Abstract: When a user indicates a point on a display screen of a computer using a pen sensor, first the display screen is divided into a plurality of areas and the areas are displayed by mutually different colors or brightnesses. The plurality of colors or brightnesses displayed are scanned by the pen sensor and the colors or brightnesses detected by the light receiver to judge in which area the indicated point is located. Next, the judged area is further divided into a plurality of areas which are displayed by mutually different colors or brightnesses. Next, a routine similar to the above is successively repeated to narrow down the area in which the point indicated by the pen sensor is located and finally determine the position of the point, that is, the XY coordinates on the display screen.

Abstract: An electronic apparatus having functions to be expanded by first and second function expanding media includes a connector that is connectable electrically to an adapter, the adapter having a first insertion opening into which the first function expanding medium is detachably inserted, and a second insertion opening into which the second function expanding medium is detachably inserted, and a housing that has first and second surfaces, and accommodates the adapter, the first surface having a third insertion opening that exposes the first insertion opening, and the second surface being arranged substantially orthogonal to the first surface and having a fourth insertion opening that exposes the second insertion opening.

Abstract: In an image display apparatus in which a display attribute of a specific area of the display can be modified based on an information input from a processor, a resolution of the image is determined from the input vertical and horizontal synchronization signals, dot clocks are generated by multiplying the horizontal synchronization signals depending on the determined resolution, a horizontal display period in one horizontal synchronization signal is detected using a signal in the image signals input from the processor, the actual count value of the dot clocks in the detected horizontal display period is compared with a standard value thereof in the horizontal display period in one line at the determined resolution of the image and the multiplication number of a dot clock generation circuit is corrected so that the count value coincides with the standard value to modify the display attribute of the specific area of the display.

Abstract: An information processing apparatus includes a tuner receiving a signal according to a received broadcast, a first processing part performing a desired processing on the signal supplied from the tuner, converting the signal into a first signal of a given format, and outputting the first signal, a second processing part converting the signal supplied from the tuner into a second signal of the given format and outputting the second signal, and an output part selectively outputting one of the first and second signals. The first and second processing parts are startable independently of each other.

Abstract: A storing part stores image data of an input image signal; and a control part detects a resolution of the image data from a synchronization signal which is in synchronization with the input image signal, and, controls timing of reading the image data from the storing part according to the thus-detected resolution. The control part detects periods of a horizontal synchronization signal and vertical synchronization signal which are in synchronization with the input image signal, determines a magnification for an image to be output, from a horizontal synchronization interval and a vertical synchronization interval of the image to be output, and the periods of the horizontal synchronization signal and vertical synchronization signal which are in synchronization with the input image signal; and controls the timing of reading the image data from said storing part according to the thus-determined magnification.
