ABSTRACT:
An electromagnetic actuator has a large driving force and a good response speed and an image pickup apparatus obtains an image of a high resolution even by using a solid state image pickup device with a small number of pixels. The actuator comprises permanent magnetic field generating units for generating permanent magnetic fields and a current path forming unit which is relatively movable for the permanent magnetic field generating units and forms a current path which crosses the permanent magnetic fields by a current according to an input control signal. The permanent magnetic field generating units of the actuator generate two permanent magnetic fields in the directions which cross each other by, for example, two pairs of magnets. The current path forming unit has two coils each crossing the permanent magnetic field and winding shafts of those coils exist almost on the same line. A driven member is driven by a relative movement between the magnets and the coils by two electromagnetic forces which are generated between the magnets and the coils. In the image pickup apparatus, first and second electromagnetic actuators are driven and controlled by a control unit, a first parallel flat plate is inclined every four exposures, an image of an object is deviated in four directions, a second parallel flat plate is inclined in four directions every exposure, the image of the object is deviated in four directions, and the image data obtained by the exposure of four times is synthesized, thereby forming synthetic image data of one picture plane.
