摘要： Pointing devices and related methods are disclosed that generally involve manipulation of a cursor or other user interface component based on inputs from a user. In one embodiment, an image sensor captures an image of the underside of a transparent contact surface and determines whether an object (e.g., a user's finger) is present in the image. Cursor movement information comprising direction and velocity components can be calculated from a single image by equating the size of a detected object with a desired velocity and by equating the position of the detected object relative to a fixed reference point with a desired direction. Thus, detection of user motion is not required, nor is comparison of successive image frames relative to a time reference. As a result, a device having few or no moving parts can be provided while at the same time permitting continuous cursor motion without repetitive swiping by a user.

摘要： A technique is provided for improving visual recognition of letters, graphics, etc., in a portion of a displayed image that has been enlarged. An image display system includes an image display component for displaying on a screen an image based on image data, a region indicator component for permitting a region to be enlarged from the image to be selected and identified, a data modification component for modifying the portion of the image data corresponding to an enlarged display region so that the selected image is enlarged and displayed within the enlarged display region on the screen, and a brightness adjusting component for adjusting values instructing brightness of the corresponding image data part such that a contrast of the image within the enlarged display is higher than a contrast of the original image within the enlarged display region.

摘要： In a portable computer, an LED holder is provided in the upper portion of an LCD and an LED is attached inside the LED holder. Light emitted from the LED passes through an aperture provided in the bottom portion of the LED holder and illuminates a keyboard. Furthermore, switching on or off the LED is manually performed by a switch installed in the portable computer and is also controlled from a utility program, etc., by a switching controller circuit installed inside a main body.

摘要： Disclosed is an information processing system that can operate in at least two modes of power management, a normal mode and a suspend mode. The system can enter the suspend mode in response to the expiration of an inactivity suspend timer and can resume therefrom in response to a resume request. While resuming, the system is operative to measure an elapsed time between entering the suspend mode and resuming therefrom. The system is further operative during the resume to either (1) prompt a user to enter a password if the elapsed time is longer than a predetermined time or (2) skip (1) and not prompt a user to enter a password if the elapsed time is shorter than the predetermined time. The system decreases the amount of time required to resume from a power saving mode by not requiring a password input when a resume request by a user, such as key input, occurs within a relatively short period of time after the system entered the suspend mode.
