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.

[ What is claimed is:] [1.] An imaging apparatus comprising:imaging means for picking up incoming original image light to output an original image signal, the imaging means including an imaging device having a plurality of light-receiving regions arranged in a predetermined array on a two-dimensional plane;an optical system disposed on a light-incoming side of the imaging means, including a variable spatial filter, for collecting the incoming original image light to focus on the light-receiving regions of the imaging device;shifting means for relatively shifting a light-receiving position between a plurality of predetermined shifting positions on the imaging device, thereby receiving the incoming original image light on the imaging device at the light-receiving position;judging means for determining based on an imaging mode of an image whether to permit or to prohibit shifting of the light-receiving position by the shifting means;image generating means responsive to outputs from the imaging means and judging means for generating an output image signal based on the original image signal; andimaging control means for, during permission of shifting the light-receiving position, causing the shifting means to shift the light-receiving position for the original image light to predetermined shifting positions a predetermined number of times, causing the imaging means to pick up the original image at each shifting position and causing the image generating means to generate an output image signal based on a plurality of original image signals, andfor, during prohibition of shifting the light-receiving position, disabling the shifting means for fixing the light-receiving position for the original image light to any one of the shifting positions while causing the imaging means to pick up a single original image and then, causing the image generating means to generate an output image signal based on the single original image signal,wherein the variable spatial filter is responsive to an output from the judging means for attenuating a predetermined spatial frequency component of the original image light incoming into the optical system, anda smaller amount of the spatial frequency component is attenuated when the shifting means is permitted to shift the light-receiving position than when the shifting means is prohibited from shifting the light-receiving position.
