摘要
The detection of ambient light on an optical touch-sensitive device is disclosed. For example, one disclosed embodiment comprises capturing an image of at least a portion of a display screen with a camera located within the display device, and determined if ambient light in the image is at an acceptable level for display screen operation. Then, a visual representation is displayed representing whether the ambient light level is acceptable for display screen operation.
