Data conversion circuits and methods of data conversion that enable to keep the continuity in the converted data while reducing a required memory capacity are disclosed. An exemplary conversion circuit includes a LUT that stores representative correction values and an interpolation circuit that generates conversion data by interpolating from representative correction values stored in cells of the LUT that surround an address corresponding to the combination of input signal levels. When the cells that surround the address include a pair of adjacent cells arranged along both sides of a diagonal line of the LUT, the interpolation circuit substitutes one of the representative correction values with a substituted representative correction value that indicates an opposite direction and a same amount of correction as indicated by the other one of the representative correction values stored in the adjacent cells, and then generates the conversion data.
