Patent ID: 7027089

Claim:
An image sensor comprising: an image sensing means for receiving an image information of an external objects to thereby perform a signal processing with the image information; a defective pixel address storage unit to store addresses of defective pixels by using a fuse blowing technology, the addresses of the defective pixels being detected through a wafer level test for the image sensor, wherein the defective pixel address storing means includes: a row address selection block for storing a first information representing whether or not at least one defective pixel is present on each row of the pixel array and outputting row address selection signals corresponding to the first information to the image sensing block; a column address storing block for storing a second information of column addresses of the defective pixels and outputting column address selection signals corresponding to the second information to the image sensing block; and a selection bit block for storing a third information for correctly matching the first information with the second information to thereby output matching signals corresponding to the third information to the image sensing block; a defective pixel compensation unit to receive the address information of the defective pixels from the defective pixel address storage unit, to substitute data of normal pixels around the defective pixels for data of the defective pixels.
