Abstract
A level difference of an upper pixel on an upper scanning line placed over an attentional pixel and a lower pixel on a lower scanning line placed under the attentional pixel, a level difference of the upper pixel and a lower left pixel, a level difference of the upper pixel and a lower right pixel, and a level difference of the lower pixel and an upper left pixel and a level difference of the lower pixel and an upper right pixel are derived. These level differences are compared with each other, and a line having a smallest level difference is detected and an effective interpolation line information is generated. Moreover, the level difference of the upper pixel and lower pixel is compared with the level difference of the upper right pixel and lower left pixel, and a smaller is set as a first interpolation line. In a similar manner, a second interpolation line is derived, and an ultimate interpolation line is selected from the first interpolation line, the second interpolation line and a line connecting the upper pixel and lower pixel on the basis of the effective interpolation line information.
