Abstract
An imaging system using an area sensor in which reading of very fine object such as a manuscript, etc. is permitted to be carried out. This imaging system includes an area sensor in which a plurality of pixels are two-dimensionally arranged so that a pixel pitch in an X direction is an integer multiple A of a pixel width and a pixel pitch in a Y direction is an integer multiple B of a pixel length; object driving means for moving an object by the pixel width/length so that in a condition where one of the pixels corresponds to a part of an object, an image of a unit of 1/AB of the part of the object is formed on one of the pixels; and photoelectric conversion control means for allowing the area sensor to carry out photoelectric conversion in a manner synchronized with movement of the object. The system preferably further includes an optical system for carrying out enlargement or contraction adapted to form an image of the unit of 1/AB of the part of the object on the pixel and picture synthesizing means for AB numbered synthesizing image pick-up signals to obtain an image pick-up pattern of the entirety of the object.
