Abstract:
1. A method of defective pixel address detection for an image sensor, comprising: (a) comparing a defective pixel address with a sensor address, wherein the defective pixel address is stored in a memory element in advance when the image sensor is tested; (b) outputting a defective pixel flag if the sensor address is equal to the defective pixel address; (c) increasing an index value by one unit and returning to the step (a); (d) comparing the defective pixel address with an empty signature if the sensor address is not equal to the defective pixel address; (e) increasing the index value by one unit if the defective pixel address is equal to the empty signature, and returning to the step (a); and (f) returning to the step (a) if the defective pixel address is not equal to the empty signature.
