    • There is provided an image forming system that are capable of preventing a user or operator from forgetting to carry out a maintenance operation based on required sub-maintenance items after execution of a maintenance operation based on an associated maintenance item, such as component replacement, cleaning, or adjustment. A table of maintenance items and sub-maintenance items associated with respective ones of the maintenance items is stored in a ROM. When a CPU determines that a maintenance operation based on a selected one of the maintenance items has been completed, the CPU determines whether or not there is any sub-maintenance item associated with the selected maintenance item, by referring to the table. When it is determined that there is one or more sub-maintenance items associated with the selected maintenance item, a CPU provides control to display the sub-maintenance item or items in an operating/display unit.
    • 提供了一种图像形成系统,其能够基于相关联的维护项目(诸如部件更换,清洁)而在执行维护操作之后基于所需的子维护项目而忘记使用者或操作者进行维护操作 ,或调整。 与各个维护项目相关联的维护项目和子维护项目的表存储在ROM中。 当CPU确定基于所选择的一个维护项目的维护操作已经完成时,CPU通过参考该表来确定是否存在与所选择的维护项目相关联的任何子维护项目。 当确定存在与所选择的维护项目相关联的一个或多个子维护项目时,CPU提供控制以在操作/显示单元中显示子维护项目。

    • A state-of-eye distinguishing means calculates a feature value that represents a state of an eye, for an eye-area based on pixel data of pixels that constitute the eye-area. A threshold value setting means calculates a first threshold value representing a feature value at a first transition point from an open state to a closed state and a second threshold value representing a feature value at a second transition point from the closed state to the open state, based on a feature value calculated for a targeted eye when the targeted eye is open. A blinking state detection means detects the blinking state of the eye corresponding to the eye-area, by sequentially comparing feature values which are sequentially calculated for a series of frame images by the state-of-eye distinguishing means with one of the first threshold value and the second threshold value.
    • 眼睛辨别手段基于构成眼睛区域的像素的像素数据,计算表示眼睛的状态的特征量,对于眼睛区域。 阈值设定装置计算表示从打开状态到关闭状态的第一转变点处的特征量的第一阈值和表示从关闭状态到打开状态的第二转变点的特征值的第二阈值, 基于当目标眼睛打开时针对目标眼睛计算的特征值。 闪烁状态检测装置通过将通过眼睛辨别装置依次计算的一系列帧图像的特征值与第一阈值之一顺序地比较来检测与眼睛区域相对应的眼睛的闪烁状态 和第二阈值。
