PURPOSE:To make a reproduced mapping function accurate by storing a bias value which is necessary to reproduced the mapping function on a mapping plane by means of integrating the differential value in the extraction of information by mapping obtained by recording the mapping function on a mapping plane with the differential value. CONSTITUTION:The mapping function, corresponding to the coordinate of an extracted point in an object plane, is generated every extracted point and the generated mapping function is written on the mapping plane in such a way as the said mapping function is made to have a specified width and the said mapping is made to have the suppression area having the characteristics opposite to the width area on both sides of the above-mentioned width. This is an information extracting method by mapping in which the information which the respective extracted points mean is extracted from the mutual relation between the mapping plane and the mapping function and by adding the differential value to the above-mentioned width and the edge point position of the suppression area and in tegrating the differential value, the rewrite is executed on the mapping plane. In the information extracting method by mapping like this, the bias value necessary for integration is made to be written on the mapping plane. Namely by writing the bias value necessary for integration on the mapping plane, the integration using the bias value is executed, so that the reproduction can be executed. |
