  • Patent number: 8301024
    Abstract: A camera flash comprises a light guide arranged to extract light at least through one surface; and one or more light sources arranged, in use, to emit light into the lightguide. Each light source is an LED or a laser diode. The camera flash is connectable, in use, to drive circuitry, the drive circuitry being for driving the light source(s) to emit a pulse of light. The waveguide spreads out the light from the light source(s), so that a flash of light from the camera flash does not present a safety risk, while minimizing loss of the light from the light source(s). The camera flash can thus provide a high overall optical output, spread over an extended area (as defined by the waveguide). The lightguide may for example be disposed around a camera module of a mobile telephone camera.

  • Patent number: 8131518
    Abstract: To provide a functional spectral filter through which, it is possible for an observer wearing the functional spectral filter to change his or her color sensitivity (ease of color distinction), and which is for designing a color scheme easy to be distinguished for a color deficient observer by using the filter. A functional spectral filter including a multilayer is formed in accordance with a thin film design (an optimization method) determined by use of a color vision theory so as to make color sensitivity into a desired pattern. With respect to combinations that two colors among a plurality of specified colors are combined, color differences in the respective combinations are made close to a color difference given in advance. Alternatively, with respect to specified combinations, the color differences are made small or the color differences are made large.
