摘要： A multiple image scanner that performs a single scan of a document containing different types of images (e.g., text and graphics) and sends multiple renditions of the same document from the scanner to a host computer (e.g., one high resolution gray scale image and one low resolution high bit depth color image; or one high resolution, low bit depth gray scale or monochrome image and one low resolution, high bit depth gray scale or monochrome image; or one high resolution, low bit depth color image and one low resolution, high bit depth color image), thus greatly reducing the total amount of data sent to and processed by the host computer.

摘要： An image capture system comprising a scanner having a 10-bit analog-to-digital converter. The scanner operates within an environment that includes a host computer that is configured to accept 8-bit data. The contrast enhancement of the scanner is improved by applying an improved tonal adjustment on a scanned image. The host computer connected to the scanner provides an 256-value to 256-value look-up table (i.e., the 8-bit tone map) to the scanner. The scanner generates an interpolated 1024-level to 256-level look-up table (i.e., a 10-bit tone map) from the 256-level to 256-level look-up table. The 1024-value to 256-value look-up table is generated by using linear interpolation and extrapolation. The scanner can thus provide better contrast enhancements without having to modify the software running on the host computer.

摘要： A method for dynamically determining and adjusting the color balance of the light strip along one edge of the scanned area and adjusting the gains of independently controlled red, green and blue channels of a CCD array. Alternatively, the gain of one color channel may be held constant and measured to determine the light intensity of the light source as the temperature of the light source varies. The power to the light is then changed to maintain the intensity of the light source within a predetermined range. The three color channels are then compared to a predetermined color balance. If the color balance is outside of a predetermined range, the other two color channels gains are varied in order to maintain the color balance between the three color channels.

摘要： A system and method for improving the signal to noise ratio of a CCD sensor within an optical scanner varies the exposure time of the CCD sensor. Exposure time is varied by clocking the CCD sensor a number of times equal to the number of pixels in the CCD sensor plus an additional number of clock cycles to create a delay. The additional exposure time maximizes the magnitudes of the charges produced by the CCD sensor. The required delay is computed during a pre-scan calibration step.

摘要： An image scanning system for producing digital data of a predetermined resolution representing a scanned image of an original. The system includes a photosensing array for generating the digital data, a stepper motor having steps of predetermined size for positioning the array with respect to the original, an image buffer for storing the data and control system for synchronizing the scanning and the storing of data at one or more Y-positioning speeds. Scan line extents along the Y-direction are defined by the relationship of the Y-positioning speed to the array exposure time. The scan lines in conjunction with the present invention have boundaries, wherein the boundaries can occur on or between said motor steps.

摘要： A method for determining when overall lamp intensity is stable for a lamp in a document scanner. The intensity of a relatively small portion of the lamp is controlled as part of a closed loop intensity control system. During a warm-up transient period, the intensity of the small portion of the lamp is monitored and power to the lamp is monitored. A changing power to the lamp indicates that the overall lamp intensity has not stabilized. Scanning is initiated when the intensity of the monitored portion of the lamp is within a predetermined control range and the power to the lamp has stabilized for a predetermined time period. The predetermined time period can be a default value or can be determined by a user.

摘要： A method of adjusting the resolution of a scan based on the scan area or the scan window size. The smaller the scan window size, the higher the scan resolution would be. The final scan resolution is a function of an initial resolution, a resolution modifier, a printer factor, and an image factor. The resolution modifier, the printer factor and the image factor are dependent on the scan window size, the system printer, and the scan image type respectively.
