One or more contone image processors receive the one or more raster images to perform cross-channel image processing to render the raster images into a form compatible with the marking engine, wherein the output is partially sub-partitioned by color separation. An image refactoring and distribution network completes the sub-partitioning by separation of the rendered contone raster images by color separation and distributes each color sub-partition to a marker channel module specific to each color sub-partition. A marking engine receives the color sub-partitioned image data, marks the image onto a substrate and outputs a hardcopy of the image. |

In an amplifying type MOS sensor having a 3-transistor construction, when a frame rate is raised, an accumulation time of a frame just after the switching of a drive mode becomes short. When a gain correction is made to compensate a lack of accumulation time, a deterioration in picture quality is caused. A read out scan and a reset scan are executed in parallel in the frame before the switching of the drive mode, thereby preventing that a time period for resetting a pixel is overlapped with a time period for holding a pixel signal into a holding unit. |

Identifying new semiconductor detector materials by D.C. ionization conductivity
Herein is described a method for identifying semiconductor radiation detector materials based on the mobility of internally generated electrons and holes. It was designed for the early stages of exploration, when samples are not available as single crystals, but as crystalline powders. Samples are confined under pressure in an electric field and the increase in current resulting from exposure to a high-intensity source of ionization current (e.g., 60Co gamma rays) is measured. A pressure cell device is described herein to carry out the method. For known semiconductors, the d.c. ionization current depends on voltage according to the Hecht equation, and for known insulators the d.c. ionization current is below detection limits. This shows that the method can identify semiconductors in spite of significant carrier trapping. Using this method and pressure cell, it was determined that new materials BiOI, PbIF, BiPbO2Cl, BiPbO2Br, BiPbO2I, Bi2GdO4Cl, Pb3O2I2, and Pb5O4I2 are semiconductors. |
