    • The image processing apparatus includes a gradient calculating part calculating intensity gradient at each pixel in a captured color image, a first color blur determining part determining that a pixel at which the intensity gradient satisfies a color blur condition using a first threshold is a possible color blur pixel, and a second color blur determining part detecting a saturated pixel in the color image, and determining, when a distance between the saturated pixel and the possible color blur pixel is within a second threshold, that the possible color blur pixel is a color blur pixel. The first and second color blur determining parts change the first and second thresholds depending on at least one of luminance and chroma of the possible color blur pixel.
    • 该图像处理装置包括:计算捕获的彩色图像中每个像素处的强度梯度的梯度计算部分,确定使用第一阈值强度梯度满足颜色模糊条件的像素是可能的颜色模糊的第一颜色模糊确定部分 像素,以及第二颜色模糊确定部分,其检测彩色图像中的饱和像素,以及当饱和像素和可能的颜色模糊像素之间的距离在第二阈值内时,确定可能的颜色模糊像素是颜色模糊 像素。 第一和第二颜色模糊确定部分根据可能的颜色模糊像素的亮度和色度中的至少一个来改变第一和第二阈值。
