摘要:
An image reading apparatus which has position deviated line sensors. The line sensors are formed by charge coupled devices which are arranged in two staggered rows. The signal from one of the charge coupled devices is delayed for a predetermined period corresponding to the distance between the rows, the speed of scanning and the reading density of the original. An actual timing deviation is calculated to delay one signal relative to the other so that the two signals will be output at the same time.

An office machine is disclosed, which comprises a second (lower) unit and a first (upper) unit capable of being opened and closed with respect to the lower unit. A plurality of light-emitting elements and a plurality of light-receiving elements are provided in the lower unit, and a plurality of light-emitting elements and a plurality of light-receiving elements are provided in the upper unit. The control signal and data signal are fed to the light-emitting elements to be converted into optical on-off signal. The light-receiving elements receive the optical signal and convert it into electric signal which is fed to necessary parts. Control signal lines and data signal lines between the two units are thus replaced with an optical relay.

A shadow printing operation is provided in a laser recording apparatus only for data which is detected to be character data. Line memories are utilized to store data therein, and examined to determine any change of stored data from non-character data to character data whereupon a shadow printing operation is also preferred.

In a recording apparatus, an image corresponding to the information is formed on a paper sheet in accordance with the data input from a data controller by a laser scanner unit. The size of the paper sheet on which the information is recorded is displayed by an LCD display in accordance with a detection result from a detection mechanism which detects the size of the paper sheet in accordance with the data associated with a size of the paper sheet on which the information is recorded from the data controller. The LCD display displays the size of the paper sheet when a manual feed switch detect that the paper sheet is manually fed.

When a monochromatic copy mode is to be executed, a control section sets a read mode in a scanner section so as to enable the scanner section to read an image at high speed by means of only a line sensor K, sets in an image processing section an image process that can print monochromatic image information, which is sent from the scanner section, with a single black color in the printer section, and sets in the printer section a monochromatic print mode that can print a black image at high speed, thereby controlling a monochromatic copy operation.

An image forming apparatus according to an embodiment of the invention reads an original by mechanically moving an axial light source in a subscanning direction perpendicular to the axis. The image forming apparatus includes: a sensor whose resolution in a main scanning direction parallel to the axis of the axial light source is higher than a designated resolution; a controller that controls the driving speed of the axial light source so that the resolution in the subscanning direction is higher than the designated resolution; an original-image-data generating unit that generates original image data with a resolution higher than the designated resolution in response to the output from the sensor; and an image reducing unit that generates reduced pixels fewer than a specified number of pixels in the original image data to generate a reduced image with a resolution equal to the designated resolution.
摘要:
A method and apparatus of forming an image includes reading an original with a first resolution. An original is read with a second resolution which is different from said first resolution. The image information read with the first resolution and the second resolution is converted into image information of a third resolution for image forming. An image is formed with the third resolution based on the image information converted by the conversion.
摘要:
An embodiment of a document processing apparatus that has a function of correcting image scanning resolution according to the present invention includes a first carriage mounted with a first reflector that reflects reflected light from a document fixed on an original placing glass plate in a predetermined direction and a second carriage mounted with a second reflector that changes a direction of incident light from the first reflector by 180°. A correction distance from a default position of the second carriage with which predetermined resolution is obtained in plural scanning positions of the first carriage is calculated. An operation of the second carriage is controlled based on the correction distance obtained.
摘要:
Methods and apparatus for color signal compensation are disclosed. A quality of one type of signal is enhanced using a second type of signal, wherein the second type of signal has a higher quality than that of the unenhanced first type of signal. This may be used in an image forming apparatus for scanning a color image, and using higher-resolution monochrome signals to enhance the resolution of lower-resolution color signals.
