Abstract: The invention relates to a method for bad pixel classification for an image sensor having a plurality of sensing elements. The method includes capturing a plurality of images using the image sensor, determining based on a pre-determined criterion, using an image of the plurality of images and a threshold value selected from one or more pre-determined threshold values, whether a sensing element in the image sensor is defective to generate a vote, wherein a threshold parameter associated with the pre-determined criterion is set to the threshold value, tallying the vote to generate a voting count by performing iterations of the determining step using different images of the plurality of images and different threshold values of the one or more pre-determined threshold values, and classifying the sensing element as a bad pixel if the voting count exceeds a pre-determined classification threshold.
