摘要： Image data in an image scanner is examined to determine whether lines (light or dark) are present in the image data. By examining whether the lines are present in image data for multiple colors, and whether calibration gains for corresponding photosensors are normal, it can be determined whether the lines are likely caused by a surface defect, on a calibration target, or on a platen, or on an image being scanned.

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： Transparent documents with precoated background so that only the text and foreground need to be printed by a printer is taught. Alternatively, the transparent documents may be precoated with watermarks, company logos, company confidential or other common background patterns. The printer may be able to selectively remove the background precoating from predetermined areas of the transparency where text or other foreground material will be printed. Alternatively, the ink in the printer may chemically dissolve the precoating in predetermined areas.

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： An integrated image capture device and a desk and floor lamp. The image capture device is adapted to plug or screw into the light bulb socket of the lamp so that the image capture device may obtain power from the light bulb socket of the lamp when the lamp is plugged into a wall socket. The image capture device may also have a ‘pass-through’ socket adapted to receive a standard light bulb so that the standard light bulb may provide additional light for the image capture device. The image capture device may also provide modulation to the light bulb in order to perform exposure control. The image capture device may also provide color compensation by measuring the intensity and color of the light from the light bulb. The image capture device may also perform data transmission through the power cord of the desk or floor lamp.

摘要： A system and method are disclosed which provide a look-down digital imaging device capable of scanning a calibration area included within such look-down digital imaging device to capture image data for the calibration area and calibrate itself based on analysis of such captured image data. More specifically, a preferred embodiment includes a calibration area that is integrated internally within the look-down digital imaging device. When performing calibration in such a preferred embodiment, the scan head of the look-down digital imaging device is operable to align itself with the calibration area to allow for a scan of the calibration area (i.e., the capture of digital image data of the calibration area). In one embodiment, a look-down digital imaging device does not achieve a focused scan of the calibration area, but is capable of utilizing captured unfocused digital imaging data for calibration. In a preferred embodiment, a look-down digital imaging device achieves a focused scan of the calibration area, thereby enabling a further accurate calibration. More specifically, a preferred embodiment folds the optical path of the reflected light from the calibration area in order to have the optical path of such calibration area accurately mimic the optical path of an original to be scanned, thereby allowing for focused calibration to be achieved.

摘要： The tonal resolution of an image scanner is improved by adjusting the dynamic range of an analog-to-digital converter of the scanner. A preview scan of the image is made. The image data from the preview scan is then analyzed to determine a maximum intensity and a minimum intensity. The value of the maximum intensity is used to set a white intercept of the image scanner such that a maximum digital value of the analog-to-digital converter corresponds to the maximum intensity present in the image data from the preview scan. The minimum intensity is used to set a black intercept of the image scanner such that the minimum intensity in the image data from the preview scan corresponds to the minimum digital number output by the analog-to-digital converter. Tonal resolution of the image scanner is optimized then by performing a final scan of the image with the analog-to-digital converter programmed to reflect the new white intercept and black intercept values.
