ABSTRACT:
A signal correcting device of photoelectric conversion equipment having a series of photoelectric conversion devices, including a shaded pixel section and an unshaded pixel section, employs a memory which stores data obtained when the series of photoelectric conversion devices is in a dark state beforehand, as at the time of manufacture and assembly. The stored data is retrieved during actual use of the photoelectric conversion equipment and is utilized in the correction of output signals from the unshaded photoelectric conversion devices.
