Принадлежит: Canon Inc

An optical scanning apparatus capable of properly correcting a main scanning scale factor. Upstream and downstream laser-light detection sensors of the optical scanning apparatus each generate a signal when first or second light beam passes through each of slits formed in the sensors. Based on signals, a scanning time required for each light beam to scan between the sensors is measured. A correction coefficient is decided by a correction value calculation unit based on a difference between wavelengths of the first and second light beams, a scanning time difference is calculated by a comparison unit based on the correction coefficient and scanning times of the light beams, and the downstream laser-light detection sensor is rotated by a sensor rotation drive unit to make the scanning time difference zero, whereby the slits are made parallel to each other.

Commands, which are stored in a queue within controllers in order of acquisition, are transmitted to mechanical I/F units (steps ( 1 ) and ( 2 ) in FIG. 7 ). A determination portion in each mechanical I/F unit determines whether or not the command is an internal command (for example, an error command) which is generated in the controllers. If the command is the internal command, the command is directly output to the mechanical controller. In contrast, if the command is not the internal command, a virtual mechanical controller outputs the command through synchronization processing for confirming whether the commands issued from the controllers are synchronized (steps ( 3 ) to ( 7 ) in FIG. 7 ).

In order to achieve this, the number of dots that are printed in pixels is adjusted according to the density level so that the number of dots that are printed in pixels corresponding to boundary portions is larger than in pixels corresponding to areas that are not boundary portions, and so that the number of dots that are printed in pixels corresponding to boundary portions increases the higher the density level of the pixels is. As a result, it is possible to avoid the occurrence of white stripes in high-density areas without emphasizing black stripes in low-density areas.

A print data conversion area can be created to reflect that all printed slips are not the same size. A printer includes a conveyance unit that conveys checks with one edge following a guide extending in the conveyance direction, a length detection unit that detects the length of the conveyed check in the conveyance direction, and a conversion area formation unit that creates a print data conversion area to which print data for the entire image to be recorded on the check is written. The conversion area formation unit determines the range of the conversion area with reference to a position corresponding to a particular position on the check using the detected length of the check in the conveyance direction.

Wireless synchronization of data and software components over IEEE802.11 standard(s) are herein disclosed and enabled. An information apparatus, which includes a wireless communication unit compatible with IEEE802.11, may access a wireless local area network (WLAN). To setup the wireless synchronization, the user connects the information apparatus to a wireless output device over a wired connection (e.g., USB) and selects the wireless output device. Information associated with the wireless output device is saved in the mobile information apparatus for enabling wireless synchronization. Next, the user connects the mobile information apparatus to the WLAN, and, depending on the availability of the wireless output device in the network, the information apparatus may lock a wireless connection to the wireless output device for wireless synchronization. A client application in the mobile information apparatus and output controller software in the wireless output device may be required to facilitate the wireless synchronization over the WLAN.

The invention solves the problem of the layout of the printout being broken as a result of the host computer sending the next print data without knowing the current printing position after the printer automatically inserts a new line. In a printing system that communicates continuous print data and status information by command between a host computer and a printing device, the printing device prints while automatically inserting a new line in the continuous print data received from the host computer according to a print setting, and sends current position information as status information to the host computer. The host computer sends the next continuous print data based on the acquired current position information.

A method for enhancing detail information in rasterized, continuous tone images includes a function that enlarges the contrast of a pixel in a neighborhood of pixels when in that neighborhood one of the pixels has a value that is close to a white color. This is determined by selecting the whitest pixel in the neighborhood. The function shows a gradual transition between the situations in which the whitest pixel is close to the white color and in which the whitest pixel is far from the white color. The method results in a better rendering of fine print when the image is sent to a printing system that reproduces the image on receiving material. For small characters, the legibility is improved by application of this method.

A method for reducing an amount of marking material for printing a binary image on a receiving material uses a printing process configured to apply print pixels and to associate each image pixel with at least two print pixels. A print signal is generated indicating for each print pixel whether marking material is to be applied. The print signal is filtered by a predefined mask that defines for which print pixels no marking material will be applied independent of the pixel value of the associated image pixel. The print pixels that are blocked by the mask define a regular pattern to avoid graininess in the printed image. The main effect on print quality is a reduction of the contrast in the image. By choosing one of a set of at least two masks, the user selects the amount of reduction that is realized in the print process. 1. A method for reducing an amount of marking material to be used for printing an image on a receiving material using a printing process , the image comprising image pixels , each image pixel having a pixel value selected from a first value indicating that marking material is to be applied and a second value indicating that no marking material is to be applied , wherein the printing process is configured to apply print pixels and wherein each image pixel is associated with at least two print pixels , the method comprising the step of generating a print signal that indicates for each print pixel whether marking material is to be applied or not based on the corresponding pixel value , wherein the step of generating the print signal comprises filtering the print pixels using a predefined mask that defines for which print pixels no marking material is to be applied independent of the pixel value of the associated image pixel.2.

A method for printing an image with colour pixels is disclosed. This method optimizes the print quality for a selected level of ink usage by maximizing a dot-off-dot strategy and separating between direct binary search dot patterns for a number of selected colorants in a printer comprising black colorant. Ink usage is controlled by determining the fraction of coinciding printer colorants that may be substituted by black colorant. The perceived error between the image pixels and the image dot pattern is minimized according to a human visual system model that excludes non-homogeneous patterns that affect the quality of the halftone textures. Dots for other colorants are processed independently and added to the obtained halftone dot pattern for the selected colorants. 1.

Method for semi-correlated halftoning

Номер: US20130188226A1
Автор: Carolus E. P. Gerrits
Принадлежит: Oce Technologies BV

A method for image processing a digital color image uses a single array of threshold values in a halftoning process if a total density value, which is found adding up the color density value for each of the process colors of a pixel, is lower than a predetermined density threshold. However, when the total density value exceeds the density threshold, the individual color density values are split in a basic part and an excess part, the basic parts adding up to the predetermined density threshold. In the halftoning process the basic parts still use the single array of threshold values, but the excess parts use uncorrelated arrays of threshold values that are associated with each individual process color. This provides for a balance between graininess at low color density and registration independent color rendering at high color density.
