20120154458 | APPARATUS, DISPLAY DEVICE, PROGRAM AND METHOD THEREOF FOR PROCESSING IMAGE DATA FOR DISPLAY BY A DISPLAY PANEL - A method of processing image data for display by a display panel of a display device is provided. The method comprises receiving main image pixel data representing a main and side image pixel data representing a side image. In a first processing step, a mapping is performed of the pixel data to signals used to drive the display panel. The mapping is arranged to produce an average on-axis luminance which is dependent mainly on the main image pixel data and an average off-axis luminance which is dependent at least to some extent on the side image pixel data. In a second processing step, the received side image pixel data are processed to emphasise at least one feature of the side image which might otherwise be perceived by a viewer as being de-emphasised in the side image displayed off axis as a result of the first processing step. | 06-21-2012 |
20130015362 | FLUID PURIFICATION AND SENSOR SYSTEMAANM HOOPER; Stewart EdwardAACI OxfordAACO GBAAGP HOOPER; Stewart Edward Oxford GBAANM SMEETON; Tim MichaelAACI OxfordAACO GBAAGP SMEETON; Tim Michael Oxford GBAANM EVANS; AllanAACI OxfordAACO GBAAGP EVANS; Allan Oxford GB - A system and method are disclosed for the simultaneous optical disinfection and detection of biological particles in a flowing fluid, such as air or water, medium. A light source for irradiating the flowing medium is a dual wavelength laser element simultaneously emitting a visible laser beam and an ultraviolet laser beam. In particular, a laser diode may generate a first visible laser light beam, and a second ultraviolet laser light beam may be generated by passing the first laser light beam through a frequency doubling crystal. Optical detectors measure scattering, fluorescence and/or transmission of the laser light beams from the air or water medium to determine the presence of biological particles in real-time. | 01-17-2013 |
