    摘要： 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.

    摘要： A system and method for reducing power consumption in an electronic device by controlling the transition of the electronic device from a sleep mode to a full power mode. The electronic device comprises a main processor a touch-sensitive overlay, and an overlay controller. A sequence of touch inputs on the touch-sensitive overlay are detected and captured using the overlay controller while the main processor is in the sleep mode. A subset of the sequence of touch inputs is processed using the overlay controller to determine that the sequence of touch inputs corresponds to a coarse model of a pre-determined wake-up gesture prior to transitioning the electronic device from the sleep mode to the full power mode.

    摘要： 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.

    摘要： A method and apparatus for maintaining a maximum sustained flash current over the whole length of a flash using a programmable current drive in a handheld portable device powered by a battery. The method involves measuring the battery voltage before and after a flash is initiated and calculating the equivalent series resistance (ESR) of the battery. The calculated ESR is then used to adjust the flash current. The process may be repeated to correct for errors in the flash current.

    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.
