An energy saving device for an LED lamp mounted to an existing fixture for a fluorescent lamp where the ballast is removed or bypassed. The LEDs are positioned within a tube and electrical power is delivered from a power source to the LEDs. The LED lamp includes means for controlling the delivery of the electrical power from the power source to the LEDs, wherein the use of electrical power can be reduced or eliminated automatically during periods of non-use. Such means for controlling includes means for detecting the level of daylight in the illumination area of said least one LED, in particular a light level photosensor, and means for transmitting to the means for controlling relating to the detected level of daylight from the photosensor. The photosensor can be used in operative association with an on-off switch in power connection to the LEDs, a timer, or with a computer or logic gate array in operative association with a switch, timer, or dimmer that regulates the power to the LEDs. An occupancy sensor that detects motion or a person in the illumination area of the LEDs can be also be used in association with the photosensor and the computer, switch, timer, or dimmer, or in solo operation by itself. Two or more such LED lamps with a computer or logic gate array used with at least one of the lamps can be in network communication with at least one photosensor and / or at least one occupancy sensor to control the power to all the LEDs.

Provided is an image processing method and a apparatus of converting a color input image or a partial region thereof in accordance with a color gamut of a color image output apparatus is provided. The method and apparatus is characterized in that only the region requiring color gamut compression can be put to color gamut compression depending on the distribution of an input image, that the direction of the color gamut compression can be controlled continuously for each of the regions; the amount of the color gamut compression can be controlled continuously including clipping, that when color gamut compression is conducted by a color converter of a multi-dimensional DLUT interpolating calculation type, an excessively unnecessary color gamut compression can be avoided particularly upon clipping, and that there is enabled correction for visual bending in iso-hue lines caused by distortion of a color space in each of the regions of the color space.

In a method of correcting a desired color of a pixel to be displayed in an optical see-through display, a binned-display profile of prescribed colors arranged to be rendered by the display include background colors added to it so that the desired color can be matched to a closest one of the resulting predicted color profile of colors which are predicted to be perceived by a user. The display is then instructed to display the prescribed color which corresponds with the closest matching predicted color such that an observer substantially perceives the desired color. Typically the desired color is only compared to a subset of the predicted colors for efficiency. Additional corrections may take place to improve contrast of graphical content compared to the background in some instance.

A method for color correction is provided. In this method, a plurality of groups of gray levels and luminance of light source of display device are respectively selected by color measurement system. The selected data of each color light are respectively calculated to obtain fitting functions which can fit the gray level data of each interval. The fitting luminance of the gray levels in interval is obtained by the fitting function and formed into a lookup table. Then in order to correspond a gamma curve of normalized gray data of image to a predetermined target curve, the two gamma curves are first taken to logarithmic calculation and the modified gray signals are obtained from the lookup table, then the modified gray signals are transmitted out for providing the display device to express the gray distribution state. The method for color correction is applicable to various display devices, especially liquid crystal display device.

A method for driving a display is disclosed. According to the driving method, a display panel is divided into a plurality of bright regions and a plurality of dark regions, wherein the dark regions and the bright regions are alternately arranged so that the bright regions within the display panel are not adjacent to each other. Next, a full-color frame is divided into four sub-frames, wherein the sub-frames are matched with the four color-orders one by one. In this way, the display randomly displays the sub-frames in a frame period.

A display device includes an ultraviolet light source, a color light source, and a filter selectively hit by their lights. The filter has a first area part for displaying the first display contents excluding an overlapped parts when the ultraviolet light is emitted, a second area part for the second display contents excluding the overlapped parts when the color light is emitted, and a third display part for displaying the overlapped parts when one of the ultraviolet and color light is emitted. The first area part blocks the color light and produces visible light when the ultraviolet light hits the first area part, the second area part allows the ultraviolet and color lights to pass therethrough, and the third area part allows the ultraviolet and color lights to pass therethrough and produces the visible light when the ultraviolet light hits the third area part.
