    Abstract: An electronic device comprising: a clock pin; at least one data pin; a storage device, configured to store at least one program; a processing circuit, coupled to the data pin. A device ID setting method is performed when the processing circuit executes the program stored in the storage device. The device ID setting method comprises; (a) recording connections between pins of a first electronic device and pins of the electronic device by the electronic device, wherein the first electronic device comprises at least one data pin; and (b) applying the connections between the pins of the first electronic device and the pins of the electronic device as a device ID of the first electronic device by the electronic device.

    Abstract: 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.

    Abstract: There is provided a pupil tracking device including an active light source, an image sensor and a processing unit. The active light source emits light toward an eyeball alternatively in a first brightness value and a second brightness value. The image sensor captures a first brightness image corresponding to the first brightness value and a second brightness image corresponding to the second brightness value. The processing unit identifies a brightest region at corresponding positions of the first brightness image and the second brightness image as an active light image.
