    摘要: An image sensor includes a storage unit configured to store at least a portion of image data, a homogeneous pixel determination unit configured to determine whether dead pixels exist in homogeneous pixels having the same color characteristic as a center pixel in a window of the image data, and an offset correction processing unit configured to calculate a difference value between the center pixel and homogeneous pixels determined as normal pixels by the homogeneous pixel determination unit, and correct a center pixel value by using the calculated difference value.

    摘要: An image sensor includes a corrector configured to receive a bayer raw data of a pixel array and output a corrected pixel value by correcting a dead pixel occurring in the pixel array, a memory configured to store the corrected pixel value updated in real-time, and a controller configured to control the real-time updating of the corrected pixel value to be stored in the memory, wherein when the corrector corrects the dead pixel in response to a clock, the corrector uses the corrected pixel value which is updated and stored in the memory in response to a previous cycle of the clock.
