摘要:
PROBLEM TO BE SOLVED: To obtain an image processing method in which a defective pixel address memory for static correction is not increased, and correction omission of a defective pixel or deterioration in resolution due to defective pixel correction does not occur.SOLUTION: With respect to a difference absolute value between an average signal value of a block with a predetermined size including a defective pixel detection target pixel and a signal value of the defective pixel detection target pixel, it is determined whether or not the defective pixel detection target pixel is a defective pixel with a first threshold and a second threshold which is larger than the first threshold (steps ST 1 to ST 6). Next, when the difference absolute value is larger than the first threshold and smaller than the second threshold, a defective pixel address is registered in a defective pixel address memory as a target for static correction, and when the difference absolute value is larger than the second threshold, a defective pixel is determined as a pixel to which dynamic correction is performed (steps ST 8 to ST 12).

要解决的问题:为了获得不增加用于静态校正的缺陷像素地址存储器的图像处理方法,并且不会发生由于缺陷像素校正引起的缺陷像素的校正省略或分辨率劣化。 解决方案:关于包括缺陷像素检测目标像素的预定尺寸的块的平均信号值与缺陷像素检测目标像素的信号值之间的差异绝对值,确定是否 缺陷像素检测目标像素是具有大于第一阈值的第一阈值和第二阈值的缺陷像素(步骤ST1至ST6)。 接下来,当差分绝对值大于第一阈值且小于第二阈值时,将缺陷像素地址作为静态校正的目标登记在缺陷像素地址存储器中,并且当差分绝对值大于第二阈值时 将缺陷像素确定为执行动态校正的像素(步骤ST8至ST12)。 版权所有(C)2012,JPO&INPIT
