    摘要: A liquid crystal display device for carrying out a 3D display by a frame sequential method as well as a 2D display includes: a digital γ correction section (21) for changing an input gray level to a gamma characteristic corresponding to either the 2D display or the 3D display in accordance with a preset analog gamma value; an overdrive circuit (23) for finding, in accordance with a parameter set according to the gamma characteristic thus corrected by the digital γ correction section (21), an overdrive value corresponding to the input gray level; and an analog γ correction section (22) for finding a voltage value to be applied to liquid crystal by correcting the overdrive value found by the overdrive circuit (23). In the digital γ correction section (21), an analog gamma value for the 3D display is set to be larger than an analog gamma value for the 2D display. This makes it possible to display a high-quality display with no crosstalk when carrying out a 3D display by a frame sequential method.

    摘要: A liquid crystal display device of the present invention includes: a liquid crystal panel (1) capable of switching between a 2D display and a 3D display; a digital γ correction section (21) for changing a gamma characteristic of a video signal supplied to the liquid crystal panel (1); a backlight (2) for backlighting the liquid crystal panel (1), which backlight includes an LED serving as a light source; and a backlight driving section (13) for controlling driving of the backlight (2). When the 3D display is carried out on the liquid crystal panel (1), the backlight drive control section (13) controls the driving of the backlight such that luminance of the LED is higher than that for the 2D display, and the digital γ correction section (21) changes a gamma characteristic of a video signal such that (i) luminance on a low gray level side is lower than that for the 2D display and (ii) luminance on a high gray level side is higher than that for the 2D display. This makes it possible to increase luminance perceived by a user without increasing the number of LEDs.

    摘要: Disclosed is an angular rate detection apparatus which provides a stable output with high detection accuracy regardless of a fluctuation of a reference voltage accompanying a fluctuation of a power supply voltage. The angular rate detection apparatus includes at least a gyro sensor detection circuit connected to an oscillator, an A/D converter, a digital calculation device, and a reference voltage generation circuit. The gyro sensor detection circuit drives the oscillator, and detects an angular rate acting on the oscillator and outputs an analog detection signal. The A/D converter converts the output analog detection signal into a digital signal. The digital calculation device carries out a calculation based on the converted digital signal. The reference voltage generation circuit supplies a common reference voltage generation circuit supplies a common reference voltage to the gyro sensor detection circuit and the A/D converter.
