摘要： A forming unit forms a latent image of input image data. A counter counts number of times of forming the latent image in a sub-scanning direction, in which an upper limit of the number of times is set. A first control unit controls the forming unit to form the latent image based on the upper limit. A determining unit determines whether a latent image forming is performed by the forming unit exceeding the upper limit. When the determining unit determines that the latent image forming is performed exceeding the upper limit, a second control unit controls, the forming unit to continue to form the latent image.

摘要： Various systems, methods, and programs embodied in a computer readable medium for determining color separation are provided. In one representative embodiment, a method is provided that comprises specifying a number of nodes along a number of ramps in a predefined color conversion space in a computer system. A maximum possible toner deposit is associated with each of these nodes. In addition, a maximum toner limit is specified for each one of the nodes along the ramps in the computer system. Each of the maximum toner limits is less than the maximum possible toner deposit. In addition, a color separation is determined for each of the nodes along the ramps in the computer system. Each of the color separations specifies up to a maximum amount of toner equaling a corresponding one of the maximum toner limits.

摘要： A controller for a four-drum printer eliminates a need for an expensive inter-drum delay memory, which has been conventionally used, to print an RGB image and allows a multifunction machine, printer, and the like to be provided at low cost. An image ring interface reads an image data containing the same tile, which is stored in a tile pattern in a RAM, four times with a delay corresponding to a delay (10 lines of tiles) of image formation between image forming sections, and sequentially transfers the image data to four image output interfaces.

摘要： To correct the distance between respective drums and supply image data, an image processing system using a 4-drum type color image forming apparatus requires a large-capacity image memory for temporarily storing transferred image data, and is inevitably expensive. In this invention, image data of four colors isochronously transferred via a high-speed serial interface such as an IEEE 1394 interface are respectively supplied to image processing units and image forming units via delay memories. Therefore, the time difference required for the print sheet to reach each drum can be corrected in each image forming unit to appropriately form an image at a high speed and low cost.

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。

摘要： A set pattern image with no displacement is recorded onto recording paper. In this set pattern image, the centers of auxiliary patterns are displaced in an auxiliary scan direction off a referential straight line passing through the centers of primary patterns. The image forming apparatus causes the set pattern image to be read, measures the displacements of the auxiliary patterns in the auxiliary scan direction off the referential straight line, and compensates for the displacements, such as by adjusting writing timings in the auxiliary scan direction so that the displacements become zero.
