conducting member and a base. The handle is adjacent to the body, and the heating device is disposed in the handle and receives a driving signal to generate heat accordingly. The electronic control unit is electrically connected to the heating device through a driving wire, and provides the driving signal to the heating device. The heat-conducting member forms a waste heat path, and the heat-conducting member and the heating device are located at different locations in the handle. The base is connected to the electronic control unit, collects waste heat from the electronic control unit, and is connected to the heat-conducting member through a heat dissipation wire to transfer the waste heat to the heat-conducting member.
