摘要： A method for controlling characteristics of an electronic device based on ambient light levels is provided. In one embodiment, the method includes receiving light at an ambient light sensor of a device and measuring components, such as color components, of the visible light. The component levels may be weighted differently by factors that vary based on the intensity of the light received by the ambient light sensor. Also, the brightness level of a light source in the device or color output of the device may be controlled based on the weighted component levels. Additional methods, systems, and devices relating to control of an electronic device based on sensed ambient light are also disclosed.

摘要： One embodiment of the present invention provides a system that uses a sound sensor to adjust the audio output of a device. During operation, the system uses the sound sensor to determine an ambient sound level for the environment in the proximity of the device. The system then adjusts a volume setting for the device adaptively based on the determined ambient sound level. Adaptively adjusting the volume setting allows the device to adapt to its audio environment and ameliorates potentially-disruptive audio outputs.

摘要： A method for reading a meter includes (1) capturing a first image of digits displayed by the meter, (2) roughly locating the digits by correlating the entire first image against symbols, (3) precisely locating the digits by correlating the digits against the symbols, which are now rotated, resized, and repositioned to maximize correlation, (4) determining and storing nominal centers of the digits in a nonvolatile memory. The method further includes (5) capturing a second image of the digits, (6) locating regions of interest in the second image according to the nominal centers, (7) determining vertical positions of full digits (or partial digits) in the regions of interest, (8) aligning symbols (or partial symbols) and the full digits (or the partial digits) according to the vertical position, and (9) correlating the symbol and the full digits (or the partial symbols and the partial digits).

摘要： A dual purpose ambient light sensor. More particularly, an ambient light sensor may be provided on an electronic device to aid in controlling the brightness of the illuminators of the device. The ambient light sensor may be mounted in such a way as to detect ambient light when the electronic device is opened or closed so that the device may control the brightness of the illuminators of the device, whether the illuminators are mounted on the outer or inner shell of the device. Further, when the display is closed, the sensitivity of the ambient light sensor may be adjusted appropriately to account for the lesser amount of light that may reach the sensor. Finally, a spacer or light pipe may be provided to allow ambient light to reach the sensor to provide an accurate ambient light reading when the device is in the closed position.
