Image processing apparatus and operating method thereof

The invention relates to an image processing apparatus and an operating method thereof. An image processing apparatus includes a target pixel detector configured to detect a plurality of target pixels that generate noise among a plurality of pixels included in an image sensor. The image processing apparatus further includes a target pixel corrector configured to change target pixel values of the plurality of target pixels by using an average pixel value of adjacent pixels included within a preset range based on a position of each of the plurality of target pixels. The image processing apparatus further includes a target pixel compensator configured to compensate the target pixel value using an accumulated value obtained by accumulating values corresponding to a decimal fractional part of the average pixel value. 本申请涉及图像处理装置及其操作方法。一种图像处理装置包括目标像素检测器，其被配置为检测图像传感器中所包括的多个像素当中的产生噪声的多个目标像素。图像处理装置还包括目标像素校正器，其被配置为通过使用基于多个目标像素中的每一个的位置而在预设范围内所包括的相邻像素的平均像素值，来改变多个目标像素的目标像素值。图像处理装置还包括目标像素补偿器，其被配置为使用通过累积与平均像素值的十进制小数部分相对应的值而
