An image taken via lens system (100) and CCD (101) is converted at A/D (102) into digital signals that are then stored in buffer (103). An output of buffer (103) is connected to output block (106) via noise reduction processing block (104), edge enhancement processing block (107) and signal processing block (105) in order. Noise reduction processing block (104) separated an image signal read out of buffer (103) into multiple frequency components. Transform processing is applied to the respective separated components that are then synthesized for noise reductions.
