    Abstract: A camera tuning circuit has a first storage space, a second storage space and a controller. The first storage space stores a first reference camera correction setting for a reference camera module under a first color temperature. The second storage space stores a second reference camera correction setting for the reference camera module under a second color temperature, wherein the second color temperature is different from the first color temperature. The controller receives a default camera correction setting of a target camera module, the first reference camera correction setting, and the second reference camera correction setting, and generates a tuned camera correction setting for the target camera module according to the default camera correction setting, the first reference camera correction setting, and the second reference camera correction setting.

    Abstract: An active noise control system and associated auto-selection method for modeling a secondary path for the active noise control system are provided. The method includes the steps of: receiving a reference signal; filtering the reference signal with a secondary-path estimation filter to obtain a filtered reference signal, wherein the secondary path estimation filter is determined from a plurality of candidate secondary-path estimation filters; filtering the reference signal with an adaptive filter to provide a compensation signal; sensing a residual noise signal at a listening position of the active noise control system; and adapting filter coefficients of the adaptive filter according to the residual noise signal and the filtered reference signal.

    Abstract: An earpiece of a headset uses a first signal and a second signal received from an in-ear microphone and an outside microphone, respectively, to enhance microphone signals. The in-ear microphone is positioned at a proximal side of the earpiece with respect to an ear canal of a user, and the outside microphone is positioned at a distal side of the earpiece with respect to the ear canal. A processing unit includes a filter, which digitally filters out in-ear noise from the first signal using the second signal as a reference to produce a de-noised signal to thereby enhance the microphone signals.
