    • An object is to carry out color correction in a highly accurate manner on images acquired by various digital cameras and scanners. A color correction apparatus includes a determining unit configured to determine whether or not preprocessing for removing the effect of previously-performed color correction is required for a reference image that is used for a reference of color correction and a color correction target image on which color correction is to be carried out; a preprocessing unit configured to carry out preprocessing on a reference image and a color correction target image that is determined by the determining unit as requiring preprocessing and output a preprocessed image; a color-correction processing unit configured to acquire a reference image or color correction target image that is not preprocessed if the determining unit determines that the reference image or color correction target image does not require preprocessing or to acquire a preprocessed reference image or color correction target image if the determining unit determines that the reference image or color correction target image requires preprocessing, and to correct the color correction target image on the basis of the acquired reference image.
    • 目的是以高精度的方式对由各种数码相机和扫描仪获取的图像进行颜色校正。 颜色校正装置包括:确定单元,被配置为确定用于去除用于颜色校正的参考的参考图像的预先执行的颜色校正的效果的预处理是否需要用于其上的颜色校正的颜色校正目标图像 要进行; 预处理单元,被配置为对参考图像执行预处理,并且所述颜色校正目标图像由所述确定单元确定为需要预处理并输出预处理图像; 颜色校正处理单元,被配置为如果所述确定单元确定所述参考图像或颜色校正目标图像不需要预处理或获取预处理的参考图像或颜色校正目标,则获取未被预处理的参考图像或颜色校正目标图像 如果确定单元确定参考图像或颜色校正目标图像需要预处理,并且基于所获取的参考图像来校正颜色校正目标图像。

    • An evaporative fuel control system for an internal combustion engine having a throttle valve includes a canister for adsorbing evaporative fuel generated in the fuel tank, a purging passage for purging evaporative fuel into the intake system of the engine, and a purge control valve for controlling a flow rate of the evaporative fuel to be purged into the intake system through the purging passage. An ECU sets an air-fuel ratio correction coefficient applied in air-fuel ratio feedback control, based on the concentration of a specific component in exhaust gases emitted from the engine, calculates a first learned value of the air-fuel ratio correction coefficient during execution of the air-fuel ratio feedback control, and controls the purge control valve such that the flow rate of the evaporative fuel is changed according to the calculated first learned value. A second learned value of the air-fuel ratio correction coefficient suitable for the transient operating condition of the engine is calculated. When the engine is in a transient operating condition, the first learned value is set to the second learned value.
    • 用于具有节流阀的内燃机的蒸发燃料控制系统包括用于吸收在燃料箱中产生的蒸发燃料的罐,用于将蒸发燃料吹入发动机的进气系统的清洗通道,以及用于控制发动机的排气控制阀 通过清洗通道将要吹扫进入系统的蒸发燃料的流量。 ECU根据从发动机排出的废气中的特定成分的浓度,设定在空燃比反馈控制中使用的空燃比校正系数,计算执行中的空燃比校正系数的第一学习值 并且控制净化控制阀,使得蒸发燃料的流量根据计算出的第一学习值而改变。 计算适合于发动机的暂态运行状态的空燃比校正系数的第二学习值。 当发动机处于瞬态运行状态时,将第一学习值设定为第二学习值。
