  • Patent number: 8063873
    Abstract: The disclosure describes a system and method for adjusting a backlight for a display for an electronic device. In the method, the following steps are provided: identifying a highest brightness value of an image for generation on the display; determining whether there is sufficient brightness headroom for the image based on the highest brightness value. If the brightness headroom is sufficient, then the method adjusts the image to create an adjusted image where elements of the adjusted image are boosted in brightness from the image based on the brightness headroom; and generates the adjusted image on the display. Finally, the method adjusts a backlight level to a lower adjusted backlight level for the adjusted image based on the brightness headroom.

  • Patent number: 8010762
    Abstract: The invention relates to a system and method for controlling implementation of a command to a NAND memory device. The method comprises: monitoring an input/output (I/O) bus connected to the NAND memory device for an assertion of a write command for the NAND memory device. Upon detection of the write command, the method evaluates a destination address associated with the write command. If the destination address is not a restricted address for the NAND memory device, then the method allows the write command to modify the contents; and if the destination address is a restricted address for the NAND memory device, then the method prevents assertion of the write command on the contents.

  • 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.
