A liquid crystal display device includes: a driver circuit portion; a pixel portion; a signal generation circuit for generating a control signal for driving the driver circuit portion and an image signal which is supplied to the pixel portion; a memory circuit; a comparison circuit for detecting a difference of image signals for a series of frame periods among image signals stored for respective frame periods in the memory circuit; a selection circuit which selects and outputs the image signals for the series of frame periods when the difference is detected in the comparison circuit; and a display control circuit which supplies the control signal and the image signals output from the selection circuit, to the driver circuit portion when the difference is detected in the comparison circuit, and stops supplying the control signal to the driver circuit portion when the difference is not detected in the comparison circuit.

An optical imaging system is provided comprising a first lens group having a positive refractive power; a second lens group having a negative refractive power; a third lens group having a positive or negative power; and a fourth lens group having a positive or negative power.

In order to provide an image processing system that can correct color non-uniformity due to deterioration with time in a more appropriate manner, a projector is provided with an image projection section which displays a calibration image; a sensing section which senses the displayed calibration image; an area detection section which detects an image display area based on sensing information, and also divides the image display area into a plurality of target areas; a brightness information generation section which generates brightness information which indicates an average brightness index value within each of the target areas that have been divided by the area detection section, based on the sensing information; a correction amount calculation section which calculates a correction amount for input-output characteristic data from each of the target areas, based on the brightness information; and a color non-uniformity correction section which corrects color non-uniformity of the image, based on input-output characteristic data that has been corrected based on the correction amount.

Emulsions, emulsifier, a method of use and a production process of said emulsions are presented in the present invention. The emulsion composed of a mixture of water and oils and additives sheared into small droplets using a low pressure, three shearing stage emulsifier. The oils used in the preparation of said emulsions are botanical oils and in most cases, edible oils.

A semiconductor device includes: an insulating base; a semiconductor element provided on the insulating base; a protector provided on the semiconductor element; and a frame provided on a periphery of the insulating base and surrounding the semiconductor element. A region inside the frame is filled with a sealing resin, and at least one groove is provided in an upper corner portion of the frame on the semiconductor element side of the frame.

An image-fixing method for heat-fixing a toner image, by feeding an transfer medium carrying the toner image between a heating unit heated by an induction-heating process and a pressurizing unit placed to press against the heating unit, wherein the electric resistivity at least of the outermost layer of the heating unit is 10−7 Ωm or more and less than 10−2 Ωm, and the toner image is formed by using a toner containing an amorphous resin having an ionic concentration in the range of 10−5 to 10−3 mole / g as the binder resin.

A phosphor layer is provided on a back glass substrate placed opposite a front glass substrate with a discharge space in between, and formed in a double-layer structure consisting of a first phosphor layer and a second phosphor layer having its surface covered by the first phosphor layer. The first phosphor layer is formed of materials that permit the passing-through of a xenon molecular beam but absorb a xenon resonance line in the vacuum ultraviolet light generated from a discharge gas by means of a discharge, and have a higher resistance to the resonance line than that of the second phosphor layer. The second phosphor layer is formed of materials that have, as compared with the first phosphor layer, a higher light-emission brightness based on the xenon molecular beam in the vacuum ultraviolet light generated from the discharge gas by means of the discharge.
