摘要： A matrix unit receives a luminance signal L* for a uniform color space and two color difference signals a* and b*. Then, when a control signal has given instructions for a mono-color editing operation, the matrix means outputs only the luminance signal L* out of the picture image data fed into it, and, when a control signal is given otherwise, the matrix means generates and outputs toner color signals for the colors Y, M, C, and K. A multiplying unit multiplies with a prescribed coefficient the picture image data which are output from the matrix unit, and the multiplying unit multiplies the picture image data with a coefficient for permitting the toner signal output from the matrix unit to pass through in case the control signal has not given any instructions for any mono-color editing operation, and multiplies the input luminance signal L* with four coefficients corresponding to the color as instructed by the control signal and generate four toner color signals for Y, M, C, and K. The coefficients have the data form representing the coverage of the toner colors, Y, M, C, and K.

摘要： A ground detection means 10 for detecting the ground level of a document and a data correction means 11 for calculating correction data based on the detected ground level are provided. The ground level of the document is detected by prescanning and the correction data is calculated therefrom so that parameters of color conversion means 2, 3 are changed by the correction data. The correction data is set by approximating the detected ground level with a linear function. As a result of the above construction, the correction data is generated easily to thereby remove ground fog and exclude back-side images of the document. In addition, if the ground level is detected by a lightness signal L* and corrected by the lightness signal L* or a color-separated signal BGR, the correction can be achieved by correcting the parameters of a matrix that converts the color-separated signals B, G, R to a system value (L*a*b*) signal.

摘要： An image processing apparatus has an original read unit for reading an image on an original document by a prescan and a copy scan, an image data processing unit for converting original image signals into digital image data signals and for processing the digital image data signals, and an output unit for outputting processed image data. The image processing apparatus further comprises an original detecting unit (3) for reading coordinates data on the original in a prescan mode, and enlargement/reduction processing units (2, 4 to 9) which store the image data read in a copy scan mode into a memory, execute the enlargement/reduction in accordance with the stored image data, whereby the enlargement/reduction processing units (2, 4 to 9) carry out the frame-erasure process by using the original coordinates data. Thereby, an image processing apparatus in which an area to be erased can be flexibly changed, and undesired spaces, which otherwise will be caused by the frame erasure processing, are not created even in a repeat processing or an enlargement/repeat processing.
