摘要:
A recognition processing unit (22) performs recognition processing on a scan image based on a signal read from a light sensor (2) and outputs coordinate data (Co) indicating the position of an object to be detected. A mode control unit (24) determines a normal mode in which the recognition processing unit (22) is operated or a standby mode in which the operation of the recognition processing unit (22) is stopped. A thinned image memory (25) stores a thinned image when the normal mode is switched to the standby mode. The mode control unit (24) switches the standby mode to the normal mode when a newly supplied thinned image changes from the stored thinned image by a prescribed amount or more. Thus, it is possible to rapidly leave the standby mode and quickly detect the contact position.

In a display device with optical sensors, a recognition processing portion (22) performs recognition processing on a scan picture generated by optical sensors (2), and calculates a position. A mode control portion (24) determines whether or not the mode is standby so that the recognition processing portion (22) is stopped from operating. At the time of transition to the standby mode, decimated image memory (25) stores a decimated image with a decreased number of pixels. The mode control portion (24) performs pixel-by-pixel comparison between the stored decimated image and a decimated image supplied anew, and exits the standby mode when the number of pixels whose difference in pixel values is greater than or equal to a first threshold is greater than or equal to a second threshold. Here, the first and second thresholds are appropriately set in accordance with an ambient luminance L from a luminance sensor (20), and therefore, any change in the image can be accurately distinguished from noise, thereby preventing the standby mode from being or not being cancelled by mistake.

A distribution management apparatus includes a generator configured to generate still-picture data from content data, a converter configured to convert the still-picture data into video data, and a distributer configured to distribute the video data to each of a first communication terminal and a second communication terminal, which are capable of playing back and displaying the video data. When first operation data indicating an operation of zooming into a partial region of the video data being played back and displayed on the first communication terminal is transmitted, the converter generates video data representing a partial region, which depends on display/playback capabilities of the second communication terminal, of the video data being played back and displayed on the first communication terminal, and the distributer distributes the video data representing the partial region generated by the converter to the second communication terminal.

In a system comprising the disclosed server and a plurality of player terminals, it is possible to suitably and easily alter the accessories and character class of player characters. The server has: a memory means that stores player character data of a plurality of player terminals; a means that confers data indicating the fact that a player character indicated in a party formation command has been added to the same party when a party formation command has been input from a player terminal; a means that acquires changes regarding the accessories or player class of the player character in each player terminal, and updates the character data stored in memory; a means that extracts the other players that form the same party as the player character for which changes have been output; and a means for transmitting said changes to the terminals of the other players that were extracted.

Provided are a polyimide which is inexpensive, has various excellent material properties including strength, heat resistance, low moisture absorption, mold releasability (detachability), dielectric properties, electrical properties, and optical properties, and can exhibit a high level of water repellency, and a polyamic acid composition useful as a raw material therefor. Also provided are the polyimide which can give a polyimide composition that, besides having such excellent material properties, is capable of having a controlled surface resistivity, and a polyamic acid composition useful as a raw material therefor. The polyimide is a highly water-repellent polyimide for copier members which is obtained using one or more acid dianhydrides and one or more diamine compounds, and is characterized in that at least one of the acid dianhydrides and the diamine compounds is a compound having an ether bond and/or a thioether bond in the molecule and that the total number of ether bonds and thioether bonds in the repeating unit constituting the polyimide and derived from the acid dianhydrides and the diamine compounds is 2 or larger.

Disclosed is a centering device of a spindle motor. The centering device includes a body portion which is disposed on the rotor of the spindle motor, and which is provided with a central hole for accommodating the shaft of the spindle motor; and a plurality of centering elastic finger units, located along the periphery of the body portion. Each centering elastic finger unit includes at least two elastic fingers. Each elastic finger includes a free end which extends from the body portion in the circumferential direction of the rotor, and which has a contact portion adapted to urge against an optical disk to guide the centering of the optical disk with respect to the shaft of the spindle motor. Preferably, the contact portion is formed into an arc surface so as to reduce the contact area and thus the friction between the elastic fingers and the disk.

Provided is a display device with photosensors that can achieve a scanner function without increasing the memory capacity for images. A display device with photosensors includes a visible light source and an invisible light source. The display device with photosensors further includes: a first photosensor that detects the amount of received light in a pixel region when the invisible light source is on; a second optical sensor that detects the amount of received light in the pixel region when the invisible light source is off; and a third photosensor that detects the amount of received light reflected from an object to be scanned, causing only display pixels respectively nearest to the third photosensors within a prescribed range in the pixel region to be in a display state, and causing other pixels in the prescribed range to be in a non-display state. Data obtained from the third photosensor is stored in a memory (205) including a region (205a) that stores therein first reference data obtained when the invisible light source is on, and a region (205b) that stores therein second reference data obtained when the invisible light source is off.
