Provided is a lens shading correction device and method in an image sensor. The device comprises a brightness weight storage unit, an input image divider, and an input image brightness correction unit. The brightness weight storage unit stores a brightness weight for allowing one of representative brightness values to be a representative brightness value of a reference image block having a maximal representative brightness value. The input image divider blocks and divides an input image into input image blocks. The input image brightness correction unit corrects a brightness of the input image by multiplying brightness of input pixels by brightness weights.
