A scanner with poorly aligned colors will produce an image that appears blurred. In the current Line by Line system, the CCD captures the red, green, and blue information simultaneously, but the final processing of these colors are done separately before being sent to the software. Unfortunately, misalignments of color occur because the scanner's motor is in continual motion and must rely on a timing system that does not allow perfect synchronization. This color misalignment problem could only theoretically be corrected if the scanner's motor were to physically stop completely before each line is scanned. Because of this, there is little misalignment problems inherent with a scanner using Pixel by Pixel technology.
Colors are sharp and the image itself appears more properly focused.
These other technologies refer to the number of times the image must pass over the CCD before they are processed. Pixel by Pixel and Line by Line refer to the actual processing stage itself. Testing a Scanner for Pixel by Pixel Capability Pixel by Pixel technology is not marketing hype. Indeed, the results of Pixel by Pixel scans are very clearly seen, even by typical non-professional scanner users. To determine if a particular scanner uses Pixel by Pixel technology, scan a page of black text in RGB color mode.
