ABSTRACT:
An image sensor capable of repairing column readout circuits includes a pixel array, a column readout circuit array, an addressing unit and a repairing unit. The column readout circuit array includes a plurality of column readout circuit group and a redundant column readout circuit group, which is placed on a side of the plurality of column readout circuit groups and consists of a specific number of redundant column readout circuits. The repairing unit is utilized for shifting in order pixel column groups, which are originally coupled to column readout circuit groups starting from a first column readout circuit group having defects, to couple to the column readout circuit groups next to the first column readout circuit group and the redundant column readout circuit group.
