    • In a computer system of the invention, a menu button BT2 ‘Retouching Pre-Process’ clicked to activate a retouching pre-process and a menu button BT3 ‘Retouching Post-Process’ clicked to activate a retouching post-process are vertically downward aligned in a processing menu window MN corresponding to an order of operation procedure. The retouching pre-process includes 16-bit color support image processing options, for example, ‘brightness adjustment’ and ‘contrast adjustment’. The retouching post-process includes 8-bit color support image processing options, for example, ‘unsharp mask’ and ‘light irradiation’. When the operator clicks the menu button BT2 ‘Retouching Pre-process’ to execute any image processing option included in the retouching pre-process after execution of any image processing option included in the retouching post-process with regard to input image data, the computer system opens a message box to notify the operator of prohibition of a return to the retouching pre-process. The computer system thus effectively prevents execution of any image processing option included in the retouching pre-process after execution of any image processing option included in the retouching post-process. This arrangement desirably prevents potential deterioration of the picture quality in a retouching process that includes both the 16-bit color support image processing and the 8-bit color support image processing.
    • 在本发明的计算机系统中,单击激活修饰预处理的菜单按钮BT 2'修饰预处理'和点击激活修饰后处理的菜单按钮BT 3'修饰后处理'垂直向下 在对应于操作顺序的处理菜单窗口MN中对齐。 修饰预处理包括16位颜色支持图像处理选项,例如“亮度调整”和“对比度调整”。 修饰后处理包括8位颜色支持图像处理选项,例如“钝化掩模”和“光照射”。 当操作者在执行包括在对于输入图像数据的修饰后处理中的任何图像处理选项之后,单击菜单按钮BT 2'修饰预处理'以执行包括在修整预处理中的任何图像处理选项时, 计算机系统打开一个消息框,通知运营商禁止返回修复预处理。 因此,计算机系统在执行包括在修整后处理中的任何图像处理选项之后有效地防止执行包括在修饰预处理中的任何图像处理选项。 这种布置期望防止包括16位彩色支持图像处理和8位彩色支持图像处理的修饰处理中的图像质量的潜在恶化。

    • A printer generates a public key with a passphrase containing at least printer position information and a random number by a public key cryptography, and holds this random number. A print client previously acquires the public key from the printer. When transmitting print data to the printer, the print client encrypts the print data in advance with the acquired public key and transmits the encrypted print data as print transmitting data. The printer which has received the print transmitting data generates a private key with a passphrase containing at least printer position information and the held random number by the public key cryptography. The printer then decrypts the received print transmitting data with the private key. Consequently, the security of the print data transmitted from the print client to the printer via a network is ensured.
    • 打印机生成具有至少包含打印机位置信息和通过公共密钥加密的随机数的密码的公钥,并保存该随机数。 打印客户端以前从打印机获取公钥。 当将打印数据发送到打印机时,打印客户端用所获取的公钥预先加密打印数据,并将加密的打印数据作为打印发送数据发送。 已经接收到打印发送数据的打印机生成具有至少包含打印机位置信息和通过公钥密码学保存的随机数的密码的私钥。 然后打印机用私钥对接收到的打印发送数据进行解密。 因此,确保了从打印客户端通过网络传送到打印机的打印数据的安全性。
