An image recording method for an image recording medium is used in an image display apparatus that changes an image on a light valve and changes quantity of light which is incident on the light valve via a light control element according to an input image signal. The image recording method includes accommodating a range of brightness information which an object to be imaged indicates, in an entire range of brightness information which an image recording apparatus can record in the image recording medium; and recording a light-control control signal for controlling the light control element when an image signal is recorded on the image recording medium. The light control element is generated on the basis of the range of the brightness information uniformly expanded, in synchronization with the image signal.

In the moving image display device of the invention, a synthesis circuit inputs signals representing specified values of pixel rate factors R2 and R3 from a pixel rate factor specification circuit, while inputting overscanned frame image data D1 in the units of pixels from a 1st latch circuit. The synthesis circuit extracts a preset number of pixels corresponding to the specified value of the pixel rate factor R2 from a prior frame image, while extracting a preset number of pixels corresponding to the specified value of the pixel rate factor R3 from a latter frame image. The positions of pixels to be extracted from the latter frame image are complementary to the positions of pixels to be extracted from the prior frame image. The synthesis circuit combines the extracted pixels of the prior frame image with the extracted pixels of the latter frame image by a logical OR operation to generate intermediate frame image data D2. This technique of the invention is significantly simpler than the prior art technique but still effectively prevents flicker in a moving image to ensure smooth display of the moving image.

An object of the present invention is to provide a liquid crystal device which can suppress cross-talk and can maintain uniformity of the display quality within the screen, and for which problems such as insufficient writing do not occur. In a liquid crystal light valve of the invention, an image signal for which the polarity is inverted for each one horizontal period, is supplied to each data line, and for each horizontal period plural pulse signals which each rise at a different timing, are supplied to each of plural scanning lines while skipping one part of the scanning lines. Moreover driving is such that in any one horizontal period, plural scanning lines, to which is supplied a pulse signal rising at a timing corresponding to an application period of a positive polarity potential, are adjacent to each other, and plural scanning lines, to which is supplied a pulse signal rising at a timing corresponding to an application period of a negative polarity potential, are adjacent to each other.

Exemplary embodiments of the present invention provide an image rearranging unit that synthesizes an input image with a delayed signal thereof and arranges an image having a horizontal frequency n times larger than a horizontal frequency of the input image in a signal arrangement according to scanning of a scanning driver, to thereby obtain a write image. The scanning driver selects n scanning lines spaced apart from each other in one horizontal period of the input image and drives pixels with image signals having the same polarity between most adjacent lines. Thus, a horizontal electric field can be reduced or prevented by a plane inversion driving. Adjacent to a blanking period having a polarity, a write operation by an image signal having an opposite polarity is performed. In this case, however, a low level blanking signal, for example, is also used, instead of a blanking signal. Thus, in the blanking period, the write operation of the image signal is not affected by a high black level ghost. As a result, display quality can be reduced or prevented from deteriorating.
