IMAGING APPARATUS WITH FOCUS ASSIST FUNCTION

摘要

An imaging apparatus with a focus assist (FA) function includes an imager configured to obtain an image signal from a subject formed by a lens, a high-frequency signal extractor configured to extract a high-frequency signal from the image signal, a modulation level calculator configured to determine a magnitude of a modulation level signal in each of regions, into which a screen of the image signal is divided, in accordance with an amplitude level of the high-frequency signal, a level modulator configured to modulate an amplitude level of the high-frequency signal using the modulation level signal to obtain an FA signal, and an FA signal synthesizer configured to synthesize the FA signal with the image signal to output a resultant signal.
