摘要： A keyboard device includes at least one luminous key, at least one light-emitting element, a membrane switch circuit member, an opaque seal structure, and a transparent seal structure. The luminous key has a light-transmissible zone. The light-emitting element is electrically connected with the membrane switch circuit member, and disposed under the light-transmissible zone. A top surface of the light-emitting element is encapsulated by the transparent seal structure. The transparent seal structure is partially surrounded by the opaque seal structure. Consequently, the light beam from the light-emitting element is transmissible through the transparent seal structure, and directed to the light-transmissible zone.

摘要： A system and method for enhancing digital images containing both text and pictorial content (“mixed document images”) utilizes an estimated illumination surface for a given digital image to correct the undesirable effect of non-uniform illumination. The estimated illumination surface is based on the luminance values of the edge pixels of the given image that are on the dark side of text edges. In an alternative embodiment, the luminance values of the edge pixels that are on the lighter side of the detected text edges are used to generate the estimated illumination surface. The estimated illumination surface is applied to the digital image to compensate for illumination variations in the image due to non-uniform illumination. In addition to non-uniform illumination correction, the system and method enhances the mixed document images by sharpening and/or darkening edges of text contained in the images.
