摘要： A gray balance control system for reproducing original images. An optical signal is separated into a plurality of separated color signals, gray balance conversion data for each of the colors of the separated color signals is stored in a memory circuit, and an equivalent neutral density conversion is performed on the plurality of separated color signals by converting the color signals to gray balanced color signals in accordance with the gray balance conversion data. Finally, the gray balanced color signals are converted into print signals for coloring materials.

摘要： A reduction/enlargement processing system for an image processing apparatus of the type in which a line sensor is moved in a secondary scan direction while an image on an original is read by the line sensor in a main scan direction, comprising, line buffers for retaining image data for two lines, an interpolation processing circuit for applying a 2-point interpolation to the image data when the image data is written into or read out of the buffers, and a control circuit for controlling the writing data to and read data from the buffers and the interpolation circuit. Further, selectors are provided on the data input side and the data output side, and on the buffer side. The interpolation circuit is connected between the selectors. The line buffers are alternately selected for the read/write of image data. With use of the selectors, the 2-point interpolation may be applied to the image data or the image data may be directly processed. This provides a simple data processing that is performed in accordance with the reduction/enlargement mode.
摘要翻译：一种用于图像处理装置的缩小/放大处理系统，其中线传感器在副扫描方向上移动，同时原稿上的图像在主扫描方向上被线传感器读取，包括用于保持的行缓冲器用于两行的图像数据，用于当图像数据被写入或从缓冲器读出时对图像数据进行2点插值的内插处理电路，以及控制电路，用于控制向缓冲器和内插电路。此外，选择器设置在数据输入侧和数据输出侧以及缓冲器一侧。内插电路连接在选择器之间。交替选择行缓冲器用于图像数据的读/写。利用选择器，可以将2点插值应用于图像数据，或者可以直接处理图像数据。这提供了根据缩小/放大模式执行的简单数据处理。
