摘要： A method and system of controlling at least one printbar in a printing system are described. The printing system has one or more of printbars distributed along a media transport. A first image including a reference pattern is generated on a print medium with a first printbar. A pattern is then detected on the print medium. The reference pattern and the detected pattern are used to determine a position of the first image relative to a second printbar. This position is used to configure nozzle data for a second image to be generated on the print medium by the second printbar.

摘要： A flatbed scanner includes a transparent window and an optical ruler close to the transparent window along a scanning direction. The optical ruler has at least one oblique line arranged thereon. The flatbed scanner includes a scanner head having a scanning width larger than the width of the transparent window for capturing an image of the optical ruler while the scanner head is being progressively moved by a step motor. The flatbed scanner further includes a processing unit for calculating a jag width of a captured oblique line in the captured image and a controlling unit for controlling the step motor to adjust the speed of movement of the scanner head according to the jag width of the captured oblique line.

摘要： An image reader includes an original transport device to transport an original, and an image reading device including multiple image sensor arrays having image reading areas staggered relative to the transport direction of the original in such a manner that the multiple image sensor arrays are offset at least partially, in the main scanning direction of the original with a predetermined gap therebetween in the transport direction. There is at least one original transport speed detector to detect the transport speed of the original transported by the original transport device, a storing device to store a reference delay time period which is between when the image sensor arrays on the upstream side read a predetermined position relative to the transport direction and when the image sensor arrays on the downstream side read the predetermined position. Further, there is a misalignment amount calculator, and an image synthesizer to synthesize an image read by the image sensor arrays.

摘要： A hand-held, portable, contact scanner using CCD scanning technology in conjunction with power regulation, noise reduction and image stitching. The scanner uses various movement tracking technologies to determine when the scanner is in contact with a document to be scanned. A dual roller system is used to effectively track motion of a contact scanner 100 across a target document. Alternatively, movement detection is performed by a reflected laser or infra-red (IR) output.

摘要： A hand-held scanning system and method thereof are described. A look-up table is created to generate a mapping relation between a plurality of reference amplitudes and a plurality of corresponding sampled positions. An analog-to-digital converter samples an analog signal and converts it into a digital signal. The digital signal represents a mapping relation between the sampled positions of the movement distance and the corresponding scanning amplitudes of the signal intensity. The hand-held scanning system ascertains the sampled positions corresponding to a former scanning amplitudes and a present scanning amplitudes according to the look-up table during the scanning stage for detecting the position variation status to determine whether the trigger signal is activated for image scanning or not.

摘要： A method of controlling a digital printing system that uses multiple metadata packets is provided. A controller including a metadata channel is provided. Information in a first metadata packet that is associated with an initial point of interest of a media is provided by a primary metadata packet creation unit. The first metadata packet is inserted into the metadata channel of the controller. A second metadata packet including new information associated with a new point of interest of the media is created using a secondary metadata creation unit. The second metadata packet with the new formation is inserted into the metadata channel of the controller based on the location of the new point of interest of the media.

摘要： A frequency adjusting unit adjusts a frequency of the clock signal to be supplied to a drive unit when an image is to be formed on the second face in response to a contraction ratio of the printing material on which an image has been formed on the first face. The phase difference determining unit determines a phase difference between the clock signal corresponding to the first face and the clock signal corresponding to the second face in response to a frequency difference and a sign thereof between the clock signal corresponding to the first face and the clock signal corresponding to the second face. The change control unit changes from the clock signal corresponding to the first face to the clock signal corresponding to the second face.
