Light emitted from a white LED 15 is converted by a lens 11 into light having an excellent directionality. The light illuminates a display panel 863 from the direction of an angle θ_k. The display panel 863 is a polymer dispersed liquid crystal display panel in a normally white mode. The display panel 863 modulates incident light by scattering it, the scattered light is incident on a magnification lens 866, and light from the magnification lens reaches an eye 21 of the observer. Light which passes straight through a liquid crystal layer in the display panel 863 is absorbed by an optical absorbing film 12. The observer fixedly positions his/her eye 21 to an eyepiece cover 852 and observes the displayed image.

System and method for view navigation and magnification of the display of hand-held devices in response to the orientation changes along only two axes of rotation as measured by sensors inside the devices. The view navigation system is engaged and controlled by a single hand which simultaneously presses two ergonomically designed switches on both sides of the hand-held device. In other embodiments, the system engaged into the view navigation mode in response to an operator command in the form of a finger tap, or a voice command, or predefined user gestures. The response curve of the view navigation to sensed changes in orientation is dynamically changing to allow coarse and fine navigation of the view. Various methods are described to terminate the view navigation mode and fix the display at the desired view. Miniature sensors like accelerometers, tilt sensors, or magneto-resistive direction sensors sense the orientation changes. The system can be added to an existing hand-held device via an application interface of the device.

A capturing unit captures and digitizes a printed image having an electronic watermark embedded therein and a lattice pattern image. A profile creation unit detects position deviations of intersections in the lattice pattern images captured at respective different zoom magnifications, generates correction information on distortion occurring in the images, and registers the correction information into a profile database in association with the zoom magnifications. An image correction unit selects correction information corresponding to a zoom magnification employed at the time of capturing of the printed image from the profile database, and corrects distortion occurring in the captured image of the printed image. An image area determination unit determines an original image area in the distortion-corrected captured image. A watermark extraction unit extracts watermark information from the original image area in the distortion-corrected captured image.

In some embodiments, apertures may be added to the microlenses so that depth of field is increased.

A technique for generating high-resolution bitmaps from low-resolution bitmaps. A low-resolution bitmap is magnified to form a magnified image. Edge detection is performed on the magnified image to find high contrast edges. A plurality of image patches of the magnified image are generated. These images patches are analyzed by performing connected components analysis on each of them using the high contrast edges to produce a plurality of foreground and background decisions determining whether a portion of an image patch is a background or a foreground region. Then the contrast of one or more pixels in each of the plurality of image patches is enhanced based on the foreground and background decisions. Finally, the system and method of the invention combines the luminance of the enhanced output pixels with the color values generated by the magnification algorithm. This produces a high-resolution bitmap from the contrast-enhanced pixels.
