Mechanism
Halogen lamp
Color filter
Film
CCD
Lens
Light from a halogen lamp is passed through red, green, and blue filters,
and the film is irradiated with each kind of light. The light transmitted
through the film is focused into an image on a linear CCD through an
image formation lens.
The film information on which photoelectric conversion is performed by
the CCD, undergoes A/D conversion and signal processing after being
amplified, and is sent to the host computer via the interface.
