摘要： A method for decoding data that has been encoded in a monochrome medium utilizing the capability of the medium for grayscale resolution. A document is processed to provide an image in electronic format, in which each pixel has an assigned data value with a given bit depth. A mapping operation is performed for generating a monochrome data word (120), preferably having a reduced bit depth. The monochrome data word (120) can be used to encode multiple data fields (114, 116, 118). A printer (92) then produces a preserved document record (90) in which the appropriate monochrome data word (120) determines the grayscale value for each pixel. To decode the stored data, a scanner (86) is employed to obtain the grayscale value from the preserved document record (90). For each pixel, the grayscale value is then decomposed into multiple data fields (114, 116, 118), which can then be decoded to provide the information that was originally encoded.

摘要： An apparatus and method for printing images from a digital image source onto a photosensitive medium (22) using one or more two-dimensional light-emissive arrays (51) such as OLED arrays. Each image pixel has a corresponding light-emitting element which is assigned a variable intensity based on data for that pixel. Imaging optics (58) direct the light from each light-emitting element onto the photosensitive medium (22) so that a monochromatic or multicolor image can be formed with a single exposure.

摘要： A printhead having a plurality of exposure elements (18) with improved non-uniformity correction. Spatial variance of the energy emitted by the exposure elements (18) is measured and used to establish spot size characteristics for each exposure element. A sensor (26) scans multiple points along the pixel area written by each exposure element (18) and measures a corresponding output power value at each point. The output power values are evaluated to determine a maximum output power value for the exposure element (18) and to obtain a spot size for the exposure element (18) based on full-width at half-power values. Both spot size data, which can thus be obtained and stored only once, and output power values are then used to correct for non-uniformity's between the exposure elements (18).

A state of each of the elements is controlled according to the digital image data. An optics assembly (11) is used for directing the polarized beam to the modulator and the exposure beam from the spatial light modulator (52). A lens assembly (132) is used for directing the exposure beam onto the photosensitive medium (160).
