Image Sensor (Scanner)
An Image Scanner converts images that have been scanned optically into digital images. Typical Image Scanners available in the current market are either Charge-coupled Device (CCD) or Contact Image Sensor (CIS) where lights is predominantly used to capture the image by passing the images to be scanned over an array of sensors with Red, Green and Blue filters or LEDs.
Most of the Image Scanner device is die-attached with a row of CCD (usually 15 dies) and a TG die. The CCD dies are attached at pre determined position to ensure that there is no distortion or noise to the scanned image.
