    • A variation in a discharge characteristic among respective nozzles of an inkjet printer is corrected. A color correction table generating section 48, (1) based upon error information (nozzle classes) representing errors of color values of outputs due to errors in ink weights for three types of dots (large, middle, and small) respectively for multiple types of ink colors (CMYK), determines a second correspondence between tone values of color-converted image data and combinations of respective recording ratios of the three types of dots so that the error is approximately zero, and (2) determines combinations of a first tone value and a second tone value so that a total ink discharge quantity according to a first correspondence (SML table recording section 44a) of the first tone value representing color-converted image data and a total ink discharge quantity according to a second correspondence of the second tone value representing the color-converted image data are approximately equal. The color correction section 43b outputs a first tone value upon image data in CMYK being considered as a second tone value, and provides an SML dot number determining section 44b with the output as a tone value of the image data in CMYK.
    • 校正喷墨打印机的各喷嘴之间的放电特性的变化。 颜色校正表生成部分48,(1)基于错误信息(喷嘴类别),分别表示由于三种类型的点(大,中,小)的油墨重量的误差而导致的输出的颜色值的误差 墨水颜色(CMYK)确定颜色转换图像数据的色调值与三种类型的点的各个记录比率的组合之间的第二对应关系,使得误差近似为零,以及(2)确定第一色调值 和第二色调值,使得根据第一对应关系(SML表记录部分44a)的总墨水排出量与表示色彩转换图像数据的第一色调值和总排墨量根据第二对应关系 表示颜色转换图像数据的色调值近似相等。 颜色校正部分43b将CMYK中被认为是第二色调值的图像数据输出第一色调值,并将SML点数确定部分44b作为CMYK中的图像数据的色调值提供。

    • When it has become necessary to reset color adjusting ID for the printer 20 because of the replacement of component parts or other causes, even in an environment where the printing condition that had been adopted for setting the ID in the past cannot be recreated, it is easy to calculate the ID of the equivalent value as those that would have been calculated if the printing condition that had been adopted for setting the ID in the past can be made available by using the color component conversion function. As a result, it will be no longer necessary to maintain materials and equipment in a good and unified state in the production site of products or at places where after-sales services are rendered.
    • 当由于更换部件或其他原因而需要重置打印机20的颜色调整ID时,即使在过去用于设置ID的打印条件不能重新创建的环境中,即使是 如果通过使用颜色分量转换功能可以使用过去用于设置ID的打印条件可以计算出等效值的ID。 因此,不再需要在产品生产现场或提供售后服务的地点维护材料和设备处于良好统一的状态。

    • In a still image shooting mode, when a user does not specify a position of an AF frame, an AF process is performed for an AF region of a comparatively large range whose center is in a center of a shooting frame. When the user taps on any position in an EVF area, a touch panel superimposed on a display detects its coordinates. An AF region smaller than the AF region when the user does not specify the position of the AF frame is arranged so that a center of the AF frame is on the coordinates. The AF process is carried out for the smaller AF region. When the user taps on the EVF area 221 twice at a short predetermined interval, a PDA returns the AF region to a state where the position of the AF frame 261 is not specified by the user.
    • 在静止图像拍摄模式中,当用户未指定AF框的位置时,对于其中心在拍摄框的中心的较大范围的AF区域进行AF处理。 当用户点击EVF区域中的任何位置时,叠加在显示器上的触摸面板检测其坐标。 当用户没有指定AF框的位置时,AF区域小于AF区域被布置成使得AF框的中心在坐标上。 对于较小的AF区域进行AF处理。 当用户以短的预定间隔敲击EVF区域221两次时,PDA将AF区域返回到AF框261的位置未被用户指定的状态。
