摘要
A circuit for determining the median dark level of an image sensor, the circuit comprises a first circuit for comparing a current pixel value and a cumulative median; a storage element for storing the cumulative median level; and a second circuit which utilizes the first circuit for adjusting the cumulative median based on the current pixel level input for updating the cumulative median dark level.
