thereectedlightisledthroughmirrors,alensandaslittoCCDwhereoptical-to-electricalconversion
is performed, converting the optical image data into an electrical (analog) signal. This analog signal is
changed to a digital signal, which then undertakes various corrective processes necessary for image
formation. After that, arithmetic operation is performed on the digital signal, which is then transmitted
to the data writing section.
