Abstract
An image processing apparatus processes input pixel data and outputs the processed pixel data as output pixel data. The image processing apparatus includes an input reliability calculation section for calculating an input reliability indicating the reliability of the input pixel data, an output reliability calculation section for calculating an output reliability indicating the reliability of the output pixel data, a motion-amount detecting section for detecting the amount of the motion of the input pixel data, a compensation section for compensating the output reliability according to the amount of the motion, and a processing section for processing the input pixel data according to the input reliability and the compensated output reliability and for outputting the output pixel data.

21. A noise-amount estimate apparatus for estimating an amount of noise in data, comprising:
-
input means for receiving input data of a present time interval;
first latching means for latching the input data of the present time interval;
second latching means for latching an immediate previous input data from an immediate previous time interval, wherein the immediate previous input data is received from the first latching means;
noise-amount calculation means for calculating the amount of noise in the present time interval as a function of a calculated variance of the input data stored in the first latching means and the second latching means, outputting means for outputting the calculated amount of noise as the amount of noise in the data. - View Dependent Claims (22)
