An Apple patent (number 20120050307) for an ambient light sensing technique has appeared at the U.S. Patent & Trademark Office and shows that Apple is working on ways to control characteristics of electronic devices -- such as laptops and iPhones-- based on ambient light levels.
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. Peter H. Mahowald and Ulrich T. Barnhoefer are the inventors.
Here's Apple's background and...| Read more »
