Abstract
A method for interpolating an image signal using a slope correlation and the circuit thereof, in order to improve a picture quality by enhancing a vertical resolution. A slope correlation interpolation depending on a correlation degree between picture elements is performed for an image signal of a low frequency component, and a line interpolation is performed for an image signal of a high frequency component. Therefore, a vertical resolution is improved and hardware is decreased.
