The restricted area is held by two lines each of which passes the origin and represents a boundary between one of the two color components and an area representing a color component made by mixing the one color component and another color component.

Abstract: An image display apparatus is provided that avoids discontinuity in a high luminance and gradation range and is capable of displaying gradations where differences in sense of luminance change at equal intervals from an intermediate gradation range to the maximum value of the gradations. A gradation/light emission luminance converter 104 converts the gradation of an input image into data corresponding to a luminance to be displayed by a video light emitter 107 using predetermined conversion characteristics. In an intermediate gradation range, the common logarithms of the luminances to be displayed by the video light emitter 107 have a proportional relation to the gradations. In the high luminance and gradation range, the relation gradually deviates from the proportional relation; the nearer the gradation approaches the maximum value thereof, the larger the variation quantity of the common logarithm of the luminance to be assigned to an increment of the gradations becomes.
