Abstract
A CCD-defect compensating method for a camcorder is disclosed including the steps of: sequentially delaying input pixel data; operating the values of pixels preceding and behind two stages from an nth pixel, and comparing the operated value with a reference level value to detect the presence or absence of a defect; averaging the pixel data two stages preceding and behind the nth pixel having the defect, to thereby obtain the nth pixel data; deciding the position of the defect to thereby generate a defect compensating control signal; and selectively compensating only for the pixel data averaged in the averaging step or the pixel data having the defect and delayed in the pixel delaying step, and outputting the compensated data with the original (externally input) pixel data.
