Abstract

Abstract An imaging apparatus is disclosed which is integrally provided with two image pickup systems for respectively converting subject light into image signals and two displays for respectively displaying images relative to the image signals obtained by the two image pickup systems. In the disclosed imaging apparatus, since the operations of the two image pickup systems are synchronized, it is not necessary to insert an element, such as a prism, in each optical path. Further, since a common signal processing circuit is provided for performing predetermined processing of the image signals outputted from the two image pickup systems, the size of the imaging apparatus is reduced.
