    • An apparatus and a method for efficiently executing correction of false color, such as purple fringe, caused by chromatic aberration and for generating and outputting high-quality image data are provided. A white-saturated pixel is detected from image data, a false-color-pixel detection area is set around the detected white-saturated pixel, and pixels having color corresponding to false color such as purple fringe are detected from the set area. The detected pixels are determined as false-color pixels and correction processing based on the values of the surrounding pixels is performed on the determined false-color pixels. With this configuration, an area of false color such as purple fringe generated in the neighborhood of a white-saturated pixel can be efficiently detected, pixel values can be partially corrected, and high-quality image data can be generated and output without affecting the entire image.
    • 提供了一种用于有效地执行由色差引起的诸如紫色条纹的伪色的校正以及用于生成和输出高质量图像数据的装置和方法。 从图像数据检测出白色饱和的像素,在检测到的白色饱和像素周围设置假色像素检测区域,并且从设定区域检测具有与诸如紫色边缘的假色相对应的颜色的像素。 检测出的像素被确定为假色像素,并且对所确定的假彩色像素执行基于周围像素的值的校正处理。 利用这种配置,可以有效地检测在白色饱和像素附近产生的诸如紫色条纹的假色区域,可以部分地校正像素值,并且可以在不影响整体的情况下产生和输出高质量图像数据 图片。

    • An accurate white balance adjustment process is provided for an image captured in an environment where different color components, such as an ambient light and a flash light are mixed. With respect to image to be captured under a plurality of different types of irradiation light, such as ambient light, and flash light, the image is captured or generated in an environment of single light irradiation. The white balance adjustment according to the parameter set up based on the color component (color temperature) of each type of irradiation light is carried out with respect to the image in each environment of the single light irradiation, so as to synthesize them Furthermore, with respect to the moved portion of the subject itself, the present invention is arranged such that the pixel value is compensated and set up based on adjacent pixel values of the motionless portion, it becomes possible to generate a natural image data with smooth changes between pixels.
    • 为在不同颜色成分(例如环境光和闪光灯)混合的环境中拍摄的图像提供准确的白平衡调整处理。 对于在多种不同类型的照射光(例如环境光和闪光)下捕获的图像,在单次光照射的环境中捕获或产生图像。 根据基于每种照射光的颜色分量(色温)设置的参数的白平衡调整是针对单次光照射的每个环境中的图像进行的,以便合成它们。 此外,对于被摄体本身的移动部分,本发明被布置为使得基于静止部分的相邻像素值来补偿和建立像素值,可以产生具有平滑变化的自然图像数据 像素之间。
