摘要:
Provided is a technique of correcting influences of optical environment to correctly recognize the color of an input object used for inputting of coordinates, and enabling automatic designation of a color to be used for drawing. A coordinate detection unit detects coordinates of an input object. Next, display light on the display plane in the vicinity of the coordinates is estimated from display data, and a correction value to remove influences of the display light is calculated. A captured image of an input object used for input operations on the display plane is extracted, and the color of the captured image is corrected with a display light correction value. Thereby, influences of the display light added to the input object are removed, enabling the original color of the input object to be identified.

The main object of the invention is to provide an electromagnetic wave resonator making use of surface waves: an electromagnetic wave resonator structure capable of being achieved with existing technologies yet without much difficulty and applying voltage to a positive dielectric area, thereby overcoming a variety of problems arising from the fact that only thermal excitation is available.The contact structure of negative dielectric/positive dielectric/negative dielectric necessary for this type of electromagnetic wave resonator is provided on the surface of the negative dielectric material 1 just as the coaxial structure of the positive dielectric thin film 3 extending in the Y-axis direction and the negative dielectric material 2 received therein is cut in the axial direction. This makes sure both negative dielectric materials 1 and 2 with the positive dielectric thin film 3 sandwiched between them are electrically insulated so that voltage can be applied to the positive dielectric thin film 3, and ensures that an area provided in the negative dielectric material 1 to receive the positive dielectric thin film 3 has an aspect ratio D/P1 of about 1.9, a figure well achievable in the state of the art.
