  • Publication number: 20110211089
    Abstract: An improved mobile electronic device and camera provide an improved auto white balance system where constraints can be imposed the correlated color temperature (CCT) that is employed by the auto white balance system. For instance, if a distance between a subject and the camera is determined to exceed a threshold for closeness, the CCT can be constrained so that it is above a preset CCT that corresponds with sunrise or sunset. Other distance thresholds and the content of an image, as well as the brightness of the image, can be further employed in determining the CCT to employ.

  • Patent number: 8009978
    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.

  • Patent number: 7978230
    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.

  • Patent number: 7978942
    Abstract: A system and method for compensating for non-uniform illumination from a light guide for a display in an electronics device is provided. The system comprises: a memory device storing a data representing a first compensation pattern for generation on the display to block light from a first portion of the light guide relative to light from a second portion of the light guide; a first module to incorporate the stored representation into an image to be displayed on the display; and a second module to generate the image with the stored representation for display on the display. In the system, when the first module generates the first compensation pattern on the display, the first compensation pattern aligns with the first and second portions to reduce an intensity of light from a light source passing through the first compensation pattern from the first portion relative to an intensity of light passing through the first compensation pattern from the second portion from the light source.

  • Patent number: 7777708
    Abstract: A method for reducing cross-talk on a liquid crystal display begins by receiving pixel data defining an image comprising a plurality of pixels; the received pixel data includes an intensity value associated with each pixel. The image is compressed by reducing the range of the intensity values of all the pixels in the image; the compressing step comprising arithmetically adjusting the intensity values of the pixels. Lines in the compressed image that are disposed to create cross-talk are identified. The image is then decompressed by applying a scale factor to the adjusted intensity value associated only with the pixels in the identified lines. The scale factor is selected such that a display image rendered on a liquid crystal display from the pixel data of the decompressed image has less cross-talk than a display image rendered on a liquid crystal display from the received pixel data.

  • Publication number: 20100156962
    Abstract: A field sequential liquid crystal display maintains its white colour point through compensation values to at least one colour light emitting diode that illuminates the display. The compensation values may be impedances to control the current or pulsing of the current source according to a pulse width modulation technique. A degradation curve may be used to calculate extrapolate the theoretical forward voltage of the light emitting diode. Additional complexity arises from the need for calculating uptime for multiple light emitting diodes of different colours. Brightness levels may also be factored in. Additional processing of a display element may be provided when a grey scale image is being generated.

  • Patent number: 7714832
    Abstract: A display screen is capable of having regions having different switching speeds as well as regions that are not switched. One region having a first switching speed may be for colour mode display and the other region having a second switching speed different from the first may be for monochrome mode display. Other regions may be off and not switched. In alternative versions, three or more switched regions may be established on a display screen. For example, a monochrome region may be nested inside a colour region, in which the colour region may be nested between off regions.
