3 CCD COLOR LINEAR IMAGE SENSOR
The
碌
PD3725A is a high sensitivity 5000-bit
脳
3 CCD (Charge Coupled Device) color linear image sensor which
changes optical images to electrical signal and has the function of color separation.
The
碌
PD3725A has 3 rows of 5000-bit photocell array and 6 rows of 2500-bit charge transferred register, so it is
suitable for high resolution color image scanners and digital color copiers.
