Abstract
Using an approximation generally satisfied in practical applications, an expression for the deviation of the CCD transversal filter transfer function due to the device CTI is obtained. Then a very simple algorithm for the coefficient modification is derived to compensate for the CTI effects, which are thus reduced by more than an order of magnitude. Computer simulations finally show the validity of the obtained results.
