Abstract
A single imaging apparatus is adapted to pick up both a motion image and a still image. In an imaging apparatus 1, image light from an object is separated into multiple monochromatic image light components by an optical system 3 and then imaged by an imaging means 4 for generation of an original image signal. The imaging apparatus 1 switches an imaging mode depending upon an output mode. The optical system 3 switches the sate of a variable spatial filter 18 depending upon an imaging mode thereby changing an effect for limiting the spatial frequency. In an output mode for motion images, an interpolative synthesizer circuit 7 generates the output image signal from a single original image signal. In an output mode for still image, an image shift mechanism 19 parallely shifts the optical axis of the incoming image light while the imaging means captures the original image light multiple times so that an output image is produced from these original image signals. An amount of attenuation of the filter 18 in the output mode for motion images is greater than that for an equivalent spatial frequency component in the output mode for still image.
