Patent ID: 7336850

Claim:
A method for concealing a dark defect in an image sensor, comprising the steps of: setting a window including five sequential pixels, a first pixel P 1 , a second pixel P 2 , a third pixel P 3 , a fourth P 4 and a fifth pixel P 5 , from a plurality of pixel data sequentially outputted, the third pixel and the fifth pixels P 3 and P 5 being identical in Bayer color with each other and the second and the fourth pixels P 2 and P 4 being identical in Bayer color with each other; calculating an average value ‘α’ of the first and the fifth pixels P 1 and P 5 and a plurality of ‘α/n’ obtained by dividing the average value ‘α’ by ‘n’, ‘n’ being a multiple of 2; selecting one of the plurality of ‘α/n’; comparing a threshold value ‘α+α/n’ calculated by adding the average value ‘α’ to the selected ‘α/n’ with a value of the third pixel P 3 in size; and omitting a concealment of the dark defect when the threshold value ‘α+α/n’ is greater than the value of the third pixel P 3 .
