摘要： An image reading apparatus includes a front-side reader, which includes a white LED configured to irradiate an original with light and a CMOS sensor configured to receive light that is reflected by the original. The front-side reader is configured to generate read data that represents a luminance value of an image on the original from the result of receiving light with the CMOS sensor. The image reading apparatus stores, in a non-volatile memory, a condition for determining whether there is a sub-scanning color shift, and uses a sub-scanning color shift detector to determine whether there is a sub-scanning color shift based on the read data obtained from the front-side reader and the condition stored in the non-volatile memory. When there is a sub-scanning color shift, the image reading apparatus corrects the sub-scanning color shift by correcting the read data with a color shift corrector.

摘要： 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.

摘要： An image data sequencing method for a memory unit inside an optical scanning device. The image data sequencing method is particularly suitable for scanning a line of pixels with each pixel comprising a plurality of primary colors. The image data sequencing method involves scanning a line of pixels to obtain the data for a primary or secondary color. The pixels within the scan line are subdivided into groups. A storage space is reserved both before and after the address space inside the memory unit for holding the scanned primary or secondary color data so that all the primary or secondary color data constituting a pixel are in a fixed sequence next to each other inside the memory unit. When all the primary or secondary color data of pixels within a group are secured, the group of data is released from the memory unit.

摘要： In a method of scanning an image on an original, an optical sensor including sensor elements for each of a number of basic colors is used to generate pixel values of rows of pixels of the scanned image. The sensor elements are used to generate grey scale pixel values representing different parts of the image. A first sensor element for each of the basic colors is used to generate pixel values of odd pixels of rows on the original, and a second sensor element for each of the basic colors is used to generate pixel values of even pixels of rows of the original. Each grey scale pixel value is generated mainly on the basis of a pixel value of at least one of the first sensor elements and a pixel value of at least one of the second sensor elements for adjacent pixels.

摘要： A four-line CCD sensor is structured by line sensors R, G, B in which color fillers are respectively disposed on surfaces of light receiving elements, and a line sensor BK at which no color filter is disposed. Amplitudes of signals which are outputted from the line sensors R, G, B at a time of reading a color document, and an amplitude of a signal which is outputted from the line sensor BK at a time of reading a monochrome document are adjusted so as to be substantially equal to one another. In a case in which a color document is read, outputs of the line sensors R, G, B are selectively provided, and in a case in which a monochrome document is read, output of the line sensor BK is selectively provided.

摘要： An image processing apparatus performs a first edge determination to determine whether each pixel is an edge of a black character or a thin black line based on a pixel signal of a predetermined color in each pixel included in multi-valued image data. The image processing apparatus determines whether to achromatize a pixel signal of each pixel included in the multi-valued image data based on a result of the first edge determination, and achromatizes a pixel determined to be achromatized. The image processing apparatus performs a second edge determination for determining whether each pixel is an edge based on a pixel signal of a color different from the predetermined color in each pixel included in the multi-valued image data. The image processing apparatus corrects the multi-valued image data based on a result of the second edge determination after completing achromatization of the pixel determined to be achromatized.

摘要： An apparatus for correcting a scanned image includes a delay circuit configured to delay first image data by a delay amount corresponding to an integer multiple of a line interval, an interpolation circuit configured to perform an interpolation computation responsive to interpolation coefficients with respect to two or more lines included in the first image data delayed by the delay circuit, and a control circuit configured to set the delay amount to the delay circuit and the interpolation coefficients to the interpolation circuit, wherein the control circuit is configured to set the delay amount to an amount corresponding to integer m smaller than integer n and set the interpolation coefficients such that the interpolation computation becomes equivalent to a computation introducing a delay equal to n−m lines if an interval between the first image data and second image data is n times the line interval.
