A color display device for displaying an n-primary color image, wherein n is greater than three, the device including an array of sub-pixel (801) configured to have at least one repeating unit having one sub-pixel representing each of the n primary colors, wherein repeating unit (906) is configured to optimize at least one attribute of the n-primary color image.

An LED signal lamp (100) comprises: a housing (102), at least one LED excitation source (108) operable to emit excitation radiation of a first wavelength range (blue light), at least one phosphor material (114) for converting at least a part of the excitation radiation to radiation of a second wavelength range and a substantially transparent cover (104) provided on the housing opening. In one arrangement the excitation source (LED chip) incorporates the phosphor material. Alternatively, the phosphor can be provided remote to the excitation source such as for example on a transparent substrate which is disposed between the excitation source and transparent cover. In other arrangements, the phosphor is provided on the transparent cover or other optical components as a layer on a surface of the cover or incorporated within the cover / optical component material.

A converting system and a converting method of three-color data to four-color data are provided. The converting system includes: a first calculating part configured to calculate a saturation value and a luminance enhancement coefficient according to inputted RGB values, a second calculating part configured to calculate luminance-enhanced RGB values according to the luminance enhancement coefficient and the inputted RGB values, a white determining part configured to use a minimum value of the luminance-enhanced RGB values as an outputted W value, and a three-color determining part configured to calculate outputted RGB values according to the luminance-enhanced RGB values and the outputted W value. The invention can obtain optimal outputted W values for different inputted RGB values and maximally increase the transmittance of the display apparatus. Accordingly, the display apparatus can increase the saturation of display image while enhance the transmittance.

A system and method for automatically altering an image having pixels is disclosed. An image is segmented into regions and various features of the regions are extracted and used to calculate a confidence factor, or belief value, that a particular region is a main subject of the image. The belief values are assembled into a belief map that is used to define how pixel values are to be altered. Various color and appearance values of the pixel are altered in a predetermined way to emphasize the main subject of the image. The emphasis is applied in a binary fashion or as in a gradient of values. Either the main subject can be emphasized, or the secondary or background subjects can be de-emphasized. The system can be implement on a variety of computer systems.
