摘要： A method of white balancing an image includes mapping pixels of the image to a color space diagram. Each of the pixels of the image include a red (“R”), a green (“G”), and a blue (“B”) subvalue. A first central tendency of each of the RGB subvalues of pixels mapped in a first pre-defined region of the color space diagram is determined and a second central tendency of each of the RGB subvalues of pixels mapped in a second pre-defined region of the color space diagram is determined. The first pre-defined region is associated with a first illuminating source and the second pre-defined region is associated with a second illuminating source. RGB values of a white pixel are generated based on the first and second central tendencies.

摘要： A method for generating a control signal to control an information technology device includes the following steps: (1) capturing, using an image sensor, a current control image of a light source of a remote controller positioned within a field of view of the image sensor; (2) identifying, within the current control image, a current location of light emitted from the light source; (3) determining movement between (a) the current location of the light emitted from the light source and (b) a previous location of the light emitted from the light source determined from a previously captured image; (4) generating a movement control signal based upon the movement; and (5) sending the movement control signal to the information technology device. The method is executed, for example, by a movement control module of an information technology device input system.
