    Abstract: PROBLEM TO BE SOLVED: To provide a controller and a control method for an image display capable of eliminating an influence of an environmental light source. SOLUTION: This controller for controlling the image display 10 is provided with reference objects 12, 14 for generating a prescribed light spectral signal, a modulation part 16 for modulating the prescribed light spectral signal by a prescribed method, and a remote controller 20. The remote controller 20 is provided with an image sensor 24 for receiving the modulated prescribed light spectral signal and for generating a digital signal DS, and a signal processing means 26 for receiving the digital signal DS to be demodulated, for generating a digital image containing only images of the reference objects, and for calculating image variations of the images of the reference objects on the digital image. The remote controller 20 controls therein the image display 10, based on the image variation of the images of the reference objects, and eliminates the influence of other light source generating light of a band overlapped with a band of the prescribed light spectral signal.

    Abstract: There is provided an image display including a first light source, a second light source and a modulation unit. The first light source has a plurality of first point lights arranged to form a first shape for generating a predetermined spectrum signal. The second light source has a plurality of second point lights arranged to form a second shape for generating a predetermined spectrum signal. The modulation unit is for simultaneously modulating the first point lights of the first light source with a first predetermined modulation frequency and for simultaneously modulating the second point lights of the second light source with a second predetermined modulation frequency to generate a modulated predetermined spectrum.
