ABSTRACT:
A streaking correction signal generating circuit includes a light-shield waveform detecting unit configured to detect signal levels of respective lines in a horizontal light shield by using an output signal of the horizontal light shield of an image sensor; a black level detecting unit configured to detect a black level by using an output signal of a vertical light shield of the image sensor; and a subtracting unit configured to subtract the black level detected by the black level detecting unit from each of the signal levels of the respective lines in the horizontal light shield detected by the light-shield waveform detecting unit so as to generate streaking correction signals of the respective lines.
