  • Publication number: 20130293597
    Abstract: A technology for reducing the so-called “phosphor burn-in” phenomenon where the variation of luminance arises by reducing display luminance of a certain pixel caused by deterioration in a display apparatus constituted by an organic electro luminescence element is provided. In the display apparatus, when displaying an image acquired by an image acquiring unit, luminance substantially same as average luminance of the acquired image is set to a non-display area where the image is not displayed.

  • Patent number: 8269799
    Abstract: An image signal processor includes a controller configured to generate a red output signal, a green output signal, a blue output signal and a fourth color output signal in accordance with image input signals. A fourth color light component enables to reproduce a color outside the range of a color reproducible by the red light component, the green light component and the blue light component. The controller generates the fourth color output signal on the basis of a reference signal corresponding to a color different from a complementary color of a color reproduced by the fourth color light component.

  • Publication number: 20100245780
    Abstract: A detection unit detects an entering object that will enter at least a projection space. When an entering object has been detected by a first detection unit, a controller initiates safety processing, the safety processing being milder than safety processing that is initiated when an error has occurred in the projection display apparatus itself. For example, when an entering object has been detected, the controller controls components of the projection display apparatus so as to switch to the projection of a black image and so as to maintain the state of the projection display apparatus, excluding the switching.
