Abstract:
1. A LED light illuminating control system for an electronic device, wherein the electronic device is connected to a detecting unit positioned in a room for determining whether or not a person comes into the room, a capturing unit positioned on a ceiling of the room for capturing an image on a floor of the room, and a plurality of LED lights aligned on the ceiling, the electronic device comprises at least one processor to execute all modules of the LED light illuminating control system and a storage unit to store a size of the ceiling, an image which includes no person on the floor in a circumstance that all the LED lights are turned on, and predefined set of coordinates, the system comprising: a LED light control module to turn on all the LED lights when the detecting unit detects that a person comes into the room; a capturing control module to control the capturing unit to capture an image including the person on the floor and store the captured image; an image processing module to perform image processing for the captured image which includes the person on the floor and the stored image which includes no person on the floor; an image comparing module to compare the captured image with the stored image to acquire differences between the two images; and a position determination module to calculate a size of the captured image and acquire a body area of the differences in the captured image based on the stored predefined set of coordinates, determine to turn on or off one or more of the LED lights for an illumination area for the person on the ceiling based on a ratio between the size of the captured image and the size of the ceiling and generate a control signal, the LED light control module further to control the one or more LED lights within the illumination area on the ceiling to maintain current illumination state and turn off rest of the LED lights on the ceiling in response to the control signal.
