    摘要： A color image processing apparatus comprises a printer for printing an image corresponding to an original image scanned by an scanner. An image memory is provided into which signals from the color scanner respectively corresponding to plural colors are written and from which signals to be transmitted to the printer are read. The image memory is arranged such that a signal for a writing operation and a signal for a reading operation are substantially simultaneously input. A memory control unit addresses the image memory in either the writing operation or the reading operation. The memory control unit comprises a writing address counter, a reading address counter and a control means. The control means controls the writing address counter and the reading address counter such that image data is read from the image memory before the writing of the image data into the memory is completed.

    摘要： An image reading apparatus such as a color copying apparatus has a plurality of sensing CCD chips for converting an image of an object into an electrical signal, each sensing CCD chip having a plurality of sensing elements. The apparatus also has a circuit for converting the electrical signal into digital data. A first adjusting circuit is provided for conducting either an operation for obtaining level matching of the electrical signal converted by the sensing chips, or an operation for controlling the gain of the electrical signal converted by the sensing chips. The apparatus further has a second adjusting circuit for effecting compensation for fluctuation of characteristics of the sensing elements of the sensing chips, by making use of the digital data converted by the converting circuit, the second adjusting circuit being adapted for effecting the compensation on the basis of electrical signals which are produced as a result of conversion by the sensing chips from two objects having different levels of density from each other, such as white and black levels. An analog-to-digital converter may also be provided to convert analog data into digital data. In that case, first adjusting means will adjust the analog data discretely, through a step smaller than the quantizing step used in the A/D conversion, and a second adjusting means may preferably further adjust the analog data in accordance with digital data obtained through the A/D conversion.
