10-2.Ccd Sensor - Minolta CF1501 Service Manual

10-2. CCD Sensor
• A reduction-type color CCD sensor is used.
• Each of the R, G, and B CCD chips is placed in a line with a given clearance from the
adjacent chip and provided with a color filter.
• The interval at which each of these CCD chips scans the image on the surface of the
Original Glass is predetermined through the lens and mirrors.
• The deviation produced in the scanning position of each pixel is therefore corrected by
"4. Line-to-Line Variation Correction" of the IR image processing.
• The CCD sensor offers a resolution of 600 dpi on the surface of the Original Glass.
• Each of the R, G, and B chips has 7,500 effective pixels.
