    • An imaging apparatus for capturing a moving image performs backlight correction of an image and outputs a natural image. The imaging apparatus electronically captures an image of a subject. An optical system has a light amount adjustment function. An imaging unit reads an optical image of the subject that is formed by the optical system. An A/D converter subjects an output of the imaging unit to A/D conversion. A backlight correction unit converts the tones of an image read by the A/D converter using a conversion characteristic selected differently according to a spatial position and at least increases the luminance level of a dark region of the image. An instruction unit instructs to start backlight correction. A control unit operates the backlight correction unit based on an instruction signal output from the instruction unit, and decreases an exposure light amount of the optical system by a predetermined amount.
    • 用于捕获运动图像的成像装置执行图像的背光校正并输出自然图像。 成像设备以电子方式捕获被摄体的图像。 光学系统具有光量调节功能。 成像单元读取由光学系统形成的被摄体的光学图像。 A / D转换器对成像单元的输出进行A / D转换。 背光校正单元使用根据空间位置不同地选择的转换特性来转换由A / D转换器读取的图像的色调,并且至少增加图像的暗区域的亮度水平。 指令单元指示开始背光校正。 控制单元基于从指示单元输出的指示信号来操作背光校正单元,并且将光学系统的曝光光量减少预定量。

    • An exhaust gas purifying apparatus for an internal combustion engine, including a particulate filter provided in an exhaust passage of the engine; a pressure difference sensor for detecting a pressure difference between upstream and downstream side pressures of the particulate filter; an upstream side passage, which connects the pressure difference sensor and an upstream side with respect to the particulate filter of the exhaust passage; and a downstream side passage, which connects the pressure difference sensor and a downstream side with respect to the particulate filter of the exhaust passage. An exhaust gas flow rate is calculated according to an operating condition of the engine. A characteristic of change in the pressure difference, which is detected by the pressure difference detector and corresponds to a change in the exhaust gas flow rate, is detected. An abnormality of the downstream side passage is determined based on the characteristic of change in the pressure difference.
    • 一种用于内燃机的废气净化装置,包括设置在发动机的排气通道中的颗粒过滤器; 用于检测微粒过滤器的上游侧压力和下游侧压力之间的压力差的压力差传感器; 上游侧通道,其连接压力差传感器和相对于排气通道的微粒过滤器的上游侧; 以及将压差传感器和下游侧相对于排气通路的微粒过滤器连接的下游侧通路。 根据发动机的运转状况来计算废气流量。 检测由压差检测器检测出的并对应于废气流量变化的压力差变化的特征。 基于压力差的变化的特性确定下游侧通路的异常。
