Abstract: It is intended to provide an effective value impedance simulation method and apparatus in which even when an external circuit is opened or short-circuited, no infinite current or voltage occurs, no instability occurs in a numerical analysis, and the probability that a physical apparatus is broken is low. An instantaneous value/effective value conversion section connects a resistor and an externally controllable current source in parallel, measures an instantaneous value current i that flows through the parallel connection of the resistor and the current source, and converts the measured instantaneous value current i into an effective value current I. Another instantaneous value/effective value conversion section measures an instantaneous value voltage v that is applied to the parallel connection of the resistor and the current source, and converts the measured instantaneous value voltage v into an effective value voltage V.

Abstract: An image processing apparatus and method and a recording medium therefor control the occurrence of a change in a hue. The histogram of a luminance signal Y is generated in a first step S1. In a second step S2, the histograms of the luminance signals Y are accumulated to generate a cumulative histogram, and the cumulative histogram is subjected to logarithmic approximation thereby to generate a lookup table (LUT) for correcting luminance signals. In a third step S3, a color-difference signal correction parameter LUT is generated by referring to the LUT for correcting luminance signals. In a fourth step S4, an input luminance signal Y is applied to the LUT for correcting luminance signals thereby to acquire a corrected luminance signal Y0. In a fifth step S5, the input luminance signal Y is applied to a color-difference signal correction parameter LUT so as to acquire a correction parameter k.
