摘要： An image reading system for reading color information on an original picture, the reading system comprising a scanning section for optically scanning the original picture and a color chip having a predetermined density value and a reading section for receiving reflection or transmission light obtained with the scanning section optically scanning the original picture and the color chip and for converting the reflection or transmission light into the corresponding electric signal. The reading system is arranged to optically read a density of the color chip so as to constitute a densitometer with the read density of the color chip being adjusted to be substantially coincident with the predetermined density and to measure densities of highlight and shadow points on the original picture by means of the densitometer. Further, the reading system corrects density values, which are designated by an operator, on the basis of the measured densities so that a balance between a plurality of colors obtained through color separations of the highlight and shadow points is kept and to perform a coordination between the read density and a density of the original picture with the read densities of the highlight and shadow points being adjusted to be coincident with the corrected densities.

摘要： Light beams scans patterns of a subject copy, being reflected therefrom, and being converted into pulsating electrical signals. Color borders between two different colored patterns are detected based on the pulsating signals. On the other hand, a color of a predetermined scanned line following each of the color borders is sensed for determining the sensed color as a color between the adjacent color borders.

摘要： A color correction method applicable to a digital processing type of color copier, whereby a set of color patches of respectively different sample colors is printed using a set of printing data values, the color patches are then scanned and analyzed to obtain color patch input data values by the color copier, and each of all of the possible input color data values that can be produced by the scanner/analyzer section of the color copier is then related to one of the color patch input data values which is closest thereto in a 3-dimensional color space. Each of these possible input color data values is thereby related to an appropriate color printing value, whereby a color correction table can be generated which provides correction accuracy that is independent of non-linearity of color printing characteristics.

摘要： A correspondence relation between a structure of a bi-level pattern A and a structure of a bi-level pattern B is statistically learned by use of a learning high-density image. The bi-level pattern A forms a partial region of a low-density character and line image except a screened dot image. The bi-level pattern B forms a corresponding partial region of a desired high-density image. A judgement is made as to whether the low-density image is equal to or different from a screened dot image. Reference pixels are selected from the partial region of the low-density image. The low-density bi-level pattern A is converted into the high-density bi-level pattern B on the basis of a result of the learning by use of the selected reference pixels when the low-density image is different from a screened dot image. A pixel of the low-density image is repeated to convert the low-density image into the high-density image when the low-density image is equal to a screend dot image.
