Abstract
An image processing system is disclosed that includes a buffer unit configured to store a predetermined pixel and peripheral pixels neighboring the predetermined pixel in image data in a first direction and a second direction perpendicular to the first direction; and a first edge-detecting circuit configured to calculate a maximum value and a minimum value of a set of pixels selected from the peripheral pixels that have the same color as the predetermined pixel to calculate a difference value between the maximum value and the minimum value.
