Claim One:
1. A driving device of a display apparatus comprising: a data line; n (n is a positive integer greater than or equal to 3) scanning lines that each intersect the data line; n pixels, each of the n pixels corresponding to a separate scanning line of the n scanning lines, each of the n pixels disposed to correspond to the intersection of the data line and the corresponding scanning line, wherein, the driving device includes a calculation unit which calculates a correction value to correct a gradation value of a correction target pixel among the n pixels; and a correction unit which corrects the gradation value of the correction target pixel on the basis of the correction value, and wherein the calculation unit performs a first calculation for each gradation value of m (m is a positive integer smaller than or equal to n) pixels among the n pixels in a first range, and performs a second calculation that is different from the first calculation for each gradation value of n−m (n minus m) pixels among the n pixels in a second range that is different from the first range, wherein the first calculation multiplies by a first coefficient, the second calculation multiplies by a second coefficient that is different from the first coefficient, the calculation unit performs one of the first calculation and the second calculation for each of a first group of pixels of the n pixels that belong to a first frame, the calculation unit performs one of the first calculation and the second calculation for each of a second group of pixels of the n pixels that belong to a second frame that either precedes or follows the first frame, the second group of pixels comprising different pixels than the first group of pixels, and the calculation unit calculates the correction value of the correction target pixel based on each of the first calculations and the second calculations for both the first group of pixels and the second group of pixels.
