Abstract
Abstract PURPOSE: To measure a noise component in an image signal. CONSTITUTION: A mobile signal (L) is formed 3 by taking the difference between an image signal that does not delay and an image signal that delays 2 and continuously forming an absolute value. In this method, first, the amplitude maximum value (M) of the mobile signal is decided 4 in a search window and then, the minimum value (O) that corresponds to the peak value of noise is measured 6 from the maximum value of plural search windows.
