CIS Element Design
The CIS Element consist of 3 major parts: sensor, lens and light source.
The Light source is 3 LEDs in RGB that are lit one at a time.
The sensor consists of 10368 individual monochrome sensors.
The purpose of the lens is to channel the light from the “pixels” on the image to the
sensors.
There is no magnification in the lens (1x1).
Due to the very short focal length, the focus depth is limited.
The original has to be in contact with the surface of the glass plate in order to be in focus.
The LED’s flash one at a time,
capturing one color at a time.
