摘要： In a method and an apparatus for reading a color image wherein the color image is illuminated and scanned by light from a plurality of light sources having different spectral properties to read the color image on the basis of the reflected light therefrom, at least one light source of the light sources is kept turned on during the scanning operation of the color image, thereby eliminating any problems resulting from its after-glow; and at least one light source of the light sources other than that kept turned on is repeatedly turned on and off with a period corresponding to the period of the scanning operation so as to project the light from the single and plural light sources selected from the light sources, at least once respectively, upon the scanned portions of the color image. The color image is read by detecting colors on the scanned portions of the color image on the basis of levels of the light reflected from the color image. A variety of colors may be detected by the present invention including red, blue, black and cyan. In addition, the present invention also teaches the use of color filters to eliminate the potential after-glow effect of color fluorescent lamps.

摘要： A picture image position setting apparatus having a linear reading element for obtaining picture information by scanning an original document successively line after line. A position designating cursor is attached slidably in a main scanning direction on a platen at a front end or a rear end portion of an original document scanning region on the platen. The position designating cursor is arranged to be sensed by the linear reading element to distinguish it from other scanned portions. A circuit converts picture image information with respect to the position designating which has been read into positional information in the main scanning direction.

摘要： A method and apparatus for correcting the photoelectric converter of a document reading unit for non-linearities produced by the optics of the system. A test document having no image data thereon is scanned to produce a shade correction signal which is subjected to A/D conversion and stored in a memory. In binary-encoding the picture data of the original, a switch is operated according to the data stored in the memory so as to change a threshold level for the picture signal, whereby digital picture data whose shading has been corrected is obtained. In the case where the picture data of the original are represented by an analog signal, the picture data are also subjected to A/D conversion, and division is carried out with the data stored in the memory being employed as dividends. From the results of such a division, corrected multi-level picture data is obtained.

摘要： A shading correction device has a variable attenuator which is provided in the transmission line of the picture signal after photoelectric conversion by the original reader. For example, at the time of reading all white surface of the original at the beginning of the original scan the information level of each bit of the picture signal, i.e., the level of each picture element, is sequentially attenuated by the variable attenuator. In order to make the level of each picture element uniform, a data on how much attenuation is required, is generated for each picture element and loaded in a memory. The variable attenuator is adapted to be driven and controlled based on the data loaded in the memory at the time of reading the original in the subsequent scan.
