Abstract: A display apparatus has a friction surface which makes friction force between a base and a support surface on a lower surface of the base that supports the display body, in which the friction surface has a high friction surface having a relatively high friction coefficient and a low friction surface having a lower friction coefficient than that of the high friction surface, and the low friction surface protrudes further than the high friction surface.
Abstract: A video processing device includes: a deserializer that both converts a serial digital interface signal received as input to parallel data and extracts a clock; format detection means that both detects a video data format that is included in the parallel data that were converted by the deserializer and supplies clock ratio information that indicates the ratio of the clock frequency and the pixel clock frequency stipulated by the format; pixel clock generation means that generates a pixel clock based on the clock that was extracted by the deserializer; saving means that saves video data and supplies the saved video data in synchronization with the pixel clock; write control means that, based on the clock ratio information, divides the video data that are contained in the parallel data that were converted by the deserializer into two or four portions and saves the divided data in the saving means; and an unpack processor that, synchronized with the pixel clock, subjects the data that are supplied from the savin
Abstract: An electronic device of the present invention includes an input acceptance section that accepts an input of a command that causes any one of a plurality of operation states to be selected; a function section (342) that has a plurality of operation states that differ in power consumption and that operates in an operation state represented by the command that is input to the input acceptance section of the plurality of operation states; a storage section (16) that pre-stores power consumption values corresponding to the plurality of operation states and a conversion factor, based on which, power consumption is converted into an amount of emitted greenhouse gas; and a control section (15) that reads from the storage section a power consumption value corresponding to an operation state represented by the command that is input to the input acceptance section, multiplies the power consumption value that has been read by the conversion factor, obtains the multiplied result as the amount of the emitted greenhouse gas
Abstract: An image display apparatus includes: a panel (16a) that includes a plurality of picture elements that change transmittance of light according to picture levels; a detection unit (12) that detects, in one-image portions of the panel (16a), picture levels for each of the plurality of picture elements from picture signals that indicate the picture levels of each picture element; and a processor (18) that, based on the picture levels of one-image portions that were detected by the detection unit (12), adjusts the transmittance of light of the plurality of picture elements such that the image realized by the picture signal is brighter when a value that corresponds to brightness is greater than a predetermined threshold value.

Abstract: In one embodiment, the present invention provides a method and apparatus to insure continuous presentation of digital content to an audience when a locally stored copy of a file containing the digital content suddenly becomes unavailable to a digital projector. In one embodiment of the method, a first computer generates a first command to read a first block of data from a file stored on a first memory device, wherein the first computer system is coupled to a digital projector. The first computer system also generates a second command, which is subsequently transmitted to a storage device external to the computer system. The external storage device includes a hard disk that stores a copy of the file that is stored on the first memory device or vice versa. The external storage device includes a read/write head.

Abstract: The present invention has as its object providing a terminal capable of accurately searching for an apparatus installed near a user. The terminal connected to a network apparatus through a network includes a display section which performs a displaying operation and position searching means which, on receiving an instruction to make a search for the network apparatus, transmits a signal indicating specific content and then, on receiving a response signal from the network apparatus that receives the signal through the network, causes the display section to display information that shows that the network apparatus transmitting the response signal has received the signal.
