Abstract
Incident light is refracted by a planar plate 30 which is fixedly slanted with respect to the optical axis, before being imaged on an image receiving surface of an image sensor 10. The planar plate 30 rotates about the optical axis or an axis parallel to the optical axis. In accordance with the rotational movement of the planar plate, the incident light imaged position moves on the image receiving surface of the image sensor 10. Light portions originally imaged on gap areas between neighboring light pick up elements of the image sensor 10 move into the light pick up elements. The image sensor can therefore pick up those image portions which are originally imaged on the gap areas and therefore which may not be picked up by the image sensor. Picking up an image every time when its image position moves and composing thus obtained images by the composing device 70 can obtain a high quality image which has little area of image portions which are imaged on the gap areas between the light pick up elements and therefore which are not picked up.
