Preview of a document with printable components at a printing device based on its printing capability

Abstract: An apparatus, method, system and medium are described that support functionality to receive document(s) to be printed at a printing device, and enable editing the document(s) prior to printing. Modifications to the document(s) may be generated based on the user edits, and a print preview of the modified documents may be displayed and may enable further edits. In some embodiments, the print preview may be provided to the user on a display that is part of the printing device. In some embodiments, the print preview may be provided to the user through a UI presented on a client device. Display of the modified document(s) may be a rasterized image of the modified document(s), generated based on capabilities of a selected printing device. In some embodiments, modifications may be made to an intermediate version of the document(s), and that intermediate version may be cached.

Method and apparatus for testing CMOS image sensors

Abstract: A method and apparatus which enables fast testing of light sensing integrated circuits is disclosed. The integrated circuit is positioned in a test head which includes a light source output providing a flat field light to shine on the light sensing portion of the integrated circuit under test. The light is provided to the light source output through an optical fiber from a light box which includes electronic filtering and shutter operations. Light is provided to the light box through another optical fiber from a precision light source. The operation of the light box, including adjusting filtering characteristics and shutter timing is controlled from a tester which also controls the integrated circuit under test in the test head. A high speed data link couples output signals from the test head to dedicated signal processing circuitry which analyzes the output signals to determine whether the integrated circuit passes or fails testing. The optical system including, for example, a liquid crystal filter which can be controlled very quickly, and the dedicated signal processor and high speed data link allows testing of integrated circuits to be carried out at a very high speed.

Method and apparatus for color image correction

Abstract: A method and apparatus of image processing is disclosed. The method and apparatus accomplish image processing by separating a luma component and a chroma component of an image signal. Averaging of at least some of the image pixels of the luma component is done over a plurality of image pixels to provide a plurality of surround function values. Retinex-like processing of the luma component is done using the surround function values to provide a Retinex-like processed luma component. The Retinex-like processed luma component is added to the chroma component of the image signal to provide a processed image signal.

Optical drive controller with a host interface for direct connection to an IDE/ATA data bus

Abstract: A compact disk drive controller to control the access of information from an optical compact disk (CD) digital data storage device by a host computer using an integrated drive electronics (IDE) data bus or an industry standard architecture (ISA) data bus is disclosed. A digital signal processor (DSP) interface to the drive electronics of the CD drive, a dynamic random access memory (DRAM) controller, an error correction code (ECC) data corrector, an error detection and correction (EDC) device employing cyclical redundancy checking techniques (EDC/CRC), and a host computer interface are described.

Method and means for block floating point arithmetic

Abstract: Circuitry for use in operating on block floating-point data where all data in a block has a scale factor associated therewith including a maximum scale register for storing the maximum scale factor of the data in a block, a subtractor for obtaining a difference value between the maximum scale factor and a data scale factor as the data is retrieved for operation, and a computer for adjusting the scale of retireved data by the difference prior to operation on the data. As the data in a block is operated on scale overflow is stored and used to adjust subsequent data as read from memory prior to operation thereon. A counter is provided for counting all scale overflow as a result of operations on all data in a block with the maximum scale register being updated based on the total count following operations on all data in the block.
