摘要： Provided is a filter coefficient calculation method that calculates filter functions, each having (2n+1) rows and (2n+1) columns (n is an integer), the method including calculating a first filter function in accordance with a set value that is externally input, calculating an error between a total sum of values included in the first filter function and an ideal value of the total sum, supplying an odd error included in the error to a first origin coefficient that is located at a center of the first filter function as a first correction value if the error is an odd number, and supplying an even error to one of the first origin coefficient and a coefficient pair that is located symmetrically with respect to a point of the first origin coefficient as a second correction value, the even error being the error except the odd error.
