<p>Image signal processing method and apparatus having a first filter storage portion in which first filters are correlatively stored; a second filter storage portion in which second filters are correlatively stored; a first filter selection portion for selecting a first filter based on the power spectrum of the input image; a second filter selection portion for selecting a second filter based on the SIN (signal-to-noise ratio) of the input image; a third filter creation portion for creating a third filter by summing up the first and second filters; and a convolutional processing portion for convolving the input image using the created third filter.</p> |
