The presentc invention provides a pixel array of an image sensor, an image sensor having the same and a method for automatically compensating a black level of an image sensor. The inventive image sensor is able to prevent degradation of properties of the image sensor with regardless of applied conditions. To achieve this effect, an image sensor having a pixel array, includes: a first pixel group including N and M numbers of unit pixels, where N and M are integers; and a second pixel group being arrayed in one and the other sides of the first pixel group in a column direction so as to evaluate an offset value of a black level with respect to the unit pixels.
