ABSTRACT:
An exposure apparatus and method in which an image is formed on a recording medium mounted on a recording stage by irradiating a light beam based on image data from a recording head while the recording head and the recording stage are relatively moved, in the exposure apparatus and method, storing in advance, in a storage section, shift-amount data of a detected displacement of an image-form position with respect to a stage surface of the recording stage in a direction intersecting a direction in which the recording stage moves, which displacement occurs accompanied by movement of the recording stage; carrying out shifting for each of pixels of an image formed by the image data based on the shift-amount data stored in the storage section; and controlling exposure for the recording medium based on image data of the shifted image, is provided to reduce distortion of the image.
