Zusammenfassung:PROBLEM TO BE SOLVED: To provide an image processor capable of improving picture quality improving an effect by widening the frequency range of enhancement processing, and also performing two-dimensional enhancement processing for an image signal by simple circuit constitution. SOLUTION: A vertical low-pass filter (160) and a vertical high-pass filter (100), and horizontal high-pass filters (110) and (170) and a horizontal low-pass filter (120) are provided as enhancers, and high-frequency components and low-frequency components are extracted vertically and horizontally. The cutoff frequency of the first horizontal filter (110) is set to ≤1/8 time as high as a sampling frequency and a roll-off rate is set to about 1.0. COPYRIGHT: (C)2007,JPO&INPIT
