  • Interactive whiteboards and programs
    Patent number: 9024901
    Abstract: 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.

    Abstract: In a power supply device 1, a first space R1 and a second space R2 are delimited, a coil component 20 is arranged in the first space R1, and heat-generating components and components having weak resistance to heat are arranged in the second space R2. The power supply device 1 is configured to contain the coil component 20 in the first space R1 so that ambient air of the coil component 20 can contact a first side wall 72, which constitutes the first space R1, making it possible to expect discharge of heat to coolant in a coolant channel W via the first side wall 72. Therefore, heat can be discharged from the ambient air of the coil component, the temperature of which has been raised by heat generation, towards the coolant efficiently.
