Abstract: A system for self-aligning a raster input scanner in the slow scan direction where, at start of scan, a target having a variable density image is scanned first until a preset target image line is obtained and the position of the scan carriage registered; then from the registered position, the platen is scanned through a predetermined number of scan lines; following this, the carriage is reversed and returned the same number of scan lines where the target is again scanned and the target image line obtained compared with the previous target image line to determined if a valid scan cycle has taken place.

Abstract: Amounts of read position errors in subscanning direction with respect to respective scanning positions of line image sensors, which are provided in parallel with main scanning direction, are found in advance by a number of scanning lines. In actual scanning, output image signals from the line image sensors are delayed, in respective main scanning positions of the output image signals, by respective line numbers corresponding to the respective found amounts of read position errors in the subscanning direction, and are output.

Abstract: An image reading apparatus, an image reading method and a program are provided for favorably correcting color misalignment in a sub-scanning direction of a read signal read by a plurality of line sensors without increasing a circuit scale or processing time. To accomplish this, the image reading apparatus sets, as a reference signal, the read signal that is output from one of the plurality of line sensors, and detects a correlation between the reference signal and each of a plurality of read signals output from line sensors other than the one of the plurality of line sensors of a plurality of lines that are displaced in predetermined line units from a line from which the reference signal is read, and selects a read signal having a high correlation with the reference signal as a read signal from the line of the reference signal.

Abstract: A scanner unit as an image read-out apparatus has a document glass on which a document is placed, an exposure lamp for illuminating the document with light, a CCD line sensor for receiving reflected flight from the document and converting the light to electric signal, first to third mirrors for conducing the reflected light from the document to the CCD sensor and a light condensing lens for allowing the reflected light which is conducted through the first to the third mirrors to condense on the CCD line sensor. In a position away from a document effective area at which the document is set on a document glass a chart is printed or attached to allow diagnosis to be made for the "displacements" of scanner unit's respective constituent elements, that is, optical members such as the exposure lamp, first to third mirrors, lens and CCD line sensor.
