    摘要: A display and a color correction method are disclosed. The display includes a panel and a backlight module. The color correction method includes steps of: (a) sensing a real-time backlight intensity of the backlight module; (b) increasing a backlight intensity of the backlight module when the real-time backlight intensity is different from a standard backlight intensity of the backlight module; (c) sensing a compensated backlight intensity of the backlight module and estimating a first real-time color information of the panel according to the compensated backlight intensity and a first panel color characteristic information, wherein the first panel color characteristic information corresponds to the penetration characteristics of the panel; and (d) estimating a first color gain compensation value for the panel according to the first real-time color information and compensating the colors displayed on the panel when the panel displaying an image according to the first color gain compensation value.

    摘要: Method and apparatus for presenting audio and visual information to an audience by streaming, broadcast, live and recording presentations including a generally planar display screen, a light source directing light towards the display screen, a video camera oriented towards the display screen so as to image a lecturer through the display screen and a filter disposed between the display screen and the video camera. In one embodiment the light source emits light in predominately blue wavelengths and the filter blocks at least 85% of light at approximately the same wavelengths. Visual information may then be beneficially written by a lecturer on the display screen using a fluorescent marker pen. In operation an image output of the video camera is reversed in left-to-right orientation so that visual image information written by a lecturer onto the display screen is reversed from an orientation of this information viewed through the display screen.

    摘要: The present invention relates to a display device comprising at least one display unit and an illumination device for illuminating an edge region of the at least one display unit. The invention further relates to a method for operating such a display device and to an entertainment device comprising such a display device. The display device according to the invention comprises, in addition to the at least one display unit and the illumination device, at least one determination means for determining a color information from an image block of the at least one display unit, and further comprises a color control means for controlling the color and/or color spectrum of the light emitted by the illumination device as a function of the color information. The color information can be obtained from the light which is actually emitted by the display unit in said image block, for which a light detection device having an observation region that is limited to the image block can be provided.
