Abstract:
An image producing apparatus comprising:a power controller for reducing power fed to an output amplifier of a CCD during exposure of the CCD, and for restoring the power fed to the output amplifier to that of a level before reduction in a predetermined time period before an image signal produced by the CCD is transferred; and a correcting device for correcting offset of the output amplifier based on a signal output from the output amplifier after restoration of the power fed to the output amplifier, and before the transfer of the image signal, wherein when an output signal from the output amplifier stabilizes after the power fed from the output amplifier power source circuit to the output amplifier to transfer analog image data accumulated in the form of charges, the correcting device produces a correction signal for correcting the offset of the output amplifier and outputs it within a predetermined time period to the output amplifier, thereby correcting the offset of the output amplifier.
