    • When the printer 10 receives a request signal from one of the administrative computer G and the computers 20 indicating that the user has used the mouse 53 to click the “Edit” button displayed on the CRT monitor 55 (S4), then the printer 10 transmits data for the edit wizard 201 for modifying setting items displayed in the print function settings wizard 202 to the administrative computer G or the computer 20 corresponding to the ID data set attached to the request signal. The user uses the mouse 53 to click on either “Display on” or “Display off” next to each setting item in the edit wizard 201 displayed on the CRT monitor 55 (S6), enabling the user to re-edit setting items displayed in the print function settings wizard 202 (S7-S13).

    • A printer is capable of generating a plurality of different measurement patch groups, each group being configured of a plurality of measurement patches having different densities. The printer determines the overall density level of the image by examining image data. Based on the determined overall density level of the image, the printer determines patch densities for the measurement patches so that the patch densities become darker as the overall density level of the image becomes darker and become lighter as the overall density level of the image becomes lighter. When the measurement patches are generated based on the determined patch densities, a density sensor is controlled to measure the densities in the measurement patches. A correction table is created based on the measured results. The printer corrects densities in the image data based on the correction table, and prints the image on a paper based on the corrected image data.
    • 打印机能够生成多个不同的测量贴片组,每个组由具有不同密度的多个测量贴片构成。 打印机通过检查图像数据来确定图像的总体浓度级别。 基于确定的图像的总体密度水平,打印机确定测量贴片的贴片密度,使得随着图像的总体密度水平变得更暗,图像的整体浓度水平变得更暗并变得更亮,贴片密度变得更暗 。 当基于确定的贴片密度产生测量贴片时,控制密度传感器以测量测量贴片中的密度。 基于测量结果创建校正表。 打印机基于校正表来校正图像数据中的浓度,并且基于校正的图像数据将图像打印在纸张上。

    • It is an object to provide an operation control apparatus and an operation control method which allow operation of a control object without causing adverse affect on the operational condition of the control object, even when a deviation of a real system from a model (model error) arises. The operation control method employable in the control apparatus controls a control object by calculating operation amount to maximize or minimize an evaluation value obtained from a control deviation of the control object from a target value. The operation control method includes the steps of: establishing a model for simulating a property of the control object; calculating operation amount to maximize or minimize an evaluation value based on a control deviation of the model as a target; calculating an evaluation value based on a control deviation in controlling the control object by the operation amount; and determining an operation amount change width defined by a difference between current step operation amount and next step operation amount, based on the deviation of the control object from the model in the evaluation value of the control deviation.
    • 本发明的目的是提供一种操作控制装置和操作控制方法,其允许控制对象的操作而不会对控制对象的操作条件造成不利影响,即使实际系统与模型的偏差(模型误差) 出现。 控制装置中可以使用的操作控制方法通过计算操作量来控制控制对象,以使从控制对象的控制偏差获得的评估值与目标值最大化或最小化。 操作控制方法包括以下步骤:建立模拟控制对象的属性的模型; 计算操作量以使得基于作为目标的模型的控制偏差来最大化或最小化评估值; 基于通过所述操作量控制所述控制对象的控制偏差来计算评估值; 并且根据控制偏差的评价值中的控制对象与模型的偏差,确定由当前步骤操作量与下一步操作量之间的差定义的操作量变化宽度。

    • An interpreter portion obtains page description language data that includes image data of an image source and image-size specifying data of both the image source and a device image. The interpreter portion generates intermediate data based on the image data of the image source and the image-size specifying data. If the image-size specifying data specifies enlargement from the image source to the device image, the interpreter portion generates the intermediate data that includes intermediate image data that is the same data as the image source data and enlargement ratio data. A rasterize portion generates print data in an output memory based on the intermediate data.

    • A projection display apparatus is provided which offers improved contrast while smoothly controlling the amount of light, with a simple structure and without deterioration of lifetime due to the heat of the light from a light source. This projection display apparatus includes a light valve, a light source for emitting light to the light valve, an integrator lens disposed on the optical path of the light propagating from the light source to the light valve, for making uniform the illuminance distribution of the light from the light source, and a shutter mechanism disposed on the light path, for controlling the amount of light that illuminates the light valve. The shutter mechanism has a pair of light-blocking members having cuts formed in their respective protruding sides to regulate the passage of light, and the pair of light-blocking members are moved straight to protrude/retract on the optical path, perpendicularly to the optical path from both sides of the optical path, so as to control the amount of the light according to the extent of their protrusion on the optical path.
