A cloud server includes an equipment information storage that stores equipment table information; an equipment controller that generates control information; an encapsulator that generates control notification information by encapsulating the control information and adding header information for specifying a control device as a sending destination; and a notification information sender that sends the control notification information to the control device based on the header information. Upon acquiring the control notification information from the server, the control device removes the header information from the control notification information and decapsulates to extract the control information, and sends the extracted control information to a controlled equipment.

A simplified menu includes menu items of a 'user menu' in which a user can change and customize a menu, a 'user menu selection' for selecting a menu item capable of being set in the user menu, and a &#x201c;detailed menu switch&#x201d; for switching the menu from a simplified menu to a detailed menu. The &#x201c;user menu selection&#x201d; is displayed in the simplified menu, which is not a menu of a different hierarchy. Accordingly, the user can perform an operation in the simplified menu.

Image display apparatus

An image display apparatus includes an input range discriminator which discriminates a type of an input digital video signal, on the basis of a setup level and a dynamic range of the digital video signal; a signal processor which corrects the setup level and the dynamic range of the digital video signal, on the basis of a result of the discrimination made by the input range discriminator; and a display device which displays a picture based on the digital video signal corrected by the signal processor.

Setup level and dynamic range adjustment of an image display apparatus

A display device body includes an image display section for displaying an image, a first power supply section for supplying power to the image display section, an anti-theft section for preventing the display device body from theft, and a second power supply section for supplying power to the anti-theft section. The anti-theft section includes a vibration sensor for sensing a shake of the display device body, a vibration detection section for detecting a vibration based on an output level from the vibration sensor, a state retention section for selectively retaining one of a cautionary state in which caution is taken against the theft of the display device and an alarming state indicating that the display device is being stolen, an alarm section for issuing an alarm when the state retention section is in the alarming state, and an operation control section.

Display device

A projector comprises an optical engine which projects an image based on a video signal; a circuit section which controls operation of the optical engine; a power source which supplies electric power to the circuit section; a network interface, through which the circuit section communicates with a remote network terminal device; and a hub which is connected to the network interface and includes a plurality of ports. The network interface communicates with the remote network terminal device through one of the ports of the hub. Further, the power source of the projector supplies electric power to the hub.

An image is scaled by a desired scaling factor by using an upper scaling factor slightly greater than the desired scaling factor and a lower scaling factor slightly less than the desired scaling factor. The upper and lower scaling factors are applied to different parts of each horizontal or vertical line in the image. Both the upper and lower scaling factors are fractions with numerators and denominators less than the numerator and denominator of the desired scaling factor. The lower scaling factor may be obtained by decomposing the desired scaling factor into unit fractions. Regardless of the value of the desired scaling factor, the image can be scaled without the need for a large interpolation coefficient memory, and without resorting to iterated scaling and its attendant large data transfers.

Scaling method and apparatus using approximate simplified scaling factors

A dichroic mirror for reflecting red light for optical separating and a dichroic mirror for reflecting red light for optical synthesizing are installed on the same plane in an image generating apparatus of the present invention. In addition, a dichroic mirror for reflecting blue light for optical separating and a dichroic mirror for reflecting blue light for optical synthesizing are installed on the same plane. Accordingly, a compact configuration can be realized. Since a main reflecting mirror is a rotating elliptic mirror and a lamp is located on a focus or around the focus, a lighting equipment which irradiates conic luminous flux can be realized.
