1. An image processing device comprising:

  • a dividing process section which divides inputted image data into a plural pieces of divided image data; and

    a plurality of upscaling process sections which enhance resolution of each of the plural pieces of divided image data, respectively,the dividing process section producing the plural pieces of divided image data so that each one of the plural pieces of divided image data shares a portion with its adjacent one of the plural pieces of divided image data, so that border areas of that one and its adjacent one of the plural pieces of divided image data overlap each other,each of the plurality of upscaling process sections including;

    a difference operation section which carries out a difference operation process in which a gradation value of a target pixel is calculated by an operation with use of differentiation or difference of gradation values in vicinity to the target pixel, the gradation value of the target pixel being used for extracting an edge of an article pictured in an image,an averaging process section which carries out an averaging process in which an average value of the gradation values in vicinity to the target pixel is calculated as a gradation value of the target pixel;

    a correlation operation section which carries out calculation process for obtaining a correlation value indicative of a correlation between difference image data and averaged image data, the difference image data being produced by subjecting the plural pieces of divided image data to the difference operation process, and the averaged image data being produced by subjecting the plural pieces of divided image data to the difference operation process and the averaging process; and

    an interpolation process section which carries out an interpolation process on the plural pieces of divided image data with use of an interpolation method which is selected in accordance with the correlation value.
