摘要： In accordance with the invention, signal electrode voltages are generated based on a plurality of scanning pattern sets. A storage circuit stores a display pattern and scanning patterns belonging to a first scanning pattern set PA in association with selection data Ds. A data control unit inverts display data d based on an inversion control signal CTL to generate converted display data d′. The inversion control signal CTL becomes active in association with each element at which the first scanning pattern set differs from a second scanning pattern set. First to third data registers generate a display pattern based on the converted display data d′.

摘要： An image signal processing circuit (102) includes a phase-expansion circuit (103), a digital polarity-inversion circuit (104), first to sixth D/A converters (111 to 116), and first to sixth operational amplifiers (151 to 156). The resistance value of the first to sixth amplitude adjusting resistors (121 to 126) which cause the output amplitude of an analog signal output from the first to sixth D/A converters (111 to 116) to be fixed is adjusted by laser trimming. First to sixth gain setting resistors (161 to 166) are connected to the first to sixth operational amplifiers (151 to 156). The first gain setting resistor (161) includes a first resistor (131) and a second resistor (141), and the gain of the operational amplifier (151) is set by the resistance ratio (R2/R1) thereof. In order that this resistance ratio (R2/R1) is fixed for each set, the first resistor (131) and the second resistor (141) are formed on the same substrate by undergoing the same manufacturing process. As a result, there is no need to use the first and second resistors (131, 141) for variable resistors.

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： Aspects of the invention can provide an image processing circuit for gray scale correction, an image display apparatus, and an image processing method that allow reduction in the storage capacity needed for storing correction characteristics data without increasing clock rate in relation to interpolation processing of correction characteristics. A exemplary image processing circuit according to the invention can be applied, for example, to color correction or gamma correction of color image data. Gray scale correction characteristics data for a number of gray scale levels that is less than the number of gray scale levels of input image data can be stored in first and second lookup table storing units. Considering a gray scale value of a pixel that is being considered for gray scale correction processing as an input gray scale value, the first and second lookup-table storing units are referred to, obtaining an output gray scale value corresponding to the input gray scale value and an output gray scale value corresponding to an adjacent input gray scale value. An adjacent gray scale value refers to a gray scale value that is higher by one or lower by one than another input gray scale value. Then, output gray scale values between these two adjacent output gray scale values can be calculated by linear interpolation, obtaining output values for all input gray scale values. Subsequently, gray scale correction can be performed for each pixel of input image data, outputting corrected image data.

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.
