Abstract: A three-dimensional (3D) scanning system includes a projector that generates an emitted light projected on an object, a reflected light being reflected from the object; a sensor that generates image data according to the reflected light; and a depth processor that generates depth data according to the image data and at least one modified factor representing corresponding deviation amount between the image data and an ideal image data due to a circle of confusion caused by the reflected light passing a lens of the sensor and then irradiating a sense plane of the sensor out of focus.

Abstract: A digital-to-analog converter and an operation method thereof are provided. The digital-to-analog converter includes a current source module, a decoder, a change indicator, and a random number generator. The decoder is coupled to the current source module and receives a digital input signal. The change indicator is coupled to the decoder and provides an indication signal to the decoder. The random number generator is coupled to the change indicator and provides a random number signal to the change indicator. The change indicator generates an indication signal according to the random number signal, and the decoder generates a control signal to the current source module according to the digital input signal and the indication signal, so that the current source module generates an analog output signal corresponding to the digital input signal according to the control signal.

Abstract: A three-dimensional sensing system includes a plurality of scanners each emitting a light signal to a scene to be sensed and receiving a reflected light signal, according to which depth information is obtained. Only one scanner executes transmitting corresponding light signal and receiving corresponding reflected light signal at a time.

Abstract: A card module includes a transceiver, multiple connector interfaces that are each matable with a system connector of a respective type, a detection mechanism and a switching component. The detection mechanism can detect any one of the multiple connector interfaces being mated with the system connector of the respective type. Based on the respective type of the mated system connector, the switching component implements a switch state to connected the mated system connector to the transceiver.
