    Abstract: In an image scanning system which includes an image scanning apparatus for scanning an image using a solid-state image sensing element, and an image processing apparatus, the scanned image undergoes image correction. The image scanning apparatus informs the image processing apparatus of image scan characteristic data such as linearity characteristic data unique to itself. The image processing apparatus executes a correction process of an image scanned by the image scanning apparatus using the received image scan characteristic data.

    Abstract: A power control circuit (120) is driven by electric power supplied from a controller (200) as an external device via a cable (150), and controls opening/closure of a switch (104) in accordance with instructions from the controller (200). A DC power supply (105) converts an AC voltage supplied via the switch 104 into a DC voltage and provides it to individual units such as a reader (140).

    Abstract: An image reading apparatus employing a white fluorescent lamp, such as a xenon lamp, as an illuminating unit reduces variations in RGB output level caused by differences in persistence characteristics of phosphors, and also reduces color blurs at document edges in a vertical scanning direction. The lamp is turned on a plurality of times within one storage time of a CCD line sensor, and a lamp-on phase is shifted 180 or 90 degrees for each storage cycle or for each reading line. The lamp is not turned on at a timing when charges are transferred from a photoelectric converting element of the line sensor. Furthermore, a time from the moment when the lamp turns on last within the storage time to the timing at which the charges are transferred is set to be longer than a shortest afterglow time (B or blue) of the fluorescent lamp.

    Abstract: This invention provides an image reading method and apparatus which can prevent a large difference from being produced between the color tones of the read image and the original image. A plurality of signals output from an image sensor (101) are A/D-converted into a plurality of digital signals by A/D conversion circuits (105), a predetermined one of the A/D-converted digital signals is compared with a predetermined reference level by a comparator (108), a low-pass filter (109) removes any high-frequency component from the comparison result, and the output from the low-pass filter (109) is controlled to be input to the A/D conversion circuits (105) as a reference voltage for determining the input range of each A/D conversion circuit (105).
