<p>An image picked up through a lens system (100) and a CCD (101) is converted at an A/D (102) into a digital signal and stored in a buffer (103). Output from the buffer (103) is inputted to an output section (106) through a noise reducing section (104), and a signal processing section (105). In the noise reducing section (104), low frequency components are generated at a low frequency component generating section and high frequency components are generated at a high frequency component generating section. A threshold is set for each similar direction of high frequency components at a threshold setting section. Furthermore, high frequency components are converted at a high frequency component converting section based on the thresholds thus set, and the low frequency components and the converted high frequency components are synthesized at a synthesizing section.</p> |
