Abstract
A color interpolation method of an image sensor including a pixel array which green, red and blue pixels are arrayed in Bayer pattern is provided. The method includes: calculating a first average value of first values filtered by green pixels on even rows and a second average value of a second values filtered by green pixels on odd rows; comparing a value difference between the first average value and the second average value with a standard value; and performing one of a normal interpolation method and a compensation interpolation method with respect to the values filtered by the green pixels according to the comparison.
