IMAGE PROCESSING DECVCE AND IMAGE PROCESSING METHOD

摘要

An image processing device and an image processing method can perform interpolation that reduces overshoot and ringing on a step edge while maintaining high frequency components. The image processing device comprises: a vertical step edge area determination unit which determines a vertical step edge area of an image from an input image signal; a horizontal step edge area determination unit which determines a horizontal step edge area of the image from the input image signal; and an interpolation unit which performs interpolation based on the determination result of the vertical step edge area and the determination result of the horizontal step edge area.
