    • In an image forming apparatus for forming an ordinary copy or a tonality image for an original image for a printing press, original image data is divided into data within a predetermined area and that outside the area, and pixel density within the area is subjected to a density conversion in accordance with screen half-toning information which will increase density information toward the approximate center of these pixels, by way of example. The original image data or the density-converted image data is converted into a binary-coded signal conforming to the density, and an output image is formed in accordance therewith. Preferably, plural types of non-linear correction tables are provided and a tone-conversion is performed selecting an appropriate correction table for each pixel, or for each line, of the density-converted image data. Preferably, the original image data is binary coded by a pattern signal having a long period, and the density-converted image data is binary coded by a pattern signal having a short period. The foregoing is applied to color-separated image data of each color. Preferably, the image data is divided, in accordance with color, into predetermined areas having the same or a different number of pixels, or into predetermined areas having a planar phase which differs for each color, and a screen angle is applied thereto.
    • 在用于形成用于印刷机的原始图像的普通复印件或调色剂图像的图像形成装置中,原始图像数据被划分为预定区域内的区域内的数据,并且区域内的像素密度经受 根据将通过示例将密度信息朝向这些像素的近似中心增加的屏幕半色调信息进行密度转换。 原始图像数据或密度转换图像数据被转换为符合密度的二进制编码信号,并且根据其形成输出图像。 优选地,提供多种类型的非线性校正表,并且对密度转换图像数据的每个像素或每行选择适当的校正表,并进行色调转换。 优选地,原始图像数据由具有长周期的图案信号二进制编码,并且密度转换的图像数据由具有短周期的图案信号进行二进制编码。 上述内容适用于每种颜色的分色图像数据。 优选地,根据颜色将图像数据划分为具有相同或不同数量像素的预定区域,或划分成具有对于每种颜色不同的平面相位的预定区域,并且对其施加屏幕角度。

    • A storage system comprises a second NAS storage apparatus and a third NAS storage apparatus for migrating an object managed by a first NAS storage apparatus. The second NAS storage apparatus comprises a processor and a storage medium, which is able to store data. The processor of the second NAS storage apparatus, with respect to an object for which a migration from the first NAS storage apparatus has started, stores path information of the object in the first NAS storage apparatus after including the path information in object management information, in the storage medium prior to migrating the object entity to the third NAS storage apparatus. Also, the processor, after receiving the object entity from the first NAS storage apparatus and migrating the object entity to the third NAS storage apparatus, stores the third NAS storage apparatus path information to the object entity in the object management information, and reflects the management information in the third NAS storage apparatus.
    • 存储系统包括第二NAS存储装置和用于迁移由第一NAS存储装置管理的对象的第三NAS存储装置。 第二NAS存储装置包括能够存储数据的处理器和存储介质。 第二NAS存储装置的处理器相对于从第一NAS存储装置的迁移开始的对象,在将对象管理信息中包含路径信息之后,存储在第一NAS存储装置中的对象的路径信息, 在将对象实体迁移到第三NAS存储装置之前的存储介质。 此外,处理器在从第一NAS存储装置接收到对象实体并将对象实体迁移到第三NAS存储装置之后,在对象管理信息中将第三NAS存储装置路径信息存储到对象实体,并且反映管理 第三NAS存储装置中的信息。

    • A controller works with a measure of temperature of ink at a temperature sensor within a first temperature range to have an inkjet head propel out droplets of ink at a first discharge speed for formation of images, and with a measure of temperature of ink at the temperature sensor within a second temperature range lower than the first temperature range to have the inkjet head propel out droplets of ink at a second discharge speed greater than the first discharge speed for formation of images, and the controller determines that end regions of a frame of images to be formed in regions at transfer-longitudinal ends of a sheet to be transferred in a sheet transfer system have a print ratio within a prescribed range, to execute formation of images.
    • 控制器利用在第一温度范围内的温度传感器处的墨水的温度测量,以使得喷墨头以第一排出速度推动油墨滴形成图像,并且在温度下测量墨水的温度 传感器在低于第一温度范围的第二温度范围内,以使得喷墨头以大于用于形成图像的第一放电速度的第二排出速度推进墨滴,并且控制器确定图像帧的末端区域 要在纸张传送系统中要传送的纸张的转印纵向端部的区域中形成具有在规定范围内的打印率,以执行图像的形成。
