1. An image processing apparatus comprising:

  • an edge information extracting unit that extracts edge information from an image signal that has not yet subjected to an interpolation process; and

    an edge correcting unit that performs edge correction on the basis of the edge information extracted by the edge information extracting unit,wherein the edge correcting unit performs the edge correction in which a signal level of a target pixel is replaced with a maximum value of signal levels of a plurality of peripheral pixels positioned on a periphery of the target pixel when a sum of the signal level of the target pixel and the edge information is more than the maximum value, andwherein the edge correcting unit performs the edge correction in which the signal level of the target pixel is replaced with a minimum value of the signal levels of the plurality of peripheral pixels when a sum of the signal level of the target pixel and the edge information is less than the minimum value.
