Abstract

A focus assist circuit for a viewfinder, including a video amplifier configured to amplify a video signal, a video gain controller configured to adjust gain of the video amplifier to provide peaking headroom, and a peaking processor configured to adjust the amplified video signal. The focus assist circuitry may facilitate focusing a camera lens by proving peaking headroom for a peaking signal that is combined with an amplified signal. The peaking headroom limits the gain applied to a video signal in order to reduce distortions in the peaks. A user interface may include input controls configured to limit the gain of the of a video amplifier.
