Abstract
The present invention is related to a compensation method for a series of synthesized image signals generated by a double-side readout type of CCD which includes the steps of: a) comparing the first two of the series of synthesized image signals with a reference signal to obtain a first and a second compensating signals, respectively; b) serially comparing each signal of the series of synthesized image signals with the reference signal to obtain a series of difference signals; and c) compensating the series of synthesized image signals according to the first and the second compensating signals and the difference signals, to make every two of the resulting series of synthesized image signals bearing consecutive ordinal numbers substantially equal to each other in potential level. The present invention also relates to a compensation apparatus for implementing the present compensation method.
