15.1.1. CCD Board
Function
Photoelectric transfer by CCD for an imaged object
- CCD (IC1101)
Effective pixels: 768 x 494
Power-supply voltages: 12V, -5V
Image size: opposite angle 4.5 mm (1/4 SIZE)
CCD is driven by horizontal drive signal (H1, H2, RG) and vertical drive
signal (V1~V4) that are output from a VIDEO board. The object focused
by lens unit are converted to electronic signal. This electronics image
signal is read by drive signals and output to IC1001 (7pin) Q1101.
