  • Patent number: 7646448
    Abstract: A method for providing a hot spot filter for a light guide is provided by taking an image of the light output pattern of an illuminated light guide. The hot spot filter may be a film, a layer, or an additional liquid crystal display dedicated to attenuating bright spots from the light guide. The hot spot filter may be incorporated into the image display by adjusting the grey scale of individual pixels to provide sufficient compensation.

  • Publication number: 20090219244
    Abstract: The disclosure relates to a system and method for determining pixel intensity values (luma values) for an image being displayed on a display of an electronic device, then adjusting the pixel intensity and the backlight level for the image that is output to a liquid crystal display (LCD). The system comprises: a display for displaying an image to be displayed on the device; an image adjustment module to identify the pixel intensity values of the image, to determine new pixel intensity values for the image based in part on the original pixel intensity values, to provide the (adjusted) image at the new pixel intensity values to the display and to determine a backlight level for the image at the new pixel intensity values. The system further comprises a backlight system to provide a backlight for the adjusted image at the adjusted backlight level.

  • Publication number: 20090130929
    Abstract: A water cooled fuel reservoir is provided for a carbureted engine. Water is drawn by a pump from a body of water and caused to flow to a water jacket surrounding a fuel reservoir of the carburetor. The fuel reservoir, or float bowl, stores a quantity of liquid fuel which is cooled by thermal contact with the water in a water jacket of the water reservoir.

  • Publication number: 20080180544
    Abstract: A method and an apparatus enabling use of a light source emitting a light of changing intensity and changing spectrum as a flash with a camera module having a white-balance routine and an exposure routine, wherein an initial value representative of a color spectrum emitted by the light source is transmitted to the camera module, the light source is turned on, and the camera module is signaled to scan a plurality of images of the scene while the light source is turned on, allowing the white-balance and exposure algorithms to be employed with each image scanned to refine the first initial value to refine the degree of compensation employed in correcting a color and a light level in the last one of the images of the plurality of images scanned.

  • Publication number: 20080180545
    Abstract: A method and an apparatus enabling use of a light source emitting a spectrum of light not following characteristics of a blackbody source of light with a camera module programmed for use with light sources following characteristics of blackbody sources of light, wherein a white-balance patch is transmitted to the camera module to cause the camera module to accept color coordinates representing a point on a chromaticity chart that partly defines a region of color coordinates on the chromaticity chart into which color coordinates of the light source fall and to which color coordinates of a reference white color derived by a white-balance routine of the camera module are constrained.

  • Publication number: 20080181596
    Abstract: An improved handheld electronic device and camera apparatus upon which can be executed an improved method enable a modular camera to be used in conjunction with a flash. In one implementation, compensation parameters that are intended for use in a non-flash situation are overwritten with compensation parameters that are configured to compensate for the combined effects of the camera and the flash and are used by an embedded compensation routine executed on the camera. In another implementation, an image signal is processed by the embedded compensation routine using the original compensation parameters, but if it is determined that the image signal is a flash image signal, the image signal is further processed by the embedded compensation routine employing an additional set of parameters which compensate the image signal for the effect of the flash.
