ABSTRACT:
When a scan line is interpolated, pixels on scan lines above and below the scan line which are referenced is interpolated in the horizontal direction. These pixels on the upper and lower scan lines are divided into blocks. Correlations between the upper and lower blocks with respect to a target pixel to be interpolated are calculated. Based on an evaluating function which is formed based on the correlations but is corrected with reference to the distance (or the direction) from the target pixel to each of the blocks, an optimal interpolating direction is selected. In addition, the difference in the pixel data between the interpolated pixel and each of the pixels around the interpolated pixel is checked in order to find interpolation errors. When an interpolating pixel data is determined to be erroneous, the pixel is interpolated using the pixels of data above and below the pixel.
