Apparatus and methods for averaging image signals in a media processor

摘要

A first signal and a second signal are obtained using a first and second image sensors, respectively. The first signal and the second signal are converted from analog to digital form. The first signal and the second signal are then averaged to improve the signal to noise ratio of the resulting signal. The first signal may be obtained using a channel corresponding to a first channel. The second signal may be obtained using a channel corresponding to a second channel. Further, a third signal may also be obtained using a channel corresponding to a third channel. Then, the first, second, and third signals may be averaged to generate an averaged signal.
