    • The present invention relates to an apparatus and a method for estimating noise in order to solve a problem of improperly judging a texture as a noise. The method for estimating noise of the present invention comprises the steps of: generating an initial noise map for an image signal inputted; generating at least one noise map in accordance with the image signal and a temporal change of continuous image signals; calculating a correlation value between the initial noise map and the noise map; and determining the noise of the image according to the temporal change based on the correlation value.

    • A method and a system for reading out information data in a non-volatile memory without errors are provided to prevent a communication error which is generated when reading out information of CRUM(Customer Replacement Unit Memory) of consumption goods. A first check sum value corresponding to an non-volatile memory information data which is installed in consumption goods, is obtained(10). The first check sum value is confirmed whether same to a second check sum value stored in an image forming device. If the check sum values are same, the non-volatile memory information data stored in the image forming device which is corresponded to the second check sum value, is read out(40).

    • A printing control method and an image printing system using the same are provided to efficiently perform a printing job by enabling a host device to remove an error through control of an image forming device. The host device(100) checks whether the image forming device(200) is a blocking state, incapable of receiving printing data, if the image forming device is a printing state. The host device cancels the blocked printing job of the image forming device if the image forming device is the blocking state. The host device checks the blocking state by asking an operation state from the image forming device, receiving a response, asking whether the image forming device is the blocking state if the response indicates that the image forming device is the printing state, and receiving the response.
    • 提供一种打印控制方法和使用该打印控制方法的图像打印系统,以通过使主机能够通过图像形成装置的控制来消除错误来有效地执行打印作业。 如果图像形成装置是打印状态,则主机装置(100)检查图像形成装置(200)是否是阻挡状态,不能接收打印数据。 如果图像形成装置是阻挡状态,则主机装置取消图像形成装置的封锁打印作业。 主机通过向图像形成装置询问操作状态,如果响应表示图像形成装置处于打印状态,则接收响应,询问图像形成装置是否为阻挡状态,并且接收到响应 。
