Still image pickup device with two-dimensionally displaceable image pickup surface

An apparatus comprising:

• means for forming an object image on a predetermined plane;
• image pickup means having an image pickup surface positioned substantially on said predetermined plane, said image pickup means producing an electrical image signal from light incident thereon;
• moving means for two-dimensionally moving said image pickup means along said predetermined plane in an image detection area substantially larger than the area of said image pickup surface;
• memory means;
• processing means for processing said electrical image signal and storing the processed signal in said memory means;
• control means for controlling said moving means to move and stop said image pickup means in said detection area so as to position and stop said image pickup surface successively in a plurality of non-overlapping positions in said detection area, and for controlling said image pickup means and said processing means such that said image pickup means produces an electrical image signal at each of said plurality of positions and said processing means processes each electrical image signal and stores the corresponding processed signal in said memory means;
• and
• synthesizing means for synthesizing an image signal representing the portion of the object image corresponding to said plurality of positions on the basis of the processed signals stored in said memory means.
