An image processing apparatus includes a storage unit storing an image and a processing unit performing image processing in each segment of the stored image to obtain a value of each pixel in a predetermined order using calculation results for peripheral pixels processed. At least one segment is a quadrangular area. Two sides of the quadrangular area extend from a first vertex of two opposite vertices of the area toward two of subsequent pixels after a first pixel at the first vertex so that the area includes the subsequent pixels whose values are obtained using a calculation result for the first pixel. The other two sides extend from a second vertex of the two vertices toward two of previous pixels before a second pixel at the second vertex so that the area includes the previous pixels for which a value of the second pixel is calculated using calculation results.
