Abstract: An object of the present invention is to provide a material for organic EL elements, the material being excellent in hole injecting/transporting performance, electron-blocking capability, stability in the form of a thin film, and durability. Another object of the present invention is to provide an organic EL element having high efficiency, a low driving voltage, and a long lifespan, by combining the aforementioned material with various materials for organic EL elements, the materials being excellent in hole/electron injecting/transporting performance, electron-blocking capability, stability in the form of a thin film, and durability, such that the properties of the individual materials can be effectively exhibited.

Abstract: A method for processing a high dynamic range (HDR) image for printing. Tone mapping is first applied to the input image to map the colors from the original color space to an extended RGB space without scaling or clipping of colors. The colors are then converted to a device-independent color space such as Jab, and scaled (normalized) in that space. Then, image-based gamut mapping is performed in the Jab space to map the gamut of the image to the gamut of the destination device. The colors are then converted to the color space of the destination device (e.g. printer) and outputted.

Abstract: This invention provides an automatic color converter for on-screen signals including a color television displaying the color signals of image signals provided from a color demodulation integrated circuit on a cathode-ray tube through a cathode-ray tube driver. The converter uses a level detector for detecting the level of the original color signals R, G and B for image signals provided through a color demodulation IC, a decoder for decoding eight selections according to the detected level state detected through the level detector, a stage for combining the output of the decoder using OR gates, and an on-screen driver for selecting the color signals R, G or B provided from the color demodulation integrated circuit in accordance with the input signal of the combination means and applying the selected signals to the cathode-ray tube.
