HEAD OF IMAGING APPARATUS, AND IMAGING APPARATUS

摘要

A head of an imaging apparatus of an embodiment includes: an imaging element having a rolling shutter function and configured to output an analog image signal in correspondence with a light amount of an object of shooting; an analog amplifier configured to amplify or attenuate a signal level of the analog image signal outputted from the imaging element in correspondence with an inputted gain to output the amplified or attenuated analog image; a converter configured to convert the amplified or attenuated analog image signal outputted from the analog amplifier into a digital signal to output the digital signal, and clip the digital signal of which the signal level exceeds a maximum output level, at the maximum output level; and a gain controller configured to control a gain inputting to the analog amplifier in a range including a minus gain.
