摘要： An aspect of the invention provides an image display apparatus that displays a plurality of input pixels which form input image data on a display section. In that case, each input pixel can be displayed in such a manner that display pixels having gradation values differing from the gradation value of the input pixel are combined. For example, when a pixel having a particular gradation value exists as an input pixel, the pixel is not displayed on the display section as it is being kept at the gradation value, but instead, is displayed in such a manner that a plurality of display pixels having gradation values differing from the gradation value of the input pixel are combined. As a result, the same gradation value is not displayed continuously. Therefore, this results in that the occurrence of crosstalk, which is problematical particularly in a TFD liquid-crystal panel, is reduced. Accordingly, the invention can remove crosstalk which is likely to occur in a TFD liquid-crystal panel by controlling the gradation level of a display image.

摘要： As a polarization beam separating device constituting a projection device, a thin-film multilayer film (reflective polarizer) is used. The thin-film multilayer film is composed of a plurality of alternately stacked layers including layers having a refractive index in a predetermined direction and a refractive index in a direction perpendicular to the predetermined direction, the refractive indices being almost equal to each other, and layers having different refractive indices in a predetermined direction and in a direction perpendicular to the predetermined direction. The use of the reflective polarizer makes it possible to reflect linearly polarized light polarized in a first direction and to transmit linearly polarized light polarized in a second direction, which is perpendicular to the first direction, with respect to light of almost all wavelengths in the visible region. As a result, the contrast of an image to be projected can be improved.

摘要： The invention provides an easy and simple method of converting the resolution of image data, which is capable of generating the high-resolution image data without incongruity, does not make a circuit in the display device complicated and does not increase the power consumption. This invention can include a portable terminal device, such as a mobile telephone or a PDA, that processes and displays image data transmitted from the outside. Image data with a plurality of grayscales can be displayed by controlling the display state of each pixel in a display unit in accordance with grayscale control pulses corresponding to the number of grayscales. For example, when a 64 grayscale display is performed, a grayscale level is defined using sixty four grayscale control pulses. Thus, it is possible to emit light from pixels in the display unit by sixty four grayscale levels. Further, the resolution converting device can generate pseudo-high-resolution image data obtained by increasing the number of pixels of original image data by n multiplication and by reducing the number of grayscales of the original image data to 1/n. When displaying the pseudo-high-resolution image data, the number of grayscale control pulses is changed to 1/n by a halftone controller. That is, in the pseudo-high-resolution image data, the number of grayscales is 1/n. Therefore, the number of grayscale control pulses used for halftone display may be 1/n in accordance with the number of grayscales. Therefore, the low-resolution image data can be displayed without incongruity by converting the resolution, also, it is possible to reduce power consumption of the display unit by the reduced amount of the number of grayscale levels pulses.

摘要： To provide a color matching system which enables reliably color-matched image data to be displayed on a display device without effort to perform color matching on applications. A color matching system is mounted on, for example, an image display device, and performs color conversion adapted to color characteristics of a display device. A graphics interface, such as a graphics device interface (GDI), generates image creating commands for image data generated according to the operation of an application, and the display image data is generated based on the image creating commands. The display image data is supplied to the display device after the display image data has been subjected to the color conversion by the color management module and the color space adjustment has been performed based on a color attribute file representing the color characteristics of the display device. With this configuration, the display image data adapted to the color reproducibility of the display device is displayed on the display device. Since the color conversion process for color matching is performed not by an application side but instead by the color management at a hardware-dependent portion, such as an OS, a proper color matching is achieved without requiring any intervention from the application side.

摘要： Aspects of the invention provide a color matching profile generating device that, in an apparatus having an input device and an output device, performs a color matching for the input device and the output device and reproduces favorable colors without depending on color characteristics of the devices. The color matching profile generating device can use an input device profile and an output device profile, in addition to a color conversion profile which defines color conversion characteristics in an absolute color space and generates a color matching profile for the input device and the output device. Since the color conversion profile defines the color conversion characteristics in the absolute color space, color conversion can be performed to image data obtained from the input device without depending on characteristics of the input device. Accordingly, by performing a color matching process with the generated color conversion profile, image data can be output with color characteristics determined in the absolute color space, irregardless of characteristics of the output device.
