A structure of multi-wavelength light emitting device comprises multi-stacked active layer structure. Each stacked layer comprises lower energy bandgap well 4 and higher energy bandgap barrier layer 3 wherein at least one stacked layer in the device contains nanoparticles. As a result, the emitting wavelengths of the multi-stacked active layer structure consist parts (or all) of the emitting wavelengths come from the stack layers containing nanoparticles, and parts (or all) of the emitting wavelengths come from the stack layers not containing nanoparticles. In another embodiment, parts (or all) of the emitting wavelengths of the multi-stacked active layer structure can be also used to trigger one or more phosphorescences from the phosphors, thus the emitting wavelengths of such a phosphors converted light emitting device may come partially from the multi-stacked active layer itself and partially (or all) from the phosphors.

In a displaying method for use in an image display, an original gray scale is divided into a higher gray scale and a lower gray scale. Further, the color subpixels are divided into two groups corresponding to the higher and lower gray scales, respectively. The gray scale to be expressed by each subpixel is calibrated by weighing the original higher or lower gray scale for the pixel and the adjacent pixels and summing up the results. The color shift problem due to different visual angles can therefore be solved.

A scalable video bitstream may have an H.264 / AVC compatible base layer and a scalable enhancement layer, where scalability refers to color bit depth. The H.264 / AVC scalability extension SVC provides also other types of scalability, e.g. spatial scalability where the number of pixels in BL and EL are different. According to the invention, BL information is upsampled in two logical steps, one being texture upsampling and the other being bit depth upsampling. Texture upsampling is a process that increases the number of pixels, and bit depth upsampling is a process that increases the number of values that each pixel can have, corresponding to the pixels color intensity. The upsampled BL data are used to predict the collocated EL. The BL information is upsampled at the encoder side and in the same manner at the decoder side, wherein the upsampling refers to spatial and bit depth characteristics.

The invention is directed to a method and a device for providing higher performance imaging capture using a novel pattern of a color filter array that enables one to achieve higher sampling rate for luminance than for chrominance. A majority of the elements in the CFA are neutral elements. Gray scale images with high spatial resolution and high light sensitivity can be acquired from image samplings at these neutral elements. The remaining elements of the CFA are color filtered ones. Color elements cluster to form a repeating block pattern. Color images with low spatial resolution but low color artifacts can be acquired from image samplings at these color filter elements. The color images are transformed into a luminance-chrominance color space, and the luminance components are replaced with the gray scale images to regain high spatial resolution.

An intelligent color gamut management method. The intelligent color gamut management method performs a saturation mapping and a luminance mapping separately according to a characteristic of a target device, thereby enabling the target device to represent a natural color image.

Since the color gamut boundary can be easily obtained, a memory capacity can be saved a freedom of algorithm can be increased.
