    Abstract: A method and apparatus are provided for efficiently obtaining navigational position of a sensor array based on a correlation between images captured by the sensor array at successive points in time. This is achieved by first acquiring a reference frame through said sensor array, successively acquiring a sample frame through said sensor array. Correlation data representing a relationship between the sample frame and the reference frame is then generated and a displacement of a reference feature contained in both the reference frame and the sample frame is determined based on the correlation data. The correlation surface of the correlation data is modeled as a general two-dimensional Taylor series expansion. The method and apparatus of the present invention can be advantageously employed in a scanning device to provide efficient scheme for obtaining navigational information based on a comparison of image frames captured by a sensor array of the scanning device at successive points in time.

    Abstract: PROBLEM TO BE SOLVED: To solve such a problem that density unevenness may occur when the linearity of PWM to image density is hardly obtained in order to perform correction below one pixel and correction of one-pixel unit for an image half-toned using screen processing, for registration correction.
    SOLUTION: Interpolation is performed so that half dots are always formed with the same manner after the interpolation. By applying a matrix considering the orientation of dots that may be disturbed by the interpolation during the screening processing, conversion while maintaining the vertical relation in the arrangement of the half dots in the sub-scanning direction is performed for the correction below one dot.
