1. An image processing apparatus configured to perform image processing of converting a resolution of an input image including a plurality of first pixels arranged in a first direction and a second direction intersecting the first direction and thereby acquiring a converted image including a plurality of second pixels arranged in the first direction and the second direction, the image processing apparatus comprising:
a datum point determination unit configured to determine, in a coordinate plane of the input image, coordinates of a datum point for determining pixel values of the second pixels included in the converted image; and
an interpolation unit configured to determine the pixel values of the second pixels based on pixel values of a plurality of reference pixels within a predetermined range based on the datum point among the plurality of first pixels, wherein
coordinates in the first direction of the first pixels present at both ends in the first direction among the plurality of first pixels are set as first direction end portion coordinates and
the datum point determination unit determines coordinates, in the first direction of the datum point, of the second pixels present at both ends in the first direction among the plurality of second pixels to be coordinates shifted to further inside of the input image than the first direction end portion coordinates by a distance longer than 0 and shorter than one pixel of the input image.
