    摘要: A projection display device includes: an aperture part which narrows light traveling toward an imager; a control part which controls the aperture part; a detection part which detects brightness of an image to be projected; and a determination part which determines whether the image is a still image or a moving image. In this arrangement, the control part operates the aperture part so as to narrow the light when the brightness of the image detected by the detection part is darker than predetermined brightness, and operates the aperture part so as to further narrow the light when the brightness of the image detected by the detection part becomes darker than the predetermined brightness. In addition, the control part sets the predetermined brightness for operating the aperture part so as to be darker when the image is the still image than when the image is the moving image.

    摘要: A gamma correction device for a liquid crystal display device including LCD panels. The gamma correction device includes a storage device for storing gamma correction data corresponding to chiral directions of LCD panels. A chiral direction data acquisition circuit acquires chirality data on the chiral direction of a LCD panel arranged in the liquid crystal display device. A control circuit sets a gamma correction datum adapted to the chiral directions of the LCD panel arranged in the liquid crystal display device selectively from the stored gamma correction data based on the acquired chirality data. A gamma correction circuit performs a gamma correction process on image signals provided to the LCD panel using the set gamma correction datum.
