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.

摘要:
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.
