摘要： A ring buffer is provided in the data holding section A3 of a data processing section 100A. A master-slave relationship between a plurality of data processing sections 100A, 100B is set. A data output synchronizing signal of the data processing section 100A acting as a master is supplied to the data processing section 100B acting as a slave. This makes it possible to synchronize the output data of the individual data processing sections, while suppressing the memory cost. Input connection terminals (A1) take in object data, an object data enable signal (INHDEN) from the outside, and an object read clock (IMCLK) from the outside. A data holding section (A3) stores object data on the basis of an internal clock. A synchronizing circuit (A4) reads the stored object data on the basis of INHDEN and IMCLK. An output connection terminal (A2) outputs output object data, INHDEN, and an internal clock equivalent to IMCLK to the outside.

摘要： In a color image forming apparatus in which images of a plurality of element colors are sequentially transferred to form a color image, there are provided a plurality of RAM/register units with respect to one image processing unit. Control information is previously stored in the RAM/register units, so that the switching of the element color to be transferred is achieved by switching the RAM/register units, not by rewriting the contents of the RAM/register unit. Thereby, simplification of constitution and high-speed printing can be achieved.
摘要翻译：在顺序地传送多个元素颜色的图像以形成彩色图像的彩色图像形成装置中，相对于一个图像处理单元设置有多个RAM /寄存器单元。控制信息预先存储在RAM /寄存器单元中，以便通过切换RAM /寄存器单元而不是通过重写RAM /寄存器单元的内容来实现要传送的元件颜色的切换。由此，可以实现构造和高速打印的简化。

摘要： If a CPU is informed that “1200×1200 dpi” is selected from an input unit, the CPU switches a normal 8-bit RIP process with 600×600 dpi to a 1-bit RIP process with 1200×1200 dpi. Image data, which has become 1-bit data with 1200 dpi, is stored in a page memory. A pixel packing process unit executes (2×2) packing when the image data stored in the page memory is to be output from the page memory. The packed Y color image data is restored, without delay, to a normal pixel unit in a pixel division unit. The packed M color image data is restored, with a delay in a delay memory, to a normal pixel unit in the pixel division unit. The packed C color image data is restored, with a delay in the delay memory, to a normal pixel unit in the pixel division unit. The packed K color image data is restored, with a delay in the delay memory, to a normal pixel unit in the pixel division unit.
摘要翻译：如果CPU从输入单元中选择“1200x1200 dpi”，CPU将以600x600 dpi的正常8位RIP进程切换到1200x1200 dpi的1位RIP进程。已经成为具有1200dpi的1位数据的图像数据被存储在页存储器中。当从页存储器输出存储在页存储器中的图像数据时，像素打印处理单元执行（2x2）打包。打包的Y彩色图像数据没有延迟地恢复到像素分割单元中的正常像素单元。打包的M色图像数据在延迟存储器中被延迟到像素分割单元中的正常像素单元。打包的C彩色图像数据在延迟存储器中被延迟到像素分割单元中的正常像素单元。打包的K色图像数据在延迟存储器中被延迟到像素分割单元中的正常像素单元。
