    摘要: 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.

    摘要: 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.
